Abstract

The invention relates to the technical field of printing ink, in particular to environment-friendly water-based ink, and solves the defects that most of organic solvents adopted in production of ink in the prior art contain toxic substances such as benzene, can emit strong smell in the manufacturing, transporting and using processes, are not environment-friendly and cause environmental pollution, and destroys human body healthy and environment. The water-based ink comprises the following components: a pigment, an acrylic acid synthetic emulsion, solid acrylic resin, an antifoaming agent, triethanolamine, a leveling agent, a dispersant, an anti-wear agent and water. The invention has the advantages of no chemical reaction, low production cost and high printing speed, the printed matter can replace offset print Heideburg, volatilizes water, is harmless to printing plant workers, is fireproof and safe in the production process, has favorable leveling property and uniformity of the paint, is the main direction for printing environment-friendly foods and medicine packages in future, and conforms to the development requirements of the Ministry of Environmental Protection for changing oil into water.

Description

technical field [0001] The invention relates to the technical field of printing inks, in particular to an environmentally friendly water-based ink. Background technique [0002] Ink is an important material for printing packaging materials. It expresses patterns and characters on the substrate through printing. The ink includes main components and auxiliary components. They are evenly mixed and rolled repeatedly to form a viscous colloidal fluid. Printing ink is a paste-like colloid formed by uniformly dispersing and mixing materials such as colorants, linking materials, additives, and solvents. [0003] Most of the organic solvents used in the production of traditional inks contain toxic substances such as benzene, which emit a strong odor during production, transportation and use, are not friendly to the environment, and have destructive effects on human health and the environment. [0004] Therefore, we propose an environmentally friendly water-based ink to solve the abo...
