在普通涂料中加入缓蚀剂构成缓蚀涂料,可以大大增强涂料的防蚀能力。本工作针对舰船船底漆铝扮沥青环氧涂层,研究了二种含有氨基、羧基及杂环的有机缓蚀剂,当在普通的船底漆中加入少量缓蚀剂后,不改变原来涂层的物理机械性能,但可显著地提高涂层的耐蚀性能,采用了浸泡试验、盐雾箱试验及交流阻抗测试对涂层的耐蚀性能进行了评价,并采用电化学方法对涂层缓蚀剂的机理作了探讨。

Adding corrosion inhibitors in common coatings to form corrosion-inhibiting coatings can greatly enhance the anti-corrosion ability of the coatings. In this work, two kinds of organic corrosion inhibitor containing amino, carboxyl and heterocyclic were studied for the coating of ship bottom paint aluminum. When a small amount of corrosion inhibitor was added to ordinary ship primer, the research did not change The original coating physical and mechanical properties, but can significantly improve the corrosion resistance of the coating, the use of immersion test, salt spray box test and AC impedance test of the corrosion resistance of the coating were evaluated and electrochemical methods The mechanism of coating corrosion inhibitor is discussed.
