摘要
研究轿车子午线轮胎胎面胶的配方。结果表明:在胎面胶配方中采用溶聚丁苯橡胶/天然橡胶并用胶和炭黑N375/白炭黑补强体系,并适当调整硫化体系,胶料的焦烧时间缩短,硫化胶的300%定伸应力、拉伸强度和撕裂强度减小,回弹值增大,压缩生热降低;成品轮胎的耐久和高速性能均达到国家标准要求,滚动阻力系数达到欧盟轮胎标签法规的C级要求。
The tread compound formulation of passenger car radial tire was investigated. The results showed that,by using solution polymerized styrene-butadiene rubber/natural rubber blend and carbon black N375/silica reinforcing system, and modifying curing system properly in the tread compound,the scorch time of the compound was reduced, the stress at 300% strain, tensile strength and tear strength of the vulcanizates decreased, the resilience increased, and the compression heat build-up decreased. The endurance and high speed performance of finished tire met the requirements of national standards,and the rolling resistance coefficient met the requirement of EU standards for C label.
