Technical field
The present invention relates to printing technical field of ink, more particularly to a kind of printing water ink that durability is strong and its
Preparation method.
Background technique
Water-based ink is referred to as ink, and flexographic plate aqueous ink is also referred to as liquid ink, is by objects such as link stuff, pigment, auxiliary agents
The uniform slurry like material of matter composition.It is aqueous to have many advantages, such as that color representation power is good, adhesive force is good, oil resistant, to various stock materials
Material has wide applicability.Due to making dissolution carrier with water, water-based ink have it is safe and nontoxic harmless, non-ignitable not quick-fried, almost
Non-volatility organic gas generates significant Environmental Safety feature.Water-based ink is compared with solvent-based ink, water-based ink advantage
Be: (1) solvent-based ink can give out a large amount of low concentration VOC, since water used for water color ink makees dissolution carrier, so no matter
It is when being also used to printing, hardly to distribute volatile organic gases (VOC) to atmosphere in its production process.(2) by
In being free of aromatic hydrocarbon organic solvent so that the remaining noxious material of printed matter surface greatly reduces, cigarette, wine, food, beverage,
The sanitary conditions such as drug, toy for children require more to embody good healthy and safe property in stringent Packaging Printing Product.(3) by
In the intrinsic characteristic of water-based ink --- skeuomorph content is higher, can deposit in relatively thin ink film, therefore water-based ink dosage is few.
(4) use of water-based ink, which is avoided, encounters the shortcomings that open fire can explode using volatile organic solvent, improves work
The safety of industry environment ensures the health of contact, operator.Since water-based ink has above-mentioned excellent characteristic, send out at present
