| 中文摘要: |
| 采用研磨和偶联剂乙烯基三乙氧基硅烷（VTEO）对热解炭黑（CBp）进行改性处理，研究研磨改性CBp和VTEO改性CBp补强对丁苯橡胶（SBR）胶料性能的影响。结果表明：随着研磨时间的延长，CBp粒径减小，与橡胶大分子链的相互作用增强，研磨改性CBp补强SBR胶料的门尼粘度和Fmax－Fsub>L增大，硫化胶的物理性能提高；VTEO改性使CBp补强SBR胶料的t10延长，加工安全性提高，当采用1份VTEO改性50份CBp时，硫化胶的拉伸强度提高1.6 MPa。 |
| 英文摘要: |
| Pyrolysis carbon black（CBp） was modified by grinding and coupling agent vinyl triethoxysilane（VTEO），and the effects of grinding modified CBp and VTEO modified CBp on the properties of SBR compound were studied.The results showed that，with the increase of grinding time，the particle size of CBp decreased，and the interaction between CBp and rubber macromolecular chain was enhanced.The Mooney viscosity and Fmax－Fsub>L of grinding modified CBp reinforced SBR compound increased，and the physical properties of vulcanizates were improved.The t10 of VTEO modified CBp reinforced SBR compound was prolonged，which meaned the processing safety was improved.When 1 phr VTEO was used to modify 50 phr CBp，the tensile strength of vulcanizate increased by 1.6 MPa. |
