Abstract

The invention relates to the technical field of inks, particularly to an alkali-resistant aqueous binder and a preparation method thereof, and a beer label aqueous ink prepared by using the alkali-resistant aqueous binder, wherein the alkali-resistant aqueous binder is prepared from the following raw materials by weight: 15-30 parts of a modified epoxy resin, 20-30 parts of an acrylic mixing monomer, 10-30 parts of vinyl silane, 5-10 parts of a mixed emulsifier, 0.5-0.8 part of an initiator A, 0.1-0.5 part of a defoamer A, 0.1-0.5 part of a leveling agent, 0.5-1.5 parts of a neutralizing agent, and 100-130 parts of water, wherein the mixed emulsifier comprises a PA emulsifier, an epoxy emulsifier and a reactive emulsifier. According to the present invention, the alkali-resistant aqueous binder is alkali-resistant acrylic acid-epoxy emulsion, and has advantages of good alkali resistance, good water resistance, low/no VOC, fast drying, simple preparation, low cost and the like.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to an alkali-resistant water-based binder, a preparation method thereof and a beer label water-based ink prepared by using the same. Background technique [0002] In recent years, wine labels made of vacuum aluminum-coated paper have been widely used, and most of the beer labels are printed with solvent-based inks, such as POP inks and TSP inks. When the beer label requires beer bottles to be recycled, the ink printed on the surface of the label cannot fall off in the bottle washing tank when the recycled bottle is washed with lye, so that the label will not be deinked. There is an urgent need for a water-based beer label ink to replace traditional solvent-based inks in the market, but ordinary acrylic emulsions are not alkali-resistant, so it is of great significance to develop an alkali-resistant water-based binder that meets market demand. [0003] For example, Chinese patent CN102...
