The invention relates to the field of rubber, and discloses a rubber processing aid 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 aid comprises a mercapto acid monomer, solution polymerized styrene-butadiene rubber and white carbon black, relative to 100 parts by weight of solution polymerized styrene-butadiene rubber, the content of the mercapto acid monomer is 60-200 parts by weight, and the content of the white carbon black is 20-66.7 parts by weight. The rubber processing aid comprises a mercapto acid monomer, solution polymerized styrene-butadiene rubber and white carbon black, the mercapto acid monomer, the solution polymerized styrene-butadiene rubber and the white carbon black are mixed in advance to prepare the rubber processing aid, and the compatibility and dispersity of the mercapto acid monomer and a rubber matrix can be remarkably improved; further, the strength, the wear resistance and the wet skid resistance of the vulcanized rubber can be remarkably improved on the premise of ensuring that the vulcanized rubber has low heat generation.

    本发明涉及橡胶领域,公开了一种橡胶加工助剂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。该橡胶加工助剂包含巯基酸系单体、溶聚丁苯橡胶和白炭黑;相对于100重量份的溶聚丁苯橡胶,所述巯基酸系单体的含量为60‑200重量份,所述白炭黑的含量为20‑66.7重量份。该橡胶加工助剂包含巯基酸系单体、溶聚丁苯橡胶和白炭黑,预先将巯基酸系单体与溶聚丁苯橡胶以及白炭黑混合制备得到橡胶加工助剂,能够显著改善巯基酸系单体与橡胶基体的相容性以及分散性,进而能够在保证硫化橡胶具有低的生热的前提下,使得硫化橡胶的强度、耐磨性、抗湿滑性显著提高。
