Abstract

The invention provides an optical solar reflector thermal-control coating on the satellite solar panel surface and a preparation method of the coating. The coating comprises the following components:an optical solar reflector, a conductive adhesive and a surface treatment agent, wherein the conductive adhesive is an adhesive formed by mixing an A component, a B component and silver powder according to a predetermined ratio, and the surface treatment agent includes a KH550 silane coupling agent. The coating provided by the invention has better coating electrical conductivity on the basis thatgood thermal control performance (solar absorption ratio and hemispherical emissivity) of the coating is ensured, and the coating has very good adhesion after subjected to surface treatment.

Description

technical field [0001] The invention relates to the technical field of aircraft thermal control materials, in particular to a thermal control coating for a glass-type secondary surface mirror on the surface of a satellite solar substrate and a preparation method thereof. Background technique [0002] Anti-static cerium glass silver-plated secondary surface mirror, also known as optical solar reflector, or "OSR" for short, is one of the most ideal thermal control materials for long-life satellites. OSR is pasted on the outer surface of the satellite to effectively control the surface of the satellite. temperature, to ensure the normal operation of the instruments and equipment on the spacecraft, and to ensure that the spacecraft can complete the specified tasks during the design life. Anti-static cerium glass silver-plated secondary surface mirror is used as a special thermal control material in the thermal control field of spacecraft. Therefore, it is more and more widely u...
