| Abstract: |
| In this study, the dispersion of high structure carbon black N234 in SSBR and IIR and the rubber-filler interaction, filler-filler interaction were investigated, and the possibility of using IIR to replace SSBR in the tread compound was explored.The results showed that，the filler dispersion in IIR was worse than in SSBR，and the filler-filler interaction in IIR was stronger，while the filler-rubber interaction was stronger in SSBR.With same curing system，the tensile strength of SSBR vulcanizate increased linearly with the addition level of carbon black，however the tensile strength of IIR vulcanizate with 30 phr carbon black reached maximum，and the tear strength of IIR was much higher than SSBR at high filling level.The dynamic property analysis showed that，the grip performance of winter tire or race tire IIR was improved by using IIR to replace part of SSBR in the tread compound. |
