| 中文摘要: |
| 研究了大比表面积活性氧化锌在轮胎肩垫胶中的应用效果。试验结果表明，用5份大比表面积活性氧化锌替代8份普通氧化锌，胶料的门尼粘度略有下降，焦烧时间和t10稍有延长，t90缩短;硫化胶的邵尔A型硬度、拉伸强度、300%定伸应力和撕裂强度均有所提高，而扯断伸长率和固特里奇生热有所降低;采用试验配方生产的轮胎成品性能明显提高，且配方成本下降。 |
| 英文摘要: |
| The application of the active zinc oxide with large specific surface to the shoulder pad was investigated. The results of test compound using 5 phr of active zinc oxide with large specific surface instead of 8 phr of conventional zinc oxide showed that the Mooney viscosity decreased a little,the scorch time and t10 increased a little，t90 reduced;the shore A hardness,tensile strength,300%modulus and tear strength of vulcanizate increased,and the elongation at break and Goodrich heat build-up decreased;the performance of finished tire using test compound improved significantly,and the formula cost decreased. |
