阻燃聚乙烯塑料的阻燃性能实验

Properties of Flame Retardant PE Plastics

为提高聚乙烯塑料的阻燃性，扩大其应用范围，选用含卤阻燃剂（Ｃｌ７０）及Ｓｂ２Ｏ３作为复合阻燃剂，考察了阻燃剂对聚乙烯塑料阻燃性和力学性能的影响。实验结果表明：加入阻燃剂的聚乙烯阻燃性可达ＧＢ２４０８—８０标准，力学性能略有下降。

In order to enhance the flame retardancy of PE andextend its applications in various fields, we select the halide flame Retardants, (Cl 70) and Sb 2O 3, as compound flame retardant. The effects of of these retardants on flame retardancy and mechanical properties of PE are tested. The experimental results show that the flame retardancy of PE comes up to the GB 2408-80, and the mechanical properties of PE are reduced slightly.
