RAW MATERIAL MIXTURE FOR THE MANUFACTURE OF HEAT-INSULATING POLYMER COMPOSITE MATERIALS Russian patent published in 2022 - IPC C08L25/06 C08K3/13 C08K5/02 

Abstract RU 2772611 C1

FIELD: composite materials.

SUBSTANCE: invention can be used for the manufacture of heat-insulating panels. The raw material mixture for the manufacture of heat-insulating polymer composite materials includes a filler, polystyrene foam waste and technical methylene chloride. Crushed wood ash is used as the filler. The ratio of polystyrene foam waste to methylene chloride ranges from 1:1.5 to 1:2.

EFFECT: increase in the strength and reduction in water absorption of heat-insulating composite materials obtained from the raw material mixture.
