NANOCOMPOSITES OF NATURAL RUBBER AND METHOD OF MANUFACTURING THE SAME

摘要

This invention relates to a triple phase nanocomposite rubber with different composition of nanofillers thereof, namely alumina- zirconia nanocomposite toughened rubber, composed of dual phase nanosized filler comprised of zirconia reinforced alumina and an elastomer phase comprised of natural rubber containing dispersion therein of nanoparticles. Said dispersed nanoparticles may be oriented spatially in all directions within the rubber matrix. The rubber composition may contain nanofiller therewith various phr of rubber matrix. The said nanocomposite rubber is prepared by phase mixing process comprised of two-roll mixing of cis 1 -4 polyisoprene together with alumina-zirconia nanocomposite filler to form a pre-mix thereof, and thereafter mixing therewith said nanocomposite as a pre-formed blend of natural rubber and spatially dispersed nanocomposite particles.
