Description

一种水分散型环氧固化剂
技术领域
本发明涉及涂料领域，具体涉及一种水分散型环氧固化剂。
背景技术
随着现代社会的发展，人类生活水平的提高，节能环保意识的逐步觉醒，以及高分子科学的高速发展对于环保的要求也越来越严格。
随着广东省地方标准《集装箱制造业挥发性有机物排放标准》的制定，和国家税务部门对高VOC含量的油漆产品征收消费税；集装箱涂料的全面水性化越来越紧迫。
可以预见未来很长时期内，发展环境友好型水性涂料必将成为我国涂料研究领域的重点、热点，为顺应时代发展要求、实现我司集装箱涂料的全面更新换代与绿色环保目标，我公司开发了集装箱用水性环氧系列油漆。因此拟开展相应原材料——水分散型环氧固化剂的研发。
目前，市售的水性环氧树脂，品种繁多，良莠不齐，相比发展成熟的油性环氧固化剂普遍存在的问题有：亲水的环氧固化剂与疏水的环氧树脂相容性差，造成成膜不良、耐蚀性下降、光泽差、适用期短。针对以上问题，为解决我公司开发的集装箱用水性环氧系列油漆的原料急需，研发水分散型环氧固化剂。
发明内容
本发明所要解决的技术问题是提供一种疏水性环氧固化剂，具有优秀的相容性和储存稳定性，可改善漆膜机械性能，使漆膜具有优秀的附着力、柔韧性、抗冲击能力。
本发明所要解决的技术问题通过以下技术方案予以实现：
一种水分散型环氧固化剂，由以下重量份数组分组成：
三乙烯四胺5-10份；

壬基酚5-10份；
双缩水甘油醚10-20份；
丙二醇甲醚10-20份；
去离子水60-100份。
进一步的，所述的环氧树脂为E51。
本发明具有如下有益效果：
采用壬基酚、双缩水甘油醚、丙二醇甲醚相互搭配，与疏水的环氧树脂相容性好，固化后的漆膜具有优秀的附着力、柔韧性、抗冲击能力。
