Abstract

The invention relates to the technical field of wallpaper and provides white ink slurry which solves the defects of poor dispersion performance, weak covering capacity and low whiteness of the white ink slurry in the prior art. In addition, the invention also provides an application method of the white ink slurry in wallpaper. The white ink slurry is prepared from the following raw materials in parts by weight: 10-20 parts of styrene-acrylic emulsion, 0-10 parts of VAE emulsion, 20-25 parts of distilled water, 1-5 parts of a thickening agent, 3-8 parts of a dispersing agent, 0-1 part of a wetting agent, 1-3 parts of a defoaming agent, 1-2 parts of a retarder, 5-10 parts of propylene glycol, 30-50 parts of kaolin and 1-10 parts of titanium pigment.

Description

technical field [0001] The invention relates to a wallpaper, in particular to a white ink slurry and an application method thereof in the wallpaper. Background technique [0002] With the continuous development of the national economy and the improvement of people's living standards, people's requirements for interior decoration materials continue to increase. As an important part of modern interior decoration materials, wallpaper has been paid more and more attention by people. Wallpaper has various colors, rich patterns, luxurious style, safety and environmental protection, convenient construction, reasonable price and many other characteristics that cannot be compared with other interior decoration materials, so it has been widely popularized in developed countries and regions such as Europe, America, Southeast Asia and Japan. [0003] In the production process of wallpaper, white ink paste is often used, but the price of commercially available white ink paste is high, an...
