摘要
针对聚丙烯腈(PAN)纤维极限氧指数较低,易燃,在阻燃性能要求较高领域中的应用受到限制的情况,综述了阻燃PAN的主要制备方法,分析了各种制备方法的原理和优缺点,并介绍了阻燃PAN的阻燃机理,总结了国内外阻燃PAN的研究现状和最新研究进展。从环境保护和制备工艺方面综合考虑,指出选用工艺流程简单和应用无卤无毒添加型阻燃剂的共聚法和共混法是阻燃PAN的发展趋势。
The limit oxygen index of polyacrylonitrile fiber is low,which means flammable characteristic and limits its application in the many fields with flame retardant performance requirements.Main preparation methods of flame retardant polyacrylonitrile are reviewed,as well as their principles,advantages and disadvantages.The mechanism of flame retardant polyacrylonitrile is introduced.The recent research development and latest progress of flame retardant polyacrylonitrile at home and abroad are summarized.Based on the environmental protection and preparation technology,it is pointed out that copolymerization and blending with halogen-free and non-toxic additive flame retardants are the future development trends of flame retardant polyacrylonitrile.
