聚氯乙烯树脂阻燃抑烟性能的研究进展

摘要

介绍了聚氯乙烯(PVC)阻燃抑烟剂的两种作用机理,即Lewis酸机理、还原偶合机理.根据化学组分的不同,把PVC阻燃抑烟剂分为无机阻燃抑烟剂、有机阻燃抑烟剂以及复合阻燃抑烟剂3类.综述了不同类型阻燃抑烟剂的阻燃抑烟机理和阻燃抑烟性能的研究进展,并展望了PVC阻燃抑烟剂的发展趋势与应用前景.%The action mechanisms of flame retardants and smoke suppressants for polyvinyl chloride are reviewed, including Lewis acid, reductive coupling. The additive agents are divided into three types, including inorganic flame retardants and smoke suppressants, organic flame retardants and smoke suppressants, and compound flame retardants and smoke suppressants. Performances and mechanisms of different flame retardants and smoke suppressants are reviewed. And the future development trend of flame retardant and smoke suppression of PVC is prospected.
