Abstract

本发明涉及光致变色树脂技术领域，特别是一种光致变色环氧丙烯酸酯树脂及其制备方法和应用，一种光致变色环氧丙烯酸酯树脂的制备方法，包括以下步骤：二噻吩并环戊二烯‑4‑酮与乙炔钠进行亲核加成反应后产物与萘酚进行环化反应合成第二中间产物；第二中间产物进行硝化反应、硝基还原反应和重氮化‑水解反应合成第五中间产物；第五中间产物与环氧氯丙烷进行亲核取代反应合成第六中间产物；第六中间产物引入α‑取代丙烯酸类化合物好人溴代离子液体官能团化合物获得第八中间产物；第八中间产物与铵盐进行阴离子交换反应得到目标产物，解决传统光致变色材料应用于水性涂料时，不能很好地适配水性体系且所得涂层机械强度不足，耐磨性差的问题。
