A kind of release film for directly coating concave-convex pattern release agent and its coating device

Abstract

The invention discloses a release film directly coated with a concave-convex pattern release agent, comprising a release film, the release film comprising a base material layer and a first release layer, the base material layer and the first release film An antistatic layer is arranged between the layers, the upper surface of the first release layer is coated with a second release layer, and the second release layer is a twill-type concave-convex pattern, a diamond-shaped grid-like concave-convex pattern or a honeycomb pattern Release agent layer with concave and convex texture. In the present invention, the distance between the scraper and the surface of the coating roller is adjusted to adjust the amount of the release agent scraped off, so that the thickness of the release agent adhered to the surface of the coating roller is different, and the production and processing of different release films are rolled. The thickness and dosage of the release agent will also be adjusted accordingly, the scraper is manually adjusted, which is convenient for positioning, and the device is easy to operate, which increases the production adaptability of the production device and different release films. Coating rollers with different anilox patterns can be adjusted according to the needs of production for production and processing, which saves the cost of production equipment.

Description

technical field [0001] The invention relates to the technical field of release film production, in particular to a release film directly coated with a release agent for concave-convex lines and a coating device thereof. Background technique [0002] Release film refers to a film that can be distinguished on the surface of the film. The release film is not sticky or slightly sticky after contact with a specific material under limited conditions. According to the different required release force of the release film, the product glue is isolated. The viscosity is different, and the release force is adjusted accordingly, so that it can achieve a very light and stable release force during peeling. [0003] The release force of the existing release film is to adjust the dosage of the release agent in the production process to adjust the release force of the release film. When scraping the release agent on the surface of the coating roller, It can only be scraped at a fixed angle ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a release film and a coating device for directly coating a concave-convex texture release agent, so as to solve the problem that the coating roller in the prior art can only roll out a concave-convex texture. When the release area is adjusted by the texture, it is necessary to disassemble and replace the coating roller to adjust, and it is impossible to install a variety of coating rollers with different concave-convex textures in one device to adjust the problem, so that the present invention can be completed with a set of equipment. The effect of the production of a release film with a concave-convex texture
