摘要
随着高分子材料广泛应用于电气、建筑、医疗、食品包装等领域,其阻燃性能研究也自然受到了国内外学者的关注.有机磷系阻燃剂具有低烟、无毒、低卤、无卤等优点,是阻燃剂未来的发展方向.综述以苯膦酰二氯、六氯环三磷腈和9,10-二氢-9-氧杂-10-磷杂菲三种关键化合物,与羟基、氨基等活泼的端基基团发生反应所制备的一系列新型磷系阻燃剂及其阻燃性能的研究,并对磷系阻燃剂现阶段所遇见的问题进行了总结.在未来研究过程中,可从两方面着手提高磷系阻燃剂工业化程度:一是开发新的阻燃性能更好、相容性更好的磷系阻燃剂;二是利用现有磷系阻燃剂与含有极性基团的高分子材料混合,提高磷系阻燃剂与高分子材料的相容性,从而提高阻燃性能.
Abstract
As polymer materials are widely used in the fields of electrics,construction,pharmaceuticals,food packaging and so on,the research on their flame retardation has attracted the attention of scholars at home and abroad.Organophosphorus-based flame retardants have the advantages of low smoke,non-toxic,low halogen or halogen-free,and they are the future development direction of flame retardants.This paper reviews the research on a series of new phosphorus flame retardants and their flame-retardation properties prepared by reacting three key compounds,namely,phenylphosphonic dichloride,hexachlorocyclotriphosphazene,and 9,10-dihydro-9-oxa-10-phosphaphenanthrene with compounds posscssing active end groups such as hydroxyl and amino groups,and summarizes the problems of phosphorus flame retardants at the present stage.The future research can start from two aspects to improve the scale of industrial production of phosphorus flame retardants.One is to develop new phosphorus flame retardants with better flame-retardation properties and better compatibility;the other is to use the existing phosphorus flame retardants to mix with polymer materials containing polar groups to improve the compatibility of phosphorus flame retardants with polymer materials,thereby improving the flame-retarding properties.
