Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an expression system based on dispersion of a phosphorescent material having afterglow characteristics in a transparent medium material, and more particularly to a composite body containing the phosphorescent material in the transparent medium material.

[0002]

2. Description of the Related Art A phosphorescent material is a kind of fluorescent material, and the principle of its light emission is that light energy increases the energy from a ground state to an excited state, and when the excited state returns to the ground state, light is emitted at that energy. Among them, the phosphorescent material has a property of emitting phosphorescence (afterglow) for a long time in a dark place because it takes a long time to return from an excited state to a ground state among phosphors.

Luminescent materials have various advantages not found in conventional materials such as luminous paints.
Since it is a non-radioactive substance and is extremely safe, it has an advantage, and its range of application is expanding compared to conventional luminescent materials.

Further, the light-storing material has a long light emission time in the dark, and by utilizing this characteristic, it can be used as an emergency light or an emergency light.
In addition to those that improve safety such as safety signs for clothing, watch dials, instrument display boards, fishing lures, etc. to improve functions, printed products, glass and ceramic products, textile products, etc. It has been used for various purposes such as improving decorativeness.

By the way, as a means for applying the phosphorescent material to various articles, finely divided phosphorescent material is dispersed in a paint solvent and the paint is applied to a predetermined place, or the phosphorescent material is finely granulated. The object is achieved by uniformly dispersing the converted product in the resin.

In addition, resin, film, board, fiber,
It is dispersed in materials for various uses such as paints and inks, and achieves the purpose as a phosphorescent material.

[0007]

However, the above-mentioned phosphorescent material has been relatively expensive as compared with many other general-purpose materials since its introduction until the present.

For this reason, it has been devised so that it can be efficiently used without impairing its inherent characteristics (light storage characteristics).

For example, when a phosphorescent material is introduced into a paint, it has many physical properties that are not found in ordinary paint materials. Therefore, by uniformly dispersing fine particles of the phosphorescent material in a paint solvent, it is possible to obtain a paint. It is desirable that the quality is exhibited more, and it is necessary to add the light-storing material in the state of pigment powder into the solvent to make it into a paint while devising measures for dispersion and sedimentation.

Even when the phosphorescent material is put into a transparent medium such as a resin, the phosphorescent material must be carefully dispersed in order to maintain the quality of the material, and sedimentation in the resin causes distribution of the material particles. Was not allowed to be unevenly distributed.

In addition, when processing a normal phosphorescent material,
In most cases, the phosphorescent material is put into the resin material in the form of pigment powder, and it is made into resin while devising measures to prevent dispersion and sedimentation, or it is further crushed, cut, and bent in the state of secondary processing material. Was going on.

As described above, in order to satisfy the condition of uniform dispersion of the phosphorescent material, the above-mentioned object has been achieved by using a phosphorescent material which is as finely granulated as possible. There is a drawback in that the brightness, which is a characteristic of the light-storing material, decreases with the decrease.

Conventionally, acrylic and vinyl chloride type synthetic resins have been mainly used as a transparent medium material used together with a light storing material. In the case of glass type materials, fine glass is used in the vicinity of 600 ° C. which is the glass processing temperature. Deterioration of the granulated light-storing material due to oxidation or the like starts, and almost 900 degrees C or more of the light-storing material deteriorates or becomes vitrified (transparent) at around 900 ° C., and the characteristics of the light-storing material cannot be utilized.

For the above reasons, the luminescent material manufacturers have so far called for not to use glass directly as a medium material for the luminescent material because it causes deterioration of the luminescent property. It was In addition, the trial case was not realized as a product because the amount of the phosphorescent material was extremely large.

Further, the light storing material itself is a light emitting material,
Since it is present in the paint or resin in a dispersed manner, the painted product or the material product itself becomes a luminescent indicator, and it was originally desired to obtain the expression system by painting or the material product. It was processed separately and used as a luminescent marking.

Naturally, the luminous property itself was not required to have a design property, and it was merely used as a raw material of a material that was expected to have a design property.

That is, conventionally, in order to maintain the characteristics of the light-storing material, fine powders of these light-storing materials have been uniformly dispersed in the coating or resin, and moreover, the transparent field and the transparent space portion are When they occurred, these were regarded as defects in processing due to incomplete dispersibility.

Due to the above-mentioned circumstances, not only did the design of the combination of the light-storing material and the medium material not occur, but in the first place, the transparent field of the transparent medium material itself, and the transparency-proprietary portion were expressed by combining it with the light-storing material. Until now, the idea of expression fields and functionalization that entrusts the system did not exist.

Also, regarding the brightness of the light-storing material, the expected brightness was realized by the total amount of the raw material powder thrown into the resin or medium (medium) in the individual powder material itself, but this is always the case. Consumers felt that the ability of the phosphorescent material for basic performance was insufficient.

Furthermore, although the use of aluminum oxide phosphorescent materials has been attempted to expand the applications throughout the industry so far, it is a new raw material, but after 8 hours, the emission luminance is 5 mcd (millicandela) / m ² or more. It has been expected that the feasibility will be extremely difficult, such as targeting.

With respect to this target as well, it is difficult to realize a conventional coating material or resinification method as a powder raw material, and even if it is realized, controllability is low and highly accurate reproduction is difficult to expect. Met.

The present invention solves the above problems,
To meet the demands of customers by using a new expressive power by combining a phosphorescent material and a transparent medium material, and a particle size range in which higher luminous energy can be expected without impairing the light emitting ability with high physical properties, which is the basic performance of the phosphorescent material. The task is to provide an expression system that can be provided.

[0023]

In order to solve the above problems, the invention of claim 1 provides a transparent medium material having at least a particle size of 2 or more.
This is an expression system in which a luminous material is dispersed in a transparent medium in which a luminous material having a diameter of 00 μm or more is arranged.

According to the invention of claim 2, the arrangement of the phosphorescent material expresses a design meaning such as a character, a figure, a symbol, or a three-dimensional shape, and the phosphorescent material is dispersed in the transparent medium material according to claim 1. It is an expression system.

As the transparent medium, a medium having high transparency such as various synthetic resins such as acrylic, polyester, silicon, polycarbonate epoxy, melamine, polyethylene, polypropylene, polystyrene, etc. other than glass is generally used. Is.

Of course, as the transparent medium material, any material other than the above-mentioned materials can be used as long as it can realize the expression system in the scope of the claims, and when realizing the expression system, the transparent medium material is a resin material cured as a resin material. Not only that, the expression system may be maintained even in a gel state or a fluid state, and for example, a transparent medium material having fluidity such as water paste or liquid resin is also included.

The phosphorescent materials in the present invention include all materials generally called phosphorescent materials, including those based on aluminum and those based on sulfides, and in recent years, exhibit extremely high emission brightness. Aluminum oxide-based, hydroxide-based, and chloride-based light-storing materials, including long-term afterglow light-storing materials that have a peak of emission wavelength in the visible light region, have become popular rapidly in recent years. An afterglow phosphor containing strontium as a main component is exclusively used.

However, in the present invention, any of the raw material phosphorescent materials has desired emission luminance and afterglow performance, and the material requirements necessary for the expression system of the present invention and the particle size based on the design required for design expression are It's okay if it can be realized,
It does not reject various phosphorescent materials such as chloride-based materials that appear one after another, and is not bound by the composition of formation or the processing method.

In addition, due to the distribution of the wavelength band in the visible light range emitted by the phosphorescent material, the materials for which the currently visible luminescent impressions have respective luminescent colors such as green, blue, blue green, violet, orange and red have been developed. Has been done. However, in this invention, the luminescent color of the luminescent material is not particularly limited, and any luminescent color of all the luminescent color materials may be used as long as it is a luminescent color that satisfies the design requirements as an expression system and the expression requirements according to the requirements of the design. It is possible to optionally use some materials and all, or a plurality of emission colors realized now or in the future.

As the phosphorescent material, it is possible to use a material that has not been subjected to processing such as ink, paint, film, etc. or modification treatment in advance. It does not deny any treatment or allowance made to adapt.

However, the reason why the present invention can be expected to have remarkably high performance as compared with the conventional one in which a composite of a phosphorescent material formed into an ink, a paint, or a film is inserted is that the particles of a phosphorescent material that have been carefully examined and arranged are arranged. It is characterized by extremely high brightness and long afterglow time by realizing an expression system that is realized by using, and arranging another material in which phosphorescent powder is dispersed in advance without inserting or intermediating. Specifically, 1.5
It is an expression system that can maintain a brightness of at least 7.5 mcd / m ² or more even after a lapse of time.

In particular, in the examples of the present invention, an expression system capable of maintaining a brightness of 15 mcd / m ² or more after 8 hours could be obtained.

The size is 20 before the fine grain processing.
As a phosphorescent material of 0 μm or more, especially a particle size of 500 μm or more is suitable in terms of brightness and strength during processing, and the number of particles of the phosphorescent material may be one or more in the transparent medium material. Besides, a phosphorescent material having a particle diameter of less than 200 μm may be included.

The brightness at the time of phosphorescence is not particularly limited, but the emission brightness is 7.5 m after 90 minutes of measurement brightness.
Those having the ability to measure cd (millicandela) / m ² or more are preferable.

The arrangement of these phosphorescent materials in the transparent medium is 200 μm by crushing and dividing the phosphorescent material into coarse particles.
Each of the above-mentioned arbitrary particle sizes is arranged in a solid transparent medium material or in a transparent medium material in which fluidity is maintained, according to a desired design.

Although the expression system is arranged in a fluid transparent medium material, it does not deny that the expression system is arranged dynamically according to a predetermined design and program for dynamic behavior in the fluid medium material. Absent.

At this time, according to the present invention, not only resin but also 9
Even when a glass-based material treated at a temperature of 00 ° C. or higher is used as a transparent medium, by using a phosphorescent material having a particle size of 200 μm or more, preferably 500 μm or more, it is difficult to be affected by temperature and the In the glass, the luminous properties and the brightness can reach the purpose.

Also, by selecting the particle size of the light-storing material contained in the transparent medium material to 200 μm or more, it is possible to realize a high brightness expression system in the transparent medium material. It can be realized regardless of whether it is two-dimensional or three-dimensional, such as design, art design, and various copyrighted works.

Further, by containing a light storing material having a particle size of 200 μm or more, preferably 500 μm or more, the strength of the transparent medium material is improved and the material fastness is improved.

It should be noted that substances other than the light-storing material, that is, materials such as ink, paint, dye, resin, film, and other expression systems may be mixed in the transparent medium.

Since the phosphorescent material is a self-luminous material and has a characteristic that energy must be supplied from the outside in order to emit light, its presence in the transparent medium means from the viewpoint of light emission and energy supply. It was important.

Conventionally, when it is used as a light-storing material in a transparent material, it is a cloth for accommodating a coating film, a coating film as a barrier from the outside air, or imparts a colored afterglow property. The purpose was to protect and support the ability of the phosphorescent material.

However, in the present invention, the direct transparent medium itself has a new expression system together with the light storing material having a particle diameter of 200 μm or more which is present therein.

That is, since the phosphorescent material having a particle size of 200 μm or more maintains the brightness in the transparent medium, the phosphorescent material expresses characters, numerical values, symbols, various designs, art designs, various works and the like. Therefore, it is possible to express differently from the conventional one in which the light-storing material has fine particles uniformly dispersed in the medium.
