| Abstract: |
| The carbon black was modified by castor oil acid，and the influence of modified carbon black on the properties of NR compound was investigated.The results showed that，compared to those of normal carbon black，the interaction between modified carbon black and rubber was reduced，the mass fraction of bound rubber was decreased，the number of flexible contact point and tensile strength were increased，the particle aggregation of carbon black was weakened and the dispersion of modified carbon black in NR compound was improved. |
