摘要
通过对水性环氧涂料的研究,深入分析了不同分散剂对水性环氧涂料的稳定性、颜料分散性、防腐性的影响。结果表明,筛选合适的分散剂有利于水性环氧涂料的贮存稳定性,同时也能最大限度地降低分散剂对涂膜性能的影响;在水性环氧面漆中,选择合适的分散剂可使颜料充分展色并防止颜料絮凝,避免浮色、发花等涂膜弊病,使水性涂料涂装后颜色均一。
The influence of different dispersants on the stability,pigment dispersion and anticorrosion of waterborne epoxy coatings is analyzed in depth through research on waterborne epoxy coatings.The results show:screening suitable dispersants is conducive to the storage stability of waterborne epoxy coatings and can minimize the influence of dispersants on the properties of coatings films;selecting suitable dispersants in waterborne epoxy topcoat can realize full color development of pigments,prevent pigment flocculation,avoid film defects such as flooding and floating and make waterborne coatings’color even after painting.
