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 oily foam 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) Mix and foam the oily foaming resin, plasticizer, calcium carbonate, titanium dioxide, foaming agent, leveling agent, viscosity reducer and stabilizer, then transfer to the surface of the printing layer for curing and drying to forming 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 oily foaming resin is polyvinyl chloride.

[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 ...

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) Oily foaming resin (weight average molecular weight is 5000, polyvinyl chloride), plasticizer (dioctyl phthalate), foaming agent (1-benzoyl-2-p-toluenesulfonyl Hydrazine), leveling agent (silicone oil), viscosity reducer (D80 viscosity reducer) and stabilizer (methyl phosphite) according to the weight ratio of 100:100:10:25:12:0.8:1:0.7 in 25 Mix at 0.8°C for 0.8h, and foam at 180°C for 0.8h, then transfer to the surface of the printing layer and cure at 130°C for 8 minutes, and dry at 160°C for 8 minutes to form a process layer (thickness: 35 filaments) to produce 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) Oily foaming resin (weight average molecular weight is 4000, polyvinyl chloride), plasticizer (dibutyl phthalate), foaming agent (1-chlorobenzoyl-2-p-methylbenzenesulfonate) Hydrazide), leveling agent (urea-formaldehyde resin), viscosity reducer (type HD-60 viscosity reducer) and stabilizer (epoxy soybean oil) according to 100:90:9:20:10:0.5:0.8:0.5 The weight ratio is 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 filaments) to produce wallpaper A2.
