摘要

为制备防腐性能和抗流挂性能优良的水性环氧富锌底漆,以环氧树脂、水性环氧固化剂、固化剂促进剂、锌粉、有机膨润土、气相二氧化硅和聚酰胺蜡等制备了水性环氧富锌底漆。研究了环氧树脂、固化剂促进剂对涂料防腐性能的影响,通过三水平三因素正交试验研究了有机膨润土、气相二氧化硅和聚酰胺蜡用量对水性环氧富锌底漆抗流挂性能的影响。结果表明:采用E51环氧树脂、固化剂促进剂添加量1.0%、聚酰胺蜡添加量0.8%、有机膨润土添加量1.5%、气相二氧化硅添加量0.4%时,各项性能达到了溶剂型环氧富锌涂料的指标。

Abstract

In order to prepare a waterborne epoxy zinc-rich primer with excellent corrosion resistance and sagging resistance,a waterborne epoxy zinc-rich primer was prepared using epoxy resin,waterborne epoxy curing agent and relevant accelerator,zinc powder,organic bentonite,fumed SiO2and polyamide wax.The effects of epoxy resin and waterborne epoxy curing agent accelerator on the corrosion resistance of coating were studied,and the orthogonal test with three factors and three levels was used to analyze the influences of different dosages of organic bentonite,fumed SiO2and polyamide wax on the sagging resistance of the waterborne epoxy zinc-rich primer.Results showed that when E51 epoxy resin was used,the curing agent accelerator was 1%,polyamide wax was 0.8%,organic bentonite was 1.5%,and fumed SiO2was 0.4%,all performance index met the requirements for solvent zinc-rich primer.

Key words： waterborne epoxy zinc-rich primer; sagging resistance; corrosion resistance; preparation
