    摘要:

    基于自身低熔融黏度、固化过程不需添加催化剂、聚合过程中无小分子释放以及固化后树脂卓越的力学性能,近年来苯并噁嗪引起了学术界和诸多工业制造及生产行业的极大兴趣。尽管苯并噁嗪单体含氧、氮六元杂环结构,开环后聚合生成类似酚醛树脂的网状结构,不易燃烧,但仍无法满足高阻燃场合的应用需求。文中从苯并噁嗪的本体改性、共聚改性及物理共混改性三方面,综述了近些年苯并噁嗪树脂阻燃改性的一些研究成果,概述了其作为阻燃协效剂的应用,并对其阻燃改性方法及阻燃应用方向进行了展望。

    Abstract:

    In recent years, benzoxazine resins have attracted increasing attention in academia and many industrial manufacturing industries due to good thermal, chemical, electrical and mechanical properties, in addition to their low melt viscosity, the addition of no catalyst and no small molecule released during the curing process. The benzoxazine monomer has sixelement O, N-containing heterocyclic structure, and a compound with N-containing mesh structure similar as phenolic resin can be polymerized through ringopening polymerization, which is hard to burn, however, the flame retardant property of traditional benzoxazine resin still can not meet application demand of high flame retardant field, which restricting their applications as matrices for some high-performance composites. Therefore, the flame-retarded modification and application of benzoxazine have aroused great interest. In this paper, the flame-retarded modification of benzoxazine resin in recent years were reviewed from the aspects of intrinsically flame-retarded modification, copolymerization modification and physical blending modification. Meanwhile, the application of benzoxazine as flame retardant synergist was summarized, and the flame retardant modification directions of benzoxazine were prospected.
