| Abstract: |
| The influence of the carbon black kind and level as well as the usage of silane coupling agent Si69 on the static and dynamic properties of black-reinforced EPDM was studied.The abrasion surface from Akron test was analysed with SEM and the dynamic heat build-up in EPDM compound was measured with improved Goodrich compression fatigue tester.The results showed that the black-reinforced EPDM compound possessed lower heat build-up，higher heat resistance and significantly improved dynamic properties after ageing ；the dynamic heat build-up decreased significantly by using the
carbon black treated with the silane coupling agent Si69 ；the EPDM compound had better resilience，lower dynamic heat build-up and higher property retention after ageing when compared with the SBR truck tread compound，thus it was suitable to the rubber goods that worked dynamically at high temperature. |
