| 中文摘要: |
| 将间苯二甲酰肼（IDH）母胶CSC920用于绿色轮胎胎面胶中，研究IDH对绿色轮胎胎面胶性能的影响。结果表明：与未添加IDH母胶CSC920的混炼胶相比，添加IDH母胶CSC920的混炼胶的Payne效应明显降低，硫化速度加快，焦烧时间缩短；硫化胶的交联密度增大，定伸应力、拉伸强度和耐屈挠疲劳性能提高，拉断伸长率、撕裂强度和耐磨性能降低，损耗因子减小，压缩生热和活化能下降，老化后耐磨性能以及拉伸强度、拉断伸长率和撕裂强度保持率提高。 |
| 英文摘要: |
| 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. |
