[目的]采用双酚A环氧树脂和改性胺固化剂为基体材料，辅以玻璃鳞片等无机填料，开发出了可在潮湿表面及水下施工固化的涂料。[方法]通过圆柱弯曲试验、铅笔硬度试验、抗冲击试验及附着力试验，考察了涂层的力学性能。通过电化学阻抗谱和中性盐雾试验，分析了该涂料在水下固化环境中对钢铁基材的防护性能。[结果]涂布在316钢板上的涂层样品于水下固化后的拉拔附着力可达4.64 MPa，在3.5%NaCl溶液中浸泡100 d后其低频阻抗模值与浸泡初期仍保持在同一数量级，中性盐雾腐蚀3 000 h后涂层表面无起泡、生锈现象，拉拔附着力为1.89 MPa，划痕腐蚀宽度为9.05 mm。[结论]本研究制备的涂料具有优异的防腐性能，可以有效修复海工装备，延长其服役寿命。
