摘要/Abstract

摘要： 以氨基环氧树脂为基体树脂,Co²⁺、Pb²⁺盐为催干剂合成了阴极电泳漆,并对膜性能进行考察。结果表明,所合成的阴极电泳涂料在pH值为6～7、电泳时间2min的条件下。加入不同的催干剂,在不同的烘干温度下,得到性能不同的漆膜。经过漆膜综合性能试验,结果表明加入钴和铅复合催干剂,在160℃左右烘干20min,可得到完全固化、硬度较高、耐潮、耐盐、耐酸碱性较好的漆膜。

Abstract: Cathodic electrodeposition paint (CEP) was synthesized with amino epoxy resin, and the properties of the paint film was investigated. The results showed that properties of the paint film varied with various catalytic curing agent under the condition of electrodeposition for 2 min at pH 6～7. By comparing properties of the paint film, the superior paint film was obtained from the cathodic electrodeposition coating materials by mixing cobalt and lead salts as catalytic curing agent under the condition of oven-curing for 20 min at 160℃ to form completely cured film of high hardness with good resistances against water, acid, alkali and salt.

Key words: catalytic curing agent, amino-epoxy resin, paint film, cathodic electrodeposition paint (CEP)
