轮胎老化耐久性能的研究

Overview of Research on Tire Aging Endurance

介绍轮胎老化耐久性能研究历程,指出化学老化是轮胎失效的主要原因,带束层和肩部是主要的损坏部位。分析烘箱老化试验条件如老化气体、老化温度、老化时间和填充气体补充对轮胎老化耐久性试验的影响。建议添加防老剂、用氮气作填充气体、改善内衬层气密性以提高轮胎老化耐久性能。

The research on tire aging endurance was introduced. It was pointed out that chemical aging was the main cause of tire aging failure,and the belt and shoulder of the tire were the main damaged parts.The effect of oven-aging test conditions such as aging gas,aging temperature,aging time and filled gas of tire on the aging endurance experiments was described. To improve the aging endurance of the tire,it was recommended to add antioxidant,use nitrogen as filled gas and improve the airtightness of the inner liner.
