摘要
为了研制一种适用于海洋钢结构大气区使用的立面反光防腐涂层,以丙烯酸聚氨酯为主要成膜物质,以TiO_(2)添加量为变量,制备了多种丙烯酸聚氨酯漆。通过对丙烯酸聚氨酯漆附着力、对比率的测试,以及其与环氧富锌底漆、环氧云铁中间漆、雨夜反光玻璃微珠组合成配套防腐层的耐盐雾性、耐人工气候老化性进行的研究,最终确定了TiO_(2)最佳质量分数,得到了一种具有较高逆反射亮度系数的新型防腐涂层。结果表明:适当提高TiO_(2)添加比例,可以提升丙烯酸聚氨酯漆力学性能和遮盖性能,但添加比例不宜过大,特别是对于配套防腐层体系而言,TiO_(2)添加比例过大,会对涂层整体性能产生不利影响。
In order to develop a reflective anti-corrosion coating for marine steel structures in oceanic atmospheric zone,acrylic polyurethane was used as the main film-forming material,by adding different proportions of titanium dioxide,a variety of acrylic polyurethane paints were prepared.By testing the adhesion and contrast rate of acrylic polyurethane paint film,the salt spray resistance and artificial weathering resistance of the anti-corrosion layer combined with epoxy zinc rich primer,epoxy micaceous iron oxide intermediate coatings,acrylic polyurethane paints,and rain night reflective glass microbeads were studied,the optimal mass fraction of TiO_(2) was determined,a new anticorrosion coating with high reverse reflection brightness coefficient was obtained.The results showed that the mechanical and covering properties of acrylic polyurethane paint could be improved by increasing the mass fraction of TiO_(2),but the additive amount of TiO_(2) should not be too much,especially for the anticorrosion coating system,that will make some adverse effect on the overall performance of the coating.
