促进剂NS在轮胎胎面胶中的应用

Application of acclerator NS in tire tread compound

试验研究以促进剂NS减量替代促进剂NOBS在轮胎胎面胶中的应用效果。结果表明,以0.8份促进剂NS替代1份促进剂NOBS,胶料的ML和MH增大,t10和t90缩短;硫化胶的300%定伸应力和撕裂强度增大,阿克隆磨耗量减小;成品轮胎的速度性能提高,耐久性能达到企业标准要求,且生产成本略有下降。

The replacement of the accelerator NOBS by less-weight NS in the tire tread compound was experimentally investigated. The results showed that ML and M. increased,and t10 and t90 reduced by adding 0.8 phr NS instead of 1 phr NOBS in the tread compound;the modulus at 300% and tear strength of vulcanizate increased.and the Akron abrasion loss decreased;and the speed performance of finished tire improved.the endurance met the requirement of the enterprise standard,and the production cost somewhat decreased.
