Printing ink

Abstract

The invention discloses printing ink. The printing ink is prepared from the following raw materials in parts by weight: 10-15 parts of epoxy resin, 10-20 parts of polyurethane resin, 15-20 parts of polyamide resin, 10-15 parts of alcohol / waterborne acrylic resin, 5-10 parts of acrylic resin, 10-15 parts of black pigment or color pigment, 50-60 parts of solvent, 2-5 parts of viscosity modifier, 2-4 parts of dispersant, 2-3 parts of anti-settling agent, 0.5-1 part of antioxidant BHT, 1.5-2 parts of red dry oil, 0.5-1 part of paste dryer, 1-2 parts of magnet, 2-4 parts of hydrotalcite, 0.5-1 part of o-vanillin alanine schiff base, 1-1.5 parts of phenyl salicylate, 0.5-1 part of tribasic lead sulfate hydrate, 1-1.5 parts of polyoxy ethylene nonyl phenyl ether and 15-25 parts of deionized water. The printing ink disclosed by the invention is non-toxic and odorless and basically does no harm to a human body; further, is high in surface glossiness, and has good transparency and water resistance.

Description

technical field [0001] The invention belongs to the technical field of ink coatings, in particular to a printing ink. Background technique [0002] Ink is an important material for printing packaging materials. It is a viscous fluid substance with a certain color. It can express patterns and characters on the substrate through printing. At present, more than 95% of domestic plastic flexible packaging is printed by gravure printing. Way. Commonly used printing inks in China are generally made of chlorinated polymers. In the process of production and use, aromatic solvents such as strong solvent toluene need to be used to dissolve and adjust the viscosity of the ink. Therefore, when the solvent is not handled properly in the ink production process, it is easy to cause harm to the body of the ink production worker; the evaporation of the more toxic solvent contained in the printing process will also cause certain harm to the body of the printing worker; A certain amount of so...
