The invention relates to the field of rubber, and discloses a rubber processing modified master batch and a preparation method and application thereof, a rubber composition and application thereof, and vulcanized rubber and a preparation method and application thereof, the rubber processing modified master batch comprises a mercapto acid monomer, an ethylene-vinyl acetate copolymer and white carbon black; wherein the content of the mercapto acid series monomer is 40-55 parts by weight, the content of the ethylene-vinyl acetate copolymer is 15-35 parts by weight, and the content of the white carbon black is 15-30 parts by weight. The rubber processing modified master batch provided by the invention can improve the compatibility and dispersity of a mercapto acid monomer 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,公开了一种橡胶加工改性母粒及其制备方法与应用、橡胶组合物与应用、硫化橡胶及其制备方法与应用,其中,所述橡胶加工改性母粒包含巯基酸系单体、乙烯‑醋酸乙烯酯共聚物和白炭黑;其中,巯基酸系单体含量为40‑55重量份,乙烯‑醋酸乙烯酯共聚物含量为15‑35重量份,白炭黑含量为15‑30重量份。本发明提供的橡胶加工改性母粒能够改善巯基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的能耗。
