| Abstract: |
| The effect of modified silica and silicone powder on the properties of SBR compound was investigated. The resultsshowed that，at the same total amount of fillers，as the addition level of silicone powder increased， the MLand MH 0f the compound decreased，the physical properties of the vulcanizates decreased，and the resilience and wear resistance were improved. Compared with the SBR vulcanizate filled with unmodified fillers，the modulus，tensile strength and elongation at break of the SBR vulcanizate filled with fillers modified by silane coupling agent KH-550 0r M-CNSL increased，the tearstrength changed little，and the resilience and wear resistance were improved. It was found that the modification effect of M-CNSL was better. SEM test results indicated that，with modification，the dispersion of silica and silicone powder in the SBR vulcanizate was improved. |
