 在制备涂料中，颜料的分散是非常重要的，本文选择了一种非离子型的表面活性剂作为纳米TiO2在醇酸涂料中的分散剂，用激光粒度仪得到了涂料体系中的TiO2的粒度分布曲线.并结合TEM照片观察到了在有分散剂和没有分散剂时，纳米粉TiO2的分散状态.同时比较了含有不同含量TiO2(mass%)及含有普通钛白粉的涂层耐磨性，结果表明，有4%的纳米TiO2涂层耐磨性最好.  

Dispersion of pigments in coatings is a very important matter for the preparation of coatings of good quality.A kind of nonionic surface active agent was selected as a dispersant for TiO2 in Alkyd coatings.Dist ribution of particle size was characterized by laser particle sizer.The situation of dispersion of nano-TiO2 in coatings was observed by TEM.Wear resistance of coatings with different amount of nano-sized TiO2 was also studied.The results indicated that wear resistance of coatings with 4mass% nano-TiO2 was superior to the others including the coating with 4mass% of normal sized TiO2.
