Abstract

The present invention provides an environmental protection type aqueous release film, which comprises a thin film layer and a release layer positioned on the thin film layer, wherein the release layer comprises, by weight, 35-45 parts of an aqueous polyethylene wax emulsion, 45-55 parts of an aqueous polyurethane emulsion, 20-30 parts of an aqueous modified polyvinyl alcohol solution, 5-10 parts of natural latex, 3-5 parts of a silane coupling agent, 0.3-0.5 part of a defoamer, and 0.3-0.5 part of a thickener, and the aqueous modified polyvinyl alcohol solution comprises, by weight, 100 parts of polyvinyl alcohol, 700-800 parts of deionized water, and 30-50 parts of modified calcium carbonate. The release film of the present invention is the aqueous environmental protection type release film, has characteristics of good peel strength and good stretching strength, and is the release film having the good comprehensive performance.

Description

technical field [0001] The invention relates to a release film, in particular to an environment-friendly water-based 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 e...
