| 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)/乙烯-醋酸乙烯酯共聚物(EVA)/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/EVA/OMMT/氢氧化铝(ATH)/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5%(质量分数)OMMT可以提高PP/EVA复合材料的阻燃性能,燃烧时的热释放速率、质量损失率以及烟释放量减少,且OMMT与无卤复配阻燃剂之间可产生阻燃协同作用,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。

| Abstract: | The heat release rate,smoke emission and mass loss behavior of polypropylene(PP)/ ethylene-vinyl acetate copolymer(EVA)/organophilic montmorillonite(OMMT) nanocomposites and its flame retarded nanocomposites prepared of PP/EVA/ aluminium trihydroxide(ATH)/antimony trioxide(AO) by additions of non-halogen mixture as flame retardants were studied using Cone Calorimeter,LOI and UL-94 vertical burning test at 35kW/m2.It was found that the addition of 5%(wt) OMMT could increase flame retardancy of PP/EVA composi... |
