| 中文摘要: |
| 研究了白炭黑的品种、偶联剂用量和处理方法对白炭黑补强EPDM胶料静态和动态性能的影响；使用扫描电子显微镜分析了磨耗表面的形态及其与强伸性能间的关系；探讨了偶联剂改性白炭黑的作用机理与历程；使用经改造的压缩疲劳试验机测试了橡胶试样在动态下的心部温度。结果表明：白炭黑补强EPDM胶料的各项性能均远低于炭黑补强EPDM胶料，不同品种白炭黑的补强效果差别较大；使用偶联剂Si69处理白炭黑，可显著改善胶料的各项性能，偶联剂用量及改性方法对改性效果有重要影响。 |
| 英文摘要: |
| The influence of the silica kind，level and surface treatment as well as the level of silane coupling agent Si69 on the static and dynamic properties of silica-reinforced EPDM was studied；the abrasion surface from Akron test was analysed with SEM and the relationship between the abrasion surface morphology and the tensile properties was described；the mechanism and process of the silica modification with silane coupling
agent were discussed；and the temperature in the core of rubber test piece under dynamic condition was measured with improved Goodrich compression fatigue tester.The results showed that the properties of the silica-reinforced EPDM compound were much lower than those carbon black-reinforced EPDM compound；the reinforcing effects of different silica kinds were quite different；the properties of the silica-reinforcing EPDM compound
were significantly improved when the silica was treated with silane coupling agent Si69，and the modifying effect was remarkably influenced by the coupling agent level and the modification method. |
