Abstract

The invention discloses a one-component ink for 3C glass and a water-based ink coating. The one-component ink for 3C glass comprises the following components: in parts by weight, organic-inorganic composite water-based resin 25-45 5-10 parts of pigments, 32-55 parts of fillers, 10-25 parts of water, 1-5 parts of closed water-based curing agents and 0.01-1.0 parts of additives. The one-component ink for 3C glass of the present invention uses an organic-inorganic composite water-based resin, which has good chemical resistance, excellent UV aging resistance, good adhesion to 3C glass, high surface hardness, and low heat resistance. Expansion and contraction. During the high-temperature curing process, the hydroxyl group or carboxyl group in the organic-inorganic composite resin undergoes a cross-linking reaction with the closed water-based curing agent to form an interpenetrating network structure, fully exerting the performance of each component, and forming an ink coating on the surface of 3C glass. The closed water-based curing agent can also provide a reasonable thermal curing speed to ensure that the ink can meet the short thermal curing time requirements of the 3C glass industry.

Description

technical field [0001] The invention relates to the field of inks, in particular to a one-component ink used for 3C glass. In addition, the present invention also relates to a water-based ink coating comprising the above-mentioned one-component ink for 3C glass. Background technique [0002] At present, the two-component heat-curing solvent-based decorative ink commonly used in the industry needs a long time to adjust the oil before use. After the adjustment, the service life of the ink is short, the frequency of oil adjustment is high, and the waste ink produced is more, which needs to be disposed of. There is also a lot of waste oil, the production efficiency is relatively low, and the ink loss is large, resulting in high production costs. At the same time, because more waste ink is produced, follow-up treatment is required, causing secondary pollution to the environment. The carrier in the ink uses a large amount of solvents. During the curing process of the ink, VOC em...
