| Abstract: |
| The physical properties and dynamic property of HNBR reinforced by zinc dimethacrylate （ZDMA） before and after hot air aging were investigated experimentally.The results showed that，as the addition level of ZDMA increased，t10 and t90 of HNBR compound shortened，ML and MH increased，the Shore A hardness and modulus at 100% elongation of the vulcanizates increased，and the tensile strength and elongation at break increased at first and then decreased.After hot air aging，as the aging time extended，the Shore A hardness and modulus at 100% elongation of the HNBR vulcanizates increased，and the tensile strength and elongation at break decreased.When the aging time extended or the addition level of ZDMA increased，the storage modulus and loss modulus of the HNBR vulcanizates increased，the peak value of loss factor decreased gradually，and the peak value of loss modulus and glass transition temperature shifted gradually to the high temperature region. |
