摘　　要：在实际生产中,苯并噁嗪树脂200℃以上的固化温度限制了其在先进复合材料领域的大规模应用,研究苯并噁嗪树脂开环聚合机理,优化苯并噁嗪树脂固化特性,从而获取降低苯并噁嗪树脂固化温度的方法具有重要意义。因此,对国内外近些年关于降低苯并噁嗪树脂固化温度的研究进展进行了综述,并对通过向苯并噁嗪单体中引入活性官能团以及添加固化催化剂来实现苯并噁嗪树脂中低温固化的方法进行了详细介绍,分析了其反应机理,明确了其固化反应影响因素,并对比分析了这两类方法的特点。从分子角度出发,向单体中引入活性基团具有更高的灵活性,但改性工艺相对复杂,大批量工程化生产存在难度;相比较而言,添加合适的催化剂可显著降低苯并噁嗪树脂的固化温度,操作工艺较易实现,是目前最简单有效的方法之一。综述涵盖了多种催化剂的研究,对于优化苯并噁嗪树脂的固化条件,制备高性能苯并噁嗪树脂具有借鉴意义。In practical applications,the curing temperature of benzoxazine resin above 200℃limits its largescale use in the field of advanced composite materials,so it is of great significance to study the ring-opening polymerization mechanism of benzoxazine resin,optimize the curing characteristics of benzoxazine resin,and obtain the method to reduce the curing temperature of benzoxazine resin.This paper reviews the research progress on reducing the curing temperature of benzoxazine resin in recent years at home and abroad.The method of introducing active functional groups into benzoxazine monomer and adding curing catalyst to achieve medium-low temperature curing of benzoxazine resin was introduced in detail.The reaction mechanism was analyzed,the influencing factors of curing reaction were clarified,and the characteristics of the two kinds of methods were compared.From the molecular point of view,the introduction of active groups into monomers has higher flexibility,but the modification process is relatively complex.It is difficult to engineer large quantities of production.In comparison,the curing temperature of benzoxazine resin can be significantly reduced by adding a suitable curing catalyst,and the operation process is easy to achieve,which is one of the simplest and most effective methods at present.This review covers various studies on curing catalysts,providing insights for optimizing the curing conditions of benzoxazine resin and preparing high-performance benzoxazine resin materials.
