Abstract

The invention discloses a PVC (polyvinyl chloride) release film. The PVC release film comprises a thin film layer material and a functional release agent layer, wherein the functional release agent layer is coated onto the thin film layer material. Compared with the existing PVC release film, the PVC release film has the advantages that under the synergetic action of components, the mechanical property of the thin film layer material is greatly improved; by adding a certain mass ratio of 600-mesh shell powder and 30nm nanometer diatomite, under the synergistic action of treated fortune paulownia wood powder, the impact strength, bending strength and elasticity are greatly improved; the anti-static effect is good, the dust is not sucked, the photothermal aging-resistant property is strong, and the weather-resistant property is better.

Description

technical field [0001] The invention relates to the field of release films, in particular to a PVC release film. Background technique [0002] 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 silicon release agent on the surface of the film material, such as PVC, PE, OPP, etc.; Various organic pressure-sensitive adhesives (such as hot melt adhesives, acrylic adhesives, and rubber-based pressure-sensitive adhesives) can exhibit extremely light and stable release forces. [0003] Because the release film has the advantages of isolation, filling, protection, and easy peeling, it is widely used in various fields such as electronics...
