In the related art of interior decoration, most people use wall paper, and although the wall paper has abundant patterns, the wall paper needs to be adhered to a wall surface by using an adhesive material, and the raised edges are easy to occur when the wall paper is used for a long time. And a small number of people use the wall coating, so that the technical problem of edge warping can be effectively solved. The water-based pearl wall cloth is a wall coating, integrates the characteristics of wallpaper and emulsion paint, and enables the wall surface to generate various texture textures and artistic effects of light and shade transition.
The patent application publication No. CN110305548A discloses a preparation method of water-based artistic pearl wall cloth paint, which comprises the following steps: preparing materials according to the weight ratio, 30-40 parts of full-odor pure acrylic emulsion, 5-10 parts of diatomite, 1-2 parts of anion powder, 20-30 parts of pearl powder, 0.25-0.35 part of odor-free antifreezing dispersant, 0.18-0.22 part of odor-free wetting agent, 0.3-0.5 part of composite defoaming agent, 0.4-0.8 part of inorganic thickening agent, 0.08-0.12 part of odor-free ammonia pH regulator, 1.5-2 parts of high-boiling-point odor-free film forming agent, 0.3-0.5 part of odor-free environment-friendly composite type antiseptic and anti-algae agent and 25-35 parts of deionized water; step two: mixing an inorganic thickener and deionized water according to a ratio of 1:5 to generate inorganic thickener pre-dissolving pulp, mixing a odorless ammonia-free PH regulator and deionized water according to a ratio of 1:2 to generate odorless ammonia-free PH regulator pre-dissolving pulp, and mixing an odorless environment-friendly composite type anticorrosion algaecide and deionized water according to a ratio of 1:2 to generate odorless environment-friendly composite type anticorrosion algaecide pre-dissolving pulp; step three: adding the rest deionized water into a dispersing container, sequentially adding the odor-free antifreezing wetting agent, the odor-free antifreezing dispersant, the first composite antifoaming agent, the diatomite, the anion powder and the pearl powder under stirring, and stirring at a medium speed for 20-25 minutes at a temperature of not higher than 50 ℃; step four: sequentially adding a high-boiling-point odorless film forming agent, odorless ammonia-free pH regulator pre-dissolving pulp, full odorless acrylic emulsion and stirring at medium speed for 20-25 minutes at a temperature of not higher than 35 ℃; step five: and sequentially adding the inorganic thickener pre-dissolving slurry, the second composite defoaming agent and the odor-free environment-friendly composite type anti-corrosion and anti-algae agent pre-dissolving slurry under stirring, and stirring at a low speed until the mixture is uniform to obtain 100 parts of the waterborne artistic pearl wall cloth paint.
