Environment-friendly printing ink and preparation method thereof

Abstract

The invention discloses environment-friendly printing ink and a preparation method thereof. The environment-friendly printing ink is prepared from the following formula components in parts by mass: 2 to 4 parts of polyurethane resin, 1 to 2 parts of lustering and smoothening agent matt powder, 1 to 3 parts of a preservative, 12 to 14 parts of three-component resin, 3 to 5 parts of cyrtomium rhizome, 3 to 5 parts of titanium dioxide, 4 to 6 parts of nano titanium dioxide, 3 to 5 parts of anti-freezing agent, 2 to 4 parts of ethyl acetate, 1 to 2 parts of an antistatic agent, 0.8 to 1 part of pigment powder, 11 to 13 parts of an air purifying slurry agent, 2 to 4 parts of a wetting agent and 4 to 6 parts of an electrostatic agent. The environment-friendly printing ink disclosed by the invention pollutes the environments little and damages body health of workers little; printing solvent residues meet related requirements of China on food and medicine packages; meanwhile, the preparation method disclosed by the invention is simple and efficient, the yield of products is high, and the operability is high, so that the preparation method is suitable for large-scale mechanized production.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an environmentally friendly ink and a preparation method thereof. Background technique [0002] In the printing and packaging industry, due to the small application area of ​​ink printing, suitable ink types should be selected for different printing substrates, and inks must be replaced when changing substrates. It leads to low efficiency of printing operations. The benzophenone solvent added in the ink volatilizes during printing, which will damage and pollute the body and environment of workshop workers. The standard printing operation environment temperature is 25°C, relative humidity is 65%, and it is dry in winter in the north Under the climatic conditions, the adaptability of the ink has decreased. [0003] The Chinese patent application number is CN 201510455344.6 which discloses a preparation method of quick-drying ink. The acrylic resin prepared by a specific process is used in ...
