| Abstract: |
| 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. |
