实施方式所涉及的轮胎胎侧胶部件的制造方法包括第一混炼工序和第二混炼工序,在第一混炼工序中,将二烯系橡胶、炭黑、由下式(I)表示的化合物(式中,R1、R2表示氢原子、烷基、烯基或炔基,M+表示Na+、K+、Li+)、以及氧化锌进行混炼,制作第一混炼物,在第二混炼工序中,向所述第一混炼物中添加蜡和/或硬脂酸进行混炼。由此,抑制抗撕裂性恶化,并且,提高低发热性。

    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.
