摘　　要：研究以华光导电炭黑填充天然橡胶和氯丁橡胶胶料的电阻率随温度变化的规律，试验结果表明：两种炭黑填充的胶料均具有ＮＴＣ效应；以华光ＨＧ－Ⅱ导电炭黑最为明显，且当用量小于２０Ｐｈｒ时，胶料的电阻率对温度较敏感。Negative temperature coefficient effect of compound filled with HG conductive carbon black were investigated. The test results showed that the compound filled with two types HG conductive carbon black had NTC effect and the HGconductive carbon black was most obvious. The resistivity of the compound was sensitive to temperature when HG- carbon black content in NR was less than 20phr.
