Rubber, preparation method thereof and sleeper mat

The invention discloses rubber, a preparation method of the rubber and a sleeper cushion. Comprising the following raw material components in parts by weight: 90-110 parts of butadiene styrene rubber, 3-7 parts of high styrene, 40-60 parts of white carbon black, 5-8 parts of a silane coupling agent, 30-40 parts of a filling material, 4-6 parts of an active agent zinc oxide, 1-2 parts of an active agent stearic acid, 1.8-2.5 parts of a vulcanizing agent sulfur, 1-2 parts of an accelerant dithio-dibenzothiazole, 0.8-1.5 parts of an accelerant benzothiazole sulfenamide compound and 0.5-1 part of an accelerant 4, 4 '-dithio-dimorpholine. Through mutual synergism of the rubber raw material components and the ratio thereof, the prepared rubber has excellent mechanical properties, weather resistance and chemical resistance, and meanwhile, the insulating property is remarkably improved. 本发明公开了一种橡胶及其制备方法与轨枕垫，该橡胶，按质量份数计，包括如下原料组分：丁苯橡胶90～110份、高苯乙烯3～7份、白炭黑40～60份、硅烷偶联剂5～8份、填充材料30～40份、活性剂氧化锌4～6份、活性剂硬脂酸1～2份、硫化剂硫磺1.8～2.5份、促进剂
