轿车子午线轮胎带束层胶高硫黄-钴盐粘合体系的研究

Study on high sulfur-cobalt salt adhesion system in belt compound of PCR tire

研究高硫黄-钴盐粘合体系在轿车子午线轮胎带束层胶中的应用。试验结果表明,在轿车子午线轮胎带束层胶中采用高硫黄-钴盐粘合体系,可以提高硫化胶的200%和300%定伸应力及拉伸强度,保持硫化胶与钢丝帘线的粘合性能,提高硫化胶的动态力学性能及成品轮胎的高速性能和耐久性能,降低生产成本,改善作业环境。

The application of high sulfur-cobalt salt adhesion system in the belt compound of PCR tire was investigated. The results showed that, by using high sulfur-cobalt salt adhesion system in the belt compound of PCR tire, the modulus at 200% and 300% elongation and tensile strength of vulcanizate were increased,the adhesion property between vulcanizate and steel cord was kept,the dy- namic property of vulcanizate was improved, the high-speed performance and endurance of finished tire were improved ,the production cost was reduced, and the working environment was improved.
