FIELD: manufacture of building materials on base of polymer compositions; structural material for heat-insulated plates of poly-functional purpose, wall panels for example.
SUBSTANCE: proposed heat-insulating composition contains 70-90 mass-% of polyurethane and 10-30 mass-% of filler; used as filler are sol micro-spheres of combustion products of solid slag disposal with size of particles of 1-10 mcm, no more than 20 mass-%, with size of particles of 30-40 mcm, no less than 65 mass-% and with size of particles of 80-100 mcm, no more than 15 mass-%. Composition has density of 51 kg/m3, compressive strength of 1.36 Mpa and heat conductivity coefficient of 0.124 W/m*K.
EFFECT: enhanced efficiency.
