Problems solved by technology

[0008] 2. Adhesion problem
Especially when applied to plastic substrates, it is more prone to poor adhesion
[0009] 3. Surface effect problem
It still has defects such as poor adhesion, poor color fastness to light, slow drying, and high viscosity, which prevent it from being widely used

Abstract

The invention relates to a quick-drying water-based printing ink applied to PVC printing. The quick-drying water-based printing ink applied to PVC printing comprises a first component and a second component with the mass proportion of 1 to 2-5; the first component comprises the following components in parts by mass: 38 to 46 parts of a water-based polyurethane-acrylic acid resin emulsion, 35 to 45 parts of deionized water, 7 to 17 parts of first modified pigment, 1 to 2 parts of ammonia water, 1 to 2 parts of a defoaming agent and 2 to 3 parts of an aid; the second component comprises the following components in parts by mass: 35 to 45 parts of a water-based acrylic acid resin emulsion, 7 to 14 parts of second modified pigment, 2 to 4 parts of ammonia water, 1 to 2 parts of a defoaming agent and 4 to 7 parts of an aid. The quick-drying water-based printing ink applied to PVC printing, provided by the invention, has the characteristics of high quick-drying property, strong adhesive force and low cost.

Description

technical field [0001] The invention relates to a quick-drying water-based ink applied to PVC printing, and belongs to the technical field of water-based inks. 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, and there ...
