MASTER BATCH COMPRISING YTTRIA-STABILIZED ZIRCONIA PARTICLE AND TIRE TREAD RUBBER COMPOSITIONS THEREOF AND TIRE USING THE SAME

摘要

The present invention relates to a rubber composition for a tire tread, comprising a masterbatch having improved heat resistance and corrosion-resistant performance, and a tire using the same. The rubber composition for a tire tread improves general properties accompanied when applying silica and improves electrical conductivity, by applying a masterbatch comprising yttria-stabilized zirconia powder, which is raw material rubber and a solid electrolyte pellet, in conjunction with silica, which is a filler for reinforcement.
