The invention belongs to the technical field of bicycle tire production, and discloses a high-wear-resistance bicycle tire rubber composition which comprises the following components: 20-30 parts of emulsion polymerized styrene-butadiene rubber, 20-30 parts of butadiene rubber, 10-20 parts of high-wear-resistance carbon black, 5-10 parts of modified white carbon black, 2-3 parts of an anti-aging agent, 1-2 parts of an accelerant, 0.5-1.5 parts of a vulcanizing agent and 2-4 parts of an active agent. According to the scheme, the emulsion polymerized styrene-butadiene rubber has the advantages of wear resistance, heat resistance, aging resistance and the like, the emulsion polymerized styrene-butadiene rubber has good comprehensive performance and a mature process, and the butadiene rubber is particularly excellent in cold resistance, wear resistance and elasticity after being vulcanized and generates little heat under dynamic load, so that the emulsion polymerized styrene-butadiene rubber and the butadiene rubber in equal proportion are used as raw materials; and the rubber composition prepared by matching other auxiliary raw materials has high wear resistance, so that the bicycle tire prepared from the rubber composition in the scheme also has high wear resistance.
本发明属于自行车轮胎生产技术领域,公开了一种高耐磨自行车轮胎橡胶组合物,包括以下组分:乳聚丁苯橡胶20‑30份、顺丁橡胶20‑30份、高耐磨炭黑10‑20份、改性白炭黑5‑10份、防老剂2‑3份、促进剂1‑2份、硫化剂0.5‑1.5份、活性剂2‑4份。本方案中乳聚丁苯橡胶具备耐磨、耐热、耐老化等优点,且乳聚丁苯橡胶具有良好的综合性能,工艺成熟,顺丁橡胶硫化后其耐寒性、耐磨性和弹性特别优异,动负荷下发热少,因此通过等比例的乳聚丁苯橡胶和顺丁橡胶为原料,并搭配其他辅助原料制得的橡胶组合物具备高耐磨性,因此通过本方案的橡胶组合物制得的自行车轮胎也具备高耐磨性。
