Abstract

The invention relates to an acid-resistant etching protective ink and its preparation method and construction process. The acid-resistant etching protective ink includes modified epoxy acrylate, carboxylic polyester acrylate, pure acrylate, and 2-phenoxyethyl acrylic acid ester, 1,6-hexanediol diacrylate, 2-hydroxy-2-methyl-1-phenyl-1-acetone, 2,4,6-trimethylbenzoyl-diphenylphosphine oxide, Inorganic filler and leveling agent. The acid-resistant etching protection ink of the present invention is specially used for the industrial production of touch screens, and has the advantages of being acid-resistant and not alkali-resistant. Rapid deinking with lye can significantly shorten the deinking time and improve production efficiency.

Description

technical field [0001] The invention relates to the field of inks, in particular to an acid-resistant etching protection ink and a preparation method and a construction method thereof. Background technique [0002] With the rapid development of modern technology, touch screen has become the first choice of many electronic display products. Capacitive touch screens have become the mainstream touch screen technology in the world. For capacitive touch screens, many manufacturers currently use G+G (glass-to-glass bonding) or G+F (glass-to-film bonding) processes. The acid etching process is used to make ITO circuit glass. The acid etching process requires special ink to be printed on the circuit that needs to be protected by the ITO glass, and then the unprotected area is corroded by the acid etching solution, and then the lye is used to remove it. After the ink is removed, a touch screen glass with ITO lines is formed. However, the ink that solves this problem in the market i...
