摘　　要：文章通过对双组份水性环氧防腐底漆的影响因素进行各方面研究,同时对复合涂层进行了测试。实验表明,当环氧乳液与固化剂的比例为4∶1、防锈颜料的添加量为10%、养护温度≥10℃、液体环氧树脂复配添加量为0%、粘度控制在90 ku-100 ku时,水性环氧防腐底漆的耐盐雾性能达到最佳,在与水性聚氨酯进行复合涂层时,各方面性能得到更加明显的体现,且远远优于标准《水性环氧树脂防腐涂料》(HG/T 4759—2014)中的要求。In this paper,the influencing factors of the two-component waterborne epoxy anticorrosive primer are studied in various aspects,and the composite coating is tested at the same time.Experiments show that the ratio of epoxy emulsion to curing agent is 4∶1,the amount of anti-rust pigment added is 10%,the curing temperature is≥10℃,the added amount of liquid epoxy resin compound is 0%,and the viscosity is controlled at 90 ku-100 ku,the salt spray resistance of the water-based epoxy anticorrosive primer reaches the best.When it is combined with water-based polyurethane,all aspects of its performance are more obvious,and it is far better than the standard HG/T 4759-2014.
