| Abstract: |
| The influence of complex accelerator DB and sulfur on the properties of EPDM was investigated.The results showed that，when DB was added in hose compound，the heat aging resistance of the compound was excellent，the aminolysis reaction of polyester cord didn’t occur，and the working life of the hose was extended.When DB was added in molded goods，the curing rate was moderate and the flow property of the compound was good，which resulted in excellent adhesion between rubber and metal parts. |
