摘要
以氢氧化镁为阻燃剂,硬脂酸钠为改性剂,将不同添加量的氢氧化镁加入到聚乙烯中,测试所得复合材料的阻燃与力学性能,并对比改性前后力学性能及阻燃性能的差异。结果表明随着氢氧化镁添加量的增加,复合材料的力学性能逐渐下降,氧指数逐渐上升。经改性处理后的复合体系较未处理的复合体系力学性能下降略为平缓,氧指数上升明显。
Applied stearic acid sodium as modifier,the flame retardant of polyethylene filled with magnesium hydroxide was investigated.And the mechanical properties and flame retardant properties of composite materials after modified were compared with that of without modified.The results showed that the mechanical properties decreased with the increases of magnesium hydroxide addition,as the oxygen index increased.After modification,the composite system decreased slightly and the oxygen index increased significantly.
