| 中文摘要: |
| 研究涂覆式刺扎自密封轮胎涂层对轮胎室内高速和耐久性能、滚动阻力、噪声、均匀性、动平衡和静态气密性等相关性能的影响。结果表明：涂层对涂覆式刺扎自密封轮胎的室内高速性能、耐久性能、滚动阻力和均匀性影响不大；轮胎室内噪声有所增大，静不平衡量影响不一；在常温状态下，扎钉后能够较好地保持轮胎气密性，在低温状态下，扎钉后及时拔出，轮胎自密封性能较好，如钉子长时间停留在胎内，拔出后会出现不能自密封的现象。 |
| 英文摘要: |
| The effects of coated puncture self-sealing tire coating on tire indoor high-speed and durability performance，rolling resistance，noise，uniformity，dynamic balance and static air tightness were studied.The results showed that the coating had little effect on the indoor high-speed performance，durability，rolling resistance and uniformity of the coated puncture self-sealing tire.The indoor noise of the tire had increased，and the static unbalance had different effects.In the normal temperature state，the airtightness of the tire could be maintained after the nails were inserted.In the low temperature state，the tires had better self-sealing performance after the nails were pulled out in time.If the nails stayed in the tire for a long time，it will not self-seal after being pulled out. |
