摘要
目的得到一种可以媲美传统含铜防污涂料防污效果的涂料配方,且具有对海洋环境友好的特点。方法首先筛选符合无铜涂料技术需求的环保型防污剂,并进行涂料配方研究,得到最优环保无铜防污涂料配方。结果设计开发的2组不同防污剂复配无铜自抛光防污涂料,其实际防污效果可以达到中期效防污涂料的评价标准,在实际防污效果上可以媲美3年期效以Cu2O为主防污剂的传统含铜自抛光防污涂料。2组防污剂复配配方为Econea/Dcoit及Econea/Zn PT,采用上述2种防污剂进行质量比1:1的防污剂复配,具有1+1>2的实际防污效果,并且在具有较好实际防污效果的同时,具备可以在海水中实现快速降解的优异环境友好性。在无铜涂料配方体系下,中期效防污涂料(3年)中丙烯酸锌树脂的最佳配方含量为40%~50%(湿重)。结论环保无铜防污涂料的各项性能良好,具有广谱、高效的防污效果。
This work aims to obtain a marine environment-friendly copper-free antifouling paint formula which rivals traditional copper antifouling paint. Environment-friendly antifoulant conforming to the technical demand of copper-free paint was selected firstly, coating formula was studied to obtain the optimal formula of environment-friendly copper-free antifouling paint. The two different antifoulants compounding copper-free self-polishing antifouling paint meet the evaluation standard of mid-potency antifouling paint, and can rival the 3 years potency traditional copper antifouling paint. Formula of the two groups is Econea/Dcoit and Econea/Zn PT, respectively. For the antifoulant being compounded by the 2 antifoulants with mass ratio of 1：1, the practical antifouling effect is 1＋12. These two antifoulants have good practical anti-fouling effect and exhibit excellent environmental friendliness as they can degrade rapidly in seawater. The optimum formula content of acrylic zinc resin is 40%~50%（wet weight） in mid-potency antifouling paint in the copper-free antifouling paint formulation system. Various properties of the environment-friendly copper-free antifouling paint were good. The paint had broad spectrum, high efficiency andexcellent antifouling effect.
