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

Abstract

Carbon ash composed of mainly amorphous carbon and zinc oxide was used as the filler in the butadiene-styrene rubber (SBR) materials. In this paper, carbon ash was characterized by XRD. Furthermore, the composites were prepared by incorporating carbon ash into SBR matrix through the mechanical agitation and roll mixing technologies. Vulcanization characteristics and mechanical properties of SBR filled with carbon ash were investigated. The effect of coupling agent (KH550/KH570) on the mechanical properties was also discussed. The experimental results indicated that the tensile strength and modulus at 300% of SBR filled with carbon ash could be improved significantly.
