The disaster prevention / fire prevention article of the present invention has a base and a resin layer disposed on the surface thereof, and the resin layer 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 the phosphorescent material particles and the reflector particles, the average particle diameter of the glass beads is larger than the average particle diameter of the phosphorescent material, and the average particle diameter of the phosphorescent material is larger than the average particle diameter of the reflector The glass beads are unevenly distributed near the surface layer, and the phosphorescent material is unevenly distributed near the inner layer, and the structure forms a light emitting part having both retroreflective and phosphorescent characteristics. It is characterized by being.

  In the present invention, the disaster prevention / fire prevention article is prepared for the purpose of disaster prevention / fire prevention, for example, various clothing such as an upper garment or a lower garment for a fire brigade / fire brigade, and the general public. Hats, hoods, hoods, helmets, gloves, shoes, rucksacks, bags, various storage bags, ropes / strings, various sheets, etc. that can be suitably used. The disaster prevention and fire prevention article of the present invention does not need to be arranged the above-mentioned resin layer (light emitting part) on the entire surface area, as long as it is provided in a position that is relatively easy to see on a part of the surface, Or more typically, it should just be provided especially in the part which can be moved, ie, the position etc. which can send a signal effectively with respect to the observer.

  FIG. 1 is an external perspective view schematically showing an embodiment of the disaster prevention / fire prevention equipment according to the present invention, and particularly shows fire prevention clothing for a fire brigade / fire brigade. FIG. 2 is a cross-sectional view of an essential part schematically showing an example of a structure of a resin layer portion constituting a disaster prevention / fire prevention article according to the present invention (stacked transfer example), and FIG. 3 according to the present invention. It is principal part sectional drawing which showed the other one example of the structure of the resin layer part of a disaster prevention and fire prevention article (printing example by an ink) typically.

  Referring to FIG. 1, a fire prevention garment 1 as a disaster prevention / fire prevention article according to the present invention is generally formed of a fire prevention garment made of a material excellent in heat resistance, fire resistance, fire resistance, etc. (aramid fiber, metal-deposited fiber, etc.). However, on the surface thereof, 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 at key points such as a skirt, a chest, an upper arm, and a back surface (not shown), A resin layer 2 containing phosphorescent material particles and reflector particles is formed as a light emitting layer. The light emitting part 2 made of the resin layer has a structure in which the above-mentioned glass beads are unevenly distributed closer to the surface layer and the phosphorescent material is unevenly distributed closer to the inner layer, and the light emitting part 2 made of the resin layer is retroreflected. It is comprised as a location which has a characteristic and a luminous characteristic in a superimposition together in the same location.

  The installation position and size of the light emitting unit need to be configured to have an appropriate thickness and color so that the light emitting unit can be visually recognized well, but may be determined in consideration of the overall balance and the like. Also, it may be equivalent to a conventional similar one.

  FIG. 2 and FIG. 3 both show an example of the structure of the resin layer 2, and FIG. 2 shows a typical example of the structure when each layer is laminated and transferred. FIG. 3 shows an example of a typical structure when formed by a printing method using an all-in-one type resin ink described later.

  In these drawings, a resin layer 5 is formed on the surface (base) 8 of the disaster prevention / fire prevention article 1 and is carried on the resin layer 5, so that glass beads 4, a phosphorescent material 6, and a reflective material 7 are present. is doing. Reference numeral 3 denotes an adhesive layer provided as necessary. When the resin layer 5 is formed by a thermal transfer sheet method, it is usually a hot melt resin layer. The entire resin layer 5 may be formed of a laminate of a plurality of layers as shown in FIG. 2, or may be formed of a single layer as shown in FIG.

  The disaster prevention / fire prevention article of the present invention has a structure as shown in FIG. 2 and FIG. 3 so that the resin layer 5 has both recursive reflection characteristics and luminous characteristics. When the viewer irradiates a light or the like, the reflected light returns directly toward the viewer, and the light emitting layer can be visually recognized instantly and accurately.

  Here, the recursive reflection is substantially the same as the incident direction, as shown in FIG. 4A as a model of the relationship between the array of glass beads 4 and the incident light E and the reflected light R. Reflection with the property of reflecting light in the direction, even if it is from the front or oblique position, if the viewer irradiates the disaster prevention / fire prevention equipment, the viewer can recognize it as bright direct reflected light .

  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), a retroreflective effect that is particularly excellent in visibility is obtained. In particular, the preferred range of the refractive index is 1 0.8-2.1, the preferred range of the glass bead diameter is 50-250 μm, and the most preferred range is 50-120 μm.

  FIG. 4B is a model diagram showing the direction of the incident light E and the reflected light R in the specular reflection. In such a reflection (specular reflection), the viewer can see the disaster prevention / reflection from an oblique position. When irradiating light to fire prevention equipment, the reflected light recognizes the information shown on the disaster prevention / fire prevention equipment (vertical color lines or / and identification characters / symbols) immediately and reliably to the viewer. In terms of making it, it can hardly contribute.

  4 (a) and 4 (b), B represents a base (substrate, support), but 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.

  In the present invention, many glass beads 4 are unevenly distributed particularly near the surface layer of the resin layer 5. Since the glass beads 4 are carried on the resin layer 5 and unevenly distributed near the surface layer, the retroreflection shown in a model in FIG. 4A is more effectively realized.

  It is important to use glass beads 4 that are colorless and transparent or light and transparent. By doing so, it is assumed that the color of the resin layer 5 or the color of incident light is pure. The reflected light will be visually recognized. The resin layer 5 may contain a pigment or a dye pigment as desired, and the resin layer is preferably composed of a pigment and a colorless and transparent resin component.

  And while having the above-mentioned retroreflective property, in the disaster prevention and fire prevention goods of this invention, the resin layer 5 also contains the particle | grains of the phosphorescent material 6, and the dark condition where the light is not irradiated In such a case, light is emitted due to the phosphorescent characteristics, so that the viewer can visually recognize.

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. Use what you have. 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. The phosphorescent material is preferably used in the form of particles from the viewpoint that the afterglow luminance and the afterglow time can be increased, and the average particle diameter is preferably 0.5 to 200 μm, It is preferably 5 to 100 μm, and most preferably 10 to 60 μm.

  The presence of this phosphorescent material, and the glass beads and resin layers are made of transparent materials (colorless or light colored), so they are particularly harmful because of their reduced emission luminance. Therefore, the phosphorescent characteristics can be exhibited well.

  In the present invention, the reflecting material 7 shown in FIGS. 2 and 3 is a light reflecting material (different from glass beads), and in order to positively have a function of reflecting light more strongly, In this case, the reflector particles (reflecting mirror) are contained.

  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 can cause multiple layer reflections of light in order to reflect some light and transmit some light. The transmitted light is also reflected by the lower reflecting material (such as mica), and in particular, when a pigment is present, it is reflected through the pigment, and the amount of light as retroreflected light, This contributes to the effect of improving color strength and clarity.

  Reflector particles (such as mica particles) 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 one having a diameter smaller than that of the glass beads because it can act as a layer that reflects light transmitted between the glass beads.

  Further, when the resin layer 5 is configured to contain a pigment, the particle size of the pigment (pigment, dye) should be as small as possible, preferably about 0.01 to 10 μm, more preferably 0. It is better to use a thing of about 1-1 micrometer. 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 dye is used as a reflector particle or a mica particle as a transmissive reflector particle. As a result, the ratio of the light that reaches the reflector and the transmissive reflector particles (mica particles) is increased, and the amount of reflected light is reduced.

  In the case of using a medium or a base resin (dispersion medium resin), the resin layer 5 is preferably made of a transparent material that does not affect light emission or color development and has heat resistance, 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.

  Although it does not specifically limit in order to manufacture the disaster prevention and fire prevention goods of this invention which has the resin layer 5 in which the glass bead 4 is unevenly distributed near the surface, typically, for example, the following ( It can be produced by any one of A), (B), and (C).

(A) 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 6 is provided by printing or coating with phosphorescent ink on a sheet of beads 4 in which glass beads are spread all over.
(2) Further, a reflective layer is provided by printing or coating from above with a resin ink containing the reflective material 7 and white pigment.
(3) Next, the hot melt adhesive resin layer 3 is printed or coated on the reflective material layer to complete the transfer sheet.
(4) When this transfer sheet is stacked on the base 8 of the disaster prevention / fire prevention article and hot pressed, the hot melt resin layer and the base are bonded.
(5) After sufficiently cooling, the base film (not shown) of the bead sheet is peeled off, and typically, the disaster prevention / fire prevention article according to the present invention having the laminated structure as shown in FIG. 2 is manufactured. be able to.
In the disaster prevention / fire prevention article formed by the transfer in this way, the glass beads 4 are on the entire surface of the layer 5, so that the retroreflection is favorably performed. And since the glass bead 4 is transparent, when the phosphorescent material 6 located inside it emits light, the light passes through the glass bead 4 and is visually recognized from the outside. On the other hand, the transparent resin containing the phosphorescent material 6 has no shielding property. For this reason, the reflective material 7 and a white pigment (a reflective material coated with a white pigment) are further placed inside, and a reflective material layer (7) having shielding properties is provided. By adopting such a configuration, for example, even if the disaster prevention / fire prevention article is colored, phosphorescence or reflected light can be obtained without being influenced by the color of the disaster prevention / fire prevention article.
Since the phosphorescent resin layer 6 has no shielding power and allows a part of the light to pass therethrough, the light that has passed through can reach the reflection layer 7 and repel the light. The hot melt resin adhesive layer 3 can be made to have elasticity that can sufficiently withstand the swelling / deformation of the disaster prevention and fire prevention equipment for some reason by mixing a rubber adhesive resin. It is.

  In the case of a printing method, a screen printing method or the like can be adopted, but it can be manufactured by the following method (B) or (C).

(B) When using a resin ink containing glass beads, a phosphorescent material and a reflecting material, and optionally a pigment (in the present invention, for convenience of explanation, such a resin ink is referred to as 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 glass beads 6 are reflected on the top, then phosphorescent material 7, and finally (bottom). Typically, as shown in FIG. 3, by adjusting and setting the mutual relationship of the average diameter of the particles (and the mutual relationship of specific gravity as necessary) so as to constitute a layered structure like the material 8 A printed material having such a multilayer structure and having both functions of reflection and phosphorescence can be manufactured.
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 important to use a layer of phosphorescent material and a layer of reflective material clearly, and it is important in that both phosphorescent performance and retroreflective performance can be favorably retained. The glass beads have an average particle diameter of 2 to 5 times the average particle diameter of the phosphorescent material, and the average particle diameter of the phosphorescent material is 2 to 5 times the average particle diameter of the reflector, which is surely laminated It is preferable in that a separated layer 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, it is preferable to use a pigment that is smaller than the reflecting material, but generally, since the pigment particles are very small, there are few problems in that respect.

(C) In the case of the resin ink for causing the reflection / phosphorescence function by the multistage printing method to appear:
In order to perform multi-stage printing directly on a base material for disaster prevention and fire prevention equipment, first, a shielding layer is printed on the base material. The shielding layer can be printed with a resin ink containing the reflective material 7 and a white pigment so that the color of the substrate is not visible from the surface when the substrate is colored. Next, printing is performed with a resin ink containing the phosphorescent material 6. 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 transparent resin ink containing glass beads 4. The disaster prevention / fire prevention article formed by multi-stage printing in this way has both functions of reflection and phosphorescence.

  As described above, there are various methods for producing the disaster prevention / fire prevention article of the present invention. Particularly, when the transfer method and the multi-stage printing method are used, the glass beads 4 are formed in an orderly manner. Therefore, it is possible to manufacture the resin layer 5 that can exhibit the retroreflective effect with high stability. In the case of manufacturing by a printing method using all-in-one ink, since the glass beads 4 become a resin layer 5 presenting some unevenness, the retroreflective characteristics are somewhat inferior. According to these various findings, it is high enough that there is no problem in practical use.

  In the present invention, the resin layer forming the light emitting portion may be in the form of a sheet or tape. Or a dot-like thing etc. may be sufficient and the shape and form which have a specific meaning may be comprised.

Further, when the level of the phosphorescent function was also confirmed, 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. It was expensive.
