摘　　要：聚乙烯的抗静电功能可通过与抗静电剂或导电填料共混来实现,最终的抗静电性能受多种因素影响。在此,两种熔体质量流动速率不同的高密度聚乙烯、一种商业高分子型抗静电剂和一种导电炭黑被用于制备一系列聚乙烯复合材料。结果显示,熔体质量流动速率低的聚乙烯经改性后表面电阻率也相对更低;当导电炭黑含量超过一定阈值后,为聚乙烯带来的抗静电效果要优于同等含量的高分子型抗静电剂,且通过前者改性的聚乙烯在拉伸强度、弯曲模量方面皆优于后者改性的聚乙烯,而冲击强度则相反。The antistatic property of polyethylene(PE) material could be realized by melt blending with antistatic agents or conductive fillers,and the final antistatic performance depended on many factors.Two kinds of high density polyethylene with different melt flow rates(MFR),one commercial polymeric antistatic agent and one conductive carbon black(CB) were used to prepare a series of polyethylene(PE) composites.The results show that the surface resistivity of the modified PE with lower MFR is lower.When the amount of CB exceeds a certain threshold,the CB could lead to better antistatic performance for the composites,comparing with the macromolecule antistatic agent of the same amount.And the CB-modified composites could have relatively higher tensile strength and flexural modulus than the antistatic agent-modified composites,while the impact strength is the opposite.
