摘　　要：系统地研究了高密度聚乙烯(HDPE)和天然气半补强炉法碳黑(CB)为主的复合材料的组成对其室温电阻率的影响。在体系组成为CB 43％～48％(质量分数,下同)、润滑剂6％～8％、交联剂0．5％～1．5％、阻燃剂5％～15％、抗氧剂2．5％时,HDPE／CB复合材料室温电阻率为0．6Ω·m,PTC(正温度系数效应)强度7．76,NTC(负温度系数)强度0．9。The influence of all kinds of components based on HDPE and the natural gas half compensation stove method carbon black（CB） on the composite room temperature electric resistivity was investigated. The least room temperature resistivity and higher PTC in tensity for the composites can be obtained in the system containing CB 43%-48%（mass ratio）, lubricant 6%-48%, cross linking agent 0.5% 41.5%, anti-flammability agent 5% - 15% and anti oxidant 2.5%. The room temperature resistivity is 0.6 Ω·m, the PTC inten sity is 7.76 and the NTC intensity is 0. 9 for the HDPE/CB composite.
