DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative plate having a metallic appearance.

[0002]

2. Description of the Related Art For interior and exterior of buildings, furniture, home electric appliances and the like, decorative boards are used which are made by applying various types of makeup to substrates made of various materials. Some decorative panels have a metallic appearance.These are roughly classified into ones that use a metal plate as a substrate to make use of the metallic feeling, and those that hide the substrate to give a metallic feeling by making up the surface. There are two things. As the former using a metal plate as a substrate, iron, stainless steel, aluminum, copper, brass or the like as a substrate,
There are crafts using gold, silver, tin, etc. as substrates. Utilizing the feeling of the metal of the material, the surface is changed by forming an oxide film, engraving, inlaying, pressing and the like. However, the color and gloss are determined depending on the material, and even if a change is given, the change is limited to a limited range.

[0003] The ones that give a metallic feeling by makeup include:
A substrate is formed by attaching a synthetic resin film or a metal foil having a metal thin film to various substrates, or is coated with a paint containing a pigment exhibiting metallic luster such as metal powder. Although it is suitable for mass production in terms of technique, the point that the color and gloss are determined by the metal material used is the same as the former, and it is monotonous and far from the real feeling. Therefore, a conventional decorative board having a metallic appearance has a strong metallic feeling and is not necessarily suitable for industrially obtaining an intended appearance having a specific hue or the like.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a metal-finished decorative board which can obtain a metallic appearance with an intended color or luster and is suitable for mass production. .

This is a colored layer containing a brilliant pigment. Preferably, by embedding and laminating the polishing pattern 11 on the lower surface of the transparent synthetic resin film so as to substantially smooth the unevenness, a superior metallic feeling is provided without involving the metal thin film layer. The above description referring to FIGS. 1 to 4 shows an example of the present invention, and some of the layers may be omitted or another layer may be added. Hereinafter, each part of the metal tone decorative board and the metal tone decorative sheet of the present invention will be described.

One characteristic feature of the decorative metal plate or the decorative metal sheet of the present invention is that a fine polishing pattern 1
1 is that the transparent synthetic resin film 10 having the metal pattern 1 has a metallic layer 20 that is laminated following the polishing pattern 11. As the layer 20 having a metallic feeling, a metal thin film layer having transparency, or having a large thickness and having no transparency, or a coloring layer containing a brilliant pigment (indicated by reference numerals 21 and 22 in FIG. 4). There is.

The transparent synthetic resin film 10 is made of a polyolefin resin such as a polyethylene resin, a polypropylene resin or a polymethylpentene resin, a polyethylene terephthalate resin, a polybutylene terephthalate resin, or a polyester such as a polyethylene naphthalate-isophthalate copolymer resin. Resin, polymethyl methacrylate resin, polyethyl methacrylate resin, acrylic resin such as polybutyl acrylate resin, polyamide resin represented by nylon 6 or nylon 66, polyvinyl chloride resin, polyvinylidene chloride resin, polyvinyl Alcohol resin, vinyl chloride-vinyl acetate copolymer resin, ethylene-vinyl acetate copolymer resin, ethylene-vinyl alcohol copolymer resin, cellulose triacetate resin, cellophane, polystyrene Resin, polycarbonate resin, a film of resin such as a polyarylate resin, or polyimide resin. Above all, a polyester resin film is suitable because it has mechanical strength, does not deteriorate in various properties even after a polishing step or a vapor deposition step, and has high transparency. From the viewpoint of improving mechanical strength, these films are preferably subjected to biaxial stretching, and at least uniaxial stretching in at least the winding direction (the longitudinal direction of the sheet). The transparent synthetic resin film may have a protective layer made of a transparent resin on the surface opposite to the surface having the following fine polishing pattern in order to protect the surface (not shown). . The resin constituting the protective layer may be thermoplastic, but is preferably a resin obtained by curing a thermosetting resin or a resin obtained by crosslinking and curing an ionizing radiation-curable resin in order to further enhance the protective function. In addition,
The thickness of the transparent synthetic resin film is 10
About 100 μm.

The fine abrasive pattern of the transparent synthetic resin film is typically a hairline pattern or a spin-processed pattern. The hairline pattern refers to a pattern in which very fine lines are formed during cold extrusion during the production of aluminum sashes and the like.However, in order to form a hairline pattern on a film, the brush roll or surface must be roughened. Using a rough roll, sandpaper, etc.
Normally, while the film is running continuously, these rolls and the like are rotated and brought into contact with each other to perform polishing, thereby forming fine grooves, thereby forming a straight hairline in which the wires are directly and long directly connected. By adjusting the thickness of the brush hair or metal wire of the brush roll, the surface roughness of the rough roll, and the degree of unevenness on the surface of the sandpaper,
The thickness of the line can be adjusted. Scratch hairlines with discontinuous lines in the middle, such as meandering each line by swinging the roll in a direction parallel to the rotation axis, or intermittently contacting multiple brushes with the film. Can also. The spinning pattern can be formed by moving a film on a film while rotating a brush, a blade, a grinding wheel, or the like. If the means for forming the hairline pattern and the means for forming each of the spin-processed patterns are used together, it is also possible to form a mixed pattern in which the respective patterns coexist. Alternatively, the hairline pattern or the spin-processed pattern formed as described above may be formed on the roller surface by etching, polishing, or the like, and pressed against the film.
As described above, even if it is not formed directly by polishing, a pattern formed by imitating a polishing pattern is referred to as a polishing pattern. In either case, the depth of the concave portion of the hairline pattern or the spin-processed pattern is about 3 μm on average, and the width is about 1 to 2 μm on average.

In the film prepared as described above, a metal thin film layer is formed on the surface on which the hairline pattern and the spinning pattern are formed, following the polishing pattern.
The formation of the metal thin film layer follows the fact that the average depth of the concave portion is about 3 μm, while the thickness of the metal thin film layer is about several hundred mm. Even if the metal thin film layer is formed on the formed surface, the concave portions are not filled and flattened, and the metal thin film layer is formed along the irregularities of the hairline pattern or the spin processing pattern. The metal thin film layer can be formed by plating, but a method suitable for mass production is a method of forming the metal thin film layer in a gas phase such as vapor deposition or sputtering. In addition, it is preferable to form a primer layer between the transparent synthetic resin film and the metal thin film layer in order to enhance the adhesiveness. As the primer layer, a known material such as a shira coupling agent, an alkyl titanate, or a polyamide resin can be used. In the metal decorative panel of the present invention, the thickness of the metal thin film layer is set to about 300 mm or more,
In the case where the metallic feeling due to the metallic thin film layer is shown exclusively,
When the angle is less than 00 °, the metal thin film layer having transparency may be shown in combination with the decoration of the lower layer. In the former, it is preferably between 400 ° and 500 ° and the light transmittance is about 1% or less. In the latter case of a transparent metal thin film layer, if the thickness is excessively thin, the metallic appearance is reduced, so that a thickness of 100 ° or more is required. Actually 200
When the angle is {250}, the light transmittance is preferably about 19% while maintaining the metallic appearance, which is preferable. Further, a primer layer may be formed on the exposed surface of the metal thin film layer 20 in order to enhance the adhesion between the metal thin film layer 20 and the next decorative layer. In the transparent synthetic resin film of the top layer used in the present invention, the hairline pattern and the spinning pattern are formed as described above, and the metal thin film layer is formed following the polishing pattern. In the case where a thin film layer is formed, only a monotonous appearance can be obtained, whereas a metal feeling similar to that obtained when cold extruding a metal can be obtained.

As the layer 20 having a metallic appearance, a colored layer containing a brilliant pigment (indicated by reference numerals 21 and 22 in FIG. 4).
May be used. Examples of the brilliant pigment include aluminum foil, powder, or flakes of an aluminum vapor-deposited film, if necessary, using a lubricant such as stearic acid or oleic acid, and the like, which are flaked by mechanical pulverization. Such a brilliant pigment and, if necessary, a coloring or coloring agent such as a pigment or dye for toning are added and dispersed or dissolved to form a synthetic resin paint having a fine abrasive pattern 11 on the transparent synthetic resin film 10. The layer 20 having a metallic feeling can be formed by applying the composition to the side surface. When the thickness is increased by performing the application twice, there is no pinhole and the metal feeling increases. Since the coating is colored, the thickness of the coating film becomes thicker than the formation of a metal thin film by vapor deposition or the like. Therefore, in general, the unevenness of the hairline pattern or the spin processing pattern is filled and smoothed. In addition, instead of a synthetic resin paint, a brilliant pigment is added to the adhesive for bonding to the lower layer, which is also made of a synthetic resin solution, and a coloring agent such as a pigment or dye for toning is added as necessary. And apply the dispersed or dissolved adhesive,
The layer 20 having a metallic appearance may be formed by bonding with a next layer, for example, a synthetic resin layer.

When the thickness of the upper metal thin film layer is small, the decorative layer 30 can be seen through the metal thin film layer, so that the decorative layer 30 has an appearance overlapping with the metallic feeling of the metal thin film layer. In general, if you apply a yellow transparent film to a metal glossy plate such as an aluminum plate, it looks like gold,
As is known, in the metal-finished decorative board of the present invention, the vertical relationship is reversed. However, even if yellow color is applied to the lower layer of the transparent metal thin film layer having a thickness of 300 mm or less, it still looks golden, and the metal thin film is above the decorative layer (= closer to the observer side). ), The metallic feeling is not easily impaired. In addition, copper color by light red coloring,
If it is light black, it can be made to look silver or the like. As the decorative layer 30, a pattern layer formed by printing an arbitrary pattern,
There are a weave pattern such as cloth, a marble-like film formed by extruding a different colored composition into a film, a colored layer containing a brilliant pigment, a normal colored layer, and the like. Examples of the brilliant pigment include those obtained by mechanically pulverizing aluminum foil, powder, or crushed pieces of an aluminum vapor-deposited film with a lubricant such as stearic acid or oleic acid, as needed. In any case, an appearance in which a metallic feeling is superimposed is exhibited, but as a pattern utilizing the metallic feeling, an abstract pattern is more suitable than a concrete pattern imitating a photograph or a real thing.
The hue of the decorative layer 30 can be freely determined. However, if the hue has the same color as that of the metal thin film layer, even if the transparent synthetic resin film on the surface of the metallic tone decorative board is damaged, the damage is hardly noticeable. Even in the case where the thickness of the metal thin film layer 20 is set to 400 to 500 ° or more and the lower layer cannot be seen through, it is preferable that the hue of the decorative layer 30 be the same color as the metal thin film layer in the same meaning.

When the decorative layer 30 is formed by printing or coating, the decorative layer 30 needs to be printed or coated. Except for the metallic layer 20, the decorative layer 30 is made of paper. And the use of plastic film. As the paper, thin paper, kraft paper, titanium paper, and resin-impregnated paper which has been impregnated with a resin in advance for the purpose of reinforcing between papers can be used. Other than these, a group of raw materials often used in the field of building materials, such as linter paper, paperboard, gypsum board raw paper, or vinyl wallpaper raw material provided with a vinyl chloride resin layer on the surface of paper, may be mentioned. Further, the following papers used in the office field, ordinary printing, packaging, and the like can also be used. That is,
Examples include coated paper, art paper, sulfuric acid paper, glassine paper, parchment paper, paraffin paper, and Japanese paper. Although distinguished from these papers, woven or nonwoven fabrics of various fibers having the following appearance and properties similar to paper can also be used. For example, inorganic fibers such as glass fibers, asbestos fibers, potassium titanate fibers, alumina fibers, silica fibers, or carbon fibers, or synthetic fibers such as polyester fibers or vinylon fibers. As the plastic film, those mentioned as the material of the transparent synthetic resin film 10 can be used in principle. Decorative layer 30 on paper or plastic film
Is formed, it is necessary to bond a transparent synthetic resin film having a polishing pattern and a metal thin film layer on the lower surface thereon. Although it depends on both materials to be bonded, it is preferable to bond by dry lamination performed by drying the solvent. In the case where paper or plastic film is colored, the paper or plastic film having a polished pattern and a metal thin film layer on the lower surface is not applied to the paper or the plastic without performing makeup by printing or coating. A plastic film can be attached. Even when the metal thin film layer is thick and has no transparency, forming a synthetic resin layer by backing it with a plastic film or applying a synthetic resin paint makes it easier to handle the sheet, and furthermore, the metal thin film layer Is coated, so that corrosion is also prevented. A decorative sheet having a structure in which a synthetic resin layer (or paper) is laminated on a lower surface of a transparent synthetic resin film having a polishing pattern and a metal thin film layer on the lower surface with or without a decorative layer on the lower surface is suitable for sticking to a substrate. Structure. Alternatively, instead of this laminated structure, a synthetic resin layer may be laminated on a substrate, and a transparent synthetic resin film having a polishing pattern and a thick metal thin film layer on the lower surface may be bonded. When a colored layer containing a glitter pigment (indicated by reference numerals 21 and 22 in FIG. 4) is used as the layer 20 having a metallic appearance,
On the lower surface of a transparent synthetic resin film having a polishing pattern and a coloring layer containing a glittering pigment laminated to follow the polishing pattern on the lower surface, if necessary, a synthetic resin layer and an adhesive layer are interposed in this order. To form a decorative metal plate laminated with a substrate, or a structure having only a synthetic resin layer interposed or a structure having nothing interposed therebetween. In these cases,
On the substrate side, an adhesive, an adhesive and a synthetic resin layer or only a synthetic resin layer are laminated thereon, and a polishing pattern and a coloring layer containing a glittering pigment which is laminated following the polishing pattern are laminated on the lower surface. It is good to laminate the transparent synthetic resin film having.

As the adhesive of the adhesive layer 40 for bonding both the substrate 50 and the decorative layer 30, a material selected according to each material is used. Among the adhesives that can be used, as a thermoplastic resin adhesive, polyvinyl acetate resin, polyvinyl alcohol, polyvinyl acetal (polyvinyl formal, polyvinyl butyral, etc.), cyanoacrylate, polyvinyl alkyl ether, polyvinyl chloride,
Examples include polyamide, polymethyl methacrylate, nitrocellulose, cellulose acetate, thermoplastic epoxy, polystyrene, ethylene-vinyl acetate copolymer, or ethylene-ethyl acrylate copolymer. Also,
Examples of the thermosetting resin adhesive include urea resin, melamine resin, phenol resin, resorcinol resin, furan resin, epoxy resin, unsaturated polyester resin, polyurethane resin, polyimide, polyamideimide, polybenzimidazole, and polybenzothiazole. There is something. Further, as a rubber (elastomer) -based adhesive, natural rubber, recycled rubber, styrene-butadiene rubber,
Examples include acrylonitrile-butadiene rubber, chloroprene rubber, butyl rubber, polysulfide rubber, silicone rubber, polyurethane rubber, stereo rubber (synthetic natural rubber), ethylene propylene rubber, and block copolymer rubber (SBS, SIS, SEBS, etc.).

As the substrate 50, a woody board such as a wood board, a plywood, a particle board, a medium density fiber board called MDF, a metal board such as aluminum, iron, stainless steel or copper, a gypsum board, a calcium silicate Ceramics, ceramics, glass, enamel, etc.
Fired tiles and the like are exemplified. In addition to these, composites of various materials such as a fiber reinforced plastic plate, a paper honeycomb having iron plates adhered to both sides, and a two-aluminum plate sandwiched with a polyethylene resin can be used as the substrate.

The substrate 50 also includes a metal plate as described in the previous paragraph. To use a metal plate as a substrate and give a metallic feeling from the outside, it does not feel strange, but the surface of decorative steel plate often used in places where strength is required is originally concealed by painting I have. Without painting, the surface of the iron will soon rust. Even with copper and other metals, an oxide film etc. is formed by the reaction with oxygen and other substances and gradually discolors, so it is difficult to change over a long period of time, to give a stable metallic feeling It is advantageous to give makeup. In addition, the exterior of home refrigerators and washing machines are often made by processing painted steel plates. In such cases, it is more convenient to use a production line that is easy to use with painted steel plates. It is. With the structure of the metal-finished veneer of the present invention, in the range of several tens of μm that is not different from the thickness of the painted portion of the coated steel plate, various appearances of the metal-finished veneer can be realized, without re-forming the press die or the like. There is an advantage that a conventional production line can be used as it is. If the steel plate is to be coated with another metal plate having a beautiful appearance, the thickness increases, so that the press mold needs to be remade or a separate means for pressing the metal plate for coating is required.

[0018]

(Example 1) A biaxially stretched polyethylene terephthalate resin film having a thickness of 20 μm was coated with a brush roll on one side, and the concave portion had an average depth of 3 μm and an average width of 1 to 2 μm in parallel with the film flow direction. After the hairline pattern was formed, a 1 μm thick polyvinyl acetate and polyethylene resin-based primer layer was formed on the hairline pattern side, and a thin film of aluminum was formed on the primer layer using a continuous vapor deposition machine to a thickness of 250 °. To a metal-like film, and a 1 μm thick layer of polyvinyl acetate and polyethylene resin on a thin film of aluminum.
m of primer layers were formed. Separately, a gray colored polyvinyl chloride resin sheet having a thickness of 100 μm was prepared and bonded to the primer layer side of the above-mentioned metal-like film by dry lamination using a polyurethane-based adhesive to obtain a metal-like decorative sheet. The obtained metal-finished sheet was adhered to the surface of a 0.5-mm-thick zinc-iron plate using a polyester resin-based adhesive to obtain a metal-finished sheet. The obtained metal tone decorative board, and the metal tone decorative sheet obtained in the middle are obtained by cold extrusion due to the addition of hair lines, compared to those using a film on which aluminum is simply deposited. The appearance was similar to that of stainless steel sheet, despite the fact that it was made of aluminum, due to the presence of the colored polyvinyl chloride resin sheet in the lower layer.

(Example 2) A film having a hairline pattern formed thereon was obtained in the same manner as in Example 1, and a primer layer was formed on the side on which the hairline pattern was formed. A paint containing an aluminum pigment was applied twice by gravure printing, and the same polyvinyl chloride resin sheet as used in Example 1 was adhered to the application surface side. I got a board. The result was very similar to a stainless steel plate.

Example 3 Example 1 was the same as Example 1 except that the thickness of the aluminum thin film was 100 to 200 °.
