| 中文摘要: |
| 研究成品胶料在高温下经过反复伸缩变形后的耐疲劳性能。结果发现：胶料中的杂质使其耐疲劳性能有潜在的不稳定因素；成品轮胎在使用中产生的早期损坏、同批产品质量不稳定与胶料中的杂质缺陷有密切关系；在实际生产中，原材料杂质、现场工艺和胶料运输过程需要严格控制把关，避免杂质进入胶料从而影响产品质量。 |
| 英文摘要: |
| The fatigue resistance of the finished tire compound after repeated stretching deformation at high temperature were studied.The results showed that there were potential unstable factors in the fatigue resistance because of the impurities.The early damage of the finished tire in use and the unstable quality of the same batch of products were closely related to the impurities in the compound.In the actual production，raw material impurities，on-site process and rubber transportation process needed to be strictly controlled to avoid impurities entering the compound，which would affect the product quality. |
