摘　　要：以石墨烯和乙炔炭黑分别填充顺丁橡胶(BR),并对其导电性能和物理性能进行研究。结果表明:随着石墨烯用量的增大,石墨烯/BR胶料的焦烧时间和正硫化时间缩短,转矩增大;当石墨烯用量为5份时,石墨烯/BR复合材料的体积电阻率达到1.8×106Ω.cm,复合材料中石墨烯的逾渗阈值为5份;石墨烯/BR复合材料(石墨烯用量为7份)的物理性能与乙炔炭黑/BR复合材料(乙炔炭黑用量为50份)相当。The electrical conductivity and physical properties of BR composites filled with graphene or acetylene carbon black were investigated.The results showed that,the scorch time and optimum curing time of graphene/BR compound were shortened,and the torque increased as the addition level of graphene increased.The percolation threshold of graphene in graphene/BR composite was 5 phr,when the volume resistivity of graphene/BR composite reached 1.8×106 Ω·cm.The physical properties of BR composite with 7 phr of graphene were quite similar to the BR composite with 50 phr of acetylene carbon black.
