| 中文摘要: |
| 研究纳米粘土在全丁苯橡胶（SBR）工程机械轮胎胎面胶中的应用。结果表明，由于粘土具有独特的片层结构，并且长径比较大，在基体中纳米分散，因此其独特的补强效应使其可以明显提高全SBR胶料的抗切割性能，同时使定伸应力稍下降、拉断伸长率提高、撕裂强度增大、疲劳裂纹增长速度变缓。轮胎成品道路试验表明，采用纳米粘土制造的工程机械轮胎胎面胶抗切割性能优异，使用寿命明显提高。 |
| 英文摘要: |
| The application of nano-clay in SBR tread for off-the-road tire was investigated.The results showed that，the clay could be nano-dispersed in the matrix due to its unique lamellar structure and large aspect ratio.The addition of nano-clay could increase the cutting and chipping resistance of SBR compound by its unique reinforcement effect. Moreover，the modulus decreased，the elongation at break and tear strength increased，and the crack growth was slowed down.It was found through the test of the finished tire that the cutting and chipping resistance of the tread for off-the-road tire by the addition of nano-dispersed clay was excellent，and the tire service life was extended significantly. |
