Abstract

The invention relates to environment-friendly water-based ink for PVC surface printing. The ink is prepared from, by mass, 30-40 parts of connecting materials, 30-40 parts of water, 10-20 parts of pigment and 5-10 parts of auxiliaries. The connecting materials are a modified polyurethane acrylic acid emulsion, the modified polyurethane acrylic acid emulsion is obtained by introducing the (1,4)-2-amino-2-deoxy-beta-D-glucan structure of deacetylation to branch chains of acrylic acid molecular chains. The environment-friendly water-based ink for PVC surface printing has the advantages of being good in environment-friendliness, high in adhesive force and simple in technology.

Description

technical field [0001] The invention relates to an environment-friendly water-based ink for PVC surface printing, which belongs to the technical field of water-based ink. Background technique [0002] Water-based ink has some characteristics different from other inks due to its own water solvent characteristics, and has the following advantages: [0003] 1. Green and environmental protection. Water-based ink does not use organic volatile solvents and contains almost no volatile organic compounds (VOC). This greatly improves the ink manufacturing and printing operation environment, and ensures the health of operators and end product users. [0004] 2. Printing characteristics. Water-based ink is relatively stable, and it is not easy to corrode the plate roller. The plate roller is easy to clean after printing, and it is suitable for most printing methods. [0005] 3. Security. Water-based ink does not contain organic solvents, the water-based system is relatively stable,...
