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.
