温控白漆原子氧、紫外综合环境效应退化影响初步研究

文章主要介绍了对 S781、SR107-ZK 两种国产温控白漆进行地面单一原子氧环境、原子氧/紫外综合环境效应模拟试验的情况.试验条件为短期环境暴露试验,原子氧积分通量、紫外辐照积分量按照STS-8轨道条件设计。采用 SEM、XPS,光谱计、微量天平等对试验前后的样品进行了表面形貌、表面成分、太阳吸收率、质损分析,对这两种国产温控白漆原子氧、紫外环境效应退化规律有了初步认识。

PRELIMINARY RESEARCH ON DEGRADATION OF THE THERMAL CONTROL PAINTS IN AO/UV ENVIRIONMENT

Some experiments of AO effects and AO/UV synergistic effects on two thermal control paints,S781 and SR107-ZK,have been completed at the Beijing Institute of Spacecraft Environment Engineering.The test samples were exposed to the simulated space environment,same as STS-8,for short duration.The morphology,mass loss,solar absorptivity and composition of specimens were analyzed by SEM,microbalance,spectrophotometer,and XPS before and after exposure. The degradation of the two paints has been investigated prelimilarily.
