Embodiment 1

[0029] Embodiment 1, a kind of preparation method of novel matte release paper

[0030] See attached figure 1 Shown, a kind of preparation method of novel matte release paper, the preparation steps are as follows:

[0031] First of all, the surface of the base paper of the release paper is treated to make the surface free of paper dust and stains.

[0032] (1) On the surface of one side of the release paper base paper, use a laminating machine to coat a layer of PE coating layer 1. After the coating layer 1 cools down, coat the surface of the other side of the release paper base paper Cloth one layer of adhesive layer 3 to obtain the substrate layer, and set aside. The laminating machine can use the high-speed extrusion single-sided casting composite unit type A produced by Changzhou Laiyi Plastic Machinery Co., Ltd.

[0033] (2) Coating a layer of matte coating agent with a thickness of 0.2 to 2 microns on the surface of the polyethylene terephthalate film layer. The formu...

Abstract

The invention relates to a preparation method of novel cloudy-surface release paper, which comprises the following steps that: a film-coated layer is coated on one side surface of a base release paper, a cementing compound layer is coated on the other side surface of the base release paper after being cooled to obtain a substrate layer to standby use; a layer of cloudy-surface coating agent with the thickness of 0.2 micrometer to 2 micrometers is coated on the surface of a film layer; the cloudy-surface coating agent is radiated by ultraviolet rays to obtain a cloudy-surface coating, and then a layer of mold release agent is coated on the surface of the cloudy-surface coating to obtain a cloudy-surface release layer for standby use; and the cloudy-surface release layer is bonded with the substrate layer. Sine the polyester cloudy-surface coating is firstly coated on the surface of the film layer, a plurality of convex-concave structures are obtained on the surface of the film layer after being processed; and then the silicon release agent coating is coated on the surface of the cloudy-surface coating, the bottom surface of the silicon release agent coating at a liquid state penetrates into concaves on the surface of the polyester cloudy-surface coating and the silicon release agent coating is fixedly connected with the polyester cloudy-surface coating through the concaves after being solidified, so the bonding force is firmer and more reliable.

Description

technical field [0001] The invention relates to a preparation method of a novel matte release paper, in particular to a preparation method of a novel matte release paper with high adhesion and adjustable 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 on the surface of the film layer ( The material used is mainly silicone oil) to obtain 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...
