Modes for Carrying Out the Invention

[0017] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figures 1 and 2 show the corrosion-resistant mirror according to the embodiment of the present invention. As shown in FIGS. 1 and 2, the corrosion-resistant mirror includes a plate mirror 1, an airtight substrate 2, an adhesive 3, an airtight material 4, and a desiccant 5.

[0018] The plate mirror 1 is formed by providing a silver mirror film layer 1b on the back side of a glass plate 1a. The glass plate 1a has a vertically long rectangular outer shape as an example, but may have any shape such as circular, elliptical, or others. The glass plate 1a has an inclined surface 1c with a cutout shape from the back surface to the peripheral end surface. The plate mirror 1 has an airtight film 1d that covers the entire back side with the silver mirror film layer 1b. The airtight substrate 2 has the same size and shape as the glass plate 1a of the plate mirror 1 and is made of a float glass plate thinner than the glass plate 1a of the plate mirror 1. The airtight substrate 2 has a thickness of 3 mm or more and 8 mm or less as an example. The back surface of the airtight substrate 2 is adhered to the wall surface 9 by an adhesive silicon material 2a.

[0019] The adhesive 3 is composed of a double-sided adhesive mat having a predetermined thickness with airtightness. As shown in FIG. 2, the adhesive 3 forms a rectangular ring along the outer shapes of the airtight substrate 2 and the plate mirror 1. The adhesive 3 is provided in a rectangular frame shape at a position inside the peripheral edge portion 11 of the airtight substrate 2 and the plate mirror 1 by a predetermined distance. The adhesive 3 adheres the back side of the plate mirror 1 and the front side surface of the airtight substrate 2. The adhesive 3 has a thickness of 3 mm or more and 12 mm or less as an example.

[0020] The airtight material 4 is composed of glass silicon caulking. The airtight material 4 forms a ring to cover the boundary portion between the glass plate 1a and the silver mirror film layer 1b and airtightly connects and adheres the peripheral edge portion 11 of the plate mirror 1 and the peripheral edge portion of the airtight substrate 2. The adhesive 3 is provided inside the plate mirror 1 from the airtight material 4. The airtight material 4 forms a hollow layer 6 of air surrounded by the plate mirror 1 and the airtight substrate 2 inside the ring shape. A desiccant 5 is provided in the hollow layer 6. The double-sided adhesive mat may have a function of a desiccant. The plate mirror 1 is further adhered to the front side of the airtight substrate 2 by an adhesive silicon material 7 at the center of the hollow layer 6 on the back side. The corrosion-resistant mirror can be attached to the wall surface 9 or the like by a mirror fitting 8.

[0021] Next, a method for installing a corrosion-resistant mirror according to an embodiment of the present invention will be described. FIG. 3 shows a corrosion-resistant mirror constructed by the method for installing a corrosion-resistant mirror according to an embodiment of the present invention. In FIG. 3, the same parts as those in FIGS. 1 and 2 are denoted by the same reference numerals, and redundant descriptions are omitted.

[0022] In this method for installing a corrosion-resistant mirror, a new plate mirror 1 is attached onto an airtight substrate 2 attached to a wall surface 9. The airtight substrate 2 is composed of an existing old plate mirror deteriorated by moisture. The airtight substrate 2 has its back surface adhered to the wall surface 9 by an adhesive silicon material 2a and is further fixed to the wall surface 9 by an existing mirror receiver 2b. The plate mirror 1 is formed by providing a silver mirror film layer 1b on the back side of a glass plate 1a made of a float glass plate. The glass plate 1a has a chamfered inclined surface 1c with a notched shape by chamfering from the back surface to the peripheral end surface. The plate mirror 1 has an airtight film 1d covering the entire back side with the silver mirror film layer 1b.

[0023] In the pasting step, the back side of the plate mirror 1 and the front side surface of the airtight substrate 2 are adhered with an adhesive 3. The adhesive 3 is composed of a double-sided adhesive mat having a predetermined thickness and having airtightness. The adhesive 3 is provided so as to form a rectangular ring along the outer shapes of the airtight substrate 2 and the plate mirror 1. At the same time, in the airtightness step, an airtight material 4 annularly covers the boundary between the glass plate 1a and the silver mirror film layer 1b and airtightly connects and adheres the peripheral portion 11 of the plate mirror 1 and the peripheral portion of the airtight substrate 2. The airtight material 4 has a hollow layer 6 of air surrounded by the plate mirror 1 and the airtight substrate 2 inside the annular shape. The adhesive 3 is provided inside the plate mirror 1 from the airtight material 4. Further, the back side of the plate mirror 1 and the front side of the airtight substrate 2 are adhered at the center of the hollow layer 6 by an adhesive silicon material 7. At the same time, in the desiccant installation step, a desiccant 5 is provided in the hollow layer 6.

[0024] In this way, a corrosion-resistant mirror can be applied onto the deteriorated old plate mirror. After polishing the mirror surface of the corrosion-resistant mirror that has undergone product processing or the like with a glass surface coating treatment agent, a coating processing agent is applied to the mirror surface. A cerium abrasive is used as the glass surface coating treatment agent. Liquid soap is used as the coating processing agent. As the liquid soap, those containing a ceramide moisturizing component, alcohol, a preservative, a natural-derived amino acid-based cleaning component, etc. are preferable. By polishing the mirror surface with a glass surface coating treatment agent, the surface tension of the mirror surface becomes smaller. And by applying a coating processing agent to the mirror surface, it is possible to prevent uroco stains derived from mineral components such as calcium and silicon contained in tap water for a long period of time.

[0025] In the corrosion-resistant mirror and the method for applying the corrosion-resistant mirror according to the embodiment of the present invention, since the boundary portion between the glass plate 1a and the silver mirror film layer 1b is covered by the airtight material 4, it is possible to suppress moisture and humidity from entering between the silver mirror film layer 1b and the glass plate 1a from the boundary portion and causing the mirror surface to turn black. In particular, since the glass plate 1a has an inclined surface 1c formed by chamfering from the back surface to the peripheral end surface, the adhesion surface of the airtight material 4 becomes larger and the airtightness is further enhanced. Note that the inclined surface 1c may not be provided.

[0026] Also, since the airtight material 4 airtightly connects the peripheral portion 11 of the plate mirror 1 and the peripheral portion of the airtight substrate 2, it is difficult for external moisture and mold to enter between the plate mirror 1 and the airtight substrate 2, and the deterioration prevention effect due to moisture and mold is enhanced. In particular, although tap water and hot spring water contain acidic or alkaline components that corrode the silver mirror film layer 1b, the airtight material 4 prevents them from infiltrating, and it is possible to prevent the deterioration of the plate mirror 1 even in a bathing facility such as a hot spring. Further, the desiccant 5 in the hollow layer 6 absorbs the moisture in the hollow layer 6, and the deterioration of the silver mirror film layer 1b can be further suppressed. Since the plate mirror 1 has an airtight film 1d that covers the entire back surface with the silver mirror film layer 1b, the deterioration of the entire silver mirror film layer 1b can be further suppressed by the airtight film 1d. Plate mirrors in washrooms and bathing facilities often deteriorate in one or two years, but the corrosion-resistant mirror according to the embodiment of the present invention can prevent deterioration for a long period of time.

[0027] In the construction method of the corrosion-resistant mirror, a new plate mirror 1 is attached onto the deteriorated plate mirror. When replacing the plate mirror deteriorated by moisture with a new plate mirror 1, if the deteriorated plate mirror is removed from the wall surface 9 and a new plate mirror 1 is newly attached, removal work and disposal of the old plate mirror are required, resulting in increased construction costs. However, in the construction method of the corrosion-resistant mirror according to the embodiment of the present invention, since the deteriorated old plate mirror is used as the airtight substrate 2, removal work and disposal of the old plate mirror are not required, and reduction of construction costs can be achieved.

[0028] FIG. 4 and FIG. 5 show corrosion-resistant mirrors according to other embodiments of the present invention. In FIG. 4 and FIG. 5, the same parts as those in FIGS. 1 to 3 are denoted by the same reference numerals, and redundant descriptions are omitted. As shown in FIGS. 4 and 5, the corrosion-resistant mirror has a plate mirror 1, an airtight substrate 2, an adhesive 3, and an airtight material 4.

[0029] The plate mirror 1 is formed by providing a silver mirror film layer 1b on the back side of a glass plate 1a. The silver mirror film layer 1b is provided inside at a predetermined distance from the peripheral edge portion 11 on the back side of the glass plate 1a. For this reason, the silver mirror film layer 1b has an outer shape smaller than the outer shape of the glass plate 1a. The predetermined distance is preferably 7 mm or more and 15 mm or less. The plate mirror 1 has an airtight film 1d covering the silver mirror film layer 1b on the entire back side. The airtight substrate 2 is made of a float glass plate having the same size and shape as the glass plate 1a of the plate mirror 1 and being thinner than the glass plate 1a of the plate mirror 1.

[0030] The adhesive 3 is composed of a double-sided adhesive mat having a predetermined thickness and having airtightness. The double-sided adhesive mat has a function of a desiccant for the mat to absorb moisture and humidity. As shown in FIG. 4, the adhesive 3 forms a double rectangular ring along the outer shapes of the airtight substrate 2 and the plate mirror 1. The adhesive 3 is provided in a rectangular double frame shape at a position inside a predetermined distance from the peripheral edge portion 11 of the airtight substrate 2 and the plate mirror 1. The adhesive 3 adheres the back side of the plate mirror 1 and the front side surface of the airtight substrate 2.

[0031] The airtight material 4 is made of silicon caulking for glass. The airtight material 4 annularly covers the entire edge 1e between the peripheral edge 11 on the back side of the glass plate 1a and the silver mirror film layer 1b and the outer periphery of the silver mirror film layer 1b, and airtightly connects and adheres the entire edge 1e and the front side surface of the airtight substrate 2. The airtight material 4 forms a hollow layer 6 surrounded by the plate mirror 1 and the airtight substrate 2 on the annular inner side. The adhesive 3 is provided in the hollow layer 6 inside the plate mirror 1 from the airtight material 4. The corrosion-resistant mirror can be attached to a wall surface 9 or the like by a mirror holder 8.

[0032] Next, the construction method of the corrosion-resistant mirror shown in FIGS. 4 and 5 will be described. The plate mirror 1 is formed by providing a silver mirror film layer 1b on the entire back side of a glass plate 1a made of a float glass plate. First, in the silver mirror film removal step, the entire peripheral silver mirror film layer 1b is peeled off and removed along the peripheral edge 11 of the plate mirror Ⅰ with a predetermined width of 7 mm or more. Next, an airtight film 1d that covers the silver mirror film layer 1b is attached to the back side of the plate mirror 1. A gap with a predetermined width is provided between the outer periphery of the airtight film 1d and the peripheral edge 11 of the plate mirror 1.

[0033] In the attaching step and the desiccant installation step, the back side of the plate mirror 1 and the front side surface of the airtight substrate 2 are adhered with an adhesive 3. The adhesive 3 is composed of a double-sided adhesive mat with a predetermined thickness having airtightness. The double-sided adhesive mat has the function of a desiccant for the mat to absorb moisture and humidity. The adhesive 3 is provided so as to form a rectangular ring along the outer shapes of the airtight substrate 2 and the plate mirror 1. At the same time, in the airtightness step, the airtight material 4 annularly covers the entire edge 1e where the silver mirror film layer 1b has been removed between the peripheral edge 11 on the back side of the glass plate 1a and the silver mirror film layer 1b and the outer periphery of the silver mirror film layer 1b, and airtightly connects and adheres the entire edge 1e and the front side surface of the airtight substrate 2.

[0034] The airtight material 4 has a hollow layer 6 surrounded by the plate mirror 1 and the airtight substrate 2 on the inside in an annular shape. The adhesive 3 is provided inside the plate mirror 1 from the airtight material 4. Further, the back side of the plate mirror 1 and the front side of the airtight substrate 2 are adhered at the center of the hollow layer 6 by the adhesive silicon material 7. The manufactured corrosion-resistant mirror 1 is attached to a wall surface 9 or the like by a mirror receiver 8. In this way, the corrosion-resistant mirror 1 can be installed. After installing the corrosion-resistant mirror 1, the mirror surface of the corrosion-resistant mirror 1 is polished with a glass surface coating treatment agent, and then a coating processing agent is applied to the mirror surface.

[0035] In the corrosion-resistant mirror and the installation method of the corrosion-resistant mirror shown in FIGS. 4 and 5, the silver mirror film layer 1b is provided inside, away from the peripheral edge portion 11 on the back side of the glass plate 1a. Since the entire edge portion 1e between the peripheral edge portion 11 on the back side of the glass plate 1a and the silver mirror film layer 1b and the outer periphery of the silver mirror film layer 1b are covered with the airtight material 4, it is possible to suppress moisture and humidity from entering between the silver mirror film layer 1b and the glass plate 1a from the peripheral edge portion 11 and causing the mirror surface to turn black.

[0036] Also, since the airtight material 4 airtightly connects the entire edge portion 1e and the front side surface of the airtight substrate 2, it is difficult for external moisture and mold to enter between the plate mirror 1 and the airtight substrate 2, and the deterioration prevention effect due to moisture and mold is enhanced. When the plate mirror 1 is viewed from the front side, the airtight material 4 can be seen through in a frame shape from the entire edge portion 1e of the glass plate 1a, giving the appearance of a frame. The airtight material 4 that appears in a frame shape may be colored or decorated on the side visible from the front side of the plate mirror 1. A part of the silver mirror film layer 1b on the back surface of the plate mirror 1 may be peeled off, and a photo or the like having a healing effect may be pasted on the peeled portion so as to be visible from the front side.

In FIG. 6, the same parts as those in FIG. 4 are denoted by the same reference numerals, and redundant descriptions are omitted. In the corrosion-resistant mirror shown in FIG. 6, the airtight substrate 2 is formed of a wall, and the plate mirror 1 is fixed to the airtight substrate 2 by a mirror receiver 8. In this way, even when the airtight substrate 2 is formed of a wall, the deterioration prevention effect of the corrosion-resistant mirror can be enhanced.
