Problems solved by technology

The various performances of tires tend to decrease when one performance is improved, so it is generally believed that if rubber with a low glass transition temperature (Tg) is used, the wear resistance and low fuel consumption of the tire can be improved, but the safety ( braking) will reduce

Abstract

The invention relates to a rubber composition for a tire tread and a tire manufactured using the same, and provides a rubber composition for a tire tread which comprises 100 parts by weight of rubber raw materials containing emulsion polymerized styrene-butadiene rubber, 7-13 parts by weight of environmental friendly softeners, 73-79 parts by weight of fillers, 1.6-1.9 parts by weight of vulcanizing agents, and 0.15-0.25 parts by weight of thiuram vulcanization accelerators. The rubber composition for a tire tread minimizes the release amounts of polycyclic aromatic hydrocarbons (PAH) and nitrosamines, so the composition not only is environmental friendly but also has excellent low fuel consumption, braking performance, and abrasion resistance.

Description

technical field [0001] The present invention relates to a rubber composition for tire treads and tires manufactured therefrom, and in particular to minimizing the release of polycyclic aromatic hydrocarbons and nitrosamines, thereby being environmentally friendly and having excellent fuel consumption, braking performance and durability. Abrasive rubber composition for tire tread and tire manufactured therefrom. Background technique [0002] Recently, along with the demand for higher performance of cars, consumers also demand higher performance for tires, and in particular, consumers demand tires that have both safety (braking performance) and low fuel consumption. The various performances of tires tend to decrease when one performance is improved, so it is generally believed that if rubber with a low glass transition temperature (Tg) is used, the wear resistance and low fuel consumption of the tire can be improved, but the safety ( braking) will be reduced instead.
