聚合物本质阻燃改性研究新进展

Research progress in inherent flame retardance modification of polymer

聚合物本质阻燃改性通过共聚的方式,将磷、氮、硅和卤素等阻燃元素或耐高温单体直接引入聚合物主链或侧链中,以提高聚合物材料的阻燃性,克服了一般添加型阻燃剂易于从聚合物表面迁移或挥发的缺点,且除提高阻燃性能外对聚合物的其他性能影响较小。按照聚合物材料和引入阻燃元素的不同类型,综述了近3年聚合物本质阻燃改性的研究进展,展望了其发展方向,指出无卤型反应性新单体的设计是聚合物本质阻燃改性的关键。

Overcoming the disadvantages of adding additive that the flame retardant is easy to move or evaporate from the polymer matrix,the inherent flame retardance modification of polymer exhibits superior flame retardance,it can greatly enhance the flame-retardant property without changing other properties.Inherent flame retardance modification of polymer usually is realized via copolymerization with a functional monomer containing flame retardant elements,such as P,N,Si and ha!ogen.Classifying as different polymer and flame retardant type,the recent progresses in the inherent flame retardanee modification of polymer were reviewed and prospected their development direction.It can be pointed out that the design of non-halogen reactive monomer,was the key to the modification of inherent flame retardance of polymer.
