摘　　要：以水性聚氨酯为基料,加入颜填料和助剂合成水性防腐蚀涂料。改变涂料配方中颜填料和基料的质量比(P/B),在不锈钢板上制得涂层样品,通过极化曲线和电化学阻抗测试,讨论P/B对涂层腐蚀性能的影响,试验结果表明,涂料配方中P/B=0.8和1.5时涂层综合性能较好。A waterborne anticorrosive coating has been synthesized by using waterborne polyurethane, pigment and stuffing. The pigment/binder ratio （P/B） of the coating was changed. The corrosion resistance properties of polyurethane paints were investigated by corrosion potential measurements and electrochemical impedance spectroscopy （EIS）. The optimum anticorrosive protection was achieved by the coatings with P/B=0.8 and 1.5.
