Abstract:
      Using bromobutyl rubber（BIIR） compounds as comparative objects，the effect of naphthenic oil amounts on the properties of C 5petroleum resin/BIIR composites was studied.The results revealed that，with the increase of naphthenic oil amount，the Mooney viscosity andFmax-FLof BIIR compound and C5 petroleum resin/BIIR composites decreased，the t10t90 first prolonged and then shortened，the Payne effect was weakened，the Shore A hardness and tensile strength decreased，the elongation at break and rebound value increased，the compression set first increased and then decreased，the effective damping temperature range moved towards lower temperature direction，the peak of loss factor （tanδmax ） increased.When naphthenic oil amount was the same，compared with BIIR compound，the Mooney viscosity and Fmax-FL of the C5petroleum resin/BIIR composite decreased，the t10 and t90 prolonged，the Payne effect was weakened，the Shore A hardness and rebound value decreased，the elongation at break increased，the effective damping temperture range was expanded and moved towards high temperture direction.
