THERMOREGULATING COATING OF "SOLLAR REFLECTOR" TYPE Russian patent published in 2008 - IPC B64G1/58 C09D5/33 C09D4/00 C09D133/12 

FIELD: transportation.

SUBSTANCE: proposed coating includes a lower layer of an aluminum alloy anodic oxide coating and an upper layer representing a thermo regulating paint coat comprising acrylate holmium-containing vanish "АКГ-1,2" (42-38 percent by weight) and oxide-modified zirconium (IV), 7-4 (58-62 percent by weight). The coating features low solar radiation absorption factor values (A_s ≤ 0,10-0,11) and high radiation factors (ε≥0,92-0,94). This allows reducing the radiator-emitter area which is particularly important in development of promising spacecrafts. Availability of two thermoregulating coatings, i.e. the anodic oxide and paint coatings allows a notable increase in service life of the said radiators and producing the said coatings on the surface of products made from aluminum or its alloys with lower A_s/ε parameter values and without drawbacks inherent in silicate coatings.

EFFECT: antirust protection of complicated-design structures and provision of preset thermal-and-radiation characteristics.
