水性环氧防腐涂料的制备及性能研究
|
摘要
采用水性环氧树脂和聚酰胺固化剂为主要成膜物质,配以合适的颜填料与助剂,制备了综合性能符合标准要求的水性双组份环氧防腐涂料。发现环氧基与胺氢当量比为1∶0. 8或者1∶0. 7时,漆膜的综合性能良好;选用防闪锈剂C,并磷钼酸锌的使用量不低于6‰时,漆膜防腐性能良好。可以作为环氧底漆或者环氧面漆使用,在钢结构,集装箱,工程机械等领域的防腐具有广阔的应用前景与良好的经济效益。
The waterborne two-component epoxy anticorrosive coating with comprehensive performance conforming to standard requirements were prepared with water-based epoxy resin and polyamide curing agent as the main film-forming materials,as well as appropriate fillers and additives. It was found that when the molar ratio of epoxy group to active hydrogen was 1 ∶ 0. 8 or 1 ∶ 0. 7,the comprehensive performance of the film was fine. The film had good corrosion resistance when antirust agent C was selected,and the amount of zinc phosphomolybdate was not less than 6‰. This coating can be used as epoxy primer or epoxy topcoat. It had broad application prospects and good economic benefits in steel structure,container,construction machinery and other fields.
