Problems solved by technology

For another example, what patent CN100526554C discloses is the method for preparing PVC humidity-adjusting wallpaper, and PVC wallpaper does not have environmental protection and flame retardancy, so it needs to be improved
In addition, these two patents only rely on the water absorption and discharge function of inorganic fillers to achieve the purpose of humidity control, but the water absorption and discharge capabilities of inorganic fillers are limited.
Therefore, the existing wallpaper with humidity control function cannot meet the purpose of quickly and efficiently adjusting indoor humidity.

Embodiment 1

[0031] First prepare 15 parts of carboxymethyl cellulose aqueous solution (solid content is 1%), and grind it into 200 mesh particles, then use mechanical stirring to disperse 20 parts of sepiolite and 1.5 parts of hyperbranched polycarboxylic acid dispersant in 30 After stirring for 12 minutes, add 15 parts of an aqueous solution of carboxymethylcellulose and continue stirring for 7 minutes. Then add 30 parts of water-based polyurethane, 1.5 parts of mercaptans and 0.5 part of higher alcohol, and continue to stir for 18 minutes; then add 1.5 parts of polyurethane thickener to adjust the viscosity of the slurry.

[0032] The moisture-adjustable functional paste was printed on a non-woven paper substrate with a thickness of 300 μm by a gravure printing process, with a drying temperature of 120 °C and a drying time of 11 minutes.

Embodiment 2

[0034] First prepare 22 parts of polyacrylate aqueous solution (solid content is 1%), and grind into 150 mesh particles, then use mechanical stirring to disperse 25 parts of montmorillonite, 20 parts of zeolite and 0.8 part of polyacid copolymer dispersant in 20 parts of water, after stirring for 8 minutes, add 10 parts of polyacrylate aqueous solution, and continue stirring for 5 minutes. Then add 22 parts of polyacrylate copolymer emulsion, 1.2 parts of soybean lecithin and 0.5 parts of polysiloxane, and continue to stir for 10 minutes; then add 0.5 parts of polyurethane thickener to adjust the viscosity of the slurry.

[0035] The moisture-adjustable functional paste was printed on a 500-micron thick stone paper substrate by a rotary screen printing process, with a drying temperature of 90 °C and a drying time of 10 minutes.

Embodiment 3

[0037] First prepare 30 parts of hydroxyethyl cellulose aqueous solution (1% solid content), and grind it into 120 mesh particles, then disperse 5 parts of zeolite and 0.5 parts of polyacid copolymer dispersant in 20 parts of water by mechanical stirring After stirring for 19 minutes, add 30 parts of an aqueous solution of hydroxyethyl cellulose, and continue stirring for 12 minutes. Then add 42 parts of polyacrylate copolymer emulsion, 1.2 parts of soybean lecithin and 0.5 parts of polysiloxane, and continue to stir for 10 minutes; then add 0.5 parts of polyurethane thickener to adjust the viscosity of the slurry.

[0038] The moisture-adjustable functional paste was printed on a 100 μm thick stone paper substrate by a flat screen printing process, with a drying temperature of 90 °C and a drying time of 15 min.

Abstract

The invention relates to environment-friendly humidifying wallpaper and a preparation method thereof. The wallpaper comprises a wallpaper base layer, wherein a waterborne printing coating with a humidifying function is printed on the wallpaper base layer; the wallpaper base layer is environment-friendly rich mineral paper or non-woven paper; the waterborne printing coating consists of an adhesive, a porous inorganic mineral material, super absorbent resin, water, a thickening agent, an antifoaming agent and a wetting agent, and the absorbent resin has an effect of increasing the water absorption capacity of the wallpaper. The waterborne printing coating is printed to the wallpaper base layer by adopting a round screen or plain net or gravure process. The thickness of the wallpaper base layer is 100-1,000microns, and the thickness of the waterborne printing coating is 5-50 microns. When the wallpaper achieves a decorative effect, high-efficiency indoor humidity regulation can be performed, and the environment-friendly humidifying wallpaper is pollution-free and formaldehyde-free and has no indoor volatile organic pollutant.

Description

technical field [0001] The invention belongs to the field of decorative materials, in particular to a humidity-adjusting environmental protection wallpaper and a preparation method thereof. Background technique [0002] Humidity is closely related to human life. Studies have shown that when the indoor humidity is lower than 40%, human skin is wrinkled, the resistance of the respiratory system is reduced, bacteria and viruses will take advantage of it, furniture will be deformed and burst, coatings, mural powders, etc. When the humidity is higher than 60%, the environment is too humid, the reproduction of microorganisms is accelerated, and the items are prone to mildew, rot or rust. Therefore, adjusting indoor humidity has become a top priority. Porous mineral materials (such as diatomaceous earth, zeolite, sepiolite) are natural non-toxic materials, and have a large number of pores, which have the function of water absorption and water release, so these porous mineral mater...
