Problems solved by technology

[0002] Wallpaper is a very common material in existing interior decoration. It is mainly set on the wall by glue and splicing. Although the quality of the existing wallpaper is relatively good, there are still shortcomings: easy to change color, not resistant to scrubbing , easy to absorb moisture and mildew
Due to the above-mentioned defects, the promotion of decoration in decoration has been greatly limited, and it has brought great industry obstacles for the wallpaper industry.

preparation example Construction

[0012] The invention provides a method for preparing seamless hard wallpaper, comprising:

[0013] 1) mixing polyacrylic acid with a pigment, then printing on the surface of the base layer and drying to form a printing layer;

[0014] 2) mixing and foaming the hard resin, calcium carbonate, titanium dioxide, water, thickener and leveling agent, then transferring to the surface of the printing layer for curing and drying to form a process layer;

[0015] Wherein, the base layer is a non-woven fabric base layer, a cloth base layer or a paper base layer, and the hard resin is selected from polyacrylic acid and / or epoxy resin.

[0016] In step 1) of the present invention, the consumption of the raw material in the printing layer can be selected in a wide range, but in order to make the prepared wallpaper have more excellent anti-tarnish, scrub resistance, moisture-proof and anti-mildew properties; preferably Specifically, based on the total weight of the printing layer, the conte...

Embodiment 1

[0031] 1) Mix polyacrylic acid (weight-average molecular weight 1000) and pigments at a weight ratio of 92:8 at 25°C for 15 minutes, then print on the surface of the base layer (thickness 25 filaments, width 3m, non-woven fabric base layer) and Dry at 170°C for 1 min to form a printing layer (thickness is 3 filaments);

[0032] 2) Mix hard resin (weight average molecular weight 8000, polyacrylic acid), calcium carbonate, titanium dioxide, water, thickener (methyl cellulose) and leveling agent (silicone oil) according to 100:15:30:10: The weight ratio of 3:3 was mixed at 25°C for 0.8h, and foamed at 180°C for 0.8h, then transferred to the surface of the printing layer, cured at 130°C for 8min, and dried at 160°C for 8min to form a process layer (thickness: 35 silk) to make wallpaper A1.

Embodiment 2

[0034] 1) Mix polyacrylic acid (weight-average molecular weight 500) and pigments at a weight ratio of 90:10 at 15°C for 5 minutes, then print on the surface of the base layer (thickness: 20 filaments, width: 2m, cloth base layer) and place on Dry at 120°C for 0.5min to form a printing layer (thickness is 1 wire);

[0035] 2) Mix hard resin (weight average molecular weight 7000, epoxy resin), calcium carbonate, titanium dioxide, water, thickener (gelatin) and leveling agent (silicon urea-formaldehyde resin) according to 100:10:25:8: The weight ratio of 2.5:2.5 was mixed at 15°C for 0.5h, and foamed at 170°C for 0.5h, then transferred to the surface of the printing layer, cured at 120°C for 5min, and dried at 120°C for 5min to form a process layer (thickness: 25 silk) to make wallpaper A2.
