| 中文摘要: |
| 研究纳米氧化锌在工程机械轮胎胎面上层胶和缓冲层胶中的应用。结果表明：采用纳米氧化锌70%替代普通氧化锌，胶料的硫化时间延迟，密度减小；硫化胶的定伸应力、拉伸强度、撕裂强度和回弹值增大，耐磨性和耐老化性能提高，生热降低；成品轮胎的物理性能和粘合性能提高。 |
| 英文摘要: |
| The application of nano zinc oxide in the upper layer tread compound and breaker ply compound of off-the-road tire was investigated.The results showed that，by using nano zinc oxide to replace 70% of ordinary zinc oxide，the curing time of the compound was delayed and the density was reduced.The modulus，tensile strength，tear strength and resilience of the vulcanizate increased，the wear resistance and aging resistance were improved，and the heat build-up decreased.The physical properties and adhesion property of finished tire were improved. |
