RUBBER COMPOSITION FOR TIRE TREAD CAPABLE OF SATISFYING HIGH PERFORMANCE AND ENVIRONMENT-FRIENDLY PROPERTY AND AIR INJECTION TIRE USING THE SAME

摘要

PURPOSE: A rubber composition for tire tread is provided to improve braking and wear performance while maintaining fuel efficiency through use and ratio change of a styrene butadiene rubber. ;CONSTITUTION: A rubber composition for tire tread comprises, based on 100 parts by weight of a crude rubber, 4-10 parts by weight of softening agent, 40-100 parts by weight of filler, 1.5-2.0 parts by weight of vulcanizing agent, and 0.1-0.3 parts by weight of rubber accelerator. The crude rubber comprises 32-42 parts by weight of styrene-butadiene B rubber(S-SBR B), 72-82 parts by weight of styrene-butadiene D rubber(S-SBR D), and 18-28 parts by weight of butadiene rubber(BR B).;COPYRIGHT KIPO 2011
