Embodiment 1

[0028] (1) Use a corona treatment machine to treat the surface of the backing paper of the release paper with a power of 600W for 100s.

[0029] (2) Mix polyethylene and isocyanate-modified polyethylene uniformly in a mass ratio of 1:0.1, first heat the bridge at a temperature of 180°C, then increase the temperature to 280°C, and apply a pressure of 10Mpa after melting It is extruded and kept at a temperature of about 320°C when laminating. After coating, the coated paper is obtained, and the coating amount is 10g / m 2 .

[0030] (3) The conveyor belt sends the coated paper to the roller with a convex module at a conveying speed of 60m / min for rolling.

[0031] After rolling, grooves appear on the surface of the coated paper. The size of the groove is 15mm×15mm, the depth of the groove is 1.8mm, and the width of the well-shaped side on the side is 12mm. Cool the fluted coated paper.

Abstract

The invention belongs to the field of light industry papermaking, and relates to a method for preparing anti-adhesive paper with a well-shaped groove structure. In this method, polyethylene and modified polyolefin are evenly mixed in a mass ratio of 1:0.1 to 0.2, heated and melted, and coated onto the corona pretreated backing paper with a coating amount of 10- 20g / m2, after cooling, the coated paper is obtained; after the coated paper is rolled by a roller with a convex module, grooves appear on the surface; the silicone oil is coated with 1.0-2.0g / m2 of dry silicon by a coating machine The amount of coating is evenly coated on the surface of the coated paper; then it is dried at 100°C to 200°C in three temperature sections, and the release paper is obtained after cooling. With the method of the present invention, after the anti-adhesive paper is rolled into grooves, the concave part of the anti-adhesive paper is not coated with anti-adhesive agent, thereby reducing the amount of silicone oil used, the amount of organic solvent used, the production cost, and environmental protection. Energy saving requirements.

Description

technical field [0001] The invention belongs to the field of light industry papermaking, and relates to a method for preparing release paper, in particular to a method for preparing release paper with a well-shaped groove structure. Background technique [0002] The release paper is mainly pasted on the glued surface of the tape to protect the adhesive layer on the surface of the tape. The anti-adhesive paper is composed of a base paper, an isolation layer and an anti-adhesive layer. The preparation process is to coat a layer of release agent on the entire surface of the base paper (the release agent used mainly includes polyethylene), and then coat the surface of the coating layer with a layer of release agent. A layer of release agent (adopted release agent is mainly silicone oil) is coated to obtain release paper. [0003] Silicone oil is generally a colorless or light yellow, odorless, non-toxic, non-volatile liquid. Silicone oil is insoluble in water, methanol, glycol...
