摘要
研究了Ｆｅ２Ｏ３－Ｃｒ２Ｏ３有机硅改性丙烯酸选择性吸收涂层及其与ＴｉＯ２－ＳｉＯ２选择性透过膜复合涂层的性能，讨论了影响涂层光学性能的因素。当黑色颜料用量为４０—５０％、粒径０．０５—０．５μｍ、掺铝箔２０％左右、涂层厚度约２μｍ时，涂层光学性能较佳。该涂层还有较好的力学、耐腐蚀及耐老化等性能。涂敷ＴｉＯ２－ＳｉＯ２薄膜后其光学性能、硬度和耐蚀性等均得到改善。
The coating optical properties, hardness. adhesion and durability of Fe2O3-Gr2O3 selective paint are described. Effects of pigment properties .and coating thickness on the optical properties have been studied. Sol-gel dipping method has been used to prepare TiO2-SiO2 layers on the top of Fe2O3-Cr2O3 coating. The properties of the multilayer is much better than Fe2O3-Cr2O3 coating.
