Problems solved by technology

However, there are still many deficiencies in the ink slurry in the raw materials for wallpaper production: 1) the slurry is opaque and will cover the pattern below, which limits the rendering effect of the wallpaper pattern and the three-dimensional aesthetic feeling of the wallpaper pattern; The surface coating has poor wear resistance and is easy to wear, which leads to defects in later construction and use, which affects the promotion of the wallpaper industry; 3) In the traditional wallpaper production process, a gold spraying process will be added in the post-production process of the wallpaper (in the wallpaper production process). Sprinkle gold powder, silver powder, etc. on the surface for decoration), there is a phenomenon that the gold powder is easy to fall off, which seriously affects the appearance of the wallpaper. It reacts with other microorganisms, causing the metal powder to change color, which seriously affects consumers' pursuit of wallpaper color and environmental performance, and is not conducive to the healthy development of the wallpaper industry.

preparation example Construction

[0058] The present invention also provides a method for preparing the above-mentioned transparent slurry, comprising the following steps:

[0059] a) uniformly mixing silicone-modified acrylic resin, alkyd resin, dispersant, leveling agent and solvent to obtain a mixed solution;

[0060] b) Add anhydrous transparent powder and a drying speed modifier to the mixed solution under stirring condition, and after mixing evenly, use a solvent to adjust to the required viscosity to obtain a transparent slurry.

[0061] The components and proportions of the raw materials are the same as above, and will not be repeated here.

[0062] In step a), the uniform mixing is preferably carried out at room temperature.

[0063] In step b), the uniform mixing is preferably carried out at room temperature.

[0064] The transparent slurry layer prepared by the transparent slurry provided by the present invention has better transparency, stronger adhesion, and better wear resistance, and can be we...

Abstract

The invention provides a transparent paste, a wallpaper and a preparation method thereof. The transparent paste comprises, in parts by weight: 40-60 parts of organosilicon modified acrylic resin; 20-40 parts of alkyd resin; anhydrous transparent 40-80 parts of powder; 1-8 parts of dispersant; 1-5 parts of leveling agent; 1-3 parts of drying speed regulator; 60-100 parts of solvent; 1-10 parts of auxiliary agent. The transparent slurry layer prepared from the transparent slurry provided by the present invention can be well matched with other layer groups, and the prepared wallpaper can present multi-layer effect and three-dimensional effect, and the overall appearance is beautiful. At the same time, the wet tensile strength of the wallpaper is relatively large. , Better scratch resistance and longer service life.

Description

technical field [0001] The invention relates to the technical field of interior decoration materials, in particular to a transparent slurry, wallpaper and a preparation method thereof. Background technique [0002] Wallpaper, which refers to paper or cloth as the base material, with polyvinyl chloride resin or other fiber materials as the surface layer, which is made by calendering or coating, printing, embossing or foaming. indoor wall decoration materials. It has the characteristics of rich colors, various patterns, different textures, noble and elegant decorative effects, and high construction efficiency. It is widely used in home and engineering decoration. [0003] As people's aesthetic requirements for wallpaper are increasing day by day, the three-dimensional patterns presented on the surface of the wallpaper are becoming more and more abundant. However, there are still many deficiencies in the ink slurry in the raw materials for wallpaper production: 1) the slurry ...
