Abstract

The present invention provides a polycarbonate release film, wherein the thin film layer comprises, by weight, 100 parts of PC, 10-15 parts of PTFE powder, 10-20 parts of TPX, 5-10 parts of nanometer silica, 3-5 parts of 3-aminopropyltriethoxysilane, 10-16 parts of butyl acrylate, 15-20 parts of methyl methacrylate, 1-2 parts of octadecyl methylacrylate, 10-20 parts of polyethylene glycol, 5-10 parts of natural latex, 0.3-0.5 part of a defoamer, and 0.3-0.5 part of a thickener. According to the present invention, the thin film layer of the release film uses the PC, the PTFE and the TPX as the compounding components and is added with the nanometer silica, and the prepared release film has characteristics of excellent peel strength, excellent water resistance, excellent mechanical property, excellent solvent resistance, excellent high temperature performance and excellent chemical resistance, and provides wide application range compared with the conventional release film.

Description

technical field [0001] The invention relates to a release film, in particular to a polycarbonate 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 w...
