Abstract

The invention discloses water-based silk screen ink and a preparation method thereof. The water-based silk screen ink comprises 70 to 75 percent of water-based polyurethane latex, 15 to 20 percent of pigment, 0.8 to 1.5 percent of antifoaming agent, 1.0 to 1.5 percent of dispersant, 0.5 to 1.0 percent of wetting agent, and 1.0 percent of thickening agent. The antifoaming agent is a mixture of polysiloxane or non-silicone amide and hydrocarbon, the dispersant is polyacrylic acid ammonium salt or polyacrylic acid sodium salt, the wetting agent is nonionic surfactant, the thickening agent is alkali-swelling acrylic ester copolymer, and the pigment is pearlied gold or silver paste. The preparation method comprises the following steps: A, firstly filtering the water-based polyurethane latex; B, adding the pigment, the antifoaming agent, the dispersant, the wetting agent and the thickening agent into the filtered water-based polyurethane latex; and C, fully stirring the mixture to obtain the ink. The water-based silk screen ink has the advantages of high temperature resistance, high adhesive strength and high card peeling strength, and is particularly suitable for printing card products.

Description

technical field [0001] The invention relates to a water-based screen ink, in particular to a data card water-based screen ink and a preparation method thereof. Background technique [0002] Water-based screen gold and silver ink for data cards is a kind of ink used for card screen printing. At present, the screen inks used in the card making industry are solvent-based inks. Aliphatic and aromatic solvents are used as diluents. It is used to adjust the viscosity and fluidity of the ink to achieve the best effect. However, during the printing and drying process of the ink, a large amount of harmful substances are produced due to a large amount of volatilization of the solvent, which not only affects the health of the operator, but also pollutes the surrounding environment, posing unsafe risks. [0003] At present, the common water-based inks in the market include water-based gravure inks, water-based flexographic inks, and water-based screen inks. These types of water-base...
