Abstract: In this paper，the ship sailing condition was simulated by the dynamic seawater simulation device，and the dynamic changes of coating surface physical characteristics was studied by periodically testing the changes of the parameters（thickness，surface roughness， 
surface morphology，polishing rate）related to the antifouling performance of the silyl ester acrylate based coating with time. The resistance to fresh water immersion and atmospheric exposure，as well as the real-sea static immersion of the coating were tested. The experimental results showed that the antifouling coating had excellent resistance to atmospheric exposure and fresh water immersion，and the antifouling period could reach 60 months according to theraft testing in the North Sea，which could meet the long-term antifouling requirements ofunderwater facilities. The low-cost and rapid evaluation of antifouling performance could beachieved by combing the dynamic simulation and static immersion test. This method could notonly be used to evaluate the antifouling performance，but also to screen and improve coating formulations，accelerating the development of antifouling coatings.

Key words: silyl ester acrylate, antifouling coating, dynamic performance, polishing rate, fresh water immersion

摘要： 借助动态海水模拟装置模拟船舶航行的服役状况，通过定期测试丙烯酸硅酯防污涂层防污性能参数（厚度、表面粗糙度、表面形貌、抛光速率）随时间的变化规律，研究涂层表面物理特性的动态变化，并对丙烯酸硅酯防污涂层进行了耐淡水浸泡、室外曝晒以及实海挂板防污性能测试。结果表明：该防污涂层具有优异的耐室外曝晒和耐淡水浸泡性能，北海挂板防污期效达到 60个月，可满足水下设施对长效防污涂层的防污需求。动态模拟实验技术与防污涂层实海挂板相结合可实现涂层防污性能的低成本、快速评价。该方法不仅可以用于评估防污涂料的防污性能，而且还可用于涂料配方的筛选和改进，加快海洋防污涂料的研发步伐。
