Liquid lubricant compositions

The invention refers to compositions, yields the achievement of an effective and long andauemdenBeständigkeit against vapor phase corrosion, improved anti-fatigue characteristics and other favourable characteristics by additive of one bes°nderenVerbindungsartzuSchmiermittelzusa mmensetzungen makes possible. Liquid lubricant compositions are created by the invention, which a lubricant contained, which a small quantity of a vapor phase anti-corrosion means of the general formula R l R' - N (X-O) nH exhibits, in soft formula Rftlr alkyl and R' fflr Alto] l or hydrogen stands, R+ R' 1 to 10 KohIenstoffatome contained, for X a group of alkyls with 2 to 4 Kohlemtoffatomen represents and n 1 or 2 is. In these amine connections course genes alkyl groups more geradoder verzweigtkettig and, secondary know prime lire or save. - Alkyls its, so long the total number of the carbon atoms not more largely than! 0 is. In the same way by the symbol X represented the Alkylengmppen can primtiren more geradoder verzweigtketüg and of, be derived secondary or tertiary alkyls. The above general formula shows that the connections hesitated in consideration can be called A1kanolamine. Some examples of such connections are: Mono methyl amino-ethyl alcohol, Dimethylaminoäthanol, Mouoäthylaminoäthanol, MonotRhylaminoäthoxyäthanol, Diäthylaminoäthanol, Diäthylaminoäthoxylithanol, Diisopropylamino lthanol, DibutylaminotRhanol, Dibutylaminolithoxyäthanol, n-Butylamino thanol, Dimethylamino-2-propanol, Diisopropylamino-2-propanol, n-Butyl-amino-2-propanol, Isobutylamino - 2 - propanol, Dimethylamino - 2 - butanol and Dimethylamino l bufanol. The Alkanolamine can be used favourably in the most diverse lubricant compositions. They are particularly effective in lubricant compositions, which water as Komponents or pollution contains, or in Schmiermittelzusammcmetzungen, yield in machines, plants or systems to be used, the conditions are suspended, on which a vapor phase corrosion and/or a Metallsrmlldung are promoted either to present or to absence by water. Some examples of such liquid Schmierrntttel are S hmierölzusammensetzungen on the basis of mineral oils or synthetic oil, for example for use as Krafffahrzeugschmiermittel, like engine oils, transmission oils and dgL, when Hugmsugschmiermittel, including nozzle engine oils, naval lubricants, like Schiffsdiese161e, Industriesehmiermittel, how lvletallbearbeitungsöle oils, Zahnrado and such further ones are included the single-phase Schmiemnsammensetzungen or A beitsflüssigkalten, which water and a synthetic oil contain, like the glycol liquids with a g - stop at water, glycols and Polyglykolen. Further examples of liquid lubricants, which can be improved by the invention, are water in [...] Emulsioncn, like them e.g. as metalworking liquids as Ofenkettensohmiermittel, or than ArbeitsflUssigl¢eiten, wio hydraulic liquids and Gelziebefltlssigkeifen, to be used, the use of the above-mentioned Alkanolaminc with Wasser-inoÖ1oErnulsionen represent a special characteristic of the invention. It was found that the gegenständlichen Alkanolamine is due to their alkaline Chamlders with water in oil Ernulsionen, which are present in an alkaline or sometimes neutral environment compatible and particularly effective. This stands contrary to that so far admitted drinks Inlübitomn, which are inclined to fail in alkalischan emulsions. It was found that the use of the gegenständlichen Alkanolamine improved the Ernulsionen not only a vapor phase corrosion resistance and a Antiermüdungseigemchaften, but also Antiverschlei igenschaften and one extends life lasting lends. The above-mentioned Schmierrnittelzusammemetzungen, both the lubricating oils and the water - in-ÖI-emulsions, know basic oils with Sehmierölviskesi t forged Urspmngs and verschie, t0 of denster characteristics to contain. Examples of some basic oils are mineral oils from different crude oils, how ohölen, which were acid-refined and hydrogecrackt lösungsmittelund, as well as syntheüsche oils naphthenischen and paraffinischefi l, like Olefinpolymere, hydrogenated Olefinpolymere, Allo/lenoxydpolymere, dicarbonic acid esters, fltlssige Phosphomster, monomers and polymere Silikone, ester of multi-valued alcohols and such. 4ä in case of the waters in-ÖI-emulsions can be used the Grund01 and the water in different portions, whereby gewöhulich the water in a quantity from 10 to 70 thread - o of the emulsion is present. Wasser°in-Ö1-Emulsionen with a hearing of hydrocarbon basic oils with a S.U.V. from 50 to 400 is particularly interesting with 38oc. The use of the special All¢anolamine is necessary, around the gewaschten vapor phase rust-resisting property, Antiermüdungseigemchaften and other gewttnschte characteristics too erzielen* the structure and characteristics of these special Monoalkanolverbindungen simmers of importance, since, how late NR [is described ago, is found that/lhrdiche connections do not hmierzusammen eimchließlich alkyl amines and certain Dialkanolverbindungen in S tzungen are so effective. The gegemtändlichen Alkanolamine must be in the Schrniermittel in an effective condition present. They are to be able to arrive in the Sehmiermittelzusammensetzung freely at the effect. The invention is therefore of the use of addition products, complexes od. such from Alkanolaminen with other Korn° potent, with which the Monoa] kano] e blocMert or otherwise in their we] struggled einge h Nm or would be destroyed to differentiate. The superiority of the effindungsgemlfl3en, the above-mentioned All¢ nolamine enthütenden lubricant compositions is shown by the following comparison test series. There m phase anti-rust test with this test the effectiveness of different Iminoverbindung ah I mpfpha nrostinhibitoren measured in Schrniermitteln. In accordance with 13 the Testveffahren a high became 497 ml-Weithalsglasgef 13 the Halfte along that liquid which can be tested pleases to make for E possible ne with a Sandstrahlgebl e and with solvent cleaned steel test plate to the Innemeite of a Zinudeckels with a magnet is fastened, according to which the cover is screwed loosely onto the Glasgeflll3, in order certain breathing. The GeftlB is then adjusted over night up to the Flttssigkeitsniveau into a Wasserbad held 80°C, taken on the day and stored 8 h long at hoof temperature. The Dam - phamn Antirostwirkung of the Fltissigkeit is determined by measurement prozentuellen extent at rusty surface after different Etnwirkungszeiten. The smaller the rust quantity, the more effectively is the inhibitor. The F gebnisse after an induction period of 7 days under the Testbedtngungen, received with water in oil Ernulsionen, are to be inferred from the table 1, against what the Ergehni e is summarized after test periods of 27, 38 and 70 days in table 2.

That Vickers pumpentest, which is a test for the measurement of the Etgemchaften of such emulsions, is accomplished, by circulating the emulsion which can be examined in a Vickers vane-type pump, model V-111-E10 (laid out for 7,65 l/min.). This hydraulic pump is a positive-displacement pump. The rotor possesses 19. Steel wings, which stand with a steel ring in contact and which Potor turns with approximately 1200 UpM. Those! 2 wings and the steel ring are test-weighed before and after. The deficiency in weight represents the Gesamtverschleil3. The Antirosteigemchaften of the tested liquid chains was determined by getting jammed the steel test plate within the Messtngttllledes Vickers Pumpenbehälters. The results are summarized in the table 5. The table 5 shows that the emulsion (test 2), which contains the effindungsgemttl3e AlkanoLamin, better vapor phase anti-rust characteristics possesses, a smaller wear with itself brings and to the emulsion a longer life span lends, lm contrast to it shows the comparison tests 3 to 5, da/3 after approximately 1000 Teststundeudie emulsions, which Butylamin or Isopropylamin HexylaminGemi contains, it vapor phase remainder protective effect perfectly lost, so that not only the attempt plate, but also the pump container had strongly rusted. Further it comes out from the tests that the Fanulsionen the comparison test possesses 3 to 5 very bad chletBeigenschaften, as the high total wear values show. Thus for example tests resulted in 3 and 4 total wear values of 468 and/or 200 mg compared with a Gesamtvemchleiß of only 102 mg of the emulsion of test 9 table Vth “effect of the vapor phase inhibitors in the Vickers Pampentest in the case of 70 kg/crr 80°C, 7,56 after approximately 1000 h dieFanulsionenderVergleich! /min test BetriebsGesamtNr.

A special advantage of the Wasser-in-Ö1-Emußionen according to invention is however their improved Anüermüdungsbest ndigkeit. This is determined by the four-ball fatigue inspection. With this test one lets three lower steel balls run in a suitable race freely, which is propelled by fourth steel nail, which is held in the fodder of the wave of the four-ball fatigue test equipment. One load of 14,96 kg and a speed of 5200 Umdr/min is used. The test is terminated, if one of the balls exhibits a fatigue scar, by which an excessive noise generation and oscillation is produced. The oscillation operates a Sehwingungsschalter in the electric circuit of the Antriebsmotom, by which the test equipment is switched off. The longer the length of time up to the loss is, the more largely is the Antiermtidungseigemehaften of the tested liquid. The results are summarized in the following table VI.
