Abstract:
      Abstract：The preparation and properties of epoxidized natural rubber（ENR）/ethylene-propylenediene rubber（EPDM） blend with hybrid cross-linking network was studied. The results showed that，when the addition level of curing agent DCP was fixed，with the increase of the addition level of zinc acrylate，the modulus at 100% elongation and tensile strength of ENR/EPDM blend increased，and the elongation at break increased first and then decreased. When the addition level of zinc acrylate was fixed，with the increase of the addition level of curing agent DCP，the modulus at 100% elongation of ENR/EPDM blend increased，and the tensile strength，elongation at break and tear strength decreased. ENR/EPDM blends with hybrid crosslinking network structure had the characteristic structure of both ENR and EPDM，and tensile properties of the blends in the repeated tensile tests were better than those of ENR and EPDM compound.
