| Abstract: |
| The application of new compound activators（composed of mica powder，antioxidant BHT，stearic acid and accelerator）in ground tire was investigated.The results showed that，the regeneration effect and physical properties of the reclaimed rubber were the best when the accelerator PZ was added into the compound activator.When the addition levle of accelerator PZ was 0.5 phr，the regeneration effect and physical property of regenerated rubber were better than other dosages.The processing performance of reclaimed rubber which accelerator PZ was dissolved in the environmental protection oil at once before adding was better，but the physical properties of that which accelerator PZ was dissolved step by step before adding were better，and the way to add accelerator PZ could be choosen according to the processing performance or physical properties requirements. |
