| Abstract: |
| 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. |
