Abstract

The invention provides an insulating release film which comprises a thin film layer. The thin film layer is prepared from materials including PET (polyester), PC (propylene carbonate), OPP (o phenylphenol), PBT (polybutylece terephthalate), polyetherimide, phenolic resin, epoxy resin, polyurethane, polymide, talcum powder, 2-ethyl methacrylate, organic montmorillonite, ethylene glycol, a silane coupling agent, an antioxygen, a light stabilizer, a defoamer and a thickener. The insulating release film is good in insulating performance, peeling strength and tensile strength, smooth and clean in surface, good in heat stability and heat shrinkage, resistant to light aging and reusable; besides, the insulating release film is environment friendly and non-toxic, simple in synthetic method, convenient in operation, moderate in condition and suitable for industrial production.

Description

technical field [0001] The invention relates to a release film, in particular to an insulating 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 wid...
