摘要
Abstract
The development of space technology and the needs for deep space exploration have put for-ward more stringent requirements on the photothermal performance and space environment stability of paint-based thermal control coatings.For this reason,the core-shell structure pigment with Zn2SiO4 as the inner core and SiO2 as the outer shell with high transmittance in visible wavelength are designed,and it is prepared as a thermal control coating.The test results indicate that the solar absorption ratio of coa-ting T-Zn2SiO4@SiO2 is 0.09,which has ultra-low absorption characteristics.On this basis,the changes in solar absorption ratio and internal defects of the coating after vacuum-ultraviolet irradiation are sys-tematically characterized,and the evolution mechanism of optical properties after ultraviolet irradiation is preliminarily analyzed,which can provide a new idea for the development of a new type of thermal control material with low solar absorption ratio and high stability.关键词
