Film stripping liquid for glass surface treatment and film stripping process

The invention provides a film stripping liquid for glass surface treatment and a film stripping process. The film stripping liquid is prepared from the following raw materials in parts by weight: 10-20 parts of an alkaline compound; 3 to 6 parts of a nonionic surfactant; 2-4 parts of an anionic surfactant; 5 to 8 parts of glycerol; 1 to 2 parts of 2-methylpyridine; 60 to 80 parts of water; wherein the alkaline compound is a mixture of sodium hydroxide, triethanolamine and sodium carbonate, and the weight part ratio of the sodium hydroxide to the triethanolamine to the sodium carbonate is (3-8): (1-2): (2-5). According to the film stripping liquid, the mixed alkaline compound in a specific proportion is adopted and matched with other raw materials, glass can be effectively removed while a film layer is not damaged, and the film stripping liquid has a certain cleaning effect on the surface of the glass. 本发明提供了一种玻璃表面处理用退膜液及退膜工艺，退膜液由包括如下重量份数的原料制备得到：碱性化合物10-20份；非离子表面活性剂3-6份；阴离子表面活性剂2-4份；丙三醇5-8份；2-甲基吡啶1-2份；水60-80份；
