摘　　要：探讨了无卤和有卤阻燃体系及其复合使用对高密度聚乙烯(HDPE)的阻燃效果,研究了不同阻燃体系的燃烧性能和力学性能。结果表明,十溴联苯醚(DBDPO)与Sb_2O_3在其用量比为3:1时阻燃效果最佳;50份氢氧化镁和20份卤素阻燃剂组成复合阻燃体系的氧指数(OI)高达31.8%,燃烧级别为FH-1。使用不同表面改性剂处理无机填料改善了材料的力学性能,表面改性剂的复配使用比单一使用效果更佳。It discussed the flame retarding effect of flame retarding systems with and without halogen and their compound on HDPE, and studied the combustibility and mechanical properties of different flame retarding systems. The results indicate that： the flame retarding effect is the best when decabromo-diphenyl ether：Sb2O3 =3：1; the OI and combustion level of compound flame retarding system containing 50 phr Mg（OH）2 and 20 phr halogen can be up to 31.8% and FH-1 respectively. The mechanical properties of the composite is improved after the inorganic fillers is treated by different surface modifiers, the effect of compound surface modifier is better that of single modifier.
