Release film with release force lightened after UV illumination and coating device thereof

Abstract

The invention discloses a release film with release force lightened after UV illumination and a coating device thereof. The release film comprises a release film body, wherein the release film body comprises a base material layer and a first release layer, an antistatic layer is arranged between the base material layer and the first release layer, the upper surface of the first release layer is coated with a DMPA layer, the upper surface of the DMPA layer is coated with a second release layer with an adjustable area, the antistatic layer is a polythiophene macromolecule conductive layer, and the base material layer is a PET layer. According to the release film, compression springs are sequentially extruded, and the elastic force of the compression springs can push fixing plates to move, sothat the front and rear fixing plates slide towards the middle, all clamping seats are driven to uniformly move towards the center point position, all coating roller mounting mechanisms are driven touniformly move towards the center point position, the number of coating rollers in contact with the release film is adjusted, then the dosage of an adhesive release agent can be adjusted, the releaseforce of the produced release film is adjusted, and the production adaptability of a production device to different release films is improved.

Description

technical field [0001] The invention relates to the technical field of release film production, in particular to a release film with light release force after UV irradiation and a coating device thereof. Background technique [0002] The 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 contacting with a specific material under limited conditions. According to the release force of the release film required, the product glue is isolated. The viscosity is different, and the release force is adjusted accordingly, so that it can achieve an extremely light and stable release force when peeling. [0003] The release force of the existing release film is to adjust the release force of the release film during the production process by adjusting the amount of the release agent, and the existing production equipment can only be used for one type of release film. It is impossible to adjust the am...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a release film with light release force after UV irradiation and a coating device thereof, so as to solve the problem that the coating area of ​​the release agent in the coating equipment in the prior art cannot be adjusted according to production requirements, Thereby it is inconvenient to change the release force problem of the release film, so that the present invention can complete the production effect of the release film with multiple different release forces only through a set of equipment
