RUBBER COMPOSITION FOR TIRE TREAD, METHOD FOR MANUFACTURING THE SAME AND TIRE MANUFACTURED BY USING THE SAME

摘要

The present invention relates to a rubber composition for a tire tread, a method for manufacturing the same and a tire manufactured by using the same, and the manufacturing method of the rubber composition for a tire tread comprises a first step of adding 5-20 wt% of silica, 40-60 wt% of carbon black and 3-6 wt% of Penta-methoxymethyl melamine in 100 wt% of a rubber material and mixing; and a second step of adding 1-2 wt% of a curing agent, 2-5 wt% of a curing accelerating agent and 1-5 wt% of zinc oxide in 100 wt% of the rubber material and curing. The rubber composition for a tire tread has excellent tensile strength and tear strength at the same time wherein chip cut resistance and heat resistance are excellent at the same time.
