Conventionally, in the houses and buildings, such as interior materials and exterior materials, furniture, bath, toilet, kitchen equipment, or fences, pillars, doors, and horizontal members, including wood and cement concrete, Metals, ceramics, resins, or composites thereof have been used in various specifications, and properties such as water resistance, heat resistance, weather resistance, and strength are fundamental, and design, design, and construction with emphasis on designability have been performed.

Moreover, in recent years, there is a tendency for emphasis on color tone in the use of such various materials, and interest in the relationship between color and light is increasing. In this situation, for example, the integration and complexation of building materials and lighting has been examined in various ways.

On the other hand, as an interest in color and light, attention has been paid to the fluorescent function of emitting light in response to photoluminescence and ultraviolet light as a function of light in a state where illumination is stopped.

However, conventionally, in the blackout situation at the time of disaster, from the viewpoint of disaster prevention to clarify the indication and instructions under the dark field, coating paint, paint having dispersed the photoluminescent material, or attaching a photoluminescent dispersion resin tape, etc. It is only what has been done, and there is not suggestion to utilize as interior and exterior materials such as house, building.

In particular, in the case of conventional means, paint and paint or tape are worn and peeled off on substrates such as glass, concrete, resin, and the like, resulting in inferior durability. There was a problem that it could not be used as a member of a house facility such as a member or a member such as a fence or a door.

Under such circumstances, the inventors of the present application have made studies on the use of internal and external snow materials that can be used in actual houses, buildings, public facilities, and the like, having a photoluminescent property and a fluorescent property.

It is assumed that the hue is controlled and the sun again.

[Brief Description of Drawings]

1 and 2 of the accompanying drawings are cross-sectional views illustrating the configuration of artificial stone as an embodiment of the present invention.

Best Mode for Carrying Out the Invention

The invention of the present application will be described in more detail below.

The internal and external snow materials aimed at the present invention basically have the following requirements.

<A> Using a fluorescent material together with a phosphorescent material.

<B> The photoluminescent material and the fluorescent material are embedded or embedded in a substrate in which color tone is controlled.

Herein, the above-described <A> will be described. In the present invention, a phosphorescent material that absorbs and accumulates light energy of illumination such as sunlight and a fluorescent lamp and emits light under night dark field and a fluorescent material that emits light by irradiation of ultraviolet rays. In order to utilize each of the light emitting functions of and as a change in color, it is essential to use a phosphorescent material and a fluorescent material integrally.

In this case, the phosphorescent material and the fluorescent material can be made of an inorganic material or an organic material. However, from the viewpoints of durability and abrasion resistance, optical properties of the photoluminescent material and the fluorescent material, its persistence, etc., it is usually preferable to use an inorganic material.

Examples of such inorganic materials include oxides such as strontium aluminate, rare earth-activated aluminum and strontium, complex oxides and other various oxides, sulfides such as zinc, barium and strontium, and activators thereof.

These phosphorescent materials and fluorescent materials are used as powders or aggregates, and as composite powders and aggregates made of resin, glass, cement and the like as binders. The photoluminescent material and the fluorescent material as such various forms are embedded or embedded in the substrate as described later.

Next, about a <B> base material, it is comprised by an inorganic material or an inorganic material and resin as a component.

Herein, the inorganic material is preferably at least one of natural stone, ceramics, cement, metal or glass. In resin, it is preferable that they are thermosetting resins, such as an acrylic resin, methacryl resin, an epoxy resin, unsaturated polyester resin, or a combination thereof.

The inorganic material itself serves as a substrate, aggregate, or binder, and the resin is also the same.

For example, cement, glass, and the like can be used not only as a binder, but also fragments and subdivisions can be used as aggregates. On the other hand, natural stone, ceramics, metal can be used as a base material itself or its subdivisions and fragments as aggregate.

As an aspect in relation to a base material in the specification of the embedding or insertion of a phosphorescent material or a fluorescent material, the following are illustrated, for example.

1) A phosphorescent material or a fluorescent material is embedded in the base material as a mixed component.

1-1) For example, a phosphorescent material or a fluorescent material such as a powdery or small block is mixed with a base material containing cement, glass, resin, etc. as a binder component, and formed into a plate-like body or block body having a predetermined shape.

At this time, ceramics such as natural stone, tiles, and granular and fine particles such as glass, slag, inorganic fibers, and the like can form the base material as an aggregate component. When using these aggregate components, when a resin is used as a binder, an artificial stone will be comprised.

1-2) In this embedding, the substrate formed in advance has a type portion such as a sphere, a hole, and the like, and a phosphorescent material or a fluorescent material is a binder, resin, glass, cement, etc. It is also realized by being embedded in the mixed state and cured.

1-3) Drive may be inverse to the above. That is, the photoluminescent material and the fluorescent material are formed in a predetermined shape together with a binder or the like, and the base component is embedded as a mortar mixture and cured so as to be integrated as a part of the whole product.

1-4) In the above 1-2) and 1-3), the building material constitutes a laminated material, and the layer of the photoluminescent material and the fluorescent material may be laminated and integrated on the surface of the substrate.

1-5) In said 1-2), 1-3), and 1-4), the molded object before injecting may not only be a hardened | cured material but a semi-hardened state.

2) In the present invention, a phosphorescent material and a fluorescent material are sandwiched in the substrate.

That is, the photoluminescent material and fluorescent material shape | molded in the predetermined shape with respect to the base material currently shape | molded are inserted and integrated. This insertion may form a laminate with a base material.

And this embedding is used in the present invention, and may be integrally bonded using a binder or an adhesive, or may be embedded by physical assembly.

In the internal and external snow materials of the present invention, in any of the above-described 1) embedding and 2) embedding, not only the color tone and the shape are adjusted in accordance with the use and purpose as a building material, but also the metal as the structure in the shape. It may be integrated with members peculiar to ceramics, resins and the like. These members may be projections and bolts, engagement hooks, reinforcing plates, mesh bodies, and other various materials. For example, it may be for the electromagnetic shield. It may be integrated with various members for construction and attachment as a building construction.

And in this invention, it is essential that the base material is controlled with a hue and predetermined thing. this is,

① Color under normal lighting such as sunlight and fluorescent lights

② Color of light emission by phosphorescent material under dark field such as night light

③ Color of light emitted by fluorescent material in conjunction with ultraviolet irradiation

It is to enable change of three phases of family.

About the color tone of the base material itself, it is realized by the color embodied in the base material itself, or further by adding and mixing an inorganic or organic pigment and dye with respect to the base material.

Hereinafter, in more detail, the case where an artificial stone is comprised is demonstrated as a preferable embodiment of the internal and external snow material of this invention.

Artificial stone inside and outside

As a composition of an artificial stone, it can be assumed that it contains the inorganic material and resin as an aggregate as a basic component, for example. In this case, examples of the inorganic material include a wide range of natural stones, natural minerals, artificially synthesized inorganic materials, glass, and metals.

As the light emitting portion, a fluorescent material is used together with the photoluminescent material as at least a part or all of the inorganic aggregate.

<Configuration of the base material integral with the light emitting part and the light emitting part>

Although the phosphorescent material and the fluorescent material contain resin in the light emitting part or the base material in which the light emitting part is dispersed and integrated, a transparent inorganic aggregate may be further blended. In the case where the transparent inorganic aggregate is contained, the weight ratio of both is set to 1: 2 to 1:10, and the sum of the two is set to be 80 to 95% by weight of the whole light emitting part composition.

In addition, the transparent inorganic aggregate having the surface-baked coating of the phosphorescent material and / or the fluorescent material may be contained, and in this case, it is good to make it 5 to 65 weight% of the total amount with respect to the composition weight of a light emitting part.

In view of physical properties such as peeling resistance, dropping resistance, and abrasion resistance, and luminescence performance, the above-mentioned formulation is good.

As an inorganic aggregate, what combined the following two types is illustrated as a good thing. That is, one is a mineral granule of 5 to 70 mesh size, which is a mineral fine granule selected from minerals such as quartz, olivine, feldspar, fluorite and mica, and natural stone such as granite and modified stone, ceramics, glass and metal. .

And the fine component of less than 100 mesh is used together with this fine grain component. As this fine grain component, the natural or artificial various fine grain components are recommended. For example, calcium carbonate, aluminum hydroxide, silica powder, etc. are easy to obtain particulate components.

In addition, as a part of this particulate component, components such as manganese dioxide, titanium dioxide, zirconium silicate, iron oxide, etc. are added to adjust the color tone, and components such as antimony trioxide, boron compound, bromine compound, etc. are added to impart flame retardancy / nonflammability. You may also

The fine grains function as a major factor in the appearance and physical properties of the resulting artificial molded article. The fine component is considerably thinner than the level of 100 meshes compared with the fine grain component, and it penetrates between the particles of each fine grain component, is located to fill the space between the particles, and contributes to obtaining the properties of the rigidity and softness of the artificial stone obtained. The fine grain component and the fine grain component are preferably 0.5: 1 to 5: 1 and more preferably 1: 1 to 4: 1 by weight. When constructing the artificial stone molded body by combining the fine grain component and the fine grain component, the configuration of the light emitting portion may be considered as follows.

That is, when using a photoluminescent material as a part of the inorganic aggregate, and a fluorescent material and a transparent inorganic aggregate, the transparent inorganic component is used as at least a part of the fine granules, and the photoluminescent material and the fluorescent material as at least part of the particulate component. It is good to use ash.

The fine grain component as a transparent inorganic aggregate means that it is an inorganic component having a large light transmittance substantially. Although there are various degrees of transparency, a relatively large light transmittance is used in the present invention for a natural or artificially synthesized inorganic material. do. For this reason, the transparent inorganic fine grain component may be a colored state or a state having an inherent color.

Typically, quartz stone, silica, glass and the like are exemplified in the present invention as transparent inorganic fine grain components, but are not limited thereto.

The artificial stone contains a phosphorescent material and a fluorescent material of less than 100 mesh as a part of the particulate component. Typical examples of such components include strontium aluminate-based photoluminescent materials, zinc sulfide, and the like. These various materials are used in the present invention.

The inorganic fine grain component imparting the role of artificial stone as aggregate is in the range of 5 to 70 mesh as described above, but this is an indispensable requirement in combination with the inorganic fine grain component. In addition, in the case of the photoluminescent material or the fluorescent material, not only the role of particulate matter is imparted but also the optical function is imparted to the artificial stone. The size of the phosphorescent material or the fluorescent material, like the particulate component, is less than 100 mesh is indispensable.

As mentioned above, the compounding ratio together with the size becomes an important requirement for each inorganic component.

That is, the relationship between the weight (W ₁ ) of the inorganic fine grain component, the weight (W ₂ ) of the inorganic fine particles, and the weight (W ₃ ) of the phosphorescent material or the fluorescent material component

W ₁ : (W ₂ + W ₃ ) = 0.5: 1 to 5: 1

W ₂ : W ₃ = 1: 2 to 10: 1

It is good to be.

W _1: a better than for the (W ₂ + W ₃₎ is 1: 1~4: 1 degree, and also, W _2: 1~5:: better than that of 11 W for _3.

As described above, with respect to the inorganic fine grain component, the ratio of the transparent inorganic fine grain component is

(0.5 to 1.0) W ₁

It is hopeful to be in a relationship.

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

In addition, the size of each component is appropriately selected depending on the size and blending ratio of each of the components to be specifically combined, but the fine particles, the phosphorescent material or the fluorescent material component is generally more preferably about 150 to 250 mesh.

When further explaining the optical function of the artificial stone, in the artificial stone of the present invention,

1) Containing 30 to 100% by weight of inorganic fine grain component as transparent inorganic fine grain component

2) blending components of phosphorescent material and fluorescent material with less than 100 mesh in specific ratio as above

By this means, it is realized as an artificial stone having an optical function of emitting light accompanied with luminescence or light emission with fluorescence. In this case, the feature becomes that the light emission is thick. Not only light emission in the surface layer portion, but light emission in the entire thickness of artificial stone as in the prior art, excellent light emission performance, and also excellent in the economics associated with the use of expensive luminous or fluorescent components.

This is due to the use of a transparent inorganic fine grain component as a transparent aggregate, sunlight and externally irradiated light penetrates into the interior of the artificial stone, and its light energy is efficiently absorbed by the luminous or fluorescent material components, and the phosphorescent material This is because it is possible to maintain high brightness for a long time because the light emitting layer in which the back is dispersed is secured to a large thickness including the inside of the artificial stone. This is because the transparent inorganic fine grain component at the time of light emission has high light transmittance due to good light transmittance.

Although the ratio of the transparency component which occupies the whole fine grain component is 30 to 100 weight% as mentioned above, it is natural that it is good from a viewpoint of an optical function to make it the ratio of 100% by physical property, such as artificial stone strength, and external appearance. Of course, it is not limited to this, but less than 30% of the required optical function is difficult to obtain.

In the case of using a transparent inorganic aggregate surface-baked by a phosphorescent material and / or a fluorescent material as part of the inorganic aggregate, as the fine-grained component, in the present invention, at least a portion of the inorganic aggregate is transparent and the phosphorescent material and the ultraviolet ray on the surface thereof. It can be used by baking the fluorescent material with luminescence accompanying absorption. That is, part or all of the fine grain component is a transparent inorganic aggregate in which the phosphorescent material and / or the fluorescent material is coated on the surface thereof. Such fine grains as transparent inorganic aggregates are exemplified by glass and silica.

About the fine grain component mix | blended with a composition, it is good to set the 10-100% ratio (weight) as transparent inorganic aggregate which has the surface coating layer of the said photoluminescent material and / or fluorescent material.

In the coating of the transparent inorganic aggregate, in particular the fine grain component, the surface of the particle of the transparent fine grain component is coated with several micrometers to several tens of micrometers, for example, 5 to 50 micrometers, preferably 20 to 40 micrometers. More specifically, baking can be performed by baking at a high temperature of about 120 to 1200 ° C.

As the photoluminescent material and the fluorescent material to be baked, various materials such as strontium aluminate and zinc sulfide may be used.

In addition to various methods known in the art, baking may be carried out by dispersing powder particles of a photoluminescent material such as strontium aluminate, and mixing a transparent inorganic aggregate such as the fine grain component in a dispersion or paste, followed by drying and baking.

Moreover, as mentioned above, it is preferable that the magnitude | size of an inorganic fine grain component shall also be specified. In other words, the inorganic fine grain component is 5 to 70 mesh in size as described above. It is considered to change the size of the fine grains with or without color when using a non-colored one to make the color darker on the top or the bottom. Should not be used as it will degrade the temperature.

On the other hand, the particle size of the particulate component is to be less than 100 mesh as described above. There should be enough space between the fine grain particles. More specifically, about 150-250 mesh is preferable.

In addition, the resin component can be selected from a wide range of thermosetting ones.

For example, acrylic resin, methacryl resin, epoxy resin, unsaturated polyester resin, a combination thereof, etc. are illustrated. These may be homopolymers or copolymers. Among them, methacryl resin, epoxy resin or a combination thereof is exemplified in terms of transparency, hardness and strength. The blending ratio of the resin component is preferably less than 15% by weight, more preferably 10% by weight or less of the entire composition. This resin component contributes to joining the whole of the fine-grained and fine-grained components, which form the above-mentioned skeleton, by binding them, and providing elasticity or tensile strength to the product when the artificial stone is completed. The usage-amount ratio of the inorganic aggregate which consists of a fine grain component and a fine component is limited. That is, it must be 85% or more by weight ratio, Preferably it is 89% or more. Moreover, if it exceeds 95%, the product becomes vulnerable and only hard to use is obtained. In addition, if it is less than 89%, the product is too flexible and no stone-like property is obtained, and the range of use is the same as that of the resin plate.

This means that other than fine grains and fine grains such as natural stone, that is, the resin component should not exist more than 15% by weight even in the product.

If the resin content exceeds 15%, the product becomes like plastic and is already named only artificial stone. In addition, too small a resin component may increase the appearance of the product near its natural color, but the product becomes vulnerable and unsuitable for use. More preferably, from this viewpoint, the resin component is 5 to 11% by weight.

As the artificial stone, the usual color of the internal and external snow materials of the present invention is adjusted according to the kind of the inorganic aggregate to be blended, its particle diameter and the compounding amount, as shown from the above, but on the other hand, the resin component, as well as other pigments and dyes, It is also adjusted by blending.

Such pigments are inorganic, white, for example calcium carbonate, barium sulfate, zinc sulfide, titanium oxide, yellow chromium yellow, cadmium yellow, red iron oxide (bengara), cadmium red (sulfide), molybdenum Red (oxide) and cobalt blue (oxide) are mentioned as a blue type | system | group, As an organic type, various yellow-red azo pigments, blue-green phthalocyanine type pigments, Furthermore, quinacridone type, perylene type, isoindolinone type It is illustrated that a quinophthalone system etc. can be used suitably.

Moreover, various kinds of dyes are suitably used.

<Configuration of Base Material Different from Light Emitting Part>

In the case of artificial stone, it is possible to have almost the composition of the above resin and inorganic material.

For example, the base material is roughly divided into three components. One of the main components is mineral granules of 10 to 70 mesh size, which are minerals such as silica, olivine, feldspar, fluorite, mica, and natural granules such as granite, metamorphic rock, ceramics, glass, and metal. .

In addition, an inorganic fine grain component of less than 100 mesh is used together with this fine grain component. As this particulate component, various particulate components which are natural or artificial are enumerated. For example, calcium carbonate and aluminum hydroxide are easy to obtain particulate components.

As a part of this particulate component, components such as manganese dioxide, titanium dioxide, zirconium silicate, iron oxide, etc., for adjusting color tone, and components such as antimony trioxide, boron compound, bromine compound, etc. for imparting flame retardancy may be added and mixed.

The third component is a resin component. The resin component can be widely selected from thermosetting ones.

For example, acrylic resin, methacryl resin, epoxy resin, unsaturated polyester resin, etc. which were mentioned above are illustrated. Among them, methacryl resin and epoxy resin are suitable in terms of transparency, hardness and strength.

Fine-grained components, such as natural stone, function as a major factor in the appearance and physical properties of the artificial stone obtained. In particular, by exposing a part, it becomes the main cause of appearance color and shape by matching with other components.

The fine component is considerably thinner than the level of 100 meshes compared with the fine grain component, and is located to fill the space between the particles by infiltrating between the individual fine grain components, thereby contributing to obtaining the properties of rigidity and softness of the artificial stone obtained. The fine grain component and the fine grain component are preferably 0.5: 1 to 5: 1 in weight ratio.

In addition, the resin component contributes to joining the entirety of the fine-grained components, such as natural stone, which is a component that forms the skeleton, and the fine-grained components, surrounding them, and imparting elasticity or tensile strength to the product when the artificial stone is completed. There is this.

In the present invention, the composition ratio of these components is important. Especially important is the composition ratio of a resin component and another component. In the present invention, it is also one of the features to enable a high-density product having a dense structure, wherein high density means that the fine and fine components contained in the artificial stone products are present at a high density, for example, density 2.2 It says g / cm <3> or more, and is beyond the range contained in the conventional artificial stone.

That is, although the composition ratio in the product of fine-grained components, such as a natural stone which is a skeletal component, is large, it becomes close to natural stone, but when too many, it becomes hard and cannot be used as a product. In addition, the physical properties of the product obtained are poor, so that the use according to the usual usage is difficult.

In addition, irrationality such as not being hardened even when a large amount of the particulate component is used is generated, and it is difficult to say that the obtained product is free of color salts.

Therefore, the usage-amount ratio of a fine grain component and a fine grain component is limited. That is, it should be 85% or more by weight ratio, preferably 90% or more. Moreover, if it exceeds 95%, the product becomes weak and difficult to use. In addition, if it is less than 85%, the product is so flexible that stone-like properties are not obtained, and the range of use is the same as that of the resin plate.

This is other than fine grains and fine grains such as natural stone, that is, the resin component should not exist more than 15% by weight even in the product.

If the resin content exceeds 15%, the product becomes like plastic, and it is already named only artificial stone. In addition, too small a resin component may increase the appearance of the product near its natural color, but the product becomes vulnerable and unsuitable for use. More preferably from this viewpoint, the resin component is 3 to 10% by weight.

In the artificial stone composition and the artificial stone as the product of the present invention, some or all of the inorganic fine grain components may be transparent particles, and the particles or small lumps may be coated with an inorganic or organic substance in advance.

This coating of the transparent fine grain component coats and cures the resin on the surface of the transparent fine grain component, or burns inorganic materials such as glazes, phosphorescent materials and ultraviolet absorbing fluorescent materials for water glass and ceramics. By coating). In either case, the surface of the particles of the transparent fine grain component is coated with a thickness of several micrometers to several tens of micrometers, for example, 5 to 50 micrometers, preferably 20 to 30 micrometers. More specifically, for example, an acrylic resin, a methacryl resin, an epoxy resin, an unsaturated polyester resin composition may be heated to about 150 to 300 ° C., or light irradiated to coat and harden these resin compositions on the surface of the fine particles. The inorganic coating may be performed by baking at a temperature of about 800 to 1100 ° C. using water glass, glaze, or the like.

These coatings greatly improve the affinity for the whole tissue of the fine grain component which functions as an artificial stone aggregate. Moreover, the strength is large and the surface hardness is also improved by mixing the particulate component and the resin component.

As the fine-grained component is made of transparent natural stone or the like as described above, and the hard coating is applied to the surface thereof, when the surface of the artificial stone product is polished, the coating layer is partially peeled off. Then, the surface texture of the partially exposed inorganic transparent fine grain particles and the coating layer around them obtains a unique effect by the reflection of light.

That is, light enters the transparent fine grain component, is reflected by the surrounding coating layer, and is reflected by retransmitting the transparent fine grain component. The phenomenon of light transmission and reflection is essentially different from the reflection of only the surface of the conventional artificial stone, and gives a unique sense of depth to the artificial stone product of the present invention. You get a deep, high-quality marble artificial stone with a heavy depth. As mentioned above, the transparent fine grain component which has a coating layer can be made into the ratio of 10 to 100% generally as whole quantity of the inorganic fine grain component mix | blended with a composition.

In addition, in this invention, the magnitude | size of an inorganic fine grain component also needs to be made specific. That is, the inorganic fine grain component is 10-70 mesh in size as mentioned above. It is considered to change the size of the fine grain with or without the color when you want to make the color darker on the top or the bottom using the one with or without the color, but the mass use of the thing with the extreme difference is the strength of the product Should not be used as it will degrade the temperature.

On the other hand, the size of the particulate component is to be less than 100 mesh as described above. It must be put enough between the particles of a fine grain component. More specifically, about 150-250 mesh is preferable.

In addition, it is desired that these material compositions are uniformly dispersed in any part of the product, except for the special case, which is important for the high density artificial stone in the embodiment of the present invention.

As the artificial stone, the usual color of the internal and external snow materials of the present invention is adjusted according to the kind of the inorganic aggregate to be blended, its particle diameter and the compounding amount, as shown from the above, but on the other hand, the resin component, as well as other pigments and dyes, It is also adjusted by blending.

Such pigments are inorganic, white, for example calcium carbonate, barium sulfate, zinc sulfide, titanium oxide, yellow chromium yellow, cadmium yellow, red iron oxide (bengara), cadmium red (sulfide), molybdenum Red (oxide) and cobalt blue (oxide) are mentioned as a blue type | system | group, As an organic type, various yellow-red azo pigments, blue-green phthalocyanine type pigments, Furthermore, quinacridone type, perylene type, isoindolinone type It is illustrated that a quinophthalone system etc. can be used suitably.

Moreover, various things are suitably used from many dyes.

<Embedded>

The internal and external snow materials of the present invention as the artificial stone molded article as described above can be produced, for example, by the following embedding method.

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

In this case, a predetermined mixture mixture of the substrate composition and the light emitting portion composition is introduced into the mold in a mortar state, and is made possible by compression molding or the like.

This embedding is realized by heating to a temperature of about 90 to 140 ° C. at the time of compression with a surface pressure of, for example, about 5 to 100 kgf / cm 2.

After molding, surface roughening and polishing are performed with a water jet.

The compression molding method incorporating such a molding has a mass production effect by a molding method having a relatively simple shape such as a flat molded article, and is excellent in economical efficiency since there is almost no waste of material.

The means for surface polishing is not particularly limited, and may be carried out using tools such as grindstones, abrasive cloths, polishing belts, or abrasives such as buff polishing agents and lapping compounds. have.

As the abrasive, diamond, boron carbide, korandam, alumina, zirconia and tripoly, mainly dolomite, alumina, chromium oxide, and cerium oxide, which are mainly used for polishing, are appropriately used.

And in this invention, you may roughen a surface of the molded object after shaping | molding, and let a particulate component expose to a surface part.

As a method for this, first, a selective removal method of the resin component is adopted. That is, for example, it is effective to perform surface treatment by blowing high pressure water onto the surface of the molded product after demolding from the molding die.

This processing is not limited because it depends on various conditions such as thickness, distance from the nozzle, and processing type. However, in the case of 2 to 20 cm thickness, it is usually 50 to 1400 kg / cm 2 at the nozzle height of about 2 to 50 cm. I can do it with precision water pressure. This pressure is a lower hydraulic pressure condition than natural stones.

That is, it is because the process to high quality can be carried out easily by presence of resin powder.

There is no particular limitation on the nozzle and the system for ejecting high pressure water. Various things are adopted.

This ground surface processing realizes flattening or roughening with a water jet to produce an artificial stone having a deep texture.

Due to the presence of the resin component, the surface is not cloudy and the waste liquid can be easily processed as compared with the etching method using chemicals.

Of course, if necessary, the surface portion may be treated with an organic solvent, and the resin component may be softened or melted to partially remove it.

In this case, the organic solvent may be selected according to the resin component to be used. For example, halogenated hydrocarbons such as ethylene chloride and chloroform, carboxylic acids such as acetic anhydride, ethyl acetate and butyl acetate, and ester compounds thereof such as acetone and tetrahydro. Furan, DMF, DMSO, etc. are illustrated.

The molded product can form surface irregularities by depositing on the organic solvent or spraying or flowing these organic solvents to remove the softened or molten resin component from the surface portion.

In addition, unevenness may be formed by cutting the resin component having low hardness from the surface portion by a wire brush, cutting means or the like.

After surface roughening by the above various means and ground-surface processing, the surface is polished as mentioned above, and the surface texture with a unique depth and beauty is realized.

<II> Injecting projection into light emitting part

1 is a diagram illustrating an artificial stone molded body 1 having the protrusion 3 as a light emitting part.

That is, the projection part 3 for a figure or a shape is integrated in the planar part of the board | substrate 2, a base material becomes an inorganic aggregate and resin, and at least one part of the projection part 3 is light-emitting part 31 by a photoluminescent material. And the light emitting portion 32 by the fluorescent material.

Such artificial stone has a phosphorescent material and a fluorescent material and a transparent inorganic aggregate, or a luminous or fluorescent material, as the at least part of the inorganic aggregate, formed on the surface of the molded die having the bend corresponding to the protrusion 3 on the inner bottom. The mixture containing the prepared transparent inorganic aggregate is injected, and then the base mixture containing the inorganic aggregate is injected into the molding die and cured by pressing and demolding, and then roughened by grinding or water jet as necessary. . Thereby, the artificial stone molded body 1 which has a light emitting part in only the said projection part 3 is manufactured.

In order to cure | harden the upper mold | type 8, it compresses by pressing by surface pressure of about 5-100 kgf / cm <2>, for example. In this molded object, it is heated for about 5 to 20 minutes at a temperature of approximately 90 to 140 ° C during compression.

The mixture forming the light emitting portion as the projection portion 3 and the mixture forming the substrate portion 2 are integrally formed in the curing step by compression. For this reason, there is no peeling or falling off of the light emitting part projection part 3. Moreover, the projection part 3 is also formed by what is excellent in abrasion resistance by the composition.

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

2 is a diagram illustrating an artificial stone 1 having the buried portion 4 as a light emitting portion.

That is, the embedding part 4 for figures or shapes is integrally formed in the planar part of the board | substrate 2, and a base material becomes an inorganic aggregate and resin, and at least a part of the said embedding part 4 is used as a phosphorescent material and a fluorescent material. The light emitting portion to be embedded is embedded.

In this case, the base mixture containing the inorganic aggregate is injected into the mold having the protrusion corresponding to the molded body inlet 4 on the inner bottom, cured or semi-cured, and demolded. At least partly containing the phosphorescent material and the fluorescent material or moreover the transparent inorganic aggregate, or the mixture 6 containing the transparent inorganic aggregate in which the phosphorescent material or the fluorescent material is baked on the surface is cured by injecting and curing only the buried portion 4 An artificial stone 1 having a light emitting portion is manufactured.

Also in this case, the hardening by compression molding can be carried out in the same manner as in the above method, and the artificial stone 1 is finally polished or roughened in an appropriate manner.

For example, in any of the above methods, when using a transparent inorganic aggregate surface-coated with a photoluminescent material or a fluorescent material, the cross section of the particles and the coating layer is exposed by processing such as polishing.

By doing so, an artificial stone having excellent luminescence and excellent surface matching and texture is produced.

That is, for example, if the photoluminescent material or the fluorescent material is baked on the surface of the fine grain component, the fine grain component particles and their coating are exposed as cross sections by surface polishing of artificial stone. In this way, the light irradiated from the outside is incident on the surface of the exposed transparent fine particles to reach the baked coating material inside.

In the case of the highly transparent methacryl resin etc., the permeation | transmission of light is made favorable as a whole.

For this reason, incident light penetrates inside the light emitting portion and emits light even inside.

For this reason, light absorption and photoluminescence of a short time are attained, and luminous efficiency becomes large.

The above example has been described in the case of configuring the interior and exterior snow material of the present invention by artificial stone, but more various forms are possible depending on the configuration of the photoluminescent material, the fluorescent material, and the substrate.

For example, it is illustrated as follows.

Example 1: A mortar or liquid mixture of various combinations of a base material, a photoluminescent material, and a fluorescent material is molded into a mold so as to form a direct product.

Example 2: For example, the board | substrate part 2 shown in FIG. 1 and FIG. 2 is comprised by resin, glass, ceramics, a metal, etc., and the light emitting part 3 (4) is embedded or inserted.

The light emitting portions 3 and 4 may be appropriately selected from resins, glass, etc. in consideration of adhesion to the substrate as a binder.

Example 3: A photoluminescent material and a fluorescent material or a combination of these and binders are pushed into the substrate to form a predetermined figure and shape in the semi-cured artificial stone substrate as well as the semi-cured resin and glass.

In any form, the internal and external snow materials having the usual color tone design according to the present invention and capable of emitting light by a fluorescent material in combination with light emission by a phosphorescent material and ultraviolet irradiation (black light) under a dark field such as night time Is provided.

These are various interior and exterior materials, such as floors, ceilings, walls, partitions, planks and lights (door frames), columns, or building materials such as housing, furniture, for example doors, window frames, tables, counter tops. ), Handrails, stairs, and bathrooms, kitchens, toilets, etc., as well as blocks, columns, walls, roads, fences, doors, etc., and also useful as a braille block for welfare.

In addition, although the above description demonstrated that the phosphorescent material and the fluorescent material are used together, it goes without saying that the light emitting portion as the phosphorescent material and the light emitting portion as the fluorescent material may be disposed at different positions when viewed as a product. This is because, as a product, there is no difference between being embedded or embedded in the substrate together.

When the internal and external snow materials of the present invention are made of artificial stone, glass, ceramics, etc., for example, by combining antimicrobial agents such as silver, their usefulness as an antimicrobial product becomes valuable, and has a radio wave and electromagnetic shield function to add value. Becomes higher.
