Abstract:
      The vulcanization behaviour of M or DM containing NR compounds was studied and their effects on the processibility and physical properties were in detail respectively investigated.The results showed that the accelerator M gave more rapid scorch rate and cure rate,but worse cure plateau than the accelerator DM.The accelerator M gave larger plastication to NR than DM at lower temperature,but DM would give larger plastication than M as the temperature increased.The fact that the activation energy of M was much lower than that of DM implied less dependence of its cure rate on temperature than that of DM.In addition,the tensile strength,modulus,tear resistance and rebound resilience of M containing compound were somewhat lower than those of DM containing compound,but the former gave better heat-aging resistance than the latter.
