NANO ZINC OXIDE IMMOBILIZED NANOPOROUS SILICA COMPOSITE MATERIAL AND A RUBBER COMPOSITION COMPRISING THE SAME

摘要

The present invention relates to a nano zinc oxide immobilized nanoporous silica composite material and a rubber composition containing the same. By adding the nanoporous silica composite material to the rubber composition for tires for reinforcing, crosslinking efficiency and dispersing properties are improved, abrasion properties are remarkably improved compare to a case of adding regular nanoporous silica, the production costs for the tires are reduced by remakly reducing the usage of zinc oxide, and the exposure of heavy metal by the abrasion of the tires are reduced.
