Problems solved by technology

[0003] The earliest water-based ink used was a natural resin shellac soluble in ethanol and alkaline aqueous solution as a binder. With the development of synthetic technology, rosin and maleic acid modified resins gradually replaced natural resins such as casein and shellac. Resin becomes the linking material of water-based ink. This type of modified resin greatly improves the printability of water-based ink, and its application is expanded to flexographic printing of kraft paper and corrugated paper. However, there are still gaps in gloss, water resistance and stability. There are many problems, and there is still a gap with solvent-based inks in terms of printability

Abstract

The invention relates to ink, in particular to water-based ink dedicated for the gravure surface printing of a plastic film, and the plastic film. The water-based ink dedicated for the gravure surface printing of the plastic film is prepared from the following raw materials: 30 parts of polycarbonate emulsion, 15-20 parts of pigment, 20-30 parts of propyl alcohol, 2-5 parts of accessory ingredient, 1-2 parts of wear-resistant agent, 2-3 parts of ammonia water and 30-50 parts of deionized water. The water-based ink has the beneficial effects that the water-based ink does not contain any volatile organic solvents, the working environment of operation personnel is improved, and fire hazard hidden dangers caused by static electricity and flammable solvents can be avoided. The water-based ink is neutral and has the advantages of good ink stability and good printing adaptation, and ink viscosity can be regulated by the deionized water in a use process, and operation difficulty is lowered.

Description

technical field [0001] The invention relates to an ink, in particular to a special water-based ink and a plastic film for gravure surface printing of plastic films. Background technique [0002] Water-based ink, referred to as water-based ink for short, is composed of water-soluble or water-dispersible polymer resin as a binder, organic pigments, solvent water and related additives. The main difference between water-based inks and oil-based inks is that solvent-based inks use organic solvents as solvents, while water-based inks use water as solvents. Therefore, water-based inks are more favored for their advantages such as extremely low VOC content, low toxicity and non-flammability. "Green printing" materials are developing rapidly in the flexible packaging and food packaging printing industries. Binder plays a vital role in water-based ink. It is the base material of ground toner in ink manufacturing, the main mobile phase and the film-forming substance after ink drying d...
