  The fire fighting / disaster prevention / safety sign plate and the fire fighting / disaster prevention / safety sign plate making kit of the present invention will be described in more detail below.

The sign plate for fire fighting / disaster prevention / safety of the first aspect of the present invention uses the following sheets (A) and (B), one of which is used as a ground sheet for forming the ground, and the other is an identification type. Is used as a mold sheet to form a plate having an information display / marking function.
(A) It has a large number of glass beads having a refractive index of 1.5 to 2.2 and a particle size of 10 to 250 μm and a color ink layer, and the color ink layer and the glass beads are close to the surface layer of the color ink layer. A retroreflective sheet formed in such a manner that many glass beads are unevenly distributed and the glass beads are supported on the color ink layer,
(B) a phosphorescent sheet containing a phosphorescent material,
Each of the sheets (A) and (B) is combined and formed into one plate, and one of the sheets is used as a ground sheet, and the other is used as a mold sheet forming an identification mold.

  The identification type refers to a type for forming a mark, a pattern, a character string, or the like that exhibits an identification function for information transmission as various firefighting / disaster prevention / safety sign plates. For example, a pattern sheet consists of a character string such as "fire extinguisher" or "emergency exit", a design in which a person runs to the design of an emergency exit, or a design in which a person walks to the stairs. A sheet whose outer contour that can be made is shaped into a specific mold. The mold formed by the mold sheet may form a positive shape, but may form a negative shape.

  In short, which is a mold sheet and which is a ground sheet is only a matter of view, so it is not a very important concept in the present invention, and at least two kinds of sheets are combined to identify each other as a whole. For example, a mark, a pattern, a character string, or the like may be formed.

  FIG. 1 illustrates the configuration of a fire fighting / disaster prevention / safety sign plate according to the present invention. FIGS. 1 (a) to 1 (c) are one fire fighting / disaster prevention / safety sign plate. The way of visual recognition (how it looks) is a schematic model diagram explaining that there are three types of modes.

  In FIG. 1, the fire fighting / disaster prevention / safety sign plate 1 according to the present invention is composed of a mold sheet (or ground sheet) 1A and a ground sheet (or mold sheet) 1B when viewed from the front. By combination, certain information to be informed to the viewer is added on the label plate. FIG. 4A is a model representation of how the installation site looks in a normal state. For example, a 1A portion is formed in dark green, and a 1B portion is formed in bright light yellow green. It is visually recognized. FIG. 4B is a model representation of the appearance in retroreflected light. For example, the 1A portion looks bright light blue while the entire reflected light shines. It looks like gold to silver, and the visibility of information as a whole plate is very good. Also, (c) in the figure shows that even though the space around the viewer and the sign plate is very dark, the arrow and exit pattern in the sign plate appear to emerge due to phosphorescence in a dark ground color. Visibility is demonstrated.

  Here, the recursive reflection (light) described in FIG. 1B is a model of the relationship between the array of glass beads 2, the incident light E, and the reflected light R in FIG. 7A. As described above, this refers to reflection (light) that reflects light in almost the same direction as the incident direction. As long as the viewer irradiates the sign plate with light even from the front or oblique position. The viewer can recognize the reflected light as bright direct reflected light, can immediately and reliably recognize the information shown on the sign plate, and can know how to deal with it.

  This recursive reflection is an optical characteristic of a reflective material such as glass beads. In particular, in the present invention, a specific refractive index range (refractive index is 1.5 to 2.2) and a specific refractive index. By using glass beads having a particle size range (particle size of 10 to 250 μm), it is possible to obtain a retroreflective effect that is particularly excellent in visibility. In particular, the preferable range of the refractive index is 1.8 to 2.1, the preferable range of the diameter of the glass beads is 50 to 250 μm, and the most preferable range is 50 to 120 μm.

  FIG. 7B is a model diagram showing the direction of the incident light E and the reflected light R in the specular reflection. In such a way of reflection, the viewer can apply light to the marker plate from an oblique position. The reflected light hardly contributes in that the information shown on the sign plate is immediately and reliably recognized by the viewer.

  7A and 7B, B indicates a base (base, support). However, when the base B contains a dye, the color of the dye is reflected light R. The color can be visually recognized, and the visibility can be improved by the color. A pigment, a dye, or both are used as the coloring matter, and the chromatic color (red, blue, yellow, etc.) is added to the retroreflected light so that the visibility is further improved.

The fire fighting / disaster prevention / safety sign plate according to claim 1 of the present invention (first present invention) includes a region having the function of retroreflecting described above, and a region having a phosphorescent function by containing a phosphorescent material. In combination with, a mark, a pattern, a character string, etc. are formed, and useful information is displayed in the event of an emergency. Here, the phosphorescent function is a function that absorbs light energy such as sunlight and fluorescent lamps and emits light by converting the stored energy into visible light, and has been known as a phosphorescent paint. What is necessary is just to apply | coat to a base | substrate by application | coating, printing, etc. suitably. That is, a sulfide-based material (for example, a chemical composition of ZnS: Cu) or an oxide-based material (for example, a chemical composition of SrAl ₂ O ₄ : Eu, Dy) can be used. From the viewpoint of increasing the amount of emitted light (afterglow luminance) and the afterglow time, as well as heat resistance and durability, it is preferable to use an oxide type. In addition, the phosphorescent material is preferably used in the form of particles in terms of increasing afterglow luminance and afterglow time and ease of application, and the average particle size is preferably 0.5 to 200 μm. It is preferable to use one having a thickness of 5 to 100 μm, most preferably 10 to 60 μm.

  Examples of the specific structure of the fire fighting / disaster prevention / safety sign plate according to the first aspect of the present invention will be described with reference to FIGS.

  FIGS. 2 to 4 show model examples of the fire fighting / disaster prevention / safety sign plate 1 according to the first invention, and the fire fighting / disaster prevention / safety sign plate 1 of the present invention. Comprises a retroreflective sheet composed of at least a large number of glass beads 2 having the above-mentioned specific refractive index and diameter and the color ink layer 4, and there are many glass beads 2 especially near the surface layer of the color ink layer 4. It is supposed to be unevenly distributed. Since the glass beads 2 are carried on the color ink layer 4 and unevenly distributed near the surface layer, the retroreflection shown in a model in FIG. 7A is more effectively realized.

  It is important to use a colorless and transparent glass bead 2. By doing so, reflected light is visually recognized as a pure color of the color ink layer 4. The color ink layer is made of, for example, a pigment or dye pigment and a colorless and transparent medium component or resin component.

  In FIG. 2, reference numeral 5 denotes a shielding layer, which is formed of an opaque white resin layer configured to contain a white pigment, for example. Due to the presence of the shielding layer, the amount of light is large and the reflected light becomes strong, and the color of the reflected light becomes clear. In the shielding layer 5, particles having a function as a reflector particle (reflecting mirror) 6 may be included in order to positively have a function of reflecting light.

  For example, the reflective material includes aluminum particles, natural or artificial mica particles, and these particles can be typically used. The mica particles are generally translucent and transmit light half way, so that it is necessary to coat titanium oxide or the like so as to present a white reflecting surface in order to make the color of reflected light clear. preferable. Mica particles are generally thin plate-like particles, and in the present invention, either natural products or artificially synthesized products can be used. Mica particles form a layered structure, and are semi-transmissive and reflect some light and allow some light to pass through. Reflected by the mica particles on the side through the pigment, it contributes to the effect of improving the amount of light as retroreflected light, the strength of the color, and the sharpness. Reflector particles (such as mica particles) preferably have an average particle diameter (average major axis) of about 0.1 to 100 μm, more preferably 1 to 50 μm, and even more preferably about 5 to 25 μm. It is preferable to use a material having a particle size smaller than that of the glass beads because it can act as a layer that reflects light transmitted between the glass beads.

  Moreover, the particle diameter of the pigment | dye (pigment, dye) to be used should be as small as possible, Preferably it is about 0.01-10 micrometers, More preferably, about 0.1-1 micrometer should be used. . When the particle diameter of the dye is smaller than 0.01 μm, the price is generally high, which is not desirable. When the particle diameter is larger than 10 μm, the mica is used as a reflector, a reflector particle, or a transmissive reflector particle. The ratio that is larger than particles and the like is increased, and as a result, the ratio of blocking light reaching the reflector and the mica particles is increased, and the amount of reflected light is decreased, which is not preferable.

  In the case of using a medium or base resin (dispersion medium resin) in constituting the color ink layer or each layer, it is transparent and does not affect light emission or color development and has heat resistance. It is preferable to use so-called transparent ink resin. The resin can be organic or inorganic, and can be water-based or oil-based. Acrylic resin, urethane resin, nylon resin, polyester resin, etc. are easy to handle. Is preferably used.

  When the shielding layer 5 shown in FIG. 1 is not particularly provided in the plate of the first invention, reflector particles 6 such as aluminum particles and mica particles are provided in the color ink layer 4 as shown in FIG. What is necessary is just to contain.

  2 and 3, reference numeral 3 denotes a layer of phosphorescent material. In the embodiment shown in FIGS. 2 and 3, the entire label plate is formed of a sheet having the phosphorescent material layer 3, and the recursion described above is formed thereon. It has a configuration in which a mold reflective sheet is attached. That is, a portion that is not covered with the retroreflective sheet becomes a phosphorescent region, and an identification mark, a handle, or the like is configured with the region portion that is covered with the retroreflective sheet. The phosphorescent material layer 3 in the region not covered with the retroreflective sheet may have its surface covered with an appropriate synthetic resin film layer 7 such as polyester resin or vinyl chloride (aspect of FIG. 2), Alternatively, it may be directly exposed on the surface (the embodiment of FIG. 3).

  2 and 3, there is no particular limitation under the phosphorescent material layer 3, but for example, a layer such as a synthetic resin film layer 7, an adhesive layer 8, a release paper 9 is formed to form a plate The entire body (not shown) can be bonded and bonded.

  Further, the phosphorescent material layer 3 may contain a reflective material (aluminum particles, mica particles as transmissive reflective material particles, etc.). By doing so, it is possible to increase the amount of light (afterglow luminance) that is visually recognized using the reflecting function of them, which is preferable.

  FIG. 4 shows an example in which a retroreflective sheet and a phosphorescent sheet are formed and then formed on a plate using both of them as abutting each other. In this way, it is possible to form a plate structure in which the height difference between both regions is smaller.

  The fire / disaster / safety sign plate according to the second aspect of the present invention will be described below.

FIG. 5 and FIG. 6 each show an example of a specific structure of the fire-fighting / disaster-prevention / safety sign plate 1 according to the second aspect of the present invention. (C) and (D) are used, one of which is used as a ground sheet for forming a ground, and the other is used as a mold sheet for forming an identification mold, to a plate having an information display / marking function. It is a composition.
(C) A resin layer having a retroreflective property and a luminous property, which contains a large number of glass beads having a refractive index of 1.5 to 2.2 and a particle size of 10 to 250 μm, a reflector particle and a phosphorescent material, and the glass A lot of beads are unevenly distributed near the surface layer, and the phosphorescent material is a sheet made of a resin layer unevenly distributed near the inner layer,
(D) a resin layer having a retroreflective property and a luminous property, which contains a large number of glass beads having a refractive index of 1.5 to 2.2 and a particle size of 10 to 250 μm, a reflector particle, a phosphorescent material, and a pigment; The glass beads are unevenly distributed near the surface layer, and the phosphorescent material is a sheet made of a resin layer unevenly distributed near the inner layer,
That is, each sheet used as a ground sheet and a mold sheet has a retroreflective layer and a phosphorescent layer each containing a large number of glass beads 11 having a refractive index of 1.5 to 2.2 and a particle size of 10 to 250 μm. It is a retroreflective phosphorescent sheet that is configured to have at least, and the difference between the two is the difference in the color that is visually recognized. Therefore, it is important that at least one of the sheets contains a dye, and when both of them contain a dye, the dye should be used in such a way that the visible colors are different. That is, it is important to form the base sheet and the mold sheet by making the colors of the pigments different. The colorant is not particularly limited as long as it has a different color, and can be used in combination with pigments and / or dyes as described above.

  5 and 6, reference numeral 12 denotes particles of the phosphorescent material, 13A and 13B denote color ink layers, and the two colors are different from each other. The color ink layers 13A and 13B are preferably composed of colored and transparent ones, and one of them may be formed of a colorless and transparent one that does not contain a pigment. 14 is a particle of a reflecting material, 15 is an adhesive layer, 16 is a release paper, and 17 is a plate substrate.

  It is important that the glass beads 11 be colorless and transparent so that the color of the pigment can be seen as it is. In order to enhance the retroreflective properties, at least the sheet (C) and (D) In one or both of the sheets, it is preferable to use semi-transmissive reflector particles such as mica particles coated with titanium oxide or the like in white as the reflector particles 14. The effect of mica particles as reflector particles is that, as mentioned above, mica is generally like a translucent mirror, and has little hindrance to the transmission of incident or reflected light. In addition, the amount of retroreflected light can be increased and the color due to the pigment can be made clear and strong, and the amount of light emitted due to phosphorescent coloring (afterglow luminance) does not cause a drop in visual recognition. Is preferred.

  The preferable range of the particle size of the glass beads, the particle size of the phosphorescent material, the particle size of the reflector (such as mica particles) and the particle size of the color difference are the same as described in the first aspect of the present invention. Further, the medium and the base resin (dispersion medium resin) are the same as those described in the first aspect of the present invention.

  By adopting such a configuration, each of the ground sheet and the mold sheet has a function as a retroreflective material sheet and a function as a phosphorescent material sheet, but the visually recognized colors are different between the two. Therefore, even in the event of an emergency, the information display / marking function can be satisfactorily exhibited by reflected light or phosphorescent light emission even in a situation where light can be irradiated using a light or the like, or in a situation where there is no light. .

  As shown in FIGS. 2 to 6, in the layer structure of each sheet, it is important to increase the retroreflective performance that the glass beads are unevenly distributed closer to the surface layer.

  The sheet having the structure may be formed by a multi-stage lamination method using a multi-stage printing method, a method of transferring after forming a multi-layer printing sheet by multi-stage printing, or a glass bead, a phosphorescent material, a reflective material, or a coloring matter depending on circumstances. It can be formed by a method of screen printing at a time using a resin ink in which all are mixed (this is called an all-in-one type resin ink in the present invention for convenience). In the case of the method of printing at a time, the size relationship of particle diameters such as glass beads, pigment particles, phosphorescent material particles, and transparent reflector (mica) particles (the diameter of the glass beads is made larger than that of the other, By setting the size of the transparent reflector (mica) particles smaller than the others, etc., many glass beads are unevenly distributed near the surface in the process of solidifying the ink layer after printing. In addition, pigment particles, phosphorescent material particles, reflector particles, or transmissive reflector particles (mica particles) can be distributed in a large amount downward.

  More specifically, many glass beads are unevenly distributed near the surface, and below that, pigment particles, phosphorescent material particles, and further, reflector particles or transmissive reflector particles (such as mica particles) are more distributed. Three cases will be described with respect to the manufacturing method.

  That is, the formation of the resin layer in which the glass beads 2 and 11 are unevenly distributed near the surface is not particularly limited, but typically, for example, the following (I) and (II) , (III). In addition, when not using a pigment | dye, it is good to form a layer structure, without making it contain suitably.

  In the case of forming the labeling plate of the second aspect of the present invention, at least one of the following (I), (II), and (III) is used for at least one of the sheet (C) and the sheet (D). It is preferable to manufacture by these methods.

(I) Transfer sheet method:
In the case of the transfer sheet method, it can be produced by processing in the following order (1) to (5).
(1) A phosphorescent resin layer containing a phosphorescent material 12 is provided on a sheet of beads with glass beads 11 spread all over by printing or coating with phosphorescent ink.
(2) Further, a reflective layer is provided by printing or coating from above with a resin ink containing a reflective material and a white pigment.
(3) Next, a hot melt adhesive resin layer is printed or coated on the reflective material layer to complete a transfer sheet.
(4) When this transfer sheet is stacked on a substrate and hot pressed, the hot melt resin layer and the substrate are bonded.
(5) A resin layer having a structure as shown in FIG. 5 can be produced by peeling off the base film (not shown) of the bead sheet after sufficiently cooling.
In the resin layer formed by transferring in this way, since the glass beads are on the entire surface of the layer, retroreflection is favorably performed. Since the glass beads are transparent, when the phosphorescent material in the resin layer containing the phosphorescent agent located on the inside emits light, the light passes through the glass beads and is visually recognized from the outside. For the resin layer containing the phosphorescent material, a colored or colorless transparent resin containing a pigment is used. Furthermore, if the reflective material 14 and the white pigment (the reflective material coated with the white pigment) are provided inside and a reflective material layer having a shielding property is provided, better light accumulation and reflected light can be obtained. Since the layer (12) of the phosphorescent resin layer has no shielding power and allows part of the light to pass therethrough, the light that has passed through can reach the layer (14) of the reflective layer material and bounce off the light. Furthermore, the hot melt resin adhesive layer 15 can be made to have elasticity that can cope with deformation and the like by mixing a rubber adhesive resin into the hot melt resin adhesive layer 15.

  In the case of the printing method, a screen printing method or the like can be adopted, but it can be produced by the following method (II) or (III).

(II) When using glass beads, a phosphorescent material and a reflective material, and a resin ink containing a pigment in some cases (that is, an all-in-one type resin ink):
In order to print with fluid all-in-one type resin ink and efficiently express both the reflection function and the phosphorescence function, the particle size of each material constituting the resin ink is controlled as follows. create.
That is, for example, when mixing large particles and small particles in a beaker, they are mixed evenly, but when the beaker is vibrated and tapped, the particles with larger particles gradually become smaller and smaller. Can be caused by printing resin ink, but the glass beads are the top, the phosphorescent material, and the last (bottom) reflector. Thus, the particle diameter is adjusted so as to constitute a layered structure, whereby a resin layer having a structure as shown in FIG. 6 having both functions of reflection and phosphorescence can be produced.
In forming such a layered structure, the average particle diameter of each particle used should be 10 to 250 μm for glass beads, preferably 50 to 250 μm, most preferably 50 to 250 μm. It is to use the thing of the range of 120 micrometers. It is preferable to use a phosphorescent material having an average particle diameter of 0.5 to 200 μm, more preferably 5 to 10 μm, and most preferably 10 to 60 μm. It is preferable to use a reflector having an average particle diameter of 0.1 to 100 μm, more preferably 1 to 50 μm, and most preferably 5 to 25 μm.
Within such a range, the mutual relationship between the particle sizes is such that the average particle diameter of the glass beads is larger than that of the phosphorescent material, and the average particle diameter of the phosphorescent material is larger than that of the reflector. It is preferable to use a phosphorescent material layer and a reflective material layer in terms of clearly forming the phosphorescent material and the retroreflective performance. The average particle diameter is 2 to 5 times the average particle diameter of the phosphorescent material, and that the average particle diameter of the phosphorescent material is 2 to 5 times the average particle diameter of the reflective material It is preferable in that it can be formed. If each difference is less than 2 times, it is difficult to form a clear layered structure. If it exceeds 5 times, the surface becomes rough or the texture becomes hard and heavy. Is not preferable because it tends to drop off. In addition, although it is preferable to use a pigment that is smaller than the reflecting material, generally, the pigment particles are very small, and there are few problems in that respect.
Further, the sheet (A) having the structure as shown in FIG. 3 has a structure in which many glass beads 2 are unevenly distributed near the surface layer and many reflector particles 6 are unevenly distributed near the inner layer. However, the resin layer structure having such a structure also sets the average particle diameter of the glass beads, 2 and the reflector well, specifically, the average particle diameter of the glass beads is 2 that is the average particle diameter of the reflector. It can be obtained by mixing them with a dispersion medium resin and, if necessary, a dye or the like to form a mixed resin ink, and performing printing in one step using the ink.

(III) In the case of resin ink for causing the reflection / phosphorescence function by the multistage printing method to appear:
In order to perform multi-stage printing directly on the base material of the label plate, first, a shielding layer is printed on the base material. When the base material is colored, the shielding layer prevents the color from being seen from the surface. Therefore, the shielding layer may be printed with a resin ink containing the reflective material 14 and a white pigment. Next, printing is performed with a resin ink containing the phosphorescent material 12. In this resin ink, a reflective material (a reflective material having a particle diameter smaller than that of the phosphorescent material in order to be positioned further downward in the layer) may be added. Thereafter, printing is performed with a colored or colorless transparent resin ink containing glass beads 2 and 11. The resin layer formed by multi-stage printing in this way has both the functions of reflection and phosphorescence.

  As described above, there are various methods for manufacturing the fire fighting / disaster prevention / safety sign plate of the present invention. In particular, when the transfer method and the multi-stage printing method are used, the glass beads 2 and 11 are arranged in an orderly manner. It is easy to form a supported state, and it is possible to manufacture a laminated structure of resin that can exhibit a retroreflective effect highly and stably. In the case of manufacturing by a printing method using an all-in-one type resin ink, since the glass beads 2 and 11 are resin layers existing side by side with some irregularities, the retroreflective properties are somewhat inferior, According to the various knowledge of the present inventors, it is sufficiently high so that there is no problem in practical use.

  The fire-fighting / disaster-prevention / safety sign plate according to the present invention has, for example, a general structure as shown in FIG. 1 or has only characters such as “fire extinguisher” and “emergency exit”. If so, the final form can be completed at the factory and shipped on the distribution channel. On the other hand, depending on the sign's installer, the evacuation shown in more detail according to his / her installation location. There may be a desire to install a route map on a sign plate.

  In such a case, the fire fighting / disaster prevention / safety sign plate of the present invention described above is a fire fighting element in which a plurality of sheet-like objects for the ground sheet and the mold sheet are components as one kit. -It is also useful to manufacture as a kit for preparing a disaster prevention / safety sign plate and to ship it on the distribution channel in that mode. The preparation kit may include, for example, an arrow, a template or a template such as a human figure or an “emergency exit”. Alternatively, the kit may be configured by combining mold sheets or ground sheets formed in necessary mold parts such as arrow molds and character strings from the beginning.

  In addition, it is preferable that the sign plate for fire fighting / disaster prevention / safety of the present invention is a sheet-like flat plate because it is widely visible from the surroundings (180-degree field of view). It is also preferable to use it by sticking to objects that are curved or pillars of objects, structure pillars and frames, in which case a 360-degree field of view can also be expected. The base is preferably formed of a flexible material such as rubber-based resin or rubber-based adhesive resin.

  For example, a reflective material such as a bicycle that is installed all around the frame pipe or a reflective material that is affixed to the helmet surface, etc., does not reflect light when it is not directly illuminated in the dark at night. Although it is difficult to be visually recognized, when the marker sheet of the present invention is used, it is easily visible even in the dark due to the light emission function by phosphorescence.

Example 1
A phosphorescent material having an average particle diameter of 25 μm is used as a phosphorescent material, and a urethane-based resin is used as a dispersion medium resin. A phosphorescent material layer having the same configuration as shown in FIG. 3 is printed on the entire surface of the plastic plate by a printing method. Thus, a rectangular phosphorescent plate was formed.
On top of that, using the all-in-one type resin ink (glass phosphor is not included in this case) containing glass beads, reflective material and dark green pigment in one ink, the label shown in FIG. A 1A mold (around arrow or human figure) was printed. The dispersion medium resin is a urethane resin from the viewpoint of durability. The glass beads have a refractive index of 1.93 and an average particle size of 63 μm, and the reflective material has an average particle size of 12 μm and is white with titanium oxide. Using artificial mica coated on the surface.
As a result of confirming the level of the retroreflective function by illuminating this sign plate at night, the reflected light from a distance of 70 m can be clearly seen with the naked eye. Especially, even when the light is obliquely reflected, It was possible to see well from the direction near 180 degrees. Moreover, when it was dark, the arrow by phosphorescence emission was visible visually.

Example 2
As shown below, the label plate shown in FIG. 1 was manufactured by a screen printing method using two types of all-in-one type resin ink containing glass beads, a phosphorescent material, a reflective material, and a pigment in one ink.
The cross-sectional structure is shown schematically in FIG. 6, the urethane resin is used as the dispersion medium resin, the refractive index of the glass beads is 1.93, the average particle diameter is 53 μm, and the average particle diameter of the phosphorescent material is 26 μm. The average particle size of the reflective material is 12 μm, and artificial mica coated with titanium oxide in white is used. One kind of resin ink contains a small amount of light yellow-green pigment, and the other kind is dark green. It contains a pigment.
The former resin ink containing the light green pigment printed the type 1B of FIG. 1, and the latter resin ink containing the dark green pigment printed the type 1A of FIG.
As a result of checking the level of the retroreflective function by applying light to the plate at night, the reflected light from a distance of 70 m was clearly visible with the naked eye.
The level of the phosphorescent function was also confirmed. As a result, the afterglow luminance was about 320 mcd / m ² , the afterglow time was 1000 minutes or more, and the light resistance was 1000 hours or more.
