NOVELTY - The utility model claims a heat sublimation transfer paper for slowing reverse osmosis, comprising a paper base material, a water-absorbing resin layer, graphene; a silicon dioxide film and a dye adsorption layer; the surface of the paper substrate is covered with a water-absorbing resin layer; the surface of the water-absorbing resin layer is attached with graphene; the graphene is covered with a silicon dioxide film; the surface of the silicon dioxide film is pressed with a dye adsorption layer. Through said method, the utility model claims a heat sublimation transfer paper for slowing reverse osmosis; the surface of the raw paper is attached with a dense film; the film porosity is low; the dye molecule is difficult to pass through the dense film when transfer printing; the dye molecule is sublimated from the positive direction in the single direction; at the same time, the graphene is used for realizing water permeation and absorption; so as to accelerate the production purpose of the drying speed.
