Abstract

The invention discloses benzene-free ketone-free single-solvent printing ink and a preparation method thereof. The printing ink is prepared from the following components in parts by weight: 25-40 parts of polyurethane resin, 10-15 parts of ternary chlorine wax, 0.2-0.5 part of polyethylene wax powder, 0.5-1.0 part of dispersant, 0.5-1.0 part of anti-settling agent, 40-55 parts of mixed solvent, 0.5-0.8 part of dispersant, 0.5-1.0 part of adhesion promoter, 5-10 parts of defoamer and 25-40 parts of pigments. The preparation method of the printing ink comprising the above components comprises the following steps: weighing materials; pre-dispersing; grinding and dispersing; adjusting the viscosity and color; and filtering and packaging. The printing ink disclosed by the invention can be diluted by a single solvent during printing and is excellent in solubility and re-solubility and good in scraper adaptability. The preparation method is simple, the process conditions can be controlled easily and the product quality is stable.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a single-solvent ink without benzoketone and ketone and a preparation method thereof. Background technique [0002] Ink is an important material used for printing packaging materials. It expresses patterns and characters on the substrate through printing. The ink includes main components and auxiliary components, which are uniformly mixed and rolled repeatedly to form a viscous colloidal fluid. It consists of pigments, binders, additives and solvents. It is used for various printing of books, periodicals, packaging and decoration, architectural decoration, etc. For a long time, printing inks in the packaging industry have mostly been based on benzene-based solvent-based gravure plastic film inks, and benzene-based solvents will not only pollute the environment, but also cause harm to the human body. At present, many countries in the world have banned or restricted the use of benz...
