| 中文摘要: |
| 开发一种低滚动阻力半钢子午线轮胎胎体配方。结果表明：采用大粒径、低结构度的炭黑N660替代炭黑N330，采用低玻璃化温度锡偶联的溶聚丁苯橡胶替代乳聚丁苯橡胶，同时调整橡胶操作油和硫黄用量后，胶料的硫化特性变化不大、硬度和定伸应力相当、拉伸性能和粘合性能略差；胶料60 ℃的损耗因子明显减小，成品轮胎的高速和耐久性能接近，滚动阻力降低4.56%，可节省汽车油耗。 |
| 英文摘要: |
| A carcass formulation of low rolling resistance steel-belted radial tire was developed.The results showed that，when carbon black N660 with large particle size and low structure degree was used to replace carbon black N330，and solution polymerized styrene butadiene rubber with low glass transition temperature tin coupling was used to replace emulsion polymerized styrene butadiene rubber，the curing characteristic of the compound changed little，the hardness and modulus were equivalent，and the tensile properties and adhesion properties were slightly poor after adjusting the amount of rubber operating oil and sulfur.The loss factor of compound at 60 ℃ was reduced obviously.The high speed performance and durability of finished tire were close，and the rolling resistance was reduced by 4.56%，which could save the automobile fuel. |
