| Abstract: |
| The effects of addition levels of curing agent and accelerator of DCP/TCY curing system on the physical properties of EPDM/ACM blend were investigated by using orthogonal design method.The results showed that，the addition levels of sulfur and zinc oxide had very significant effect on the tensile strength of EPDM/ACM blends，and the addition level of curing agent DCP also had some influence on it.The addition levels of DCP， TCY and sulfur had very significant effect on the tear strength of the blends，and zinc oxide showed certain influence on it.In addition， curing agent DCP，accelerator DM and zinc oxide had influence on the aging resistance.The optimized curing system was as follows: curing agent DCP 3，curing agent TCY 2，sulfur 0.3，accelerator DM 0.25，and zinc oxide 5. |
