Embodiment 1

[0017] Step 1. Mix 25kg of white cement, 20kg of calcium carbonate, 15kg of aluminum hydroxide and 3kg of titanium dioxide evenly, then add 10kg of ethylene-vinyl acetate copolymer emulsion with a solid content of 56% and 27kg of water into the mixture, and stir evenly to obtain cement Base composite decorative materials;

[0018] Step 2. Apply the cement-based composite decorative material described in step 1 evenly on the upper and lower surfaces of the non-woven fabric. The coating thickness of the upper and lower surfaces is both 0.35mm. After coating, dry it in an oven at 80°C , to get polymer cement decorative wallpaper.

Embodiment 2

[0020] Step 1. Mix 30kg of white cement, 25kg of talcum powder, 20kg of magnesium hydroxide and 5kg of coating grade kaolin evenly, then add 15kg of polyacrylate emulsion with a solid content of 50% and 5kg of water to the mixture, and stir evenly to obtain cement-based Composite decorative materials;

[0021] Step 2. Apply the cement-based composite decorative material described in step 1 evenly on the upper and lower surfaces of the non-woven fabric. The coating thickness of the upper and lower surfaces is both 0.45mm. After coating, dry it in an oven at 90°C , to get polymer cement decorative wallpaper.

Embodiment 3

[0023] Step 1. Mix 26kg of white cement, 22kg of calcium carbonate, 16kg of aluminum hydroxide and 4kg of zinc oxide evenly, then add 12kg of polyvinyl acetate emulsion with a solid content of 30% and 20kg of water to the mixture, and stir evenly to obtain a cement-based composite decorative materials;

[0024] Step 2. Apply the cement-based composite decorative material described in step 1 evenly on the upper and lower surfaces of the non-woven fabric. The coating thickness of the upper and lower surfaces is both 0.25mm. After coating, dry it in an oven at 60°C , to get polymer cement decorative wallpaper.

Abstract

The invention discloses polymer cement decorative wallpaper. The polymer cement decorative paper is manufactured by drying a non-woven fabric which is uniformly coated with cement-based composite decorative materials on upper surface and lower surface; the cement-based composite decorative material is prepared by uniformly mixing the following materials in percentage by weight: 25%-30% of white cement, 10%-15% of polymer emulsion, 20%-25% of inorganic filler, 15%-20% of inorganic flame retardant, 3%-5% of inorganic opacifier, and 5%-27% of water. Besides, the invention further discloses a manufacturing method of the polymer cement decorative wallpaper. By adopting the inorganic material as the main body, the polymer cement decorative wallpaper disclosed by the invention has better flexibility, fireproof flame resistance, water resistance and better mildew-proof ability, can be well adhered with the cement wall body, and can be used as the decorative material of the building interior wall or the furniture by adding pigment, surface printing or pressing decorative patterns.

Description

technical field [0001] The invention belongs to the field of new building material science and engineering technology, and in particular relates to a polymer cement decorative wallpaper and a preparation method thereof. Background technique [0002] Wallpaper is a widely used indoor wall decoration material. It is favored by people for its various colors, rich patterns, luxurious style, safety and environmental protection, convenient construction, stability and durability, and easy repair and replacement. Common wallpapers are: PVC plastic wallpaper, pure paper wallpaper, non-woven wallpaper, wood fiber wallpaper, etc. However, the flame retardant problem of general wallpaper is very important for building fire safety. In addition, moldy wallpaper, wallpaper warping, etc. are also common problems with wallpaper. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a polymer cement decorative wallpaper aiming at the ...
