以氯化铜熔盐掺杂无烟煤为导电填料 ,并通过偶联剂界面处理 ,与高密度聚乙烯熔融共混 ,成功制备了HDPE/无烟煤导电复合材料 ,通过力学性能测试、扫描电镜观察、电导率测试等手段研究了其结构与性能。结果表明 :复合材料拉伸强度在填充量 2 0 %以内均高于基体树脂 ,在 10 %附近取得最大值 ;断裂伸长率有所下降 ,但仍高于10 0 % ;电阻率变化符合逾渗规律 ,在填充量为 15 %时 ,电阻率下降到 2 .2 4× 10 7Ω·cm ,达到了抗静电材料的要求 The anthracite was doped with copper chloride molten salt as the conductive filler, and was melt blended with high density polyethylene through the coupling agent interface to prepare the HDPE / anthracite conductive composite successfully. The mechanical properties, scanning electron microscopy and conductivity Rate test and other means to study the structure and performance. The results show that the tensile strength of the composites is higher than that of the matrix resin with the loading of 20%, and the maximum value is obtained at around 10%. The elongation at break of the composites is decreased but still higher than 10% Permeability law, the resistivity dropped to 2.24 × 10 7Ω · cm at a filling amount of 15%, to meet the requirements of antistatic materials
