Problems solved by technology
[0004] In order to solve the metal pigments such as copper-gold powder (copper-zinc alloy) and aluminum-silver powder (aluminum powder) in environmentally friendly soybean oil offset printing metal inks, which will change color and become dark due to corrosion, and the pollution caused by petroleum solvents, the present invention uses alkylphenol Resin oil prepared from modified xylene formaldehyde resin is used as the main binder, which has water resistance, chemical resistance and electrical insulation, and has high gloss, does not corrode metal pigments, and has good compatibility with other resins; Long oil soybean oil / isophthalic acid alkyd resin is used as an auxiliary binder to improve the wettability of the binder to the metal pigment and the rheological properties of the ink; a layer of molecules is formed on the surface of the metal pigment with 1-aminooctadecane A layer of film to isolate the air from the metal pigment, thereby preventing the corrosion of the metal pigment by water and oxygen and carbon dioxide in the air, and protecting its shiny metallic luster

Embodiment Construction
[0012] In this example, the method of making the ink vehicle is:
[0013] (1), tung oil / soybean oil low molecular weight copolymer (A) preparation:
[0014] Put the refined tung oil and refined soybean oil into the reactor at a ratio of 25:75 by weight, protect it with an inert gas (or N2 or CO2 gas), heat up and stir, and polymerize at 250-260 ° C until the viscosity of the copolymer reaches 80 ~120mpa·s / 25℃, filter and discharge.
[0015] (2), the preparation of xylene formaldehyde resin:
[0016] Used xylene can be m-xylene or mixed xylene, and m-xylene reacts the fastest in mixed xylene, and the relative reaction speed ratio of m-position, ortho-position, p-position xylene and formaldehyde is 11:3:2 . Xylene and formaldehyde in the presence of sulfuric acid (or acetic acid, phosphoric acid, hydrochloric acid), the molar ratio of xylene and formaldehyde is 1: 1.2 ~ 1.8, through condensation reaction to generate xylene formaldehyde resin.

The invention relates to environmental protection type soybean oil offset printing metal printing ink. It uses china wood oil / soybean oil low molecular copolymer, alkyl phenol modification xylene formaldehyde resin, and long oil length bean oil / isophthalic acid alkyd resin as main film forming matter which forms printing ink connecting material with soybean oil, low arene high boiling point petroleum solvent, organic alumina gel, and metallic pigment preservative agent 1-amino group octadecane. The printing ink connecting material cooperates with the metallic pigment to make blue-gold, red-gold, blue-red-gold, and aluminium ink according to material constituent weight percentage.
Description
technical field [0001] The invention relates to a soybean oil offset printing metal ink applicable to offset printing ink binders in the field of IPC classifications C09D and C09F, in particular to an environment-friendly soybean oil offset printing metal ink. Background technique [0002] Compared with general color offset printing inks, offset printing metallic inks have a shiny metallic luster, and are mainly used for packaging and decoration printing. They play an inestimable role in beautifying packaging and increasing commodity value. But this type of ink contains 35-40% high-boiling petroleum solvent, which is equivalent to the head fraction of aviation kerosene and the tail fraction of light diesel oil. This petroleum solvent contains a lot of polycyclic aromatic hydrocarbons, which contain strong carcinogenic ingredients such as: 3,4-benzopyrene, 3-nitrobenzoketone, etc., which have a large amount of residue on printed matter and last for a long time , no matter it...
