Description

本発明は、水素ガスを検知する水素ガス検知テープに関する。   The present invention relates to a hydrogen gas detection tape that detects hydrogen gas.

水素ステーション、水素ガス製造プラント、水素ガス利用プラント等の水素ガスを取り扱う設備では、安全性を確保するために、水素ガスの漏洩を検知する水素ガス検知センサが設置されている。   In facilities that handle hydrogen gas, such as hydrogen stations, hydrogen gas production plants, and hydrogen gas utilization plants, a hydrogen gas detection sensor that detects leakage of hydrogen gas is installed to ensure safety.

一般に、水素ステーションなどにおいては、定位置に設置された水素ガス検知センサによって、極めて低濃度の水素ガスが漏洩した場合であっても、その漏洩を検知することができ、さらに、その監視もできる。また、水素ガス検知センサによって所定濃度以上の水素ガスの漏洩が検知されると、自動的にシステムがシャットダウンし、さらなる漏洩の防止が図られている。   In general, in a hydrogen station or the like, even when a very low concentration of hydrogen gas is leaked by a hydrogen gas detection sensor installed at a fixed position, the leak can be detected and further monitored. . Further, when the hydrogen gas detection sensor detects leakage of hydrogen gas having a predetermined concentration or more, the system is automatically shut down to prevent further leakage.

しかし、極めて低濃度の水素ガスが検知された場合に、その漏洩箇所を詳細に特定するためには、さらに、操作員が配管や機器の設置場所に赴き、携帯型の水素検知器などを用いて漏洩箇所を特定し、その対応措置を行う必要があり、簡便に漏洩箇所を特定する手段がなかった。   However, if an extremely low concentration of hydrogen gas is detected, an operator can go to the installation location of the piping and equipment and use a portable hydrogen detector, etc., in order to pinpoint the location of the leak. Therefore, it was necessary to identify the leak location and take countermeasures, and there was no simple way to identify the leak location.

これに関連する技術として、水素ガスと反応することで変色する水素ガス検知テープを、配管や容器等の水素ガスの漏洩が生じ得る箇所に貼付する技術（例えば、特許文献１）が開発されている。   As a technology related to this, a technology (for example, Patent Document 1) has been developed in which a hydrogen gas detection tape that changes color by reacting with hydrogen gas is attached to a location where leakage of hydrogen gas such as a pipe or container may occur. Yes.

ところで、上記水素ガスを取り扱う設備において、配管や容器は暗所に設置されることが多い。このため、上記特許文献１の水素ガス検知テープでは、テープ自体の存在を確認したり、テープの変色を確認したりするために、配管や容器が収容される空間全体を照明で照らしたり、テープ自体をライトで照らしたりする必要がある。   By the way, in the facility for handling the hydrogen gas, pipes and containers are often installed in a dark place. For this reason, in the hydrogen gas detection tape of the above-mentioned patent document 1, in order to confirm the existence of the tape itself or to confirm the discoloration of the tape, the entire space in which the pipes and containers are accommodated is illuminated with illumination, or the tape It is necessary to light itself.

本発明は、このような課題に鑑み、視認性を向上させることが可能な水素ガス検知テープを提供することを目的としている。   In view of such a problem, an object of the present invention is to provide a hydrogen gas detection tape capable of improving visibility.

上記課題を解決するために、本発明の水素ガス検知テープは、水素ガスの接触により変色する水素検知剤および蓄光剤を含む。   In order to solve the above problems, the hydrogen gas detection tape of the present invention includes a hydrogen detection agent and a phosphorescent agent that change color when contacted with hydrogen gas.

また、前記水素検知剤が含まれる水素検知層と、前記蓄光剤が含まれる蓄光層と、を備えるとしてもよい。   Moreover, you may provide the hydrogen detection layer in which the said hydrogen detection agent is contained, and the luminous layer in which the said luminous agent is contained.

また、粘着層を備えるとしてもよい。   Further, an adhesive layer may be provided.

本発明によれば、視認性を向上させることが可能となる。   According to the present invention, it is possible to improve visibility.

（第１の実施形態：水素ガス検知テープ１００）
図１は、第１の実施形態にかかる水素ガス検知テープ１００を説明する図であり、図１（ａ）は水素ガス検知テープ１００の平面図を示し、図１（ｂ）は図１（ａ）のＩｂ−Ｉｂ線断面の拡大図を示す。なお、図１（ｂ）中、水素検知剤１１２を黒い丸で示し、蓄光剤１１４を白い丸で示すが、理解を容易にするために、実際より大きく記載している。 (First embodiment: hydrogen gas detection tape 100)
1A and 1B are diagrams for explaining a hydrogen gas detection tape 100 according to the first embodiment. FIG. 1A is a plan view of the hydrogen gas detection tape 100, and FIG. ) Is an enlarged view of a cross section taken along line Ib-Ib. In FIG. 1B, the hydrogen detection agent 112 is indicated by a black circle and the phosphorescent agent 114 is indicated by a white circle. However, in order to facilitate understanding, the hydrogen detection agent 114 is shown larger than the actual size.

図１に示すように、水素ガス検知テープ１００は、検知層１１０と、粘着層１２０とを含んで構成される。   As shown in FIG. 1, the hydrogen gas detection tape 100 includes a detection layer 110 and an adhesive layer 120.

検知層１１０は、水素検知剤１１２と、蓄光剤１１４とが、樹脂１１６に分散された層である。水素検知剤１１２は、水素ガスが接触すると変色する物質であり、例えば、酸化パラジウム、酸化パラジウム水化物、酸化タングステン等、既存の物質を利用することができる。   The detection layer 110 is a layer in which a hydrogen detection agent 112 and a phosphorescent agent 114 are dispersed in a resin 116. The hydrogen detection agent 112 is a substance that changes color when contacted with hydrogen gas. For example, an existing substance such as palladium oxide, palladium oxide hydrate, or tungsten oxide can be used.

蓄光剤１１４は、光エネルギー（可視光、紫外線等を含む電磁波のエネルギー）を蓄えて発光する物質であり、例えば、硫化物系の蓄光性蛍光体（例えば硫化亜鉛）、アルミン酸塩系蓄光性蛍光体（例えばアルミン酸ストロンチウム）等、既存の物質を利用することができる。   The phosphorescent agent 114 is a substance that stores light energy (electromagnetic energy including visible light, ultraviolet rays, etc.) and emits light. For example, a sulfide-based phosphorescent phosphor (for example, zinc sulfide), an aluminate-based phosphorescent material. Existing materials such as phosphors (eg, strontium aluminate) can be used.

樹脂１１６は、例えば、ポリイソシアネート化合物とポリオール樹脂とを主成分とする２液型ウレタン、アクリル樹脂、アルキド樹脂、ポリウレタン樹脂等で構成される。   The resin 116 is composed of, for example, a two-component urethane, an acrylic resin, an alkyd resin, a polyurethane resin, or the like mainly composed of a polyisocyanate compound and a polyol resin.

粘着層１２０は、水素ガスが漏洩し得る箇所（もしくは、その近傍）に検知層１１０を固定するための層であり、検知層１１０の一方の面（図１中、Ｚ軸方向の一方の面）に当接して設けられる。粘着層１２０は、例えば、非架橋型粘着性樹脂組成物や架橋硬化型粘着性樹脂組成物で構成される。なお、非架橋型粘着性樹脂組成物は、例えば、塩化ビニル樹脂、ポリウレタン樹脂、ポリエステル樹脂、ゴム、ポリアミド樹脂、酢酸ビニル樹脂、アクリル樹脂、エチレン酢酸ビニル共重合体、塩化ビニル酢酸ビニル共重合体であり、架橋硬化型粘着性樹脂組成物は、尿素樹脂、メラミン樹脂、ポリイソシアネート化合物等の硬化剤をエポキシ樹脂、フェノール樹脂、アクリル樹脂、ポリエステル樹脂等の基体樹脂に混合してなる組成物である。   The adhesive layer 120 is a layer for fixing the detection layer 110 at a location (or the vicinity thereof) where hydrogen gas can leak, and one surface of the detection layer 110 (one surface in the Z-axis direction in FIG. 1). ). The adhesive layer 120 is composed of, for example, a non-crosslinked adhesive resin composition or a crosslinked curable adhesive resin composition. The non-crosslinking type adhesive resin composition includes, for example, vinyl chloride resin, polyurethane resin, polyester resin, rubber, polyamide resin, vinyl acetate resin, acrylic resin, ethylene vinyl acetate copolymer, vinyl chloride vinyl acetate copolymer. The crosslink curable adhesive resin composition is a composition obtained by mixing a curing agent such as urea resin, melamine resin, or polyisocyanate compound with a base resin such as epoxy resin, phenol resin, acrylic resin, or polyester resin. is there.

以上説明したように、本実施形態にかかる水素ガス検知テープ１００によれば、蓄光剤１１４を有する構成により、水素ガス検知テープ１００自体、および、水素検知剤１１２の視認性を向上させることができる。したがって、水素ガス検知テープ１００自体の存在の確認作業が容易になるとともに、水素検知剤１１２の変色の有無を容易に確認することが可能となる。   As described above, according to the hydrogen gas detection tape 100 according to the present embodiment, the configuration having the phosphorescent agent 114 can improve the visibility of the hydrogen gas detection tape 100 itself and the hydrogen detection agent 112. . Therefore, it becomes easy to confirm the presence of the hydrogen gas detection tape 100 itself, and it is possible to easily confirm the presence or absence of discoloration of the hydrogen detection agent 112.

なお、水素ガス検知テープ１００は、水素ガスが漏洩し得る箇所（配管の継手部分等）の上方に貼付されるとよい。水素ガスは空気より軽いため、漏洩した水素は、漏洩箇所より上方に移動する。したがって、水素ガスが漏洩し得る箇所の上方に水素ガス検知テープ１００を貼付することにより、迅速かつ確実に水素ガスの漏洩を検知することができる。   In addition, the hydrogen gas detection tape 100 is good to affix above the location (the joint part etc. of piping) where hydrogen gas may leak. Since hydrogen gas is lighter than air, the leaked hydrogen moves upward from the leak location. Therefore, by sticking the hydrogen gas detection tape 100 above the portion where hydrogen gas can leak, the leakage of hydrogen gas can be detected quickly and reliably.

（変形例）
上記実施形態において、水素検知剤１１２と蓄光剤１１４とが同一の検知層１１０に含まれる水素ガス検知テープ１００について説明した。しかし、水素検知剤１１２を含む層と、蓄光剤１１４を含む層とが別々に設けられていてもよい。 (Modification)
In the above embodiment, the hydrogen gas detection tape 100 in which the hydrogen detection agent 112 and the phosphorescent agent 114 are included in the same detection layer 110 has been described. However, the layer containing the hydrogen detection agent 112 and the layer containing the phosphorescent agent 114 may be provided separately.

図２は、変形例にかかる水素ガス検知テープ２００を説明する図であり、図２（ａ）は第１の変形例にかかる水素ガス検知テープ２００の平面図を示し、図２（ｂ）は図２（ａ）のＩＩｂ−ＩＩｂ線断面の拡大図を示し、図２（ｃ）は第２の変形例にかかる水素ガス検知テープ２５０の平面図を示し、図２（ｄ）は図２（ｃ）のＩＩｄ−ＩＩｄ線断面の拡大図を示す。なお、図２（ｂ）、（ｄ）中、水素検知剤１１２を黒い丸で示し、蓄光剤１１４を白い丸で示すが、理解を容易にするために、実際より大きく記載している。   FIG. 2 is a diagram for explaining a hydrogen gas detection tape 200 according to a modification. FIG. 2 (a) is a plan view of the hydrogen gas detection tape 200 according to the first modification, and FIG. 2A is an enlarged view of a section taken along line IIb-IIb of FIG. 2A, FIG. 2C is a plan view of a hydrogen gas detection tape 250 according to a second modification, and FIG. The enlarged view of the IId-IId sectional view of c) is shown. In FIGS. 2B and 2D, the hydrogen detection agent 112 is indicated by a black circle and the phosphorescent agent 114 is indicated by a white circle. However, in order to facilitate understanding, the hydrogen detection agent 112 is illustrated larger than the actual one.

図２（ａ）、（ｂ）に示すように、第１の変形例にかかる水素ガス検知テープ２００は、水素検知層２１０と、蓄光層２２０と、粘着層１２０とを含んで構成される。水素検知層２１０は、水素検知剤１１２が樹脂１１６に分散された層である。蓄光層２２０は、蓄光剤１１４が樹脂１１６に分散された層である。水素ガス検知テープ２００において、水素検知層２１０と蓄光層２２０とは隣接して（図２（ａ）、（ｂ）中、Ｙ軸方向に隣接して）設けられている。   As shown in FIGS. 2A and 2B, the hydrogen gas detection tape 200 according to the first modification includes a hydrogen detection layer 210, a light storage layer 220, and an adhesive layer 120. The hydrogen detection layer 210 is a layer in which the hydrogen detection agent 112 is dispersed in the resin 116. The phosphorescent layer 220 is a layer in which the phosphorescent agent 114 is dispersed in the resin 116. In the hydrogen gas detection tape 200, the hydrogen detection layer 210 and the phosphorescent layer 220 are provided adjacent to each other (adjacent in the Y-axis direction in FIGS. 2A and 2B).

第１の変形例にかかる水素ガス検知テープ２００では、水素検知剤１１２を含む水素検知層２１０に隣接して、蓄光層２２０が設けられる構成により、水素検知剤１１２の視認性を向上させることが可能となる。   In the hydrogen gas detection tape 200 according to the first modification, the visibility of the hydrogen detection agent 112 can be improved by the configuration in which the phosphorescent layer 220 is provided adjacent to the hydrogen detection layer 210 including the hydrogen detection agent 112. It becomes possible.

図２（ｃ）、（ｄ）に示すように、第２の変形例にかかる水素ガス検知テープ２５０は、水素検知層２１０と、蓄光層２２０と、粘着層１２０とを含んで構成される。水素ガス検知テープ２５０において、蓄光層２２０は、水素検知層２１０を囲繞して設けられる。かかる構成により、水素検知剤１１２の視認性をさらに向上させることが可能となる。   As shown in FIGS. 2C and 2D, the hydrogen gas detection tape 250 according to the second modified example includes a hydrogen detection layer 210, a phosphorescent layer 220, and an adhesive layer 120. In the hydrogen gas detection tape 250, the phosphorescent layer 220 is provided surrounding the hydrogen detection layer 210. With this configuration, the visibility of the hydrogen detection agent 112 can be further improved.

（第２の実施形態：水素ガス検知テープ３００）
図３は、第２の実施形態にかかる水素ガス検知テープ３００を説明する図であり、図３（ａ）は水素ガス検知テープ３００の平面図を示し、図３（ｂ）は図３（ａ）のＩＩＩｂ−ＩＩＩｂ線断面の拡大図を示す。なお、図３（ｂ）中、水素検知剤１１２を黒い丸で示し、蓄光剤１１４を白い丸で示すが、理解を容易にするために、実際より大きく記載している。 (Second Embodiment: Hydrogen Gas Detection Tape 300)
FIG. 3 is a diagram for explaining a hydrogen gas detection tape 300 according to the second embodiment. FIG. 3A is a plan view of the hydrogen gas detection tape 300, and FIG. ) Is an enlarged view of a section taken along line IIIb-IIIb. In FIG. 3B, the hydrogen detection agent 112 is indicated by a black circle and the phosphorescent agent 114 is indicated by a white circle. However, in order to facilitate understanding, the hydrogen detection agent 112 is shown larger than the actual size.

図３に示すように、水素ガス検知テープ３００は、水素検知層２１０と、２つの蓄光層２２０と、２つの粘着層１２０とを含んで構成される。水素検知層２１０は、２つの蓄光層２２０の間に設けられる。また、蓄光層２２０における一方の面（図３中、Ｚ軸方向の一方の面）には、粘着層１２０が設けられるが、水素検知層２１０における一方の面には粘着層１２０が配されない。   As shown in FIG. 3, the hydrogen gas detection tape 300 includes a hydrogen detection layer 210, two light storage layers 220, and two adhesive layers 120. The hydrogen detection layer 210 is provided between the two light storage layers 220. Further, the adhesive layer 120 is provided on one surface of the phosphorescent layer 220 (one surface in the Z-axis direction in FIG. 3), but the adhesive layer 120 is not disposed on one surface of the hydrogen detection layer 210.

かかる構成により、水素ガスが漏洩し得る箇所に水素ガス検知テープ３００を貼付した場合に、漏洩した水素ガスは、粘着層１２０を通過することなく、水素検知層２１０に直接導かれることとなる。したがって、水素ガス検知テープ３００は、水素ガス検知テープ３００自体および水素検知剤１１２の視認性の向上に加えて、水素検知層２１０による水素ガスの検知感度を向上させることが可能となる。   With this configuration, when the hydrogen gas detection tape 300 is attached to a location where hydrogen gas can leak, the leaked hydrogen gas is directly guided to the hydrogen detection layer 210 without passing through the adhesive layer 120. Therefore, the hydrogen gas detection tape 300 can improve the detection sensitivity of the hydrogen gas by the hydrogen detection layer 210 in addition to improving the visibility of the hydrogen gas detection tape 300 itself and the hydrogen detection agent 112.

以上、添付図面を参照しながら本発明の好適な実施形態について説明したが、本発明はかかる実施形態に限定されないことは言うまでもない。当業者であれば、特許請求の範囲に記載された範疇内において、各種の変更例または修正例に想到し得ることは明らかであり、それらについても当然に本発明の技術的範囲に属するものと了解される。   As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this embodiment. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

例えば、第１の実施形態における水素ガス検知テープ１００は、検知層１１０のうち、粘着層１２０が設けられる面の逆側の面に、検知層１１０を保護する保護層を備えてもよい。同様に、第１の変形例における水素ガス検知テープ２００、第２の変形例における水素ガス検知テープ２５０は、水素検知層２１０および蓄光層２２０のうち、粘着層１２０が設けられる面の逆側の面に、水素検知層２１０および蓄光層２２０を保護する保護層を備えてもよい。また、第２の実施形態における水素ガス検知テープ３００は、蓄光層２２０のうち粘着層１２０が設けられる面の逆側の面および、当該逆側の面と略面一となる水素検知層２１０の面に保護層を備えてもよい。これにより、検知層１１０、水素検知層２１０、蓄光層２２０を保護することができる。なお、保護層は、透明度が高く、水素の透過率が大きい材料で構成されるとよい。これにより、水素ガス検知テープ１００、２００、２５０、３００の視認性を確保することができ、また、水素ガスの検知感度の低下を抑制することが可能となる。   For example, the hydrogen gas detection tape 100 according to the first embodiment may include a protective layer that protects the detection layer 110 on the surface of the detection layer 110 opposite to the surface on which the adhesive layer 120 is provided. Similarly, the hydrogen gas detection tape 200 in the first modification and the hydrogen gas detection tape 250 in the second modification are on the opposite side of the surface of the hydrogen detection layer 210 and the phosphorescent layer 220 where the adhesive layer 120 is provided. A protective layer that protects the hydrogen detection layer 210 and the phosphorescent layer 220 may be provided on the surface. Moreover, the hydrogen gas detection tape 300 in 2nd Embodiment is the surface of the reverse side of the surface in which the adhesion layer 120 is provided among the luminous layers 220, and the hydrogen detection layer 210 which becomes substantially flush with the surface on the opposite side. A protective layer may be provided on the surface. Thereby, the detection layer 110, the hydrogen detection layer 210, and the luminous layer 220 can be protected. Note that the protective layer is preferably made of a material having high transparency and high hydrogen permeability. Thereby, the visibility of the hydrogen gas detection tapes 100, 200, 250, and 300 can be ensured, and a decrease in the detection sensitivity of hydrogen gas can be suppressed.

また、水素ガス検知テープ１００、２００、２５０、３００が、粘着層１２０を備える構成を例に挙げて説明した。しかし、粘着層１２０は必須の構成ではない。   In addition, the hydrogen gas detection tapes 100, 200, 250, and 300 have been described using the configuration including the adhesive layer 120 as an example. However, the adhesive layer 120 is not an essential configuration.

また、上記第１の実施形態において、検知層１１０と、粘着層１２０とが異なる層で構成される水素ガス検知テープ１００について説明した。しかし、粘着層１２０が水素検知剤１１２および蓄光剤１１４を含んでもよい。また、水素検知剤１１２を含む粘着層１２０と、蓄光剤１１４を含む粘着層１２０とが隣接して設けられてもよい。   Moreover, in the said 1st Embodiment, the hydrogen gas detection tape 100 comprised by the layer from which the detection layer 110 and the adhesion layer 120 differ was demonstrated. However, the adhesive layer 120 may include the hydrogen detection agent 112 and the phosphorescent agent 114. Moreover, the adhesion layer 120 containing the hydrogen detection agent 112 and the adhesion layer 120 containing the luminous agent 114 may be provided adjacent to each other.

また、水素検知層２１０を最上面に、蓄光層２２０を水素検知層２１０の下面に、粘着層１２０を蓄光層２２０の下面とした、各層が分離された構成の水素ガス検知テープとしてもよい。   Alternatively, the hydrogen detection layer 210 may be a top surface, the phosphorescent layer 220 may be a lower surface of the hydrogen detection layer 210, and the adhesive layer 120 may be a lower surface of the phosphorescence layer 220.

また、プラスチック（例えば、アクリル）や、水を通さないシール等（材料は問わない）を水素検知テープの表面に付し、水分から水素検知テープを保護してもよい。   Further, a plastic (for example, acrylic), a water-impervious seal, or the like (regardless of material) may be attached to the surface of the hydrogen detection tape to protect the hydrogen detection tape from moisture.

本発明は、水素ガスを検知する水素ガス検知テープに利用することができる。   The present invention can be used for a hydrogen gas detection tape for detecting hydrogen gas.
