Problems solved by technology

[0002] Wall cloth is a very common material in the existing interior decoration. It is mainly set on the wall by glue and splicing. Although the quality of the existing wall cloth is relatively good, there are still shortcomings: easy to change color, not Resistance to scrubbing, moisture absorption and mildew, especially its poor waterproof effect
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

[0020] The present invention also provides a method for preparing the above-mentioned seamless composite waterproof wall covering, the preparation method comprising:

[0021] 1) Apply the adhesive to the surface of the non-woven fabric layer, and then perform preliminary drying;

[0022] 2) laying the short fibers on the surface of the adhesive, and then performing secondary drying to obtain the primary product;

[0023] 3) The initial product is compacted to make a seamless composite waterproof wall covering.

[0024] In step 1) of the above-mentioned preparation method, the specific conditions of preliminary drying can be selected within a wide range of conditions, but in order to make the prepared wall covering have a more excellent mechanical waterproof effect, preferably, in step 1), preliminary drying The drying at least satisfies the following conditions: the drying temperature is 50-70°C, and the drying time is 0.5-1h.

[0025] In step 2) of the above-mentioned prepa...

preparation example 1

[0029] 1) Stir styrene-acrylic emulsion, chlorinated ethylene-propylene-diene rubber, polysiloxane, polyacrylamide, sodium phosphate, mica powder and water for 1 hour to prepare mixture I;

[0030] 2) Sodium silicate, nano-calcium (average particle size is 20nm), and nano-diatomaceous earth (average particle size is 20nm) are added to the mixture I and stirred for 30min to prepare mixture II;

[0031] 3) Thickener (methyl cellulose) and defoamer (polyoxyethylene polyoxypropylene pentaerythritol ether) were added to the mixture II and stirred for 30 minutes to obtain adhesive A1; wherein, styrene-acrylic emulsion, The weight ratio of sodium silicate, chlorinated EPDM rubber, polysiloxane, polyacrylamide, nano-calcium, nano-diatomaceous earth, sodium phosphate, mica powder, water, thickener and defoamer is 100 :6:22:3:15:4:5:13:15:100:3:2.

Abstract

The invention discloses a seamless composite waterproof wall cloth and a preparation method thereof. The seamless composite waterproof wall cloth includes a non-woven fabric layer and a binding layerfrom top to bottom successively which are composited; staple fibers are implanted into a surface of the binding layer; the binding layer is formed by drying a binding agent; the binding agent consistsof styrene-acrylic emulsion, sodium silicate, chloride ethylene-propylene-diene monomer, polysiloxane, polyacrylamide, nano-calcium, nano-diatomaceous earth, phosphate sodium, mica powder, water, a thickener, and an antifoaming agent; the length of the staple fibers is 35-50 mm. The seamless composite waterproof wall cloth acquired from the preparation method possesses an excellent mechanical property and an excellent waterproof effect.
