Abstract

The invention discloses an acrylic protective film for an aluminum-plastic film manufacturing process. The acrylic protective film comprises an antistatic layer, a base material layer and an adhesivelayer; two sides of the base material layer are coated with the antistatic layer and the adhesive layer respectively, and the adhesive layer is obtained by coating the base material layer with an acid-free acrylic adhesive and drying the base material layer. The acid-free acrylic adhesive comprises the following components in parts by weight: acid-free acrylic resin, toluene diisocynate, an auxiliary agent, a surfactant and ethyl acetate, wherein an acid-free acrylic glue is glue with the solid content of 20%. The antistatic treatment is carried out on the PET surface of the base material layer, so that the problem of lamination adsorption is effectively solved; meanwhile, the acid-free acrylic glue is prepared, the reaction with a CPP layer on the surface of the aluminum-plastic film is avoided, the viscosity is stable, and no residual glue is left after stripping; and in addition, when the acid-free acrylic glue is prepared, proper acrylic resin is selected; and toluene diisocynate is matched, so that the crosslinking degree of the glue can be reduced, and the glue has the characteristic of high wettability.

Description

technical field [0001] The invention belongs to the technical field of acrylic protective films, and in particular relates to an acrylic protective film used in the aluminum-plastic film manufacturing process and a preparation method thereof. Background technique [0002] Aluminum plastic film is widely used in soft battery packs, involving EV, mobile phone batteries and other fields. The aluminum-plastic film process will use the acrylic protective film that carries the process. The process conditions are to bake at about 80°C for 20 hours, and then heat press at 4Mpa 90°C for 4 hours to quickly tear the protective film. The aluminum-plastic film is easy to peel off and has no glue residue. . Most of the protective films at this stage are single-layer acrylic protective films with OPP structure, which have the following defects: the surface of OPP material is relatively smooth, has a certain polarity, and is easy to be stacked and adsorbed; the surface of the aluminum-plas...
