摘　　要：采用盐雾试验、电化学阻抗法和辉光光谱法对三种环保型家电镀锌板表面的涂层进行研究,发现涂层的结构和涂层中缓蚀剂的分布对涂层表面性能有较大影响,提高涂层中Si和缓蚀剂的含量,保持缓蚀剂分布均匀可以有效提高镀锌板的表面性能。表面涂层中有机高聚合物含量较多时,高温下容易发生氧化变色。The surface performance of three kinds o{ environment-friendly galvanized sheets was studied by salt spray test, eletrochemical impedance spectroscopy （EIS） and glow discharge spectrometer （GDS）. The results showed that the coating performance was greatly influenced by the structure and distribution of inhibitor on the suface of film. Surface performance could be enhanced by increasing the content of inhibitor and Si, and by keeping umform inhibitor distribution. It would be oxidated when the surface of film contained more organic polymer.
