THERMOREGULATING COATING BASED ON "TRUE ABSORBER" INORGANIC CLASS Russian patent published in 2015 - IPC C09D1/02 C09D5/32 C09D5/24 

FIELD: chemistry.

SUBSTANCE: thermoregulating coating of "true absorber" class is made of composition, including inorganic silicate binding agent and magnetite. Composition contains water lithium silicate solution with modulus 2.9-3.4 (1.0 wt.p.) as inorganic silicate binding agent, magnetite (2.9-4.0 wt.p.) and Co₃O₄ (2.9-4.0 wt.p.), BaAl₂O₄ (0.1-0.8 wt.p.) as pigments and filling agents and water - to required viscosity. Invention is aimed at elaboration of thermoregulating coating of "true absorber" class with improved thermal radiation coefficient ε=0.95, specific volumetric electric resistance ρ_v<10³ Ohm·m.

EFFECT: obtaining technological coating with high coefficient of sun radiation absorption, low gas release by GOST R 50109, resistant to CSF at long terms of active spacecraft existence.
