The invention discloses a protective film for an electronic screen. The protective film comprises a base material layer, an
adhesive layer and a bottom layer; the
adhesive layer is prepared from, by weight, 15-20 parts of
acrylates copolymer, 10-15 parts of a cross-linking agent, 25-35 parts of
ethyl acetate, 12-16 parts of methylbenzene, 6-10 parts of
rosin resin, 5-10 parts of glycerin, 4-8 parts of a curing agent, 3-5 parts of
sodium silicate and 10-18 parts of a high temperature resistant filler. Accordingly, the formula is reasonable, and the protective film has good
viscosity,
adhesion force, retention force and initial adhesion of a rolling ball, the product is better used under the occasions at the laminating temperature being 10 DEG C or above, after laminating, an
adhesive layercan keep the performance unchanged for a long time under the environment of -20-120 DEG C, deformation such as warping cannot occur, short-term
temperature resistance can reach 180 DEG C, and the protective film is widely applied in various baking processes.
