More specifically, the present invention relates to metal plates used particularly for exterior wall materials, roofing materials, and the like.

彩の金属板にできない不利があった。However, most of these types of metal plates generally have a coating film formed on the decorative surface using polyethylene resin paint, alkyd resin paint, epoxy resin paint, etc., but these are usually exposed to ultraviolet rays and over time. Discoloration, deterioration of the paint film, cracking, and peeling occurred, accompanied by the occurrence of rust. For this reason, metal plates using fluororesin paints with good weather resistance are also on the market. however,
Fluororesin paints are expensive, and in order to eliminate color unevenness on metal plates using this paint, a coating film with the same thickness as a regular colored steel plate is formed, and the added value is low compared to the added value. It also had the disadvantage of being expensive. Furthermore, fluororesin paints
There were restrictions on the pigments (coloring agents) that could be used for this, and there was a disadvantage that metal plates could not be made in any color.

含めて被覆できるため好ましいものである。The metal plate according to the present invention will be explained in detail below using the drawings. FIG. 1 is an enlarged cross-sectional view of the metal plate A, where 1 is a color steel plate and 2 is a fluororesin coating layer. That is, the color steel sheet 1 is a galvanized steel sheet such as a hot-dip galvanized steel sheet, an alloyed hot-dip galvanized steel sheet, an electrolytic galvanized steel sheet, a hot-dip zinc/aluminum 1, an alloy-plated steel sheet, an aluminum-plated steel sheet, a lead or tin alloy-plated steel sheet, or a tin-plated steel sheet. The base plate is plated steel plate, electrolytic chromic acid treated steel plate, stainless steel plate, aluminum alloy plate, zinc alloy plate, titanium plate, etc., and primer treatment is applied to both sides, and at least one coat is applied to the decorative surface.
It has a. This coating film 1a is made of materials such as alkyd resin paint, melamine alkyd resin paint, acrylic resin paint, polyurethane resin paint, epoxy paint, polyester resin paint, cool epoxy resin paint, etc., which is baked, dried at room temperature, and powdered. It is formed by body painting. This coating film 1a, together with the fluororesin coating layer 2, provides the metal plate A with weather resistance and corrosion resistance, and also serves as the base color of the metal plate A. For this reason, if the color is the same as that of the fluororesin coating layer 2, the color unevenness of the metal plate A is eliminated, and if the fluororesin coating layer 2 is transparent, the color of the coating film 1a is directly applied to the metal plate. Alternatively, if it is different from the fluororesin coating layer 2, the color of the coating film 1a can be made into a stand-out color. Note that the color steel plate 1 is a flat plate,
Either embossed plate may be used. Fluororesin coating layer 2 is a fluororesin paint, such as a mixture of fluororesin and acrylic resin, a copolymer of polyethylene resin and fluororesin, a copolymer of polyethylene resin and fluororesin mixed with acrylic resin, etc. It is made from colored or colorless fluororesin paint. To explain further, the fluororesin coating layer 2 improves the weather resistance and corrosion resistance of the metal plate A, prevents the occurrence of rust, and enables long-term use. The thickness of the fluororesin coating layer 2 is arbitrary, but even if it is as thin as 5μ, the color of the coating 1a will be the base.
There is no uneven color, and it is possible to enhance the eating ability and eating ability. In addition, when the embossed pattern 3 is provided on the metal plate A as shown in FIG. 2, the fluororesin coating layer 2 may be formed after embossing the color steel plate 1, or
Embossing can be performed after forming the fluororesin coating layer 2, but the former is preferable because it can cover even the cracked portions when cracks occur in the coating 1a due to embossing. .
