The invention relates to an AG (anti-glare) film, which mainly comprises an organic solvent, PMMA (poly(methyl methacrylate)), a polyfluorosiloxane block-containing urethane-acrylate copolymer, Arabicgum, nanoscale silica sol, lithium silicate / sodium silicate / potassium silicate, a light stabilizer, an antioxidant, a flatting agent, an anti-blocking agent and a water-retaining agent. After the prepared liquid anti-glare film is sprayed on the surface of glass or tempered glass, the transparence of the glass and the tempered glass is not affected, and the aberration of light passing through theglass or the tempered glass cannot occur. After the anti-glare film is sprayed on the surface of the glass, an incandescent bulb is used for illumination for a long time, the temperature of the surface of the glass is increased after a period of time, and the AG (anti-glare) film sprayed on the surface of the glass does not fall off due to heating, and does not become yellow. After the anti-glarefilm is sprayed and the surface coated with the anti-glare film is irradiated by light, the light is diffusely scattered on the surface of the anti-glare film, so that the reflection phenomena are reduced, and therefore the phenomenon that a user cannot clearly see the screen is prevented.
