A release film with light release force after UV light irradiation and its coating device

Abstract

The invention discloses a release film whose release force becomes lighter after UV irradiation and a coating device thereof, comprising a release film, the release film comprising a base material layer and a first release layer, the base material An antistatic layer is arranged between the layer and the first release layer, the upper surface of the first release layer is coated with a DMPA layer, and the upper surface of the DMPA layer is coated with a second release layer with adjustable area , the antistatic layer is a polymer conductive layer in polythiophene, and the substrate layer is a PET layer. In the present invention, the compression springs are squeezed sequentially, and the elastic force of the compression springs will push the fixed plate to move, so that the front and rear fixed plates slide towards the middle, drive all the decks to move evenly to the center position, and drive all the coating roller installation mechanisms to the center The position of the dot moves evenly, adjust the number of coating rollers in contact with the release film, and then adjust the dose of the release agent to adjust the release force of the produced release film, increasing the production device and different release Membrane suitability for production.

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
