The invention provides a rubber composition for a tire inner liner and a preparation method of the rubber composition, and belongs to the field of rubber for tire inner liners. The preparation method of the rubber composition for the tire inner liner comprises the following steps: primary mixing, secondary mixing and vulcanization. According to the rubber composition for the tire inner liner and the preparation method of the rubber composition, the vulcanization stability of the rubber composition for the tire inner liner in the preparation process can be improved while the processability and the oxidation resistance of the rubber composition for the tire inner liner are improved, and the situation that the air tightness of the rubber composition for the tire inner liner is not uniform is avoided; hardening and cracking are easy to occur in high and low temperature environments; the rubber composition for the tire airtight layer can keep good airtight performance and mechanical performance for a long time in high and low temperature environments, and has good bonding performance with other structural layers of a tire.

    本发明提供一种轮胎气密层用橡胶组合物及其制备方法,属于轮胎气密层用橡胶领域。所述轮胎气密层用橡胶组合物的制备方法,由以下步骤组成:一次混炼、二次混炼、硫化。本发明的轮胎气密层用橡胶组合物及其制备方法,能够在提高轮胎气密层用橡胶组合物加工性能、耐氧化性能的同时,提高轮胎气密层用橡胶组合物在制备过程中的硫化稳定性,避免轮胎气密层用橡胶组合物的气密性能不均,及在高低温环境中易于出现硬化、龟裂的问题;轮胎气密层用橡胶组合物能够在高低温环境中长期保持良好的气密性能和机械性能,且与轮胎其他结构层的结合性能好。
