| Abstract: |
| The influence of the addition level of environmentfriendly accelerator TBzTD and the reclaiming time on the reclaiming results of ground tire rubber were investigated. The results showed that，as the addition level of accelerator TBzTD increased or the reclaiming time extended， the Mooney viscosity of reclaimed rubber decreased， the tensile strength and elongation at break of the vulcanizates increased at first and then decreased. When reclaiming time was 10 min and the addition level of accelerator TBzTD increased， the storage modulus and loss modulus of the vulcanizates increased，and the loss factor tended to increase at first and then decrease. When the addition level of accelerator TBzTD was l. 69一2.25 phr，and the reclaiming time was 10 min，the overall properties of reclaimed rubber was better. SEM analysis results indicated that the vulcanizates with accelerator TBzTD had good interfacial bonding. |
