PVC release film

Abstract

The invention provides a PVC release film. The PVC release film comprises a thin film layer which comprises the following raw materials by weight: PVC, TPX, PP, 2-ethyl methacrylate, nano-barium sulfate, polyether imide, phenolic resin, polyarylester, carbon fiber, organic montmorillonite, ethylene glycol, a silane coupling agent, an antioxidant, a light stabilizer, a defoamer and a thickener. The PVC release film has a smooth and clean surface and good peel strength and tensile strength; secondly, the PVC release film has good heat stability and heat shrinkage rate, is capable of resisting light aging and can be repeatedly used; and the PVC release film has relatively balanced comprehensive performance and extremely good water resistance, solvent resistance, chemical resistance, corrosion resistance, temperature resistance, weather resistance and adhesiveness. Besides, the PVC release film provided by the invention is environmentally friendly and nontoxic, a synthetic method is simple, the operation is simple and convenient, conditions are mild, and the synthetic method is applicable to industrial production.

Description

technical field [0001] The invention relates to a release film, 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, silliconfilm, release film, release. 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 (silicone) release agent on the surface of the film material, such as PET, PE, OPP, etc.; It can show extremely light and stable release force for various organic pressure-sensitive adhesives (such as hot-melt adhesives, acrylic adhesives and rubber-based pressure-sensitive adhesives). [0003] Because the release film has the advantages of isolation, filling, protection, and easy peeling, it is widely used...

AI Technical Summary

Problems solved by technology

[0004] PVC release film has a wide range of applications, but the existing PVC release film has poor heat sealing performance, low heat shrinkage, single function, is not easy to recycle, and its mechanical properties cannot meet the needs of industry.
