摘　　要：介绍了一款新型水性锈转化丙烯酸酯涂料的研制。采用质量比3∶1的单宁酸和磷酸组成转锈剂,当其添加量为6.0%(质量分数)时具有最佳的转锈效果。根据扫描电镜表征、Tafel曲线测量及耐介质测试的结果,分析了涂层的最佳施工条件,并分别与环氧、聚氨酯和有机硅面漆进行配套。该锈转化涂料完全可以替代传统涂料施工前基材手工打磨的预处理方式。The preparation of a novel waterborne acrylate-based rust conversion paint was introduced.The best rust conversion effect could be obtained by addition of 6%(mass fraction)of a rust converter composed of tannic acid and phosphoric acid at a mass ratio of 3:1.The conditions for application of the paint were optimized by scanning electron microscopic characterization,Tafel curve measurement,and medium resistance testing.The compatibility of the paint with different topcoats were examined.The paint can be used for replacing the manual grinding as pretreatment of substrate.
