[0002] Offset printing is the most important printing method at present. Its characteristic is that fountain solution is needed in the printing process, so offset printing ink is required to have good water resistance. In the past, the binder of offset printing ink was mainly vegetable oil such as linseed oil, but now most of them have been replaced by various resins with better performance. Common resins include rosin-modified phenolic resin, alkyd resin and polyurethane alkyd resin.

Although the ink composition provided in this patent document has the advantages of good transfer rate, high printing stability and obvious angular color effect of the printed pattern, its antibacterial performance is relatively poor and it is easy to breed bacteria, which affects its service life to a certain extent, and also affects its quality.

Wash the filter cake with anhydrous ethanol and deionized water for 3-5 times, respectively, and then vacuum dry it. The final product is a functional additive.

[0008] Furthermore, the preparation method of the pretreated inorganic carrier is: add a modifying liquid with a mass 5 to 10 times that of the inorganic carrier to a 0.01 to 0.03 g / mL inorganic carrier ethanol dispersion, and keep stirring the reaction at a temperature of 50 to 60°C for 2 to 4 hours; after the reaction is completed, centrifuge the resulting components, wash the filter cake with anhydrous ethanol for 3 to 5 times and then transfer it to a vacuum drying device, and finally vacuum dry it at a temperature of 50 to 60°C to obtain the pretreated inorganic carrier.

[0016] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, zirconium oxychloride, methyl cellulose and polystyrene microspheres are used as raw materials to prepare spherical nano zirconium dioxide with a porous structure, i.e., an inorganic substrate. Then, the inorganic substrate is put into ethanol, and a modified liquid containing 3-aminopropyltrimethoxysilane is added to the ethanol dispersion, and the 3-aminopropyltrimethoxysilane reacts chemically with the active groups on the surface of the inorganic carrier through heat preservation and stirring reaction, and finally a pretreated inorganic carrier is prepared. The obtained pretreated inorganic carrier is mixed with cyanuric chloride, N,N-diethylethylamine and a mixed solvent, and 2,6-dimethyl-2,6-octadienal is added, and finally 2,6-dimethyl-2,6-octadienal is successfully grafted on the surface of the pretreated inorganic substrate under the medium of 3-aminopropyltrimethoxysilane, and the introduction of 2,6-dimethyl-2,6-octadienal effectively enhances the antibacterial properties of the prepared solid powder.

[0017] The obtained solid powder is then mixed with 1,3-benzenediol, aluminum chloride and chlorobenzene, and the 1,3-benzenediol reacts chemically with cyanuric chloride bonded to the surface of the solid powder and its porous structure through heat preservation and stirring reaction. Finally, the two react chemically, and the generated reaction product is effectively encapsulated on the surface of the solid powder, and cooperates with 2,6-dimethyl-2,6-octadienal, and finally a dense three-dimensional antibacterial encapsulation layer is constructed on the surface of the solid micropowder and the inside of the porous structure to obtain a functional additive. The prepared functional additive can be used as a raw material for rotary red ink to significantly enhance its antibacterial properties. Furthermore, since the inorganic substrate is a nano zirconium dioxide with a porous spherical structure, its spherical structure can also enhance the wear resistance of the obtained red ink product to a certain extent, effectively ensuring its quality while also extending its service life.
