Cellulose based insulation materials are treated with phosphate compounds to provide flame retardant properties and reduce or eliminate the propensity of the cellulose based materials to ignite and propagate flame or smolder. The phosphate compounds may be blended with the cellulose based material in a dry process. Alternatively, the phosphate compound may be dissolved or dispersed in water or other solvent and sprayed on the cellulosic material. The cellulose material is then dried prior to use. The treated cellulose materials may be further conditioned prior to use by heating to between 30° C. and 100° C. for 12 to 48 hours.

BIOBASED POLYOLS FOR POTENTIAL USE AS FLAME RETARDANTS IN POLYURETHANE AND POLYESTER APPLICATIONS

Номер: US20130150475A1
Автор: Benecke Herman P., Garbark Daniel B.
Принадлежит: BATTELLE MEMORIAL INSTITUTE

The invention provides for new flame retardant non-furan dicarboxylic acid (FDCA) based polyols; oligomers and polymers made from these new polyols with flame retardation properties; and methods of using them as a part or all of the flame retardation composition/material, such as foams and binders. 9. The foam article of claim 8 , wherein the total amount of polyols claim 8 , polyol mixtures claim 8 , and/or oligomers are present in the amount of about 0.25 wt % to about 78 wt % based on the total weight of the foam article. The invention provides for non-furan dicarboxylic acid based flame retardant polyols, and the use of these polyols in polyurethane and/or polyester applications.Polyols are materials used in a wide variety of applications, such as flame retardancy, cross-linkers, chain extender, chain terminators, and/or polyurethane synthesis. U.S. patent application publication 2008/0182944 (Benecke et al.) describes a series of new polyols used in formaldehyde free binders in fiberglass applications. Benecke et al. disclose that the new polyols are based on furan dicarboxylic acid (FDCA), and these polyols are disclosed to be useful as a binder. However, the current pricing of FDCA is too high for industrial use. Until FDCA is more cost effective, alternative polyols are needed.Furan-containing polyols, compounds or materials (“furan compounds”) are known for their char formation when heated to high temperatures, and as such, they are regarded as possibly having some flame-retardant properties when combined with other known flame-retardants, cf. U.S. Pat. Nos. 4,029,611; 3,865,757; 4,318,999, and U.S. patent application publication no. US 2011/0124839. The other known flame-retardants are considered to be main contributor to the flame retardation properties of the foam; while the furan compounds were used along with other catalysts for promoting carbodiimide linkage so that the resulting foams could have better processability without losing any flame ...

The present invention relates to compositions obtainable by reaction of a hydrate of magnesium sulfate with diammonium hydrogenphosphate and a further inorganic substance, especially anhydrous magnesium sulfate. The invention also relates to the production of the compositions and to the use thereof as flame retardants. 1. Composition , obtainable through conversion of at least one hydrate of the magnesium sulfate with di-ammonium hydrogen phosphate ((NH))HPO) and with a further inorganic material which is selected under zeolite , anhydrous calcium chloride and anhydrous magnesium sulfate and their mixtures.220-. (canceled) This invention concerns compositions which are available through the conversion of a hydrate of the magnesium sulfate with di-ammonium hydrogen phosphate and a further inorganic substance, in particular anhydrous magnesium sulfate. The invention also concerns the manufacture of the compositions and their utilization as flame-retardants.For the thermal insulation of new and old constructions, insulation materials are employed which are manufactured in many cases of renewable or recycled organic fiber materials, such as excelsior, wood chipboard, sheep's wool or scrap-paper. Since such materials are often comparatively inflammable, flame-retardant is generally added to them during their processing to insulation materials. Certain salts and salt mixes are used as flame-retardants, which are usually mixed with the organic fiber materials in fine-ground form. In this connection, mixtures of borates with further salts, such as in particular magnesium sulfate (MgSO7H2O) have proven themselves, where magnesium sulfate contributes to the flame retardation, particularly through its high hydrate content. Since recently the toxicological harmlessness of borates and boric acid is coming increasingly into question, a requirement exists for alternatives.Basically it is known that ammonium phosphates, such as for example (NH)PO, (NH)HPOand (NH)HPO, have fire- ...

The invention relates to flame-retardant foam coatings for textile sheet products, wherein the coatings include plate-like expandable graphite which has a reduced salt content and a particle distribution with a proportion of >80 percent by weight having a diameter of at least 0.2 mm, and/or a minimum proportion of 70% having a mesh size of >50 mesh (0.3 mm), at least one binder and at least one foam stabilizer, and also processes for the production thereof, the use thereof for producing textile sheet products and also textile sheet products having such flame-retardant foam coatings. 1. A process for producing a flame-retardant , textile sheet product comprising a textile substrate layer , which comprises:a) reduction of the salt content of plate-like expandable graphite by additional washing, to a proportion of below 0.8% by weight, on a basis of total weight of the plate-like expandable graphite which has been reduced in salt, the plate-like expandable graphite having an average plate diameter of at least 0.5 mm, and/or a minimum proportion of 70% by weight having a mesh size of >50 mesh (0.3 mm) being selected,b) production of a paste comprising at least one binder, at least one foam stabilizer and expandable graphite which has been reduced in salt as specified in a),c) mechanical foaming of a paste produced according to b),d) coating of a textile substrate layer with a foam produced according to c),e) drying of the foam layer, andf) optionally pressing of the foam layer after drying.2. The process according to claim 1 , wherein a woven claim 1 , knitted or non-woven textile substrate layer is coated in step d).3. The process according to claim 1 , wherein the drying in step e) is carried out at a temperature of 80-100° C. to produce an unstable foam.4. The process according to claim 1 , wherein the drying is carried out at a temperature of 80-100° C. and crosslinking is carried out at 120-170° C. in step e) to produce a stable foam.5. The process according to ...
