摘　　要：用导电云母替代富锌涂料中的部分锌粉,制备了含不同含量导电云母的抗静电耐腐蚀涂料,涂料经固化形成抗静电耐腐蚀涂层,测试了涂层的力学性能和抗静电性,采用盐雾、浸泡以及电化学等测试方法对涂层耐腐蚀性能进行了评价,并对涂层进行了防腐蚀机理的分析。结果表明:盐雾实验对涂层的抗静电性能影响不大。导电云母添加量为3%时,涂层阴极保护作用提高,并具有最佳的防静电性和防腐蚀性。By replacing partially, the quantity of zinc powder in zinc-rich coatings with conductive mica, zinc-rich coatings with different amount of conductive mica were prepared, then of which the antistatic-, mechanical-and anticorrosion-properties were assessed by means of measurements of surface-and volume-resistivity, pencil-hardness, impact resistance and adhesion etc. as well as immersion test, salt spray test and electrochemical impedance spectroscopy. Results show that the antistatic properties of the coatings are only slightly affected after the salt spray test. Among others, the coating with addition of 3% conductive mica shows the best performance in antistatic and anticorrosion, while the cathodic protection effectiveness of the coating is improved.
