Problems solved by technology

With the development of mobile terminal equipment, people are gradually processing more and more work on smart devices such as mobile phones and tablets. At present, there are more and more applications of curved screens in the market, but for curved screens, the current technology It is difficult to make qualified curved glass, and the lamination of curved glass and AB glue is also difficult to solve. In addition, it is difficult to manufacture large-screen tempered glass film
Moreover, as manufacturers have specially treated the surface of their own screens to reduce its surface energy and make it have an anti-fouling effect, this also makes it difficult for ordinary protective films to fit the screen tightly, and the curved edges are easy to lift and cannot fit perfectly
[0003] Some manufacturers try to use relatively soft TPU to produce curved full-cover film, but TPU is expensive and the manufacturing cost is too high, resulting in a higher price, which is difficult for consumers to accept

Abstract

The invention discloses a hot-press molded protective film with shinning and antistatic effects and a preparation method thereof. The protective film can be used for comprehensively protecting a curved screen, and has an attractive appearance since shinning and antistatic effects are extra added. The protective film comprises a film protecting layer, an application layer and a release layer from top to bottom, wherein the application layer comprises a UV hardened layer, a base material A and an adhesive layer A; the principle component of the UV hardened layer is an acrylic resin layer, the base material A is a PET film, and the principle component of the adhesive layer is an organic silicone pressure-sensitive adhesive layer; and the thickness of the UV hardened layer is 2-10 mu m, the thickness of the base material A is 20-200 mu m, and the thickness of the adhesive layer A is 20-100 mu m. The hot-press molded protective film has shining and antistatic effects since shining particles and an antistatic agent are added into the application layer, and has high flexibility and cannot rebound after hot press since high-elasticity high-viscosity organic silicone pressure-sensitive adhesive is utilized in the adhesive layer.
