摘要

探索水溶性聚磷酸铵阻燃剂对汽车内饰件用木纤维/麻纤维/聚丙烯纤维三元复合材料性能的影响。将复合材料卷材浸渍阻燃剂后,经热压-冷压定型,测试其吸水性、抗弯性能和阻燃性能。结果表明:聚磷酸铵处理后复合材料的吸水性和阻燃性能有所改善,弯曲强度降低,但仍可满足应用要求;燃烧速率降为0,成炭率和极限氧指数有所升高。当板材增重率为43.9%时,极限氧指数超过27%,满足国标GB 50222-1995《建筑内部装修设计防火规范》（2001版）中B2级要求。

Abstract

Wood/jute/polypropylene（PP）fiber panels are used forautomotive interior trims when fiber mat is hot pressed into composite panels.Prior to pressing,the fiber mats were impregnated with water-soluble ammonium polyphosphate fire retardant,and then the fire retardant effectiveness for the panels was tested.The test result indicated that water absorption and fire retardancy were all improved but the modulus of rupture（MOR）of the panels was reduced slightly.Combustion speed was reduced to 0mm/min while char yield and limiting oxygen index（LOI）were increased.When weight gain rate of the panels reached 43.9%,the sample’s LOI was 27.84%,which met the requirement of the National Standard GB 50222-1995（2001）for the B2 grade.
