A research has been carried out to develop natural rubber (NR) hybrid composites reinforced with marble sludge (MS)/Silica and MS/rice husk derived silica (RHS). The primary aim of this development is to scrutinize the cure characteristics, mechanical and swelling properties of such hybrid composite. The use of both industrial and agricultural waste such as marble sludge and rice husk derived silica has the primary advantage of being eco-friendly, low cost and easily available as compared to other expensive fillers. The results from this study showed that the performance of NR hybrid composites with MS/Silica and MS/RHS as fillers is extremely better in mechanical and swelling properties as compared with the case where MS used as single filler. The study suggests that the use of recently developed silica and marble sludge as industrial and agricultural waste is accomplished to provide a probable cost effective, industrially prospective, and attractive replacement to the in general purpose used fillers like china clay, calcium carbonate, and talc.
开展了一项研究，旨在开发由大理石污泥（MS）/二氧化硅和 MS/稻壳衍生二氧化硅（RHS）增强的天然橡胶（NR）混合复合材料。这种混合复合材料的开发主要目的是研究其固化特性、机械性能和溶胀性能。与其他昂贵的填充剂相比，使用大理石污泥和稻壳衍生二氧化硅等工业和农业废物具有环保、低成本和易于获得的主要优势。本研究结果表明，与仅使用 MS 作为单一填充剂的情况相比，MS/Silica 和 MS/RHS 作为填充剂的 NR 混合复合材料在机械和溶胀性能方面的性能要好得多。研究表明，使用最近开发的二氧化硅和大理石污泥作为工业和农业废物，可以提供一种具有成本效益、工业前景和吸引力的替代方案，替代通常使用的填料，如高岭土、碳酸钙和滑石。
