った。Therefore, conventionally, aluminum, copper, etc. on the wall surface of a building or the like having a surface such as cement mortar or asbestos slate,
A method is known in which a metal base material such as nickel is thinly sprayed by an electro-spraying method, and then a glass powder material having a particle size of about 74 μm is plasma sprayed to form a glassy coating film of about 0.2 mm. (See Japanese Patent Laid-Open No. 60-12177) Problems to be Solved by the Invention The conventional method of spraying a metal on a wall surface and forming a glass film thereon is a metal thin film on a non-combustible material such as cement mortar. The point of spraying is the same as the technique in this invention, but since the glass powder material with a particle size of about 74μ is plasma sprayed to form the glass coating on the metal thin film, the whole is melted in the case of metal powder, The glass powder is in a state in which granular materials whose surface is only melted are laminated with a thickness of about 0.2 mm, and a gap is formed between the glass powder and the adjacent glass powder,
Since the pinhole phenomenon occurs, the metal coating is corroded by rainwater, resulting in a loss of gloss and durability.

After the coating, a metallic luster that forms a glass thin film by coating a solution of fine powder of metal alcoholate such as ethyl silicate with ethyl alcohol and water on the upper surface and heating at 100 ° C for about 30 minutes. It is a method of manufacturing an exterior material having a surface.

外装材を得ることができる。(1) is a precast concrete panel which is a base material, and a stainless steel thin film (2) having a thickness of 150 μ is deposited on the surface thereof. As the metal of the thin film (2), aluminum, copper, titanium, nickel, cobalt or the like can be appropriately used in addition to stainless steel.
The above-mentioned stainless steel thin film is sprayed by a metal spraying machine, and the thickness is as thin as 150 μ, so that it is 5-10.
Since it has a porosity of%, an amorphous glass thin film (3) with a thickness of 50 μm is further formed on the upper surface of the stainless steel thin film (2) in order to provide its sealing treatment, corrosion resistance and luster. ing. By doing so, since the metal surface is covered with the transparent thin film having no pinhole, it is possible to obtain the exterior material of the precast concrete panel having the metal glossy surface which is not corroded by the outside air or rainwater.

The concrete surface of this panel was blasted by a sandblasting machine, and then a stainless steel granular material having a particle size of 10 to 50 μm was sprayed on the concrete surface to a thickness of 150 μm by a metal spraying machine. At this time, the concrete surface is heated by the stainless steel melt, but it does not adversely affect the concrete only by raising the temperature by about 100 ° C. The stainless steel melt is mechanically bonded to the concrete surface due to the speed of the thermal spray. However, it has an adhesive strength substantially equal to the tensile strength of concrete. The thickness of the sprayed metal is preferably 50 to 200 μm.

外装材を容易に製造することができる。EFFECTS OF THE INVENTION In the method of manufacturing an exterior material of the present invention, thermal spraying of various metals by a metal sprayer causes mechanical adhesion to a concrete surface or the like at a relatively low temperature of around 100 ° C., so that the material of the adhesive surface is physically changed. It has a strong adhesive strength without causing peeling and is robust without peeling. A glass thin film is formed on the upper surface of the metal thin film by a chemical reaction at a relatively low temperature of around 100 ° C, which adversely affects the adhesion state of the metal thin film. It is possible to form a thin film of amorphous glass that does not have pinholes and has a thin film thickness of 20 to 200μ in a short time, and rainwater does not permeate into the metal thin film below it, which is durable. Since the metal thin film has a good property and the metal thin film is completely protected, an exterior material such as a concrete panel having a metallic glossy surface can be easily manufactured.
