| 中文摘要: |
| 通过与BR的对比,研究了国产丁戊橡胶(BIR)的加工性能、硫化特性、物理性能,并探讨了BIR与BR在胎面胶中的加工应用性能差异。结果表明,BIR硫化速度快,门尼粘度低,加工性能好；BIR硫化胶撕裂强度高,压缩温升低,耐疲劳性好。NR/SBR/BIR并用体系胎面胶硫化速度快,加工性能好；硫化胶的撕裂强度、耐疲劳、抗湿滑等性能均优于NR/SBR/BR并用体系。 |
| 英文摘要: |
| In this paper, the processability, vulcanization characteristics and mechanical properties of domestic Butadiene-isoprene rubber(BIR) were studied, comparing with those of butadiene rubber( BR). And the differences of processing and application performance for the tread compound between BIR and BR were discussed. The results showed that, BIR possessed faster vulcanization rate, lower Mooney viscosity and better processability; BIR vulcanizate got the higher tear strength, lower compression temperature rising and better fatigue resistance. Tread compound with NR/SBR/BIR blending system had faster vulcanization rate, better processability; and the performances of tear strength, fatigue resistance and wet-skid |
