Abstract

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.

Description

technical field [0001] The invention relates to a protective film, in particular to a protective film for an electronic screen. Background technique [0002] Conductive film is divided into three categories: ITO conductive glass, ITO conductive film and non-ITO conductive film. Among them, non-ITO conductive film is an emerging industry in flexible screens with a good market prospect. In the manufacturing process, the surface of the main substrate of the non-ITO conductive film is not resistant to scratches and is easily polluted. Therefore, a specific protective film needs to be used to prevent scratches and pollution on the surface when making the conductive film. In addition, due to the particularity of the non-ITO conductive film production process, high-temperature baking treatment is required during the production process. The high-temperature baking treatment process is an extremely strict test for the product, mainly because the current protective film is very easy t...
