Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-2, the present utility model provides the following technical solutions: the TP protection film comprises a PET base film layer 1, wherein an antistatic acrylic adhesive layer 2 and a hardening layer 3 are respectively adhered to the upper surface and the lower surface of the PET base film layer 1 through adhesives, and the adhesives are modified photo-thermal dual-curing acrylic polyurethane glue; the upper surface of antistatic acrylic adhesive layer 2 is coated with antistatic coating 4, transparent protective film layer 5 is attached to the upper surface of antistatic coating 4, silica gel pressure sensitive adhesive layer 6 is attached to the lower surface of hardening layer 3, and release film layer 7 is adhered to the lower surface of silica gel pressure sensitive adhesive layer 6.

In the embodiment, the UV absorber and the UV stabilizer are added into the adhesive (the modified photo-thermal dual-curing acrylic polyurethane layer), so that the mobile phone protective film can be prevented from being influenced by environmental ultraviolet rays on the performance of the mobile phone protective film in the manufacturing and storage and transportation processes; the antistatic coating 4 is a polylactam resin coating doped with diethyl ether, and is arranged in such a way that the antistatic protection film is antistatic during the production and preparation process and during the use process.
