Abstract:
      The properties of pyrolytic carbon black（CBp） reinforced natural rubber（NR）/butadiene rubber（BR） blend and CBp and CNTs synergistically reinforced solution-polymerized polystyrene-butadiene rubber（SSBR）/NR blend were investigated，and compared with carbon black N234 reinforced NR/BR blend and SSBR/NR blend，respectively.The results showed that，compared with carbon black N234，CBp could delay the vulcanizations of the compounds.Compared with carbon black N234 reinforced NR/BR blend，the tanδ at 60 ℃ of CBp reinforced NR/BR blend was significantly smaller，indicating that CBp could reduce the rolling resistance of NR/BR blend to a certain extent.In CBp and CNTs synergistically reinforced SSBR/NR blend，the reinforcement effect of CNTs on SSBR/NR blend was obvious.The comprehensive physical properties of 30 phr CBp and 2 phr CNT synergistically reinforced SSBR/NR blend were equivalent to those of 20 phr carbon black N234 reinforced SSBR/NR blend，and the tanδ at 0 ℃ increased，indicating that CNTs could improve the wet skid resistance of SSBR/NR blend.
