| Abstract: |
| The vulcanization characteristics and mechanical properties of HNBR with curing co-agent oligomer ester or TMPTMA were studied，and the influence of these two curing co-agents on the vulcanization characteristics，mechanical properties，high temperature tensile properties，aging behavior，wear resistance and processing properties of HNBR was compared.The results showed that，with the increase of oligomer ester or TMPTMA content，the torque of rubber compound increased，the curing time was shortened，tensile strength remained basically unchanged，hardness，modulus at 100% elongation and tear strength gradually increased，and elongation at break and resilience decreased.Compared with oligomer ester，the torque of rubber compound with TMPTMA was higher，vulcanization time was shorter，and the physical properties，aging behavior，high temperature tensile properties and wear resistance were close，indicating that their action mechanisms in the vulcanization process were similar. In addition，the storage modulus of rubber compound with TMPTMA was smaller，and its loss factor was larger. |
