Description

  The present invention relates to a method for manufacturing a luminous phosphor used for, for example, a white line on a road, a guidance line in a building, or a decorative pattern.

In general, white lines on roads are formed by applying paint to the road surface, but since the paint used for this type of white line does not have luminescent properties, it reduces visibility by car drivers and pedestrians at night. It was. Therefore, a granular phosphor is formed by crushing a mixture of a granular phosphorescent material and a glass material and pulverized, and this is fixed to the surface of a road white line, road tile, etc. Is known to emit a white line or the like at night (see, for example, Patent Document 1 or 2).
Japanese Patent No. 3580652 Japanese Patent No. 3580653

  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 in road white lines, etc. Since a granular phosphorescent material and a glass material are mixed and fired, if a large-grain phosphorescent material is used, the phosphorescent material cannot be uniformly disposed in the glass material during firing. For this reason, many crushed glass which does not contain a phosphorescent material is produced | generated, and when it was made to adhere to the surface of a white line etc., there existed a problem that light emission nonuniformity was easy to produce.

  The present invention has been made in view of the above problems, and the object of the present invention is to provide a luminous phosphor capable of efficiently forming a granular portion including a luminous portion even when a large-grain phosphorescent material is used. It is in providing the manufacturing method of.

  In order to achieve the above object, the present invention provides a method for producing a luminous phosphor, in which a light emitting part made of a phosphorescent material is formed inside a granular part made of a glass material, and temporarily holds the glass material on the surface. After forming the first glass layer that becomes a part of the granular portion on the surface of the member, the phosphorescent layer that becomes the light emitting portion is formed on the first glass layer of the temporary holding member, and the temporary holding member A second glass layer that is a part of the granular portion is formed on the first glass layer and the phosphorescent layer, and the first glass layer, the phosphorescent layer, and the second glass layer are peeled off from the temporary holding member. The granular part including the light emitting part is formed by grinding.

  Thereby, after the 1st glass layer used as a part of granular 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 By forming a second glass layer to be a part of the granular portion on the glass layer and the phosphorescent layer, peeling the first glass layer from the temporary holding member together with the phosphorescent layer and the second glass layer, and crushing Since the granular part and the light emitting part are formed, even when using a large grain phosphorescent material, the phosphorescent layer can be uniformly formed between the first and second glass layers on the temporary holding member, It becomes possible to arrange | position the grain of a phosphorescent material uniformly in the glass after baking.

  According to the present invention, even when a large-grain phosphorescent material is used, the particles of the phosphorescent material can be uniformly arranged in the glass after firing, so the amount of crushed glass not containing the phosphorescent material is reduced. Can do. Thereby, the granular part containing a light emission part can be formed efficiently, and the luminous luminous body excellent in the light emission performance can be manufactured easily.

  1 to 8 show an embodiment of the present invention. FIG. 1 is a perspective view of a luminous phosphor, FIGS. 2 to 6 are perspective views showing manufacturing steps thereof, and FIGS. 7 and 8 are manufacturing steps thereof. It is side surface sectional drawing which shows a process.

  This luminous phosphor comprises a transparent granular portion 1 and a light emitting portion 2 formed inside the granular portion 1, and is fixed to the surface of the white line B of the road A with an adhesive or the like as shown in FIG. Has been. The granular portion 1 is formed by pulverizing a glass material, and can transmit light from the light emitting portion 2 to the outside. The light emitting unit 2 is made of a granular phosphorescent material, and a known phosphor that absorbs external light and emits light in the dark is used as the phosphorescent material.

  Next, the manufacturing method of the said luminous luminous body is demonstrated. First, as shown in FIG. 2 and FIG. 7 (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 7 (b) by applying an adhesive (not shown) on top 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 of the granular portion 1 is formed on the substrate 3. Next, by applying an adhesive on the first glass layer 1a and adhering a granular phosphorescent material and a solvent mixture, the first glass layer as shown in FIGS. 4 and 7 (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. 7 (d). The second glass layer 1b which becomes a part of the granular 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 7 (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, the first glass layer 1a, the phosphorescent layer 2a and the second glass layer 1b are fired at a predetermined temperature (about 900 ° C.), so that the phosphorescent layer 2a has a large number of phosphorescent layers as shown in FIG. 8 (a). A plate-like glass 1c including the light-emitting portion 2 separated into particles of the material is formed, and the plate-like glass 1c is pulverized by a pulverizer to thereby obtain a number of granular portions including the light-emitting portion 2 as shown in FIG. 1 is formed. At that time, since the glass material has lower strength than the phosphorescent material, the glass material between the grains of the phosphorescent material (light emitting portion 2) is broken, and the glass material around the light emitting portion 2 is formed as the granular portion 1.

  Thus, according to this embodiment, after forming the 1st glass layer 1a used as a part of granular part 1 on the surface of the temporary holding member 3, the light emission part 2 and the 1st glass layer 1a are formed on the 1st glass layer 1a. And the second glass layer 1b which becomes a part of the granular portion 1 is formed on the first glass layer 1a and the luminous layer 2a, and the first glass layer 1a is converted to the luminous layer 2a. In addition, since the granular portion 1 and the light emitting portion 2 are formed by peeling and pulverizing from the temporary holding member 3 together with the second glass layer 1b, the temporary phosphorescent layer 2a is temporarily formed even when a large-grain phosphorescent material is used. On the holding member 3, it can form uniformly between the 1st and 2nd glass layers 1a and 1b, and the particle | grains of a phosphorescent material can be arrange | positioned uniformly in the plate-like glass 1c after baking. Thereby, since the generation amount of the crushed glass which does not contain a phosphorescent material can be reduced, the granular part 1 containing the light emission part 2 can be formed efficiently, and the luminous luminous body excellent in the light emission performance can be easily obtained. Can be manufactured.

  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, 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 fixed to the surface of the white line B of the road A was shown, the luminous property used for other uses, such as a guide line in a building and a pattern for decorations The present invention can also be applied to the manufacture of light emitters.
