Abstract:
      The effect of the addition level of anti-scorching agent CTP on the silica filled composite was investigated.The influence and mechanism of the addition level of anti-scorching agent CTP on the dynamic mechanical properties of the vulcanizate were emphatically analyzed.The results showed that as the addition level of CTP increased，the scorch time of the compound was significantly prolonged，the Mooney viscosity changed little，the curing rate slowed down.The hardness，tensile strength and tear strength of vulcanizates changed little，the modulus decreased，the elongation at break showed an increasing trend，the rebound decreased slightly，but the difference was small.The compression fatigue temperature rise and compression set of vulcanizates increased，the loss factor increased significantly.Filler network strengthened and crosslink density reduction might be the reason of these changes.
