| 中文摘要: |
| 将硅铝炭黑(SAC)进行活化改性制成活性硅铝炭黑(ASAC)，并对SAC和ASAC填充NR和SBR胶料的硫化特性、物理性能及流变性能进行研究。结果表明，ASAC能明显改善SAC的延迟硫化效应，提高填充胶料的力学性能；ASAC在NR中的填充补强效果接近半补强炭黑，在SBR中的填充补强效果略优于优质陶土；ASAC填充NR胶料的流动性好，挤出胀大效应与填充半补强炭黑胶料相近。 |
| 英文摘要: |
| The activated silica-alumina carbon black (ASAC) was prepared by modifying the silica-alumina carbon black (SAC).The curing behaviour，physical properties and rheological properties of NR and SBR compounds respectively filled with SAC and ASAC were investigated.The results showed that the delayed vulcanization and the mechanical properties improved when ASAC was used in rubber compound instead of SAC；the reinforcing effect of ASAC was similar to that of semi-reinforcing carbon black in NR compound，and somew hat better than that of quality clay in SBR compound；ASAC-filled NR compound possessed good flow property and similar die swell to that of semi-reinforcing carbon black-filled compound. |
