preparation example Construction
[0020] The present invention also provides a method for preparing the above-mentioned seamless silk embroidered wall covering, the preparation method comprising:
[0021] 1) Apply the adhesive to the surface of the cotton cloth layer, and then perform preliminary drying;
[0022] 2) laying the silk on the surface of the adhesive, and then performing secondary drying to obtain the primary product;
[0023] 3) The initial product is subjected to compaction treatment, and the surface of the silk layer is embroidered to prepare a seamless silk embroidery 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 anti-fungal effect, preferably, in step 1), The preliminary drying at least satisfies the following conditions: the drying temperature is 50-70°C, and the drying time is 0.5-1h....
preparation example 1
[0029] 1) Stir polyvinyl alcohol, urea, methyl methacrylate, polyacrylamide, alkylphenol polyoxyethylene ether, ethylene glycol and water for 1 h to prepare mixture I;
[0030] 2) Add starch, nano-silicon oxide (average particle size of 20nm), and nano-diatomaceous earth (average particle size of 20nm) to the mixture I and stir 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, polyvinyl alcohol, The weight ratio of starch, urea, methyl methacrylate, polyacrylamide, nano silicon oxide, nano diatomaceous earth, alkylphenol polyoxyethylene ether, ethylene glycol, water, thickener and defoamer is 100: 30:9:38:48:20:8:8:250:70:3:2.
preparation example 2
[0033] 1) Stir polyvinyl alcohol, urea, methyl methacrylate, polyacrylamide, alkylphenol polyoxyethylene ether, ethylene glycol and water for 1 h to prepare mixture I;
[0034] 2) Add starch, nano-silicon oxide (average particle size of 15nm), and nano-diatomaceous earth (average particle size of 15nm) to the mixture I and stir for 30min to prepare mixture II;
[0035] 3) Thickener (hydroxyethyl cellulose) and defoamer (polyoxyethylene polyoxypropanol amine ether) were added to the mixture II and stirred for 30 minutes to obtain adhesive A2; wherein, polyethylene The weight ratio of alcohol, starch, urea, methyl methacrylate, polyacrylamide, nano silicon oxide, nano diatomaceous earth, alkylphenol polyoxyethylene ether, ethylene glycol, water, thickener and defoamer is 100:25:8:35:45:15:5:7:200:50:2:1.
