海洋工程应用水下涂装防污涂料的研究

Research on Underwater Antifouling Coating for Marine Engineering

将叠氮基团接枝到环氧树脂上以提高环氧树脂的湿态附着强度,然后将其与环氧树脂618按不同比例复配制备成水下涂装防污涂料,并对涂料的附着强度、铜离子渗出率及海洋防污性能进行研究。研究表明,随着叠氮化环氧树脂用量的增加,水下防污涂层的附着强度先升高后降低;铜离子渗透出率测定和实海浸泡表明该水下涂装防污涂料具有一定的防污性能。

Azide groups were grafted onto the epoxy resin to improve the wet adhesion strength of the epoxy resin,then the modified epoxy resin was compounded with the epoxy resin 618 in various proportions to prepare underwater antifouling coatings. The adhesion strength,copper ion leakage ratio and marine antifouling performance of the underwater antifouling coatings were investigated. Results showed that the underwater adhesion strength increased first and then decreased with the increase of azide epoxy resin. The copper ion leakage and the submergence showed that the underwater antifouling coatings functioned well in anti-fouling.
