COMPOSITION FOR FLAME RESISTANT COATING OF WOOD Russian patent published in 2008 - IPC C09D183/04 C09D5/18 

FIELD: chemistry.

SUBSTANCE: invention relates to compositions for flame resistant coating production on wood, especially coloured coatings that shift wood to the hard-flammable material group. The composition for flame resistant coating of wood is described. It contains 8.5-28.0% weight ratio of polyorganosiloxane, 4.0-25.0% weight ratio of a pigment, 2.0-15.0% weight ratio of the filler - muscovite, 2.0-5.0 % weight ratio of trischlorinepropylphosphate as a plasticiser, 0.8-3.0% weight ratio of the rheological additive - bentonite clay and organic solvent, additionally the composition has 4.0-15.0 % weight ratio of alkyd lacquer PF-60 and/or propenoic copolymer BMK-5 which are used as a repining modifier, 10.0-40.0 % weight ratio of ammonium polyphosphate and/or the aluminosilicate filling agent as a flame retarder, organic solvent. At the same time the composition contains polymethylphenylsiloxane laquer "КО-075" or polyphenylsiloxane resin 139-297 as polyorganosiloxane, dolomite or diatomaceous silica or micronised calcspar or zirconium dioxide or micronised agilite or its blend with at least one of them as a filling agent, as a pigment it contains titanium dioxide or chrome oxide or iron - manganese, blended oxide or red ferric oxide, as an organic solvent - xylene or solvent naphtha or propanone or butyl acetate or its mixture.

EFFECT: coatings prepared on the basis of such composition have flame retardant properties and high resistance to proportional action of water.
