Abstract: |
The action mechanism of blended accelerator EZ/PPD/CZ/TETD in sulfur curing system for EPDM was analyzed.The results showed that the amine cracking from the blended accelerator systems during the curing process could activate the accelerator and rubber molecule chain,and make the vulcanization reaction easier;the reverse reaction of the curing system took place in the later stage of vulcanization,and had no retardant effect on the induction and curing stages,which was one of the reasons for promoting the curing speed. |
