The invention discloses a green and environment-friendly tread rubber. The tread rubber is prepared through the following steps: putting the following raw materials, by weight, 40-60 parts of bacon rubber, 30-40 parts of butadiene rubber, 20-30 parts of solution polymerized styrene-butadiene rubber and 5-6 parts of tread rubber powder into an open mill, plastifying to obtain plastified rubber; putting and mixing the plastified rubber, 20-30 parts of carbon black, 10-15 parts of white carbon black, 0.5-1.0 part of a white carbon black dispersing agent, 1.5-2.0 parts of a silane coupling agent,8-12 parts of titanium dioxide, 1.0-1.5 parts of stearic acid, 0.2-0.3 part of an anti-scorching agent, 2-3 parts of an anti-aging agent, 1.5-2.0 parts of microcrystalline wax, 0.1-0.5 part of an anti-reversion agent, 1.5-2.0 parts of polyvinyl alcohol and 1.0-3.0 parts of triisopropanolamine into a mixing mill; and adding insoluble sulfur, continuously mixing for 10 min, and discharging the rubber. The green and environment-friendly tread rubber provided by the invention can be used for preparing an environment-friendly radial tire with low rolling resistance.
