反射鏡なのである。However, although this reflecting mirror can be used for general indoor use, it is used in environments (pools, hot springs, toilets, kitchens) containing trace amounts of corrosive gases such as Cl 2 , H 2 S and NH 3. Etc.), humid environment (bathroom etc.) and salt water environment (coastal zone). This is because it is difficult to eliminate pinholes in the protective film that protects the reflecting surface, and the pinholes in the protective film have reduced environmental resistance such as corrosion resistance. It is a reflector that is suitable only for a good environment.

ない。If the protective film is thickened, the occurrence of pinholes can be suppressed. However, when the protective film is thickened, the reflectance of the mirror as a whole is lowered, the durability of the protective film is lowered, and the manufacturing cost is reduced. Another issue of rise comes up. On the other hand, from the viewpoint of the reflectance of the reflecting mirror, the bright metal film is preferably a silver film rather than an aluminum film. This is because the reflectance of the silver film is higher by about 10%. However, since the silver film is much more active than the aluminum film, the environmental resistance is very low. Therefore, in particular, a reflecting mirror using a silver film is not suitable for use in the above-mentioned bad environment, and it can be used only in a particularly good environment even in a general indoor environment, and its application is limited. However, it is rarely used as a reflector for general lighting equipment.

れる。Hereinafter, the reflecting mirror of the present invention will be specifically described with reference to FIG. 1 showing an example of the configuration thereof. Examples of the substrate 2 used in the reflecting mirror 1 of the present invention include a metal substrate, a plastic substrate, and a glass substrate. The metal substrate is exemplified by a plate-shaped material such as Al (aluminum), Al alloy, Fe (iron), Fe alloy, and SUS finished into a predetermined mirror shape by a molding method such as press molding or spatula drawing. It In the case of a reflecting mirror using a metal substrate, it is preferable to carry out a surface treatment such as chemical polishing or electrolytic polishing after the cloth covering is polished. For plastic and glass substrates, plastic materials (polycarbonate, nylon,
Examples include those obtained by finishing a predetermined mirror shape by die molding (injection molding or press molding) of a glass material such as polyimide).

い。An undercoating 3 is applied to the above substrate 2 (in the case of a glass substrate, the undercoating may be omitted), and a bright metal film 4 containing a fluorine compound in the film is used as a reflecting film thereon. Form. The bright metal film is preferably a silver film, but is not limited to this and may be an aluminum film or the like. A silver film containing a fluorine compound can be produced by depositing and forming an Ag layer in a gas atmosphere of a low molecular weight fluorine compound using a vacuum deposition method, an ion plating method, a sputtering method, or the like. It goes without saying that the silver film in which the fluorine compound is mixed is not limited to the above-described film forming method.

If it is less than 3, it is difficult to obtain a sufficient reflectance, and if it exceeds 3000 Å, the effect of improving the reflectance is not observed, the time required for film formation becomes long, and the cost also becomes high.

A protective film 5 is further formed on the above. The protective film is preferably a coating film of a moisture-curable silicone acrylic resin material. This is because the use of a curable silicone acrylic resin-based material is preferable in terms of minimizing the water content of the silver film, forming a coating film having a high gas barrier property, and improving the environmental resistance of the reflecting mirror. Examples of the method for forming the protective film include a spray method, a flow coating method, a dipping method, and the like, but any method capable of forming a uniform coating film may be used. The thickness of the protective film is usually 20 to 3 in consideration of reflectance and corrosion resistance.
It is about 0 μm.
