The invention relates to the technical field of rubber, and discloses rubber processing modified masterbatch for a tire tread, tire tread rubber and a preparation method of the rubber processing modified masterbatch. The rubber processing modified masterbatch contains a modifier, benzoyl peroxide, a matrix material, aromatic hydrocarbon oil and white oil, wherein the base material is solution polymerization type styrene-butadiene rubber and/or ethylene-vinyl acetate copolymer. According to the invention, the compatibility and dispersity of maleic acid series monomers in a high-viscosity rubber matrix can be improved, the odor of the modifier is reduced, and the modifier is environment-friendly.
本发明涉及橡胶技术领域,公开了一种轮胎胎面用橡胶加工改性母胶和轮胎胎面胶及其制备方法。所述橡胶加工改性母胶含有改性剂、过氧化苯甲酰、基体材料、芳烃油和白油;其中,所述基体材料为溶液聚合型苯乙烯‑丁二烯橡胶和/或乙烯‑醋酸乙烯酯共聚物。本发明能够改善马来酸系单体在高粘度橡胶基体相容性和分散性,降低改性剂气味,且对环境友好。
