Abstract

The invention discloses universal environment-friendly composite printing ink and relates to the field of printing materials. The universal environment-friendly composite printing ink is prepared from, by weight, 30 parts of polyurethane resin, 10-15 parts of ternary resin, 0.5 part of electrostatic agent, 0.5-1 part of dispersing agent, 8-28 parts of pigment powder, 10-15 parts of acetic ether, 2-3 parts of isopropanol and 0.5-1 part of polishing and slipping agent matt powder. The invention further discloses a method for preparing the composite printing ink. The composite printing ink is reasonable in formula, the trouble of replacing ink for replacement of different printing base materials is saved, and printing efficiency is improved; meanwhile, a non-toxic solvent which does not contain benzophenone is used, pollution to the environment and harm to the health of workers are small, and printing solvent residues meet the relevant national requirements for food and drug packaging; meanwhile, the preparing method is simple and efficient, the qualified rate of products is high, operability is high, and the method is suitable for large-scale mechanical production.

Description

technical field [0001] The invention relates to the field of printing materials, in particular to a general-purpose environment-friendly composite ink and a preparation method of a general-purpose environment-friendly composite ink. 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...
