As the result, the luminous pigments emitting phosphorescence can be arranged on the base disk 12 with preventing a luminous pigment not contributing to emitting phosphorescence. As the luminous part 13 is formed by being poured by the molding block 101, the thickness of the luminous part 13 is easily made larger by appropriately designing the molding block 101, and it is possible to make hard to generate position variations. The afterglow brightness of a luminous body 11 is easily increased because the afterglow brightness becomes high almost proportionally to the thickness of the luminous part 13.

Description

  The present invention relates to a method for producing a phosphor, and in particular, to produce a phosphor capable of suppressing phosphorescent pigments that do not contribute to emitting phosphorescence, and easily increasing the afterglow luminance, and making it difficult to cause variations in position of phosphorescent sites. It is about the method.

  Conventionally, as a means for causing a part of the surface of a member to emit light by phosphorescence, a phosphorescent layer containing a phosphorescent pigment is formed on the entire surface of the base sheet, and the phosphorescent layer is partially hidden by masking. Yes. Masking is performed by sticking an adhesive sheet on the surface of the base sheet or printing a paste for printing on the surface of the base sheet. In this case, since the phosphorescent layer concealed by masking is not used for emitting phosphorescence, there is a problem that the phosphorescent pigment contained in the concealed phosphorescent layer is wasted.

  Therefore, as a technique for partially forming a phosphorescent layer on the surface of a member, for example, a base sheet on which a phosphorescent pattern layer (phosphorescent layer) containing a phosphorescent pigment is formed is fed into a molding die and the molding die is closed. After that, a technique is known in which a molten resin is injected and filled into a cavity, and a phosphorescent pattern layer is adhered to the surface of the molded body simultaneously with molding (Patent Document 1). With the technique disclosed in Patent Document 1, since the phosphorescent layer can be partially formed without masking, it is possible to prevent the occurrence of phosphorescent pigments that do not contribute to emitting phosphorescence.

Japanese Patent No. 3527344

  However, in the technology disclosed in Patent Document 1, the phosphorescent pattern layer (phosphorescent layer) is made by a normal printing method such as an offset printing method, a gravure printing method, a screen printing method, etc. The thickness (dry thickness) was about 60 to 150 μm. Since the phosphorescent layer is formed on the surface of the molded body by adhering it in the molding die, the thickness of the phosphorescent layer on the surface of the molded body was also about 60 to 150 μm. The afterglow brightness of the phosphorescent layer tends to increase in proportion to the thickness of the phosphorescent layer, but it is difficult to increase the thickness of the phosphorescent layer by the printing method. For this reason, there is a problem that it is difficult to increase the afterglow luminance unless the type or blending amount of the phosphorescent pigment contained in the phosphorescent layer is changed.

  In the technique disclosed in Patent Document 1, the base sheet fed into the cavity moves in the cavity by the molten resin filled in the cavity, and is finally pressed against the inner surface of the cavity. The phosphorescent layer formed on the base sheet is adhered to the surface of the molten resin (molded body) at a position sandwiched between the molten resin and the inner surface of the cavity. Since the base sheet moves in the cavity during molding and bonding, there is a problem that the position of the phosphorescent layer with respect to the surface of the molded body tends to vary.

  The present invention has been made to solve the above-described problems, and can suppress phosphorescent pigments that do not contribute to emitting phosphorescence, and can easily increase the afterglow luminance and hardly cause variation in position of phosphorescent emitting portions. It aims at providing the manufacturing method of the phosphorescent material which can be performed.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the accompanying drawings. First, the phosphor 1 will be described with reference to FIG. FIG. 1 is a perspective view of the phosphor 1 in the first embodiment of the present invention, and FIG. 1B is an axial sectional view of the phosphor 1. As shown to Fig.1 (a) and FIG.1 (b), the luminous body 1 is a cap attached to the edge part of a steel pipe (pipe P) or a reinforcing bar (not shown), It is a protective device (safety article) that prevents the end from being exposed.

  As shown in FIG. 1A, the phosphorescent body 1 is positioned outside the inner cylinder 2, the inner cylinder 2 formed in a cylindrical shape, the substantially disk-shaped support body 3 provided at one end of the inner cylinder 2, and the inner cylinder 2. It mainly includes an outer cylinder 4 extending in the axial direction from the outer periphery of the support 3, a recess 3 a formed through substantially the center of the support 3, and a phosphorescent body 11 attached to the recess 3 a. The inner cylinder 2, the support body 3, the outer cylinder 4, and the like constituting the phosphorescent body 1 are integrally formed of a synthetic resin such as polyethylene.

  As shown in FIG.1 (b), the inner cylinder 2 is a site | part inserted by the pipe P, and the support body 3 is provided in the end. The support 3 is a part that is hit by a hammer or the like when the inner cylinder 2 is fitted into the pipe P, and an outer cylinder 4 whose tip abuts against the end of the pipe P is provided on the outer periphery. The contact portion 5 is a pin-shaped or annular portion located outside the inner wall portion 6 forming the recess 3 a and inside the inner cylinder 2, and has a bottomed cylindrical shape fitted into the inner cylinder 2. The bottom part of the reinforcing member 7 contacts.

  The reinforcing member 7 is a member made of synthetic resin such as nylon for reinforcing the inner cylinder 2, and a cylindrical hole 7a is formed at the center of the shaft. The hole 7a is a part into which a reinforcing bar (not shown) whose outer diameter is smaller than the outer diameter of the pipe P is inserted. Since the hole 7a is formed in the reinforcing member 7, the phosphor 1 can be attached to the end of the reinforcing bar by inserting a reinforcing bar (not shown) in the hole 7a instead of the pipe P. The inner wall portion 6 is a portion for holding the phosphor 11 in a space surrounded by the bottom surface of the reinforcing member 7 and the contact portion 5, and has an axial length (vertical length in FIG. 1 (b)). It is set smaller than the axial length of the contact portion 5.

  The phosphorescent body 11 includes a base portion 12 formed in a flat plate shape, and a phosphorescent portion 13 that is integrally formed so as to protrude from the front side of the base portion 12 (upper surface side, upper side in FIG. 1B). Yes. The area of the base part 12 is set to be larger than the area of the phosphorescent part 13 in the front view, and the base part 12 is located between the reinforcing member 7 and the inner wall part 6, and is located inside the inner wall part 6. The phosphorescent part 13 is located. Further, since the thickness of the base portion 12 (the vertical dimension in FIG. 1 (b)) is set to a value substantially equal to the difference between the axial lengths of the abutment portion 5 and the inner wall portion 6, it is located inside the recess 3a. The phosphorescent part 13 can be arrange | positioned. Furthermore, since the thickness of the phosphorescent portion 13 is set to be the same as or slightly smaller than the axial length of the inner wall portion 6, the phosphorescent portion 13 is arranged flush with the support 3 or slightly recessed. As a result, it is possible to prevent the phosphorescent portion 13 from being hit when the support 3 is hit with a hammer or the like while ensuring the visibility of the phosphorescent portion 13.

  Next, the phosphor 11 will be described with reference to FIG. FIG. 2A is a perspective view of the phosphorescent body 11, and FIG. 2B is a cross-sectional view of the mold 101, the base part 12, and the phosphorescent part 13 for explaining the manufacturing process of the phosphorescent body 11. As shown in FIG. 2A, the phosphorescent body 11 has a base portion 12 formed in a substantially circular shape when viewed from the front, and is stacked on the base portion 12 and protrudes toward the front side with respect to the base portion 12. And a substantially circular light storage portion 13 when viewed from the front. In the present embodiment, the base portion 12 and the phosphorescent portion 13 are made of silicone (made of silicone rubber), and a phosphorescent pigment is mixed with the silicone (polymer compound) constituting the phosphorescent portion 13.

As the phosphorescent pigment, one or a plurality of pigments having a function of sustaining light emission for a relatively long time in a dark place when irradiated with sunlight or artificial illumination light is used. For example, sulfur-based or oxide-based phosphorescent pigments can be used. Examples of sulfur-based phosphorescent pigments include calcium sulfide / bismuth and zinc sulfide / copper. Examples of the oxide-based phosphorescent pigment include compounds represented by M ¹ Al ₂ O ₄ , M ² Al ₁₄ O ₂₅ (where M ¹ and M ² are at least one of calcium, strontium, and barium). The thing which uses one or both as a mother crystal can be mentioned.

  The phosphorescent portion 13 is mixed with a colorant in addition to the phosphorescent pigment, and is prepared to have a color different from that of the base portion 12, thereby forming a predetermined pattern (circle in the present embodiment) that is visible under visible light. ing. Thereby, the visual interest under visible light can be improved also in the bright time (under irradiation of light of sunlight or artificial lighting) in which the phosphorescent unit 13 does not emit phosphorescence. Note that the pattern by the phosphorescent unit 13 is not limited to a geometric pattern such as a circle, and other graphic symbols, characters, patterns, and the like can be employed.

  Next, with reference to FIG.2 (b), the manufacturing method of the luminous body 11 is demonstrated. The phosphorescent body 11 is manufactured by pouring a polymer compound into the first concave surface 102 and the second concave surface 103 that are recessed in the molding die 101 and curing them. A cavity for molding the phosphorescent portion 13 is formed by the first concave surface 102, and a cavity for molding the base portion 12 is formed by the second concave surface 103. In the present embodiment, the mold 101 is made of FRP, and the phosphor 11 is manufactured by casting.

  In order to manufacture the phosphor 11, first, a phosphorescent pigment and a colorant are mixed with a polymer compound made of a condensation type one-component silicone (modified silicone) containing a modified silicone as a main component. Next, a liquid polymer compound in which the phosphorescent pigment and the colorant are mixed is poured into the first concave surface 102 of the mold 101 (phosphorescent part molding step). Before the polymer compound poured into the first concave surface 102 is completely cured, the modified silicone-based (condensation type one-component system) polymer compound not mixed with the phosphorescent pigment is used as the second concave surface of the mold 101. Pour into 103 (base part forming step). The polymer compound (phosphorescent part 13) poured into the second concave surface 103 is bonded to the base part 12 by the curing of the polymer compound (base part 12 and phosphorescent part 13) poured into the first concave surface 102 (adhesion). Process). After the polymer compound is cured, the base portion 12 and the phosphorescent portion 13 are removed from the mold 101 to obtain the phosphorescent body 11.

  According to the method for manufacturing the phosphorescent body 11 described above, the phosphorescent part 13 is mixed with the phosphorescent pigment, so that the phosphorescent pigment that emits phosphorescence can be arranged at a specific location on the front side of the base part 12. When the phosphorescent layer containing the phosphorescent pigment is partially concealed by masking, the phosphorescent pigment contained in the concealed phosphorescent layer is wasted, but according to this production method, the phosphorescent pigment that does not contribute to emitting phosphorescence is used. Can be suppressed. As a result, the amount of phosphorescent pigment required by the phosphorescent body 11 (the cost of the phosphorescent pigment) can be reduced.

  Moreover, since the phosphorescent part 13 is poured and shape | molded in the shaping | molding die 101, the shape of the luminous part 13 can be set suitably by designing the shaping | molding die 101 (1st concave surface 102) suitably. Further, the thickness of the phosphorescent portion 13 can be easily increased. The afterglow luminance of the phosphorescent unit 13 mixed with the phosphorescent pigment increases in proportion to the thickness of the phosphorescent unit 13 at a predetermined thickness where the excitation light does not pass through. Therefore, the afterglow luminance can be easily increased. it can.

  Further, the position of the phosphorescent portion 13 relative to the base portion 12 is determined by the positional relationship of the first concave surface 102 (cavity inner surface) and the second concave surface 103 of the mold 101, and the base portion 12 and the phosphorescent portion 13 are bonded to each other. Since it does not change when it is done, it is possible to make it difficult for the phosphor portion 13 to have a positional variation with respect to the base portion 12.

  Further, since the polymer compound constituting the base portion 12 is cured and the phosphorescent portion 13 is bonded at the same time, after the polymer compound constituting the base portion 12 is cured, the base portion 12 is bonded to the phosphorescent portion 13. Compared with the case where it does, the manufacturing process of the luminous body 11 can be shortened. In particular, since the curing of the base portion 12 and the phosphorescent portion 13 and the adhesion between the phosphorescent portion 13 and the base portion 12 are performed at the same time, it is affected by the wettability of the polymer compound (the phosphorescent portion 13) after curing. In addition, the bonding strength between the base portion 12 and the phosphorescent portion 13 can be ensured.

  Further, since the phosphor 11 is manufactured by cast molding, the manufacturing cost of the molding die 101 can be suppressed, and small lot production can be realized. Furthermore, since the phosphorescent pigment is mixed with the liquid polymer compound poured into the mold 101, the blending ratio of the phosphorescent pigment with respect to the phosphorescent portion 13 can be increased. As a result, the afterglow brightness of the light storage unit 13 can be improved.

  Here, the phosphorescent pigment is mixed at a ratio of 3 to 70 parts by mass, preferably 30 to 70 parts by mass with respect to 100 parts by mass of the total mass of the polymer compound and the phosphorescent pigment poured into the first concave surface 102. Thereby, the afterglow brightness | luminance of the phosphorescence part 13 is securable, ensuring the fluidity | liquidity of a liquid polymer compound. In addition, the afterglow brightness | luminance of the phosphorescence part 13 tends to fall as the mixture of the phosphorescent pigment decreases, and when it is less than 30 parts by mass, the afterglow brightness of the phosphorescence part 13 is influenced by the color of the base part 12. May be significantly lower. Moreover, when there are more compounding of a luminous pigment than 70 mass parts, although depending on the kind of high molecular compound and the particle size of a luminous pigment, fluidity | liquidity will fall and the tendency for cast molding to become difficult will be seen.

  Returning to FIG. 1, a method for manufacturing the phosphor 1 will be described. Before inserting the reinforcing member 7 into the inner cylinder 2 of the phosphorescent body 1, the phosphorescent body 11 is arranged from the back side (the lower side of FIG. 1B) of the inner cylinder 2 (arrangement step). In the arranged phosphorescent body 11, the phosphorescent portion 13 is located inside the inner wall portion 6, and the base portion 12 is located on the tip side of the inner wall portion 6. Next, the reinforcing member 7 is inserted into the inner cylinder 2 until the bottom surface of the reinforcing member 7 contacts the tip of the contact portion 5. Thereby, the luminous body 11 is held between the reinforcing member 7 and the inner wall portion 6.

  Since the area of the base 12 in the front view of the phosphorescent body 11 is set to be larger than the area of the phosphorescent section 13 in the front view, the tip of the inner wall 6 (see FIG. 1B) is placed on the top surface of the base 12. Can be located. As a result, since the phosphor 12 is prevented from being detached from the recess 3 a by the base portion 12, the phosphor 11 can be easily held between the support 3 and the reinforcing member 7. As a result, by attaching the phosphorescent body 1 to the tip of the pipe P or the reinforcing bar (not shown), the end of the pipe P or the reinforcing bar can be prevented from being exposed by the support body 3 and the outer cylinder 4, and the phosphorescent portion 13 phosphorescence can alert you at night.

  Moreover, since the phosphorescent part 13 is arrange | positioned in the recessed part 3a penetrated and formed in the support body 3, the phosphorescent part 13 according to the uses and purposes, such as guidance, a sign, alerting, etc., can be arrange | positioned in the support body 3. As a result, the versatility of the phosphor 11 can be improved and the application range can be expanded according to the shape of the support 3 and the like.

  Next, a second embodiment will be described with reference to FIG. In the first embodiment, the case where the base portion 12 and the phosphorescent portion 13 are in close contact with each other has been described. On the other hand, 2nd Embodiment demonstrates the case where the reflection layer 24 is interposed between the base part 22 and the luminous part 23. FIG. 3A is a perspective view of the phosphor 21 in the second embodiment, and FIG. 3B is a cross-sectional view of the mold 201, the base 22 and the phosphor 23 for explaining the manufacturing process of the phosphor 21. FIG. It is.

  As shown in FIG. 3A, the phosphorescent body 21 is stacked on the base portion 22 and on the front side with respect to the base portion 22 while being transparently formed in a substantially rectangular shape when viewed from the front. The phosphorescent part 23 which protruded and formed the geometric pattern is provided, and the reflection layer 24 interposed between the phosphorescent part 23 and the base | substrate part 22 is provided. In the present embodiment, the base portion 22 and the phosphorescent portion 23 are made of an epoxy resin, and a phosphorescent pigment and a colorant are mixed in the epoxy resin (polymer compound) constituting the phosphorescent portion 23. Since the phosphorescent pigment is the same as that described in the first embodiment, the description thereof is omitted.

  The base portion 22 includes a base portion 22a formed in a substantially flat plate shape, and a protruding portion 22b in which the center of the base portion 22a protrudes. Moreover, the light storage part 23 is provided with the 1st light storage part 23a and the 2nd light storage part 23b which are divided | segmented and arrange | positioned around the protruding part 22b. In the present embodiment, the protruding portion 22b is formed in a substantially circular shape when viewed from the front, and the first light storage portion 23a and the second light storage portion 23b are formed in a substantially C shape when viewed from the front. The first phosphorescent unit 23a and the second phosphorescent unit 23b are mixed with different types of phosphorescent pigments and configured to emit phosphorescent light of different colors. In addition, the height of the protruding portion 22b with respect to the base portion 22a is set to the same value as the height of the first light storage portion 23a and the second light storage portion 23b with respect to the base portion 22a.

  Next, with reference to FIG.3 (b), the manufacturing method of the luminous body 21 is demonstrated. The phosphorescent body 21 is manufactured by pouring a polymer compound into the second concave surface 203 and the two first concave surfaces 202 provided in the mold 201 and curing them. A cavity for molding the phosphorescent part 23 (first phosphorescent part 23a and second phosphorescent part 23b) and the reflective layer 24 is formed by the two first concave surfaces 202, and the base part 22 is molded by the second concave surface 203. A cavity is formed. In the present embodiment, the mold 201 is made of silicone, and the phosphor 21 is manufactured by casting.

  In order to manufacture the phosphor 21, first, a phosphorescent pigment and a colorant are mixed with an epoxy resin (polymer compound). Two types of polymer compounds in which different types of phosphorescent pigments are mixed are prepared. Next, the polymer compound in which one phosphorescent pigment and the colorant were mixed was poured into one first concave surface 202 (right side of FIG. 3B) of the mold 201, and the other phosphorescent pigment and the colorant were mixed. The polymer compound is poured into the other first concave surface 202 (left side of FIG. 3B) (phosphorescent part forming step). The polymer compound that forms the reflective layer 24 is applied to the place where the polymer compound poured into the first concave surface 202 has hardened and contracted (the place where the polymer compound is recessed and lowered with respect to the boundary with the second concave surface 203). (Reflective layer placement step). In the present embodiment, the reflective layer 24 (white reflective layer) is formed of a white paint in which a titanium resin powder is mixed with a polyester-based resin or the like.

  After the white paint is cured, a transparent epoxy resin (polymer compound) is poured into the second concave surface 203 of the mold 201 (base part molding step). The base portion 22 is bonded to the reflective layer 24 by the curing of the polymer compound poured into the second concave surface 203 (adhesion step). After the polymer compound is cured, the base portion 22, the phosphorescent portion 23 and the reflective layer 24 are removed from the mold 201 to obtain the phosphorescent body 21.

  According to the method for manufacturing the phosphorescent body 21 described above, the reflective layer 24 is disposed on the back surface of the phosphorescent portion 23, and the reflective layer 24 is sandwiched between the phosphorescent portion 23 and the base portion 22. As a result, phosphorescence due to the phosphorescent pigment is reflected to the front side (opposite side of the base portion 22), so that the afterglow luminance of the phosphorescent portion 23 can be improved in addition to the effects obtained in the first embodiment.

  In addition, since the polymer compound poured into the first concave surface 202 is cured and contracted (in the first concave surface 202), the polymer compound (white paint) that forms the reflective layer 24 is applied. It is possible to make it difficult for the white paint to protrude around 23. As a result, it is possible to prevent the appearance of the phosphor 21 from being deteriorated due to the white paint (reflective layer) that protrudes around the phosphorescent unit 23.

  In addition, since the base part 22 is formed by the epoxy resin having a weak water repellency compared with the silicone type, the phosphorescent body 21 can easily form an adhesive layer by applying an adhesive to the back surface of the base part 22. it can. Thereby, the application example of the attachment means of the luminous body 21 with respect to a target object (not shown) can be increased, and the application range of the luminous body 21 can be expanded.

  Moreover, since the phosphorescence part 23 (the 1st phosphorescence part 23a and the 2nd phosphorescence part 23b) is divided and formed in the several places (2 places in this Embodiment) of the front surface of the base | substrate part 22, the design property of the phosphorescence body 21 is formed. Can be improved. The phosphorescent portion 23 can be formed at an arbitrary position by appropriately designing the mold 201. Furthermore, since the 1st luminous part 23a and the 2nd luminous part 23b are set so that a mutually different color phosphorescence may be emitted, the design property of the luminous body 21 can further be improved.

  In the present embodiment, the case where the reflective layer 24 is formed by applying a white paint has been described. However, the present invention is not necessarily limited to this, and as in the case where the base portion 22 and the phosphorescent portion 23 are formed, a high It is naturally possible to form the reflective layer 24 by pouring molecular compounds. In addition, it is naturally possible to form the reflective layer 24 by arranging and sandwiching a white sheet (white formed material) prepared in advance between the first phosphorescent portion 23a and the second phosphorescent portion 23b and the base portion 22. is there.

  Next, a third embodiment will be described with reference to FIG. In 1st Embodiment and 2nd Embodiment, the case where the base parts 12 and 22 made from a high molecular compound were formed by mold shaping was demonstrated. On the other hand, in 3rd Embodiment, the case where the separately prepared base part 32 is adhere | attached on the luminous part 33 and the luminous body 31 is manufactured is demonstrated. FIG. 4A is a perspective view of the phosphorescent body 31 according to the third embodiment, and FIG. 4B is a cross-sectional view of the mold 301 and the phosphorescent portion 33 for explaining the manufacturing process of the phosphorescent body 31.

  As shown in FIG. 4A, the phosphorescent body 31 has a base portion 32 formed in a substantially rectangular shape when viewed from the front, and is stacked on the base portion 32 and protrudes to the front side with respect to the base portion 32. And a phosphorescent unit 33 in which a graphic symbol (arrow) is formed. In the present embodiment, the base portion 32 is made of a flexible cloth, and a phosphorescent pigment and a colorant are mixed with the silicone rubber (polymer compound) constituting the phosphorescent portion 33. Since the phosphorescent pigment is the same as that described in the first embodiment, the description thereof is omitted.

  Next, with reference to FIG.4 (b), the manufacturing method of the phosphor 31 is demonstrated. The phosphorescent body 31 is manufactured by pouring a polymer compound into a concave surface 302 provided in the mold 301 and curing it to form the phosphorescent portion 33 and bonding the base portion 32 to the phosphorescent portion 33. A cavity for molding the phosphorescent portion 33 is formed by the concave surface 302. In the present embodiment, the forming die 301 is made of an aluminum alloy (made of metal), and the phosphor 31 is manufactured by casting.

  In order to manufacture the phosphorescent body 31, first, a phosphorescent pigment and a colorant are mixed with silicone (polymer compound). Next, a liquid polymer compound in which the phosphorescent pigment and the colorant are mixed is poured into the concave surface 302 of the mold 301 (phosphorescent part molding step). When the polymer compound poured into the concave surface 302 is cured and shrunk (where it is dented and becomes lower than the height of the upper surface of the mold 301), a transparent polymer compound (in this embodiment, phosphorescent light is stored). (Silicone without pigments and colorants).

  Before the transparent polymer compound poured into the concave surface 302 is cured, the base portion 32 (made of cloth) is placed on the upper surface of the mold 301 to bring the polymer compound in the concave surface 302 into contact with the base portion 32. Silicone (liquid polymer compound) penetrates between the fibers of the base portion 32. By the curing of the polymer compound, the phosphorescent portion 33 and the base portion 32 are bonded mainly by the anchor effect (bonding step). After the phosphorescent part 33 and the base part 32 are bonded, the phosphorescent part 33 is removed from the mold 301 to obtain the phosphor 31.

  According to the method for manufacturing the phosphorescent body 31 described above, the phosphorescent part 33 is bonded to the base part 32 by curing of the polymer compound poured into the mold 301 (concave surface 302). By curing the polymer compound constituting the phosphorescent part 33 and bonding the base part 32 simultaneously, the polymer compound constituting the phosphorescent part 33 is cured, and then the phosphorescent part 33 is adhered to the base part 32. Compared with the case, the manufacturing process of the phosphor 31 can be shortened.

  In addition, after the shrinkage of the polymer compound mixed with the phosphorescent pigment, a transparent polymer compound is poured into the concave surface 302 and the polymer compound in the concave surface 302 is brought into contact with the base portion 32. The inner polymer compound can be reliably brought into contact. In addition, since the shrinkage (so-called sink) of the polymer compound in the concave surface 302 can be compensated, it is possible to prevent the bonding strength between the phosphorescent portion 33 and the base portion 32 from being reduced due to the shrinkage of the polymer compound in the concave surface 302. . Further, even when the polymer compound protrudes around the phosphorescent portion 33 and hardens, the appearance of the phosphor 31 can be prevented from deteriorating because the polymer compound is transparent.

  In addition, since the cloth base part 32 is fixed to the back surface of the base part 33 and the size of the base part 32 in the front view is set larger than that of the phosphorescent part 33 in the front view, the cloth base part 32 is made of cloth on the surface of clothes or the like (target object). The base portion 32 can be sewn. In addition, it is also possible to affix the base | substrate part 32 to the surface of clothes etc. (target object) by providing the back surface of the base | substrate part 32 with the heat bonding layer fuse | melted with heat, such as an iron.

  The base portion 32 is formed of a flexible member (made of cloth), and the phosphorescent portion 33 is formed of a silicone polymer compound. The phosphorescent portion 33 is bonded to the base portion 32 by the curing of the silicone polymer compound. Since the silicone polymer compound penetrates between the fibers of the base portion 32 (cloth) and is cured, the phosphorescent portion 33 is firmly bonded to the base portion 32 by the anchor effect. Further, since the silicone polymer compound becomes rubber after curing, the flexibility of the base portion 32 is also maintained. As a result, the flexibility of the base part 32 to which the phosphorescent part 33 is bonded can be maintained.

  Note that the adhesion mechanism between the silicone polymer compound and the base portion 32 is not limited to the anchor effect. Depending on the type of the base portion 32, it is naturally possible to bond the surface of the base portion 32 and the phosphorescent portion 33 by a chemical reaction.

  The present invention has been described above based on the embodiments. However, the present invention is not limited to the above embodiments, and various improvements and modifications can be made without departing from the spirit of the present invention. It can be easily guessed. For example, the shapes and sizes of the base parts 12, 22, 32 and the phosphorescent parts 13, 23, 33 are appropriately designed according to the purpose of the phosphorescent bodies 11, 21, 31.

  In the first embodiment, the case where the phosphorescent body 11 is molded using a polymer compound made of condensation type one-component silicone (modified silicone) is described. However, other polymer compounds may be used. Of course it is possible. Examples of other polymer compounds include addition type silicones, polyurethane resins, epoxy resins, polyester resins, acrylic resins, and ultraviolet curable resins. In addition, the polymer compound is not limited to a one-component (one-component) resin, and it is naturally possible to use a multi-component resin such as a two-component resin.

  In consideration of the material and shape of the phosphor 11 and the durability of the mold 101, the material of the mold 101 can be set as appropriate. In addition, as in the first embodiment, other polymer compounds can naturally be employed for the polymer compounds in the second embodiment and the third embodiment. Note that the first embodiment and the second embodiment may be vacuum casting in which casting is performed under reduced pressure.

  In the said 1st Embodiment and 2nd Embodiment, although the case where the phosphorescent bodies 11 and 21 were manufactured by cast molding was demonstrated, it is not necessarily restricted to this and employ | adopting another shaping | molding means. Of course it is possible. Examples of other molding means include injection molding, hollow molding, and compression molding. When the phosphors 11 and 21 are manufactured by injection molding, hollow molding, or compression molding, metal molds 101 and 201 are used and combined with another mold to form a cavity.

  When manufacturing phosphorescent bodies 11 and 21 by injection molding or hollow molding, a master batch of polymer compound (synthetic resin, synthetic rubber, etc.) and phosphorescent pigment (about half the target value to be finally kneaded) are mixed Etc., and knead using an extruder or the like while heating to a predetermined temperature. Next, the obtained kneaded product and the phosphorescent pigment (remaining amount to be finally kneaded) are mixed using a mixer or the like, and kneaded using an extruder or the like while being heated to a predetermined temperature.

  If the phosphorescent pigment is kneaded at once without dividing into multiple times, the fluidity when kneading the master batch of the polymer compound and the phosphorescent pigment is lowered, and the dispersibility of the phosphorescent pigment is lowered. There is a tendency to In contrast, the fluidity can be improved by kneading the phosphorescent pigment in a plurality of times, and the dispersibility of the phosphorescent pigment can be improved. As a result, it is possible to prevent the phosphorescent pigment from being unevenly distributed in a part of the phosphorescent portions 13 and 23. Then, the polymer compound heated to the softening temperature is poured into a mold by applying an injection pressure, filled into a cavity, and molded.

  When manufacturing phosphorescent body by compression molding, mix powdery (granular) polymer compound (mainly thermosetting resin) and phosphorescent pigment, pour them into the mold cavity, then heat Then, it is cured and molded by applying pressure.

  In the said 1st Embodiment, although the phosphor 1 as a protective device (safety goods) which prevents that the end part of the pipe P or a reinforcing bar becomes exposed was demonstrated, it is not necessarily restricted to this, The support body 3 Of course, it is possible to use the phosphorescent body as a guide plate, a sign, or the like by appropriately designing the shape and size of the lamp.

  Further, since the phosphors 11, 21, 31 described in the above embodiment can be formed into arbitrary shapes, the phosphors 11, 21, 31 are made of toys such as mascots, pendants, key holders, accessories such as daily goods, name tags, etc. Of course, building members such as flooring and curbs, and civil engineering members are possible.

  In the said embodiment, although the case where the one phosphorescence part 13,23,33 was arrange | positioned on the surface of the base | substrate parts 12,22,32 was demonstrated, it is not necessarily restricted to this, and physically separated 2 It is naturally possible to provide the above phosphorescent part on the surface of the base part.

  In the said 1st Embodiment, although the case where the support body 3 was formed in plate shape (planar shape) was demonstrated, it is not necessarily restricted to this, A lump shape (three-dimensional shape) according to the form of a luminous body It is naturally possible to form.

  Moreover, although the case where the concave portion 3a is formed through the support body 3 has been described, the present invention is not necessarily limited to this. When the support body is formed in a lump shape, the concave portion is formed in a depression shape on the surface of the support body. Of course, it is possible to make it possible to attach a phosphorescent body to the recess.

  In the said 1st Embodiment and 2nd Embodiment, about the case where the phosphorescence body 11 and 21 is manufactured by joining (adhering) the phosphorescence part 13 and 23 and the base | substrate parts 12 and 22 with one shaping | molding die 101,201. explained. However, the present invention is not necessarily limited to this, and it is possible to make the mold for molding the phosphorescent parts 13 and 23 different from the mold for joining (adhering) the phosphorescent parts 13 and 23 to the base parts 12 and 22. It is.

  In this case, first, the phosphorescent portions 13 and 23 are molded by one molding die (not shown). In this case, various molding methods such as cast molding, injection molding, and compression molding can be employed. Thereafter, the molded phosphorescent portions 13 and 23 are arranged (temporarily fixed) on the cavity inner surface of another mold (not shown) (phosphorescent portion arranging step). Next, a polymer compound is poured into another mold (cavity) in which the phosphorescent portions 13 and 23 are arranged, and the phosphorescent portions 13 and 23 are bonded to the base portions 12 and 22 while the base portions 12 and 22 are molded. (Phosphorescent part adhesion process). In this case, various molding methods such as cast molding, injection molding, compression molding, and the like can be employed for molding the base portions 12 and 22. As described above, the first embodiment also applies when the mold for molding the phosphorescent parts 13 and 23 is different from the mold for joining (adhering) the phosphorescent parts 13 and 23 and the base parts 12 and 22. Or the effect acquired by 2nd Embodiment is realizable.

  In addition, the phosphorescent portions 13 and 23 are not molded by cast molding, injection molding, compression molding, or the like, but a phosphorescent material such as a phosphorescent sheet containing a phosphorescent pigment or a ceramic plate (a substrate made of an inorganic material) having a property of emitting phosphorescence ( Naturally, it is possible to prepare and use a “light-storing member” hereinafter in a predetermined outer shape. In that case, first, a phosphorescent member (phosphorescent portion) prepared in a predetermined shape is arranged on the inner surface of the cavity of the mold (phosphorescent portion arranging step). Next, the polymer compound is poured into a mold (in the cavity) in which the phosphorescent member (phosphorescent part) is arranged, and the phosphorescent part is bonded to the base part while the base part is molded (phosphorescent part bonding step). In this case as well, various molding methods such as cast molding, injection molding, compression molding, and the like can be adopted for molding the base portion, and the effects obtained in the first embodiment or the second embodiment can be realized.

  It is naturally possible to provide an adhesive layer on the back surface of the phosphorescent member (phosphorescent portion). As the adhesive layer, a heat-sensitive or pressure-sensitive polymer compound suitable for the polymer compound material is appropriately selected. It is naturally possible to provide a reflective layer (white reflective layer) on the back surface of the phosphorescent member (phosphorescent portion). As the reflection layer, a coating layer formed on the back surface of the phosphorescent member (phosphorescent portion) by applying a white paint, or a white sheet disposed on the back surface of the phosphorescent member (phosphorescent portion) can be used. It is naturally possible to provide an adhesive layer on the white sheet (reflective layer).

  In the third embodiment, the case where the base portion 32 is made of cloth has been described. However, the present invention is not necessarily limited to this, and other materials and members can naturally be used. Other materials and components include, for example, sheets and wallpaper made of paper or synthetic resin; leather (natural leather, artificial leather); synthetic resin, glass, metal plate; metal or synthetic resin mesh Tile (made of inorganic material) and the like. Of course, a retroreflective plate made of synthetic resin or the like can be used as the base portion 32. Since various materials and members can be employed as the base portion 32, the usage of the phosphorescent body 31 can be expanded.

  In addition, when a thing having meshes (gap between fibers or wires) such as paper, leather, etc. (fiber aggregate) or nets is adopted as the base portion 32, the polymer compound is filled in the mesh. The anchor effect is obtained by curing. Silicone (silicone rubber) is a difficult-to-adhere material, but the adhesive strength between the base portion 32 and the phosphorescent portion 33 can be improved by utilizing the anchor effect.

  In the third embodiment, the case where the base portion 32 is bonded simultaneously with the curing of the phosphorescent portion 33 has been described. However, the present invention is not necessarily limited thereto, and the phosphorescent portion 33 is molded (cured) and then bonded. It is naturally possible to bond the phosphorescent part 33 to the base part 32 using an agent or the like. In that case, in order to improve the adhesive strength between the base part 32 and the phosphorescent part 33, the base part 32 and the phosphorescent part 33 can be subjected to a primer treatment.

  Moreover, it is naturally possible to provide the reflection layer 24 described in the second embodiment on the phosphors 11 and 31 described in the first and third embodiments. By providing the reflective layer 24 on the back surfaces of the light storage units 13 and 33, the afterglow luminance of the light storage units 13 and 33 can be improved. Instead of providing the reflection layer 24, it is naturally possible to make the base portions 12 and 32 white and reflect the phosphorescence of the phosphorescent portions 13 and 33 by the base portions 12 and 32.

  The thickness of the phosphorescent portions 13, 23 and 33 (including the phosphorescent member) is 0.5 mm to 10 cm, depending on the particle size of the phosphorescent pigment and the color (background color) and size of the base portions 12, 22, and 32. Are preferably used. This is to make the afterglow luminance of the phosphorescent units 13, 23, and 33 (including the phosphorescent member) less susceptible to the colors of the base units 12, 22, and 32.

  In the present embodiment, the case where the phosphorescent units 13, 23, and 33 contain sulfur-based or oxide-based phosphorescent pigments has been described. However, the present invention is not necessarily limited to this, and absorbs energy of excitation light from the outside. Thus, it is naturally possible to employ other phosphorescent pigments that emit phosphorescence. Moreover, although the case where the luminous parts 13, 23, and 33 contain a colorant has been described, the colorant is not necessarily required.

22b Protruding part (base part)
13, 23, 33 phosphorescent part 23a first phosphorescent part (phosphorescent part)
23b Second phosphorescent part (phosphorescent part)
24 Reflective layer 101, 201, 301 Mold 102, 202 First concave surface (inner surface of cavity)

  The present invention relates to a method for producing a phosphor, and in particular, to produce a phosphor capable of suppressing phosphorescent pigments that do not contribute to emitting phosphorescence, and easily increasing the afterglow luminance, and making it difficult to cause variations in position of phosphorescent sites. It is about the method.

  Conventionally, as a means for causing a part of the surface of a member to emit light by phosphorescence, a phosphorescent layer containing a phosphorescent pigment is formed on the entire surface of the base sheet, and the phosphorescent layer is partially hidden by masking. Yes. Masking is performed by sticking an adhesive sheet on the surface of the base sheet or printing a paste for printing on the surface of the base sheet. In this case, since the phosphorescent layer concealed by masking is not used for emitting phosphorescence, there is a problem that the phosphorescent pigment contained in the concealed phosphorescent layer is wasted.

  Therefore, as a technique for partially forming a phosphorescent layer on the surface of a member, for example, a base sheet on which a phosphorescent pattern layer (phosphorescent layer) containing a phosphorescent pigment is formed is fed into a molding die and the molding die is closed. After that, a technique is known in which a molten resin is injected and filled into a cavity, and a phosphorescent pattern layer is adhered to the surface of the molded body simultaneously with molding (Patent Document 1). With the technique disclosed in Patent Document 1, since the phosphorescent layer can be partially formed without masking, it is possible to prevent the occurrence of phosphorescent pigments that do not contribute to emitting phosphorescence.

Japanese Patent No. 3527344

  However, in the technology disclosed in Patent Document 1, the phosphorescent pattern layer (phosphorescent layer) is made by a normal printing method such as an offset printing method, a gravure printing method, a screen printing method, etc. The thickness (dry thickness) was about 60 to 150 μm. Since the phosphorescent layer is formed on the surface of the molded body by adhering it in the molding die, the thickness of the phosphorescent layer on the surface of the molded body was also about 60 to 150 μm. The afterglow brightness of the phosphorescent layer tends to increase in proportion to the thickness of the phosphorescent layer, but it is difficult to increase the thickness of the phosphorescent layer by the printing method. For this reason, there is a problem that it is difficult to increase the afterglow luminance unless the type or blending amount of the phosphorescent pigment contained in the phosphorescent layer is changed.

  In the technique disclosed in Patent Document 1, the base sheet fed into the cavity moves in the cavity by the molten resin filled in the cavity, and is finally pressed against the inner surface of the cavity. The phosphorescent layer formed on the base sheet is adhered to the surface of the molten resin (molded body) at a position sandwiched between the molten resin and the inner surface of the cavity. Since the base sheet moves in the cavity during molding and bonding, there is a problem that the position of the phosphorescent layer with respect to the surface of the molded body tends to vary.

  The present invention has been made to solve the above-described problems, and can suppress phosphorescent pigments that do not contribute to emitting phosphorescence, and can easily increase the afterglow luminance and hardly cause variation in position of phosphorescent emitting portions. It aims at providing the manufacturing method of the phosphorescent material which can be performed.

It is set smaller than the axial length of the contact portion 5.

  The phosphorescent body 11 includes a base portion 12 formed in a flat plate shape, and a phosphorescent portion 13 that is integrally formed so as to protrude from the front side of the base portion 12 (upper surface side, upper side in FIG. 1B). Yes. The area of the base part 12 is set to be larger than the area of the phosphorescent part 13 in the front view, and the base part 12 is located between the reinforcing member 7 and the inner wall part 6, and is located inside the inner wall part 6. The phosphorescent part 13 is located. Further, since the thickness of the base portion 12 (the vertical dimension in FIG. 1 (b)) is set to a value substantially equal to the difference between the axial lengths of the abutment portion 5 and the inner wall portion 6, it is located inside the recess 3a. The phosphorescent part 13 can be arrange | positioned. Furthermore, since the thickness of the phosphorescent portion 13 is set to be the same as or slightly smaller than the axial length of the inner wall portion 6, the phosphorescent portion 13 is arranged flush with the support 3 or slightly recessed. As a result, it is possible to prevent the phosphorescent portion 13 from being hit when the support 3 is hit with a hammer or the like while ensuring the visibility of the phosphorescent portion 13.

  Next, the phosphor 11 will be described with reference to FIG. FIG. 2A is a perspective view of the phosphorescent body 11, and FIG. 2B is a cross-sectional view of the mold 101, the base part 12, and the phosphorescent part 13 for explaining the manufacturing process of the phosphorescent body 11. As shown in FIG. 2A, the phosphorescent body 11 has a base portion 12 formed in a substantially circular shape when viewed from the front, and is stacked on the base portion 12 and protrudes toward the front side with respect to the base portion 12. And a substantially circular light storage portion 13 when viewed from the front. In the present embodiment, the base portion 12 and the phosphorescent portion 13 are made of silicone (made of silicone rubber), and a phosphorescent pigment is mixed with the silicone (polymer compound) constituting the phosphorescent portion 13.

As the phosphorescent pigment, one or a plurality of pigments having a function of sustaining light emission for a relatively long time in a dark place when irradiated with sunlight or artificial illumination light is used. For example, sulfur-based or oxide-based phosphorescent pigments can be used. Examples of sulfur-based phosphorescent pigments include calcium sulfide / bismuth and zinc sulfide / copper. Examples of the oxide-based phosphorescent pigment include compounds represented by M ¹ Al ₂ O ₄ , M ² Al ₁₄ O ₂₅ (where M ¹ and M ² are at least one of calcium, strontium, and barium). The thing which uses one or both as a mother crystal can be mentioned.

  The phosphorescent portion 13 is mixed with a colorant in addition to the phosphorescent pigment, and is prepared to have a color different from that of the base portion 12, thereby forming a predetermined pattern (circle in the present embodiment) that is visible under visible light. ing. Thereby, the visual interest under visible light can be improved also in the bright time (under irradiation of light of sunlight or artificial lighting) in which the phosphorescent unit 13 does not emit phosphorescence. Note that the pattern by the phosphorescent unit 13 is not limited to a geometric pattern such as a circle, and other graphic symbols, characters, patterns, and the like can be employed.

  Next, with reference to FIG.2 (b), the manufacturing method of the luminous body 11 is demonstrated. The phosphorescent body 11 is manufactured by pouring a polymer compound into the first concave surface 102 and the second concave surface 103 that are recessed in the molding die 101 and curing them. A cavity for molding the phosphorescent portion 13 is formed by the first concave surface 102, and a cavity for molding the base portion 12 is formed by the second concave surface 103. In the present embodiment, the mold 101 is made of FRP, and the phosphor 11 is manufactured by casting.

  In order to manufacture the phosphor 11, first, a phosphorescent pigment and a colorant are mixed with a polymer compound made of a condensation type one-component silicone (modified silicone) containing a modified silicone as a main component. Next, a liquid polymer compound in which the phosphorescent pigment and the colorant are mixed is poured into the first concave surface 102 of the mold 101 (phosphorescent part molding step). Before the polymer compound poured into the first concave surface 102 is completely cured, the modified silicone-based (condensation type one-component system) polymer compound not mixed with the phosphorescent pigment is used as the second concave surface of the mold 101. Pour into 103 (base part forming step). The polymer compound (phosphorescent part 13) poured into the second concave surface 103 is bonded to the base part 12 by the curing of the polymer compound (base part 12 and phosphorescent part 13) poured into the first concave surface 102 (adhesion). Process). After the polymer compound is cured, the base portion 12 and the phosphorescent portion 13 are removed from the mold 101 to obtain the phosphorescent body 11.

  According to the method for manufacturing the phosphorescent body 11 described above, the phosphorescent part 13 is mixed with the phosphorescent pigment, so that the phosphorescent pigment that emits phosphorescence can be arranged at a specific location on the front side of the base part 12. When the phosphorescent layer containing the phosphorescent pigment is partially concealed by masking, the phosphorescent pigment contained in the concealed phosphorescent layer is wasted, but according to this production method, the phosphorescent pigment that does not contribute to emitting phosphorescence is used. Can be suppressed. As a result, the amount of phosphorescent pigment required by the phosphorescent body 11 (the cost of the phosphorescent pigment) can be reduced.

  Moreover, since the phosphorescent part 13 is poured and shape | molded in the shaping | molding die 101, the shape of the luminous part 13 can be set suitably by designing the shaping | molding die 101 (1st concave surface 102) suitably. Further, the thickness of the phosphorescent portion 13 can be easily increased. The afterglow luminance of the phosphorescent unit 13 mixed with the phosphorescent pigment increases in proportion to the thickness of the phosphorescent unit 13 at a predetermined thickness where the excitation light does not pass through. Therefore, the afterglow luminance can be easily increased. it can.

  Further, the position of the phosphorescent portion 13 relative to the base portion 12 is determined by the positional relationship of the first concave surface 102 (cavity inner surface) and the second concave surface 103 of the mold 101, and the base portion 12 and the phosphorescent portion 13 are bonded to each other. Since it does not change when it is done, it is possible to make it difficult for the phosphor portion 13 to have a positional variation with respect to the base portion 12.

  Further, since the polymer compound constituting the base portion 12 is cured and the phosphorescent portion 13 is bonded at the same time, after the polymer compound constituting the base portion 12 is cured, the base portion 12 is bonded to the phosphorescent portion 13. Compared with the case where it does, the manufacturing process of the luminous body 11 can be shortened. In particular, since the curing of the base portion 12 and the phosphorescent portion 13 and the adhesion between the phosphorescent portion 13 and the base portion 12 are performed at the same time, it is affected by the wettability of the polymer compound (the phosphorescent portion 13) after curing. In addition, the bonding strength between the base portion 12 and the phosphorescent portion 13 can be ensured.

  Further, since the phosphor 11 is manufactured by cast molding, the manufacturing cost of the molding die 101 can be suppressed, and small lot production can be realized. Furthermore, since the phosphorescent pigment is mixed with the liquid polymer compound poured into the mold 101, the blending ratio of the phosphorescent pigment with respect to the phosphorescent portion 13 can be increased. As a result, the afterglow brightness of the light storage unit 13 can be improved.

  Here, the phosphorescent pigment is mixed at a ratio of 3 to 70 parts by mass, preferably 30 to 70 parts by mass with respect to 100 parts by mass of the total mass of the polymer compound and the phosphorescent pigment poured into the first concave surface 102. Thereby, the afterglow brightness | luminance of the phosphorescence part 13 is securable, ensuring the fluidity | liquidity of a liquid polymer compound. In addition, the afterglow brightness | luminance of the phosphorescence part 13 tends to fall as the mixture of the phosphorescent pigment decreases, and when it is less than 30 parts by mass, the afterglow brightness of the phosphorescence part 13 is influenced by the color of the base part 12. May be significantly lower. Moreover, when there are more compounding of a luminous pigment than 70 mass parts, although depending on the kind of high molecular compound and the particle size of a luminous pigment, fluidity | liquidity will fall and the tendency for cast molding to become difficult will be seen.

  Returning to FIG. 1, a method for manufacturing the phosphor 1 will be described. Before inserting the reinforcing member 7 into the inner cylinder 2 of the phosphorescent body 1, the phosphorescent body 11 is arranged from the back side (the lower side of FIG. 1B) of the inner cylinder 2 (arrangement step). In the arranged phosphorescent body 11, the phosphorescent portion 13 is located inside the inner wall portion 6, and the base portion 12 is located on the tip side of the inner wall portion 6. Next, the reinforcing member 7 is inserted into the inner cylinder 2 until the bottom surface of the reinforcing member 7 contacts the tip of the contact portion 5. Thereby, the luminous body 11 is held between the reinforcing member 7 and the inner wall portion 6.

  Since the area of the base 12 in the front view of the phosphorescent body 11 is set to be larger than the area of the phosphorescent section 13 in the front view, the tip of the inner wall 6 (see FIG. 1B) is placed on the top surface of the base 12. Can be located. As a result, since the phosphor 12 is prevented from being detached from the recess 3 a by the base portion 12, the phosphor 11 can be easily held between the support 3 and the reinforcing member 7. As a result, by attaching the phosphorescent body 1 to the tip of the pipe P or the reinforcing bar (not shown), the end of the pipe P or the reinforcing bar can be prevented from being exposed by the support body 3 and the outer cylinder 4, and the phosphorescent portion 13 phosphorescence can alert you at night.

  Moreover, since the phosphorescent part 13 is arrange | positioned in the recessed part 3a penetrated and formed in the support body 3, the phosphorescent part 13 according to the uses and purposes, such as guidance, a sign, alerting, etc., can be arrange | positioned in the support body 3. As a result, the versatility of the phosphor 11 can be improved and the application range can be expanded according to the shape of the support 3 and the like.

  Next, a second embodiment will be described with reference to FIG. In the first embodiment, the case where the base portion 12 and the phosphorescent portion 13 are in close contact with each other has been described. On the other hand, 2nd Embodiment demonstrates the case where the reflection layer 24 is interposed between the base part 22 and the luminous part 23. FIG. 3A is a perspective view of the phosphor 21 in the second embodiment, and FIG. 3B is a cross-sectional view of the mold 201, the base 22 and the phosphor 23 for explaining the manufacturing process of the phosphor 21. FIG. It is.

  As shown in FIG. 3A, the phosphorescent body 21 is stacked on the base portion 22 and on the front side with respect to the base portion 22 while being transparently formed in a substantially rectangular shape when viewed from the front. The phosphorescent part 23 which protruded and formed the geometric pattern is provided, and the reflection layer 24 interposed between the phosphorescent part 23 and the base | substrate part 22 is provided. In the present embodiment, the base portion 22 and the phosphorescent portion 23 are made of an epoxy resin, and a phosphorescent pigment and a colorant are mixed in the epoxy resin (polymer compound) constituting the phosphorescent portion 23. Since the phosphorescent pigment is the same as that described in the first embodiment, the description thereof is omitted.

  The base portion 22 includes a base portion 22a formed in a substantially flat plate shape, and a protruding portion 22b in which the center of the base portion 22a protrudes. Moreover, the light storage part 23 is provided with the 1st light storage part 23a and the 2nd light storage part 23b which are divided | segmented and arrange | positioned around the protruding part 22b. In the present embodiment, the protruding portion 22b is formed in a substantially circular shape when viewed from the front, and the first light storage portion 23a and the second light storage portion 23b are formed in a substantially C shape when viewed from the front. The first phosphorescent unit 23a and the second phosphorescent unit 23b are mixed with different types of phosphorescent pigments and configured to emit phosphorescent light of different colors. In addition, the height of the protruding portion 22b with respect to the base portion 22a is set to the same value as the height of the first light storage portion 23a and the second light storage portion 23b with respect to the base portion 22a.

  Next, with reference to FIG.3 (b), the manufacturing method of the luminous body 21 is demonstrated. The phosphorescent body 21 is manufactured by pouring a polymer compound into the second concave surface 203 and the two first concave surfaces 202 provided in the mold 201 and curing them. A cavity for molding the phosphorescent part 23 (first phosphorescent part 23a and second phosphorescent part 23b) and the reflective layer 24 is formed by the two first concave surfaces 202, and the base part 22 is molded by the second concave surface 203. A cavity is formed. In the present embodiment, the mold 201 is made of silicone, and the phosphor 21 is manufactured by casting.

  In order to manufacture the phosphor 21, first, a phosphorescent pigment and a colorant are mixed with an epoxy resin (polymer compound). Two types of polymer compounds in which different types of phosphorescent pigments are mixed are prepared. Next, the polymer compound in which one phosphorescent pigment and the colorant were mixed was poured into one first concave surface 202 (right side of FIG. 3B) of the mold 201, and the other phosphorescent pigment and the colorant were mixed. The polymer compound is poured into the other first concave surface 202 (left side of FIG. 3B) (phosphorescent part forming step). The polymer compound that forms the reflective layer 24 is applied to the place where the polymer compound poured into the first concave surface 202 has hardened and contracted (the place where the polymer compound is recessed and lowered with respect to the boundary with the second concave surface 203). (Reflective layer placement step). In the present embodiment, the reflective layer 24 (white reflective layer) is formed of a white paint in which a titanium resin powder is mixed with a polyester-based resin or the like.

  After the white paint is cured, a transparent epoxy resin (polymer compound) is poured into the second concave surface 203 of the mold 201 (base part molding step). The base portion 22 is bonded to the reflective layer 24 by the curing of the polymer compound poured into the second concave surface 203 (adhesion step). After the polymer compound is cured, the base portion 22, the phosphorescent portion 23 and the reflective layer 24 are removed from the mold 201 to obtain the phosphorescent body 21.

  According to the method for manufacturing the phosphorescent body 21 described above, the reflective layer 24 is disposed on the back surface of the phosphorescent portion 23, and the reflective layer 24 is sandwiched between the phosphorescent portion 23 and the base portion 22. As a result, phosphorescence due to the phosphorescent pigment is reflected to the front side (opposite side of the base portion 22), so that the afterglow luminance of the phosphorescent portion 23 can be improved in addition to the effects obtained in the first embodiment.

  In addition, since the polymer compound poured into the first concave surface 202 is cured and contracted (in the first concave surface 202), the polymer compound (white paint) that forms the reflective layer 24 is applied. It is possible to make it difficult for the white paint to protrude around 23. As a result, it is possible to prevent the appearance of the phosphor 21 from being deteriorated due to the white paint (reflective layer) that protrudes around the phosphorescent unit 23.

  In addition, since the base part 22 is formed by the epoxy resin having a weak water repellency compared with the silicone type, the phosphorescent body 21 can easily form an adhesive layer by applying an adhesive to the back surface of the base part 22. it can. Thereby, the application example of the attachment means of the luminous body 21 with respect to a target object (not shown) can be increased, and the application range of the luminous body 21 can be expanded.

  Moreover, since the phosphorescence part 23 (the 1st phosphorescence part 23a and the 2nd phosphorescence part 23b) is divided and formed in the several places (2 places in this Embodiment) of the front surface of the base | substrate part 22, the design property of the phosphorescence body 21 is formed. Can be improved. The phosphorescent portion 23 can be formed at an arbitrary position by appropriately designing the mold 201. Furthermore, since the 1st luminous part 23a and the 2nd luminous part 23b are set so that a mutually different color phosphorescence may be emitted, the design property of the luminous body 21 can further be improved.

  In the present embodiment, the case where the reflective layer 24 is formed by applying a white paint has been described. However, the present invention is not necessarily limited to this, and as in the case where the base portion 22 and the phosphorescent portion 23 are formed, a high It is naturally possible to form the reflective layer 24 by pouring molecular compounds. In addition, it is naturally possible to form the reflective layer 24 by arranging and sandwiching a white sheet (white formed material) prepared in advance between the first phosphorescent portion 23a and the second phosphorescent portion 23b and the base portion 22. is there.

  Next, a third embodiment will be described with reference to FIG. In 1st Embodiment and 2nd Embodiment, the case where the base parts 12 and 22 made from a high molecular compound were formed by mold shaping was demonstrated. On the other hand, in 3rd Embodiment, the case where the separately prepared base part 32 is adhere | attached on the luminous part 33 and the luminous body 31 is manufactured is demonstrated. FIG. 4A is a perspective view of the phosphorescent body 31 according to the third embodiment, and FIG. 4B is a cross-sectional view of the mold 301 and the phosphorescent portion 33 for explaining the manufacturing process of the phosphorescent body 31.

  As shown in FIG. 4A, the phosphorescent body 31 has a base portion 32 formed in a substantially rectangular shape when viewed from the front, and is stacked on the base portion 32 and protrudes to the front side with respect to the base portion 32. And a phosphorescent unit 33 in which a graphic symbol (arrow) is formed. In the present embodiment, the base portion 32 is made of a flexible cloth, and a phosphorescent pigment and a colorant are mixed with the silicone rubber (polymer compound) constituting the phosphorescent portion 33. Since the phosphorescent pigment is the same as that described in the first embodiment, the description thereof is omitted.

  Next, with reference to FIG.4 (b), the manufacturing method of the phosphor 31 is demonstrated. The phosphorescent body 31 is manufactured by pouring a polymer compound into a concave surface 302 provided in the mold 301 and curing it to form the phosphorescent portion 33 and bonding the base portion 32 to the phosphorescent portion 33. A cavity for molding the phosphorescent portion 33 is formed by the concave surface 302. In the present embodiment, the forming die 301 is made of an aluminum alloy (made of metal), and the phosphor 31 is manufactured by casting.

  In order to manufacture the phosphorescent body 31, first, a phosphorescent pigment and a colorant are mixed with silicone (polymer compound). Next, a liquid polymer compound in which the phosphorescent pigment and the colorant are mixed is poured into the concave surface 302 of the mold 301 (phosphorescent part molding step). When the polymer compound poured into the concave surface 302 is cured and shrunk (where it is dented and becomes lower than the height of the upper surface of the mold 301), a transparent polymer compound (in this embodiment, phosphorescent light is stored). (Silicone without pigments and colorants).

  Before the transparent polymer compound poured into the concave surface 302 is cured, the base portion 32 (made of cloth) is placed on the upper surface of the mold 301 to bring the polymer compound in the concave surface 302 into contact with the base portion 32. Silicone (liquid polymer compound) penetrates between the fibers of the base portion 32. By the curing of the polymer compound, the phosphorescent portion 33 and the base portion 32 are bonded mainly by the anchor effect (bonding step). After the phosphorescent part 33 and the base part 32 are bonded, the phosphorescent part 33 is removed from the mold 301 to obtain the phosphor 31.

  According to the method for manufacturing the phosphorescent body 31 described above, the phosphorescent part 33 is bonded to the base part 32 by curing of the polymer compound poured into the mold 301 (concave surface 302). By curing the polymer compound constituting the phosphorescent part 33 and bonding the base part 32 simultaneously, the polymer compound constituting the phosphorescent part 33 is cured, and then the phosphorescent part 33 is adhered to the base part 32. Compared with the case, the manufacturing process of the phosphor 31 can be shortened.

  In addition, after the shrinkage of the polymer compound mixed with the phosphorescent pigment, a transparent polymer compound is poured into the concave surface 302 and the polymer compound in the concave surface 302 is brought into contact with the base portion 32. The inner polymer compound can be reliably brought into contact. In addition, since the shrinkage (so-called sink) of the polymer compound in the concave surface 302 can be compensated, it is possible to prevent the bonding strength between the phosphorescent portion 33 and the base portion 32 from being reduced due to the shrinkage of the polymer compound in the concave surface 302. . Further, even when the polymer compound protrudes around the phosphorescent portion 33 and hardens, the appearance of the phosphor 31 can be prevented from deteriorating because the polymer compound is transparent.

  In addition, since the cloth base part 32 is fixed to the back surface of the base part 33 and the size of the base part 32 in the front view is set larger than that of the phosphorescent part 33 in the front view, the cloth base part 32 is made of cloth on the surface of clothes or the like (target object). The base portion 32 can be sewn. In addition, it is also possible to affix the base | substrate part 32 to the surface of clothes etc. (target object) by providing the back surface of the base | substrate part 32 with the heat bonding layer fuse | melted with heat, such as an iron.

  The base portion 32 is formed of a flexible member (made of cloth), and the phosphorescent portion 33 is formed of a silicone polymer compound. The phosphorescent portion 33 is bonded to the base portion 32 by the curing of the silicone polymer compound. Since the silicone polymer compound penetrates between the fibers of the base portion 32 (cloth) and is cured, the phosphorescent portion 33 is firmly bonded to the base portion 32 by the anchor effect. Further, since the silicone polymer compound becomes rubber after curing, the flexibility of the base portion 32 is also maintained. As a result, the flexibility of the base part 32 to which the phosphorescent part 33 is bonded can be maintained.

  Note that the adhesion mechanism between the silicone polymer compound and the base portion 32 is not limited to the anchor effect. Depending on the type of the base portion 32, it is naturally possible to bond the surface of the base portion 32 and the phosphorescent portion 33 by a chemical reaction.

  The present invention has been described above based on the embodiments. However, the present invention is not limited to the above embodiments, and various improvements and modifications can be made without departing from the spirit of the present invention. It can be easily guessed. For example, the shapes and sizes of the base parts 12, 22, 32 and the phosphorescent parts 13, 23, 33 are appropriately designed according to the purpose of the phosphorescent bodies 11, 21, 31.

  In the first embodiment, the case where the phosphorescent body 11 is molded using a polymer compound made of condensation type one-component silicone (modified silicone) is described. However, other polymer compounds may be used. Of course it is possible. Examples of other polymer compounds include addition type silicones, polyurethane resins, epoxy resins, polyester resins, acrylic resins, and ultraviolet curable resins. In addition, the polymer compound is not limited to a one-component (one-component) resin, and it is naturally possible to use a multi-component resin such as a two-component resin.

  In consideration of the material and shape of the phosphor 11 and the durability of the mold 101, the material of the mold 101 can be set as appropriate. In addition, as in the first embodiment, other polymer compounds can naturally be employed for the polymer compounds in the second embodiment and the third embodiment. Note that the first embodiment and the second embodiment may be vacuum casting in which casting is performed under reduced pressure.

  In the said 1st Embodiment and 2nd Embodiment, although the case where the phosphorescent bodies 11 and 21 were manufactured by cast molding was demonstrated, it is not necessarily restricted to this and employ | adopting another shaping | molding means. Of course it is possible. Examples of other molding means include injection molding, hollow molding, and compression molding. When the phosphors 11 and 21 are manufactured by injection molding, hollow molding, or compression molding, metal molds 101 and 201 are used and combined with another mold to form a cavity.

  When manufacturing phosphorescent bodies 11 and 21 by injection molding or hollow molding, a master batch of polymer compound (synthetic resin, synthetic rubber, etc.) and phosphorescent pigment (about half the target value to be finally kneaded) are mixed Etc., and knead using an extruder or the like while heating to a predetermined temperature. Next, the obtained kneaded product and the phosphorescent pigment (remaining amount to be finally kneaded) are mixed using a mixer or the like, and kneaded using an extruder or the like while being heated to a predetermined temperature.

  If the phosphorescent pigment is kneaded at once without dividing into multiple times, the fluidity when kneading the master batch of the polymer compound and the phosphorescent pigment is lowered, and the dispersibility of the phosphorescent pigment is lowered. There is a tendency to In contrast, the fluidity can be improved by kneading the phosphorescent pigment in a plurality of times, and the dispersibility of the phosphorescent pigment can be improved. As a result, it is possible to prevent the phosphorescent pigment from being unevenly distributed in a part of the phosphorescent portions 13 and 23. Then, the polymer compound heated to the softening temperature is poured into a mold by applying an injection pressure, filled into a cavity, and molded.

  When manufacturing phosphorescent body by compression molding, mix powdery (granular) polymer compound (mainly thermosetting resin) and phosphorescent pigment, pour them into the mold cavity, then heat Then, it is cured and molded by applying pressure.

  In the said 1st Embodiment, although the phosphor 1 as a protective device (safety goods) which prevents that the end part of the pipe P or a reinforcing bar becomes exposed was demonstrated, it is not necessarily restricted to this, The support body 3 Of course, it is possible to use the phosphorescent body as a guide plate, a sign, or the like by appropriately designing the shape and size of the lamp.

  Further, since the phosphors 11, 21, 31 described in the above embodiment can be formed into arbitrary shapes, the phosphors 11, 21, 31 are made of toys such as mascots, pendants, key holders, accessories such as daily goods, name tags, etc. Of course, building members such as flooring and curbs, and civil engineering members are possible.

  In the said embodiment, although the case where the one phosphorescence part 13,23,33 was arrange | positioned on the surface of the base | substrate parts 12,22,32 was demonstrated, it is not necessarily restricted to this, and physically separated 2 It is naturally possible to provide the above phosphorescent part on the surface of the base part.

  In the said 1st Embodiment, although the case where the support body 3 was formed in plate shape (planar shape) was demonstrated, it is not necessarily restricted to this, A lump shape (three-dimensional shape) according to the form of a luminous body It is naturally possible to form.

  Moreover, although the case where the concave portion 3a is formed through the support body 3 has been described, the present invention is not necessarily limited to this. When the support body is formed in a lump shape, the concave portion is formed in a depression shape on the surface of the support body. Of course, it is possible to make it possible to attach a phosphorescent body to the recess.

  In the said 1st Embodiment and 2nd Embodiment, about the case where the phosphorescence body 11 and 21 is manufactured by joining (adhering) the phosphorescence part 13 and 23 and the base | substrate parts 12 and 22 with one shaping | molding die 101,201. explained. However, the present invention is not necessarily limited to this, and it is possible to make the mold for molding the phosphorescent parts 13 and 23 different from the mold for joining (adhering) the phosphorescent parts 13 and 23 to the base parts 12 and 22. It is.

  In this case, first, the phosphorescent portions 13 and 23 are molded by one molding die (not shown). In this case, various molding methods such as cast molding, injection molding, and compression molding can be employed. Thereafter, the molded phosphorescent portions 13 and 23 are arranged (temporarily fixed) on the cavity inner surface of another mold (not shown) (phosphorescent portion arranging step). Next, a polymer compound is poured into another mold (cavity) in which the phosphorescent portions 13 and 23 are arranged, and the phosphorescent portions 13 and 23 are bonded to the base portions 12 and 22 while the base portions 12 and 22 are molded. (Phosphorescent part adhesion process). In this case, various molding methods such as cast molding, injection molding, compression molding, and the like can be employed for molding the base portions 12 and 22. As described above, the first embodiment also applies when the mold for molding the phosphorescent parts 13 and 23 is different from the mold for joining (adhering) the phosphorescent parts 13 and 23 and the base parts 12 and 22. Or the effect acquired by 2nd Embodiment is realizable.

  In addition, the phosphorescent portions 13 and 23 are not molded by cast molding, injection molding, compression molding, or the like, but a phosphorescent material such as a phosphorescent sheet containing a phosphorescent pigment or a ceramic plate (a substrate made of an inorganic material) having a property of emitting phosphorescence ( Naturally, it is possible to prepare and use a “light-storing member” hereinafter in a predetermined outer shape. In that case, first, a phosphorescent member (phosphorescent portion) prepared in a predetermined shape is arranged on the inner surface of the cavity of the mold (phosphorescent portion arranging step). Next, the polymer compound is poured into a mold (in the cavity) in which the phosphorescent member (phosphorescent part) is arranged, and the phosphorescent part is bonded to the base part while the base part is molded (phosphorescent part bonding step). In this case as well, various molding methods such as cast molding, injection molding, compression molding, and the like can be adopted for molding the base portion, and the effects obtained in the first embodiment or the second embodiment can be realized.

  It is naturally possible to provide an adhesive layer on the back surface of the phosphorescent member (phosphorescent portion). As the adhesive layer, a heat-sensitive or pressure-sensitive polymer compound suitable for the polymer compound material is appropriately selected. It is naturally possible to provide a reflective layer (white reflective layer) on the back surface of the phosphorescent member (phosphorescent portion). As the reflection layer, a coating layer formed on the back surface of the phosphorescent member (phosphorescent portion) by applying a white paint, or a white sheet disposed on the back surface of the phosphorescent member (phosphorescent portion) can be used. It is naturally possible to provide an adhesive layer on the white sheet (reflective layer).

  In the third embodiment, the case where the base portion 32 is made of cloth has been described. However, the present invention is not necessarily limited to this, and other materials and members can naturally be used. Other materials and components include, for example, sheets and wallpaper made of paper or synthetic resin; leather (natural leather, artificial leather); synthetic resin, glass, metal plate; metal or synthetic resin mesh Tile (made of inorganic material) and the like. Of course, a retroreflective plate made of synthetic resin or the like can be used as the base portion 32. Since various materials and members can be employed as the base portion 32, the usage of the phosphorescent body 31 can be expanded.

  In addition, when a thing having meshes (gap between fibers or wires) such as paper, leather, etc. (fiber aggregate) or nets is adopted as the base portion 32, the polymer compound is filled in the mesh. The anchor effect is obtained by curing. Silicone (silicone rubber) is a difficult-to-adhere material, but the adhesive strength between the base portion 32 and the phosphorescent portion 33 can be improved by utilizing the anchor effect.

  In the third embodiment, the case where the base portion 32 is bonded simultaneously with the curing of the phosphorescent portion 33 has been described. However, the present invention is not necessarily limited thereto, and the phosphorescent portion 33 is molded (cured) and then bonded. It is naturally possible to bond the phosphorescent part 33 to the base part 32 using an agent or the like. In that case, in order to improve the adhesive strength between the base part 32 and the phosphorescent part 33, the base part 32 and the phosphorescent part 33 can be subjected to a primer treatment.

  Moreover, it is naturally possible to provide the reflection layer 24 described in the second embodiment on the phosphors 11 and 31 described in the first and third embodiments. By providing the reflective layer 24 on the back surfaces of the light storage units 13 and 33, the afterglow luminance of the light storage units 13 and 33 can be improved. Instead of providing the reflection layer 24, it is naturally possible to make the base portions 12 and 32 white and reflect the phosphorescence of the phosphorescent portions 13 and 33 by the base portions 12 and 32.

  The thickness of the phosphorescent portions 13, 23 and 33 (including the phosphorescent member) is 0.5 mm to 10 cm, depending on the particle size of the phosphorescent pigment and the color (background color) and size of the base portions 12, 22, and 32. Are preferably used. This is to make the afterglow luminance of the phosphorescent units 13, 23, and 33 (including the phosphorescent member) less susceptible to the colors of the base units 12, 22, and 32.

  In the present embodiment, the case where the phosphorescent units 13, 23, and 33 contain sulfur-based or oxide-based phosphorescent pigments has been described. However, the present invention is not necessarily limited to this, and absorbs energy of excitation light from the outside. Thus, it is naturally possible to employ other phosphorescent pigments that emit phosphorescence. Moreover, although the case where the luminous parts 13, 23, and 33 contain a colorant has been described, the colorant is not necessarily required.

  The present invention relates to a method for producing a phosphor, and in particular, to produce a phosphor capable of suppressing phosphorescent pigments that do not contribute to emitting phosphorescence, and easily increasing the afterglow luminance, and making it difficult to cause variations in position of phosphorescent sites. It is about the method.

  Conventionally, as a means for causing a part of the surface of a member to emit light by phosphorescence, a phosphorescent layer containing a phosphorescent pigment is formed on the entire surface of the base sheet, and the phosphorescent layer is partially hidden by masking. Yes. Masking is performed by sticking an adhesive sheet on the surface of the base sheet or printing a paste for printing on the surface of the base sheet. In this case, since the phosphorescent layer concealed by masking is not used for emitting phosphorescence, there is a problem that the phosphorescent pigment contained in the concealed phosphorescent layer is wasted.

  Therefore, as a technique for partially forming a phosphorescent layer on the surface of a member, for example, a base sheet on which a phosphorescent pattern layer (phosphorescent layer) containing a phosphorescent pigment is formed is fed into a molding die and the molding die is closed. After that, a technique is known in which a molten resin is injected and filled into a cavity, and a phosphorescent pattern layer is adhered to the surface of the molded body simultaneously with molding (Patent Document 1). With the technique disclosed in Patent Document 1, since the phosphorescent layer can be partially formed without masking, it is possible to prevent the occurrence of phosphorescent pigments that do not contribute to emitting phosphorescence.

Japanese Patent No. 3527344

  However, in the technology disclosed in Patent Document 1, the phosphorescent pattern layer (phosphorescent layer) is made by a normal printing method such as an offset printing method, a gravure printing method, a screen printing method, etc. The thickness (dry thickness) was about 60 to 150 μm. Since the phosphorescent layer is formed on the surface of the molded body by adhering it in the molding die, the thickness of the phosphorescent layer on the surface of the molded body was also about 60 to 150 μm. The afterglow brightness of the phosphorescent layer tends to increase in proportion to the thickness of the phosphorescent layer, but it is difficult to increase the thickness of the phosphorescent layer by the printing method. For this reason, there is a problem that it is difficult to increase the afterglow luminance unless the type or blending amount of the phosphorescent pigment contained in the phosphorescent layer is changed.

  In the technique disclosed in Patent Document 1, the base sheet fed into the cavity moves in the cavity by the molten resin filled in the cavity, and is finally pressed against the inner surface of the cavity. The phosphorescent layer formed on the base sheet is adhered to the surface of the molten resin (molded body) at a position sandwiched between the molten resin and the inner surface of the cavity. Since the base sheet moves in the cavity during molding and bonding, there is a problem that the position of the phosphorescent layer with respect to the surface of the molded body tends to vary.

  The present invention has been made to solve the above-described problems, and can suppress phosphorescent pigments that do not contribute to emitting phosphorescence, and can easily increase the afterglow luminance and hardly cause variation in position of phosphorescent emitting portions. It aims at providing the manufacturing method of the phosphorescent material which can be performed.

Means for Solving the Problems and Effects of the Invention

  In order to achieve this object, according to the method for producing a phosphorescent body according to claim 1, the polymer compound mixed with the phosphorescent pigment has a surface or a base portion to be contacted with the base portion attached to the object.

The base part is bonded to the back surface of the phosphorescent part molded by the phosphorescent part molding process by the bonding process, and the phosphorescent part protrudes partially on the front side with respect to the base part. Since the phosphorescent pigment is mixed in the phosphorescent portion, the phosphorescent pigment that emits phosphorescence can be disposed at a specific location on the front side of the base portion. As a result, there is an effect of suppressing phosphorescent pigments that do not contribute to emitting phosphorescence.

  Moreover, since the phosphorescent part is poured into a mold and molded, the shape of the phosphorescent part can be set as appropriate by designing the mold appropriately, and the thickness of the phosphorescent part can be easily increased. The afterglow brightness of the phosphorescent part mixed with the phosphorescent pigment increases in proportion to the thickness of the phosphorescent part at a predetermined thickness where the excitation light cannot be transmitted. There is.

  Further, the position of the phosphorescent portion is determined by the first concave surface provided in the mold, and does not move even when bonded to the base portion. Therefore, there is an effect that it is difficult to cause variation in the position of the phosphorescent portion with respect to the base portion. Moreover, since the phosphorescent part is formed so as to protrude to the front side with respect to the base part, there is an effect that the phosphorescent body can be made three-dimensional and the visual interest can be improved.

  Furthermore, since the predetermined | prescribed design visually recognized under visible light is formed in the front of a base | substrate part by the phosphorescence part, there exists an effect which can improve the visual interest under visible light.

Moreover, the base part is set so that the area in front view is larger than the area in front view of the phosphorescent part. Since the base part is a part to be attached to the object, the base part can be easily attached to the object by setting the area of the base part in the front view larger than the area in the front view of the phosphorescent part. . As a result, there is an effect that the flexibility in attaching the phosphorescent body to the object can be improved.
Furthermore, a reflective layer that reflects phosphorescence of the phosphorescent pigment is disposed in the first concave surface on the back surface of the phosphorescent portion molded into the first concave surface by the phosphorescent portion molding step. Since the reflective layer arranged by the reflective layer arranging step is sandwiched between the phosphorescent part and the base part, there is an effect that the afterglow luminance of the phosphorescent part can be improved.

  According to the method for manufacturing a phosphorescent body according to claim 2, the adhering step adheres the phosphorescent portion to the base portion by curing the polymer compound poured into the mold by the phosphorescent portion molding step. Compared to the case where the polymer compound constituting the phosphorescent part is cured and then the phosphorescent part is adhered to the base part by simultaneously curing the polymer compound constituting the phosphorescent part and bonding the base part. The manufacturing process of the phosphor can be shortened. Therefore, in addition to the effect of Claim 1, there exists an effect which can shorten the manufacturing process of a luminous body.

  According to the method for manufacturing a phosphorescent body according to claim 3, after the phosphorescent part molding step, the polymer compound is recessed in the molding die by the base part molding step, and the back surface from the area of the first concave surface in the rear view. The base portion is molded by pouring into the second concave surface having a large area in view. In the bonding step, the phosphorescent portion is bonded to the base portion by curing of the polymer compound poured into the mold in the base portion forming step. Compared with the case where the base part is bonded to the phosphorescent part after curing the polymer compound constituting the base part by simultaneously curing the polymer compound constituting the base part and bonding the phosphorescent part. The manufacturing process of the phosphor can be shortened. Therefore, in addition to the effect of Claim 1 or 2, there exists an effect which can shorten the manufacturing process of a phosphorescent body.

  According to the method for manufacturing the phosphor of claim 4, the base portion is formed of a flexible member. The phosphorescent portion is formed of a silicone polymer compound and is bonded to the base portion by curing. Since the silicone polymer compound is cured to be rubbery, it is bonded while maintaining the flexibility of the base portion. As a result, in addition to the effect of claim 2, there is an effect that the flexibility of the base part to which the phosphorescent part is bonded can be maintained.

According to the method for manufacturing a phosphorescent body according to claim 5, the phosphorescent part containing the phosphorescent pigment is recessed in the cavity inner surface of the molding die in which the base part attached to the object is molded by the phosphorescent part arranging step. The first concave surface is disposed. The polymer compound is poured into the cavity where the phosphorescent part is arranged by the phosphorescent part arranging step, the phosphorescent part is bonded to the base part while the base part is molded by the phosphorescent part adhering process, and the phosphorescent part is bonded to the base part. Is provided in a partially protruding manner on the front side. The area of the base portion is set larger than the area of the phosphorescent portion in the front view.

Moreover, the reflective layer which reflects the phosphorescence of a phosphorescent pigment is arrange | positioned by the reflective layer arrangement | positioning process in the back surface of the phosphorescent part arrange | positioned by the phosphorescent part arrangement | positioning process at the 1st concave surface. Since the reflective layer arranged by the reflective layer arranging step is sandwiched between the phosphorescent part and the base part, there is an effect that the afterglow luminance of the phosphorescent part can be improved.

According to the method for producing a phosphorescent body according to claim 6 , since the phosphorescent parts are separately formed or arranged at two or more locations in front of the base part, in addition to the effect of any one of claims 1 to 5 , the phosphorescent body There is an effect that can improve the design.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the accompanying drawings. First, the phosphor 1 will be described with reference to FIG. FIG. 1 is a perspective view of the phosphor 1 in the first embodiment of the present invention, and FIG. 1B is an axial sectional view of the phosphor 1. As shown to Fig.1 (a) and FIG.1 (b), the luminous body 1 is a cap attached to the edge part of a steel pipe (pipe P) or a reinforcing bar (not shown), It is a protective device (safety article) that prevents the end from being exposed.

  As shown in FIG. 1A, the phosphorescent body 1 is positioned outside the inner cylinder 2, the inner cylinder 2 formed in a cylindrical shape, the substantially disk-shaped support body 3 provided at one end of the inner cylinder 2, and the inner cylinder 2. It mainly includes an outer cylinder 4 extending in the axial direction from the outer periphery of the support 3, a recess 3 a formed through substantially the center of the support 3, and a phosphorescent body 11 attached to the recess 3 a. The inner cylinder 2, the support body 3, the outer cylinder 4, and the like constituting the phosphorescent body 1 are integrally formed of a synthetic resin such as polyethylene.

  As shown in FIG.1 (b), the inner cylinder 2 is a site | part inserted by the pipe P, and the support body 3 is provided in the end. The support 3 is a part that is hit by a hammer or the like when the inner cylinder 2 is fitted into the pipe P, and an outer cylinder 4 whose tip abuts against the end of the pipe P is provided on the outer periphery. The contact portion 5 is a pin-shaped or annular portion located outside the inner wall portion 6 forming the recess 3 a and inside the inner cylinder 2, and has a bottomed cylindrical shape fitted into the inner cylinder 2. The bottom part of the reinforcing member 7 contacts.

  The reinforcing member 7 is a member made of synthetic resin such as nylon for reinforcing the inner cylinder 2, and a cylindrical hole 7a is formed at the center of the shaft. The hole 7a is a part into which a reinforcing bar (not shown) whose outer diameter is smaller than the outer diameter of the pipe P is inserted. Since the hole 7a is formed in the reinforcing member 7, the phosphor 1 can be attached to the end of the reinforcing bar by inserting a reinforcing bar (not shown) in the hole 7a instead of the pipe P. The inner wall portion 6 is a portion for holding the phosphor 11 in a space surrounded by the bottom surface of the reinforcing member 7 and the contact portion 5, and has an axial length (vertical length in FIG. 1 (b)). It is set smaller than the axial length of the contact portion 5.

  The phosphorescent body 11 includes a base portion 12 formed in a flat plate shape, and a phosphorescent portion 13 that is integrally formed so as to protrude from the front side of the base portion 12 (upper surface side, upper side in FIG. 1B). Yes. The area of the base part 12 is set to be larger than the area of the phosphorescent part 13 in the front view, and the base part 12 is located between the reinforcing member 7 and the inner wall part 6, and is located inside the inner wall part 6. The phosphorescent part 13 is located. Further, since the thickness of the base portion 12 (the vertical dimension in FIG. 1 (b)) is set to a value substantially equal to the difference between the axial lengths of the abutment portion 5 and the inner wall portion 6, it is located inside the recess 3a. The phosphorescent part 13 can be arrange | positioned. Furthermore, since the thickness of the phosphorescent portion 13 is set to be the same as or slightly smaller than the axial length of the inner wall portion 6, the phosphorescent portion 13 is arranged flush with the support 3 or slightly recessed. As a result, it is possible to prevent the phosphorescent portion 13 from being hit when the support 3 is hit with a hammer or the like while ensuring the visibility of the phosphorescent portion 13.

  Next, the phosphor 11 will be described with reference to FIG. FIG. 2A is a perspective view of the phosphorescent body 11, and FIG. 2B is a cross-sectional view of the mold 101, the base part 12, and the phosphorescent part 13 for explaining the manufacturing process of the phosphorescent body 11. As shown in FIG. 2A, the phosphorescent body 11 has a base portion 12 formed in a substantially circular shape when viewed from the front, and is stacked on the base portion 12 and protrudes toward the front side with respect to the base portion 12. And a substantially circular light storage portion 13 when viewed from the front. In the present embodiment, the base portion 12 and the phosphorescent portion 13 are made of silicone (made of silicone rubber), and a phosphorescent pigment is mixed with the silicone (polymer compound) constituting the phosphorescent portion 13.

As the phosphorescent pigment, one or a plurality of pigments having a function of sustaining light emission for a relatively long time in a dark place when irradiated with sunlight or artificial illumination light is used. For example, sulfur-based or oxide-based phosphorescent pigments can be used. Examples of sulfur-based phosphorescent pigments include calcium sulfide / bismuth and zinc sulfide / copper. Examples of the oxide-based phosphorescent pigment include compounds represented by M ¹ Al ₂ O ₄ , M ² Al ₁₄ O ₂₅ (where M ¹ and M ² are at least one of calcium, strontium, and barium). The thing which uses one or both as a mother crystal can be mentioned.

  The phosphorescent portion 13 is mixed with a colorant in addition to the phosphorescent pigment, and is prepared to have a color different from that of the base portion 12, thereby forming a predetermined pattern (circle in the present embodiment) that is visible under visible light. ing. Thereby, the visual interest under visible light can be improved also in the bright time (under irradiation of light of sunlight or artificial lighting) in which the phosphorescent unit 13 does not emit phosphorescence. Note that the pattern by the phosphorescent unit 13 is not limited to a geometric pattern such as a circle, and other graphic symbols, characters, patterns, and the like can be employed.

  Next, with reference to FIG.2 (b), the manufacturing method of the luminous body 11 is demonstrated. The phosphorescent body 11 is manufactured by pouring a polymer compound into the first concave surface 102 and the second concave surface 103 that are recessed in the molding die 101 and curing them. A cavity for molding the phosphorescent portion 13 is formed by the first concave surface 102, and a cavity for molding the base portion 12 is formed by the second concave surface 103. In the present embodiment, the mold 101 is made of FRP, and the phosphor 11 is manufactured by casting.

  In order to manufacture the phosphor 11, first, a phosphorescent pigment and a colorant are mixed with a polymer compound made of a condensation type one-component silicone (modified silicone) containing a modified silicone as a main component. Next, a liquid polymer compound in which the phosphorescent pigment and the colorant are mixed is poured into the first concave surface 102 of the mold 101 (phosphorescent part molding step). Before the polymer compound poured into the first concave surface 102 is completely cured, the modified silicone-based (condensation type one-component system) polymer compound not mixed with the phosphorescent pigment is used as the second concave surface of the mold 101. Pour into 103 (base part forming step). The polymer compound (phosphorescent part 13) poured into the second concave surface 103 is bonded to the base part 12 by the curing of the polymer compound (base part 12 and phosphorescent part 13) poured into the first concave surface 102 (adhesion). Process). After the polymer compound is cured, the base portion 12 and the phosphorescent portion 13 are removed from the mold 101 to obtain the phosphorescent body 11.

  According to the method for manufacturing the phosphorescent body 11 described above, the phosphorescent part 13 is mixed with the phosphorescent pigment, so that the phosphorescent pigment that emits phosphorescence can be arranged at a specific location on the front side of the base part 12. When the phosphorescent layer containing the phosphorescent pigment is partially concealed by masking, the phosphorescent pigment contained in the concealed phosphorescent layer is wasted, but according to this production method, the phosphorescent pigment that does not contribute to emitting phosphorescence is used. Can be suppressed. As a result, the amount of phosphorescent pigment required by the phosphorescent body 11 (the cost of the phosphorescent pigment) can be reduced.

  Moreover, since the phosphorescent part 13 is poured and shape | molded in the shaping | molding die 101, the shape of the luminous part 13 can be set suitably by designing the shaping | molding die 101 (1st concave surface 102) suitably. Further, the thickness of the phosphorescent portion 13 can be easily increased. The afterglow luminance of the phosphorescent unit 13 mixed with the phosphorescent pigment increases in proportion to the thickness of the phosphorescent unit 13 at a predetermined thickness where the excitation light does not pass through. Therefore, the afterglow luminance can be easily increased. it can.

  Further, the position of the phosphorescent portion 13 relative to the base portion 12 is determined by the positional relationship of the first concave surface 102 (cavity inner surface) and the second concave surface 103 of the mold 101, and the base portion 12 and the phosphorescent portion 13 are bonded to each other. Since it does not change when it is done, it is possible to make it difficult for the phosphor portion 13 to have a positional variation with respect to the base portion 12.

  Further, since the polymer compound constituting the base portion 12 is cured and the phosphorescent portion 13 is bonded at the same time, after the polymer compound constituting the base portion 12 is cured, the base portion 12 is bonded to the phosphorescent portion 13. Compared with the case where it does, the manufacturing process of the luminous body 11 can be shortened. In particular, since the curing of the base portion 12 and the phosphorescent portion 13 and the adhesion between the phosphorescent portion 13 and the base portion 12 are performed at the same time, it is affected by the wettability of the polymer compound (the phosphorescent portion 13) after curing. In addition, the bonding strength between the base portion 12 and the phosphorescent portion 13 can be ensured.

  Further, since the phosphor 11 is manufactured by cast molding, the manufacturing cost of the molding die 101 can be suppressed, and small lot production can be realized. Furthermore, since the phosphorescent pigment is mixed with the liquid polymer compound poured into the mold 101, the blending ratio of the phosphorescent pigment with respect to the phosphorescent portion 13 can be increased. As a result, the afterglow brightness of the light storage unit 13 can be improved.

  Here, the phosphorescent pigment is mixed at a ratio of 3 to 70 parts by mass, preferably 30 to 70 parts by mass with respect to 100 parts by mass of the total mass of the polymer compound and the phosphorescent pigment poured into the first concave surface 102. Thereby, the afterglow brightness | luminance of the phosphorescence part 13 is securable, ensuring the fluidity | liquidity of a liquid polymer compound. In addition, the afterglow brightness | luminance of the phosphorescence part 13 tends to fall as the mixture of the phosphorescent pigment decreases, and when it is less than 30 parts by mass, the afterglow brightness of the phosphorescence part 13 is influenced by the color of the base part 12. May be significantly lower. Moreover, when there are more compounding of a luminous pigment than 70 mass parts, although depending on the kind of high molecular compound and the particle size of a luminous pigment, fluidity | liquidity will fall and the tendency for cast molding to become difficult will be seen.

  Returning to FIG. 1, a method for manufacturing the phosphor 1 will be described. Before inserting the reinforcing member 7 into the inner cylinder 2 of the phosphorescent body 1, the phosphorescent body 11 is arranged from the back side (the lower side of FIG. 1B) of the inner cylinder 2 (arrangement step). In the arranged phosphorescent body 11, the phosphorescent portion 13 is located inside the inner wall portion 6, and the base portion 12 is located on the tip side of the inner wall portion 6. Next, the reinforcing member 7 is inserted into the inner cylinder 2 until the bottom surface of the reinforcing member 7 contacts the tip of the contact portion 5. Thereby, the luminous body 11 is held between the reinforcing member 7 and the inner wall portion 6.

  Since the area of the base 12 in the front view of the phosphorescent body 11 is set to be larger than the area of the phosphorescent section 13 in the front view, the tip of the inner wall 6 (see FIG. 1B) is placed on the top surface of the base 12. Can be located. As a result, since the phosphor 12 is prevented from being detached from the recess 3 a by the base portion 12, the phosphor 11 can be easily held between the support 3 and the reinforcing member 7. As a result, by attaching the phosphorescent body 1 to the tip of the pipe P or the reinforcing bar (not shown), the end of the pipe P or the reinforcing bar can be prevented from being exposed by the support body 3 and the outer cylinder 4, and the phosphorescent portion 13 phosphorescence can alert you at night.

  Moreover, since the phosphorescent part 13 is arrange | positioned in the recessed part 3a penetrated and formed in the support body 3, the phosphorescent part 13 according to the uses and purposes, such as guidance, a sign, alerting, etc., can be arrange | positioned in the support body 3. As a result, the versatility of the phosphor 11 can be improved and the application range can be expanded according to the shape of the support 3 and the like.

  Next, a second embodiment will be described with reference to FIG. In the first embodiment, the case where the base portion 12 and the phosphorescent portion 13 are in close contact with each other has been described. On the other hand, 2nd Embodiment demonstrates the case where the reflection layer 24 is interposed between the base part 22 and the luminous part 23. FIG. 3A is a perspective view of the phosphor 21 in the second embodiment, and FIG. 3B is a cross-sectional view of the mold 201, the base 22 and the phosphor 23 for explaining the manufacturing process of the phosphor 21. FIG. It is.

  As shown in FIG. 3A, the phosphorescent body 21 is stacked on the base portion 22 and on the front side with respect to the base portion 22 while being transparently formed in a substantially rectangular shape when viewed from the front. The phosphorescent part 23 which protruded and formed the geometric pattern is provided, and the reflection layer 24 interposed between the phosphorescent part 23 and the base | substrate part 22 is provided. In the present embodiment, the base portion 22 and the phosphorescent portion 23 are made of an epoxy resin, and a phosphorescent pigment and a colorant are mixed in the epoxy resin (polymer compound) constituting the phosphorescent portion 23. Since the phosphorescent pigment is the same as that described in the first embodiment, the description thereof is omitted.

  The base portion 22 includes a base portion 22a formed in a substantially flat plate shape, and a protruding portion 22b in which the center of the base portion 22a protrudes. Moreover, the light storage part 23 is provided with the 1st light storage part 23a and the 2nd light storage part 23b which are divided | segmented and arrange | positioned around the protruding part 22b. In the present embodiment, the protruding portion 22b is formed in a substantially circular shape when viewed from the front, and the first light storage portion 23a and the second light storage portion 23b are formed in a substantially C shape when viewed from the front. The first phosphorescent unit 23a and the second phosphorescent unit 23b are mixed with different types of phosphorescent pigments and configured to emit phosphorescent light of different colors. In addition, the height of the protruding portion 22b with respect to the base portion 22a is set to the same value as the height of the first light storage portion 23a and the second light storage portion 23b with respect to the base portion 22a.

  Next, with reference to FIG.3 (b), the manufacturing method of the luminous body 21 is demonstrated. The phosphorescent body 21 is manufactured by pouring a polymer compound into the second concave surface 203 and the two first concave surfaces 202 provided in the mold 201 and curing them. A cavity for molding the phosphorescent part 23 (first phosphorescent part 23a and second phosphorescent part 23b) and the reflective layer 24 is formed by the two first concave surfaces 202, and the base part 22 is molded by the second concave surface 203. A cavity is formed. In the present embodiment, the mold 201 is made of silicone, and the phosphor 21 is manufactured by casting.

  In order to manufacture the phosphor 21, first, a phosphorescent pigment and a colorant are mixed with an epoxy resin (polymer compound). Two types of polymer compounds in which different types of phosphorescent pigments are mixed are prepared. Next, the polymer compound in which one phosphorescent pigment and the colorant were mixed was poured into one first concave surface 202 (right side of FIG. 3B) of the mold 201, and the other phosphorescent pigment and the colorant were mixed. The polymer compound is poured into the other first concave surface 202 (left side of FIG. 3B) (phosphorescent part forming step). The polymer compound that forms the reflective layer 24 is applied to the place where the polymer compound poured into the first concave surface 202 has hardened and contracted (the place where the polymer compound is recessed and lowered with respect to the boundary with the second concave surface 203). (Reflective layer placement step). In the present embodiment, the reflective layer 24 (white reflective layer) is formed of a white paint in which a titanium resin powder is mixed with a polyester-based resin or the like.

  After the white paint is cured, a transparent epoxy resin (polymer compound) is poured into the second concave surface 203 of the mold 201 (base part molding step). The base portion 22 is bonded to the reflective layer 24 by the curing of the polymer compound poured into the second concave surface 203 (adhesion step). After the polymer compound is cured, the base portion 22, the phosphorescent portion 23 and the reflective layer 24 are removed from the mold 201 to obtain the phosphorescent body 21.

  According to the method for manufacturing the phosphorescent body 21 described above, the reflective layer 24 is disposed on the back surface of the phosphorescent portion 23, and the reflective layer 24 is sandwiched between the phosphorescent portion 23 and the base portion 22. As a result, phosphorescence due to the phosphorescent pigment is reflected to the front side (opposite side of the base portion 22), so that the afterglow luminance of the phosphorescent portion 23 can be improved in addition to the effects obtained in the first embodiment.

  In addition, since the polymer compound poured into the first concave surface 202 is cured and contracted (in the first concave surface 202), the polymer compound (white paint) that forms the reflective layer 24 is applied. It is possible to make it difficult for the white paint to protrude around 23. As a result, it is possible to prevent the appearance of the phosphor 21 from being deteriorated due to the white paint (reflective layer) that protrudes around the phosphorescent unit 23.

  In addition, since the base part 22 is formed by the epoxy resin having a weak water repellency compared with the silicone type, the phosphorescent body 21 can easily form an adhesive layer by applying an adhesive to the back surface of the base part 22. it can. Thereby, the application example of the attachment means of the luminous body 21 with respect to a target object (not shown) can be increased, and the application range of the luminous body 21 can be expanded.

  Moreover, since the phosphorescence part 23 (the 1st phosphorescence part 23a and the 2nd phosphorescence part 23b) is divided and formed in the several places (2 places in this Embodiment) of the front surface of the base | substrate part 22, the design property of the phosphorescence body 21 is formed. Can be improved. The phosphorescent portion 23 can be formed at an arbitrary position by appropriately designing the mold 201. Furthermore, since the 1st luminous part 23a and the 2nd luminous part 23b are set so that a mutually different color phosphorescence may be emitted, the design property of the luminous body 21 can further be improved.

  In the present embodiment, the case where the reflective layer 24 is formed by applying a white paint has been described. However, the present invention is not necessarily limited to this, and as in the case where the base portion 22 and the phosphorescent portion 23 are formed, a high It is naturally possible to form the reflective layer 24 by pouring molecular compounds. In addition, it is naturally possible to form the reflective layer 24 by arranging and sandwiching a white sheet (white formed material) prepared in advance between the first phosphorescent portion 23a and the second phosphorescent portion 23b and the base portion 22. is there.

  Next, a third embodiment will be described with reference to FIG. In 1st Embodiment and 2nd Embodiment, the case where the base parts 12 and 22 made from a high molecular compound were formed by mold shaping was demonstrated. On the other hand, in 3rd Embodiment, the case where the separately prepared base part 32 is adhere | attached on the luminous part 33 and the luminous body 31 is manufactured is demonstrated. FIG. 4A is a perspective view of the phosphorescent body 31 according to the third embodiment, and FIG. 4B is a cross-sectional view of the mold 301 and the phosphorescent portion 33 for explaining the manufacturing process of the phosphorescent body 31.

  As shown in FIG. 4A, the phosphorescent body 31 has a base portion 32 formed in a substantially rectangular shape when viewed from the front, and is stacked on the base portion 32 and protrudes to the front side with respect to the base portion 32. And a phosphorescent unit 33 in which a graphic symbol (arrow) is formed. In the present embodiment, the base portion 32 is made of a flexible cloth, and a phosphorescent pigment and a colorant are mixed with the silicone rubber (polymer compound) constituting the phosphorescent portion 33. Since the phosphorescent pigment is the same as that described in the first embodiment, the description thereof is omitted.

  Next, with reference to FIG.4 (b), the manufacturing method of the phosphor 31 is demonstrated. The phosphorescent body 31 is manufactured by pouring a polymer compound into a concave surface 302 provided in the mold 301 and curing it to form the phosphorescent portion 33 and bonding the base portion 32 to the phosphorescent portion 33. A cavity for molding the phosphorescent portion 33 is formed by the concave surface 302. In the present embodiment, the forming die 301 is made of an aluminum alloy (made of metal), and the phosphor 31 is manufactured by casting.

  In order to manufacture the phosphorescent body 31, first, a phosphorescent pigment and a colorant are mixed with silicone (polymer compound). Next, a liquid polymer compound in which the phosphorescent pigment and the colorant are mixed is poured into the concave surface 302 of the mold 301 (phosphorescent part molding step). When the polymer compound poured into the concave surface 302 is cured and shrunk (where it is dented and becomes lower than the height of the upper surface of the mold 301), a transparent polymer compound (in this embodiment, phosphorescent light is stored). (Silicone without pigments and colorants).

  Before the transparent polymer compound poured into the concave surface 302 is cured, the base portion 32 (made of cloth) is placed on the upper surface of the mold 301 to bring the polymer compound in the concave surface 302 into contact with the base portion 32. Silicone (liquid polymer compound) penetrates between the fibers of the base portion 32. By the curing of the polymer compound, the phosphorescent portion 33 and the base portion 32 are bonded mainly by the anchor effect (bonding step). After the phosphorescent part 33 and the base part 32 are bonded, the phosphorescent part 33 is removed from the mold 301 to obtain the phosphor 31.

  According to the method for manufacturing the phosphorescent body 31 described above, the phosphorescent part 33 is bonded to the base part 32 by curing of the polymer compound poured into the mold 301 (concave surface 302). By curing the polymer compound constituting the phosphorescent part 33 and bonding the base part 32 simultaneously, the polymer compound constituting the phosphorescent part 33 is cured, and then the phosphorescent part 33 is adhered to the base part 32. Compared with the case, the manufacturing process of the phosphor 31 can be shortened.

  In addition, after the shrinkage of the polymer compound mixed with the phosphorescent pigment, a transparent polymer compound is poured into the concave surface 302 and the polymer compound in the concave surface 302 is brought into contact with the base portion 32. The inner polymer compound can be reliably brought into contact. In addition, since the shrinkage (so-called sink) of the polymer compound in the concave surface 302 can be compensated, it is possible to prevent the bonding strength between the phosphorescent portion 33 and the base portion 32 from being reduced due to the shrinkage of the polymer compound in the concave surface 302. . Further, even when the polymer compound protrudes around the phosphorescent portion 33 and hardens, the appearance of the phosphor 31 can be prevented from deteriorating because the polymer compound is transparent.

  In addition, since the cloth base part 32 is fixed to the back surface of the base part 33 and the size of the base part 32 in the front view is set larger than that of the phosphorescent part 33 in the front view, the cloth base part 32 is made of cloth on the surface of clothes or the like (target object). The base portion 32 can be sewn. In addition, it is also possible to affix the base | substrate part 32 to the surface of clothes etc. (target object) by providing the back surface of the base | substrate part 32 with the heat bonding layer fuse | melted with heat, such as an iron.

  The base portion 32 is formed of a flexible member (made of cloth), and the phosphorescent portion 33 is formed of a silicone polymer compound. The phosphorescent portion 33 is bonded to the base portion 32 by the curing of the silicone polymer compound. Since the silicone polymer compound penetrates between the fibers of the base portion 32 (cloth) and is cured, the phosphorescent portion 33 is firmly bonded to the base portion 32 by the anchor effect. Further, since the silicone polymer compound becomes rubber after curing, the flexibility of the base portion 32 is also maintained. As a result, the flexibility of the base part 32 to which the phosphorescent part 33 is bonded can be maintained.

  Note that the adhesion mechanism between the silicone polymer compound and the base portion 32 is not limited to the anchor effect. Depending on the type of the base portion 32, it is naturally possible to bond the surface of the base portion 32 and the phosphorescent portion 33 by a chemical reaction.

  The present invention has been described above based on the embodiments. However, the present invention is not limited to the above embodiments, and various improvements and modifications can be made without departing from the spirit of the present invention. It can be easily guessed. For example, the shapes and sizes of the base parts 12, 22, 32 and the phosphorescent parts 13, 23, 33 are appropriately designed according to the purpose of the phosphorescent bodies 11, 21, 31.

  In the first embodiment, the case where the phosphorescent body 11 is molded using a polymer compound made of condensation type one-component silicone (modified silicone) is described. However, other polymer compounds may be used. Of course it is possible. Examples of other polymer compounds include addition type silicones, polyurethane resins, epoxy resins, polyester resins, acrylic resins, and ultraviolet curable resins. In addition, the polymer compound is not limited to a one-component (one-component) resin, and it is naturally possible to use a multi-component resin such as a two-component resin.

  In consideration of the material and shape of the phosphor 11 and the durability of the mold 101, the material of the mold 101 can be set as appropriate. In addition, as in the first embodiment, other polymer compounds can naturally be employed for the polymer compounds in the second embodiment and the third embodiment. Note that the first embodiment and the second embodiment may be vacuum casting in which casting is performed under reduced pressure.

Of course it is possible. Examples of other molding means include injection molding, hollow molding, and compression molding. When the phosphors 11 and 21 are manufactured by injection molding, hollow molding, or compression molding, metal molds 101 and 201 are used and combined with another mold to form a cavity.

  When manufacturing phosphorescent bodies 11 and 21 by injection molding or hollow molding, a master batch of polymer compound (synthetic resin, synthetic rubber, etc.) and phosphorescent pigment (about half the target value to be finally kneaded) are mixed Etc., and knead using an extruder or the like while heating to a predetermined temperature. Next, the obtained kneaded product and the phosphorescent pigment (remaining amount to be finally kneaded) are mixed using a mixer or the like, and kneaded using an extruder or the like while being heated to a predetermined temperature.

  If the phosphorescent pigment is kneaded at once without dividing into multiple times, the fluidity when kneading the master batch of the polymer compound and the phosphorescent pigment is lowered, and the dispersibility of the phosphorescent pigment is lowered. There is a tendency to In contrast, the fluidity can be improved by kneading the phosphorescent pigment in a plurality of times, and the dispersibility of the phosphorescent pigment can be improved. As a result, it is possible to prevent the phosphorescent pigment from being unevenly distributed in a part of the phosphorescent portions 13 and 23. Then, the polymer compound heated to the softening temperature is poured into a mold by applying an injection pressure, filled into a cavity, and molded.

  When manufacturing phosphorescent body by compression molding, mix powdery (granular) polymer compound (mainly thermosetting resin) and phosphorescent pigment, pour them into the mold cavity, then heat Then, it is cured and molded by applying pressure.

  In the said 1st Embodiment, although the phosphor 1 as a protective device (safety goods) which prevents that the end part of the pipe P or a reinforcing bar becomes exposed was demonstrated, it is not necessarily restricted to this, The support body 3 Of course, it is possible to use the phosphorescent body as a guide plate, a sign, or the like by appropriately designing the shape and size of the lamp.

  Further, since the phosphors 11, 21, 31 described in the above embodiment can be formed into arbitrary shapes, the phosphors 11, 21, 31 are made of toys such as mascots, pendants, key holders, accessories such as daily goods, name tags, etc. Of course, building members such as flooring and curbs, and civil engineering members are possible.

  In the said embodiment, although the case where the one phosphorescence part 13,23,33 was arrange | positioned on the surface of the base | substrate parts 12,22,32 was demonstrated, it is not necessarily restricted to this, and physically separated 2 It is naturally possible to provide the above phosphorescent part on the surface of the base part.

  In the said 1st Embodiment, although the case where the support body 3 was formed in plate shape (planar shape) was demonstrated, it is not necessarily restricted to this, A lump shape (three-dimensional shape) according to the form of a luminous body It is naturally possible to form.

  Moreover, although the case where the concave portion 3a is formed through the support body 3 has been described, the present invention is not necessarily limited to this. When the support body is formed in a lump shape, the concave portion is formed in a depression shape on the surface of the support body. Of course, it is possible to make it possible to attach a phosphorescent body to the recess.

  In the said 1st Embodiment and 2nd Embodiment, about the case where the phosphorescence body 11 and 21 is manufactured by joining (adhering) the phosphorescence part 13 and 23 and the base | substrate parts 12 and 22 with one shaping | molding die 101,201. explained. However, the present invention is not necessarily limited to this, and it is possible to make the mold for molding the phosphorescent parts 13 and 23 different from the mold for joining (adhering) the phosphorescent parts 13 and 23 to the base parts 12 and 22. It is.

  In this case, first, the phosphorescent portions 13 and 23 are molded by one molding die (not shown). In this case, various molding methods such as cast molding, injection molding, and compression molding can be employed. Thereafter, the molded phosphorescent portions 13 and 23 are arranged (temporarily fixed) on the cavity inner surface of another mold (not shown) (phosphorescent portion arranging step). Next, a polymer compound is poured into another mold (cavity) in which the phosphorescent portions 13 and 23 are arranged, and the phosphorescent portions 13 and 23 are bonded to the base portions 12 and 22 while the base portions 12 and 22 are molded. (Phosphorescent part adhesion process). In this case, various molding methods such as cast molding, injection molding, compression molding, and the like can be employed for molding the base portions 12 and 22. As described above, the first embodiment also applies when the mold for molding the phosphorescent parts 13 and 23 is different from the mold for joining (adhering) the phosphorescent parts 13 and 23 and the base parts 12 and 22. Or the effect acquired by 2nd Embodiment is realizable.

  In addition, the phosphorescent portions 13 and 23 are not molded by cast molding, injection molding, compression molding, or the like, but a phosphorescent material such as a phosphorescent sheet containing a phosphorescent pigment or a ceramic plate (a substrate made of an inorganic material) having a property of emitting phosphorescence ( Naturally, it is possible to prepare and use a “light-storing member” hereinafter in a predetermined outer shape. In that case, first, a phosphorescent member (phosphorescent portion) prepared in a predetermined shape is arranged on the inner surface of the cavity of the mold (phosphorescent portion arranging step). Next, the polymer compound is poured into a mold (in the cavity) in which the phosphorescent member (phosphorescent part) is arranged, and the phosphorescent part is bonded to the base part while the base part is molded (phosphorescent part bonding step). In this case as well, various molding methods such as cast molding, injection molding, compression molding, and the like can be adopted for molding the base portion, and the effects obtained in the first embodiment or the second embodiment can be realized.

  It is naturally possible to provide an adhesive layer on the back surface of the phosphorescent member (phosphorescent portion). As the adhesive layer, a heat-sensitive or pressure-sensitive polymer compound suitable for the polymer compound material is appropriately selected. It is naturally possible to provide a reflective layer (white reflective layer) on the back surface of the phosphorescent member (phosphorescent portion). As the reflection layer, a coating layer formed on the back surface of the phosphorescent member (phosphorescent portion) by applying a white paint, or a white sheet disposed on the back surface of the phosphorescent member (phosphorescent portion) can be used. It is naturally possible to provide an adhesive layer on the white sheet (reflective layer).

  In the third embodiment, the case where the base portion 32 is made of cloth has been described. However, the present invention is not necessarily limited to this, and other materials and members can naturally be used. Other materials and components include, for example, sheets and wallpaper made of paper or synthetic resin; leather (natural leather, artificial leather); synthetic resin, glass, metal plate; metal or synthetic resin mesh Tile (made of inorganic material) and the like. Of course, a retroreflective plate made of synthetic resin or the like can be used as the base portion 32. Since various materials and members can be employed as the base portion 32, the usage of the phosphorescent body 31 can be expanded.

  In addition, when a thing having meshes (gap between fibers or wires) such as paper, leather, etc. (fiber aggregate) or nets is adopted as the base portion 32, the polymer compound is filled in the mesh. The anchor effect is obtained by curing. Silicone (silicone rubber) is a difficult-to-adhere material, but the adhesive strength between the base portion 32 and the phosphorescent portion 33 can be improved by utilizing the anchor effect.

  In the third embodiment, the case where the base portion 32 is bonded simultaneously with the curing of the phosphorescent portion 33 has been described. However, the present invention is not necessarily limited thereto, and the phosphorescent portion 33 is molded (cured) and then bonded. It is naturally possible to bond the phosphorescent part 33 to the base part 32 using an agent or the like. In that case, in order to improve the adhesive strength between the base part 32 and the phosphorescent part 33, the base part 32 and the phosphorescent part 33 can be subjected to a primer treatment.

  Moreover, it is naturally possible to provide the reflection layer 24 described in the second embodiment on the phosphors 11 and 31 described in the first and third embodiments. By providing the reflective layer 24 on the back surfaces of the light storage units 13 and 33, the afterglow luminance of the light storage units 13 and 33 can be improved. Instead of providing the reflection layer 24, it is naturally possible to make the base portions 12 and 32 white and reflect the phosphorescence of the phosphorescent portions 13 and 33 by the base portions 12 and 32.

  The thickness of the phosphorescent portions 13, 23 and 33 (including the phosphorescent member) is 0.5 mm to 10 cm, depending on the particle size of the phosphorescent pigment and the color (background color) and size of the base portions 12, 22, and 32. Are preferably used. This is to make the afterglow luminance of the phosphorescent units 13, 23, and 33 (including the phosphorescent member) less susceptible to the colors of the base units 12, 22, and 32.

  In the present embodiment, the case where the phosphorescent units 13, 23, and 33 contain sulfur-based or oxide-based phosphorescent pigments has been described. However, the present invention is not necessarily limited to this, and absorbs energy of excitation light from the outside. Thus, it is naturally possible to employ other phosphorescent pigments that emit phosphorescence. Moreover, although the case where the luminous parts 13, 23, and 33 contain a colorant has been described, the colorant is not necessarily required.
