The invention relates to the technical field of tire preparation, in particular to a tire inner liner rubber composition containing bio-based modified cracked carbon black, a mixing method and a tire. According to the tire inner liner rubber composition containing the bio-based modified cracked carbon black, the bio-based modified cracked carbon black is added into the tire inner liner rubber composition, the number of phenolic hydroxyl groups, carbonyl groups, methoxyl groups and carboxyl groups is increased after the cracked carbon black is modified, and the surface activity of the cracked carbon black is improved; the carbon black can replace semi-reinforced carbon black or inorganic filler after being added into a rubber composition, the prepared rubber composition is low in heat generation, the rolling resistance of tires is reduced, and carbon emission is reduced.
本发明涉及轮胎制备技术领域,尤其涉及一种含生物基改性裂解碳黑的轮胎气密层橡胶组合物、混炼方法和轮胎。一种含生物基改性裂解碳黑的轮胎气密层橡胶组合物,该轮胎气密层橡胶组合物加入生物基改性裂解碳黑,该裂解炭黑经改性后具有酚羟基、羰基、甲氧基和羧基数量增加,提高了裂解炭黑的表面活性,加入到橡胶组合物中,加入到橡胶组合物中,可代替半补强炭黑或无机填料,制备的橡胶组合物生热低,降低了轮胎滚阻,降低了碳排放。
