Abstract

The present invention provides a PET release film, wherein the thin film layer comprises, by weight, 100 parts of PET, 8-12 parts of PP, 15-20 parts of barium sulfate, 15-20 parts of titanium dioxide, 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, 10-20 parts of ethanol, 20-30 parts of deionized water, 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 release film, the thin film layer is added with the barium sulfate and the titanium dioxide inorganic filler, such that the prepared release film has characteristics of excellent adhesion (peel strength), excellent mechanical property, good light-reflecting property, and wide application range.

Description

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