摘要
文中以纳米海泡石（以下简称海泡石）作为增效剂，制备了阻燃乙烯-醋酸乙烯共聚物（ethylene-vinyl acetate copolymer
EVA）复合材料。根据材料配方制备样品，并通过硬度、拉伸试验、热失重分析、氧指数和锥形热量计测试等试验，研究海泡石对镁磷体系阻燃EVA的机械性能、热性能和阻燃性能的影响。结果表明，随着海泡石添加量的增加，样品硬度呈上升趋势，断裂强度呈下降趋势，断裂伸长率呈先上升后下降的趋势。绝缘电阻方面，海泡石的添加量小于2 g时，样品的体积电阻率升高；海泡石的添加量超过2 g时，样品的体积电阻率急剧下降。热性能方面，随着海泡石添加量的增加，样品的初始熔融温度、熔融峰、结晶温度和结晶度等均先升高后降低。受热过程有3个失重阶段，第一分解峰温度在海泡石添加量小于2 g时变化较小，海泡石添加量大于2 g时下降幅度较大；随着海泡石添加量的增加第二分解峰温度从383.8℃下降至375.9℃，第三分解峰温度基本保持不变。极限氧指数测试中，随着海泡石添加量的增加，极限氧指数逐渐上升，从32.7%上升至34.7%。锥形量热试验中，添加适量的海泡石可以有效降低火灾行为参数。灰烬图片显示，海泡石添加量为2 g时，能够与阻燃剂形成致密的结壳层，起到阻碍火苗向内部扩散的作用。
