| 摘 要： | 将不同比例的装载缓蚀剂蒙脱土和环氧树脂混合制备出纳米复合环氧涂层。根据电化学阻抗谱 (EIS) 和盐雾实验对涂层的耐蚀性进行表征。结果表明,3%装载蒙脱土环氧涂层的水扩散系数为9.89×10-11 cm2/s,孔隙率为2.22×10-8,整个浸泡过程中阻抗值在109 Ωcm2以上,表现出最佳的耐蚀性。

| Abstract: | Nanocomposite epoxy coatings were prepared with different proportion of epoxy resin and inhibitor-grafted montmorillonite. The effect of the inhibitor-grafted montmorillonite on the corrosion resistance of epoxy coating on hot dip galvanized steel sheet was investigated by using salt spray tests and electrochemical impedance spectroscopy (EIS). The results show that among the coatings tested, the one with 3% of the inhibitor-grafted MMT exhibits the most superior corrosion resistance with water diffusion coefficient of 9.89×10-11 cm2/s and porosity of 2.22×10-8 respectively; while its impedance values is above 109 Ωcm2 during the whole immersion times. |
