| 中文摘要: |
| 研究补强体系对天然橡胶减振材料性能的影响。结果表明：填充19份炭黑N774和39份白炭黑的胶料的拉伸强度、拉断伸长率和撕裂强度最大，但填料分散性和耐老化性能差，压缩永久变形较大；填充37份炭黑N550和19份炭黑N774胶料的交联密度和拉伸强度最小，Payne效应强，压缩永久变形最大；填充43份炭黑N774或39份炭黑N660及20份白炭黑的胶料兼具优异的填料分散性和耐老化性能，且压缩永久变形较小，可满足减振橡胶材料的性能要求。 |
| 英文摘要: |
| The effect of reinforcement systems on the performance of natural rubber（NR） damping materials was studied.The results showed that，the vulcanizate filled with 19 phr carbon black N774 and 39 phr silica had the highest tensile strength，elongation at break and tear strength，but the filler dispersion and aging resistance were poor，and the compression set was relatively large.The crosslinking density and tensile strength of vulcanizate filled with 37 phr carbon black N550 and 19 phr carbon black N774 were the lowest，with strong Payne effect and maximum compression set.The vulcanizates filled with 43 phr carbon black N774 or 39 phr carbon black N660 and 20 phr silica had excellent filler dispersion and aging resistance，and had small compression set，it could meet the performance requirements of damping rubber materials. |
