Abstract

The invention provides a fluorine release paint, and a fluorine release film and a preparation method thereof. The fluorine release paint is prepared from the following raw materials: 8 wt% to 60 wt%of fluorocarbon resin, 0.1 wt% to 30 wt% of a fluorine release agent, 0.2 wt% to 20 wt% of a curing agent and 25 wt% to 90 wt% of an organic solvent. The fluorine release film comprises a substrate and a fluorine release coating arranged on the surface of the substrate, wherein the fluorine release coating is prepared from the fluorine release paint described in a technical scheme in the invention. Compared with the prior art, the fluorine release film provided by the invention adopts the fluorine release coating prepared from the fluorine release paint with specific composition, realizes better interaction under the condition of a specific structure, has excellent high-temperature resistance and release properties, and is free of any silicon transfer.

Description

Technical field

[0001] The invention relates to the technical field of release films, and more specifically, to a fluorine release coating, a fluorine release film and a preparation method thereof. Background technique

[0002] Release film refers to a special film with a lower surface energy than conventional films. The release film has no stickiness or slight stickiness after contacting with certain materials under limited conditions. Normally, in order to increase the release force of the plastic film, a release agent coating treatment is applied to the surface of the film (PET, PE, OPP, paper, etc.), so that it is suitable for various pressure-sensitive adhesives (such as silicone series). Pressure sensitive adhesives, acrylic pressure sensitive adhesives and rubber pressure sensitive adhesives) exhibit extremely light and stable release force. According to the different viscosity of the isolation pressure-sensitive adhesive, the release force should be adjusted accordingly...
