【摘要】 利用树脂上的亲水基团在常温下能够与有机成盐剂形成有机盐,使树脂具备良好的水溶性。而在高温烘烤条件下,成盐剂能够较快的挥发,同时树脂上某些特定基团能够与亲水基团作用,使成膜固化后的树脂几乎不含亲水基。在其他添加剂的共同作用下,最终漆膜呈现出憎水性。实验结果表明,该水性涂料具有抗高温碱性水腐蚀性能。更多还原

【Abstract】 The aqueous paint which has unique hydrophilic groups on its molecular chain was discussed. At ambient temperature, these groups can form polymer salts with salifying reagent, make the resin well dissolved in water based system. At high temperature, unique groups can react with some different groups on the molecular chain of the resin. After roast process, all hydrophilic groups can be removed. The final coating has good anti-water performance. The results show that the service life of aqueous paint is long in hot alkali water environment.更多还原
