摘　　要：以苯甲酸钠作为海洋污损生物的防污剂,以聚二甲基硅氧烷有机硅树脂作为海洋防附着涂料的基料,并对聚二甲基硅氧烷海洋防附着涂料进行了研究。利用扫描电镜观察添加NaB的PDMS防附着涂层的微观形貌以及测得聚二甲基硅氧烷在加入苯甲酸钠后涂层表面的静态水接触角未发生太大变化,得出结论苯甲酸钠在涂层表面未形成团聚而影响涂层的低表面能特性。采用标准曲线法,通过测定溶液的电导率,根据标准曲线,推算出苯甲酸钠的累计释放量,发现含苯甲酸钠的防附着涂层没有发生"暴释"的现象。采用GB5370-85防污漆样板浅海浸泡试验方法。将防污网片浸泡在浅海中,逐月观察网片上海洋污损生物附着种类、附着量及繁殖程度,同时与空白网片作比较。观察到涂有防附着涂层的网片被附着面积比率与对照组相比明显的降低,防污性能相当优异;而且在涂有防污涂层的网片上,几乎没有藤壶等大型污损生物的附着。Sodium benzoate was used biocide in marine biofouling protection and incorporated into silicone coating. This review investigated the distribution and morphological structure of sodium benzoate in silicone by SEM and the water contact angles essentially maintained around those values after incorporating sodium benzoate up to 2%, suggesting that most sodium benzoate molecules were entrapped inside the bulk of the polymer matrix rather than aggregating on the surface. According with GB5370-85, antifouling nets were hung up between net cases in the test maritime space. Once a month, check on the attachment on antifouling materials and weigh and take pictures. The result of test proved that the antifouling fishnet material has made the satisfactory antifouling result.
