【摘要】 通过加入无卤阻燃剂 (氢氧化镁 )和抑烟剂 (水合硼酸锌 )使高密度聚乙烯达到阻燃抑烟的效果。测试了试样的拉伸强度、弹性模量、断裂伸长率、氧指数、维卡软化点 ,并进行了电镜分析。针对无卤阻燃体系韧性下降很大的缺点 ,采用氨基硅油进行改性。结果表明 ,氨基硅油可在一定程度上改善材料的韧性 ,但同时使材料的拉伸强度和模量大幅下降 ,且不能提高体系的氧指数。

【Abstract】 In this paper, halogen-free flame-retardant(magnesium hydroxide) and smoke suppressant additives(zinc borate) were used to improve the flame retardant behavior of HDPE. The tensile strength,elastic modulus,elongation at break,oxygen index and T VS of the samples were tested,and SEM was employed to observe the morphology of the system. Due to the obvious decrease of the impact strength of halogen-free flame retardant systems,amino silicone oil was used to improve the toughness of the system. The results showed that amino silicone oil could improve the impact strength to a certain extent,but also made the tensile strength and modulus decrease greatly. At the same time the amino silicone oil could not improve the oxygen index of the system.
