It is thus possible to improve the design quality of a building.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a decorative ALC panel in which various patterns are formed on a panel surface of a lightweight cellular concrete (hereinafter referred to as ALC) panel, and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, an ALC panel is used as an outer wall of a building or the like. To improve the appearance, a pattern is cut on the surface of the ALC panel or a colored paint is applied to the surface. That is being done. But A
The method of cutting a pattern on the surface of an LC panel is troublesome, and the types of patterns are limited. Further, in a method of applying a paint, it is difficult to draw a complicated pattern or the like only by applying a single color or a plurality of colors, and thus the design is extremely limited. Furthermore, depending on the weather at the time of application,
There is also a problem that it takes a long time to dry the paint.

As another method, the surface of an ALC panel is
A method of thermally transferring a stone pattern such as marble, a landscape, or a complicated geometric pattern has also been proposed. Thermal transfer refers to the use of a thermal transfer sheet in which a desired pattern is printed with a paint on the base resin film surface of a synthetic resin sheet or high-quality paper, and the printed surface of the thermal transfer sheet is in contact with the panel surface, and This is a method in which the pattern of the thermal transfer sheet is thermally transferred onto the panel surface by rolling a roll heated to 100 to 200 ° C. with a roll transfer machine from above the film surface, and then the substrate film is peeled from the panel surface.

However, since the surface of the ALC panel has large and small cavities of open air bubbles and absorbs water, it is difficult to perform direct thermal transfer so that the pattern is not separated on the panel surface. Also, the pattern attached to the panel surface by thermal transfer,
The surface tends to be uneven along the unevenness of the panel surface, making it difficult to obtain a flat pattern surface. Therefore, prior to thermal transfer, the surface of the ALC panel needs to be subjected to a base treatment to smooth it or to impart water impermeability.

[0005] For example, Japanese Patent Publication No. 5-27593 describes a method in which a non-permeable layer is formed on the surface of an ALC product, and after smoothing this, a pattern is thermally transferred.
Japanese Patent Publication No. 7-113258 discloses that thermal transfer is performed on the surface of an ALC plate provided with a waterproof sealing material layer, and a protective layer of a weather-resistant plastic is formed thereon. Furthermore, Japanese Patent Publication No. 8-18398 discloses ALC
Form a primer layer and a water-impermeable coating layer on the panel surface,
A method of forming a pattern thereon by thermal transfer is disclosed.

[0006]

As described above, the conventional method using thermal transfer requires a base treatment to reduce unevenness on the surface of the ALC panel. In addition, since it is necessary to provide a roll transfer machine for thermal transfer, there is a disadvantage that equipment costs and construction costs increase. Furthermore, in order to uniformly heat the entire thermal transfer sheet with a heated roll, the size of the transfer sheet is limited to about 0.6 m in width × about 10 m in length. There is also a problem that it is necessary to combine a large number of transfer sheets, and the construction requires a lot of skill and many man-hours.

The present invention has been made in view of such a conventional situation,
A method in which a desired pattern can be directly applied to a panel surface of an ALC panel having pores or irregularities on its surface without using a base treatment by simple equipment and operation, and a cosmetic manufactured by the method. It is intended to provide an ALC panel.

[0008]

In order to achieve the above object, a method of manufacturing a decorative ALC panel provided by the present invention comprises:
At least a water-soluble release layer, a pattern layer, and an adhesive layer are formed on the mount, and the adhesive layer of the water transfer paper having the adhesive layer formed in this order is attached to the panel surface of the ALC panel, and a roller impregnated with water from the mount is used. The method is characterized in that after the pattern layer is water-transferred to the panel surface by rolling, the mount is peeled off from the panel surface.

In the method for producing a decorative ALC panel according to the present invention, at least one kind of ground treatment such as polishing, primer coating, or plaster coating is applied to the panel surface before the adhesive layer of the water transfer paper is attached. It can also be applied. Also,
After the pattern layer is water-transferred to the panel surface, a transparent protective film can be provided thereon.

[0010] Cosmetic AL produced by the method of the present invention.
The C panel is characterized in that the panel surface is provided with a pattern layer transferred by water. Further, the pattern layer transferred with water is fixed to the panel surface by an adhesive layer, and the thickness of the adhesive layer is preferably 0.02 to 0.1 mm.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Water transfer paper itself is used for painting on ceramics and the like, and its basic structure is already well known. Among such water transfer papers, the water transfer paper used in the present invention has, for example, at least a water-soluble release layer 3, a pattern layer 4, and an adhesive layer 5 formed on a backing sheet 2 in this order as shown in FIG. However, if necessary, other layers may be provided between the respective layers. Further, for convenience of transportation and storage, a release paper 6 is usually further adhered on the adhesive layer 5, and the release paper 6 is removed before use.

The substance constituting each layer of the water transfer paper 1 is as follows:
It may be a conventionally known one. For example, the backing paper 2 is water-absorbing and has high wet strength. As the water-soluble release layer 3, carboxymethyl cellulose, polyvinyl alcohol, gum arabic, a water-soluble resin, a water-soluble wax, or the like is used. Although a general printing ink or the like can be used for the pattern layer 4, it is preferable to use a weather-resistant ink in which a pigment is dispersed in a vehicle such as an acrylic resin. The release paper 6 is also known to have various release layers formed on the surface.

The adhesive layer 5 may be a rubber adhesive or an acrylic adhesive conventionally used for water transfer paper, various kinds of adhesive labels or sheets, etc., but irregularities due to bubbles appear. In order to securely adhere to the surface of the existing ALC panel, an acrylic-based rough surface adhesive, for example, a polyacrylate alkyl ester-based adhesive is preferable. If the thickness of the adhesive layer 5 is less than 0.02 mm, the stickiness is impaired and the pattern layer 4 cannot be securely adhered to the irregularities on the panel surface. Is too thick, and the sense of unity with the panel is impaired.
It is preferably in the range of 0.1 mm.

After removing the release paper 6, the water transfer paper 1
As shown in FIG. 2, the adhesive layer 5 adheres to the panel surface of the ALC panel 9. Next, the pattern layer 4 of the water transfer paper 1 is water-transferred and fixed on the panel surface by rolling the water transfer paper 1 from above the mount 2 with a roller 10 impregnated with water. Thereafter, by peeling the backing 2 from the panel surface, the pattern layer 4 fixed by the adhesive layer 5 remains on the panel surface, and a decorative ALC panel having a desired pattern is obtained.

According to the method of the present invention using the water transfer method, the pattern layer can be securely fixed to the panel surface of the ALC panel on which the irregularities due to the air bubbles have appeared without applying a base treatment. Moreover, the pattern layer is flat,
Almost no irregularities on the ALC panel, which is the base, appear on the surface. Furthermore, the pattern layer is firmly fixed to the panel surface, does not easily peel off, and can withstand long-term use.

In order to make the pattern transferred with water clearer, the panel surface of the ALC panel is polished in advance or smoothed by applying plaster or primer, or impermeable to water by applying synthetic resin or the like. , Etc., can be applied. Further, when there is a white portion in the pattern, it is preferable to apply a white paint on the panel surface in advance and then transfer it with water. Furthermore, in order to improve the durability of the pattern layer fixed to the panel surface, it is possible to form a protective film by applying a transparent and weather-resistant paint such as silicone resin or fluororesin on the pattern layer. It is.

In this manner, various patterns can be formed on the entire surface or a part of the ALC panel forming the wall surface of the building only by using the roller, so that it is simpler than the conventional method by spray painting or thermal transfer. It can be installed in a short time with equipment and operation, and it can be installed even at a building site because heating equipment is not required, and the design of the building can be improved. Further, the water transfer paper which does not require a heating roller can be applied to a wider area than the heat transfer paper, so that it is more excellent in workability and economic efficiency.

Moreover, it can be applied to an art panel having a groove formed parallel to the panel surface, a fore-edge surface or a chamfered portion of the panel, and can be applied to an existing old indoor or outdoor panel surface or an old transfer printing surface. It can respond to various needs such as construction. Furthermore, by appropriately selecting the type and thickness of the adhesive layer of the water transfer paper and the type and thickness of the ink of the pattern layer, the adhesion strength and durability of the pattern layer to the panel surface can be improved.

[0019]

An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a water transfer paper 1 used in this embodiment has a water-absorbent backing paper 2, a water-soluble release layer 3 made of a water-soluble wax, and a desired pattern made of ink having a thickness of 10 to 20 μm.
The pattern layer 4 electrostatically printed on m and the adhesive layer 5 are laminated in this order, and a release paper 6 is adhered to the surface of the adhesive layer 5. The adhesive used for the adhesive layer 5 is an adhesive composed of an aqueous acrylic acid emulsion that is slightly hydrophilic and does not react with the ink of the pattern layer 4, and the thickness of the adhesive layer 5 is about It is about 0.04 mm.

Using the water transfer paper 1, as shown in FIG. 2, a decorative ALC panel having a pattern layer 4 on the panel surface of an untreated ALC panel 9 was manufactured. That is, the adhesive layer 5 of the water transfer paper 1 from which the release paper 6 has been removed is adhered to the panel surface that has not been subjected to the base treatment, and then the surface of the backing paper 2 is coated with a hard sponge roller 10 impregnated with water. Was rolled while pressing. As a result, the pattern layer 4 is adhesively transferred to the panel surface by the adhesive layer 5, and the water-soluble release layer 3
Is separated from the pattern layer 4. Thereafter, the backing paper 2 was peeled off to obtain a decorative ALC panel 2 in which the pattern layer 4 was fixed to the panel surface by water transfer.

As shown in FIG. 3, the ALC panel 9
By applying a primer on the panel surface in advance and subjecting it to a base treatment, a primer layer 7 having a substantially flat surface is provided. Thereafter, the water transfer paper 1 is used to form a primer layer 7 in the same manner as described above. The pattern layer 4 was water-transferred. Further, a fluororesin was sprayed onto the pattern layer 4 obtained by peeling the backing paper 2 to form a protective film 8.

Each of the makeups A of FIGS. 2 and 3 thus obtained.
As for the LC panel, the adhesion test of the water-transferred pattern layer 4 was measured by a method based on JIS K 5400, 8.5, and as a result, none of the pattern layers 4 was peeled off. Further, as a result of measuring the durability for 2000 hours by a method based on JIS K 5400, 19.8, no crack or peeling occurred in any of the pattern layers 4. However, the decorative ALC panel of FIG. 3 provided with the primer layer 7 as a base and the protective film 8 as the uppermost layer showed less deterioration and a clear pattern layer 4 even after the test.

[0023]

According to the present invention, a desired pattern can be formed on a panel surface of an ALC panel having pits or irregularities by a simple method without performing a base treatment. Also,
Since no heating equipment is required, construction can be performed easily and in a short time not only at a factory but also at a construction site, and the design of the building can be easily improved. Further, since the water transfer paper is used, a large area can be constructed at a time as compared with the thermal transfer paper, and the unit price of the water transfer paper is low, so that the workability and the economic efficiency are further improved.

In addition, other than the ordinary ALC panel, an art panel in which grooves parallel to the surface are striped,
It can be applied to the small face and chamfered part of LC panel, and can be applied to the existing old ALC panel surface indoor and outdoor, and also to the old transfer printing surface. .
