される化粧金属板の一つである。[Prior Art] Conventional vinyl chloride decorative metal plates are made by applying decorative printing to a vinyl chloride sheet in advance, and laminating another transparent vinyl chloride sheet as a protective layer on the printed side to form a composite sheet of vinyl chloride. Generally, this composite sheet is laminated onto a metal plate. After the metal plate laminated with the composite sheet is coiled at the end of the line, it is transported to the next process or to the customer. Such vinyl chloride decorative metal sheets have many advantages, such as being able to be colored, printed, and embossed in a variety of ways, and have excellent workability, mechanical strength, and moisture resistance, so they are the most commonly used decorative metal sheets. It is one of the metal plates.

もあった。[Problem to be solved by the invention] However, since the protective layer on the surface of such a vinyl chloride decorative metal plate is formed of a soft vinyl chloride sheet, the surface is soft and pressure marks are easily formed when handled. . Another problem is that the product is easily damaged when used. In terms of heat resistance, it was also weak due to the vinyl chloride resin. Further, the lower limit of the thickness of the vinyl chloride sheet is approximately 50 μm from the viewpoint of strength when processing it into a sheet shape. However, the thickness for good workability is larger than that, so in a composite sheet made by laminating two layers, the thickness of the vinyl chloride resin layer greatly exceeds 100 μm. Therefore, there was also the disadvantage that the cost was relatively high due to the thickness.

提供するにある。[0004] Therefore, we have considered forming the protective layer of the composite sheet into a thin film by coating it with a clear paint. In this case, the vinyl chloride sheet and printed layer forming the lower layer are susceptible to thermal deformation, so a clear paint that dries at room temperature was used for the surface protective layer. However, if the protective layer is made thick, the line speed will be slow and productivity will be poor if the protective layer is dried at room temperature. However, I learned that if I made the protective layer even thinner and dried it at room temperature, the line speed would increase, but it would be too thin to effectively exert its original protective function. The purpose of the present invention is to coat the surface side of a printed vinyl chloride sheet with a protective layer of heat-curing clear resin paint having sufficient hardness, and to coat the surface side of a printed vinyl chloride sheet with a protective layer of heat-curing clear resin paint, and to prevent the vinyl chloride sheet and the printed layer from being thermally deformed. The present invention provides a vinyl decorative metal plate and a method for manufacturing the same. Another object of the present invention is to provide a vinyl chloride decorative metal plate that can be mass-produced at low cost using a conventional production line, and a method for manufacturing the same.

好ましい。As the metal plate 10, a steel plate, a galvanized steel plate, another alloy plated steel plate, an aluminum plate, a stainless steel plate, etc. can be used. The vinyl chloride sheet 1 contains DOP of plasticizer based on 100 parts by weight of vinyl chloride resin.
A sheet material formed of a soft vinyl chloride resin containing 26 to 35 parts by weight of (dioctyl phthalate) and other stabilizers, heavy weight agents, pigments, etc. as necessary can be used. This is because if the blending ratio of DOP is less than 26 parts by weight, the vinyl chloride sheet 1 will be easily broken during molding of the decorative metal plate, and if it exceeds 35 parts by weight, it will be difficult to dry and bake the clear resin paint applied to the vinyl chloride sheet 1. This is because the plasticizer scatters violently and the vinyl chloride sheet 1 is susceptible to deterioration and discoloration. Although DUP (diundecyl phthalate) or the like can be used as a plasticizer, DOP is most preferred in order to prevent deterioration and discoloration due to heating during dry baking of the clear resin paint.

If it is less than m, the surface shape (smoothness) of the sheet itself during processing will deteriorate, resulting in poor printability, and if it exceeds 120 μm, the cost will increase, so 50 to 120 μm is preferable, and 70 to 90 μm is more preferable. . The ink used to form the printing layer 17 on the vinyl chloride sheet 1 can be vinyl chloride-based, urethane-based, acrylic-based, or polyester-based. Among them, the vinyl chloride type has good adhesion to the vinyl chloride sheet 1 after printing, and the printed layer 17 is difficult to peel off even if the vinyl chloride sheet 1 on which the printed layer 17 is formed before lamination is stored by coiling. Therefore, it is optimal.

Heat-curable clear resin paints include urethane-based, acrylic-based, polyester-based, fluorine-based, and alkyd-based paints. These resin coatings generally have higher hardness after curing than vinyl chloride sheets, and are also superior in heat resistance and stain resistance. For this resin paint, if a type such as a repellent type or a chijimi type containing silicone oil is used, it is possible to improve the matting effect and the design feeling. The thickness of the protective layer 20 formed by these is 5 to 60 μm

The vinyl chloride sheet 1 is laminated to a metal plate 10 and is not easily deformed by heat even when heated. Therefore, a type of clear resin paint that is heated and dried can be used. However, if the baking temperature exceeds 210°C, the vinyl chloride sheet 1 and the printed layer 17 begin to deteriorate and discolor, so it is desirable to heat and dry at a temperature lower than 210°C. Note that the thickness of the protective layer 20 of 5 to 10 μm is sufficient to provide a protective function. By forming such a thin film, material costs can be reduced and it can be easily formed by roll coating. metal plate 1
When the thickness of 0 is 0.3~1.0mm, the dry baking temperature is 160~210℃ and the line speed is 30m/min ~ 50m/min.

Because it has high printability, it can be printed with high decorativeness and design. The vinyl chloride sheet 1 is preferably used by laminating the printed layer 17 on it, but after laminating the vinyl chloride sheet 1 on the metal plate 10 on a line, the printing layer 17 is formed on the sheet 1. may be formed.

層が熱変形を受けることもよく防止できる。[Effects of the Invention] According to the vinyl chloride decorative metal sheet of the present invention, the protective layer 20 on the surface is made by baking and curing a hard thermosetting clear resin paint instead of the conventional vinyl chloride sheet. Therefore, the protective layer 20 can be made thinner than before, and material costs can be reduced. Moreover, as shown in Table 1 above, the product has a strength comparable to that of conventional products with respect to bending process, while the surface hardness of the protective layer 20 can be increased, which prevents pressure marks and scratches. It is possible to obtain a product that is difficult to cause and has excellent heat resistance. Further, according to the method of the present invention, after laminating the vinyl chloride sheet 1 on the metal plate 10, a heat-curable clear resin paint is baked onto the sheet 1 to form the protective layer 20. Therefore, even if the protective layer 20 is set to a desired thickness with just the right thickness, by increasing the baking temperature, the line speed can be increased and production can be carried out without any problems. It is also well possible to prevent the printed layer from undergoing thermal deformation.
