Matte antistatic agent for release film

Abstract

The invention discloses a mist antistatic agent for a release liner. The release liner comprises a body paper layer with the upper surface and the lower surface laminated with a PE (polyethylene) film and a PET (polyethylene glycol terephthalate) film respectively, the other surface of the PET film on the body paper layer is coated with a mist antistatic coating, the other surface of the mist antistatic coating is coated with a mold release coating, the mist antistatic coating is formed by coating the mist antistatic agent, the mist antistatic agent comprises the following components according to mass percentage: 3.8-4.2% of silica granules, 26-28% of crylic acid polyhydric alcohols with average molecular weight of 500-2000, 36-38% of resin of oxyalkylene polyhydric alcohols, 17.5-18.5% of polyethylene glycol, 5.8-6.2% of cyclic dimethyl siloxane, and 7.5-8.5% of 1-hydroxy cyclohexyl phenyl ketone-photoinitiator 184. According to the mist antistatic agent, the problem of poor binding force and release force of the laminated layer of the release paper and the mold release coating is solved, and the antistatic property and scratch resistance of the film surface are improved.

Description

technical field [0001] The invention relates to a matte antistatic agent, in particular to a matte antistatic agent for release films. Background technique [0002] Release paper, also known as release paper and release 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 layer of coating layer (the material used is mainly polyethylene) on the surface of the bottom paper layer of the release paper, and then a layer of release agent coating is applied on the surface of the coating layer. (The material used is mainly silicone oil) to obtain release paper. However, due to the high flatness of the coating layer, the adhesion between the release agent coating and the coating layer is poor. When the release paper is attached to the film coated with a high-viscosity adhesive, it will easily lead to The release agent coating is taken away by the adhesive with greater a...

Problems solved by technology

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 taken away by the adhesive with greater adhesion, thus forming a difficult-to-clean release agent coating area on the local surface of the film, destroying the overall purity and consistency of the film

Moreover, due to the excessive static electricity in the production process, the release coating layer is partially uneven, which not only affects the stability of the peeling force of the product, but also easily generates static sparks and causes fires.
