Abstract

Natural rubber has higher insulation properties. Filler can be added to reinforce the natural rubber. Good insulator composites of natural rubber are better with suitable reinforcement filler. Furthermore, there are many researches about nanocomposite and natural rubber based composite, but there is little research that combine the natural rubber and nanoparticles in fabricating the composites. Thus, this research was carried out to develop a DPNR reinforced SnO2 nanocomposite. The purpose of this study was to develop a nanocomposite composite system by incorporating SnO2 as the reinforcement nanofiller and DPNR as their matrix resin. The nanocomposite were produced by using a combination of meltblending technique and then followed by the hot compression process, to enhance the properties of produced composites. The selection of optimum composition of DPNR matrix resin are based on the SnO2 loading. Therefore, in this study, different loading of SnO2 (0 %, 0.5%. 1.0 %. 3.0 %, 7.0 %) were used to investigate the mechanical properties, physical properties and dielectric properties. Later, the surface morphology of the selected samples were analysed by scanning electron microscopy (SEM) observation. At the end of this study, good mechanical and dielectric properties were developed and proposed for insulation breakdown application. In addition, it was analysed that DPNR/SnO2 nanocomposite at 3.0 wt.% of filler loading has better insulation breakdown properties.
