| 中文摘要: |
| 研究裂解炭黑在半钢子午线轮胎气密层胶中的应用。结果表明：裂解炭黑的比表面积和结构度接近于炭黑N660。采用10份裂解炭黑等量替代炭黑N660，对胶料的加工性能，物理性能等基本无影响，气密性略有提升，屈挠疲劳寿命略有延长；成品轮胎的高速性能、耐久性能均满足企业标准要求，且能降低配方成本。 |
| 英文摘要: |
| The application of pyrolysis carbon black in the inner liner of semi-steel radial tires was investigated.The results showed that the specific surface area and structural degree of pyrolysis carbon black were close to those of carbon black N660.When 10 phr pyrolysis carbon black was used as an equivalent replacement for carbon black N660，there was essentially no impact on the processing and physical properties of the compound，while the air tightness was slightly improved，and the flex fatigue life was slightly extended.Both the high-speed performance and durability of the tire met the enterprise standards，and the cost of the formula was reduced. |
