AI Technical Summary

Problems solved by technology

However, the outdoor advertising inks currently used in the market have poor outdoor weather resistance, and generally cannot exceed one year, and serious yellowing and discoloration will occur, which greatly limits their application in high-end products; on the other hand, outdoor advertising The high temperature resistance of the ink needs to be strengthened, especially under long-term high-temperature baking, the ink is prone to fading, migration and falling off.

Abstract

The invention discloses water-based ink as well as a preparation method and application thereof. The water-based ink comprises the following components in parts by weight: 30-50 parts of water-based polyurethane acrylate; 2 to 10 parts of nano filler; 2 to 10 parts of a styrene-maleic anhydride copolymer; 12-18 parts of a pigment; 0.1 to 2 parts of a defoaming agent; and 20-60 parts of water. According to the water-based ink, the high-temperature resistance of the water-based ink is modified by adopting the water-based polyurethane acrylic resin and the nano filler, and the research shows that the high-temperature resistance and the weather resistance of the water-based ink can be jointly improved by the styrene-maleic anhydride copolymer and the nano filler. The water-based ink can be used for printing outdoor advertisements.

Description

technical field [0001] The invention belongs to the technical field of water-based ink, and in particular relates to a water-based ink and a preparation method and application thereof. Background technique [0002] Water-based ink has some characteristics different from other inks due to its own water solvent characteristics. It has the following advantages: 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; printing characteristics, water-based ink is relatively stable, it is not easy to corrode the plate roller, the plate roller is easy to clean after printing, and is suitable for most Printing method; safety, water-based ink does not contain organic solvents, the water-based system is relatively stable, and there will be no safety issues s...
