Abstract:
      In this paper, the dispersible nano silica was synthetised by liquid phase in-situ modification with KH570 as modifier. To investigate the effects of different amount of modifier on the mechanical properties, abrasion properties, rheological properties of the system of solution polymerization styrene butadiene rubber/butadiene rubber which modified with nano silica were tested. Fourier transform infrared spectroscopy showed that the silica surface had been successfully modified by the KH570 through the chemical bonds. SEM showed that the agglomeration was weakened and improved the dispersion. The mechanical properties of SSBR/BR/SiO2 nanocomposites were improved, the best modified quantity was 25-50mmol/Kg; wear resistance was improved obviously, especially when the amount of modifier was 50mmol/Kg, it had minimum wear volume, reduced by 33.85%; reduced the Payne effect, weakened the agglomeration of silica, and improved the dispersion in the rubber matrix.
