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 boiling-water-resistant waterborne ink applied to PVC printing, which includes, by mass, 38-46 parts of an aqueous polyurethane-acrylic resin emulsion, 35-45 parts of deionized water, 5-8 parts of a styrene-acrylic emulsion, 7-17 parts of a pigment, 1-2 parts of ammonia water, 1-2 parts of a defoamer, 2-3 parts of an additive, and 2-5 parts of nano-fluorescent powder. The pigment is a modified pigment which is modified through the steps of: mixing a common pigment, potassium hexatitanate whiskers, glass flakes, titanium dioxide, barium sulfate and ethanol, adding the mixture to a container with a stirring unit, and stirring the mixture for 15-25 min; and then adding sodium m-carboxylbenzenesulfonate, and uniformly stirring the mixture to prepare a micro-emulsion; moving the micro-emulsion into a vacuum ball milling tank, and placing the ball milling tank in a ball mill to perform planetary vacuum ball milling; and relieving pressure, discharging the materials, and drying the materials to prepare the modified pigment. The boiling-water-resistant waterborne ink is high in color fastness to light, has high adhesion force, is low in viscosity and is good in water resistance.

Description

technical field [0001] The invention relates to a boiling-resistant water-based 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 s...
