针对传统热控涂层在紫外波段的高吸收现象，以铈酸钇、纳米氧化锌和介孔材料 SBA-15为原料，通过高温烧结的方式制备出高紫外反射型热控颜料，将其分别与无机粘结剂硅酸钾或有机粘结剂环氧改性有机硅树脂相结合制备成低吸辐比（ αs/ε）热控涂层。结果表明： ZnO/SBA-15与硅酸钾制得的热控涂层紫外波段反射率超过 0.90，吸辐比小于 0.08。对颜料及热控涂层的微观形貌、光学性能和耐候性能研究表明，该类热控涂层具有优异的光学性能和较强的环境适应能力。
In this paper，regarding the problem of high absorption in ultraviolet band of traditional thermal control coatings，Y2Ce2O7，nano-ZnO and SBA-15 were used as raw materials to prepare the thermal control pigments with high ultraviolet reflectivity by high temperature sintering，which was then mixed with inorganic binder potassium silicate or organic binder epoxy-modified silicone resin to form thermal control coatings with low absorptivity/emissivity ratio（αs/ε）， especially the coatings with ZnO/SBA-15 and potassium silicate showed reflectivity above 0.90 in UV band and αs/ε below 0.08. The microstructure，optical properties and weatherability of the pigments and thermal control coatings were
studied. The results showed that the thermal control coatings provided excellent optical properties and high environmental adaptability.
