| 中文摘要: |
| 对比研究炭黑和炭黑/白炭黑填充钴系BR0150/NR与炭黑填充镍系BR9000/NR在轮胎胎侧胶中的应用。结果表明：与炭黑填充BR9000/NR胶料相比，炭黑填充BR0150胶料的门尼粘度较小，流动性较好，正硫化时间和焦烧时间相近，硫化胶的各项性能相差不大；炭黑/白炭黑填充BR0150/NR胶料门尼粘度较大，正硫化时间延长，硫化胶的物理性能和老化性能相差不大，但撕裂强度大幅增大，抗切割性能和耐屈挠割口增长性能改善。 |
| 英文摘要: |
| The application of carbon black or carbon black/silica filled cobalt based BR0150/NR and carbon black filled nickel based BR9000/NR in tire sidewall compound was investigated.The results showed that，compared with the carbon black filled BR9000/NR，the Mooney viscosity of carbon black filled BR0150 compound was lower，the flowability was better，the optimum curing time and scorch time were similar，and the properties of vulcanizates were also similar；the Mooney viscosity of carbon black/silica filled BR0150/NR compound was higher，the optimum curing time was longer，the physical property and aging property of vulcanizates were similar，but the tear strength increased significantly，and anti-cutting performance and flexing resistance were improved. |
