  Hereinafter, the present invention will be described in detail with reference to embodiments.

(First embodiment)
(A) Kitchen panel material FIG. 1: is sectional drawing of the kitchen panel material 101 which concerns on the 1st Embodiment of this invention.

  As shown in FIG. 1, the kitchen panel material 101 according to the first embodiment includes a substrate 1 made of a noncombustible material mainly composed of an inorganic substance, a metal plate 2 formed on the substrate 1, and An organic resin layer 3 formed on the metal plate 2 and a protective layer 4 formed on the organic resin layer 3 are configured. The organic resin layer 3 can use an organic resin paint or an organic resin film. The protective layer 4 is preferably hard and has flame resistance. When the hardness and flame retardancy are not required, the protective layer 4 may be omitted. Although not shown, an adhesive may be applied to the interface between the metal plate 2 and the organic resin layer 3.

  Below, each component of the material 101 for kitchen panels is demonstrated in detail.

(substrate)
The substrate 1 is used to make the metal plate 2 difficult to be deformed mainly by an external force. The thickness of the substrate 1 is not particularly limited, but it is important to make the substrate 1 itself difficult to be deformed by an external force.

Non-combustible materials mainly composed of inorganic substances constituting the substrate 1 are gypsum board, calcium silicate board, cement slate board, magnesium oxide board, magnesium silicate board, rock wool molded board, aluminum hydroxide board, volcanic glassy composite. A laminate, ceramic paper, or a laminate of at least two of these can be used. The ceramic paper contains 95% or more of ceramic fibers (Al ₂ O ₃ : 40 to 60%, SiO ₂ : 60 to 40%), and also contains acrylic ester, acrylic resin, styrene resin and aluminum sulfate. Things can be applied. In particular, when an aluminum hydroxide plate is used, the weight of the entire material can be reduced. Further, by adding acrylic resin and pulp to the aluminum hydroxide plate, the weight can be further reduced and the entire material can be further reduced in weight. When two or more layers are laminated, a substrate is applied between the layers. Further, a ceramic fiber felt containing aluminum hydroxide as a main component and containing rock wool, a reinforcing agent, and a bonding agent can also be applied. For example, a ceramic fiber felt containing 65 to 75% aluminum hydroxide, 15 to 20% rock wool, and 5 to 10% reinforcing agent and bonding agent as components is desirable. Furthermore, a ceramic fiber board containing aluminum sulfate as a main component and added with wax and acrylic resin can also be applied.

(Metal plate)
(I) Material The metal plate 2 may be a known material such as a stainless steel plate, a surface-treated steel plate, an aluminum plate, or an aluminum alloy plate. As the stainless steel plate, a material specified in JIS G4305 can be used, and 18-8 stainless steel represented by SUS304 and chromium 18 stainless steel represented by SUS430 have good workability and are preferably used. As the aluminum plate or aluminum alloy plate, a material specified in JIS H4000 can be used.

  The surface-treated steel sheet includes zinc, a zinc alloy obtained by adding one or more kinds of zinc, nickel, iron, aluminum, magnesium and the like, a plated steel sheet plated with tin, chromium, copper, aluminum, aluminum alloy, nickel, or the like.

  As a plating method for the plated steel sheet, an electroplating method, a hot dipping method, a vapor deposition method or the like can be applied. After performing these platings, a known chemical conversion treatment may be performed. Known chemical conversion treatments include chromate treatment, phosphate treatment silane coupling agent treatment, Zr treatment and the like. When the surface-treated steel sheet is used, the memo paper or the cooking utensil can be easily fixed to the kitchen panel by the magnet.

  The thickness of the metal plate 2 of the kitchen panel material of the present invention is not particularly limited, but is preferably 0.5 mm or less from the viewpoint of reducing the weight of the material.

  However, it is preferable to use a thin metal plate having a thickness of 0.1 to 0.3 mm when the kitchen panel material of the present invention is cut with a hand-held circular saw for woodworking. If the thickness is less than 0.1 mm, several rolling steps are required, and the yield deteriorates, which is problematic in terms of manufacturing cost. Moreover, if the thickness of the metal plate is less than 0.1 mm, it is difficult to industrially laminate the organic resin film continuously on the coiled surface. On the other hand, if the thickness of the metal plate exceeds 0.3 mm, when a handy circular saw cutting means is used, cutting is difficult and the shape finish after cutting is not good.

(Ii) Method of Laminating Metal Plate to Substrate As described below, the metal plate 2 on which the organic resin layer 3 described in detail later is bonded to the surface of the metal plate 2 on which the organic resin layer 3 is not laminated. Then, the substrate 1 is laminated. It is preferable that the material of the substrate 1 and the material of the metal plate 2 are selected from the above-mentioned materials in such a combination that the laminate is not easily broken by an external force.

  First, an adhesive is applied to the surface of the substrate 1 or the metal plate 2 in advance to adhere the substrate 1 to the metal plate 2. After the substrate 1 and the metal plate 2 are bonded, heating or the like is performed to increase the adhesive force. In this case, the metal plate 2 is obtained by previously laminating the organic resin layer 3 on one side.

  The types of adhesives are urethane resin, silicone modified resin, urea resin, vinyl acetate emulsion, epoxy resin, melamine resin, phenol resin, olefin resin, acrylic emulsion, chloroprene, nitrile rubber, Known adhesives such as styrene-butadiene-rubber cyanoacrylate can be applied.

(Organic resin layer)
The organic resin layer 3 can be obtained by applying an organic resin paint on the metal plate 2 or by preparing an organic resin film in advance.

(I) Materials (a) Organic resin paints Organic resin paints are thermosetting or thermoplastic resin paints such as modified epoxies such as phenol / epoxy paints, urea / epoxy paints, amino / epoxy paints, and epoxy / ester paints. Paints such as vinyl chloride-vinyl acetate copolymer, partially saponified vinyl chloride-vinyl acetate copolymer, vinyl chloride-vinyl acetate-maleic anhydride copolymer, etc.-Vinyl paints such as epoxy-modified- Vinyl resin paint, epoxy amino modified-vinyl resin paint, epoxy phenol modified-modified vinyl resin paint such as vinyl resin paint, acrylic resin paint, oil paint, alkyd resin paint, polyester paint, styrene-butadiene copolymer, etc. Synthetic rubber-based paints can be used.

Corrosion resistance The coating amount, and 1 to 200 mg / dm ² in terms of economy, it is preferred that preferably is 10-100 mg / dm ^2.

(B) Organic resin film The material of the organic resin film is a polyester resin such as polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, ethylene terephthalate / ethylene isophthalate copolymer, butylene terephthalate / butylene isophthalate copolymer, or these. Polyesters such as blends of two or more polyester resins, polyethylene, polypropylene, ethylene / propylene copolymers, and those modified with maleic acid, ethylene / vinyl acetate copolymers, ethylene / acrylic acid copolymers, etc. Resin, polyamide resin such as 6-nylon, 6,6-nylon, 6,10-nylon, polycarbonate, polymethylpentene, and the above polyester resin and ionomer A rendered version is applicable.

  An organic resin film is comprised by the single layer produced using any 1 type among the above-mentioned materials, or is comprised by the multiple layer produced using two or more types of the above-mentioned resin materials. The thickness of the organic resin film is preferably 10 to 100 μm from the viewpoint of easy organic resin film laminating work, adhesive strength of the organic resin film, corrosion resistance, and economy.

  The organic resin film may contain a known pigment. For example, known inorganic pigments such as titanium oxide, zinc white, lead white, red rose, ultramarine, carbon black, graphite, or known organic pigments such as phthalocyanine, dioxazine, anthraquinone, quinacridone, watch ang red, dioxazine violet, etc. Applicable.

  The organic resin film is produced by heating and melting resin pellets composed of the above-described materials, extruding it from a T-die of an extruder, and forming the film into a desired thickness. In this case, the resin pellets may be heated and melted and directly extruded from the T die of the extruder onto the substrate 1, for example, the tin (Sn) plated steel sheet, and laminated.

(Ii) Method of Laminating Organic Resin Film on Metal Plate As the first method, as described above, resin pellets are heated and melted, and the resin pellets are directly applied to the substrate 1, for example, the Sn-plated steel plate, from the T die of the extruder. There is a method of extruding and laminating on the metal plate 2.

  As a second method, there is a method of forming on the metal plate 2 using a thermal bonding method. In the thermal bonding method, the organic resin film is brought into contact with the metal plate 2 heated to a temperature range to which the organic resin film adheres, and is sandwiched and pressed by a pair of rolls.

  When the organic resin film is thermally bonded to the tin-plated steel plate (metal plate) 2 using the thermal bonding method, it is necessary to pay attention to the following points. That is, unless the thermal bonding is performed at a temperature considerably lower than the melting point of tin, good adhesive strength between the organic resin film and the tin-plated steel sheet cannot be obtained. On the other hand, when the organic resin film is stretched in a uniaxial direction or a longitudinal and lateral biaxial direction, it is necessary to perform heat setting after the stretching process at a high temperature equal to or higher than the melting point of the resin. Therefore, it is important to appropriately select the resin to be used depending on whether or not the organic resin film is stretched.

  That is, when the organic resin film is stretched, it is necessary to use a resin having a melting point lower than that of tin. On the other hand, when the drawing process is not performed, it is not necessary to perform the heat setting after the drawing process, so that the heat bonding can be performed at a temperature considerably lower than the melting point of tin without considering the melting point of the resin.

  As a third method, there is a method of bonding the organic resin film 3 and the metal plate 2 using an adhesive. In this case, a known adhesive is applied and bonded to the interface between the organic resin film 3 and the metal plate 2 or the interface between the organic resin film 3 and the chemical conversion treatment layer of the metal plate 2. As the adhesive, for example, an emulsion type adhesive such as vinyl acetate resin, ethylene-vinyl acetate resin, urea resin, or urethane resin is preferably used. Both are safe against fire, have no odor, and are inexpensive.

(Protective layer)
(I) Material It is desirable that the protective layer 4 can impart excellent stain resistance, heat resistance, and wear resistance to the kitchen panel material. As such a material, a hard and flame-retardant acrylic resin, acrylic-modified silicon resin, fluororesin, or silica can be used. Silica can be a single film or a silica solidified with a binder such as an acrylic resin, an acrylic-modified silicone resin, or a fluororesin. The thickness is preferably 5 to 30 μm. If it is less than 5 μm, it is too thin, and the effect is not sufficient in terms of contamination resistance, heat resistance or wear resistance. On the other hand, if it exceeds 30 μm, the effect is saturated because it is too thick, which is not economical.

(Ii) Method for Laminating Protective Layer on Organic Resin Film The protective layer 4 is applied on the organic resin layer 3 of the metal plate 2 on which the organic resin layer 3 is laminated. The coating method is performed using a known method such as a roll coating method, a spin coating method, a spray coating method, or a curtain coating method. Then, the board | substrate 1 is laminated | stacked on the surface of the metal plate 2 of the side which has not apply | coated the protective layer 4 via an adhesive agent.

(B) Kitchen panel The above-mentioned kitchen panel material is cut in accordance with the standard dimensions in advance, or the kitchen panel material is transported to the work site, and the dimensions of the kitchen wall and other locations used on the site are used. It can be used as a kitchen panel by cutting according to the above.

  As described above, according to the kitchen panel material and the kitchen panel of the first embodiment of the present invention, since the metal plate 2 is formed on the substrate 1, the thickness of the metal plate 2 is reduced. In addition, the strength can be kept high, and even when a material that is easily broken, such as a plaster board, is used for the substrate 1, the metal plate 2 can be cut without causing a crack. Further, since the thickness of the metal plate 2 can be reduced, the weight can be reduced and the transportation becomes easy.

  Therefore, the kitchen panel material can be easily carried to the work site and can be easily cut at the site. In addition, individuals in ordinary households can purchase them at specialty stores in the suburbs, carry them easily to their homes, and process them easily according to the kitchen.

Further, as the substrate 1, a noncombustible material mainly composed of an inorganic substance, such as gypsum board, calcium silicate board, cement slate board, magnesium oxide board, magnesium silicate board, rock wool molding board, aluminum hydroxide board, volcanic glassy Since a multilayer board, ceramic paper, or a laminate of at least two of these is used, the fire resistance is excellent. The ceramic paper contains 95% or more of ceramic fibers (Al ₂ O ₃ : 40 to 60%, SiO ₂ : 60 to 40%), and also contains acrylic ester, acrylic resin, styrene resin and aluminum sulfate. Things can be applied. In particular, when an aluminum hydroxide plate is used, the weight of the entire kitchen panel material can be reduced, so that the material can be easily transported. When two or more layers are laminated, a substrate is applied between the layers.

  Moreover, the outstanding designability can be provided by including a pigment in the organic resin layer 3. Therefore, it is possible to create an environment suitable for the kitchen or preferred by the person working in the kitchen.

  Further, since the uppermost layer has a protective layer 4 composed of an acrylic resin, an acrylic-modified silicon resin, a fluororesin, silica, or a mixture of silica and at least one resin selected from these resins, the kitchen The stain resistance of the panel can be further improved, and heat resistance and wear resistance can be imparted to the kitchen panel. Therefore, the life of the kitchen panel itself can be kept long and the kitchen can always be kept clean. Even when the protective layer 4 is not provided, the organic resin layer 3 can provide excellent contamination resistance.

  In addition, by using a metal plate 2 containing a ferromagnetic material such as a surface-treated steel plate, a magnet or a clip with a magnet can be fixed to the kitchen panel, so the magnet panel can be attached to the kitchen panel or the clip. It is possible to fix a cooking recipe on the kitchen panel and cook while watching the recipe. Moreover, the cooking utensil can be fixed to the kitchen panel via a magnet or to the kitchen panel via a clip.

Nitrocellulose-alkyd resin-based inks are preferred from the viewpoints of heat adhesion.

(Method for producing printed layer on organic resin film)
The print layer 5 is formed as follows before the organic resin film 3 and the metal plate 2 are laminated.

  When the organic resin film is a single layer, it is provided on one side of the organic resin film 3 in advance. Then, the organic resin film 3 is laminated on the metal plate 2 so that the printed layer 5 is in contact with the metal plate 2. In this case, it is desirable to put an adhesive between the metal plate 2 and the printing layer 5.
