Abstract

Nanocomposites based on an SBR/ENR50 rubber blend with the blend ratio of 50.50 using Cloisite 15A NANOCLAY (5 and 10 phr)) and CARBON BLACK (20 phr) were prepared by melt mixing process. The rubber compounds were crosslinked by ELECTRON BEAM irradiation process at 50 and 100 kGy doses. A reference sample containing CARBON BLACK at 35 phr was prepared using a conventional sulphur curing system. The gel content of the samples was specified using gel fraction measurement. The results showed the maximum gel content for the sample having 5 phr NANOCLAY and 20 phr CARBON BLACK. The dynamic mechanical properties, including the storage modulus, loss modulus, and loss factor, of the nanocomposites were evaluated using dynamic mechanical analysis (DMA) tests. The results indicated that, in spite of a well dispersed NANOCLAY in samples containing 10 phr NANOCLAY and 20 phr CARBON BLACK, a minimum loss factor was observed in the sample containing 5 phr NANOCLAY and 20 phr CARBON BLACK at 100 kGy. On the other hand, the storage modulus of the reference sample was found to be higher than that of the sample with 5 phr NANOCLAY and 20 phr CARBON BLACK. The mechanical properties, including the tensile strength, stress at 100%, 200%, and 300% elongation and the percentage of elongation were measured by a tensile machine. The results showed an increase in tensile strength and the stress at different elongations for a sample with 5 phr NANOCLAY and 20 phr CARBON BLACK compared to the reference sample. In the corresponding SEM images of the samples having NANOCLAY and CARBON BLACK irradiated at 100 kGy a significantly higher surface roughness was observed.
