Abstract

An alcohol-soluble lithographic ink comprises the following raw materials in parts by weight: 20-25 parts of pigment, 50-60 parts of bonding material, 25-30 parts of anhydrous ethanol, 1-2 parts of AEO4, 1-1.5 parts of tributyl phosphate, 1-3 parts of epoxy soybean oil, 1-2 parts of acrylic ester and 0.5-0.8 parts of polyethylene wax, wherein the bonding material comprises the following raw materials in parts by weight: 30-40 parts of polyvinyl butyral resin, 7-13 parts of rosin-modified phenolic resin, 3-7 parts of polytetrafluoroethylene wax, 13-27 parts of soybean oil, 3-7 parts of dry butyric acid, 30-35 parts of anhydrous ethanol and 20-25 parts of calcium carbonate. The alcohol-soluble lithographic ink not only can be degraded in an alcohol solvent, is environment-friendly and pollution-free, but also is strong in adhesion, high in abrasion resistance and high in gloss, and is applicable to large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of printing ink, in particular to a green and environment-friendly ink formula. Background technique [0002] With the continuous improvement of people's quality of life and living environment, people's requirements for energy-saving, low-consumption, non-toxic, non-polluting, and easily degradable products are getting higher and higher, and printing ink is one of the most polluting materials. Solvent-based printing inks contain a large number of toxic and harmful chemicals, including heavy metals, residual solvents, organic volatiles, and polycyclic aromatic hydrocarbons. These toxic and harmful substances can send chemical transfer, so that people are contaminated with toluene, xylene, lead, mercury, arsenic, chromium and other harmful substances in life, work and study. At present, environmentally friendly inks represented by water-based inks, alcohol-soluble inks, and UV inks are increasingly favored by...
