Abstract

The invention discloses water-based white ink for surface treatment of a base material before code spraying. The water-based white ink comprises the following components by weight: 11 to 12 parts of awater-based acrylic emulsion, 0.3 to 0.5 part of a dispersing agent, 63 to 65 parts of an inorganic pigment, 5 to 10 parts of water, 25 to 30 parts of auxiliary agents, 0.1 to 0.3 part of a defoamingagent, and 0.2 to 0.4 part of a leveling agent, wherein the water-based acrylic emulsion comprises the following components by weight: 25 parts of butyl methacrylate, 40 parts of styrene, 20 parts ofbutyl acrylate, 10 parts of hydroxypropyl acrylate, 5 to 15 parts of water-soluble solid acrylic resin, 0.5 to 5 parts of an anionic emulsifier, 0.2 to 1.2 parts of ammonium persulfate, 0.5 to 5 parts of a coalescing agent, 0.1 to 1 part of a defoaming agent, 4 to 14 parts of ammonia water, and 40 to 70 parts of deionized water. According to the water-based white ink adopting the structure and used for surface treatment of the base material before code spraying, the water-based acrylic emulsion is used as a connecting material, and the coloring property and the adhesive force of a coating film can be kept, so that the water-based white ink is suitable for surface treatment of a non-polar base material code printing area; and meanwhile, volatilization of harmful substances is avoided by using water as a solvent.

Description

technical field [0001] The invention relates to an ink technology, in particular to a water-based white ink used for surface treatment of a substrate before coding and a preparation method thereof. Background technique [0002] Because the water-based inkjet ink is stable, non-flammable, and bright in color, and the water-based inkjet ink is formulated with water-based resin, which is soluble in water and can be diluted with water without organic solvents, so it can avoid air pollution and damage caused by solvent volatilization Employees' health issues, so it is an environmentally friendly ink. At the same time, because of its cheap price, it is suitable for printing on the surface of water-absorbing materials such as cartons and wood (because this material can absorb water, thereby forming the "adhesion" of the ink). After printing, it has good adhesion, quick drying, and strong water resistance. It is usually used in food, medicine, beverage and other industries, and it ...
