Description

本発明は、例えば避難誘導用の標識等に用いられる蓄光性発光体の製造方法に関するものである。   The present invention relates to a method for manufacturing a luminous phosphor used for, for example, a sign for evacuation guidance.

従来、ホテル、デパート、各種公共施設等、公衆の利用に供される建物内には避難誘導用の標識が設置されており、標識には誘導方向を示す矢印等の図形を表示したものが一般的である。例えば、壁面に設置される標識としては、アルミニウム板からなる基材に白色顔料によって下地層を形成するとともに、下地層の上に蓄光材からなる表示部をスクリーン印刷によって形成し、蓄光材により表示部を発光させるようにしたものが知られている（例えば、特許文献１参照）。
特開２００２−３６６０６５号公報 Conventionally, signs for evacuation guidance have been installed in buildings for public use, such as hotels, department stores, various public facilities, etc., and the signs are usually displayed with a figure such as an arrow indicating the direction of guidance. Is. For example, as a sign placed on the wall surface, a base layer is formed with a white pigment on a base material made of an aluminum plate, and a display portion made of a phosphorescent material is formed on the base layer by screen printing, and displayed by the phosphorescent material. A device in which a part is made to emit light is known (for example, see Patent Document 1).
JP 2002-366065 A

ところで、前記蓄光材は、小粒形（１００μ以下）よりも大粒形（１００μ〜２００μ）の方が発光性が高く、避難誘導標識等に用いる場合に適しているが、スクリーン印刷では、スクリーンの目が細かいため、大粒形の蓄光材を用いて表示部の図形を印刷することは不可能である。そこで、表示部の図形を蓄光層の上に顔料を用いてスクリーン印刷する方法もあるが、大粒形の蓄光材を用いると蓄光層の表面の凹凸が大きくなるため、スクリーン印刷では蓄光層の表面に図形の外観を損なわずに表示部を形成することができなかった。   By the way, as for the phosphorescent material, a large particle shape (100 μm to 200 μm) has a higher light emitting property than a small particle shape (100 μm or less) and is suitable for use as an evacuation guidance sign or the like. However, it is impossible to print the graphic of the display unit using a large-sized phosphorescent material. Therefore, there is a method to screen-print the graphic of the display part on the phosphorescent layer using a pigment, but if a large-grain phosphorescent material is used, the irregularities on the surface of the phosphorescent layer will increase, so screen printing is a surface of the phosphorescent layer. In addition, the display portion could not be formed without impairing the appearance of the figure.

本発明は前記問題点に鑑みてなされたものであり、その目的とするところは、大粒形の蓄光材を用いる場合でも、図形や文字の外観を損なわずに表示部を形成することのできる蓄光性発光体の製造方法を提供することにある。   The present invention has been made in view of the above-mentioned problems, and the object of the present invention is to provide a phosphorescent material capable of forming a display unit without impairing the appearance of figures and characters even when a large-grain phosphorescent material is used. Another object of the present invention is to provide a method for producing a luminescent material.

本発明は前記目的を達成するために、蓄光材からなる平面状の発光部に任意の図形または文字からなる表示部を形成してなる蓄光性発光体の製造方法において、表面に顔料及び蓄光材を保持可能な仮保持部材の表面に前記表示部となる顔料層を形成した後、仮保持部材の顔料層の上に前記発光部となる蓄光層を粒径が１００μ〜１０００μの粒形状の蓄光材を用いて形成し、蓄光層を顔料層と共に仮保持部材から剥離することにより発光部及び表示部を形成するようにしている。 In order to achieve the above-mentioned object, the present invention provides a method for producing a luminous phosphor, in which a planar light-emitting part made of a phosphorescent material is formed with a display part consisting of arbitrary figures or characters, and a pigment and a phosphorescent material on the surface. After forming a pigment layer serving as the display portion on the surface of the temporary holding member capable of holding the light, the phosphorescent layer serving as the light emitting portion is formed on the pigment layer of the temporary holding member so that the particle shape is 100 μm to 1000 μm. The light emitting part and the display part are formed by separating the phosphorescent layer from the temporary holding member together with the pigment layer.

これにより、仮保持部材の表面に顔料層が形成された後、仮保持部材の顔料層の上に蓄光層が形成され、蓄光層が顔料層と共に仮保持部材から剥離されて発光部及び表示部が形成されることから、表示部の図形を蓄光層に直接印刷することなく仮保持部材の表面に印刷することができる。   Thereby, after the pigment layer is formed on the surface of the temporary holding member, the luminous layer is formed on the pigment layer of the temporary holding member, and the luminous layer is peeled off from the temporary holding member together with the pigment layer, and the light emitting unit and the display unit Therefore, the graphic of the display unit can be printed on the surface of the temporary holding member without directly printing on the phosphorescent layer.

本発明によれば、表示部の図形を蓄光層に直接印刷することなく仮保持部材の表面に印刷することができるので、表示部となる図形の外観を損なうことなく大粒形（１００μ〜１０００μ）の蓄光材を用いて発光性能の優れた蓄光性発光体を製造することができる。
According to the present invention, since the graphic of the display unit can be printed on the surface of the temporary holding member without directly printing on the phosphorescent layer, the large particle shape (100 μm to 1000 μm) is obtained without impairing the appearance of the graphic serving as the display unit. it is possible to manufacture an excellent luminous emission of the light-emitting performance using a phosphorescent material.

図１乃至図８は本発明の一実施形態を示すもので、図１は蓄光性発光体の斜視図、図２乃至図７はその製造工程を示す斜視図、図８はその製造工程を示す側面断面図である。   1 to 8 show an embodiment of the present invention, FIG. 1 is a perspective view of a luminous phosphor, FIGS. 2 to 7 are perspective views showing the manufacturing process, and FIG. 8 shows the manufacturing process. It is side surface sectional drawing.

この蓄光性発光体は、平面状の発光部１と、発光部１に形成された表示部２とからなり、建物内に設置される避難誘導用の標識として用いられる。発光部１は粒状の蓄光材をシート状に形成してなり、蓄光材には外部の光を吸収して暗中で発光する周知のものが用いられる。表示部２は避難誘導用の周知の図形からなり、発光部１の表面側に所定色の顔料を用いて形成されている。また、発光部１の裏面側は光反射性の基材３に固定されており、基材３は表面が白色の塩化ビニールシートからなる。   This luminous phosphor is composed of a planar light-emitting part 1 and a display part 2 formed on the light-emitting part 1, and is used as a sign for evacuation guidance installed in a building. The light emitting unit 1 is formed by forming a granular phosphorescent material into a sheet shape, and a known phosphor that absorbs external light and emits light in the dark is used as the phosphorescent material. The display unit 2 is formed of a well-known figure for evacuation guidance, and is formed on the surface side of the light emitting unit 1 using a predetermined color pigment. Moreover, the back surface side of the light emission part 1 is being fixed to the light-reflective base material 3, and the base material 3 consists of a vinyl chloride sheet whose surface is white.

次に、前記蓄光性発光体の製造方法を説明する。まず、図２及び図８(a) に示すように仮保持部材４（例えば厚紙）の一方の面に水溶性の表面層４ａ（例えばデキストリン）を形成したものを用意し、図３及び図８(b) に示すように仮保持部材４の上に表示部２となる図形をスクリーン印刷により印刷して顔料層２ａを形成する。その際、仮保持部材４には表示部２の図形の反転像を印刷する。この後、仮保持部材４における発光部１の形成範囲４ｂに図示しない接着剤を塗布して粒状の蓄光材を接着することにより、図４及び図８(c) に示すように顔料層２ａを含む仮保持部材４の上に発光部１となる蓄光層１ａを形成する。この場合、蓄光材には大粒形（１００μ〜１０００μ）のものを用いる。次に、顔料層２ａ及び蓄光層１ａを保持した仮保持部材４を水に浸漬して表面層４ａを溶融させ、図５及び図８(d) に示すように蓄光層１ａを顔料層２ａと共に仮保持部材４から剥離することにより発光部１及び表示部２を形成する。その際、仮保持部材４には表示部２の図形の反転像が印刷されているため、図６に示すように発光部１の表面には反転していない図形が形成される。そして、図７及び図８(e) に示すように発光部１の裏面側に光反射性の基材３を図示しない両面粘着テープまたは接着剤により貼り付けることにより、蓄光性発光体の製造が完了する。   Next, the manufacturing method of the said luminous luminous body is demonstrated. First, as shown in FIGS. 2 and 8 (a), a temporary holding member 4 (for example, cardboard) having a water-soluble surface layer 4a (for example, dextrin) formed on one surface is prepared. As shown in (b), the figure which becomes the display part 2 is printed on the temporary holding member 4 by screen printing to form the pigment layer 2a. At that time, a reverse image of the graphic of the display unit 2 is printed on the temporary holding member 4. Thereafter, the pigment layer 2a is formed as shown in FIGS. 4 and 8C by applying an adhesive (not shown) to the formation range 4b of the light emitting portion 1 in the temporary holding member 4 and adhering a granular phosphorescent material. On the temporary holding member 4 including, the luminous layer 1a used as the light emission part 1 is formed. In this case, a large particle (100 μm to 1000 μm) phosphorescent material is used. Next, the temporary holding member 4 holding the pigment layer 2a and the phosphorescent layer 1a is immersed in water to melt the surface layer 4a. As shown in FIGS. 5 and 8 (d), the phosphorescent layer 1a is combined with the pigment layer 2a. The light emitting part 1 and the display part 2 are formed by peeling from the temporary holding member 4. At that time, since the reverse image of the graphic of the display unit 2 is printed on the temporary holding member 4, a non-inverted graphic is formed on the surface of the light emitting unit 1 as shown in FIG. Then, as shown in FIG. 7 and FIG. 8 (e), the light-reflective luminous body can be manufactured by attaching the light-reflective substrate 3 to the back surface side of the light-emitting portion 1 with a double-sided adhesive tape or an adhesive (not shown). Complete.

このように、本実施形態によれば、仮保持部材４の表面に表示部２となる顔料層２ａを形成した後、仮保持部材４の顔料層２ａの上に発光部１となる蓄光層１ａを形成し、蓄光層１ａを顔料層２ａと共に仮保持部材４から剥離することにより発光部１及び表示部２を形成するようにしたので、表面に凹凸を有する蓄光層１ａに直接印刷することなく、仮保持部材４の平滑な面に表示部２の図形を印刷することができる。従って、表示部２となる図形の外観を損なうことなく大粒形の蓄光材を用いることができるので、発光性能の優れた蓄光性発光体を製造することができる。   Thus, according to this embodiment, after forming the pigment layer 2a which becomes the display part 2 on the surface of the temporary holding member 4, the luminous layer 1a which becomes the light emitting part 1 on the pigment layer 2a of the temporary holding member 4. Since the light emitting part 1 and the display part 2 are formed by peeling the phosphorescent layer 1a from the temporary holding member 4 together with the pigment layer 2a, without directly printing on the phosphorescent layer 1a having irregularities on the surface The figure of the display unit 2 can be printed on the smooth surface of the temporary holding member 4. Therefore, since a large-grain phosphorescent material can be used without impairing the appearance of the figure serving as the display unit 2, a luminous phosphor having excellent luminous performance can be manufactured.

また、顔料層２ａ及び蓄光層１ａを可溶性の表面層４ａを有する仮保持部材４の表面に形成し、仮保持部材４の表面層４ａを溶融することにより顔料層２ａ及び蓄光層１ａを仮保持部材４から剥離するようにしたので、顔料や蓄光材が仮保持部材４の表面に残ることがなく、顔料層２ａ及び蓄光層１ａを仮保持部材４から確実に分離することができる。   Further, the pigment layer 2a and the phosphorescent layer 1a are formed on the surface of the temporary holding member 4 having the soluble surface layer 4a, and the surface layer 4a of the temporary holding member 4 is melted to temporarily hold the pigment layer 2a and the luminous layer 1a. Since the pigment 4 and the phosphorescent material are not separated from the surface of the temporary holding member 4, the pigment layer 2 a and the luminous layer 1 a can be reliably separated from the temporary holding member 4.

この場合、仮保持部材４の表面層４ａに水溶性の材料を用いるとともに、仮保持部材４を水に浸漬して表面層４ａを溶融するようにしたので、剥離作業を容易に行うことができ、生産効率の向上を図ることができる。   In this case, since the water-soluble material is used for the surface layer 4a of the temporary holding member 4, and the temporary holding member 4 is immersed in water to melt the surface layer 4a, the peeling operation can be easily performed. The production efficiency can be improved.

また、仮保持部材４に表示部２となる図形の反転像を印刷するようにしたので、非対称の図形からなる表示部２を形成する場合でも、所望の向きの図形を容易に形成することができる。   In addition, since the reverse image of the figure that becomes the display unit 2 is printed on the temporary holding member 4, even when the display unit 2 that is an asymmetric figure is formed, it is possible to easily form a figure having a desired orientation. it can.

尚、前記実施形態において基材３、仮保持部材４及び表面層４ａに用いた材料は一例であり、同等のものであれば他の材料を用いることが可能である。また、前記実施形態では、仮保持部材４に接着剤を塗布して蓄光材を付着させることにより蓄光層１ａを形成するようにしたものを示したが、例えば蓄光材と溶剤との混合材を塗布するなど、他の方法により蓄光層１ａを形成するようにしてもよい。更に、前記実施形態では、避難誘導標識として用いられる蓄光性発光体の製造方法を示したが、任意の図形や文字からなる表示部を有するものであれば、本発明は他の用途に用いる蓄光性発光体の製造にも適用することができる。   In addition, the material used for the base material 3, the temporary holding member 4, and the surface layer 4a in the said embodiment is an example, and if it is equivalent, it is possible to use another material. In the above embodiment, the phosphorescent layer 1a is formed by applying an adhesive to the temporary holding member 4 and attaching the phosphorescent material. However, for example, a mixture of a phosphorescent material and a solvent is used. The phosphorescent layer 1a may be formed by other methods such as coating. Furthermore, in the said embodiment, although the manufacturing method of the luminous luminous body used as an evacuation guidance sign was shown, if it has a display part which consists of arbitrary figures and characters, this invention is the luminous phosphor used for another use. The present invention can also be applied to the production of a fluorescent light emitter.
