1Studies on Physical Chemistry of Rubber-Rice Husk Ash Composites显示文摘Nowadays an alternate source of filler from renewable and plant derivatives are being thought of in rubber industries due to their reliability,environmental and economic benefits.Rice Husk Ash(RHA)a byproduct of the rice milling industry is obtained on partial and as well as full combustion of the rice husks.This ash is a good source of silica,silicates and needle shaped carbon and hence can be used as filler for cements.In the present study,a detailed investigation was carried out to understand the RHA as reinforcing material using mechanical properties and fractography using SEM.The rubbers studied were natural rubber(NR),poly chloroprene(CR)and ethylene propylene diene monomer(EPDM).Interestingly,the RHA added NR stock on open mill mixing generated considerable amount of static charges.The properties of NR were found to be as good as regular formulations.EPDM compounds behaved well during mixing.But the properties were found to be poor.CR-RHA compounds were found to result in higher viscosity and the properties were not as good.The SEM studies showed surprisingly cohesive failure as evidenced with the presence of flow lines and the fibrous filler(RHA)remains embedded in the matrix regardless of the chemistry of the repeating unit,NR,EPDM and the chlorine containing monomer inCR.V.Subrahmanian M.Albert Noble Einstien 2019Journal of Renewable Materials2019,7,2:0
