| Abstract: |
| The influence of the content of ENR on the processability，dynamic mechanical properties and physical properties of NR/carbon black composites were investigated.It was found that the processability of the composites was improved by adding appropriate amount of ENR. ENR acted as a compatibilizer in the composites，the dispersion of carbon black in rubber matrix was improved，the bound rubber content increased，and the dynamic mechanical properties，physical properties and aging resistance of the vulcanizates were improved.When the addition level of ENR was 3～4.5 phr，the NR/carbon black composites possessed the best comprehensive properties.The test results by RPA and DMA indicated that，the wet skid resistance of NR/carbon black composites could be significantly improved with ENR，but the rolling resistance increased only slightly. |
