Description

  The present invention relates to a fire hose. More specifically, the present invention relates to a fire hose capable of exhibiting a reliable guiding function with high visibility for a long time when a fire brigade member returns from a fire site such as a dark place.

  In fire extinguishing activities such as building fires, firefighters hold a water discharge nozzle and infiltrate the fire site deep inside the building while dragging and extending the fire hose connected to the water discharge nozzle to extinguish the fire. Then, when it is determined that the fire should be evacuated, the situation should be evacuated, or when the water is used up, the fire hose that has been deployed so far is used as a road guide to return to the outside of the fire building such as a building. Like to do.

However, since the building that caused the fire is generally in a power outage, the firefighters must return only relying on the fire hose line extending the building with a complex structure in dark darkness and smoke. There are things that must be done.
Therefore, it is desired to realize a fire hose that can instantly and surely recognize the presence of the fire hose extending to the destination even under such circumstances, and various proposals have been made to cope with it.

  For example, the thing which applied the reflecting material to the whole hose (patent document 1), and the thing which provided the light emitting layer which uses a reflective layer or a fluorescent substance as a pigment along the hose longitudinal direction (patent document 2) are proposed. However, these still have room for improvement in visibility under dark and poor lighting conditions.

  In addition, light-emitting paint such as phosphorescent paint or fluorescent paint is continuously or intermittently attached to at least one of both side edges of the hose body flattened over the entire length of the hose body, or a female bracket along the hose longitudinal direction. A fire hose is proposed in which marks made of luminescent paint such as phosphorescent paint or fluorescent paint with a shape pointing to the side are attached in rows (Patent Documents 3 and 4). It is also proposed to add a reflective material (paragraph 0021 of Patent Document 3 and paragraph 0016 of Patent Document 4).

  However, in these proposals, it is necessary to uniformly disperse the reflective material in the phosphorescent paint, and in many cases, the desired effect cannot be obtained.

  FIG. 1 is an external perspective view schematically showing an embodiment of a fire hose according to the present invention.

FIG. 2 shows a resin layer portion constituting vertical color lines and / or identification characters / symbols of a fire hose other than the present invention, and a plurality of layers are laminated to form a whole. It is principal part sectional drawing which showed the example (lamination transfer example) modelly. FIG. 3 shows a resin layer portion constituting vertical color lines and / or identification characters / symbols of a fire hose according to the present invention, and a resin by printing using the all-in-one type resin ink according to the present invention. It is principal part sectional drawing which showed the example of the one aspect | mode of the single layer structure of the layer as a model.

  In FIG. 1, a fire hose 1 according to the present invention is provided with a vertical color line 2 drawn straight in the length direction of a hose on the surface of a jacket, and shows some information or the like in an easily viewable place. An identification character / symbol 3 is provided. 4 is a color line which shows the ear | edge end part when folded and accommodated. Although not shown, a male fitting and a female fitting are attached to both ends of the fire hose 1.

In the fire hose of the present invention, the structure of the hose body may be the same as that of the conventional one, but in particular, the vertical color line 2 and the identification character / symbol 3 described above have a refractive index of 1.5 to 1 or both. 2.2 having a large number of glass beads having an average particle diameter of 50 to 120 μm, a phosphorescent material having an average particle diameter of 10 to 60 μm , and a reflecting material having an average particle diameter of 5 to 25 μm and having retroreflective properties and phosphorescent properties It consists of a resin layer of a single layer structure, the average particle diameter of the glass beads is 2 to 5 times larger than the average particle diameter of the phosphorescent material, and the average particle diameter of the phosphorescent material is the average particle of the reflector 2 to 5 times greater than the diameter, and the glass beads were unevenly distributed more to the surface closer while accumulating light material is unevenly distributed most in the inner layer nearer, and said reflective material is further inner layer nearer the phosphorescent material resin forming the structure are unevenly distributed many In that it is formed, it further the resin layer, the glass beads, in which is formed by printing once with including at least a single resin ink tripartite phosphorescent material and a reflective material There is a feature.

FIG. 3 shows an example of the structure, and the resin layer 5 is formed as a single layer on the surface of the cabinet 10 of the fire hose 1 and is carried on the resin layer 5. There are glass beads 6, phosphorescent material 7, and reflective material 8. It is a feature of the present invention that the resin layer 5 is formed as a single layer as shown in FIG. As shown in FIG. 2, a plurality of layers are laminated so as to form a single layer as a whole is not included in the present invention. In FIG. 2, reference numeral 9 denotes an adhesive layer provided as necessary to form a laminate. When the resin layer 5 is formed by a thermal transfer sheet method, it is usually a hot melt resin layer.

The fire hose of the present invention has a structure as shown in FIG. 3 so that the resin layer 5 has a single layer structure having both recursive reflection characteristics and luminous characteristics, and is dark. When the viewer irradiates light etc., the reflected light returns directly to the viewer, and the vertical color line or / and the identification character / symbol can be visually recognized instantly and accurately. It is.

  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 6 and the incident light E and the reflected light R. Reflection of the nature of light reflecting in the direction, even from the front or oblique position, as long as the viewer irradiates light to the fire hose, can be recognized by the viewer as bright direct reflected light, The information shown on the fire hose (in the direction of the vertical color line of the hose (that is, the direction of the escape / return route leading to the outlet in the direction of the hose line) or / and the information of identification characters / symbols) You can recognize it reliably and know how to treat it when necessary.

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 50 to 120 μm ), a retroreflective effect that is particularly excellent in visibility is obtained. In particular, the preferred range of the refractive index is 1. .8 to 2.1.

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 observer can use the fire fighting from an oblique position. If will be irradiated with light hose, the information shown on the fire hose (Tateirosen or / and identification characters and symbols), viewer real and contributes little to it in terms of reliably recognized in It is not possible.

  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 6 are unevenly distributed particularly near the surface layer of the resin layer 5. Since the glass beads 6 are supported on the resin layer 5 and are unevenly distributed closer to the surface layer, the retroreflection shown in a model in FIG. 4A is more effectively realized.

It is important to use a glass bead 6 that is 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 fire hose of the present invention, the resin layer 5 also contains particles of the phosphorescent material 7, and the dark situation where the light is not irradiated, etc. In this case, light is emitted by the phosphorescent characteristics, and the viewer can visually recognize the light.

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 type (for example, chemical composition of ZnS: Cu) or an oxide type (for example, 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 it is important to use those having an average particle size of 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, 8 shown in FIGS. 2 and 3 is a light reflecting material (different from glass beads), and in order to have a function of reflecting light more strongly, such reflection is performed. It contains material particles (reflecting mirror). 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.

Reflecting material particles (mica particles), the average particle diameter (average major axis) is important to use of about 5 to 25 [mu] m, by Rukoto used as a smaller diameter than the particle diameter of the glass beads, glass Runode can act as a layer that reflects light transmitted through the between bead preferred.

  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 mica particle as a reflector particle or a transmissive reflector particle is used. As a result, the rate that is larger than the above becomes high, and as a result, the rate of blocking the light reaching the reflector and the transmissive reflector particles (mica particles) becomes high, and the amount of reflected light is reduced, which is not preferable. .

  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 fire hose which has the resin layer 5 in which the glass beads 6 are unevenly distributed near the surface, typically, for example, the following (A), ( It can be produced by any one of the methods B) and (C). Among them, the resin layer 5 can be produced as a single layer by the method (B) as in the present invention. The methods (A) and (C) are suitable for producing a resin layer in which a plurality of layers are laminated, and are not suitable for forming a resin layer according to the present invention.

(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 7 is provided by printing or coating with phosphorescent ink on a sheet of beads 6 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 8 and white pigment.
(3) Next, a hot melt adhesive resin layer 9 is printed or coated on the reflective material layer to complete a transfer sheet.
(4) When this transfer sheet is placed on the fire hose jacket (base material) 10 and hot pressed, the hot melt resin layer and the fire hose jacket are bonded.
(5) After sufficiently cooling, the base film of the bead sheet is peeled off, and typically a fire hose outside the present invention having a laminated structure as shown in FIG. 2 can be manufactured.
In the fire hose formed by transferring in this way, since the glass beads 6 are on the entire surface of the resin layer 5, they are retroreflected well. And since the glass bead 6 is transparent, when the phosphorescent material 7 located inside thereof emits light, the light passes through the glass bead 6 and is visually recognized from the outside. On the other hand, the transparent resin containing the phosphorescent material 7 has no shielding property. For this reason, the reflecting material 8 and a white pigment (a reflecting material coated with a white pigment) are further placed inside, and a reflecting material layer (8) having a shielding property is provided. By adopting such a configuration, for example, even if the fire hose is colored, phosphorescence or reflected light can be obtained without being influenced by the color of the fire hose.
Since the phosphorescent resin layer 7 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 8 and repel the light. The hot melt resin adhesive layer 9 can be made to have elasticity that can sufficiently withstand the swelling of the hose during water discharge by mixing a rubber adhesive resin.

  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 the glass beads 6 are at the top, then the phosphorescent material 7, and the reflector 8 below it. Typically shown in FIG. 3 by adjusting and setting the mutual relationship between the average diameters of the particles (and the specific gravity if necessary) so as to form a layered structure with the dye (dye / pigment). Thus, it is possible to produce a printed matter having a clear multilayer structure and a function of both reflection and phosphorescence although it is a single layer structure.
In forming such a layered structure, it is important to use glass beads having an average particle diameter of 50 to 120 μm. It is important to use a phosphorescent material having an average particle diameter of 10 to 60 μm. It is important to use a reflector having an average particle diameter of 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 material that can clearly form a layer of phosphorescent material and a layer of reflecting material, and can have both phosphorescent performance and retroreflective performance. The average particle diameter of the beads was 2 to 5 times the average particle diameter of the phosphorescent material, and the average particle diameter of the phosphorescent material was 2 to 5 times the average particle diameter of the reflector, clearly separated into a laminate It is important and essential in forming the layer.
If the difference is less than 2 times, it is difficult to form a clear laminated structure. If the difference is more than 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 since the pigment particles are generally 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 the base material of the fire hose, first, a shielding layer is printed on the base material (hose jacket). When the hose is colored, the shielding layer is to prevent the color from being visible from the surface. Therefore, the shielding layer may be printed with a resin ink containing the reflective material 8 and a white pigment. Next, printing is performed with a resin ink containing the phosphorescent material 7. 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 6. The fire hose formed by multi-stage printing in this way has both functions of reflection and phosphorescence.

As described above, there are various methods for manufacturing a fire hose. In particular, in the case of the multi-stage printing / transfer system and the multi-stage printing system (the above-mentioned methods (A) and (C)), the glass beads 6 Are easily formed in a single line, and a resin layer 5 capable of exhibiting a retroreflective effect with high stability can be manufactured , and the resin layer is composed of a plurality of layers. Become.
On the other hand, in the case of manufacturing by the printing method using the all-in-one type resin ink of the above-mentioned method (B), the glass beads 6 become a resin layer 5 presenting a few irregularities side by side. Although somewhat inferior direction, so as no practical problem, according to various findings of the present inventors is sufficiently high, Ri great advantage there that can be produced in a single printing step, the layer of the resin single layer It is composed of a structure.

  In the present invention, a vertical color line and / or identification character / symbol made of a resin layer has an outer edge portion 3 ′ which is either a color of the vertical color line and / or identification character / symbol or a ground color of a hose. It is preferable that the resin layer is colored in a different color from the above, and the resin layer can be made to appear as if it is raised, and the visibility is further improved. Specifically, it is preferably colored in a dark color or dark color such as black, dark blue, or dark brown, or a relatively conspicuous chromatic color such as yellow, red, or blue. The outer edge portion 3 'may be formed as a simple colored portion having no phosphorescent property or retroreflective property. However, the vertical color line and / or the identification character / symbol has the retroreflective property and the luminous property. Since the fire hose has a good visibility similar to the letters when the fire hose is irradiated to a light or the like, it has a reflection characteristic and a phosphorescent characteristic like the letters and the like. It is preferable to form by.

Reference example 1
By using the transfer sheet method described above, a transfer sheet having retroreflective / light storage performance and a shielding coloring function was produced by printing each layer of a phosphorescent resin layer, a reflective layer, and a hot melt layer on the bead sheet.
