Problems solved by technology

Chinese Invention Patent Publication CN 104057669A (publication date: 2014.9.24) discloses a production process of a fluorine release film. The release film prepared by this process has stable release force and good aging resistance, and is very suitable for use in All silicone protective tapes can be used in high temperature and high humidity environment to obtain good isolation effect, but the die-cutting effect of the release film is not good, resulting in debris and burrs, which affects the release film to a certain extent. Normal use

Abstract

The invention discloses a fluorine-containing paint and a preparation method thereof, and a fluorine release film based on coating by the fluorine-containing paint. The fluorine-containing paint usesa basic paint as a main body, and then fluorine-containing epoxy resin and diethanol amine are added; a reaction is carried out under the conditions of a pH value of 8 to 9 and a temperature of 40 to50 DEG C for 5 to 6 h so as to obtain the fluorine-containing paint; and reaction process is simple, reaction conditions are mild, and the reaction can be easily implemented. The fluorine release filmuses the fluorine-containing paint as a release layer; an adhesive layer, a first middle layer and a second middle layer are arranged between a base layer and the release layer; and the outer side ofthe base layer is provided with a thermal insulation layer. Through interaction among the above six structures, the fluorine release film has stable release force and resistance to high temperature and ageing, and does not produce chips and burrs during die cutting.

Description

technical field [0001] The invention relates to the technical field of thin films, in particular to a fluorine-containing coating, a preparation method thereof and a fluorine release film coated based on the fluorine-containing coating. Background technique [0002] The release film refers to a film with a separable surface. The release film is not sticky or slightly sticky after being in contact with a specific material under limited conditions. [0003] Release film, also known as peeling film, isolation film, separation film, barrier film, release film, film, plastic film, hole masking film, silicone oil film, silicone oil paper, anti-adhesive film, slip film, Tianna paper, release film Paper. Usually, in order to increase the release force of the plastic film, the plastic film will be treated with plasma, or coated with fluorine, or coated with a silicon release agent on the surface of the film material, so that it can be used for various organic pressure-sensitive adhe...
