The invention relates to the field of rubber, and discloses a rubber processing modified master batch for tire treads, vulcanized rubber and a preparation method and application thereof, and the rubber processing modified master batch comprises maleic acid series monomers, benzoyl peroxide, solution polymerized styrene-butadiene rubber and white oil; wherein the content of the solution polymerized styrene-butadiene rubber is 30-60 parts by weight, the content of the maleic acid series monomer is 40-60 parts by weight, the content of the benzoyl peroxide is 5-12 parts by weight, and the content of the white oil is 5-10 parts by weight. The rubber processing modified master batch provided by the invention can improve the compatibility and dispersity of maleic acid series monomers in a high-viscosity rubber matrix, so that the strength of tire tread rubber can be better improved, the heat generation of the tire tread rubber is reduced, the wet skid resistance is improved, the rolling resistance is reduced, and the energy consumption in the mixing process is reduced.

    本发明涉及橡胶领域,公开了一种轮胎胎面用橡胶加工改性母胶与硫化橡胶及其制备方法与应用,其中,所述橡胶加工改性母胶包含马来酸系单体、过氧化苯甲酰、溶聚丁苯橡胶和白油;其中,溶聚丁苯橡胶的含量为30‑60重量份,马来酸系单体的含量为40‑60重量份,过氧化苯甲酰的含量为5‑12重量份,白油的含量为5‑10重量份。本发明提供的橡胶加工改性母胶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,从而能够更好地提高轮胎胎面胶的强度,降低其生热,提高抗湿滑性,降低滚动阻力,以及降低混炼过程中能耗。
