First, the above-mentioned <A> will be described. In the present invention, the light energy of illumination such as sunlight or fluorescent light is absorbed and accumulated. Therefore, in order to utilize the light-emitting functions of a phosphorescent material that emits light under night vision and a fluorescent material that emits light by ultraviolet irradiation as a change in hue, It is essential that phosphorescent and fluorescent materials be used together.

In this case, the phosphorescent or fluorescent material may be an inorganic or organic material, but the durability and abrasion resistance, as well as the phosphorescent and fluorescent materials, may be used. It is usually preferable to use an inorganic material from the viewpoint of the optical characteristics of the light material and its sustainability.

Examples of such inorganic materials include strontium aluminate, oxides of rare earth activated aluminum, and oxides such as strontium. Substances, other various oxides, sulfides such as zinc, barium, and stronium, or their activating substances. Become .

As for the resin, it is a thermosetting resin such as acrylic resin, methyl resin, epoxy resin, unsaturated polyester resin, and some of them. Something is preferred. The inorganic material itself serves as a base material or as an aggregate or as a binder, and the resin is also the same. .

For example, cement, glass, etc. are used as binders, and the fines and fines are used as aggregates. It is something. On the other hand, natural stones, ceramics, and metals are used as their own base materials, or their fine particles of pongee are used as aggregates. .

Regarding the specifications of the phosphorescent or fluorescent material to be implanted or inserted, the following are examples of the relationship with the base material. .

1) A phosphorescent material or a fluorescent material is injected into the base material component as a mixed component.

It is mixed with a base material component and formed into a plate-shaped body, a block-shaped body or the like having a predetermined shape.

In this case, natural stones, tiles and other ceramics, glass and other powdery and granular materials, and slag and inorganic fibers are aggregate components. Thus, the base material can be formed. In the case of using these aggregate components, if resin is used as a binder, artificial stone will be formed.

1-2) In addition, for this driving, the base material that has been formed in advance has grooves, holes, etc., and the phosphorescent material is Alternatively, the fluorescent material is poured in a mixed state with resin, glass, cement, etc. as a binder and cured. It is also realized by this.

1 1 3) Driving may be the reverse of the above. In other words, the phosphor and the fluorescent material are molded together with a binder and the like into a predetermined shape, and this is integrated as a part of the entire product. This is also realized by the fact that the base material component is cast as a mixture in the form of a mixture and cured.

No. For example, it may be for an electromagnetic shield. It may be integrated with various components for construction and installation as house building materials.

In the present invention, it is indispensable that the color tone of the base material is controlled to a predetermined value. This is

① Color under normal conditions such as sunlight or fluorescent lighting

② The color of light emitted by the phosphorescent material under the field of view such as at night

(3) This is because it is possible to change the three phases between the color of light emitted by the fluorescent material and the color of the light emitted by ultraviolet irradiation.

Regarding the color tone of the base material itself, depending on the color embodied in the base material itself, or with respect to the base material, an inorganic or organic pigment may be used. It is realized by adding and blending dyes and dyes.

Hereinafter, the case of forming artificial stone will be described in more detail as a preferred embodiment of the internal and external materials of the present invention.

GU Artificial stone inside and outside materials>

The composition of the artificial stone can be, for example, a material containing an inorganic material as an aggregate and a resin as basic components. In this case, the inorganic materials include a wide range of materials such as natural stones, natural minerals, artificially synthesized inorganic materials, glass, and metals.

In the light emitting section, a fluorescent material is used as a phosphorescent material as at least a part of or all of the inorganic aggregate. <Composition of the light emitting part and the base material integrated with the light emitting part> The light-emitting part, or the base material in which the light-emitting part is dispersed and integrated, contains a resin containing a phosphorescent material and a fluorescent material, but also contains a transparent inorganic aggregate. You may do it. When this transparent inorganic aggregate is contained, the weight ratio of the two is 1: 2 to 1:10, and the sum of the two is 80 to 95 weight of the entire composition of the light emitting part. It is preferable to make it a percentage.

Also, a transparent inorganic aggregate having a surface-baked coating made of a phosphorescent material and / or a fluorescent material may be contained. It is preferred that it be 5 to 65% by weight of the total weight based on the composition weight.

In terms of physical properties such as peeling resistance, falling resistance, and abrasion resistance, and luminous performance, the above-mentioned composition is preferred.

As the inorganic aggregate, a combination of the following two types is preferable, and examples thereof are given as examples. That is, one is an inorganic fine-grained component with a size of 5 to 70 mesh, which is used for silica, olivine, feldspar, pyroxene, mica, etc. It is an appropriate inorganic fine-grained component selected from minerals, natural stones such as granite and metamorphic stones, ceramics, glass, and metals.

In addition, the fine grain component of the 100 mesh under is preferably used together with this pongue grain component. Examples of the fine particles include various natural or artificial fine particles. For example, calcium carbonate, aluminum hydroxide, silica powder, etc. are easily obtainable fine particles.

In addition, as part of this fine particle component, components such as manganese dioxide, titanium dioxide, zirconium silicate, and iron oxide for adjusting color tone, and flame retardant Z trioxide to provide non-combustibility (pentic acid) Components such as antimony, boron compounds and bromine compounds may be added and blended.

The fine grain component functions as a major factor in the appearance and physical properties of the obtained artificial stone molded product. The fine particles are finer than the 100-mesh level compared to the pongee particles, and penetrate into each of the pongee particles to fill the space between the particles. It contributes to obtaining the properties of the resulting artificial stone, such as hardness and flexibility. The fine-grained component and the fine-grained component are preferably in a weight ratio of 0.5: 1 to 5: 1, and more preferably 1: 1 to 4: 1. In the case of forming an artificial stone compact as a combination of a fine-grained component and a fine-grained component, the structure of the light emitting portion can be considered as follows.

That is, when a luminous substance, and a fluorescent substance and a transparent inorganic aggregate are used as a part of the inorganic aggregate, in this case, at least one of fine particles is used. It is preferable to use a transparent inorganic component as a part, and use a phosphorescent material and a fluorescent material as at least a part of the fine particle component.

The fine-grained component as a transparent inorganic aggregate means that it is a substantially light-transmissive inorganic component, and the degree of transparency varies. However, inorganic substances that have relatively high light transmittance in natural or artificially synthesized inorganic substances can be used in the present invention. For this reason, the transparent inorganic fine-grained component may be in a colored state or in a state having a unique color.

Typically, quartz stone, silica stone, glass, etc. are used in the present invention. Examples of the transparent inorganic fine particle component include, but are not limited to, these.

Artificial stones contain 100 luminous phosphorescent and fluorescent materials as part of the fine particles. Representative examples of such components include, as described above, strontium aluminate-based phosphorescent materials, zinc sulfide, and the like. These various materials will be used in the present invention.

The inorganic fine-grained component that plays a role as an aggregate of artificial stone has a size in the range of 5 to 70 mesh as described above. This is an essential requirement in combination with inorganic fine particles. In the case of the above-mentioned phosphorescent or fluorescent material, it plays a role similar to that of the fine particle component and also imparts an optical function to the artificial stone. . It is indispensable that the size of the phosphorescent material or the fluorescent material should be 100 mesh as well as the fine particles.

Regarding each of the above-mentioned inorganic components, the size and the proportion of the components are important requirements.

That is, the weight (W,) of the inorganic fine particle component, the weight (W ₂ ) of the inorganic fine particle component, and the weight (W ₃ ) of the phosphorescent or fluorescent material component The relationship is

W,: (W 2 + W 3) = 0.5: 1 to 5: 1

W 2: W ₃ 2 1: 2 to 10: 1

It is preferred that

W! : (W 2 + W 3) is more preferably about 1: 1 to 4: 1, and W ₂ : W 3 is about 1: 1 to 5: 1. Is more preferred. As described above, for the inorganic fine particle component, the ratio of the transparent inorganic fine particle component is as follows.

(0.5 to 1.Q) W

It is desirable to have a relationship.

The above is required for the physical properties of artificial stone, such as strength, hardness, and density, and for the realization of optical functions.

The size of each component is specifically selected according to the size and the mixing ratio of each component to be combined. In general, the phosphorescent or fluorescent component is more preferably in the range of about 150 to 250 mesh.

To further explain the light function of the artificial stone, the light function of the artificial stone of the present invention is as follows.

1) 30 to 100% by weight of the inorganic fine particles should be used as the transparent inorganic fine particles

2) By blending the components of the 100-meshunder luminous material and the fluorescent material in the specific proportions as described above, the luminous properties are improved. It can be realized as an artificial stone having the light function of luminescence or luminescence with fluorescence. The feature in that case is that light emission is enabled as a thickness. Instead of emitting light only at the surface layer as in the past, the light is emitted over the entire thickness of the artificial stone, and the light emitting performance is excellent, and the expensive phosphorescent material or fluorescent material is used. It is also economical to use the wood components.

This is a transparent inorganic fine-grain component as a transparent aggregate. Due to the use of sunlight, sunlight and light emitted from the outside penetrate and penetrate into the artificial stone, and the light energy is efficiently stored in the night storage material or fluorescent light. Since the light-emitting layer, which is absorbed by the components of the material and in which the phosphorescent material is dispersed, has a large thickness including the interior of the artificial stone, it can be used for a long time with high luminosity. This is because it is possible to maintain At the time of light emission, the transparent inorganic fine particle component has a high luminosity due to its good light transmittance.

The ratio of the transparent component to the total fine component is as described above.

The weight is 30 to 100%, but depending on the physical properties such as the strength of the artificial stone and the appearance and design, the proportion is preferably 100%. This is natural. Of course, it is not limited to this, but if it is less than 30%, it will be difficult to obtain the required optical function.

The fine-grained component when using a transparent inorganic aggregate surface-baked with a phosphorescent or fluorescent material as a part of the inorganic aggregate In the invention, at least a part of the transparent material is baked with a phosphorescent material that emits light, which also absorbs ultraviolet light, because at least a part of the material is transparent. It can be used as a service. That is, a part or the whole of the fine-grained component is a transparent inorganic aggregate whose surface is coated with a phosphorescent material and Z or a fluorescent material. As a fine particle component as such an inorganic aggregate having a transparent light, glass-silicaite is exemplified as a preferable one.

Regarding the pongee components to be incorporated into the composition, the proportion (weight) of 10 to 100% of the composition is determined by the aforementioned phosphorescent and / or fluorescent materials. Preferably, it is a transparent inorganic aggregate having a surface coating layer of

In the case of a transparent inorganic aggregate, especially a baking coating of fine-grained components, the surface of the particles of the transparent fine-grained components is several m to several tens / m, for example, 5 to 50 m, more preferably. Or a coating of about 20 to 40 / m. More specifically, the coating can be applied by baking at a high temperature of about 120 to 1200 ° C.

The phosphorescent or fluorescent material to be baked may be a substance such as strontium aluminate or zinc sulfide.

Baking is not a conventionally known various method. For example, a dispersion in which powdery particles of a phosphorescent material such as strontium aluminum phosphate are dispersed is used. Alternatively, the transparent inorganic aggregate, for example, the above-mentioned fine particle component can be mixed in the paste, dried and baked.

As described above, it is desired that the size of the inorganic fine particle component is also a specific one. That is, the inorganic fine particle component has a size of 5 to 70 mesh as described above. When you want to add a color to the top or bottom using a colored object or a colored object, the size of the finer particles depends on the presence or absence of the color. It is conceivable that the product may be used differently, but the use of a large amount of extremely different products should not be used because it will degrade the strength of the product.

On the other hand, the particle size of the fine component is set to 100 mesh as described above. It must be able to penetrate sufficiently between the particles of the fine components. More specifically, 150- A thing of about 250 mesh is preferable.

Further, the resin component can be selected in a wide range from thermosetting ones.

For example, acrylic resin, methyl resin, epoxy resin, unsaturated polyester resin, combinations thereof, and the like are exemplified. These can be homopolymers or co-polymers. Among them, point strengths such as transparency, hardness, strength, etc., are shown as those in which a methacrylic resin or an epoxy resin or a combination thereof is suitable. The mixing ratio of the resin component is preferably less than 15% by weight of the whole composition and more preferably 10% by weight or less. This resin component wraps the fine-grained component and fine-grained component, which are the components that form the skeleton described above, and contributes to binding the whole, thereby completing the artificial stone. At the same time, it has the function of giving the product elastic or tensile strength. The ratio of the amount of the inorganic aggregate composed of the fine component and the fine component is limited. Chi I sand, Razz Do if Kere, such more than 8 5% in weight ratio, Ri products Do rather brittle and virtuous or to rather than the more than Oh Ru o ⁷ by yourヽ9 5% 8 9% or more, use Unfortunately, you can only get things. In addition, if the content is less than 85%, the product is too soft to have a stone-like property, and the range of use is similar to that of the resin plate.

This is because fine components such as natural stones and components other than fine particles, that is, resin components, are present in the product at most in a weight ratio of 15% or more. It will not happen.

If the resin component exceeds about 15%, the product becomes plastic, and the artificial stone is no more than a name. In addition, excessively low levels of the resin component may affect the natural color of the product. There is a surface that increases the appearance close to that of, but the product becomes brittle and becomes unsuitable for use. From such a viewpoint, the resin component is more preferably set to be 5 to 11% by weight.

The normal colors of the internal and external materials of the invention as artificial stones are, as is clear from the above, the type of the inorganic aggregate to be blended, the particle size and the blending amount. However, it is also adjusted by blending another pigment, dye or the like with the resin component.

Such pigments include inorganic pigments such as calcium carbonate, barium sulfate, zinc oxide, titanium oxide, and yellow pigments in white pigments. Rom yellow, cadmium yellow, reddish iron oxide (bengala), power domed red (sulfide), molybdenum (Oxides), blue-colored, black (oxide), etc., and organic-based, various yellow-red azo pigments, blue-green Phthalocyanine-based pigments, and quinacridone-based, perylene-based, isoindolinone-based, quinophthalone-based pigments, etc. Illustrated as what can be used.

In addition, various types of dyes are appropriately used.

In the case of artificial stone, the composition of the resin and the inorganic material can be almost the same as described above.

For example, the base material is roughly divided into three components. One is an inorganic fine-grained component with a size of 10 to 70 mesh as the main component, which is composed of quartzite, olivine, feldspar, pyroxene, cloud Minerals such as mothers, natural stones such as granite and metamorphic rocks, and appropriate inorganic fine-grained components from ceramics, glass, metals and the like are used.

In addition, the fine-grained component of 100 Meshunder is used together with the fine-grained component. Examples of the fine particles include various natural or artificial fine particles. For example, calcium carbonate, aluminum hydroxide, and the like are easily obtainable fine particles.

Also, as part of this fine particle component, components such as manganese dioxide, titanium dioxide, zirconia silicate, and iron oxide for adjusting the color tone, and flame retardant A component such as antimony trioxide, a boron compound, or a bromine compound may be added for the purpose.

The third component is a resin component. The resin component can be selected from a wide range of thermosetting ones.

For example, the same acrylic resin, methyl acrylate resin, epoxy resin, unsaturated polyester resin and the like as described above are exemplified. Among them, from the viewpoints of transparency, hardness, and strength, a resin such as a methyl resin and an epoxy resin is preferable.

Fine-grained components such as natural stones function as major factors in the appearance and physical properties of the resulting artificial stone. In particular, the exposure of a part of the material, along with other components, is a major factor in the appearance of colors and patterns.

The fine-grained component is considerably finer than the 100-mesh level compared to the fine-grained component, and penetrates between each fine-grained component to fill the space between the fine-grained components. In this way, the weight ratio of the tsumugi-granule component and the fine-grain component that contributes to obtaining the properties such as the hardness and flexibility of the resulting artificial stone is It is preferable that the ratio be 0.5: 1 to 5: 1. In addition, the resin component wraps the fine-grained component such as natural stone or the fine-grained component, which is a component forming the above-mentioned skeleton, and binds the whole. It has the function of imparting elasticity or tensile strength to the product when the artificial stone is completed.

In the present invention, the composition ratio of these components is important. Particularly important is the composition ratio of the resin component to other components. The invention has a dense structure. One of the features is that high-density products are possible. Here, high-density means that the fine-grained components and fine-grained components contained in artificial stone products are high. It means that it exists in the density, which is more than 2.2 gcm ³ , which is beyond the range of conventional artificial stones. .

In other words, the composition ratio of fine-grained components such as natural stones, which are the skeleton components, in products is almost as close to natural stones as possible, but when they are too large, they are solidified. First of all, it cannot be used as a product. Also, the physical properties of the resulting product are poor and cannot withstand normal use.

Also, in addition to causing inconvenience such as not being hardened even if a large amount of fine particles are used, what is obtained is not glossy. It will be a good thing.

Accordingly, the proportion of the fine-grained component and the fine-grained component used is limited. That is, it must be at least 85% by weight, and preferably at least 90%. If the content exceeds 95%, the product becomes brittle, making it difficult to use, and only obtaining good results. On the other hand, if it is less than 85%, the product is too soft to have a stone-like property, and the range of use is similar to that of the resin plate. This is because fine components such as natural stones and components other than fine particles, that is, resin components, are present in the product at most in excess of 15% by weight. This is what happens.

If the resin component exceeds about 15%, the product becomes plastic, and the artificial stone is no more than a name. Too little resin component may increase the appearance of the product close to its natural color, but it also makes the product brittle and unsuitable for use. . Such a viewpoint, more preferably, the resin component is set to be 3 to 10% by weight. <Then, the artificial stone composition according to the present invention is used. In artificial stones as products and products, some or all of the above-mentioned inorganic fine-grained components are transparent particles. Even if the nodules are coated with inorganic or organic matter, they may be.

Such a coating of the transparent fine-grained component may be obtained by coating and curing a resin on the surface of the transparent fine-grained component, or by using a water glass or a ceramic glaze. This is achieved by baking and coating an inorganic substance such as a phosphorescent material or an ultraviolet absorbing fluorescent material. In any case, the surface of the transparent fine-grained component has a surface of several m to several tens of m, for example, 5 to 50 / m, more preferably about 20 to 30 m. Make sure that the coating is applied. More specifically, for example, an acrylic resin, a methyl acryl resin, an epoxy resin, or an unsaturated polyester resin composition is used. Heating to about 100 ° C or irradiating light to coat and cure these resin compositions on the particle surfaces of fine-grained components, or use water glass 800 to 110 ° C using a glaze Can be baked at moderately high temperatures to provide an inorganic coating

These coatings greatly improve the affinity of the fine-grained component, which functions as an artificial stone aggregate, for the entire tissue. Further, by mixing the fine particle component and the resin component, the strength is increased and the surface hardness is also improved.

The fine-grained component is made of the above-mentioned transparent natural stone, etc., and the hard coating is applied to the surface. This coating layer is likely to be broken. As a result, the surface texture of the partially exposed inorganic transparent particles and the surrounding coating layer has a special effect on light reflection.

In other words, light enters the transparent fine-grained component, is reflected by the surrounding coating layer, passes through the transparent fine-grained component again, and is reflected. Such transmission and reflection phenomena are fundamentally different from the reflection only on the surface of the conventional artificial stone, and give the artificial stone product of the present invention a unique sense of depth. It will be. The transparent fine-grained component, which has a coating layer more than that for obtaining a thick, high-quality, marble-like artificial stone, is the inorganic fine-grained component to be added to the composition. The total amount can generally be in the range of 10 to 100%.

In this invention, it is necessary that the size of the inorganic fine-grain component is also specified. That is, the inorganic fine particle component has a size of 10 to 70 mesh as described above. The size of fine grains depends on the presence or absence of color, for example, when you want to add a color to the top or bottom using a colored object or a colored object. It is conceivable to use a different type, but it is not advisable to use a large amount of extremely different ones because it will reduce the strength of the product.

On the other hand, the size of the particles of the fine component is set at 100 mesh as described above. It must be able to penetrate between the fine particles. More specifically, those having a size of about 150 to 250 mesh are preferable.

Furthermore, what is important in the high-density artificial stone as an embodiment of the present invention is that, except for special cases, these material compositions are uniform in any product part. It is hoped that they are distributed in

As can be seen from the above, the colors of the inner and outer materials of the present invention as artificial stones at normal times are determined by the type of inorganic aggregate to be blended and the particle size and blending amount. However, it is also adjusted by blending another pigment, dye or the like with the resin component.

Such pigments include inorganic pigments such as calcium carbonate, barium sulfate, zinc oxide, titanium oxide, and yellow pigments in white. Chrome yellow, cadmium yellow, reddish iron oxide (Vengala), cadmium red (sulfide), molybdenum There are various types of yellow-red azo pigments, blue-green type, and organic types such as cobalt (oxide) and blue type. Phthalocyanine pigments, and quinacridone, perylene, isoindolinone, quinophthalone, etc. Illustrated as what can be used. In addition, various types of dyes are appropriately used.

The inner and outer members of the present invention as artificial stone molded products as described above can be manufactured, for example, by the following driving method.

<I> Implantation of artificial stone as a unit in which the light emitting part is dispersed in the base material

In this case, a predetermined mixture of the composition of the base material and the composition of the light emitting portion is put into a mold in a molten state, and compression molding or the like is possible.

This driving is realized by heating at a temperature of about 90 to 140 ° C during compression with a surface pressure of about 5 to 10 O kgf / cm ² , for example.

After the molding, surface roughening treatment and polishing are performed by using a one-night jet.

The method of compression molding by such driving shows a mass-production effect as a relatively simple molding method like a flat molded product, and the loss of material is reduced. It is economical because it has few.

The means for polishing the surface is not particularly limited, and a tool such as a grindstone, a polishing cloth, a polishing belt, or a buffing abrasive, a rubbing compound, or the like is used. It can be carried out using an abrasive.

Examples of abrasives include diamond, which mainly has an abrasive action, boron carbide, cation, aluminum, zirconia, and polishing. The main components are tripoli, dromite, aluminum, chromium oxide, and cerium oxide.

Then, in the present invention, the surface of the molded body after the molding may be subjected to a roughening process so that the fine particle component is exposed to the surface portion.

As a method for this, first, a method for selectively removing resin components is employed. That is, for example, it is effective to apply a high-pressure water to the surface of the molded article to remove the mold from the molding die, and to perform a surface treatment.

This processing is not limited because it varies depending on various conditions such as thickness, distance from a nozzle, processing form, and the like.

For a thickness of 2 to 20 cm, the height of the nozzle can be about ² to 50 cm, and the water pressure can be about 50 to 140 kg / cm2. . This pressure is lower than in the case of natural stones.

In other words, the presence of the resin makes it easier to perform high-quality processing.

There are no particular restrictions on nozzles and systems for jetting high-pressure water. Various things will be adopted.

By this ground surface processing, flattening or roughening is achieved by the WoW sunset, and an artificial stone with a deep texture is achieved. Be manufactured.

The surface does not become cloudy due to the presence of the resin component, and the disposal of the waste liquid becomes easier as compared with the etching method using chemicals.

Of course, the surface can be treated with an organic solvent if necessary. Alternatively, the resin component can be softened or melted and partially removed.

The organic solvent used in this case may be selected according to the resin component used. For example, halogenated carbonization such as ethylene chloride and chloroform may be used. Hydrogen, acetic anhydride, ethyl acetate, butyric acetate and other carboxylic acids and their ester compounds, or acetate, tetrahydrofuran, DMF, DMSO etc. are shown.

The molded body is immersed in these organic solvents, or the organic solvent is sprayed or flowed down, and the softened or melted resin component is exposed to the surface. By removing from the surface, surface irregularities can be formed.

Alternatively, irregularities may be formed by scraping the resin component having low hardness from the surface by a wire brush, cutting means, or the like. .

After the surface is roughened by the various means described above and the ground surface is processed, the surface is polished as described above, so that a unique depth and glossy surface texture can be obtained. Is achieved.

<I> Driving with projection as light emitting part

FIG. 1 is a diagram exemplifying an artificial stone molding (1) having a projection (3) as a light emitting portion.

That is, the substrate (2) has a projection (3) for a figure or pattern integrally on a plane portion thereof, and the base material is composed of an inorganic aggregate and a resin. At least part of (3) is a light emitting part (31) made of a phosphorescent material and a light emitting part (32) made of a fluorescent material.

Such artificial stones correspond to the projections (3) on the inner bottom surface. In the groove of the mold having the groove, at least a part of the inorganic aggregate is used as a phosphorescent material, a fluorescent material and a transparent inorganic aggregate, or the luminous or fluorescent substance described above. Inject the mixture containing the transparent inorganic aggregate baked on the surface, then inject into the mold the base material mixture containing the inorganic aggregate, press harden and demold. Then, if necessary, the surface may be polished or may be subjected to a surface roughening treatment by using a power jet or the like. In this way, an artificial stone molding (1) having a light-emitting portion only in the projection (3) is manufactured.

In curing with the upper mold together, compression is performed by pressing with a surface pressure of, for example, about 5 to 100 kgf / cm ² . In this molding, the material is heated at a temperature of about 90 to 140 for about 5 to 20 minutes during compression.

The mixture forming the light emitting part as the projection part (3) and the mixture forming the substrate part (2) are integrally formed by the above-described curing step by compression. . For this reason, the light emitting portion projection (3) does not peel off or fall off. In addition, the projection (3) is also formed as having excellent wear resistance due to its composition.

<Π> Artificial stone with embedded part as light emitting part

FIG. 2 is a diagram exemplifying an artificial stone (1) in which the embedding part (4) is used as a light emitting part.

That is, the substrate (2) has an embedded portion (4) for a figure or pattern integrally on a plane portion thereof, and the base material is made of an inorganic aggregate and a resin. At least a part of the buried part (4) has a luminous part made of a phosphorescent material and a fluorescent material embedded therein.

In this case, the inner bottom surface corresponds to the molded product embedding groove (4). The base material mixture containing the inorganic aggregate is injected into a mold having protrusions, and the mold is cured or semi-cured, and the mold is removed, and the grooves formed on the surface of the molded body are removed. A phosphorescent material or a fluorescent material as at least a part of the inorganic aggregate, or a transparent inorganic aggregate or a phosphorescent material or a fluorescent material as described above. A mixture (6) containing a transparent inorganic aggregate whose surface is baked on the surface is poured and hardened, and an artificial stone having a light-emitting portion only in the embedding portion (4) (1) is manufactured.

Also in this method, the hardening by compression molding can be performed in the same manner as in the above method, and the artificial stone (1) is finally appropriately polished similarly. Or roughened.

For example, in any of the above methods, when using a transparent inorganic aggregate whose surface is coated with a phosphorescent material or a fluorescent material, polishing or other treatment is required. Thus, the cross sections of the particles and the coating layer are exposed so that the particles are exposed.

This produces an artificial stone with excellent texture and texture, as well as excellent luminous properties.

In other words, for example, if the surface of the pongee particles is coated with a phosphorescent or fluorescent material by baking, the polishing of the surface of the artificial stone will cause the fine particles to become finer. And the coating is exposed as a cross section. In this way, the light emitted from the outside is incident from the exposed transparent fine particle surface, and reaches the baked coating material inside. .

In the case of highly transparent resin such as methacrylic resin, light transmission can be improved as a whole.

As a result, the incident light penetrates into the light emitting part, The part also emits light.

As a result, it is possible to store and absorb light in a short time, and the luminous efficiency is also increased.

The above example describes the case where the inner and outer members of the present invention are constituted by artificial stones. However, depending on the constitution of the phosphorescent material, the fluorescent material, and the base material, In addition, various modes are possible.

For example, it is exemplified as follows.

Example 1: Mortar or liquid mixture of various combinations of base material and phosphorescent material or fluorescent material are directly driven into a mold so as to have the shape as a product. Mold.

Example 2: For example, the substrate section (2) shown in Figs. 1 and 2 is made of resin, glass, ceramics, metal, etc., and the light emitting section is formed. (3) Driving or inserting (4).

The light-emitting portions (3) and (4) may be appropriately selected from a resin, a glass, and the like as a binder in consideration of adhesion to a base material.

Example 3: A semi-cured artificial stone base material, as well as a semi-cured resin, glass, etc., are coated with a phosphorescent or fluorescent material so as to form a predetermined figure or pattern. The combination of these and the binder is pushed in to integrate with the base material. In any of the embodiments, according to the present invention, the light emission by the light storage material under the visual field at night or the like, which has the color tone design at normal times, and the ultraviolet light irradiation (brightness) The interior and exterior materials that can emit light from the fluorescent material are also provided. O

These include various interior and exterior materials, such as floors, ceilings, walls, partitions, skirting boards, pillars, etc., or building materials such as housing equipment, furniture, etc. For example, doors, window frames, tables, countertops, handrails, stairs, etc., bathrooms, kitchens, toilets, etc., and blocks. It is useful as a building, a pillar, a wall, a road, a fence, a gate, etc., and also used as a welfare braille block.

In the above description, the phosphorescent material and the fluorescent material are used together. However, when viewed as a product, the light-emitting part as the phosphorescent material and It is needless to say that the light emitting part as the fluorescent material may be arranged at a different position. As a product, there is no difference between the two being driven or fitted together into the base material.

When the inner and outer materials of the present invention are constituted as artificial stone, glass, ceramics, etc., for example, antibacterial agents such as silver are combined with the antibacterial agent. Its usefulness as a product is of value, and its added value can be further increased by providing radio and electromagnetic shielding functions.
