| Abstract: |
| Four types of carbon black were treated under different temperatures，the effect of heat treatment of carbon black on the bound rubber content of carbon black/NR compound and content of surface functional groups was investigated.The results showed that，the debonding and bonding of surface functional groups of carbon black N330 and N550 took place at 400 ℃ and 600 ℃，respectively.The debonding and bonding of surface functional groups of DZ13 occurred at 200 ℃ and 400 ℃， respectively.On the other hand，the surface functional groups of carbon black DZ20 bonded at 200 ℃ and then the bonding was broken at 600 ℃.The reinforcing property of carbon black DZ20 was particularly influenced by lactone groups，and the reinforcing property of carbon black N330，N550 and DZ13 was mainly influenced by phenolic hydroxyl groups. |
