This study has investigated the effect of magnetically modified natural zeolite on nanosilica-reinforced natural rubber composites. We use technical specifications rubber (TSR) SIR 20 with nanosilia reinforced fillers and Titanate coupling agent (TCA) as filler and elastomer binders. The results showed that nanosilica- zeolite-magnetite (Fe3O4) mixture had an influence on strength and stiffness and could be a substitute for Carbon Black. The relationship between crosslink density, mechanical properties and damping properties were explored. We also identified that improved properties were produced by modification of white oil softeners and fillers of nanosilica-zeolite-magnetite mixtures. The results of magnetically modified zeolite on nanosilica-reinforced natural rubber composites showed that crosslink density, mechanical properties and damping properties increased significantly. The damping ratio in Si + Fe + Z samples both with or without white oil is higher than other samples (?> 0.03). Based on these results, nanosilica fillers combine with magnetically modified zeolites and titanate coupling agent, potentially replacing carbon black and applicative for damping devices, as well as synthetic muscle replacement cadavers with a customized formula.
