HEAT-INSULATING PAINT-COATING BASED ON THE FRIED DIATOMITE Russian patent published in 2017 - IPC C09D133/00 C09D5/02 

FIELD: chemistry.

SUBSTANCE: heat-insulating coating paint contains an aqueous emulsion of acrylic copolymer "Akremos-101", an aqueous solution of acrylic copolymer "Akramos-401", diethylene glycol, sodium polyphosphate, white spirit, sodium borosilicate glass microspheres with a crush resistance of at least 30 bar, Mineral fillers - white soot and fired for 5 hours at a temperature of 550°C diatomite, water, for a given ratio of components.

EFFECT: invention meets the requirements of heat conductivity while ensuring conditions of use in microspheres based on sodium borosilicate glass with resistance to crushing of at least 30 bar, which allows to avoid destruction during mixing of the microspheres and to provide the required thermal insulation characteristics.
