Description

一种水性环氧乳液的制备方法
技术领域
本发明涉及一种水性环氧乳液的制备方法,属于功能高分子材料领域。
背景技术
环氧树脂因其优异的附着力、机械强度、稳定性、耐化学腐蚀性、绝缘性等特性,广泛地应用在粘合剂、涂料、电子灌封材料、复合材料基体等领域。
传统的环氧树脂都是溶剂型的,在生产及使用过程中,对环境不可避免的造成一定污染,而为了响应金山银山不如绿水青山的口号、以及国家环保政策的压力,以水为介质的环氧树脂即水性环氧乳液成了未来行业发展的方向,另外水性环氧乳液含有的有机溶剂量低、节约能源、无污染、储存运输方便、可以在潮湿的环境中使用等优势。但是由于环氧树脂本身不溶于水,不能直接加水进行乳化,再进行水性化修饰时受到技术限制,现今市面上得到的许多水性环氧乳液的成本及各项指标性能都远不及传统的有机溶剂型环氧树脂,并且工艺复杂、放大不可控。
发明内容
本发明为了解决现有技术而提供了一种环氧乳液的制备方法,是采用相反转法来制备的。相反转法是利用乳化剂与环氧树脂混合,并逐渐加水的工艺是体系由油包水状态转变为最终的水包油状态,相反转法制备的乳液稳定性好,工艺简单,利于后续的放大产业化。
为实现上述目的,本发明采用的技术方案为:
一种水性环氧乳液的制备方法,其制备方法步骤如下:
a.一种或多种固体环氧树脂升温溶解在助溶剂中;
b.加入聚醚胺与环氧树脂反应进行开环扩链反应;
c.加入一种或多种有机胺类化合物与环氧树脂进行开环反应,引入胺盐;
d.加入一种或多种有机酸类化合物与胺盐进行中和,引入水性化基团;
e.缓慢加入大量的水,通过相反转获得水性环氧乳液。
本发明选择的环氧树脂为双酚A环氧树脂,环氧当量150~1500之间,优选环氧828、环氧901、环氧194、环氧1001、环氧014U中一种或多种。
本发明选择的助溶剂优选乙二醇丁醚、丙二醇甲醚、甲基异丁酮。
作为本发明所述的制备水性环氧乳液的制备方法的一种优选方案,所述的聚醚胺优选聚醚胺D400、或聚醚胺D2000。
本发明选择的有机胺类化合物优选二乙醇胺、二甲氨基丙胺。
本发明选择的有机酸类化合物优选乳酸、冰乙酸。
本发明的优点:聚醚胺拥有优异的亲水性、反应活性、及柔韧性,首先利用聚醚胺与环氧树脂发生反应,引入长链的醚键,再利用小分子的有机胺化合物与环氧树脂的开环反应,引入胺基,接着运用有机酸类化合物与胺基的中和反应,使环氧树脂具备亲水性。最后利用相反转的原理,缓慢加入大量的水,从而得到环氧乳液。整个反应工艺简单易控,容易后续的放大生产。
