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TiO_2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TiO_2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TiO_2的分散状态.同时比较了含有不同含量TiO_2(mass%)及含有普通钛白粉的涂层耐磨性,结果表明,有4%的纳米TiO_2涂层耐磨性最好. |

Dispersion of pigments in coatings is a very important matter for the preparation of coat?ings of good quality. A kind of nonionic surface active agent was selected as a dispersant for TiQj in Alkyd coatings. Distribution 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 TiOa was also studied. The results indicated that wear resistance of coatirigs with 4mass% nano - TiOa was superior to the others including the coating with 4mass% of normal sized TiO2. |
