Description

  The present invention relates to a method for manufacturing a luminous phosphor used for, for example, a sign for evacuation guidance or a glass tile for decoration.

In general, glass tiles displaying signs for evacuation guidance are installed on roads and sidewalks, or on walls and floors in buildings such as hotels, department stores, and various public facilities. On the surface of the glass tile, a figure such as an arrow indicating the guiding direction is displayed using a phosphorescent material, and the display unit is caused to emit light in the dark by the phosphorescent material. However, in the case where the display unit is displayed on the surface of the glass tile, the phosphorescent material is exposed to the outside. is there. Therefore, assuming that the phosphorescent material is not exposed to the outside, the frit is melted by heating with a mixture of phosphorescent material and powdered frit between a plurality of laminated glass sheets. What is made to adhere | attach each sheet glass is known (for example, refer patent document 1).
JP-A-9-278396

  By the way, as for the phosphorescent material, the large particle shape (100 μm to 200 μm) has a higher light emitting property than the small particle shape (100 μm or less), and is suitable for use as an evacuation guidance sign or the like. Since the phosphorescent layer is formed by applying phosphorescent material to the surface of each sheet glass that touches each other, if a large-sized phosphorescent material is used, the phosphorescent layer is stabilized between the sheet glasses due to the unevenness of the phosphorescent material. There is a problem in that it cannot be formed and manufacturing becomes difficult.

  The present invention has been made in view of the above-described problems, and the object of the present invention is to provide a phosphorescent property capable of always stably forming a phosphorescent layer serving as a light emitting part even when a large-grain phosphorescent material is used. It is providing the manufacturing method of a light-emitting body.

  In order to achieve the above-mentioned object, the present invention provides a method for producing a luminous phosphor, in which a light emitting portion made of a phosphorescent material is formed inside a plate-like portion made of a glass material. After forming the first glass layer to be a part of the plate-like portion on the surface of the holding member, the phosphorescent layer to be the light emitting portion is formed on the first glass layer of the temporary holding member and temporarily held. A second glass layer that forms part of the plate-like portion is formed on the first glass layer and the luminous layer of the member, and the first glass layer, the luminous layer, and the second glass layer are removed from the temporary holding member. A plate-like portion and a light emitting portion are formed by peeling and baking together with another glass material.

  Thereby, after the 1st glass layer used as a part of plate-shaped part is formed in the surface of a temporary holding member, the luminous layer used as a light emission part is formed on the 1st glass layer, and 1st A second glass layer that becomes a part of the plate-like portion is formed on the glass layer and the phosphorescent layer, and the first glass layer is peeled off from the temporary holding member together with the phosphorescent layer and the second glass layer, Since the plate-like part and the light-emitting part are formed by firing together with the glass material, the phosphorescent layer is stabilized on the temporary holding member together with the first and second glass layers even when a large-grain phosphorescent material is used. Can be formed.

  According to the present invention, even when a large-grain phosphorescent material is used, a phosphorescent layer serving as a light-emitting portion can always be stably formed. Therefore, it is possible to easily manufacture a phosphorescent phosphor having excellent luminous performance. it can.

  FIG. 1 to FIG. 10 show an embodiment of the present invention, FIG. 1 is a perspective view of a luminous phosphor, FIGS. 2 to 8 are perspective views showing the manufacturing process, and FIG. 9 and FIG. It is side surface sectional drawing which shows a process.

  This luminous phosphor is composed of a transparent plate-like portion 1 and a light-emitting portion 2 formed inside the plate-like portion 1, for example, as a sign for evacuation guidance installed on a floor surface or a wall surface in a building. Used. The plate-like portion 1 is formed by forming a glass material in a tile shape, and the light-emitting portion 2 can be seen through from the outside. The light emitting section 2 is formed by forming a granular phosphorescent material into a sheet shape so as to form a predetermined figure, and a known phosphor that absorbs external light and emits light in the dark is used.

  Next, the manufacturing method of the said luminous luminous body is demonstrated. First, as shown in FIG. 2 and FIG. 9 (a), a temporary holding member 3 (for example, cardboard) having a water-soluble surface layer 3a (for example, dextrin) formed on one surface is prepared. A temporary holding member is applied as shown in FIGS. 3 and 9 (b) by applying a non-illustrated adhesive and adhering a glass material (for example, a glass frit having a smaller particle size than the phosphorescent material and a solvent). A first glass layer 1 a to be a part (lower side) of the plate-like portion 1 is formed on the substrate 3. Next, by applying an adhesive on the first glass layer 1a and adhering the mixture of the granular phosphorescent material and the solvent, the first glass layer as shown in FIG. 4 and FIG. 9 (c). A phosphorescent layer 2a to be the light emitting unit 2 is formed on 1a. In this case, a large particle (100 μm to 1000 μm) phosphorescent material is used. Thereafter, an adhesive is applied onto the first glass layer 1a and the phosphorescent layer 2a, and the same glass material as that of the first glass layer 1a is adhered, as shown in FIG. 5 and FIG. 9 (d). The second glass layer 1b which becomes a part (upper side) of the plate-like portion 1 is formed on the first glass layer 1a and the phosphorescent layer 2a. Next, the temporary holding member 3 holding the first glass layer 1a, the phosphorescent layer 2a and the second glass layer 1b is immersed in water to melt the surface layer 3a, as shown in FIGS. 6 and 9 (e). Thus, the 1st glass layer 1a is peeled from the temporary holding member 3 with the luminous layer 2a and the 2nd glass layer 1b. Thereafter, as shown in FIGS. 7 and 10 (a), another glass material (for example, pulverized glass) is laid in the firing mold 4 (for example, mullite-based fired product), and the lower third glass layer 1c. After forming, the 1st glass layer 1a, the luminous layer 2a, and the 2nd glass layer 1b are mounted on the 3rd glass layer 1c. Subsequently, as shown in FIGS. 8 and 10 (b), the same glass material on the third glass layer 1c, the first glass layer 1a, the phosphorescent layer 2a and the second glass layer 1b in the mold 4 is used. (E.g., crushed glass) is spread to form the upper third glass layer 1c and fired at a predetermined temperature (900 ° C. to 940 ° C.), so that the plate-like portion 1 and the light emission as shown in FIG. Part 2 is formed. At that time, the glass layers 1a, 1b, and 1c are melted to form the plate-like portion 1 in the firing mold 4, and the light-emitting portion 2 is formed in the plate-like portion 1 so as to be covered with the glass material. The

  Thus, according to this embodiment, after forming the 1st glass layer 1a used as a part of plate-shaped part 1 on the surface of the temporary holding member 3, the light emission part 2 on the 1st glass layer 1a. And the second glass layer 1b which becomes a part of the plate-like portion 1 is formed on the first glass layer 1a and the phosphorescent layer 2a, and the first glass layer 1a is phosphorescent. Since the plate-like portion 1 and the light-emitting portion 2 are formed by peeling off the temporary holding member 3 together with the layer 2a and the second glass layer 1b and firing together with the other glass material, a large-sized phosphorescent material is used. Even in this case, the phosphorescent layer 2a can be always stably formed on the temporary holding member 3 together with the first and second glass layers 1a and 1b, and a phosphorescent phosphor having excellent luminous performance is easily manufactured. be able to.

  Also, by forming the first glass layer 1a, the phosphorescent layer 2a and the second glass layer 1b on the surface of the temporary holding member 3 having the soluble surface layer 3a, and melting the surface layer 3a of the temporary holding member 3 Since the first glass layer 1a is peeled off from the temporary holding member 3, the glass material of the first glass layer 1a is not left on the surface of the temporary holding member 3, and the first glass layer 1a is temporarily held. It can be reliably separated from the member 3.

  In this case, since the water-soluble material is used for the surface layer 3a of the temporary holding member 3, and the temporary holding member 3 is immersed in water to melt the surface layer 3a, the peeling operation can be easily performed. The production efficiency can be improved.

  In addition, since the third glass layer 1c is formed with another glass material on the first glass layer 1a side and the second glass layer 1b side, and is put into a predetermined firing mold 4 and fired, The 3rd glass layer 1c used as the surface side of the plate-shaped part 1 can be shape | molded in a desired shape, and the plate-shaped part 1 of arbitrary shapes can always be formed appropriately. In this case, when it is desired to thinly form the plate-like portion 1 on one surface side of the light emitting portion 2, the third glass layer 1c is formed only on one of the first glass layer 1a side and the second glass layer 1b side. You may make it do.

  In addition, the material used for the temporary holding member 3 and the surface layer 3a in the said embodiment is an example, and if it is equivalent, it is possible to use another material. Moreover, in the said embodiment, although the manufacturing method of the luminous luminous body used as an evacuation guidance sign was shown, if it has a light emission part which consists of arbitrary figures and characters, other glass tiles for decoration etc. The present invention can also be applied to the production of luminous phosphors used for applications.
