摘要
对现用跑气保用轮胎胎侧支撑胶配方进行优化。结果表明:在天然橡胶/顺丁橡胶(BR)生胶体系中加入热塑性弹性体,并减小BR和炭黑N550用量,胶料的门尼焦烧时间和正硫化时间延长,抗硫化返原性能提高,工艺性能良好;硫化胶的物理性能和耐老化性能提高,生热降低;成品轮胎的耐久性能提高。
The existing formulation of the sidewall support compound for run-flat tire was optimized. The results showed that,by adding thermoplastic elastomer in the NR/BR blend,and decreasing the addition levels of BR and carbon black N550,the Mooney scorching time and optimum curing time of the compound were extended,the anti-reversion property was improved,and the processability was good. The physical properties and aging resistance of the vulcanizate were improved,and the heat build-up was decreased. The endurance of the finished tire was improved.
