摘要:

采用物理混合的方法在Q235碳钢表面制备一种环氧树脂基导电复合涂层。结果表明, E51环氧树脂清漆涂层存在大量的微泡, 严重影响涂层的防护性能。导电复合涂层的微泡数量显著降低, 经2000 h盐水浸泡和盐雾腐蚀实验结果表明, 涂层未出现起泡、剥落等破坏, 涂层下的Q235碳钢未发生腐蚀。电化学交流阻抗表明, 随着浸泡时间的延长E51清漆涂层的阻抗急剧降低, 而复合涂层的阻抗随着浸泡时间的延长而增大, 表现出一定的自修复功能。复合涂层的电阻率和附着力分别为10³ Ωcm数量级和9.12 MPa。

Abstract：

Conductive epoxy resin based composite coatings were prepared by physical blending process and then applied onto on Q235 carbon steel surface. The results show that there existed lots of micro-blisters in the pure E51 epoxy coating without pigments, which deteriorate the protectiveness of the coatings. In the contrast, the quantity of the micro-blisters of the conductive composite coatings was decreased greatly by adding pigments. The test results of immersion in 3%NaCl solution and salt spray indicated a superior corrosion resistance of the composite coatings. After corrosion test, no bubbling or pickling for the composite coatings could be observed and no corrosion was detected for Q235 carbon steel underneath the coatings. Electrochemical experiments revealed that the impendence of the E51 coating decreased fast, while that of the composite coatings increased with the immersion time in 3.5%NaCl solution. The composite coatings have 'self-healing' ability. The electric resistance and adhesion strength of the composite coatings are in the order of 10³ Ωcm and 9.12 MPa respectively.
