Evaluation of Mechanical Properties of Wollastonite/SBR Composite

Abstract

The wollastonite with fibrous structure can be used as the filler in the composite. In this paper, the composite was prepared by incorporating the wollastonite into butadiene styrene rubber (SBR) matrix through the mechanical agitation and roll mixing technologies. Mechanical properties of SBR filled with different amount of wollastonite content were studied and compared. It was shown that the mechanical properties of SBR filled with wollastonite could be improved significantly. The tensile strength and elongation at break were increased with the increase of the wollastonite. The tensile strength could be enhanced from 4.1MPa to 5.0MPa, and the elongation at break from 389% to 572%.

The Effect of Carbon Ash on the Properties of Butadiene-Styrene Rubber (SBR) at Low Levels

“…However, due to its dependence on petroleum feedstock (for synthesis), the instability of price of petroleum has been resulted in increasing interest for other reinforcing fillers [1] . The reinforcing fillers from renewable resources into rubber materials have become of major interest in recent years, including the wollastonite [2,3] , rice husks [4][5][6] , oil palms [7] , fly ash [8] and chitin [9] . Carbon ash is a type of industrial dust originating from carbonization of polymers at high temperature.…”
