Abstract The damage caused by marine fouling organisms to ships and underwater artificial equipment is becoming increasingly serious issue, and the prevention and control of marine biofouling has always been a research hotspot in marine coatings. Aiming at the problems of poor adhesion, long curing time and high curing temperature of low-surface energy marine antifouling coatings of organosilicon, a hydrophobic low-surface energy nano-SiO2/silicon acrylic resin nanocomposite coating was synthesized. The anticorrosive property of the composite coatings was analyzed by simulated seawater periodic immersion experiments. The gel permeation chromatography analysis showed that polydimethyl-siloxanes (PDMS) is involved in cross-linking reactions. The dynamic thermomechanical analysis indicated that the glass transition temperature of resin is 58 °C. The contact angle (CA) test showed that the CA of nanocomposite coating is 109.99°. All the detection results can support the excellent antifouling and anticorrosion performance of the low surface energy nanocomposite coatings.

含有二氧化硅纳米粒子的硅丙烯酸树脂作为海水中防污和防腐性能的候选材料的表征

摘要 海洋污损生物对船舶和水下人工设备造成的损害日益严重,海洋生物污损的防治一直是船舶涂料的研究热点。针对有机硅低表面能海洋防污涂料附着力差、固化时间长、固化温度高等问题,合成了一种疏水性低表面能纳米SiO2/硅丙烯酸树脂纳米复合涂料。通过模拟海水周期性浸泡实验分析了复合涂层的防腐性能。凝胶渗透色谱分析表明聚二甲基硅氧烷 (PDMS) 参与了交联反应。动态热机械分析表明树脂的玻璃化转变温度为58℃。接触角(CA)测试表明纳米复合涂层的接触角为109.99°。所有检测结果都可以支持低表面能纳米复合涂层优异的防污和防腐性能。
