| Abstract: |
| The effects of silica dispersing agent HST and H60EF on the properties of methyl vinyl silicone rubber（MVQ）/styrene butadiene rubber（SBR） blend were studied.The results showed that，by adding silica dispersing agent HST and H60EF in the MVQ/SBR blend，the curing rate of compound increased，the dispersion，processability and mixing efficiency were improved.Silica dispersing agent HST had no obvious effect on the dynamic mechanical properties of MVQ/SBR blend，and could improve the tear strength and aging resistance.It could be used as a functional agent for MVQ/SBR blend. |
