摘　　要：以磷酸锌为主要防锈颜料,协同云母氧化铁灰,制备了无溶剂型环氧防腐涂料,对涂层基本性能进行了测试,并利用交流阻抗(EIS)测试技术和中性盐雾试验研究防锈颜料质量比对涂层防腐性能的影响。结果表明:当PVC为8%,云铁灰与磷酸锌质量比为1∶4左右时,涂层具有较好的防腐性能和耐划伤性能。Solventless epoxy anticorrosion coatings was prepared with zinc phosphate, together with micaeeous iron oxide gray as the main antirust pigments. The effects of the mass ratio of antirust pigment on the corrosion resistance of coating were studied through EIS and the salt spray test. The results showed that when the PVC was 8% , and the mass ratio of zinc phosphate to micaceous iron oxide gray was about 1 ： 4, the coatings exhibited good performance of corrosion resistance and scratch resistance.
