Water-based glass ink and preparation method thereof

The invention relates to the field of ink and discloses water-based glass ink and a preparation method thereof. The water-based glass ink is prepared from the following raw materials in parts by weight: 50-65 parts of a water-based modified acrylic polymer and 30.5-55 parts of an auxiliary material; and the auxiliary material is prepared from the following components in parts by weight: 1-5 parts of a coupling agent, 2-8 parts of a curing agent, 0.5-1 part of a defoaming agent, 1-3 parts of a flatting agent, 8-10 parts of an organic pigment, 6-8 parts of inorganic filler and 12-20 parts of a solvent. The water-based glass ink is good in solubility in water; the solvents with relatively high toxicity, such as benzene, are not used; the preparation reaction temperature is low; the problem of environmental pollution is solved; and the environmental pressure on an external environment and the pollution on a labor environment of a worker are relieved to a great extent. The water-based glass ink is good in adhesive
