Description

[Detailed Description of the Invention] The present invention relates to a wall covering plate that is attached to the interior of a building, such as the ceiling or side wall of a room, for the purpose of aesthetic appearance and prevention of dew condensation.

Conventionally, in buildings, when the outside temperature drops, dew condensation occurs on the indoor ceilings, side walls, etc., or condensation occurs in humid and steamy rooms, causing contamination and contamination of not only building objects but also furniture, furnishings, etc. This caused harmful effects such as corrosion.

However, the present invention is a new wall covering that solves the above-mentioned dew condensation phenomenon and also has an aesthetic effect, and is particularly characterized in that the structure that prevents dew condensation induces an aesthetic sense of the designed pattern. be.

The structure of the present invention will be explained in detail below based on the drawings of the embodiments.

That is, a base color surface 2 colored with a pigment or dye that easily dissolves in water is provided on the surface of a base plate 1 made of an organic or inorganic material such as wood, paper, metal, etc. A design pattern 3 of a single color or multiple colors that does not dissolve in water is formed so that the base color surface 2 is partially exposed, and the base color surface 2 is
A reversible moisture change layer 4 made of a water-based coating composition of a water-soluble or water-suspended binder having the function of absorbing and releasing moisture is provided thereon so as to cover the and design patterns 3.

Now, in the configuration of the present invention, the most important combination is the easily water-soluble base color surface 2, the water-insoluble design pattern 3, and the moisture reversible layer 4 that has the function of absorbing and releasing moisture.

Therefore, the surface of the base plate 1 made of organic or inorganic materials such as plywood, cardboard, cardboard, cloth, aluminum plate, thin steel plate, slate plate, calcium silicate plate, vinyl resin sheet, etc., is coated with a material that is easily soluble in water. A white or colored base color surface 2 is provided using pigments or dyes. The water-solubility of the base color surface 2 refers to the property that it oozes out and dissolves when it comes into contact with water or becomes wet with water in a dry state.

The color of the base color surface 2 harmonizes with the pattern and color of the design pattern 3 to be formed next to create a background color, and the exposed portion of the base color surface 2 actively participates in the pattern to create an aesthetic appearance. It is meant to strengthen.

The base color surface 2 may be formed by any known coating technique such as coating or printing.

Then, a design pattern 3 having a single color or a plurality of colors is formed on the base color surface 2 using pigments or dyes that do not dissolve in water so that the base color surface 2 partially forms a part of the pattern.

The water-insoluble nature of the design pattern 3 means that pigments and dyes do not ooze out or dissolve even if it comes into contact with water in a dry state or becomes wet with water.

The design pattern 3 may be formed by using known pattern forming techniques such as concave plate, convex plate, flat plate, and textile printing.

Next, the exposed part of the base color surface 2 and the design pattern 3
A reversible moisture change layer 4 having the function of absorbing and releasing moisture is formed over the entire surface of the base plate 1 so as to cover the substrate. Highly moisture-absorbing materials such as algae, moisture-absorbing fillers, extender pigments, and coloring pigments,
It consists of general materials necessary for preparing coating compositions and water-based binders such as water-soluble and water-suspended binders.
Supplied in paste form.

This paste-like coating composition is applied using a known coating technique such as a roll coater or curtain flow coater so as to cover the exposed portion of the base color surface 2 and the design pattern 3, and is dried to remove moisture. A reversibly changeable layer 4 is formed.

When a paste-like coating composition is applied, the design pattern 3 is water-based and the part of the base color surface 2 exposed between the water-insoluble design patterns 3 is easily water-soluble. Unaffected by moisture, base color surface 2
The exposed portion is dissolved by moisture and absorbed into the coating layer of the coating composition, that is, the moisture reversible layer 4, and is fixed as it dries.

Moreover, when a portion of the dissolved pigments and dyes on the exposed portion of the base color surface 2 are absorbed into the moisture reversible layer 4, they bleed, so that the exposed portion of the base color surface 2 delimited by the outline of the design pattern 3 becomes blurred. It penetrates deeply into the layer and colors it.

Therefore, the color sense becomes deeper and a beautiful pattern rich in elegance appears.

Furthermore, since the moisture reversible layer 4 has the function of absorbing and releasing moisture, if the wall covering version of the present invention is attached to the interior of a building, the ceiling and side walls can be exposed to temperature differences between the inside and outside. Even if dew condensation occurs due to humidity, the moisture is absorbed by the moisture reversible layer 4 and the condensation state is eliminated.

Moreover, the moisture absorbed by the moisture reversible layer 4 is released as the interior of the building dries, preparing for the next moisture absorption period, that is, the dew condensation period.

The color of the moisture reversible change layer 4 must be in harmony with the color of the design pattern 3 and the color of the exposed portion of the base color surface 2, and since it is necessary for the "color bleeding" of the exposed portion of the base color surface 2 to appear on the surface, generally a light color is appropriate, and dark colors that hide the color of the "color bleeding" are inappropriate.

As described above, the wall covering plate of the present invention has a beautiful decorative property with a sense of calmness and depth, as the design pattern and the blurring of the exposed portion of the base color surface form a blurred pattern, and it also has a dew condensation prevention effect. Therefore, it has many practical effects such as protecting not only architectural structures but also furniture and furnishings from moisture and moisture damage.
