环氧防水涂料固化剂酮亚胺合成方法及性能

摘要

Curing agent has an important role on property of the epoxy resin waterproof coating. A new kind of curing agent ketimine synthesized.The experimental results show different reac-tion conditions influence the curing agent synthetic reaction conversion rate.When the addition ratio of MIBK ∶MXDA was 3 ∶ 1,with 130 ℃ reaction temperature,and 3.5 h of reaction time,the reaction conversion rate was the best.%环氧树脂防水涂料的性能与固化剂有着很大的关系.本文作者合成出一种酮亚胺固化剂,通过实验考察了影响其产率的因素,并与其他三种常用的固化剂在性能上进行了比较.结果表明,酮亚胺的固化效果优良,当甲基异丁基酮(MIBK)与间苯二甲胺(MXDA)单体投料比为3∶1时,产率较高,最佳的合成反应温度为130℃,反应时间为3.5 h.
