Abstract

The invention provides a cleaning agent and a cleaning method of a Film film, and relates to the field of electronic equipment panel production. The cleaning agent comprises the following raw materials in percentage by weight: 2-7% of an alkaline auxiliary agent, 3-8% of a chelating agent, 7-13% of a wetting agent, 0.1-3% of a penetrating agent, 3-9% of an organic solvent and 62-82% of water. Thealkaline auxiliary agent is an alkaline salt and / or organic amine. By using the cleaning agent, the technical problems of damaging an ink functional layer and reducing the finished product rate of theFilm film when cleaning the coded Film film by using the existing strong alkaline cleaning agent can be relieved, and the purpose of improving the product yield rate in the cleaning process is achieved.

Description

technical field [0001] The invention relates to the field of production of electronic equipment panels, in particular to a cleaning agent and a film cleaning method. Background technique [0002] With the explosive development of mobile phone covers, 3D mobile phones have developed rapidly. Currently, in the glass back covers of 3D mobile phones, a large number of mobile phone manufacturers use a structure combining deco-film and glass substrates. [0003] Before the film film is bonded to the glass, it is necessary to prepare a glare decorative layer on the film film and perform coding treatment. The preparation of film usually consists of the following processes: wire drawing, electroplating NCVM, silk screen printing, laser coding, cleaning, laser cutting and inspection. Coding is for traceability of the film and for foolproofing. However, after silk screen printing and coding, a large amount of ink dust will remain on the surface of the film, and at the same time, dirt...
