| 中文摘要: |
| 通过在不同温度下分别对4种炭黑进行热处理，研究热处理炭黑对结合橡胶质量分数和表面官能团含量的影响。结果表明：炭黑N330和N550经400 ℃热处理后表面官能团脱落，600 ℃处理后再次结合；炭黑DZ13经200 ℃热处理后表面官能团脱落，400 ℃处理后再次结合；炭黑DZ20经200 ℃热处理后表面官能团结合，600 ℃处理后再次脱落。炭黑DZ20的补强性能主要受内酯基的影响，而炭黑N330，N550和DZ13的补强性能主要受酚羟基的影响。 |
| 英文摘要: |
| 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. |
