Study on the vulcanization and mechanical properties of Rubber nanocomposites filled with nano organoclay

The effects of nano filler amount on the vulcanization and mechanical properties of styrene butadiene rubber (SBR) nanocomposites were studied. It was found that with increase in nanoclay amount in composite the scorch and cure time decreased; and the rate of vulcanization increased.On the other word, the curing reaction was enhanced in the presence of nanoclay. Mechanical properties are also modified by adding nano filler to the polymeric matrix. With increasing nanoclay concentration, tensile strength, modulus and elongation at break increased
