Embodiment 1~5

[0028] Embodiment 1~5: a kind of preparation method of novel matte surface antistatic release paper mainly consists of the following steps:

[0029] Step 1. Use a laminating machine to coat a film layer 2 on one surface of a release paper base paper 1. After the film layer 2 is cooled, apply an adhesive layer on the other surface of the release paper base paper 1 3 to obtain the substrate layer;

[0030] Step 2, coating a layer of matte antistatic coating 5 with a thickness of 0.2 to 2 microns on one surface of a film layer 4, the matte antistatic coating 5 is composed of the following components in mass percentage:

[0031] Silica particles 2~6%,

[0032] Acrylic polyols with an average molecular weight of 500~2000 20~30%,

[0033] Polyoxyalkylene series polyol resin with an average molecular weight of 200~2500 35~45%,

[0034] Polyethylene glycol 15~20%,

[0035] 1-Hydroxycyclohexyl phenyl ketone-photoinitiator 184 5~10%;

[0036] The particle size of the silica particl...

Abstract

The invention discloses a preparation method of novel matte anti-static release paper. One surface of release paper body paper is coated with a coating layer through a coating machine, and one surface of a thin film layer is coated with a matte anti-static coating with a thickness of 0.2-2 micrometres. Under the influence of the used ultraviolet rays which are of a wave band of 280-350nm and of an illumination of 1200mW / cm<2>, components, contained in the matte anti-static coating, including 2-6% of silica particles, 20-30% of acrylic polyol with the average molecular weight of 500-2000, 35-45% of resin of polyoxyalkylene polyols with the average molecular weight of 200-2500, 15-20% of polyethylene glycol and 5-10% of 1-1-hydroxy-cyclohexyl phenyl ketone-photoinitiator 184 react to obtain the matte anti-static coating. The thickness of the matte anti-static coating is 4-10 micrometres. The preparation method of the novel matte anti-static release paper not only solves the problems that the binding force between the coating layer and the release agent coating of the release paper is not strong and the release force between the coating layer and the release agent coating of the release paper is not stable, but also promotes the anti-static performance of the surface of the film, and meanwhile promotes the anti-scraping performance.

Description

technical field [0001] The invention relates to a preparation method of a novel matte antistatic release paper, in particular to a preparation method of a novel matte antistatic release paper with high adhesion and stable peeling force. 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,...
