Abstract
The invention provides a photodiffusion release film. The photodiffusion release film comprises a film layer, wherein the film layer contains the following raw materials in parts by weight: TPX, PC, PFA, PBT, nano barium sulfate, nano-silica, polyetherimide, phenol-formaldehyde resin, polyurethane, polyimide, 2-ethyl methacrylate, organic montmorillonite, ethylene glycol, a silane coupling agent, an antioxidant, a photostabilizer, an antifoamer and a thickener. The photodiffusion release film has an excellent optical diffusion effect and has good peeling strength and tensile strength; secondly, the photodiffusion release film is flat and smooth in surface, has good thermal stability and thermal shrinkage ratio, can resist photoaging and can be reused repeatedly; in addition, the photodiffusion release film provided by the invention is environmentally friendly and non-toxic, the synthesis method is simple, is simple and convenient in operation and moderate in condition and is applicable to industrial production.
Description
technical field [0001] The invention relates to a release film, in particular to a light diffusion 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...
