Problems solved by technology
In the water-based inks printed in the prior art, because the surface tension of water molecules is very large, the water-based inks are difficult to wet, dry slowly, have poor adhesion, gloss, and unsatisfactory hydrolysis resistance. The stability of the ink is not high and it is harmful to the skin after printing. low affinity

Embodiment 1
[0018] The water-based environmental protection non-sense screen printing ink of the present embodiment adopts raw materials and mass fractions: 50-60% of water-based aliphatic polyurethane resin, 20-30% of water-based polycarbonate polyurethane resin, 1-3% of defoamer, wetting Agent 1-3%, thickener 1-3%, humectant 5-10%, pigment paste 20-30%.
[0019] The most preferred raw materials and mass fractions are: 50% water-based aliphatic polyurethane resin, 20% water-based polycarbonate polyurethane resin, 2% defoamer, 1% wetting agent, 1% thickener, 5% humectant, pigment Color paste 21%.
[0020] The defoaming agent is polydimethylsiloxane, the wetting agent is polysiloxane, the thickener is polyurethane, the humectant is polyethylene glycol, and the pigment paste includes carbon black, phthalocyanine blue, pigment red 254, Feisdocken Yellow GR, Permanent Violet RL, Titanium Dioxide. By adding polyethylene glycol and selecting polycarbonate polyurethane, the drying speed during...

The invention provides water-base environment-friendly non-inductive silk-screen ink. The ink is prepared from the following raw materials, in percentage by mass: 50-60% of water-base aliphatic polyurethane resin, 20-30% of water-base polycarbonate polyurethane resin, 1-3% of defoaming agent, 1-3% of wetting agent, 1-3% of thickening agent, 5-10% of humectant and 20-30% of pigment color paste. Thepreparation method comprises the steps that firstly water-base aliphatic polyurethane resin and water-base polycarbonate polyurethane resin are put into a stirring tank and stirred, then the defoaming agent, the wetting agent and the humectant are added and stirred, then the pigment color paste is added and stirred, finally the thickening agent is added and stirred, and the temperature is controlled to be 5-40 DEG C in the stirring process. The preparation method can improve the drying speed of the ink in the printing process and the affinity of the ink to the skin after the ink is dried. Theink has the excellent skin feeling, softness, adhesiveness, glossiness and hydrolysis resistance, has the high stability and is environmentally friendly. The preparation technology is simple and easyto operate.
Description
technical field [0001] The invention relates to the technical field of ink printing, in particular to a water-based environmental protection non-sensitivity screen printing ink and a preparation method thereof. Background technique [0002] The biggest difference from solvent-based inks is that the solvents used in water-based inks are water and a small part of ethanol, and there is almost no volatile organic gas, which greatly reduces VOC emissions and prevents air pollution. It can completely eliminate the harm of certain toxic substances in solvent-based inks to the human body and the pollution of packaged goods. The most popular among water-based inks is flexo water-based ink. Initially, flexographic water-based inks were only used for printing paper bags, and then the scope of use gradually expanded. In the United States, most of today's flexographic water-based inks are used in the packaging and printing field, accounting for about 85%, such as various plastic films,...
