Filler is one of the major additives in rubber compounds to enhance the physical properties. Even though numerous benefits obtained from agricultural by products like coconut shell, rice husk etc., still they constitute a large source of environmental pollution. In this investigation, one of the agricultural bye product coconut shell powder (CSP) is used as filler in the compounding KNB rubber. It shows the positive and satisfied result was achieved only by the use of filler Fast Extrusion Furnace (FEF) and coconut shell powder (CSP) which was used 50% in each. The effect of these fillers on the mechanical properties of a rubber material at various loading raging from 0 to 60PHP was studied. Mercaptodibanzothiazole disulphide (MBTS) was used as an accelerator. The result shows that presence of 25% and 50% of the composites has better mechanical properties like Hardness, Tensile strength, Elongation at break and Specific gravity when compared with other two combinations. Even though both 25% and 50% of composites shows good mechanical properties, 50% of CSP have more efficient than 25% of CSP.
填料是橡胶混合物中用于增强物理性能的主要添加剂之一。尽管从椰子壳、稻壳等农业副产品中可获得诸多益处，但它们仍是环境污染的一大来源。在本研究中，农业副产品之一的椰子壳粉（CSP）被用作KNB橡胶混炼中的填料。结果表明，仅通过使用快速挤出炉炭黑（FEF）和椰子壳粉（CSP）（各占50%）取得了积极且令人满意的结果。研究了这些填料在0至60份/100份橡胶（PHP）的不同用量下对橡胶材料机械性能的影响。二硫化二巯基苯并噻唑（MBTS）用作促进剂。结果表明，与其他两种组合相比，含25%和50%复合材料的硬度、拉伸强度、断裂伸长率和比重等机械性能更佳。尽管25%和50%的复合材料均表现出良好的机械性能，但50%的椰子壳粉比25%的椰子壳粉效率更高。
