HEAT INSULATING PAINT COAT Russian patent published in 2015 - IPC C09D133/00 C09D135/06 C09D5/02 C09D5/08 

FIELD: chemistry.

SUBSTANCE: heat insulating paint coat contains a film-forming agent in the form of an aqueous emulsion of a copolymer of styrene and acrylic monomers Akremos-101, a thickener in the form of an aqueous emulsion of a copolymer Akremos-401, a dispersant in the form of sodium polyphosphate, an antifreeze agent in the form of diethylene glycol, a coalescing additive in the form of white spirit, mineral filler and water; the paint further contains glass microspheres based on sodium borosilicate glass, wherein the mineral filler is diatomite and white soot, with the following ratio of components, wt %: aqueous emulsion of a copolymer of styrene and acrylic monomers Akremos-101 17.5-22.46, aqueous solution of an acrylic copolymer Akremos-401 4.28-5.46, diethylene glycol 10.27-13.10, sodium polyphosphate 3.85-4.91, white spirit 2.57-3.27, diatomite 6.06-13.63, white soot 3.06-5.12, microspheres based on sodium borosilicate glass 6.06-7.50, water - the balance.

EFFECT: heat insulating paint coat has low heat conductivity and density while providing sufficient adhesive strength of the coating.
