Abstract:
      The different vulcanization system on NR dynamic propertywas studied by RPA.with frequency increasing, the G '' of compounds and vulcanizates increased, the Tanδ of compounds reduced, the Tanδ of vulcanizates increased;with Strain increasing, the G '' of compounds and vulcanizates decreased,the Tanδ of compounds increased rapidly when the strain is more than 20% , the Tanδ of vulcanizates appeard peak value in the strain of 2%;with temperature increasing, the G '' of compounds reduced and the Tanδ increased,the G'' of vulcanizates increased and the Tanδ decreased.Under three scan of different vulcanization system, G '' of vulcanizates order: SEV > EC >CV > EV, mostly single sulphur keys, double sulfur and more sulfur keys must keep certain proportion to obtain higher G''.
