| Abstract: |
| The low hysteresis carbon black DZ13 was used to replace part of carbon black N234 in the tread compounds based on NR，NR/BR and NR/BR/SSBR，and the effect of DZ13 on the physical properties and fatigue failure behavior of the vulcanizates was investigated.The results showed that，the physical property change of three vulcanizates was similar，i.e.，the modulus increased slightly，elongation at break and tear strength decreased.The change in wear resistance，compression fatigue property and cut growth resistance depended on the rubber matrix type.For NR/BR vulcanizate，the flex property was improved，but the morphology of failure interface was rougher. |
