The invention relates to the technical field of rubber, and discloses rubber processing modified master batch, vulcanized rubber, a preparation method of the rubber processing modified master batch and the vulcanized rubber and application of the vulcanized rubber in tire treads, the rubber processing modified master batch is composed of 76-81 parts by weight of a modifier, 14-17 parts by weight of a matrix material and 1-3 parts by weight of white oil, the content of the white oil is 3-7 parts by weight; the base material comprises a polyolefin elastomer, ethylene propylene diene monomer and an ethylene-vinyl acetate copolymer. 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, and the wet skid resistance is improved.

    本发明涉及橡胶技术领域,公开了一种橡胶加工改性母胶与硫化橡胶及其制备方法以及在轮胎胎面中的应用,其中,所述橡胶加工改性母胶由改性剂、基体材料和白油组成,且所述改性剂的含量为76‑81重量份,所述基体材料的含量为14‑17重量份,所述白油的含量为3‑7重量份;所述基体材料包含聚烯烃弹性体、三元乙丙橡胶和乙烯‑醋酸乙烯酯共聚物。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,以及提高抗湿滑性。
