| 中文摘要: |
| 研究氧化锌与活性氧化锌对汽车发动机悬置胶料及成品性能的影响。结果表明：与氧化锌胶料相比，等量活性氧化锌胶料的t10和t90缩短，抗硫化返原性能提高，定伸应力和拉伸强度降低，拉断伸长率和压缩永久变形增大，撕裂强度和耐热老化性能提高；随着活性氧化锌用量减小，活性氧化锌胶料的交联密度、抗硫化返原性能和物理性能降低；与采用氧化锌胶料的发动机悬置相比，采用活性氧化锌胶料的发动机悬置生产效率较高，减震性能稍差，高温耐久性能相当。 |
| 英文摘要: |
| The effects of zinc oxide and active zinc oxide on the properties of the rubber compound for automobile engine mount and the performance of the finished product of engine mount were investigated. The results showed that，compared with the compound containing zinc oxide，the compound containing the same amount active zinc oxide possessed shorter t10 and t90，improved anti-reversion property，reduced modulus and tensile strength，increased elongation at break and permanent set，higher tear strength and better heat aging resistance. It was found that，when the amount of active zinc oxide decreased，the crosslink density of the compound decreased，the anti-reversion property and physical properties decreased. Moreover，when active zinc oxide was used，the production efficiency of the finished engine mount was higher，the vibration reduction performance was slightly lower，and the durability at high temperature was kept at the same level. |
