摘要
以自制含磷苯丙乳液为基料,改性磷酸锌、三聚磷酸铝为防锈颜料,制备出一种环保的水性防锈涂料。考察了乳液、助剂、主要的防锈颜料种类及用量对涂膜性能的影响,当乳液用量为45%(质量分数)左右、PVC用量为35%时,所制水性防锈涂料的耐盐水、耐盐雾时间最长,涂料的综合性能最佳。
The waterborne antirust paint is prepared with self-made phosphate styrene-acrylic emulsion as binder and modified zinc phosphate and aluminum tripolyphosphate as antirust pigment. The effects of sort and content of emulsion, sort and content of additives, sort and content of antirust pigment are investigated. It is found that when styrene-acrylic emulsion is 45% of total mass and PVC is 35%, the coating has the perfect salt-water resistance, salt fog resistance, the comprehensive properties of coating film are the best.
