铁路货车用水性厚浆底面合一涂料的制备及其性能研究

Preparation of Waterborne Mastic Primer-topcoat Coatings for Railway Freight Cars and Their Properties

以改性水性树脂为主要成膜物,通过添加高性能环境友好型防锈颜料、有机缓蚀剂和其他功能性助剂,制备了一种水性厚浆底面合一涂料。探讨了防锈颜料、有机缓蚀剂和其他功能性助剂对涂料及涂膜性能的影响。结果表明:实验制备的水性厚浆底面合一涂料防腐性能优异、机械性能良好、干燥快、易施工,可满足铁路货车的涂装要求。

A kind of waterborne mastic primer-topcoat coatings was prepared with modified waterborne resin as the main filmforming material, high-performance environmentally friendly anti-rust pigments, organic corrosion inhibitors and other functional additives. The effects of anti-rust pigments, organic corrosion inhibitors and other functional additives on coatings and the properties of coatings film were discussed. The results indicated that the waterborne mastic primer-topcoat coatings prepared in the experiment had excellent corrosion resistance and good mechanical properties. In addition, the fast-drying and easy-to-apply coatings could meet the requirements of railway freight cars.
