Tread rubber compound comprising surface modified carbon black

摘要

The present invention relates to a tire tread rubber composition , and more particularly, solution polymerization styrene -butadiene rubber single component or solution polymerization -styrene butadiene rubber and 60 to 90 parts by weight of butadiene rubber is composed of 10 to 40 parts by weight of carbon black while the surface is modified by including 40 to 80 parts by weight of a conventional tread rubber composition containing silica prepared does not , and the modification by oxidizing the surface of carbon black on the silica and carbon black as a tire tread rubber composition causes the low fuel consumption property can be enhanced to a level equal to or higher .
