The invention relates to an airtight rubber material, a rubber material preparation method and a tire. Based on 100 parts by weight of airtight layer rubber in calculation, a tread reinforcing systemcomprises 40-70 parts of general carbon black, 0-20 parts of a flat silicate reinforcing material and 0-1.0 part of graphene; the graphene is prepared by adopting an oxidation-reduction method, has asingle-layer proportion of larger than 90%, is uniformly mixed into an aqueous solution according to a proportion of 0.4 permill, and is pre-dispersed into the general carbon black during production application, wherein the pre-dispersion mixing proportion is 0.5-1.0; the flat silicate reinforcing material is formed by double surface modification of natural clay minerals; the pH value of the flatsilicate reinforcing material is 9.2 when the concentration of the flat silicate reinforcing material is 10%; and the content of 325-mesh fine powder of the flat silicate reinforcing material is 0.03%. According to the invention, the graphene is prepared through the oxidation-reduction method, has the graphene single layer proportion of larger than 90%, and is uniformly mixed into the aqueous solution according to the proportion of 0.4 permill. Thus, the airtight three-dimensional steric hindrance of the airtight layer is significantly improved; the elasticity and flexibility of the rubber material are improved; and the airtight performance of the rubber material is improved.
