▎ 摘  要

NOVELTY - Anti-static transfer display screen protective film comprises a guiding layer, a charge-locking layer, an anti-transfer layer and a protective layer. The lower surface of the protective layer is provided with an anti-transfer layer. A charge-locking layer is arranged between the transfer layer and the guide layer. The anti-transfer layer is composed of 75-95 wt.% polyethylene terephthalate resin, 5-25 wt.% antistatic masterbatch. The charge-locked layer is composed of 15-35 wt.% graphene powder, 58-72 wt.% epoxy resin, 6-18 wt.% high carbon fiber and 5-25 wt.% porous aluminosilicate powder, 90-95 wt.% high carbon fiber. The guiding layer is composed of 74-86 wt.% epoxy resin, 2-14 wt.% spherical metal particles, and 10-24 wt.% low carbon fiber. The thickness of the guiding layer is equal to the diameter of the spherical metal particles, the thickness is 0.05-0.1 mm, and the low-carbon fiber is an inorganic polymer fiber with a carbon content of 60-65%. USE - Used as an anti-static transfer display screen protective film. ADVANTAGE - The film: realizes the purpose of electrostatic charge drainage, and improves the charge to charge the charge locking layer flow speed. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for production of anti-static transfer display screen protective film comprising (1) selecting a transparent polyethylene terephthalate resin film as the protective layer, (2) weighing polyethylene terephthalate resin particles and antistatic master batch, heating and melting them, mixing them, and spin-coating on the protective layer to form an uncured anti-transfer layer, (3) weighing a certain mass ratio of graphene powder, epoxy resin, high carbon fiber and porous aluminosilicate powder, mixing them and spraying them on the anti-transfer layer, (4) curing anti-transfer layer, when the charge-locking layer is not cured, weighing a certain mass ratio of epoxy resin, spherical metal particles and low-carbon fiber, and applying directly to the charge-locking layer after mixing, rotating at a low speed of 100-500 rotations/minute to pave the mixture, and forming a display screen protective film after the whole is solidified.
