Abstract

The invention belongs to the technical field of labels, and particularly discloses a water-based emulsion for a beer label and a preparation method thereof. The water-based emulsion is prepared from the following components in parts by weight: a phase A of 80-150 parts of acrylic resin and 250-350 parts of deionized water, a phase B of 1-10 parts of a reactive emulsifier and 3-5 parts of deionizedwater, a phase C of 0.5-1.5 parts of an initiator and 1-15 parts of deionized water, a phase D of 10-25 parts of a compound composed of diacetone acrylamide and adipic acid dihydrazide and 5-15 partsof deionized water, a phase E of 250-400 parts of mixed reactants and a phase E1 of 20-40 parts of mixed reactants, wherein the mass ratio of the diacetone acrylamide to the adipic acid dihydrazide is 2-3:1. The water-based emulsion belongs to the self-crosslinking type and has excellent alkali resistance, adhesive force and bottle sticking glue resistant performance, the problems that in the prior art, a beer label coating is poor in alkali resistance, poor in bottle sticking glue resistance and poor in water resistance, the wet adhesive force is poor, and an original coating is low in viscosity and difficult to clean can be solved, the water-based emulsion can be better recycled and is more environmentally friendly, and the pollution to the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of labels, in particular to an aqueous emulsion used for beer labels and a preparation method thereof. Background technique [0002] Since water-based paint does not contain volatile organic compounds, it greatly reduces the emission of volatile organic compounds (VOC), thereby reducing air pollution. It is applied to make labels, which not only improves the environment for operators and the overall environmental quality, but also benefits workers. healthy. In addition, it can not only reduce fire hazards and hidden dangers caused by static electricity and flammable solvents, but also reduce residual toxicity on the printing surface and facilitate cleaning of printing equipment. Therefore, water-based coatings emerged as the times require to solve the problems of volatile organic compound emissions caused by solvent-based coatings. They have outstanding environmental protection advantages and are considered...
