摘　　要：以十溴二苯醚、三氧化二锑为阻燃剂,对包装用低密度聚乙烯薄膜制品的阻燃性能和力学性能进行了研究,并用氧指数测试仪和万能试验机评价其阻燃性能和力学性能。实验结果表明:在DBD-PO/Sb2O3/LDPE体系中,两种阻燃剂之间明显存在协同阻燃效应,极限氧指数大幅度提高;其力学性能也达到了相应的使用标准。The effects of decabromodiphenyl oxide, antimony trioxide and decabromodiphenyl oxide/antimony trioxide on flame retardancy and mechanical properties of low density polyethylene films for packaging were studied,and the flame retardancy and mechanical properties were estimated by a limiting oxygen index apparatus and an universal test machine. The results showed that the application of combining DBDPO or Sb2O3 possessed obvious synergetic effect and exhibited better flame retardancy. And the mechanical properties of the films reached the correlative standrds.
