Problems solved by technology

The second is that the printing viscosity of the ink required for ultra-high-speed printing is very low, and the proportion of solvent in the composite ink will be large. At the same time, most of the solvents evaporate at a certain speed. Since the length of the drying channel of the printing machine is constant, ultra-high-speed printing will inevitably lead to slower solvent evaporation than before. The residue will be more than the original, so it will lead to the problem that the solvent residue exceeds the standard and the ink is easy to stick back after the printing film is rolled.

Abstract

The invention discloses an environmentally-friendly polyurethane composite ink composition capable of adapting to ultra-high-speed printing. The composition comprises the following raw materials: 25-32 parts of amide modified polyurethane resin, 5-15 parts of a vinyl chloride-acetate copolymer liquid, 3-8 parts of a cellulose acetate propionate resin liquid, 8-33 parts of a pigment, 34-60 parts ofan environmentally-friendly mixed solvent, 1-2.5 parts of an auxiliary agent, 0.2-0.5 part of matt powder, and 0.2-1 part of wax powder. According to the invention, the environmentally-friendly polyurethane composite ink composition capable of adapting to ultra-high-speed printing has the advantages of good tinting strength, a vivid color and high transparency; the printing adaptability is strong, and the composition can be widely applied to printing of plastic flexible packaging composite materials such as PET, NY and BOPP; and in particular, the composition can be applied to ultra-high-speed printing with a printing speed higher than 350m / min, can effectively solve the problems that the composite strength of a printing film is not high, solvent residues easily exceed a standard, and a back adhesion phenomenon exists.

Description

Technical field [0001] The invention relates to the technical field of inks, in particular to an environmentally friendly polyurethane composite ink composition that can be adapted to ultra-high-speed printing and a manufacturing method thereof. Background technique [0002] With the development of my country’s social, economic and cultural undertakings, the printing, publishing and packaging industries have developed rapidly. In particular, the domestic demand for flexible packaging printing inks has increased dramatically. According to statistics, my country’s flexible packaging ink consumption has maintained a 25% growth rate year by year. This means that the amount of resin binder for ink is also increasing rapidly. As an important component of ink, resin binder determines the viscosity, viscosity, dryness, fluidity and other properties of ink to a large extent. Only high-quality ink with resin can make high-quality ink. At present, my country's gravure food packaging plasti...
