摘　　要：以水性丙烯酸树脂作为成膜物质，将球状锌粉和片状锌粉进行复配，制备出一种耐腐蚀性良好的水性有机富锌底漆。对影响富锌底漆耐腐蚀性能的主要因素进行分析，结果表明：以乳液A作为成膜物质、球状锌粉2^#（800目）与片状锌粉Ⅰ的配比为3：2、颜填料b用量为6％、PVC为50％～55％时，产品的综合性能最佳。A kind of waterborne anti - corrosive organic zinc - rich primer is formulated, with waterborne acrylic resin as the main film -former, compounded with spherical zinc and flake zinc powders. The factors which had influences on the anti - corrosive performance of zinc - rich primer were analyzed. The results showed that when emulsion A as the main film -former, spherical zinc 2^#（800 mesh） with the ratio of flake zinc I as 3：2, pigment 6% and PVC 50% -55% ,the comprehensive performances is the best.
