沢や色が変化する欠点があつた。 This type of architectural panel is widely used by coating a metal base with a colored paint film, but because the colored paint film has low hardness, it is easily scratched and rusts from there, and the colored paint film is generally The drawback was that it was difficult to create a stable color freely because weather resistance and other properties changed depending on the type of pigment. Therefore, materials made of enameled metal plates that can produce stable colors freely and have a high surface hardness have been used, but the enameled layer has poor weather resistance and has the disadvantage of changing gloss and color.

が好ましい。 Main body 1 made of enameled metal plate material in the present invention
What is enamel glaze, which is made by adding the necessary pigments to lead, borosilicate glass, etc. on the surface of the metal base 2, which is made by cutting cold-rolled steel plates, aluminized steel plates, aluminum plates, etc. into the required shapes and performing sheet metal processing as necessary. The main body 1 has a well-known enamel layer 3 which is glazed and fired, and since the enamel layer 3 has poor weather resistance, the luster and color of the main body 1 will change if it is used as an exterior material. Therefore, in the present invention, in order to prevent changes in the gloss and color of the enamel layer 3, a baked coating 4 of transparent synthetic resin such as fluororesin, silicone resin, acrylic resin, etc., which has excellent weather resistance and relatively good surface hardness, is layered. It has been experimentally confirmed that when this baked coating 4 is applied directly to the surface of the enamel layer 3, the adhesive strength is low and it peels off in accelerated tests such as salt spray tests. In order to improve the properties, adhesion to both the enamel layer 3 made of a silicone resin such as a silane coupling liquid or silicone oil or an epoxy resin and the baked coating 4 made of a transparent synthetic resin is extremely good.
A transparent material that can withstand the baking temperature is first coated with an enamel layer 3.
A transparent synthetic resin thin film layer 5 is formed extremely thinly by coating on the surface of the enamel layer 3, and the above-mentioned transparent synthetic resin baked coating 4 is integrally layered on the enamel layer 3 via this transparent synthetic resin thin film layer 5. do. In addition, 7 in the figure is an aluminized layer provided as necessary on the surface of the metal base 2 when it is a steel plate material, and in this way, the main body 1 made of an enameled metal plate has at least the surface of the metal base 2. When it is made of an aluminized steel plate or an aluminum plate such as aluminum, the adhesion with the enamel layer 3 is extremely good, so the impact resistance and bending resistance are extremely good, and the thickness of the enamel layer 3 is also reduced. It should be about 30 to 400 μ, but
In consideration of impact resistance and bending resistance, the thickness is preferably 200μ or less. Next, a transparent synthetic resin thin film layer 5 deposited on the surface of this main body 1 is coated with an enamel layer 3.
Since this is necessary to improve the adhesion between the enamel layer 3 and the baked coating 4, it can be made extremely thin by spraying or the like. It is preferable to form the surface into a finely roughened surface 6 by using, for example, a .

とがなく、長期耐用できる利点がある。 In this structure, a baked coating 4 of a transparent synthetic resin having excellent weather resistance is applied to an enameled layer 3 formed on the surface of a main body 1 made of an enameled metal plate, with a transparent synthetic resin thin film layer 5 interposed therebetween. Since the enamel layer 3 is integrally layered, the color of the enamel layer 3 can be seen through the baked coating 4 and the synthetic resin thin film layer 5.
Since the baked coating 4 on the surface protects the enamel layer 3, scratches are unlikely to reach the metal base 2 of the main body 1, and there is almost no risk of rusting. The coating 4 is extremely superior because it does not contain pigments that degrade weather resistance, and its luster and color do not deteriorate over time, allowing the characteristics of the enamel layer 3 to freely produce stable colors to be maintained over a long period of time. The color of the enamel layer 3, which can be seen through the two transparent layers, has a deep color.
Moreover, the baked coating 4 made of transparent synthetic resin is not directly attached to the enamel layer 3, but is attached to the baked coating 4.
Since a transparent synthetic resin thin film layer 5 with good adhesion to both the enamel layer 3 and the enamel layer 3 is interposed between the two,
There is an advantage that the baked coating 4 does not peel off due to bending of the main body 1, and can be used for a long time.

A colorless and transparent silane coupling liquid was applied and dried to form a transparent synthetic resin thin film layer.Furthermore, transparent fluororesin was sprayed on the surface to a film thickness of 30μ and baked at approximately 300℃. . The box-shaped architectural panels obtained in this way showed no abnormality in gloss or color tone even after 1,000 hours of weather meter testing and 1,000 hours of salt spray testing, and there was no rust. The color was free and stable, and there was almost no change over time.

た。Example 2 After forming a borosilicate glass-based enamel layer with a film thickness of 80μ on a flat aluminized steel plate with a wall thickness of 0.8mm cut into squares, a colorless and transparent liquid epoxy resin was applied.
Dry to form a transparent synthetic resin thin film layer, then spray approximately 30μ of transparent acrylic resin onto the surface and bake at approximately 200°C to form a transparent synthetic resin baked film, which is then shaped into a box. It was processed into sheet metal and made into architectural panels. This architectural panel is able to produce free and stable color due to the enamel layer, and it also has a weather meter of 1000 hours and salt water spray.
Even after 1000 hours, there was no abnormality in gloss, color tone, etc., and there was no rust, and even though it was post-processed into a box shape, the baked coating on the bent part did not peel off.
