半钢子午线轮胎胎体帘布胶配方优化

Formulation Optimization of Carcass Ply Compound for Steel-belted Radial Tire

优化半钢子午线轮胎胎体帘布胶配方。结果表明:在半钢子午线轮胎胎体帘布胶配方中增大合成橡胶用量,并添加少量白炭黑,胶料的拉伸性能、抗硫化返原性能和耐热老化性能提高,H抽出力增大,生产成本降低;成品轮胎的高速性能相当,耐久性能提高。

The formulation of the carcass ply compound for steel-belted radial tire was optimized.The results showed that,by increasing the amount of synthetic rubber and adding a small amount of silica in the formula,the tensile properties,reversion resistance and heat aging resistance of the compound were improved,H pull-out force increased,and the cost was reduced. The finished tire with the optimized carcass ply compound showed good high-speed performance and improved durability.
