従来、通常の蓄光式標識板は、JIS Z9107(安全標識板)の蓄光式標識板に記載されているように透明保護層、デザイン表示、蓄光層、白色反射層の構造となっている。
この種蓄光式標識板は、蓄光顔料入りアクリル板の裏面側を接着剤(アクリル系接着剤)で白色アクリル板と接着し、表面側にデザインを印刷した透明保護フィルムを接着して製作していた。
しかし、この様な方法は、作業工程が多く、また接着剤を使用しているため2〜3日の養生期間が必要であるという問題点を有していた。
Conventionally, a normal phosphorescent signboard has a structure of a transparent protective layer, a design display, a phosphorescent layer, and a white reflective layer as described in the JIS Z9107 (safety signboard) phosphorescent signboard.
This kind of phosphorescent signboard is manufactured by adhering the back side of an acrylic plate containing phosphorescent pigment to a white acrylic plate with an adhesive (acrylic adhesive) and adhering a transparent protective film with a design printed on the front side. It was.
However, such a method has a problem that it requires a work period of 2 to 3 days because it has many work steps and uses an adhesive.
これを改善した方法として、透明保護フィルムに蓄光顔料入りアクリル樹脂を塗工し、養生後デザインを印刷した透明保護フィルムを接着する方法があるが、上記方法と同様に工程が多く、接着材の養生期間が必要であるという問題点は改善されていない。
更に改善した方法として、白色反射層と蓄光層を予め注型法で成形しておき、ついでこの蓄光層の上にデザインを印刷した透明保護フィルムを載置し、この上に接着用透明ウレタン材を流し込み一体化する方法が提案された(実用新案登録第3121034号)。
しかし、この方法においても、作業工程が多く、接着剤を使用しているため、接着材の養生期間が必要であるという問題点は改善されていない。
As a method for improving this, there is a method in which an acrylic resin containing a phosphorescent pigment is applied to a transparent protective film, and a transparent protective film on which a design after curing is printed is adhered. The problem of the need for a curing period has not been improved.
As a further improved method, a white reflective layer and a phosphorescent layer are formed in advance by a casting method, and then a transparent protective film having a design printed thereon is placed on the phosphorescent layer, and a transparent urethane material for adhesion is placed thereon. Has been proposed (utility model registration No. 3121034).
However, even in this method, since there are many work steps and an adhesive is used, the problem that an adhesive curing period is required has not been improved.
また、これらに使用する蓄光顔料は、非常に高硬度で、かつ研磨性が高いため樹脂との混合が困難で成形設備を早期に損傷する問題も惹起していた。
そして、上述した何れの製品も、壁面や柱等に取付ける際は、両面粘着テープや接着剤等を使用して取付けていたため、取付けに手間が掛かった。
また、デザインの変更や表示位置の変更を行う場合に、標識板を取外すことが困難であると共に、取外す際に標識板を損傷する危険があった。
更に、標識板を取外した後の壁面や柱に粘着材や接着剤の跡が残り、美観を損ねる問題も招来した。
In addition, when any of the above-described products is attached to a wall surface, a pillar, or the like, since it is attached using a double-sided adhesive tape, an adhesive, or the like, it takes time and effort.
In addition, when changing the design or changing the display position, it is difficult to remove the sign plate, and there is a risk of damaging the sign plate when removing the sign plate.
In addition, a sticking material or adhesive remains on the wall or pillar after the sign board is removed, causing a problem of deteriorating the appearance.

そして、使用する樹脂材としては、ウレタン系樹脂、ポリエステル系樹脂、シリコーン樹脂、アクリル樹脂等が適宜選択して用いられるが、熱硬化性ポリウレタンが特に好ましい。
また、蓄光顔料の平均粒径は、50〜250μmのものが好ましく、特に100μm以上の高輝度仕様であることが望ましい。
The phosphorescent marker plate according to the present invention is a phosphorescent laminate in which a transparent protective layer 1, a
And as a resin material to be used, a urethane-type resin, a polyester-type resin, a silicone resin, an acrylic resin, etc. are selected suitably, and a thermosetting polyurethane is especially preferable.
Further, the average particle diameter of the phosphorescent pigment is preferably 50 to 250 μm, and particularly preferably has a high luminance specification of 100 μm or more.
また、蓄光層2及び白色反射層3にはガラスビーズが混合されることが好ましい。
更に、透明保護層1としては、PET(ポリエチレンテレフタレート)フィルムが用いられる。
また、磁性材料5としては、着磁可能か、磁石に吸着可能であれば良く、フェライト粉末が用いられる。
通常、磁性材料5は、製品完成後に着磁され、鉄製の壁面や柱に取付け可能となる。
また、透明保護層1の蓄光層2側の面に、非常口等の意匠11を施してある。
In addition, glass beads are preferably mixed in the
Furthermore, as the transparent protective layer 1, a PET (polyethylene terephthalate) film is used.
The
Usually, the
In addition, a
ついで、本実施例に係る蓄光式標識板の製造方法について説明する。
まず遠心成形ドラムに透明保護層1を取り付け、次に無黄変ウレタンプレポリマー100部、平均粒形150μmの蓄光顔料100部、平均粒径150μmのガラスビーズ100部、アミン系硬化剤10部を均一に混合した蓄光材を、型温度100℃、回転数100rpmで流し込み、流し込みから10〜15分後無黄変ウレタンプレポリマー30部、白色顔料1部、磁性材料10部、平均粒径150μmのガラスビーズ30部、アミン系硬化剤3部を均一に混合して、遠心成形ドラムの内面に流し込み、白色反射層3を形成、流し込みから20〜30分後に離型する。
ついで、遠心成形ドラムより取り出した成形品をカットした後、カット品を平坦な板に挟んで、100℃で3時間熱処理を施す。
Subsequently, the manufacturing method of the luminous sign board concerning a present Example is demonstrated.
First, the transparent protective layer 1 is attached to the centrifugal molding drum, and then 100 parts of a non-yellowing urethane prepolymer, 100 parts of a luminous pigment having an average particle size of 150 μm, 100 parts of glass beads having an average particle diameter of 150 μm, and 10 parts of an amine-based curing agent are added. A uniformly mixed phosphorescent material was poured at a mold temperature of 100 ° C. and a rotation speed of 100 rpm, and after 10 to 15 minutes from casting, 30 parts of a non-yellowing urethane prepolymer, 1 part of a white pigment, 10 parts of a magnetic material, and an average particle size of 150 μm 30 parts of glass beads and 3 parts of an amine-based curing agent are uniformly mixed and poured into the inner surface of the centrifugal molding drum to form a white
Next, after the molded product taken out from the centrifugal molding drum is cut, the cut product is sandwiched between flat plates and heat treated at 100 ° C. for 3 hours.
尚、ここで、蓄光層2が形成された後であっても、完全に硬化するまでの間に、次の白色反射層を流し込むことが好ましい。
これは、未反応の反応基が存在している間に行うことにより、層間の接合が強固になるからである。
本実施例のウレタン材は、注型ウレタン材であり、プレポリマーと言われる反応基(−NCO)を持つ主材と硬化剤(アミン系)とが反応してポリウレタンになるものである。
Here, even after the
This is because the bonding between the layers is strengthened by performing it while there are unreacted reactive groups.
The urethane material of this example is a cast urethane material, which is a polyurethane formed by a reaction between a main material having a reactive group (—NCO) called a prepolymer and a curing agent (amine type).
第1の混合物(白色反射材)を構成するウレタン材においては、主材と硬化剤とが混合され、注入された後、硬化することとなるが、未反応の反応基が存在している間に第2の混合物(蓄光材)が注入されることにより、第1混合物の未反応の反応基と第2混合物とが反応する。
これにより、第1混合物から成形された蓄光層2と、第2混合物とから形成された白色反射層が、より強固に一体化した成形物が成形されることとなる。
In the urethane material constituting the first mixture (white reflective material), the main material and the curing agent are mixed and injected, and then cured, while an unreacted reactive group exists. When the second mixture (phosphorescent material) is injected into the unreacted reactive group of the first mixture and the second mixture react.
As a result, a molded product in which the
また、熱可塑性ポリウレタン材を使用しているため、蓄光式標識板が一定の柔軟性を備えており、平面以外の取付け面に対しても、取り付けが可能である。
具体的には、地下鉄、地下街の円柱に取付ける避難誘導標識や、その他曲率の異なる相手面に対しても柔軟に馴染むため、使用することが出来る。
更に、白色反射層に磁性材料が存在するため、両面テープや接着剤を使用しなくとも、蓄光式標識板を必要な箇所に簡単に取付けることが可能である。
また、白色反射層3と、樹脂材に蓄光顔料を混合した蓄光層2とが順次積層されており、これら各層間には接着剤が使用されておらず、一体接合している。
Moreover, since the thermoplastic polyurethane material is used, the phosphorescent marker plate has a certain degree of flexibility, and can be attached to an attachment surface other than a flat surface.
Specifically, it can be used to flexibly adapt to evacuation guidance signs attached to subways and underground mall columns, and other surfaces with different curvatures.
Furthermore, since a magnetic material is present in the white reflective layer, it is possible to easily attach the phosphorescent marker plate to a necessary place without using a double-sided tape or an adhesive.
Further, the white
ついで、PET(ポリエチレンテレフタレート)フィルムからなる透明保護層1の蓄光層2側の面には、非難口等の表示を表した意匠が施してあり、蓄光層2側と接着一体化される。
Next, the surface of the transparent protective layer 1 made of a PET (polyethylene terephthalate) film is provided with a design representing a display such as a blunt mouth, and is bonded and integrated with the
上述の発明は、屋内用の案内標識板、地下鉄や地下駐車場の安全標識板や安全誘導表示板に用いられることはもとより、工場や大型店舗の誘導標識としても利用可能である。 The above-mentioned invention can be used as a guide sign for a factory or a large store as well as used for an indoor guide sign board, a safety sign board or a safety guidance display board in a subway or underground parking lot.
