一种PET光扩散离型膜
摘要：
本发明提供给了一种PET光扩散离型膜，薄膜层按重量份配比包括如下组分：PET 100份；PP 8-12份；有机硅光扩散剂 3-5份；纳米二氧化硅 5-7份；3-氨丙基三乙氧基硅烷 3-5份；α-氰基丙烯酸乙酯 10-16份；丙烯酸-2,3-环氧丙酯15-20份；甲基丙烯酸十八醇酯 1-2份；聚乙二醇 10-20份；乙醇 10-20份；去离子水 20-30份；天然乳胶 5-10份；消泡剂 0.3-0.5份；增稠剂0.3-0.5份。本发明的离型膜，加入光扩散剂和纳米二氧化硅，其剥离强度、力学性能优越，同时还具有很好地光扩散性能，相较于常规的离型膜而言，其应用范围更为广泛。
摘要（英）：

The present invention provides for a PET photodiffusion release film, wherein the thin film layer comprises, by weight, 100 parts of PET, 8-12 parts of PP, 3-5 parts of an organosilicon photodiffusion agent, 5-7 parts of nanometer silica, 3-5 parts of 3-aminopropyltriethoxysilane, 10-16 parts of ethyl alpha-cyanoacrylate, 15-20 parts of 2,3-epoxypropyl acrylate, 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. The release film of the present invention is added with the photodiffusion agent and the nanometer silica, such that the peel strength and the mechanical property are excellent, the good photodiffusion property is good, and the application range is wide compared with the routine release film.
