Embodiment 1-6

[0044]

[0045] The ink of Example 3 was printed on the cigarette inner packaging paper, and the paper’s performance indicators were as follows after being inspected by the National Quality Supervision and Inspection Center for Printing and Decoration Products:

[0046]

Embodiment 7-12

[0048]

[0049]

[0050] The waterproof and anti-seepage mechanism of the water-soluble gold and silver ink of the present invention is as follows: the acrylic resin in the emulsifier and the nano-scale silicon dioxide are synthesized into a colloid, which is then mixed with gold and silver powder and various additives to form an emulsion. The emulsion is then coated on suitable base paper, penetrates into the gaps of paper fibers, and forms a waterproof and impermeable film on the paper. That is, the packaging paper printed with the ink of the present invention has a waterproof and impermeable function. In the same way, this water-soluble gold and silver ink can also be used for the finishing of other objects.

[0051] The preparation method of the water-soluble gold and silver ink provided by the present invention is as follows:

[0052] 1. Emulsification reaction

[0053] ① Feeding and heating: Add a certain amount of water to the reactor and start stirring, weigh the acryl...

Abstract

This invention relates to a method for preparing water-soluble Au / Ag ink, which comprises: Au / Ag powder 20-30 wt.%, acrylic acid emulsion 55-65 wt.%, 15% polyvinyl alcohol 4-6 wt.%, gaseous SiO2 1-3 wt.%, dispersant 2-4 wt.%, wetting agent 0.3-1.0 wt.%, film-forming agent 3-5 wt.% and antifoam 0.2-0.4 wt.%. The water-soluble Au / Ag ink has such advantages as high water leakage resistance, high adhesiveness, high corrosion resistance, high electrostatic resistance, good anti-aging capacity, no color change, no fading, simple application process, no toxicity to operators, no environmental pollution, no flammability and no explosion. The water-soluble Au / Ag ink can be used to paint packages of cigarette and food as a substitute for Al / Pt composite paper.

Description

Technical field [0001] The invention relates to an ink used in the printing industry, in particular to a water-soluble gold and silver ink and a preparation method thereof. Background technique [0002] Due to the different solvents used, inks are divided into water-soluble inks and solvent-based inks. The inner liner paper for cigarette packaging is printed with a layer of gold ink or silver ink on the paper base. The traditional gold and silver inks are solvent-based inks. The solvent is flammable benzene or benzene compounds. Some products also contain formaldehyde, which is volatile and highly polluting. A large amount of toxic residues will be produced on the printed matter, and the function is single. . There are many papers that cannot be given some special functions after printing, such as waterproof and mildew proof. To solve these problems, it is necessary to develop a new type of printing material that is non-toxic, tasteless, and has special functions such as waterpro...
