Abstract

PURPOSE: To obtain a rubber compsn. for tire tread, which is low in rolling resistance and has high wet damping performance, by a method wherein carbon black is blended with a specified rubber blend, the mixture is kneaded without the addition of a vulcanizing agent, and the kneaded material is discharged from a mixer at an elevated temperature.
CONSTITUTION: 40W70pts.wt. carbon black is added to 100pts.wt. rubber component consisting of 25W75pts.wt. polybutadiene rubber (A)[which is substantially amorphous and contains 1,2-bond units of 65W90mol%] and 75W25pts.wt. natural rubber and/or polyisoprene rubber (B)[not more than 40wt% of which may be replaced by other conjugated diene rubber.] The mixture is kneaded in a mixer such as an internal mixer and discharged from the mixer at 170°C or higher. Then a vulcanizing agent and a vulcanizing accelerator are added to the discharged kneaded mixture and the mixture is vulcanized by a conventional method to produce the desired rubber compsn. for tire tread.
