| Abstract: |
| The effects of formulation factors on the dynamic ozone resistance of natural rubber were studied.The results showed that，with different curing systems selected in this study，the dynamic ozone resistance of the compounds was similar.With the decrease of the carbon black particle size，the dynamic ozone resistance of the compound with the same hardness showed a tendency to increase.The dynamic ozone resistance of the compound with antioxidant RD/4010NA was the best among the studied antioxidant packages.The addition level of antioxidant 4010NA did not affect the initial cracking time of the compound.The dynamic ozone resistance gradually increased with increasing the addition level of microcrystalline wax. |
