| Abstract: |
| The effect of blending ratio on the curing behavior，physical properties，hot air aging resistance，ozone aging resistance and change of loss factor(tanδ) at different temperature of NR/BIIR blend was investigated.The results showed that，the curing speed of NR compound increased after blending with BIIR.As the content of BIIR increased，the physical properties of NR/BIIR blends reduced，and the hot air aging resistance and ozone aging resistance improved.The flexing resistance of NR was significantly improved after blending with a certain content of BIIR.As the content of BIIR increased，the tanδof NR/BIIR blend increased，and NR/BIIR blend possessed greater loss and better damping characteristics in a wide temperature range. |
