Problems solved by technology

[0003] Nowadays, the inks used in the conventional printing process generally use water-based polyurethane as the binder, but the printing ink prepared by this method has poor water resistance, poor printing effect, and easy to change color and blur when exposed to water, which brings great inconvenience to practical application.

Abstract

The invention discloses a packaging box green printing process based on water-based ink; the problems that ink selected in a conventional printing process generally adopts water-based polyurethane as a connecting material, but the printing ink prepared from the water-based polyurethane is poor in water resistance and easy to hydrolyze, and the printing effect is greatly influenced are solved; the water-based ink is firstly optimized and modified, a plant-based derivative is introduced into polyurethane, tung oil is eleostearic acid ester of glycerin and contains a conjugated double bond structure, the introduction of the structure can greatly improve the water resistance and chemical resistance of the water-based ink, the comprehensive performance of the water-based ink is improved, and the printing effect is more excellent. The process is reasonable in design and easy to operate, the surface of the packaging box obtained through printing is excellent in water resistance, the water-based ink is excellent in water resistance, abrasion resistance and chemical resistance, the surface printing effect of the packaging box is greatly guaranteed, and high practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a green printing process for packaging boxes based on water-based ink. Background technique [0002] Packaging printing is the printing of various packaging materials as the carrier, printing decorative patterns, patterns or text on the packaging, so as to make the product more attractive or more descriptive, so as to convey information and increase sales. Function; including printing of packaging cartons, packaging bottles, packaging cans, etc. Based on the requirements of environmental protection, it is necessary to use environmentally friendly materials and processes in the printing process. The printing process produces less pollution, saves resources and energy, and is easy to recycle and recycle printed materials after they are discarded. It can be naturally degraded and has little impact on the ecological environment. . [0003] Nowadays, the inks used in the convention...
