ABSTRACT
Nanocomposites were prepared by incorporating varying amounts of nanokaolin clay and vinyl silane grafted nanokaolin clay in NBR, on a two roll mill. Improvement in mechanical properties like tensile strength, elongation at break, modulus and tear strength were observed for the composites. Cure characteristics showed an increase in the cure rate of the composites.Clay rubber nanocomposites were characterized by X- ray diffraction (XRD) and scanning electron microscopy (SEM). The increase in d spacing suggested an intercalated /exfoliated structure of clay and SEM studies showed uniform dispersion of clay in the matrix. Swelling index decreased with the increase in filler loading, as observed from the swelling studies conducted in toluene. Rubber filler interactions were also studied by strain sweep analysis. It was found that the complex modulus values increased with the clay content indicating better rubber filler interaction.Differential scanning calorimetry (DSC) studies showed that glass trasition temperature (Tg) remained unchanged. Thermal studies showed that addition of clay marginally improved the thermal stability
