| Abstract: |
| The effect of isophthalic dihydrazide（IDH）on the properties of the green tire tread compound was studied by using IDH master compound CSC920.The results showed that，compared with the compound without IDH masterbatch CSC920，the Payne effect of the compound with CSC920 was significantly reduced，the curing speed was accelerated，and the scorch time was shortened.For the compound with CSC920，the crosslinking density，modulus，tensile strength and flexural fatigue resistance of the vulcanizate increased，the elongation at break，tear strength and wear resistance decreased，the loss factor，compression heat generation and the activation energy were reduced，the wear resistance and the retention rates of tensile strength，elongation at break and tear strength after aging were improved. |
