| 摘 要： | 利用锥形量热仪(CONE)在35kW/m2热辐照条件下,并结合极限氧指数(LOI)和UL-94垂直燃烧测试方法对聚丙烯(PP)/聚醋酸乙烯酯(PVAc)-有机蒙脱土(OMMT)纳米复合材料和加入无卤复配阻燃剂制备的PP/PVAc-OMMT/氢氧化镁(MH)/三氧化二锑(AO)纳米复合阻燃材料的热释放速率、烟释放及材料在燃烧时的质量损失行为进行了研究。结果表明,添加10%(质量分数)PVAc-OMMT可以提高PP材料的阻燃性能,燃烧时的热释放速率、质量损失率以及烟释放量减少,且PVAc-OMMT与无卤复配阻燃剂之间可产生阻燃协效作用,使纳米复合阻燃材料的阻燃性能、热稳定性和抑烟性进一步增强。
