Problems solved by technology

Water-based inks are especially suitable for packaging and printing products with strict hygienic requirements such as cigarettes, alcohol, food, beverages, medicines, and children's toys; and Staphylococcus aureus) have no obvious outstanding features, and when spraying environmentally friendly water-based ink on the board, the traditional process is to use a spray gun or a disc atomizer to disperse into uniform and fine particles with the help of pressure or centrifugal force. Fog droplets, a coating method applied to the surface of the object to be coated, this method not only pollutes the environment, is not conducive to human health, but also wastes paint

Abstract

The invention discloses an environment-friendly waterborne ink and a preparation process thereof. The ink is prepared from, by weight, 60-70 parts of an epoxy-modified acrylic resin, 3-5 parts of an antibacterial agent, 1-3 parts of long oil alkyd resin, 1-3 parts of an antioxidant, 1-2 parts of sodium dodecyl sulfate, 5-10 parts of waterborne organic pigment, 0.5-1 part of an anti-foaming agent,0.5-1 part of a waterborne leveling agent, 0.5-1 part of a waterborne wax emulsion, 0.5-1 part of ammonia water, 90-100 parts of deionized water and 30-40 parts of ethyl alcohol. The prepared environment-friendly waterborne ink has the obvious prominent characteristics in the aspects of coloring power, ultraviolet reflectivity, adhesion and the antibacterial property, by means of the spraying androlling process, the adhesion of the ink is higher, and the pollution is less than that of a conventional method of only spraying the ink.

Description

technical field [0001] The invention relates to the technical field of preparation of environment-friendly water-based ink, in particular to an environment-friendly water-based ink and a preparation process thereof. Background technique [0002] Water-based ink Water-based ink water-based ink is referred to as ink for short, and flexographic water-based ink is also called liquid ink. It is mainly made of water-soluble resin, organic pigment, solvent and related additives through compound grinding. Water-based inks are especially suitable for packaging and printing products with strict hygienic requirements such as cigarettes, alcohol, food, beverages, medicines, and children's toys; and Staphylococcus aureus) have no obvious outstanding features, and when spraying environmentally friendly water-based ink on the board, the traditional process is to use a spray gun or a disc atomizer to disperse into uniform and fine particles with the help of pressure or centrifugal force.
