聚丙烯用阻燃剂的研究进展

Research Progress in Flame Retardants for Polypropylene

综述了聚丙烯用阻燃剂的3种阻燃作用机理,包括气相阻燃、凝聚相阻燃、中断热交换阻燃机理。重点介绍了聚丙烯用阻燃剂的研究开发进展,包括水合金属化合物阻燃剂、磷系阻燃剂、膨胀型阻燃剂、硅系阻燃剂、纳米阻燃剂等。最后,指出纳米无机阻燃剂、膨胀型阻燃剂以及具有高效阻燃、低烟、无毒的复配阻燃剂是聚丙烯用阻燃剂未来的发展趋势。

The action mechanisms of flame retardants for polypropylene were reviewed, including gas phase flame retardancy, condensed phase flame retardancy, and interruptingheat exchange flame retardancy. The research and development status of some flame retardants for polypropylene such as hydrated metal compound flame retardants, phosphated flame retardants, intumescent flame retardants, silicone flame retardants, and nanometer flame retardants were introduced. It was pointed out that the development directions of flame retardants for polypropylene were nanometer inorganic flame retardants, intumescent flame retardants, and compound flame retardants with high-efficiency, low-smoke and non-toxicity.
