Preparation process of peep-proof film with high weather resistance and blue light resistance

The invention discloses a preparation process of a peep-proof film with high weather resistance and blue light resistance, and belongs to the technical field of optical thin film materials. The method comprises the following steps: S1, blending transfer printing glue; S2, conducting UV curing forming through a structural roller; and S3, conducting filling with black glue and conducting curing. According to the peep-proof film disclosed by the invention, by blending the formula, the blue light resistance and high weather resistance of the peep-proof film are improved, and unitary application is converted into multivariate application; and meanwhile, a connecting layer with a certain thickness is additionally arranged between a structural layer and a base material, so that the clarity of the peep-proof film is improved, the foldover phenomenon caused by the difference of the refractive index of resin is eliminated, the production process of the peep-proof film is thoroughly innovated, and meanwhile, the technic
