Embodiment A1

[0052] 10.1 parts of tower oil fatty acid, 6.8 parts of linoleic acid, 7.8 parts of glycerin, 3.4 parts of pentaerythritol, 5.7 parts of phthalic anhydride and an appropriate amount of xylene are heated up to 200 ° C under the protection of nitrogen, and the temperature is kept Esterification, measuring the acid value of the system during the reaction, and cooling down when the acid value reaches 4, to obtain an ortho-phenyl alkyd resin with an oil degree of 55%.

[0053] Take a total of 32 parts of the above resin, add 45 parts of dodecane solvent, 10 parts of dipropylene glycol dimethyl ether solvent and heat up to about 80°C, add 7 parts of toluene diisocyanate (TDI) dropwise, and keep it warm for 2 hours until the viscoelastic ratio is 4 , add 0.05 part of dibutyltin dilaurate and 0.5 part of methanol, keep warm for 1 hour, use about 4-5 parts of solvent to adjust the product to a viscosity of 12Pa.S / 40℃, and a viscoelastic ratio of 6. That is, the vehicle component A1 is ...

Embodiment A2-A11

[0055] The preparation method is the same as in Example 1, and the reaction materials and dosage ratios are shown in Table 1.

Embodiment B1

[0061] Add 30 parts of tung oil, 25 parts of flax oil, 10 parts of glycerin, and 4 parts of pentaerythritol into the reaction kettle. When the temperature reaches 160°C, add 0.05 parts of catalyst lithium hydroxide, and the transesterification reaction occurs at 240°C under the protection of nitrogen. After the alcoholysis is qualified (reaction product: 95% ethanol = 1:5, the solution is clear and transparent), add 25 parts of isophthalic acid, 0.02 parts of catalyst zinc oxide and an appropriate amount of methyl isobutyl ketone as a medium solvent, and keep warm at 230 ° C. When the acid value reaches 15, the reaction is stopped, and the viscosity is adjusted to 6.2 Pa.S / 40°C with a dodecane solvent (about 6 parts) to obtain m-phenyl alkyd resin B1 with an oil degree of 62%.

Abstract

The invention provides a composite of linking materials, which is suitable for a water-washing non-smearing curved gravure ink. The composite consists of the following three components: component A: isocyanate-modified alkyd with a weigh percentage of 10 to 70 percent; component B: m-phenylene alkyd and / or modified m-phenylene alkyd with a weight percentage of 5 to 40 percent; component C: at least one phenolic resin oil modified by seed fat with a weight percentage of 10 to 70 percent; besides, the acid value of the composite of the linking materials is 10 to 30mgKOH / g and the viscosity is 4 to 16Pa.S / 40DEG C. The invention also provides a water-washing non-smearing curved gravure ink which mainly adopts the linking materials which improve the storage stability and the printing property of the ink, obviously improves the color saturation and lustrousness of a printed product and is beneficial to improving the anti-fake effect of the printed product.

Description

technical field [0001] The invention relates to a low-acid-value linking material composition, which is especially suitable for the preparation of engraving gravure printing inks that are not stained by water wiping, and belongs 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 forge banknotes by various means to disrupt the financial order. Therefore, effectively improving the public anti-counterfeiting features 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 adopted in the field of anti-counterfeiting printing, including the banknote printing industry. The engraving gravure printing is characterized by c...
