Problems solved by technology

Along with a large amount of application of liquid crystal display, the demand of light-diffusing film is also more and more big, and traditional light-diffusing polyester film adds light-diffusing agent in manufacturing process, as a kind of PET light-diffusing release film announced by CN104962043, in film The layer always adds silicone light diffusing agent and various additives to achieve the purpose of light diffusion, but the silicone light diffusing agent is expensive and needs to be imported, and various additives added will also affect other properties of the PET release film

Abstract

The invention discloses a polyester release membrane for an optical membrane, comprising a polyester thin membrane and non-adhesive separator layer applied to at least one lateral surface of the polyester thin membrane.The non-adhesive separator layer is made by mixing and baking the following components according to parts by weight: trifluoroethyl methacrylate, vinytrimethoxysilane, isooctyl methacrylate, long-chained alkane, glycol methyl ether, a photo-condensing initiator, an ultraviolet absorbent, acrylate carbamate, octadecanol methacrylate, and 2,4'-toluene diisocyanate.The polyester release membrane requires no expensive organosilicon light diffuser to be added, and the release membrane with light diffusing capacity can be made by adding the acrylate carbamate, the photo-condensing initiator and the ultraviolet absorbent.

Description

technical field [0001] The present invention relates to the field of membranes. More specifically, the present invention relates to a polyester release film for an optical film. Background technique [0002] Because the release film has the advantages of isolation, filling, protection, and easy peeling, it is widely used in various fields such as electronics, communications, and machinery. [0003] The traditional polyester release film is to coat a layer of silicone oil on the surface of the polyester film to reduce the adhesion of the polyester film surface and achieve the release effect. Polyester release film has good adsorption and adhesion, and is widely used in packaging, printing, silk screen, pad printing, nameplate, membrane switch, flexible circuit, insulation products, circuit board, laser anti-counterfeiting, lamination, electronic , film for sealing materials, reflective materials, waterproof materials, medicine (plaster paper), sanitary paper, adhesive produ...
