Abstract

The invention discloses single-component printing ink used for 3C glass and a water-based printing ink coating. The single-component printing ink used for the 3C glass comprises the following components of, in parts by weight, 25-45 parts of organic and inorganic compound water-based resin, 5-10 parts of pigment, 32-55 parts of filler, 10-25 parts of water, 1-5 parts of blocked water-based curingagent and 0.01-1.0 part of assistant. The organic and inorganic compound water-based resin used for producing the single-component printing ink used for the 3C glass is good in chemical resistance, excellent in ultraviolet light aging resistance and good in 3C glass adhesion, and has ultra-high surface hardness and low thermal expansion and contraction. In a high-temperature curing process, hydroxy or carboxyl in the organic and inorganic compound rein and the blocked water-based curing agent are subjected to cross-linking reaction to form a Interpenetrating network structure, performance of the components are brought into full play, and the printing ink coating is formed on the surface of the 3C glass. The blocked water-based curing agent can also provide reasonable thermocuring speed sothat the requirements of short thermocuring time of the industry of 3C glass can be met by the printing ink.

Description

Technical field [0001] The present invention relates to the field of inks, and in particular, to a one-component ink 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] Currently, the two-component heat-curing solvent-based decorative ink commonly used in the industry requires a long time to adjust the oil before use. After adjustment, the ink has a short service life, the frequency of oil adjustment is high, and a lot of waste ink is generated, 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 higher production costs. At the same time, because a large amount of waste ink is produced, subsequent treatment is required, causing secondary pollution to the environment. The carrier in the ink uses a large amount of solvent. During the curing process ...
