摘要/Abstract

摘要： 长期以来,低吸收辐射比有机温控涂层是人们着重研究的一类重要的卫星被动温控涂层,这类涂层应具有低的太阳吸收率α_s,以及高的热辐射率ε_n,即涂层必须有低α_s/ε_n值。而旦,涂层在宇宙环境中应保持该性能的长期稳定性。本文概述固外低α_s/ε_有机温控涂层的研制情况。

Abstract: Several topics were reviewed in this article. Most organic coatings are subjected to degredation by ultraviolet radiation, soc the preparation of UV-resisting polymer binder of coating provides the greatest technical challenge. the more similar to quartz structure silicone resin, the more stable to UV the sillicone binderis. It has shown that the monomethylsilicone resin OI-650G is the most stable binder. The UV-resistance propety and effectivess in protecting the polymer binder from UV by pigments are concerned with the properties of the coating deeply. So for, both potassium silicate-treated ZnO and Zn_2TiO_4 are the most suitable pigments, and the coatings with low α_s/ε_n made from each of that two pigments with silicone resin OI-650G respectively are the satisfiable exterior organic temperature control coatings for the satellite.
