Wallpaper paving method

Abstract

The invention discloses a wallpaper paving method which comprises the following steps of S1, performing wall surface treatment, specifically, removing dust and stains on a wall surface, and polishingthe wall surface to be smooth; S2, using wallpaper adhesive for paving wallpaper, wherein the wallpaper adhesive is prepared from the following raw materials including, by mass, 40% to 50% of organicsilicon modified fluorine-containing acrylate emulsion, 4% to 5% of polyvinyl alcohol, 0.3% to 0.5% of a nano mildew preventive and the balance waterborne polyurethane emulsion, and the nano mildew preventive is formed by mixing nano silver / zinc-loaded copper hydroxyphosphate and nano barium metaborate according to the mass ratio of 1:(0.2-0.4); and S3, performing wallpaper surface treatment, specifically, evenly coating the outer surface of the wall surface with protective liquid according to the dosage of 30-50 g / m<2>, and performing natural curing to form a film. According to the wallpaperpaving method, the organic silicon modified fluorine-containing acrylate emulsion and the waterborne polyurethane emulsion are used for preparing the wallpaper adhesive, complementary advantages are formed in performance, and compared with a single waterborne polyurethane emulsion, the water resistance, the hydrophobicity, the aging resistance, the weather resistance and the wear resistance of thewallpaper adhesive are obviously improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a wallpaper paving method. Background technique [0002] Wallpaper, also known as wallpaper, is an interior decoration material used to paste walls, and is widely used in interior decoration of houses, offices, hotels, hotels, etc. When laying wallpaper, you need to use wallpaper glue to fix it. The adhesive used for wood fiber wallpaper or pure paper wallpaper is mainly made of natural starch or modified starch raw materials, and is equipped with methyl cellulose, vinyl acetate resin, etc., but starch and Cellulose wallpaper glue can be used as a nutrient for microorganisms, which is easy to degrade, has poor stability, and poor water resistance, especially when the wall is damp, the breeding microorganisms multiply rapidly, and it is very easy to cause mildew on the wall and delamination of the wallpaper. In addition, when the wall is damp for a long tim...

Problems solved by technology

When laying wallpaper, you need to use wallpaper glue to fix it. The adhesive used for wood fiber wallpaper or pure paper wallpaper is mainly made of natural starch or modified starch raw materials, and is equipped with methyl cellulose, vinyl acetate resin, etc., but starch and Cellulose wallpaper glue can be used as a nutrient for microorganisms, which is easy to degrade, has poor stability, and poor water resistance, especially when the wall is damp, the breeding microorganisms multiply rapidly, and it is very easy to cause mildew on the wall and delamination of the wallpaper. In addition, when the wall is damp for a long time, the wood fiber wallpaper or pure paper wallpaper will absorb water and swell, the fiber structure will become loose, and the microorganisms will further degrade and destroy the wallpaper, shortening the service life of the wallpaper

[0003] The existing patent uses adhesives such as water-based polyurethane and water-based resin to replace traditional starch-based and cellulose-based wallpaper adhesives. Although the problem of starch-based and cellulose-based wallpaper adhesives being self-generated and easy to mildew is overcome, water-based polyurethane and water-based resins contain a large amount of hydrophilic groups. It is easy to swell when it meets water, and its water resistance is poor. Water molecules can still penetrate into the wallpaper through the adhesive film, so it cannot be applied to the long-term damp wall environment
