Problems solved by technology

Take metal (effect) ink as an example. Common binders, additives and fillers are used in this type of ink. After printing, there will be defects such as poor metal texture and dark color of the printed product. In addition to affecting the aesthetic effect, the anti-counterfeiting strength will also be affected. discount
Canadian patent (CA2280550) discloses a kind of bright metallic engraving gravure printing ink, and its research result thinks that the filler in the ink hides the brightness of metal particle, therefore does not contain any filler in its ink formula, but in order to solve the resulting The problem of poor ink stability is that the ink is designed as a two-component separate storage, and it is mixed and prepared before use, which also brings production limitations; in addition, the bright metal engraving gravure ink needs to be heated to dry after printing. The linking material used is a commercially available linking material (as a roller rubbing engraving gravure gold ink, the acid value is 45-80mgKOH / g); for the printability of engraving gravure metal ink for banknotes, water rubbing does not rub dirty properties, pattern reproducibility and physical and chemical resistance of the resulting printed matter have not been reported

Embodiment A1

[0055] 10.1 parts of tower oil fatty acid, 6.8 parts of linoleic acid, 7.8 parts of glycerol, 3.4 parts of pentaerythritol, 5.7 parts of phthalic anhydride and an appropriate amount of xylene were heated to 200°C under the protection of nitrogen, and kept at a temperature of 200°C. In esterification, the acid value of the system is measured during the reaction, and when the acid value reaches 4, the temperature is lowered to obtain o-phenylalkyd resin, and the oil degree of the resin is 55%. Get a total of 32 parts of above-mentioned resins, add 45 parts of dodecane solvents, 10 parts of dipropylene glycol dimethyl ether solvents are warming up to about 80 ℃, drip 7 parts of toluene diisocyanate (TDI) and be incubated for 2 hours to a viscoelastic ratio of 4, Add 0.05 part of dibutyltin dilaurate and 0.5 part of methanol, and after holding for 1 hour, adjust the product with about 4-5 parts of solvent to a viscosity of 12 Pa.S / 40°C and a viscoelasticity ratio of 6. That is, ve...

Embodiment B1

[0063]Add 30 parts of tung oil, 25 parts of sesame oil, 10 parts of glycerol, and 4 parts of pentaerythritol to the reaction kettle, add 0.05 part of catalyst lithium hydroxide when the temperature reaches 160 ° C, and under the protection of nitrogen, transesterification reaction occurs at 240 ° C, and the detection After the alcoholysis is qualified (the reaction product: 95% ethanol = 1:5, the solution is clear and transparent), 25 parts of isophthalic acid, 0.02 part of catalyst zinc oxide and an appropriate amount of methyl isobutyl ketone medium solvent are added, and the ester is kept at 230 ° C. The reaction was stopped when the acid value reached 15, and the viscosity was adjusted to 6.2 Pa.S / 40°C with a dodecane solvent (about 6 parts) to obtain iso-benzyl alkyd resin B1 with an oil degree of 62%.

Abstract

The invention provides an improved water-washing non-smearing curved gravure ink and a preparation method thereof. The components of the improved water-washing non-smearing curved gravure ink are as follows: 20 to 70 percent of linking marerials, 8 to 50 percent of dye, 1 to 8 percent of solvent, 2 to 28 percent of nanometer padding, 0 to 3 percent of driers, 2 to 12 percent of wax, 1 to 7 percent of surface active agents, 0 to 8 percent of directional agents as well as 0 to 5 percent of adhesion promoter; wherein, the acid value of linking marerials is 10 to 30mgKOH / g and the viscosity is 4 to 16Pa.S / 40DEG C. The aspects of the printability, the color characteristics of a printed product and the stability of the ink of the water-washing non-smearing curved gravure ink obtained by the invention by using a low-acid value linking material composite and the corresponding padding and addition agents are effectively improved, the anti-fake level of the printed product can be improved in particular. The improved water-washing non-smearing curved gravure ink can be a water-washing non-smearing curved gravure metal ink, a water-washing non-smearing curved gravure effective ink or a water-washing non-smearing curved gravure anti-fake ink.

Description

technical field [0001] The invention relates to an engraving gravure ink with improved performance, which is not rubbed and stained by water, and a preparation method thereof, belonging to the technical field of printing. Background technique [0002] In order to deal with counterfeiters, some advanced anti-counterfeiting technologies are applied to banknotes, which greatly improves the anti-counterfeiting level of banknotes. However, out of personal interests, counterfeiters still use various means to forge banknotes and disrupt the financial order. Therefore, effectively improving the mass anti-counterfeiting characteristics of banknotes has become a research hotspot in the field of banknote printing. The engraving gravure printing process is an important and unique anti-counterfeiting process used in the field of anti-counterfeiting printing, including the banknote printing industry. feature. [0003] The engraving gravure ink has special printing process and requireme...
