Abstract: The title silicone wear resistant coatings was been developed by co-hydrolysis of silane coupling agent (3-glycidyloxypropy1 )trimethoxysilane(KH-560)and titanium butoxide [Ti(OBU)₄] through sol-gel method. The optical and mechanical properties of the hybrid coatings were characterized by various techniques. It has shown that the coatings films have high transparency of above 90% in the range of visible light, and pencil hardness 6H both before and after aging, and good thermal stability and adhesion.

Key words: silicone, sol-gel, wear-resistant coating, hybrid coatings film

摘要： 采用溶胶 －凝胶法，将钛酸酯、正硅酸乙酯和硅烷偶联剂（KH-560）进行共水解，经涂覆、固化，制备了含二氧化钛的耐磨透明膜层材料，通过各种方法对该涂料和膜层的光学和机械性能进行了分析表征。结果表明：所得复合耐磨透明膜层材料在可见光范围内的透过率均在 90%以上，具有较好的耐热性，并且膜层与基材的附着性好，铅笔硬度达到 6H。
