Acid-resisting etching protecting printing ink and its preparation method and construction method

The invention relates to an acid-resisting etching protecting printing ink and its preparation method and construction method. The acid-resisting etching protecting printing ink comprises modified epoxy acrylate, carboxylic acid polyester acrylate, pure acrylic ester, 2-phenoxy-ethyl acrylate, 1, 6-hexanediol diacrylate, 2-hydroxy-2-methyl-1-phenyl-1- acetone, 2, 4, 6- trimethylbenzoyl-diphenylphosphine oxide, inorganic fillers and flatting agent. The acid-resisting etching protecting printing ink is specialized in the industrial production of a touch screen, and has the advantage of resisting acid and not resisting alkali; during the industrialization process, the printing ink can resist acid etching fluid and temporarily protect the ITO glass manufacturing process of the touch screen; after completing the process, the printing ink can be rapidly isolated by alkali fluid, the ink isolating time is obviously shortened, and the production efficiency is improved. 本发明涉及种耐酸蚀刻保护油墨及其制备方法和施工工艺，所述耐酸蚀刻保护油墨包括改性环氧丙烯酸酯、羧
