Abstract

Currently, the incorporation of ground cellulosic bagasse as a supplement reinforcing filler in rubber composites is considered to be one of the favorite means that could potentially assist in avoiding the utmost problematic environmental pollution due to the ashes left after burning of agricultural wastes. In addition, it may act in reducing the cost simultaneously with preserving the rubber vulcanizates physico-mechanical properties. In this study, a systematic work was implemented by preparing a series of mixes based on fixed concentration of 25 phr from natural ground bagasse powder (GBP) on a two roll mill to investigate the effect of different quantities (0 – 80 phr) of fumed silica (Si) on the cure characteristics, physical and mechanical properties of Bagasse-Styrene Butadiene Rubber (B-SBR) composites. A grinding machine was used, to obtain GBP with a selective grain size distribution ranging from about 20-180 µm. As well, the interfacial adhesion between SBR and bagasse was improved by adding 2.5 phr of maleic anhydride (MA), as a compatibilizer. It was obvious that values for both tensile strength and modulus at 100% elongation have recorded a significant increase with the increase in Si addition till reaching an optimum concentration of 60 phr, and then a gradual decrease in values takes place with further Si addition. Similarly, hardness recorded a gradual increase in values with the increase in Si content. On the other side the abrasion loss and degree of swelling values are enhanced by showing a marked decrease in values with the increase in silica content. It was evident that modified SBR brings well physico-mechanical properties and wear resistance. Thereby, it’s worth derived that the overall performance of Si filled SBR composites is well preserved in the presence of bagasse powder. The prepared modified SBR composite samples were also characterized by scanning electron microscope (SEM), which reveals a behavior confirming the improved mechanical properties.
