In this way, the decorative sheet 1 for a decorative dressing has a structure in which the sealer layer 3 / the base coat layer 4 / the pattern layer 5 / the surface protective layer 6 are sequentially laminated on the inorganic base material 2.
However, the sealer layer 3 is provided as necessary.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described.
The inorganic base material 2 in the present invention is particularly a ceramic siding material, specifically, a fiber-mixed perlite cement board or the like.
Further, the shape is plate-like, that is, the area of length and breadth is extremely large compared to the thickness. The general ceramic siding material has a thickness of 12 to 25 mm, a width of 455 to 1000 mm, and a length of 1800 mm to 3030 mm.
An inorganic base material 2 having a flat surface or an inorganic base material 2 having irregularities can be used, and a perforated inorganic base material 2 may also be used.
[0009]
Depending on the inorganic base material 2, the sealer layer 3 is provided on the inorganic base material 2 when the adhesion between the base coat layer and the inorganic base material 2 in which the coating material easily penetrates is insufficient. Further, after the sealer layer 3 is provided, a surface polishing treatment or the like is also performed.
As the paint, a two-component curable urethane resin paint or the like is used.
[0010]
The base coat layer 4 is usually a base color layer for the pattern layer 5 and is also used for the purpose of hiding the color of the inorganic base material 2.
The paint for providing the base coat layer 4 is appropriately selected in consideration of the adhesion to the inorganic base material 2 or the sealer layer 3 and the pattern layer 5.
Specifically, it is preferable to use a two-component-curing transparent or translucent acrylic urethane-based paint because both the properties of the paint and the adhesive can be used.
As a painting method, various coaters such as an air spray, an airless gun, a roll coater, and a flow coater can be used.
[0011]
As a method of providing the pattern layer 5 on the base coat layer 4, it is possible to directly print by gravure offset, screen printing, ink jet method, etc., or by printing by a transfer method.
The transfer method uses a transfer sheet in which a pattern layer 5 is provided on a release film by gravure printing, screen printing, offset printing, etc., and the pattern layer 5 is placed on the inorganic base material 2 (here, on the inorganic base material 2). It is transferred by heat onto the provided base coat layer 4).
The release film is a vinyl chloride resin, polypropylene resin, polyethylene resin, vinylon resin, or the like, and a sheet having a thickness of 10 μm to 100 μm is used.
The type, thickness, etc. of the resin of the release film are appropriately selected in consideration of the surface irregularity shape of the inorganic base material 2, the transfer temperature, and the like.
[0012]
The ink used for the pattern layer 5 is used, and the ink mainly includes a color material, a binder resin, an extender pigment, and an organic solvent.
As the color material, it is preferable to use a weather-resistant pigment.
Binder resins include vinyl chloride resin, urethane resin, polyvinyl butyral resin, acrylic resin, styrene resin, alkyd resin, polyamide, polyester, polyvinyl chloride, polyvinyl acetate, silicone resin, fluororesin, or these A copolymer or a mixture of a combination of resins is used.
[0013]
Since the pattern layer 5 formed by gravure printing and gravure offset printing is composed of an extremely thin layer of several μm, the color tone is affected by the base coat layer 4, and if the colors of the base coat layer 4 are different, the same pattern layer 5 can express a different design feeling.
[0014]
The surface protective layer 6 is preferably a urethane resin, urethane acrylate resin, silicone resin, fluororesin, or organic-inorganic composite polymer resin (metal alkoxide).
[0015]
In addition, you may add a ultraviolet absorber and a light stabilizer to the surface protective layer 6 as needed.
The thickness of the surface protective layer is preferably about 5 to 40 μm.
[0016]
As a construction method to make a decorative veneer using the decorative veneer 1 made of the present invention, a plurality of pillars made of wooden or steel, polymer resin are set up on the base of a normal concrete block wall, The decorative plate is fixed between the columns by nail fastening, screw fastening, metal fastening, or the like.
After completion of construction, make sure that the toilet bowl is not easily collapsed by earthquakes, winds, etc., according to the regulations of each prefecture, etc. Seal with caulking agent.
[0017]
【Example】
Hereinafter, the present invention will be described in detail by way of examples.
As the inorganic base material 2, a 15 mm thick fiber-mixed pearlite cement board (ceramics siding material) with a flat surface is coated with a urethane resin sealer to create a sealer layer 3, which is used as a base coat on the entire surface of the sealer layer 3. A base coat layer 4 was prepared by applying “V top base coat” manufactured by Dainippon Paint Co., Ltd. as a paint at 50 g / m ² (dry) and drying at 120 ° C. for 8 minutes.
[0018]
On the other hand, a transfer sheet was prepared as follows.
As the release film, a vinyl chloride film having a thickness of 80 μm and a plasticizer of 8 PHR (perts hundred resin) was used, and the pattern layer 5 was provided with gravure ink by gravure printing.
The main ingredients of this ink are phthalocyanine blue and iron oxide pigments (brown and ocher) as coloring materials (pigments), polyvinyl butyral resin (molecular weight 50,000, butyral substitution degree 65%), and extender barium sulfate. Other organic solvents are used.
[0019]
When the base coat layer 4 is dried and the surface temperature becomes around 60 ° C., the surface of the pattern layer 5 of the transfer sheet is linearly applied to the base coat layer 4 with a rubber roll heated to 160 ° C. with a rubber hardness of 40 °. The pattern film 5 was transferred to the base coat layer 4 by being closely adhered at 20 kg / cm 2 and a line speed of 20 m / min to peel off the release film.
[0020]
Next, 10 parts of an isocyanate-based curing agent was blended in an acrylic urethane resin-based transparent resin paint (V Seran # 100, manufactured by Dainippon Paint Co., Ltd.) and applied with a thickness of 10 μm (dry) with an air spray gun. A decorative sheet 1 for a decorative dress having a pattern layer 5 was prepared by heating and curing at 30 ° C. for 30 minutes.
[0021]
A plurality of iron pillars were erected on the base of a normal concrete block, and a decorative sheet 1 for the decorative dressing obtained between the pillars was screwed to create a decorative dressing.
Since it is the plate-shaped decorative sheet 1 for a decorative dressing, it was able to be constructed in a very short time. Moreover, since this decorative wrinkle was provided with a pattern layer, it was possible to obtain a wrinkle having excellent design properties.
Furthermore, a roof made of iron or aluminum was attached so that rainwater would not enter the top. Finally, it was sealed with a caulking material made of silicone resin at the joints of the dressing candy.
[0022]
【The invention's effect】
Since this invention is the above structure, there exist the following effects.
(1) It is a decorative board that can be made into a wrinkle having a pattern layer by printing against a wrinkled scissors, and has excellent design properties. For example, various ideas can be devised, such as making the pattern and color to match the appearance of the townscape.
(2) Since it is plate-like and has a better surface than a concrete block, an elaborate picture layer can be provided.
(3) Since it is plate-like and lighter than a concrete block, it is easy to construct, and can be constructed in a short time because it is nail-clamped and clamped.
In addition, it is effective to create a single-plate wrinkle that is difficult to understand if it is made up of top and bottom or four-way.
Therefore, the present invention exhibits an excellent practical effect as a decorative plate for uses such as a cosmetic candy.
