Document Type and Number:
WIPO Patent Application WO/2018/070249
Kind Code:
A1
Abstract:
A method for producing a tire sidewall rubber member according to an embodiment comprises: a first kneading step for producing a first kneaded product by kneading a diene-based rubber, carbon black, a compound represented by formula (I) (wherein R1 and R2 each represent a hydrogen atom, an alkyl group, an alkenyl group or an alkynyl group, and M+ is Na+, K+ or Li+), and zinc oxide; and a second kneading step for adding a wax and/or stearic acid to said first kneaded product and kneading the same. Thus, low heat-generating properties are improved while suppressing the deterioration of tear resistance.
