Abstract

The invention provides an acid-resistant film with good stability, which sequentially includes a base film, an adhesive layer and a release layer. The adhesive layer is at least one of natural rubber adhesive, ethylene-propylene rubber adhesive, fluorine rubber adhesive, chlorinated polyethylene rubber adhesive, styrene-butadiene rubber adhesive, butyl rubber adhesive, and neoprene adhesive. The release layer is selected from PET release film or PO release film. The invention provides an acid-resistant film with good stability and a preparation method thereof. The invention effectively improves the adhesive force of the adhesive layer of the acid-resistant film and enhances the toughness of the adhesive layer by adding the acidified multi-walled carbon nanotubes, so that the acid-resistant film has good acid-resistant solution immersion and prevents residual glue residue effects. The acid-resistant film prepared by the invention has good cohesiveness, acid resistance, good overall stability and no glue residue after use. The preparation method of the invention is simple and convenient, has strong repeatability, is beneficial to large-scale production, and has great significance for the development of flat panel display technology.

Description

technical field [0001] The invention belongs to the field of acid-resistant membranes, and in particular relates to an acid-resistant membrane with good stability and a preparation method thereof. Background technique [0002] At present, with the continuous development of science and technology, flat panel display technology has higher and higher requirements for OLED displays, especially the requirements for thinner and lighter OLED displays. Among them, the single-sided thinning process of display glass has become an important process means for various terminal displays to achieve light weight. [0003] Touch screen glass used in OLED displays is a glass product often used for lightweighting. When reducing the weight of touch screen glass for OLED displays, it is necessary to protect the surface with the ITO circuit and thin the other side. In the existing technology, there are mainly two types of glass thinning methods: spraying thinning and immersion thinning. Among t...
