Application of Single-layer Inner Liner Structure in Passenger Car Radial Tire

研究单层内衬层结构在轿车子午线轮胎中的应用。结果表明:与传统的双层内衬层结构设计相比,单层内衬层的挤出、成型及硫化生产工艺稳定,成品轮胎的充气外缘尺寸、强度、脱圈阻力、高速性能和耐久性能相当,滚动阻力略有减小,气密性略有降低,满足轮胎使用要求,同时可减小轮胎质量,节约生产成本。

The application of the single-layer inner liner structure in passenger car radial tires was studied.The results showed that compared with the traditional design of the double-layer inner liner structure,the extrusion,building and vulcanization production process of the single-layer inner liner was stable,the inflated peripheral dimension,strength,bead unseating resistance,high-speed performance and durability of the finished tire were equivalent,the rolling resistance decreased slightly,but the air tightness was slightly reduced.The designed single-layer inner liner met the requirements of tire applications with reduced tire weight and production cost.
