【摘要】 航天技术的发展和深空探测的需要，对热控涂层的光热性能和空间环境稳定性提出了更加苛刻的要求。为此，文章设计内核为Zn₂SiO₄、外壳为具有可见光波段高透过性SiO₂的核壳结构颜料，并将其制备成热控涂层。试验结果表明：涂层T-Zn₂SiO₄@SiO₂的太阳吸收比为0.09,具有超低吸收特性。在此基础上，文章系统性表征了涂层在真空-紫外辐照后太阳吸收比和内部缺陷的变化，初步解析了紫外辐照后光学性能演化机理，可为研制低太阳吸收比、高稳定性新型热控材料提供新思路。更多还原

【Abstract】 The development of space technology and the needs for deep space exploration have put forward 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 systematically 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.更多还原
