Procedure for the covering of surfaces

The invention concerns a procedure for the covering of surfaces and in particular a procedure for the covering of a surface, for example a glass, a ceramic(s), Kohlemtoff, Meta11oder organic polymer surface with aluminophosphate, with which a solution of an aluminophosphate connection is applied, for the distance of the solvent is heated up and the coat hardened, which is characterized by it that one uses a coat solution, the phosphate complex of aluminum, halogenhaltigen in water or an organic 1.6sungsmittel, like e.g. aliphatic alcohols with 1 to 10 carbon atoms, esters, multi-valued alcohols or glycol star, or a mixture of these, which chemically bound water or a chemically bound alcohol with 1 to 10 carbon atoms contains, and if necessary an surface-active means , for the distance of the solvent on a Tempel0 nature exhibits by mindestem 80°C heated up and the coat hardens and so into an aluminophosphate coat transferred. The designation phosphate covers phosphoric acid esters and sour phosphates. Because of their easy availability the use of aliphatic alcohols with 1 to 4 carbon atoms, for example methanol, ethyl alcohol, N propyl alcohol or isopropyl alcohol is preferred. With preferential Ausfühmngsformen of the invention ethyl alcohol is used, since the phosphate complexes, which contain ethyl alcohol, can be formed particularly easily in firm form in high yield. The halogen in the halogenierten phosphate complex of aluminum is preferably chlorine, however the connections can contain also different halogens, for example bromine or iodine. The relationship of the number of Grammatome aluminum to the number of Grammatome phosphorus in the phosphate complexes of aluminum can vary within wide range, for example from 1: 2 to 2: 1, amounts to however preferably essentially 1: 1, since according to invention the phosphate complexes, which exhibit such a relationship, used with the procedure, decompose at low temperatures directly under formation of aluminum orthophosphate, which exhibits a larger chemical stability and refractoriness than an aluminophosphate, which from Phospha omplexen with other conditions one forms. The relationship of the number of Grammatome aluminum to the number of Grammatome halogen in the phosphate complexes amounts to essentially i: 1. According to invention the phosphate complexes used with the procedure can be monomers or polymere. The structure according to invention of the phosphate complexes used with the procedure is not yet completely clarified, and some of the chemically bound alcohols are probably rather in the form of groups - OR as in the form of whole molecules bind. For example 1 to 5 mol water or alcohol can contain the monomers the forms or the repeating units of the polymere forms according to invention of the phosphate complexes used with the procedure. The number of molecules of water or alcohol 4. amounts to most frequent sometimes can the phosphate complexes of molecules of water and also by alcohol exhibit; thus they contain for example both chemically bound water and a chemically bound alcohol, whereby the number of such molecules amounts to for example 2 to 5. An example of one with the procedure according to invention used phosphate complex is the phosphate complex, ethyl alcohol contains nnd the empirisehe formula AIPCIHz5 CsOs exhibits. Infrarotund Röntgemtrahl characteristics of the connections is described later. This connection alsAluminiumchlorphosphat äthanolat designated and designated for reasons of the simplicity in folgendenACPE, however it is natural that this designation in no way a certain mole - külstruktur the connection suggest is. An example of one with according to invention the procedure used phosphate complex, which contains chemically bound water, is the phosphate complex with chemically bound water and the empirical formula A IPCIH i: OS Infrarotund X-ray characteristics of the connection are described later. This connection is called Aluminiumehlorphosphathydrat and designated for reasons of the simplicity ACPH, however it is natural that this designation is in no way a certain molecular structure of the connection suggest. A further example one with the procedure according to invention phosphate complex which can be used is that one, the bromine and ethyl alcohol contains and the empirisehe formula A1PBrH2 C in such a way “exhibits. This connection as if itäthanolat designation and for reasons of the simplicity ABPH designated however it is natural that this designation in no way a certain molecular structure of this connection suggest so11. The phosphate complexes, which contain at least a chemically bound molecule and water and/or or alcohol, which can be used with erfindungsgemä the EN procedures, are generally in water and organic solvents, in particular in polar organic I/ösungsmitteln, soluble under formation of coat solutions. Phosphate complexes, which contain chemically bound water molecules, are soluble in water. Their solubility in solvent mixtures rises with rising portion of the polar solvent in the solvent mixture. L0sungsmittel, which contain water and an organic solvent mixable with water, are particularly appropriate for the loosening of the phosphate complexes. The L6slichkeit rises generally with reduction of the pH value of the solution and to a pH value of under 3, 5 in aqueous solutions is preferably adjusted, in order to keep a maximum solubility upright. Those according to invention to using connections result in generally viscose rayon solutions in water. If filr the coat composition an organic solution is used, then this contains a polar solvent, in particular an oxygen-containing polar solvent, particularly suitably is preferably aliphatic alcohols with at the most 10 carbon atoms, esters, Polyole and glycol esters. At most preferentially are aliphatic alcohols with 1 to 8 carbon atoms, for example methanol or ethanol. The solvent can be ungsmittelgemisch a RST. The relationship of the number of Grammatome aluminum to the number of Grammatomen phosphorus in the composition can vary over a wide range, for example from 1: 2 to 1, ö: 1, amounts to preferably imwesentlichen 1: 1, since an aluminophosphate, which was formed by decomposition of a composition, which exhibits this relationship, is particularly stable. The phosphate complexes used into the Überzugszusammensetzungeu or a mixture, which contain this phosphate complex, for example its solutions, can form for example by conversion of aluminum or one aluminum connection, preferably a phosphoric acid ester or a connection, phosphoric acid or a phosphoric acid ester for a halide, with water or alcohol and phosphoric acid, can, be manufactured. The aluminum halide can be a simple halide or a Oxyhalogenid or a Aluminiumalkoxyhalogenid, for example Aluminiumäthoxychlorid. To other suitable aluminum connections aluminum min umalkoxyde, fuel element [sptelsweise Aluminiumäthoxyd belongs. If aluminum or an aluminum connection different of a halide is used, the presence of a halogenhaltigen acid is necessary. Mixtures of Hydroxyverbindungen can be used. To substances, which are capable to form phosphoric acid or a phosphoric acid ester belong Phosphorpentoxyd, Phosphoroxyhalogenide and Phosphorhalögenide. An aqueous solution can be used by phosphoric acid, appropriately 88 /oige a solution in water, although preferably gewähr88 carries out be should that no more than about 6 Gew. - a/o water, related to the total weight of the reaction mixture, is present, if a phosphate complex with water or alcohol is manufactured, since thereby a loss at yield is avoided. The sequence, in which the reaction components are added each other, is not critical; it is preferred adding the aluminum connection to water or the alcohol and converting then phosphoric acid or the phosphoric acid ester with the received mixture. It can be appropriate to solve the aluminum connection in a suitable solvent which either the used water (in presence of a halogenhaltigen acid) or the used alcohol or an inert solvent to be can, before it is continued to convert. This is then appropriate in particular, if the reaction is accomplished at a temperature, with which water or the alcohol a solid is or if the water or the alcohol a pure Lösnngsmittel for the aluminum connection represents. The highest yields at the product are received, if the molar ratio from aluminum to phosphorus during the conversion essentially 1: 1 amounts to. The conversion can be accomplished within a far temperature range, however generally a temperature unter60°C is preferably preferred and from 0 to 50°C, in order to receive optimal yields. If it is for example gewiinscht, to keep upright water-free conditions, then the UmsetT is accomplished ung preferably in an atmosphere of a dry inert gas, for example nitrogen. With ferries according to invention phosphate complexes which can be used, which contain chemically bound water molecules, or a mixture, which contain this phosphate complex, can be received, by another phosphate complex, which contains, is hydrolyzed a chemically bound alcohol or as the above-mentioned reactions are accomplished in presence of water. In this way it is possible to replace the alcohol totally or partly by Wassermolektlle. It is particularly appropriate to use as raw material the phosphate complex of the empirical formula AIPCIH2 sports club O8. The partially hydrolyzed product can be only one substance, which contains both chemically bound water and alcohol, or she can be a mixture of for example completely hydrolyzed and unhydrolysierten molecules of the original phosphate complex. Polymerization of the hydrolysis product can accompany the hydrolysis, so that products with higher molecular weight develop. The hydrolysis can be caused by each suitable means, however it is for many connections which can be used according to invention ausreiehend to add the substance water at room temperature or to hold the connections more tlber a sufficient period in contact with damp air. Appropriately this can be accomplished, as the connection in a river is liquefied by damp air, preferably at a temperature under 80°C. The phosphate complex which can be used with the procedure according to invention can without isolation from the mixture, from which it is educated, or after distance of a part of the Reaktiomprodukte to be used, then the raw reaction product, which will receive on production of the preparation, can be used directly for the covering of surfaces. Alternatively can a solid, which contains the phosphate complex, from which are tteaktiomgemisch separated and used for the production of a coat composition or continued to clean if necessary before the use. The separation of the product can be caused in each suitable way, for example by means of losses by cooling, evaporation of the volatile components or addition of a further component with following filtration or Cbromatographie. Sometimes spontaneous failing of the product from the reaction mixture takes place, and the separation is reached simply by filtration. The product can be washed, for example with ethanol. The mother liquor staying after separation of the product can be rejected or for further use again into the cycle be rüekgeführt, preferably after cleaning of unerwümchten reaction by-products. The phosphate complexes to decompose see when warming up under education on aluminophosphate in amorphous form or into different crystalline Formen.Die temperature, at which the aluminophosphate develops, depends on the respective phosphate complex heated up, amounts to however usually 80 to 500°C and is frequently under 100°C. It is appropriate to warm up the phosphate complex for the formation of Aluminiumphnsphat to a temperature from 100 to 150°C. Surprisingly crystalline forms can be received from AIuminiumphosphat at low temperatures, which üblieherwelse only when warming up Alum result [ninmphosphat on temperatures over 800öC. The aluminophosphate can be further warmed up, for example for the change of its crystalline Vorm. If the relationship of the Grammatome aluminum to the Grammatomen phosphorus in the Phnsphatkomplex 1: Consequently I amounts to chemically particularly stable, has the produced aluminophosphate the same relationship from aluminum to phosphorus and is. The characteristics from Alumininmphosphat are in such a manner that wümchenswerte Eigemehaften is lent according to invention manufactured to the coats such as firmness, refractoriness or chemical inertness. Solutions according to invention of the phosphate complexes used with the procedure know appropriately additional components, for example materials, which support the further processing of the solutions or which from the solutions developing products affect in wtlnschenswerter way, contained. So organic materials, in particular polymers, in the solution of the phosphate complex, can be loosened be fallen in particular in those, in which the solvent is an organic solvent. Additional components, for example pigments, coloring materials or Fflllstoffe, can be likewise dispersed in the solution of the phosphate complexes. It particularly preferred that solution phosphate complex material or materials contains, which the physical nature of of the firm phase of AIuminiumphosphat, which is formed from the solution, for example by warming up, to adjust. If the solvent contains water, a Kristallisattonsstabilisator becomes preferably, for example feintetliges Silieiumdioxyd or alumina or a nucleation activator or a catalyst, a beispieisweise Dibutylperoxyd or calcium, Magnesiumoder sodium chloride use. If the solution of the phosphate complex is not aqueous, for example if the solvent is ethanol, becomes preferably a boric acid ester or ether or a silicic acid ester or - ethers, for example methyl borate, Trimethoxyboroxin or ethyl silicate used, in order to unterdrtlcken the crystallization from aluminophosphate to. Solutions of the phosphate complexes in water or organic Lösungsmittelu, which can be used with the procedure according to invention, can be used, in order to produce coats from aluminophosphate for a VielzahI from surfaces to, and zw. for example by distance of the D3sungsmittels and vorzllgsweise warming up of the matured coat. The duration of the heating up amounts to preferably at least! 0 min. The form of the production aluminophosphate depends among other things on the temperature, to which the coat is warmed up, although a temperature of at least 80°C is sufficient generally, umeinen coat from aluminophosphate to form. Preferably the coat is warmed up to a temperature of 100°C. The coat can be further warmed up, in order to polymerize the deposit or to change the crystalline form from aluminophosphate to, in particular with Überztlgen, which are produced from a solution of a phosphate complex in organic solvents, can the aluminophosphate from the crystallization be prevented, as into the practicing course composition boric acid esters or - ethers or silicic acid esters or - ethers, for example methyl borate, Trimethoxyboroxin and ethyl silicate, are trained. Organic materials, preferably polymers, can be loosened in the solutions, of which the coats are made, whereby coats develop, which contain an organic material and Alumintumphosphat. It is favourable to add to the coat solution a suitable wetting agent in order to promote an even covering. Other components. for example pigments, can be trained into the coat, by being added to the coat solution. After erfindungsgemäf the EN procedure is covered thereby a document or a carrier, for example a glass, a Kohlemtoff, a metal, a ceramic(s) or an organic polymers, with a warm-stable, inert, transparent, hard Pilm by aluminophosphate. The carrier solI preferably capable its of bearing a temperature of at least 80°C; with documents, which do not bear this temperature, coat preferably after procedures warmed up, with which the document, on which it deposited, is not warmed up, for example by short wave treatment. The coat from aluminophosphate is in many way useful, for example as protection of the document against corrosion, warmth or abrasion. Each desired form of the Trägeroberfläehe can be covered, for example for fibers, films, powdered and made articles. ACPE, in particular as solution in a polar solvent, is particularly suitable for the production of a coat solution. Surfaces, which are covered with aluminophosphate, can be covered with a further component, for example with a metal such as aluminum. Solutions of phosphate complexes are particularly suitable for the covering of glass, since the connection between the Glasoberfläehe and aluminophosphate is very good. It is particularly favourable, if the coat is applied directly, after the glass from its melt is formed. The conciliation of the glass fibers by means of solutions of phosphate complexes is particularly favorable. The solution is applied preferably immediately after pressing the fiber out on the glass fiber. After applying the solution is dried either in the vacuum or by warming up or by a combination of both procedures. Warm up the coat under formation of aluminophosphate, which is called “hardnesses” here, can be combined with the drying stage. If for example Äthylcellosolve is used as solvent for the phosphate complex, hardening and drying can be accomplished with the boiling point of the solvent, which 135°C amounts to. If however the solvent is removed at a temperature under for instance 80°C, further warming up of the coat is necessary at a temperature from at least 80°C to the execution of the hardening. Solutions of the phosphate complexes in organic Lösungsmittelu can contain materials such as Organosilane or organic resins such as Hydroxypropylcellulose, Epoxyharze or urea formaldehyde resins mitniedfigem Moleknlargewicht, in order to support the education of an impermeable coat; the resin should be capable of bearing a temperature of at least 100oc and should vorteilhaften¢eise be capable, sees at this temperature interlacing. Into the coat solutions additives can be trained to the Reguäerung of the Kristallisatinn, for example methyl borate or Äthyisilikat. On the covered glass other coats, for example a resin, can be applied. Glass, which is covered with aluminophosphate, can be treated with a means, for example a Organosiliciumverbindung, around the training of the glass fibers into the Harzgefäge to supporting. Such a covered glass is considerably more kompäkter than not covered glass and resistant against abrasion. It is also against chemical attack of for example alkaline materials and can from there in contact with Materialien.die usually glass be damaged, for example cement, used. Other glass forms than glass fibers can to be besehrieben, covered as above, for example glass plates and glass articles generally. Glass, which is covered with aluminophosphate, can be covered further with a material, which sticks to aluminophosphate, for example for aluminum. Glass fibers, which were covered after erfindungsgemäla the EN procedure with aluminum, can form easily useful Kompositmaterialien from glass fibers and aluminum, for example by presses, preferably at a increased temperature, for a mass of covered glass fibers. The use from phosphate complexes to the production of a coat of aluminophosphate for carbon fibers is particularly favourable. The carbon fiber can be immersed for example in solutions of the phosphate complexes in water or organic Lösungsmitteha, for example polar solvents such as ethanol; the surplus solution can be poured off and the fiber be dried and zw., appropriately by warming up the fiber in air at temperatures from 90 to 250°C. If necessary the fiber in for example trichlorethylene before applying the solution can be degreased. The coat can be hardened by warming up, preferably in an inert gas, for example nitrogen, at a temperature over 100°C, appropriately with I00 to 500°C, although, if the Troeknen over for instance 100oc were accomplished, hardening is not always necessary. Coat of aluminophosphate, manufactured such a on Kohlenstoffasem, increases the Wtderstandsfähigkeit of the fiber against oxidation considerably and protects the fiber surface from dfe reciprocal effect between these and other materials, with which it comes into contact. From there a protection of the carbon fibers can be achieved, if they are trained in materials wic melted metals, for example aluminum, in order to reach a reinforcement for the firm metal. A covering of the carbon fibers with aluminophosphate makes it possible to flberziehen the fiber still further with a film from aluminum metal or glass. Kompositmaterialien can be manufactured, as “bundles” are injected by such covered fibers at high temperature. The coat cause-dips nefestere connection between the carbon fiber and an flint-acid material, into which it one brings. The phosphate complexes can be applied as glaze or as decorative coat on clay/tone goods or ceramic(s) articles and are generally for the covering of each body suitable, which forms a firm connection with aluminum-chamfer-chamfered, although it is natural that its use is not limited to examples, with which such firm connections is possible. Keramikfasern, for example asbestos, Siliciumcarbidund boron fibers, can be covered in an appropriate way. Aluminophosphate, which was applied on Metallöberflächen by means of phosphate complexes, supplies coats, which are heat resistantly and electrically isolating korrosiombeständig. The coat of aluminum mini! 5 over and steel is particularly favourable. Metal wires can be appropriately protected by the Überzttge. Corrosion inhibitors, for example Glycerylmonolaurat, can be added the coat solution. Polymere one organic materials, for example synthetic fibers of PP or polyesters, can be appropriately covered with aluminophosphate or a mixture, which contains Alumlniumphosphat and an organic material. Drying and hardening the coat can be durchgefllhrt in each suitable procedure for the heating up, if that bears polymers a temperature of at least 80oC. The invention is more near described by the following Beisptele. Are given to example 1:40 g water-free aluminum chloride to 300 cms exp. of ethyl alcohol. The received mixture will become on 0°C gektthlt, 18, 6 cm 88%igc Orthophosphorsäure drop by drop added, and the reaction mixture is agitated. The conversion is accomplished in an atmosphere by dry nitrogen. The formed white crystalline material is separated from the mixture, washed with ethanol and dried in the vacuum at a temperature of 0oc. One receives so 70 g of the product.
