矿用工程机械轮胎缓冲层胶的配方优化

Optimization of Buffer Layer Compound for Off-The-Road Mining Tire

对矿用工程机械轮胎缓冲层胶配方进行优化。结果表明:通过调整缓冲层胶配方补强体系和硫化体系,采用间-甲-白粘合体系,胶料的门尼粘度降低;硫化胶的物理性能和耐热老化性能提高;成品轮胎的耐久性能提高,脱层现象减少,使用寿命延长。

In the study,the buffer layer compound of off-the-road mining tire was optimized. The results showed that,by adjusting the reinforcing system and curing system,and using resorcinol-formaldehydesilica adhesion system,the Mooney viscosity of the compound was reduced,physical properties and heat aging resistance of the vulcanizates were improved,durability of the finished tire was improved,delamination defect was reduced,and service life was extended.
