FIELD: special covers.
SUBSTANCE: invention relates to space materials technology and optical technique. Invention describes a composition for the paint and varnish thermoregulating cover of class "solar reflectors" comprising pigment zirconium (IX) oxide modified with aqueous silicic acid of special purity in the amount 48-52 wt.-% and acrylate lacquer holmium-containing AKG-1,2 as a binding agent representing polyethylmethacrylic resin solution in mixture of organic solvents and modified with holmium triacetylacetonate and taken in the amount 52-48 wt.-%. Proposed composition possesses the enhanced radiation resistance that allows its using in space devices exploiting on high orbits. Invention can be used in systems for passive thermoregulation of space devices.
EFFECT: improved and valuable technical properties of composition.
