The invention discloses a preparation method of an outdoor advertising body sticker, which comprises a substrate layer, a back adhesive layer and a release layer. One side of the substrate layer is coated with the back adhesive layer, and the back adhesive layer is opposite to One side of the base material layer is provided with a release layer, and the glue solution is prepared by the following steps: 20-35 parts of methyl methacrylate, 10-30 parts of styrene, 10-20 parts of butyl acrylate, 0.5-20 parts of sodium carbonate 1.5 parts, 1-5 parts of hexachlorocyclotriphosphazene and 50-80 parts of deionized water are mixed evenly, the temperature is raised to 75-90 ℃, and 4,4'-azobis(4-cyanide is added dropwise to the mixed system) 0.5~1.5 parts of valeric acid) and 1~5 parts of acrylic acid, react for 3~5h; S2, cool to room temperature, add 1~5 parts of aluminum isopropoxide, 1~3 parts of curing agent, tripolyglycerol monostearic acid 0.2-1 part of ester and 0.1-1 part of hydroquinone are mixed evenly to obtain a glue solution; S3, the glue solution is evenly coated on the base material layer, and dried to obtain a back glue layer. The invention is easy to peel off and has no residual glue, and meanwhile, the peeling force changes little after the outdoor advertising body is pasted for a long time. |
