Problems solved by technology

Due to the presence of solvent in the thermal curing system, the solvent volatilizes during the baking process, the thickness of the black glue is difficult to control, and uneven filling may occur. The solvent will also cause environmental pollution. At the same time, due to the relatively high thermal curing rate Slower, which greatly increases storage costs, and in the process of mass production, manufacturing costs will be relatively high
If the absorbing layer adopts UV curing molding technology, it can avoid solvent pollution, but the black adhesive layer is easy to absorb ultraviolet light, and the structure height of the anti-peeping film is about 100 μm, which is relatively deep, which makes the central part of the black cover rubber more difficult to cure

Abstract

The invention discloses a buckling-resistant anti-peep film. The buckling-resistant anti-peep film comprises a substrate layer and a transmitting layer arranged on the surface of the substrate layer.The transmitting layer comprises a plurality of microstructures, and a cavity is formed between every two adjacent microstructures. The anti-peep film further comprises an absorbing layer filling thecavities. The shore hardness of each of the transmitting layer and the absorbing layer is smaller than or equal to 80D. The buckling-resistant anti-peep film has the advantages that the film has hightoughness, can resist buckling and does not have cracks when being buckled; the adhesion among the layers of the anti-peep film is excellent, and the layers are not easy to peel off; each of the transmitting layer and the absorbing layer is made from a solution-free UV curing system, environmental pollution is avoided, and the UV curing system of the absorbing layer solves the problem that light absorbing materials of conventional anti-peep films are difficult to cure.

Description

technical field [0001] The invention belongs to the technical field of anti-peeping film, and in particular relates to a anti-peeping film resistant to bending. Background technique [0002] With the development of the times, people pay more and more attention to personal privacy, and the anti-spy film was born. The use of anti-spy film can allow people to block the sight of people around them when they use personal computers and mobile phones in public places, and protect personal privacy. In addition, on the ATM machine, the anti-spy film can block the light on the side, so that people on both sides cannot see the screen, which protects the privacy of the ATM machine operator. At present, the application of anti-peeping film has become more and more extensive. [0003] However, the existing anti-spy film has high hardness, and it is unavoidable to bend and curl it during use. Cracks are prone to appear from time to time, affecting the appearance and clarity of the scree...
