水性环氧树脂的制备方法

文章来源:康裕   作者:康裕   发布时间:2017-10-28 09:32   浏览次数:

  水性环氧树脂通常是指环氧树脂以微粒、液滴或胶体形式分散于水相中所形成的乳液、水分散体或水溶液,三者之间的区别在于环氧树脂分散相的粒径不同。根据制备方法的不同,环氧树脂水性化有以下四种方法:机械法、化学改性法、相反转法和固化剂乳化法等。

  一般多在环氧树脂链上引入亲水性聚氧乙烯基团,同时保证每个改性环氧树脂四川11选5走势图分子中有两个或两个以上环氧基,所得的改性环氧树脂不用外加乳化剂即能自分散于水中形成乳液。如用分子量为4000~20000的双环氧端基乳化剂与环氧当量为190的双酚A环氧树脂和双酚A混合,以三苯基膦化氢为催化剂进行反应,可制得含亲水性聚氧乙烯、聚氧丙烯链端的环氧树脂,该树脂不用外加乳化剂便可溶于水,且耐水性增强。另外,这种方法制得的粒子较细,通常为纳米级,前面两种方法制得的粒子较大,通常为微米级。从此意义上讲,化学法虽然制备步骤多,成本高,但在某些方面具有实际意义。
