[0012] But the natural antibacterial agent that adopts in the above-mentioned method is the composition of oil solubility, no matter in the process that antibacterial agent is mixed, still needs to add surfactant in the process of preparing printing ink, increases its dissolving effect, and prepared Ink does not have the effect of reducing heavy metal content
The antibacterial water-based ink prepared by adopting the above-mentioned technical scheme still has certain defects in organic content, stable properties, heavy metal content, anti-oxidation and antibacterial properties, etc. Therefore, it is urgent to develop a low organic content and stable properties. For traditional water-based inks, the content of heavy metals is low, and it is an antibacterial water-based ink with excellent anti-oxidation and antibacterial properties

Abstract
The invention discloses antibacterial water-based ink and a preparation method thereof. The antibacterial water-based ink comprises components in parts by weight as follows: 20-60 parts of an acrylic resin liquid, 10-30 parts of organic pigments, 10-20 parts of deionized water, 15-20 parts of ethyl alcohol, 0-10 parts of an antibacterial agent and 0-2 parts of filler and an auxiliary, wherein the antibacterial agent is one or more of nano-copperoxide, nano-cuprous oxide, nano-copper, nano-silver or nano-gold containing functional surface groups. The antibacterial agent is modified and is enabled to contain the functional surface groups, so that hydrophilicity of the antibacterial water-based ink is improved, and the stability of the antibacterial water-based ink is improved; besides, the antibacterial agent contains the functional surface groups, and accordingly, the antibacterial water-based ink has excellent oxidation resistance and antibacterial performance, and the content of heavy metal is low.
Description
technical field [0001] The invention belongs to the technical field of ink, and in particular relates to an antibacterial water-based ink and a preparation method thereof. Background technique [0002] With the development of social economy, the printing industry has gradually become a symbol to measure the modernization level of a country. However, while the printing industry is developing, it has caused a lot of environmental pollution, of which organic volatiles are the main source of pollution. Therefore, the green and environmental protection products of the ink industry have received more and more attention and become the main development direction. Water-based ink uses water as the main solvent, which has almost no pollution of volatile organic compounds, greatly reduces the risk of environmental pollution, and effectively avoids health hazards to producers and users. At the same time, due to the low price of water, it has the advantage of low cost. [0003] At pres...
