摘　　要：研究丁腈橡胶(NBR)/氯丁橡胶(CR)并用比、硫化体系和补强体系对NBR/CR并用胶物理性能和导电性能的影响。结果表明:当NBR/CR并用比为70/30,氧化锌、氧化镁、硫黄和促进剂DM用量分别为6,6,4和0.6份,炭黑N550用量为50份时,并用胶的物理性能最佳,体积电阻率适当。The effects of NBR/CR blending ratio,curing system and reinforcing system on the physical properties and conductivity of NBR/CR blends were investigated. The results showed that,when the NBR/CR blending ratio was 70/30,the amounts of zinc oxide,magnesium oxide,sulfur and accelorator DM were 6 phr,6 phr,4 phr and 0. 6 phr,respectively,and the amount of carbon black N550 was 50 phr,the physical properties of the blend were the best,and its volume resistivity was proper.
