Problems solved by technology

Most of the existing antistatic protective films are a layer of ordinary PET base film, coated with antistatic coating and then coated with polyurethane glue, the antistatic film is fogged, uneven coating, local antistatic instability, antistatic effect It is poor, and does not have the functions of printing and scratch resistance. The 100-grid hardness of the non-scratch PU protective film surface is ≤ HB. In addition, the surface dyne value of the product is due to the silicon release film and the back of the substrate itself is not electrical. Faint surface, surface dyne value <40

Abstract

The invention discloses a printable anti-scratch anti-static protective film which sequentially comprises a printable anti-scratch coating, an optical PET base material layer, a modified anti-static layer and a non-silicon release film layer from top to bottom, wherein the printable anti-scratch coating is made of polyurethane, and the modified anti-static layer is an anti-static polyurethane adhesive layer. The invention also discloses a preparation method of the printable anti-scratch anti-static protective film, which comprises the following steps of: coating one surface of an optical PET base material layer with printable anti-scratch coating liquid on line, coating the other surface of the optical PET base material layer with anti-static polyurethane glue after the coating is cured and dried, baking the product in a baking oven, taking the product out of the baking oven, attaching a non-silicon release film on line, and rolling and pulling the product into an oven for curing to obtain the printable anti-scratch anti-static protective film. The anti-scratch anti-static film has a very good anti-scratch effect, and the phenomenon of local anti-static instability caused by fogging and uneven coating of the anti-static film is avoided.

Description

technical field [0001] The invention relates to a printable anti-scratch antistatic protective film and a preparation method thereof, belonging to the technical field of materials. Background technique [0002] Mobile phone products and other electronic products are used more and more widely, and protective films have become an indispensable part in the processing and post-shipment of mobile phone glass and touch panels. Most of the existing antistatic protective films are a layer of ordinary PET base film, coated with antistatic coating and then coated with polyurethane glue, the antistatic film is fogged, uneven coating, local antistatic instability, antistatic effect It is poor, and does not have the functions of printing and scratch resistance. The 100-grid hardness of the non-scratch PU protective film surface is ≤ HB. In addition, the surface dyne value of the product is due to the silicon release film and the back of the substrate itself is not electrical. Faint face...
