为使得乙烯-醋酸乙烯酯共聚物(EVA)泡沫复合材料具有阻燃功能,分别添加膨胀石墨-聚磷酸铵(EG-APP)和膨胀石墨-聚磷酸铵-热塑性淀粉(EG-APP-TPS)两种不同复配阻燃剂,通过熔融共混和硫化发泡制备了无卤阻燃EVA泡沫复合材料.采用极限氧指数(LOI)、垂直燃烧(UL-94)、热分析质谱联用(TG-MASS)及扫描电镜(SEM)测试等对EG-APP/EVA及EG-APP-TPS/EVA泡沫复合材料进行表征.结果表明:EC-APP复配阻燃剂添加量为30wt％、EG与APP质量比为1∶4时,EG-APP /EVA泡沫复合材料的LOI达28.1％,UL-94为V-1级;而当EG-APP-TPS复配阻燃剂添加量同为30wt％,EG、APP与TPS质量比为1∶4∶1时,EG-APP-TPS/EVA泡沫复合材料的LOI可达29.3％,UL-94为V-0级.TG-MASS和SEM分析表明:EG、APP和TPS在气相和固相中均具有显著的协同阻燃作用.
