Embodiment 1

[0016] A method for producing wallpaper, comprising the steps of:

[0017] Step 1: Unwind the non-woven paper on the printing machine, and then send it to the coating machine;

[0018] Step 2: The coating machine uses the first PVC foam slurry to coat the surface of the non-woven paper with a PVC layer. The coating temperature is 170°C. After plasticizing, it is foamed and cooled at 210°C to obtain a foamed semi-finished product. ;

[0019] Step 3: Unwind the foamed semi-finished product and send it to the rotary screen printing device. The rotary screen printing device uses the second PVC foaming slurry to print the color and three-dimensional simulation pattern on the surface layer of the foamed semi-finished product, and pass through 170 ° C Hot air drying, and then cooling to get printed semi-finished products;

[0020] Step 4: Send the printed semi-finished product into the oven to heat up for correlative matching and foaming. The heating and foaming temperature is 200°...

Embodiment 2

[0026] A method for producing wallpaper, comprising the steps of:

[0027] Step 1: Unwind the non-woven paper on the printing machine, and then send it to the coating machine;

[0028] Step 2: The coating machine uses the first PVC foaming slurry to coat the surface of the non-woven paper with a PVC layer. The coating temperature is 180°C. After plasticizing, it is foamed and cooled at 220°C to obtain a foamed semi-finished product. ;

[0029] Step 3: Unwind the foamed semi-finished product and send it to the rotary screen printing device. The rotary screen printing device uses the second PVC foaming slurry to print the color and three-dimensional simulation pattern on the surface layer of the foamed semi-finished product, and pass through 175 ° C Hot air drying, and then cooling to get printed semi-finished products;

[0030] Step 4: Put the printed semi-finished product into the oven to heat up for correlative matching and foaming. The heating and foaming temperature is 17...

Abstract

The invention relates to a producing method of wallpaper. The producing method includes following steps: (1) unreeling non-woven paper on a printing machine and feeding the non-woven paper into a coating machine; (2) coating a surface of the non-woven paper with a PVC layer through a first PVC foaming slurry material by the coating machine, and performing plastification, foaming and cooling to obtain a foamed semi-product; (3) unreeling the foamed semi-product and feeding the foamed semi-product into a circular screen printing apparatus, printing color and stereo simulative patterns on a surface layer of the foamed semi-product through a second PVC foaming slurry material by the circular screen printing apparatus, drying the foamed semi-product in hot air and cooling the foamed semi-product to obtain a printed semi-product; (4) feeding the printed semi-product into a drying oven for performing temperature-increasing foaming; and (5) feeding a wallpaper semi-product into a cooling roller for cooling the wallpaper semi-product to room temperature with circulating water to obtain the wallpaper. Compared with a method in the prior art, the method is simple in production processes. The two different PVC foaming slurry materials are employed for coating, printing and relatively matched foaming. The wallpaper has a stereoscopic and simulative decorative effect.

Description

technical field [0001] The invention relates to the technical field of decorative materials, in particular to a production method of wallpaper. Background technique [0002] Wallpaper is one of the interior wall decoration materials widely used at present. It has rich and colorful colors, patterns and effects, is highly decorative, and is easy to use. It is deeply loved by people; The demand for modernization is becoming stronger and stronger, especially wallpapers with three-dimensional and simulated decorative effects. [0003] At present, PVC deep embossed wallpapers with a certain three-dimensional decorative effect have appeared on the market, but the degree of concave-convex contrast is limited, the overall is too thick, and there are many production processes, and the shortcomings of high requirements for equipment and plate rollers; The non-woven embossed wallpaper produced by the secondary foaming technology also has defects such as many production processes, diffi...
