摘要
采用甘氨酸和硅烷偶联剂KH-550同时改性环氧树脂,使其成为既具有亲水性又含偶联功能的树脂,并制备了稳定的不同固含量的水性环氧乳液系列。性能测试结果表明,制得的水性环氧树脂在有机溶剂中的溶解性变差,在碱性水溶液中的溶解性增强,作为水性环氧涂料,其固化物具有优良的涂膜性能,特别是与基材的附着力和耐水性得到更明显地改善。
Epoxy resin is modified with glycine and coupling agent KH -550, showing hydrophilic and coupling performance, which is then formulated into stable waterborne epoxy emulsion with various solid contents. The modified resin shows lower solubility in organic solvents than the unmodified resin does, but higher dissolubility in basic solution. The cured film of waterborne epoxy coatings provides excellent performance. Darticularily the adhesion and water resistance by modification are good.
