Abstract

The invention discloses a PU adhesive etching protective film, relates to the technical field of protective film structures, and aims to solve the problems that a conventional PU adhesive etching protective film is poor in anti-static effect and is prone to falling off after being used for a period of time. The PU protective film comprises a PET anti-etching film, a PU adhesive, anti-static particles, a release film, a waterproof breathable film and a wear-resistant layer; first adhesion convex blocks are arranged at one end of the PET anti-etching film; the PU adhesive is arranged below the first adhesion convex blocks; the anti-static particles are arranged in the PU adhesive; the release film is arranged below the PU adhesive; a first adhesion layer is arranged on the PET anti-etching film; the waterproof breathable film is arranged on the first adhesion layer, first air holes are formed in the waterproof breathable film, a second adhesion layer is arranged above the waterproof breathable film, and a wear-resisting layer is arranged above the second adhesion layer; wear-resisting bumps are arranged at one end of the wear-resisting layer, and second air holes are formed in the wear-resisting layer.

Description

technical field [0001] The invention relates to the technical field of protective film structure, in particular to PU glue etching protective film. Background technique [0002] PU glue etching protective film is a functional protective film made of transparent PET film as the base material, coated with PU glue on one side, and bonded with release film on the back. PU glue etching protective film has good anti-etching properties, PU The plastic etching protective film has a high degree of cleanliness and strict foreign matter control; it has excellent adhesive performance for the object to be pasted; there is no residual glue after being pasted, and the product transparency is over 90%. The PU plastic etching protective film will gradually become a protective film in the future main force in the market. [0003] However, the existing PU glue etching protective film has poor anti-static effect, and it is easy to absorb dust due to static electricity when in use, thereby caus...
