SWELLING RESISTANCE OF NANO POLYMER NANOCOMPOSITE

The ethylene-propylene-diene monomer/styrene-butadiene rubber (EPDM/SBR)-nanosilica (SiO2) nanocomposite was prepared. The 0–10 parts per hundred rubber (phr) of SiO2 with EPDM/SBR was mixed on a two-roll mill. The effect of nanosilica (0–10 phr) and silane coupling agent (bis(triethoxysilylpropyl)-tetrasulphide) (TESPT) on the curing characteristics mechanical properties rebound resilience compression characteristics abrasion swelling property and morphological characteristics of the EPDM/SBR-SiO2 nanocomposites was investigated and studied. From the results it was clear that the mechanical wear and swelling properties steps-up with increase in the content of nanosilica particles in it. The addition of TESPT enhances the properties of the nanocomposites to a greater extent. From the analysis it was clear that the effect of nanosilica concentration in the rubber composite with TESPT was found to be superior compared to nanocomposites without it.
