TPX (methyl pentene copolymer) release film

Abstract

The invention provides a TPX (methyl pentene copolymer) release film. The TPX release film comprises a thin film layer; the thin film layer is prepared from the following raw materials in parts by weight: TPX, PC (Polycarbonate), 2-ethyl methacrylate, polyurethane, polyimide, polyetheretherketone fibers, carbon fibers, organic montmorillonite, ethylene glycol, a silane coupling agent, an antioxidant, a light stabilizer, a de-foaming agent and a thickener; the TPX release film has a flat and smooth surface and has good peeling strength and tensile strength; secondly, the TPX release film has good thermal stability and thermal shrinkage rate, can resist light aging and can be repeatedly used for a plurality of times; furthermore, the TPX release film provided by the invention is environment-friendly and has no toxin; a synthesis method is simple, is simple and convenient to operate, has moderate conditions and is suitable for industrial production.

Description

technical field [0001] The invention relates to a release film, in particular to a TPX 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

[0005] However, the existing TPX release film has poor heat sealing performance, low thermal shrinkage rate, is not easy to recycle, and its mechanical properties cannot meet the needs of the industry.
