The invention provides a blooming barrier film, a preparation method thereof and a method for inhibiting blooming of rubber, and relates to the technical field of rubber. The blooming barrier film provided by the invention comprises a vulcanized rubber matrix and a nanofiber membrane arranged in the vulcanized rubber matrix, a first adsorbent is attached to one side of the nanofiber membrane; and the average pore size of the blooming barrier film is 50-100 nm. The blooming barrier film provided by the invention has a porous network structure, according to the filtering principle of the blooming barrier film, the nanofiber film can block migration of compounding ingredients in rubber, and according to the adsorption principle, the first adsorbent can adsorb smaller particles which cannot be filtered by the nanofiber film, so that the blooming phenomenon of the rubber is inhibited. In addition, the blooming barrier film does not influence the appearance of a rubber product or the adhesive force of rubber. 本发明提供
