适用于海洋钢结构深水区使用的一种反光防腐涂层的制备与表征

Preparation and Characterization of a Reflective Anti-corrosion Coating for Marine Steel Structures in Abyssal Region

为研制一种适用于海洋钢结构海水全浸区使用的反光防腐涂层,以环氧树脂为主要成膜物质,通过添加不同比例的二氧化钛,制备了多种环氧树脂漆,通过附着力、对比率、光泽、接触角性能的变化,对环氧树脂漆的力学性能、遮盖能力、表面抗污性能进行了表征,确定了二氧化钛最佳添加量后,通过面撒雨夜型反光玻璃微珠,得到了一种在潮湿状态下具有较高逆反射系数的新型防腐涂层。结果表明:适当添加二氧化钛,可以提升环氧树脂漆部分物理性能,增大防腐涂层的反光能力。

In order to develop a reflective anti-corrosion coating for marine steel structure in seawater full immersion zone,with epoxy resin as the main film-forming material,by adding different proportions of titanium dioxide,a variety of epoxy paints were prepared,the mechanical properties,covering capacity and stain resistance of the epoxy paint were characterized by the changes of adhesion,contrast ratio,gloss,and contact angle properties.After determining the optimum amount of titanium dioxide,a new anti-corrosion coating with high coefficient of retroreflection in wet state was obtained by spraying rain-night reflective glass beads on the surface.The results showed that the proper addition of titanium dioxide could improve some physical properties of epoxy paint and increase the reflective ability of anti-corrosion coating.
