摘要
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
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 TiO 2 in Alkyd coatings.Distribution of particle size was characterized by laser particle sizer.The situation of dispersion of nano-TiO 2 in coatings was observed by TEM.Wear resistance of coatings with different amount of nano-sized TiO 2 was also studied.The results indicated that wear resistance of coatings with 4mass% nano-TiO 2 was superior to the others including the coating with 4mass% of normal sized TiO 2.
