水性无树脂色浆体系的研究与制备

相对于含树脂的色浆体系,无树脂色浆体系具有通用性强等特点。文章讨论了水性无树脂色浆制备过程中的影响因素,如颜料、分散剂、消泡剂以及流变剂等,其中在制备有机色浆过程中,超分散剂具有分散性好、稳定性强等特点;确定了无机和有机通用色浆的配方。采用高速分散、研磨等工艺,制备出贮存稳定、相容性良好以及环保的水性色浆,通过SEM观察了色浆的分散状态,测试了其基本性能,如细度、耐化学性等。讨论了色浆的评价方法和色浆在涂料中的应用。

Study and Preparation of Waterborne Resin-Free Colorants

In contrast to resin-containing colorants,the resin-free colorants have some advantages of universal application.Some influence factors including pigments,dispersants,defoamer,and rheological agent,etc on preparation of waterborne resin-free colorants were discussed.During preparation of organic colorants,hyper-dispersant showed a good assistance for dispersing and stabilization.The formulas of inorganic and organic colorants were finalized.By use of high speed dispersion and grinding,the environment friend...
