Problems solved by technology

However, the traditional water-based foaming ink for wallpaper adopts the principle of physical foaming, and uses microsphere foaming agent to achieve the foaming effect, which has the problems of poor stain resistance and scratch resistance.
Products using chemical foaming agents can solve these problems. In the industry, chemical foaming inks using polyvinyl chloride paste as carriers have been printed on wallpapers, but due to the need to use a large amount of plasticizers and toxic solvents, the application is limited. limit

Abstract

The invention relates to water-based foaming ink special for wallpaper intaglio printing and a preparation method thereof. The water-based foaming ink comprises the following components in parts by weight: 30-40 percent of water-based film-forming emulsion, 40-50 percent of distilled water, 0.5-5 parts of wetting and flatting agent, 0.1-1 percent of antifoaming agent, 5-10 percent of pigment, 1-5 percent of foaming agent, 1-5 percent of dispersing agent and 1-5 percent of thickening agent. A machining process of the water-based foaming ink comprises the steps of: weighing raw materials in parts by weight, stirring the water-based film-forming emulsion in a stirring barrel, adding the pigment, the dispersing agent and the foaming agent in the water-based film-forming emulsion, and uniformly stirring; grinding a mixture in the stirring barrel at a high speed by using a grinding device; after the grinding is ended, adding the distilled water, the wetting and flatting agent, the antifoaming agent and the thickening agent in the stirring barrel, and uniformly stirring; finally filtering to obtain the water-based foaming ink. By adopting a water-based solvent, the water-based foaming ink is free of pollution to air, is capable of realizing a three-dimensional foaming effect after the water-based foaming ink is printed on common wallpaper, and is good in gas permeability; the surface of the wallpaper is scrubbing-resistant and extrusion-resistant without deforming.

Description

technical field [0001] The invention relates to a special water-based foaming ink for wallpaper gravure printing and a preparation method thereof. Background technique [0002] With the continuous development of the national economy and the improvement of people's living standards, and the emergence of a large number of commercial housing, hotels, and exhibition halls, people's requirements for interior decoration materials continue to increase. As an important part of modern interior decoration materials, foam wallpaper is becoming more and more popular. received people's attention. Because foam wallpaper has good decorative effect, convenient construction and environmental protection, it has been more and more widely used. From the initial use in hotels, office buildings, exhibition halls and other public places, it is now increasingly used in ordinary residential buildings. However, the traditional water-based foaming ink for wallpaper adopts the principle of physical f...
