研制了一种用于工程机械的快干型水性环氧底漆,其漆膜表干快,盐雾性能好,厚涂漆膜无流挂等漆膜弊病。通过对不同环氧乳液和水性固化剂进行选型,添加颜料、防锈填料、各种助剂、成膜助溶剂等制得快干型水性环氧底漆。重点考察不同环氧乳液和环氧固化剂及其用量、不同颜基比、不同增稠剂类型和配比对涂料性能和施工的影响,最终研制出综合性能优异的工程机械用快干型水性环氧底漆。

A kind of quick drying waterborne epoxy primer for construction machinery was developed.The coating surface dries quickly,the salt spray performance is good,the thick coating has no flow hanging and other coating defects.Waterborne epoxy primer was prepared by using different epoxy emulsions and waterborne amine hardener as base materials,adding pigments,anti-rust fillers,various additives,cosolvent.The influence of different epoxy emulsions and epoxy curing agents and their dosage,different facial base ratios,types and ratios of different thickening agents on the performance of coating and construction were mainly investigated.The waterborne epoxy primer for construction machinery with excellent comprehensive performance was finally developed through experiments.
