Hereinafter, the manufacturing method of the decorative wallpaper of the present invention configured as described above will be described in detail.

1) Manufacturing Process of Pluster

70 ~ 80% by weight of acrylic copolymer, 18 ~ 22% by weight of titanium dioxide (TiO2), 0.05 ~ 0.09% by weight of dispersant, 0.2 ~ 0.3% by weight of antifoam, 0.75 ~ 0.83% by weight of freeze stabilizer, 0.03 ~ 0.07% by weight, thickener 0.4 ~ 0.45% by weight, and the stirrer is operated at high speed for 2 to 3 hours to sufficiently mix the ingredients added, then 3.0-4.0% by weight of water is added and the stirrer is restarted. To 3 hours or more to prepare a primary composition.

Preferably, the composition ratio of each component of the primary composition is 75% by weight of an acrylic copolymer (acrylic copolymer), 20% by weight of titanium dioxide (TiO2), 0.07% by weight of a dispersant, 0.25% by weight of an antifoaming agent, 0.79% by weight of a freeze stabilizer, 0.05 wt% preservative, 0.42 wt% thickener and 3.42 wt% water.

When the primary composition is prepared as described above, silica (silica, silica) having a specific color is added to the primary composition, and preferably, the ratio of the primary composition and silica is mixed in a ratio of 1: 2. (I.e., 200 g of silica is mixed when the primary composition is 100 g), and then the mixture into which the silica is added is mixed for 2 to 3 hours using a stirrer to prepare a secondary composition, and the secondary composition is a plus of the present invention. It forms a plaster.

On the other hand, by forming a base layer and a pattern layer to be described later using a pluster having the content as described above, while the pluster used in the wallpaper of the present invention has an elastic force enough to dry the wallpaper itself, the curved surface Not only can be easily constructed wallpaper of the present invention wall, but also has the advantage of easy distribution and storage.

However, if necessary to reduce the elasticity of the wallpaper of the present invention (that is, to keep the wallpaper somewhat rigid), the acrylic emulsion resin contained in the pluster is reduced to 50% by weight or less, There is a method using the method of supplementing the composition with water.

Alternatively, in general, the degree of solidification of the acrylic resin can be classified according to the TG (Temperature Glass), and if the TG is +20 ~ +30 has a tendency to solidify after drying, if the TG is +10 ~ -15 after drying The tendency to solidify is weakened and the elastic force becomes stronger. Therefore, if you want to reduce the elasticity of the wallpaper of the present invention, a TG of +10 ~ -15 may be used with reference to the TG value of the acrylic resin. In a preferred embodiment of the present invention, an acrylic resin having a TG value in the range of +5 to -5 is used.

As another method, the higher the mixing ratio of silica in the mixing ratio of the primary composition and the silica may reduce the elasticity of the wallpaper of the present invention, in which case the mixing ratio of the primary composition and silica as described above In addition to the method of mixing in a 1: 2 mixing ratio, this ratio can be mixed up to 1: 3 or 1: 4. (On the contrary, when the mixing ratio of the primary composition and the silica is 1: 1, the elasticity of the Pluster becomes stronger.)

2) Base layer formation process

First, a bottom layer made of any one of a glass fiber material, a cloth material, and a paper material is attached onto a release paper. In this case, preferably, the bottom layer is formed of glass fibers.

Next, after applying a sufficient amount of the pluster prepared in the pluster manufacturing process to have a thickness of 0.5 ~ 2.0 mm on the bottom layer surface, it is dried for 6 hours or more at a temperature of 20 to 25 degrees Celsius.

When the drying process is completed, the release paper attached to the bottom surface of the bottom layer is removed, and cut to meet a predetermined standard to form a base layer on the bottom layer.

3) glyph layer formation process

Masking a pattern paper with patterns such as animals, plants, and letters on the surface of the base layer formed through the process of forming the base layer as described above, and having a different color from the base layer on the projected pattern portion. After applying a sufficient amount of the pluster to have a thickness of 1.0 ~ 2.0, and dried for more than 8 hours at a temperature of 20 to 25 degrees Celsius to form a pattern layer on the base layer. In this case, when the pattern layer is formed, the patterned paper masked on the upper surface of the base layer is removed.

As described above, in the manufacturing process as described above, the pattern layer may apply a different color pluster, depending on the pattern it has.

In addition, in order to form a more colorful pattern, a separate sheet engraved with a separate pattern on the base layer or the pattern layer is additionally attached, or a known stone spraying material that gives a stone effect, or antique ( The decorative wallpaper of the present invention can be produced by applying a special paint known to express an antique effect or a shadow effect.

In addition, in the manufacture of the pluster forming the base layer and the pattern layer, the fine aggregate such as dolomite or marble stone may be additionally added to the base layer or the pattern layer so that the base layer or the pattern layer itself may exhibit the texture of the stone. .

In the above description, the decorative wallpaper of the present invention and its manufacturing method have been described in detail with reference to the accompanying drawings, but the present invention can be variously modified, changed, and replaced by those skilled in the art, and such modifications, changes, and substitutions are made by the present invention.
