Problems solved by technology

[0003] The object of the present invention is to provide a kind of anti-scratch anti-static anti-scratch anti-scratch release paper, the anti-scratch anti-scratch anti-static anti-scratch release paper not only solves the problem of low bonding force between the lamination layer of the release paper and the release agent coating, and the problem of peeling off. The force is unstable, and the antistatic performance of the film surface is improved, and at the same time, the scratch resistance performance is also improved.

Abstract

The invention discloses an anti-scuffing matt-surface antistatic release paper. The anti-scuffing matt-surface antistatic release paper comprises a release raw paper and a film layer. The other surface of the film layer is coated with a matt-surface antistatic layer having thickness of 0.2 to 2 micrometers. The other surface of the matt-surface antistatic layer is coated with a silicone oil layer. The surface of the matt-surface antistatic layer contacting with the silicone oil layer is provided with multiple concave and convex points. The matt-surface antistatic layer comprises 2 to 6% of silica particles, 20 to 30% of acrylic polyol having average molecular weight of 500 to 2000, 35 to 45% of polyoxyalkylene polyol having average molecular weight of 200 to 2500, 15 to 20% of polyethylene glycol, 4 to 8% of cyclomethyl siloxane, and 5 to 10% of 1-hydroxycyclohexylphenyl ketone-photoinitiator 184. The anti-scuffing matt-surface antistatic release paper solves the problem that the existing release paper has poor adhesion between a lamination layer and a release agent coating and unstable peel strength, improves antistatic performances of the film surface, and improves scuffing resistance.

Description

technical field [0001] The invention relates to a matte surface antistatic release paper, in particular to an anti-scratch matte antistatic release paper. Background technique [0002] Release paper, also known as release paper and anti-adhesive paper, is mainly used to stick the adhesive layer on the surface of the tape to protect the surface of the tape. The existing release paper is generally coated with a film layer (the material used is mainly polyethylene) on the surface of the bottom paper layer of the release paper, and then coated with a layer of release agent coating on the surface of the film layer (The material used is mainly silicone oil) to obtain a release paper. However, due to the high flatness of the coating layer and the poor adhesion between the release agent coating and the coating layer, when the release paper is attached to the film coated with a high-viscosity adhesive, it is easy to cause cracks on the release paper. The release agent coating is ta...
