NR–SBR type rubber is filled with nanoclays at concentration of
1 wt.%, 2 wt.% and 3 wt.%. The clays filled rubber composites was
processed using Banbury mixer and observed an exfoliated
nanocomposite structure up to 2 wt.% clay and at 3 wt.% nanoclay
intercalated structure is obtained in the composite. Curing
characteristics of nanocomposites show that the 90% cure is
obtained in 12.68 min. Cure time continuously decreases as clay
concentration increase in the rubber matrix. Maximum reduction
in cure time is observed for 3 wt.% nanoclay of 9.71 min. The
improper balance among curing, curing time and concentration
have resulted in intercalated nanocomposite structure in 3 wt.%
nanoclay composites.
