These usually undergo discoloration, deterioration of the decorative coating, cracking, cracking, and peeling over time due to exposure to ultraviolet rays, etc., and are accompanied by the generation of rust. For this reason,
Metal plates using fluororesin paints with good weather resistance are also on the market. However, fluororesin-based paints are expensive, and even when fluororesin-based paints are used, they require preparation of the substrate, primer treatment, undercoating, (intermediate coating), and topcoating, so they have the disadvantage of being expensive compared to the added value. there were. In addition, fluororesin paints have the disadvantage that there are restrictions on the pigments (colorants) that can be used, and metal plates cannot be made into arbitrary colors. Furthermore, fluororesin paints generally have poor adhesion to synthetic resin paints such as epoxy resin paints, and will peel off if simply applied, making it impossible to improve the weather resistance of the fluororesin coating. there were.

The present invention proposes a metal plate that can be formed at a low cost while strengthening adhesion and improving weather resistance and corrosion resistance by forming the metal plate after activation with a system emuldigon or the like.

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, 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 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 an electrolytic chromic acid treated steel plate, a stainless steel plate, an aluminum alloy plate, a zinc alloy plate, a titanium plate, etc., and both surfaces are subjected to primer treatment, and at least the decorative surface has a decorative coating 1a. This coating film 1a includes alkyd resin paint, melamine alkyd resin paint, acrylic resin paint, polyurethane resin paint, epoxy paint,
Polyester resin paint, tar epoxy resin paint,
It is formed by baking, drying at room temperature, and powder coating a material such as silicone paint. This makeup coating 1a
works together with the fluororesin coating layer 2 to impart weather resistance and corrosion resistance to the metal plate A, 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 will be eliminated, and if the fluororesin coating layer 2 is transparent, the color of the decorative coating 1a will be used as the color of the metal plate A. , or when it is different from the fluororesin coating layer 2, the color of the decorative coating film 1a can be made to stand out. Note that the color steel plate 1 may be either a flat plate or an embossed plate. The fluororesin coating layer 2 is a fluororesin paint, for example, a fluororesin paint using tetrafluoroethylene, hexafluoropropylene copolymer, polyvinyl fluoride, fluoroolefin copolymer resin, etc., or a mixture of fluororesin and acrylic resin. , a copolymer of polyethylene resin and a fluororesin, and a fluororesin paint made of a mixture of a copolymer of a polyethylene resin and a fluororesin with an acrylic resin, etc., and may be colored or colorless. be. This fluororesin coating N2 is intended to improve the weather resistance and corrosion resistance of the metal plate A, prevent the occurrence of rust, and enable long-term use. To explain further, the fluororesin coating layer 2 is formed after activating the surface of the decorative coating 1a. That is, simply applying a fluororesin-based paint on the decorative coating layer la will result in a weak adhesive force between the decorative coating layer 1a and the fluororesin coating layer 2. The adhesion between the decorative coating film 1a and the fluororesin coating layer 2 is improved by activating it using at least one of treatment, anion treatment, chemical conversion treatment such as acid and alkali, and applying a fluororesin paint thereon. Strengthens adhesion. In this case, at the interface between the decorative coating film 1a and the fluororesin coating layer 2, the adhesive area of the decorative coating film 1a is increased due to the unevenness caused by the activation treatment, and an anchor effect is created due to the unevenness. 1a and the fluororesin coating layer 2 are partially mixed and chemically bonded, increasing adhesive strength and adhesion, and preventing peeling. Note that the thickness of the fluororesin coating layer 2 is arbitrary, but even if it is as thin as 5μ, for example, the color of the decorative coating 1a will be the base, so there will be no color unevenness and the weather resistance and corrosion resistance will be enhanced. can do. In addition, the fluororesin coating layer 2
When providing the embossed pattern 3 on the metal plate A as shown in FIG. 2, it can be formed after embossing the color steel plate 1, or the embossing can be performed after forming the fluororesin coating N2. The former is preferable because, when cracks occur in the coating film 1a due to embossing, the crank portion can also be covered.
