| Abstract: | Mullite filled styrene-butadiene rubber(SBR) composites were prepared on a two-roll mill with untreated or treated mullite(by mass fraction of 3% A-189) as fillers. The effects of these fillers on properties of filled SBR at various loadings were investigated, and the comparison was conducted with those of SBR filled with precipitated silica. The results showed that mullite was a semi-reinforcing filler for SBR and the mullite filled SBR exhibited better overall cure properties, lower Mooney viscosity, lower permanent set, better resilience as compared to those of precipitated silica filled ones, while other properties were inferior to those of precipitated silica filled ones, especially with regard to tensile strength, tear strength and abrasion resistance. The presence of the silane coupling agent could enhance the mechanical properties of mullite filled SBR vulcanizates. |
