RUBBER COMPOSITION FOR TIRE BELT TOPPING AND TIRE MANUFACTURED BY USING THE SAME

摘要

The present invention relates to a rubber composition for tire belt topping and a tire manufactured by using the same which comprise the following: 100 parts by weight of material rubber; 30-80 parts by weight of carbon black; 1-20 parts by weight of silica; and 0.1-10 parts by weight of cobalt acetylacetonate. The rubber composition for belt topping improves modulus and is favorable for fatigue capacity.
