Description

Description: TECHNICAL FIELD The present invention relates to a plated body and a method for manufacturing the same, and in particular, afterglow that absorbs light energy to store light, and gradually releases this to emit afterglow. The present invention relates to a plated body and a manufacturing method thereof.

[Conventional technology]

Conventionally, fluorescent paint or phosphorescent paint is applied to a base material as a method of absorbing light energy of fluorescent lamps, mercury lamps, sunlight, etc., storing light, and gradually releasing this to generate afterglow. There is a method, and it is used for emergency exit signs and clock dials. However, the afterglow formed by such a coating method or the like has a hue that is limited to the hue of fluorescent paint or the like under the environment where light is irradiated, and can be used for ornaments and the like. It wasn't something.
Further, all of those surfaces are insulators, and one having conductivity has not yet been devised.

Then, in order to solve such a problem, the present inventor has worked on realization of a plating layer having a new function by developing an afterglow plating layer having a structure in which particles emitting afterglow are incorporated in a plating metal layer. A conventional study example will be described below with reference to FIG.

In the figure, 21 is a Cu plate (base material) which is a base metal, and an afterglow plating layer 22 is adhered to the surface thereof. The afterglow plating layer 22 includes a ZnS / Cu particle 2 on a Ni layer 23 that is a plating metal layer.
4 is buried, and the ZnS / Cu particles 24 are obtained by adding a very small amount of Cu as an activator to ZnS which is a sulfide phosphor.

When such afterglow plating layer 22 is irradiated with the light of a fluorescent lamp, the light energy thereof is absorbed and accumulated in the ZnS.Cu particles 24. After stopping the light irradiation, ZnS / Cu particles 2
4 gradually emits this and emits a green afterglow.

Such an afterglow plating layer 22 is formed by adding ZnS / Cu to the Ni plating solution.
In the afterglow plating solution prepared by dispersing particles 24, Cu plate 21
Is used as a cathode to perform plating. Here, as the ZnS.Cu particles 24, a phosphorescent pigment LC-GIA manufactured by Shin Loihi Co., Ltd. was used.

[Problems to be Solved by the Invention]

However, in the above-mentioned afterglow plating layer 22, the portion capable of receiving the irradiated light is limited to the partial surface of the ZnS.Cu particles 24 exposed from the surface of the Ni layer 23. Moreover, the Ni layer 23 has grown to cover the surface of the ZnS / Cu particles 24, and most of the ZnS / Cu particles 24 are not exposed from the surface of the Ni layer 23 and are completely buried. -The exposed area of the Cu particles 24 is extremely small. Therefore, the amount of energy absorbed and stored is low, and the brightness of the afterglow is extremely low.

In order to eliminate such problems, plating conditions and
Even if the particle size of the ZnS / Cu particles 24 was changed, sufficient afterglow could not be obtained.

In view of the above problems, the problem of the present invention is that a large number of afterglow particles are buried in the state of being exposed from the surface of the plated metal layer, and irradiated light can be stored on all surfaces of the afterglow particles. It is an object of the present invention to provide an afterglow-plated body which adheres an afterglow-plated layer to emit afterglow of high brightness and has a surface of the afterglow-plated layer having electrical conductivity, and a method for producing the same.

[Means for solving the problem]

In order to solve the above problems, means taken in the afterglow plating treatment body of the present invention, the plating metal layer deposited on the base material, a large number of afterglow particles of the state exposed from the surface is buried. The afterglow particles are composed of a powdery phosphor / phosphor which emits fluorescence or phosphorescence, and a light-transmissive resin layer coated on the surface thereof.

The plated metal layer of such an afterglow plated body is, for example, a metal layer composed of one or more metals selected from the group consisting of Ni, Ag, Cr and Sn.

Further, the phosphor / phosphor is a sulfide phosphor containing ZnS as a main component, and an activator comprising one or more metals selected from the group consisting of Cu, Ag, Pb and Mn. It is desirable to be added.

In such a method for producing an afterglow-plated body, the substrate is coated with afterglow particles in which the surface of a powdery phosphor / phosphor that emits fluorescence or phosphorescence is coated with a light-transmitting resin layer. A step of immersing a base material in an afterglow plating solution prepared by dispersing it in a plating solution containing at least metal ions of a plating metal layer to be deposited, and energizing the base material as a cathode while stirring the afterglow plating solution. At least.

Further, the above-mentioned afterglow particles are obtained by dispersing a powdery phosphor / fluorescent substance in a solution containing a light-transmitting resin, and then removing the solvent of the solution to form a solid. It is desirable to be manufactured by a step having at least a step and a step of crushing the solid material into a powder.

Furthermore, the afterglow particles must have a light-transmitting phosphor / fluorescent paint layer that emits phosphorescence or fluorescence between the powdery phosphor / fluorescent substance and the light-transmitting resin layer. Preferably, such an afterglow particle comprises a step of dispersing a powdery phosphor / fluorescent substance in a phosphorescent or fluorescent light-transmitting liquid phosphor / fluorescent paint, and then this The step of solidifying the liquid phosphor / fluorescent coating material, the step of crushing the solidified phosphor / fluorescent coating material into the phosphor / fluorescent coating powder, and then the light-transmitting resin described above. It is preferably manufactured by a step including at least a step of coating a layer.

[Action]

Afterglow particles in which phosphor-phosphor particles are coated with a light-transmissive resin layer are buried in the state of being exposed from the surface of the plating metal layer The light transmitted through the layer is absorbed / stored in the phosphor / fluorescent substance. The afterglow plating layer emits afterglow due to the stored light energy. Here, since the plated metal layer has not grown to cover the surface of the afterglow particles, the exposed area of the afterglow particles capable of receiving the irradiated light is large. Moreover, the received light reaches the periphery of the afterglow particles through the transparent resin layer and is stored in a wide area on the surface of the phosphor / fluorescent substance. Further, the emitted afterglow passes through the resin layer and reaches the surface of the plated metal layer, so that afterglow with high brightness is emitted.
The hue of the afterglow-plated body under light irradiation is the hue of the plated metal layer. In addition, since the periphery of the afterglow particles is a plated metal layer, the surface has electrical conductivity. Furthermore, since a part of the afterglow particles are buried in the plated metal layer, the fixation is reliable, and even if the surface of the afterglow particles is touched, the afterglow particles do not fall off and have high durability.

Further, such a phosphor / phosphor is a sulfide phosphor containing ZnS as a main component, which contains one or more metals selected from the group consisting of Cu, Ag, Pb and Mn. When added as an activator, the afterglow has a high brightness and the afterglow has a long duration. Moreover, the afterglow color can be freely selected depending on the type of activator, and for example, afterglow that exhibits green in the case of Cu, blue in Ag, blue-green in Pb, and orange in Mn can be obtained.

In the method for producing such an afterglow-plated product, when the substrate is plated in an afterglow plating solution in which afterglow particles in which a light-transmitting resin is coated on the surface of a powdery phosphor / phosphor are dispersed are dispersed. While the plated metal layer grows on the surface of the base material, the dispersed afterglow particles come into contact with the plated metal surface due to sedimentation or collision with the base surface due to stirring.
Adhere to. Then, the adhered afterglow particles are taken into the growing plating metal. Here, the surface of the afterglow particles is coated with a resin, and since the surface is an insulator, the plated metal layer does not grow on the surface of the afterglow particles. Therefore, the plated metal layer does not grow in a state of covering the surface of the afterglow particles, but grows in a state of surrounding the periphery, and fixes the afterglow particles with the afterglow particles being exposed from the surface. As described above, the afterglow-plated product having the above structure can be easily manufactured only by dispersing the afterglow particles in a general plating solution and performing the plating operation.

Further, such afterglow particles are obtained by dispersing a powdery phosphor / fluorescent substance in a solution containing a light-transmitting resin, removing the solvent from the solution to form a solid, and Since it is formed by crushing a solid material into powder, a structure coated with a resin layer can be easily realized.

When the afterglow particles have a phosphor / fluorescent paint layer between the phosphor / phosphor and the light-transmissive resin layer,
The irradiated light passes through the resin layer, reaches the entire afterglow particles, and is stored in the fluorescent / phosphorescent paint layer, and the light transmitted through this fluorescent / phosphorescent paint layer is phosphor / fluorescent. The light is stored in the light body. By this stored light energy,
The phosphor / phosphor and the phosphor / fluorescent paint layer emit afterglow, and the phosphor / phosphor causes phosphor / phosphor
Since the fluorescent paint layer further emits afterglow, it emits afterglow of higher brightness. Moreover, the hue of the afterglow can be set by selecting the phosphor / fluorescent paint layer, and the hue of the afterglow-plated body under light irradiation is the hue of the plated metal layer. Therefore, an afterglow-plated body having various functions can be obtained by combining the characteristics of the phosphor / fluorescent material and the characteristics of the phosphor / fluorescent coating layer.

Such afterglow particles are obtained by dispersing a powdery phosphor / fluorescent substance in a light-transmitting liquid phosphor / fluorescent coating,
By solidifying the phosphor / fluorescent paint and crushing this solid material, the resin layer is formed by the method described above,
It can be easily formed.

〔Example〕

Next, an afterglow-plated body according to an example of the present invention and a method for manufacturing the same will be described.

<First Example> An afterglow plated layer of an afterglow plated body according to a first example of the present invention will be described below with reference to Figs. 1 (a) and 1 (b).

FIG. 1 (a) is a conceptual diagram showing a cross section of the afterglow plating layer according to the first embodiment, and FIG. 1 (b) is an electron micrograph showing a surface state thereof at a magnification of 310 times. FIG. 1 (c) is an explanatory view of the electron micrograph.

In these figures, 1 is a Cu plate (base material) which is a base metal
The afterglow plating layer 2 is adhered to the surface thereof. The afterglow plating layer 2 includes a Ni layer 3 that is a plated metal layer, and afterglow particles 4 that are buried in a state of being exposed from the surface of the Ni layer 3.
The afterglow particles 4 have a small amount of Cu as an activator that should be the coloring center of luminescence, and are ZnS / Cu particles 5 that are sulfide phosphors containing ZnS as a main component, and their surfaces. And a light-transmissive fluororesin layer 6 coated thereon.

The afterglow plating layer 2 having such a structure has a silver-white color of the Ni layer 3, and when this is irradiated with light from a fluorescent lamp, the light energy thereof remains exposed from the surface of the Ni layer 3. The light particles 4 pass through the fluororesin layer 6 and are absorbed by the ZnS.Cu particles 5 to accumulate light. The stored light energy is gradually released after blocking the light of the fluorescent lamp, and emits a green afterglow for about 20 minutes at room temperature.

Here, the ZnS / Cu particles 5 are the transparent fluororesin layer 6
Since the irradiated light passes through the fluororesin layer 6 and reaches the entire circumference of the ZnS.Cu particles 5, the amount of light absorbed and accumulated is high. Further, the emitted afterglow passes through the fluororesin layer 6 and reaches the surface of the Ni layer 3. Therefore, afterglow with high brightness is emitted. Since the afterglow particles 4 are surrounded by the Ni layer 3, the surface of the afterglow plating layer 2 has electrical conductivity. Therefore, the portion requiring electrical conductivity can be modified into a surface emitting fluorescence. Further, the afterglow particles 4 are buried in the Ni layer 3 with a part thereof exposed from the surface of the Ni layer 3 and do not peel off or fall off, so that the durability thereof is extremely high. And
Since the ZnS / Cu particles 5 are used, the persistence of afterglow is long and the heat resistance is high, so that it can be used for a wide range of purposes.

A method of plating such afterglow plating layer 2 will be described below with reference to FIGS. 2A to 2C, which are sectional conceptual views of the afterglow particles 4.

First, as shown in FIG. 2 (a), a small amount of activator is used.
ZnS containing Cu containing ZnS / Cu particles with a particle size of 10 to 15 μm 5
Are dispersed in a volatile solvent containing a transparent fluororesin. The solution is then heated to remove the volatile solvent. As a result, as shown in Fig. 2 (b), ZnS ・ C
The u particles 5 are solidified by the fluororesin layer 6. Next, the solid matter is pulverized into a powder form, and afterglow particles 4 in which the surfaces of ZnS / Cu particles 5 are coated with a fluororesin layer 6 are obtained as shown in FIG. 2 (c). . Next, 30 to 40 g / afterglow particles 4 are mixed with the Ni plating solution to adjust the afterglow plating solution. Here, the Ni plating solution contains 300 g / of NiSO ₄ , 50 g / of NiCl ₂ , and 40 g / of H ₃ BO _3.
Is a liquid with a slight amount of brightener added, and its pH is 3.5-
It is 4.5. The afterglow plating solution adjusted in this way
Stirring is performed while maintaining the temperature at 5 ± 10 ° C., so that the afterglow particles 4 are dispersed in the afterglow plating solution. The Cu plate 1 is immersed in the afterglow plating solution in this state with the surface to be plated facing upward. When the Cu plate 1 is used as a cathode and the Ni plate is used as an anode, when electricity is applied, the surface of the Cu plate 1 is plated and a Ni layer 3 grows. Here, the afterglow particles 4 dispersed in the afterglow plating solution are brought into contact with the Ni layer 3 growing on the surface of the Cu plate 1 by sedimentation and agitation, and adhere and grow together.
It is taken into the Ni layer 3. At this time, since the surface of the afterglow particles 4 is coated with the fluororesin layer 6 and the surface of the afterglow particles 4 is insulative, the Ni layer 3 does not cover the surface of the afterglow particles 4, It grows around the afterglow particles 4. Therefore, the afterglow particles 4 are taken into the Ni layer 3 while being exposed from the surface of the Ni layer 3 to form the afterglow plating layer 2. The afterglow particles 4 are ZnS / Cu.
Since the surface of the particle 5 is coated with the fluororesin 6, the Ni layer 3 is prevented from growing and covering the surface of the particle 5, and the specific gravity of the afterglow particle 4 is reduced so that the afterglow in the plating solution is reduced. The particles 4 are easily dispersed. In this example, the phosphorescent pigment LC-GIA manufactured by Shin Loihi Co., Ltd. was used as the ZnS.Cu particles 5.

The light energy absorbed and stored in the fluorescent paint layer 16 around the entire circumference thereof is further absorbed by the ZnS.Cu particles 15 and stored therein. Due to the stored light energy, the afterglow plating layer 12 emits red afterglow which is the fluorescent color of the fluorescent paint layer 16.

Here, since the afterglow particles 14 are coated with the light-transmitting fluorescent paint layer 16 and the light-transmitting acrylic resin layer 17, the irradiated light passes through these layers, and the fluorescent paint layer. 16 and the entire circumference of the ZnS.Cu particles 15 are reached.
In addition, the emitted afterglow transmits through these layers and the Ni layer 13
To reach the surface of. Moreover, since the fluorescent paint layer 16 emits more afterglow upon receiving the afterglow emitted by the ZnS / Cu particles 15, the afterglow has a higher brightness and the afterglow color is the red afterglow of the fluorescent paint layer 16. It exhibits a light color. As described above, while exhibiting the hue of the Ni layer 13 under light irradiation, by combining the ZnS / Cu particles 15 and the fluorescent paint layer 16, a long-lasting, high brightness, afterglow plating layer capable of selecting an afterglow color You get 12. In addition, the surface thereof has electrical conductivity, and since the afterglow particles 14 are fixed in the Ni layer 13 with a part thereof buried therein, the afterglow particles 14 have high durability and high heat resistance.

Here, the Ni plating solution has the same composition as in the first embodiment, and contains NiSO ₄ , NiCl ₂ , H ₃ BO ₃ and a brightener. The afterglow plating layer 12 can be formed by performing plating in the same manner as in the first embodiment using the afterglow plating solution thus adjusted. Here, since the afterglow particles 14 are coated with the fluorescent paint layer 16 and the acrylic resin layer 17, the surfaces thereof are insulated and the afterglow particles 14
