The processing in addition to characterization of carboxylated nitrile butadiene rubber based nanocomposites is presented in this work. The outcome of nanoclay (NC) in black filled compounds is tinted. 20phr carbon black was used as standard in the entire studies while the nanoclay loading was varied from 2.5 to 10phr. The effect of nanoclay loading on the cure properties of XNBR was studies by using Moving Die Rheometer (MDR). The studies showed that the adding up of nanoclay significantly affected the scorch time and cure time of the rubber nanocomposites. The storage stability of the rubber composites were moreover characterised using rheometer. The effect of curing temperature on the physical properties of the rubber nanocomposites were studied by curing the rubber compound at 140°C, 150°C, and 160°C. XRD and TEM studies were carried out for characterising the morphology of the rubber nanocomposites. The microstructure showed a mixture of intercalated and exfoliated clay structure in rubber matrix. The rubber nanocomposites were characterised for the mechanical properties including tensile strength, elongation at break, abrasion resistance, and dynamic mechanical properties. The studies showed that the tensile strength showed an increase of 62% compared to that XNBR with only 20phr carbon black at lower loading of nanoclay which further decreased at higher loading of NC. However, the dynamic modulus showed a steady increase with increase in NC loading.
