摘要
环氧树脂成本低廉、性能优异,应用范围广泛.目前研究人员多对其进行增韧改性,以弥补结构不足,进一步扩展其应用范围.其中,液体丁腈橡胶增韧改性环氧树脂是应用最成功的方法之一.本文简介了环氧树脂的增韧机理,综述了近年来各类液体丁腈橡胶,如端羧基液体丁腈(CTBN)、端羟基液体丁腈(HTBN)、无规羧基液体丁腈(XNBR)、液体丁腈(LNBR)、端胺基液体丁腈(ATBN)和端环氧基液体丁腈(ETBN)等增韧环氧树脂的研究进展,并对液体丁腈橡胶增韧环氧树脂的研究方向进行了展望.
Abstract
Epoxy resin has low cost,excellent performance,and a wide range of applications.Currently,researchers are mostly modifying its toughness to compensate for structural deficiencies and further expand its application range.Among them,toughening modified epoxy resin with liquid nitrile rubber is one of the most successful methods in application.In this article,the toughening mechanism of epoxy resin was briefly introduced,the research progress of various liquid nitrile rubbers,such as carboxyl terminated liquid nitrile(CTBN),hydroxyl terminated liquid nitrile(HTBN),random carboxyl terminated liquid nitrile(XNBR),liquid nitrile(LNBR),amino terminated liquid nitrile(ATBN)and epoxy terminated liquid nitrile(ETBN)in toughening epoxy resin in recent years was reviewed,and the research direction of toughening epoxy resin with liquid nitrile rubber was prospected.
