摘要
概述了近年来利用柔性链段固化剂,核壳聚合物法,液晶增韧法,互穿网络法,纳米粒子增韧等改性环氧树脂的几种方法以及相关的增韧机理,并在此基础上总结了环氧胶粘剂的增韧方法,指出了存在的问题和发展的方向。
New methods to modify epoxy resin,such as flexible curing agent,core-shell polymer, interpenetrating polymer networks (IPN), liquid crystals, toughening by nanometer inorganic particles etc,were reviewed in this paper.This paper introduced correlative mechanism for toughening epoxy resin,then summarized methods for toughening epoxy adhesives. The existing problems and development tendency in toughening epoxy adhesives was directed finally.
