抗硫化返原剂在全钢载重子午线轮胎胎面胶中的应用

Application of Anti-reversion Agents in Tread Compound of Truck and Bus Radial Tire

研究抗硫化返原剂WK901,WY988和KA9188在全钢载重子午线轮胎胎面胶中的应用。结果表明:在胎面胶中加入抗硫化返原剂WK901,胶料的抗硫化返原性能和耐老化性能最好;加入抗硫化返原剂WY988和KA9188,胶料的定伸应力、弹性和耐疲劳性能提高,生热和滚动阻力降低。

The application of anti-reversion agent WK901,WY988 and KA9188 in the tread compound of truck and bus radial tire was investigated. The results showed that,by adding anti-reversion agent WK901 in the tread compound,the anti-reversion property and aging resistance of the compound were the best.By adding anti-reversion agent WY988 and KA9188,the modulus,elasticity and fatigue resistance of the compound were improved,while the heat build-up and rolling resistance decreased.
