Utilization study on red brick waste as novel reinforcing and economical filler for acrylonitrile butadiene rubber composite

Abstract Red brick waste (RBW) powder was used as a reinforcing filler for acrylonitrile butadiene rubber (NBR) preparing eco-friendly composites. The main constituent of this is silica which considered to be one the traditional fillers in industry. So it worthwhile get suitable manner by using NBR. Physicomechanical properties were evaluated, including tensile strength, elongation at break, hardness shore A, and change mechanical after thermal-oxidative aging seven days 90 °C. In addition, equilibrium swelling toluene prepared composites also included. Moreover, cross-linking density measured according Flory Rehner's equation. From physicomechanical measurements, observed that strength (shore A) increased with increasing content because red filler's stiffness. contrast, break degree decreased content. morphology polymeric monitored scanning electron microscope reflects uniform distribution inside NBR matrix. electrical magnetic NBR/RBW evaluated. measurements revealed values ?? increase while ?'' decreases dc conductivity ? lie order 10 –11 S/cm. This finding recommends such could insulation antistatic applications. show superparamagnetic behavior Therefore, obtained electromagnetic based on measurements. Graphical
