Description

Block structure having eco-friendly function

The present invention relates to a block structure, and more particularly to a block structure attached to the functional particles having an environmentally friendly function.

Recently, as environmental issues have emerged as important issues, interest in eco-friendly products to solve them has increased. In particular, the use of functional particles with environmentally friendly functions in building materials, for example blocks (here bricks used in buildings), sidewalk blocks and tiles, provides antibacterial, sterilization and deodorization functions, as well as anion release and The technology that can give the function of pollution resistance at the same time is developing. Functional particles having such environmentally friendly functions include photocatalyst, silver nano, gold powder and thermal barrier particles.

On the other hand, the method of applying environmentally friendly functional particles such as photocatalyst and silver nanoparticles to the block structure is a method of adding or applying the functional particles to the block structure. Through this, the functional particles are exposed to the outside of the block structure to remove contaminants encountered in the external environment. Here, the method of adding is mixing the block structure and the functional particles, and the method of applying is mixing the functional particles with a binder such as a binder to coat the surface of the block structure.

However, when the functional particles are mixed with the block structure or the binder, most of the functional particles are embedded in the block structure and the binder. As a result, there are too many particles that do not function properly in an eco-friendly manner. Specifically, when the block structure is used, the functional particles are relatively small so that the functional particles penetrate into the block structure and are not exposed to the outside of the block structure. In addition, in the case of application, the binder covers the exposed particles to the outside and its function is limited. As described above, according to the conventional method of adding or applying the functional particles to the block structure, there is a problem in that the functions of the functional particles cannot be properly exhibited.

 Therefore, the technical problem to be achieved by the present invention is to provide a block structure having an eco-friendly function that can be attached so that the functional particles are exposed to the outside to properly exhibit the function.

The block structure of the present invention for achieving the above technical problem is a porous ceramic carrier, functional particles supported on the ceramic carrier, having an environmentally friendly function, a skin layer to which the ceramic carrier is attached, and a substrate having the skin layer attached thereto. Include. At this time, the carrier may be partially embedded in the inside of the epidermal layer and the rest may be exposed on the surface of the epidermal layer.

In the present invention, the functional particles may be at least one of a photocatalyst or silver nano, and the skin layer may be any one of a mortar layer, a glaze layer, a glass plate, and a low temperature spray layer. In addition, the substrate is preferably at least one of bricks, sidewalk blocks, glass materials and tiles.

According to the block structure having the eco-friendly function of the present invention, by forming a skin layer to which the functional particles supported on the carrier are attached, it is possible to provide a block structure capable of exhibiting various functions according to the particles having the eco-friendly function.

1 is a cross-sectional view showing a block structure having a skin layer to which particles having an environmentally friendly function of the present invention are attached.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments described below may be modified in various forms, and the scope of the present invention is not limited to the embodiments described below. Embodiments of the present invention are provided to more fully explain the present invention to those skilled in the art.

In the embodiment of the present invention will propose a block structure in which the functional particles having an environmentally friendly function supported on the porous carrier is attached to the surface. Here, the block structure refers to a sidewalk block installed in the human side India, bricks and tiles used as interior and exterior materials of the building. The functional particles supported on the porous carrier applied to the present invention may be variously applied. In the present invention, the application is limited to bricks and tiles used as interior blocks of sidewalk blocks and buildings. This is because the problem that the existing block structure cannot solve is solved by the present invention.

Particles having eco-friendly functions (hereinafter referred to as functional particles) include photocatalysts, silver nanoparticles, gold powders and thermal barrier particles, and have air purification, antibacterial, sterilization and deodorization functions. Therefore, if the functional particles are attached to the outside of the block structure to be exposed to the outside, it is possible to manufacture a block structure that can properly exhibit the eco-friendly function.

Hereinafter, a block structure having a skin layer having functional particles adhered to the surface will be described in detail with some examples. Specifically, the examples will be divided and described based on the method of forming the skin layer.

<First Embodiment>

1 is a cross-sectional view showing a block structure having a skin layer to which functional particles having eco-friendly functions are attached according to an embodiment of the present invention. Referring to FIG. 1, the block structure of the present invention includes a substrate 10, a skin layer 20 on the substrate 10, a carrier 30 attached to the skin layer 20, and functional particles 40 supported on the carrier 30. ). The functional particles 40 are supported on the carrier 30 by an ion exchange method or a wet method. As shown, a portion of the carrier 30 carrying the functional particles 40 may be buried in the epidermal layer 20, and some may be exposed out of the epidermal layer 20.

In the embodiment of the present invention, the carrier 30 is preferably made of a ceramic material such as zeolite, silica, alumina, zirconium phosphate, or the like, and a porous metal may be used in some cases. That is, the carrier 30 may be a well-known porous material, and may carry the functional particles 40 in the pupil of the carrier 30. Since these functional particles 30 are only inherent in the pores of the carrier 20, when immersed in the solution, some of them may come out of the solution under certain conditions.

Functional particles 40 having an environmentally friendly function may include photocatalyst, silver nano, gold powder, thermal barrier particles, and the like. Among them, photocatalysts include TiO 2 , V 2 O 5 , ZnO, WO 3, and the like as catalysts that proceed with the catalytic reaction using light as an energy source. In particular, titanium oxide (TiO 2 ) is a high quality material excellent in whiteness and colorability, and can be used semi-permanently. In addition, since the oxidizing power is higher than that of chlorine (Cl 2 ) or ozone (O 3 ), it has a strong sterilizing power and a function of decomposing pollutants by organic substances, and can perform air purification, antibacterial, and deodorization. Therefore, photocatalysts are conventionally used in wall materials, tiles, glasses, circulating filtration apparatuses and sanitary ware.

In addition, silver nano is a nano-sized silver (Ag) particle, which is a material capable of fully exhibiting the properties of silver itself by increasing the surface area capable of reacting with other materials by using silver as fine particles. These silver nanoparticles are very effective in antibacterial, antiseptic, antifungal, etc., and are applied in many fields such as plating, paint, bimetal, deposition, dental materials, tableware, and the like.

Among the various functional particles having eco-friendly functions, titanium oxide and silver nano are used in various fields because of their excellent functions. In the embodiment of the present invention, various functional particles having an environmentally friendly function may be used, but it is particularly preferable to use the titanium oxide photocatalyst and silver nano.

The first embodiment of the present invention provides a method of forming the skin layer 20 to which the functional particles 40 are attached using mortar on a block structure such as a sidewalk block or a brick installed in a human sidewalk. Accordingly, in the first embodiment, the substrate 10 is preferably a brick or sidewalk block, and the skin layer 20 is a mortar layer formed of mortar. Here, with reference to FIG. 1 for the basic structure of the block structure in which the epidermal layer to which the functional particles are attached is formed.

Mortar is produced by kneading cement and sand with water, and is composed of lime mortar, asphalt mortar, resin mortar, vermiculite mortar, and pearlite mortar, depending on the type of fastener. This mortar has a physical property that gradually hardens with time, and is a porous material.

Therefore, in the case of producing the sidewalk block by directly adding functional particles such as titanium oxide to the mortar as in the conventional method, most of the fine titanium oxide powder is absorbed into the pores of the porous mortar. That is, most of the titanium oxide is buried in the mortar and the amount exposed to the surface is very small. Therefore, not only the titanium oxide function cannot be properly exhibited, but also a large amount of titanium oxide is required.

In contrast, in the first embodiment of the present invention, the skin layer 20 is formed by applying a mortar to a predetermined thickness on the surface of the substrate 10 already manufactured. Then, the carrier 30 on which the functional particles 40 such as titanium oxide are supported is attached on the skin layer 20. In this case, the carrier 30 on which the functional particles 40 are supported may be sprayed and attached by an injector (not shown), and the carrier 10 on which the functional particles 40 are supported may be added to the mortar to support the substrate 10. It can also be attached directly on the surface of the. Particularly, when the substrate 10 is a sidewalk block, the functional particles 40 are preferably titanium oxide having a photocatalytic function, and in the case of a brick of a building, at least one of titanium oxide having a photocatalytic function and silver nanoparticles having an antibacterial function. Would be preferred.

When the carrier 30 is attached to the mortar layer which is the epidermal layer 20 by the injector, the carrier 30 attached to the mortar layer bonds with the mortar layer by the hardening action of the mortar which hardens over time. Here, since the carrier 30 is a ceramic material such as zeolite, silica, alumina, zirconium phosphate, bonding with the mortar is very easy.

When the carrier 30 on which the functional particles 40 are supported is formed on the epidermal layer 20 made of mortar, the size of the carrier 30 is provided because the functional particles 40, which are fine powders, are supported on the carrier 30. As a result, the amount of the functional particles 40 absorbed into the pupil of the mortar is reduced. That is, compared with the conventional case of manufacturing the sidewalk block by directly adding the functional particles 40 to the mortar, the amount of the functional particles 40 absorbed into the pores of the mortar can be significantly reduced.

According to the first embodiment of the present invention, when manufacturing a sidewall block having a photocatalytic function, by attaching a carrier 30 carrying titanium oxide as a functional particle 40 to the skin layer 20 of the sidewalk block which is the substrate 10. Large amounts of titanium oxide can be exposed to the outside. As a result, the function of titanium oxide can be fully exhibited. In addition, since titanium oxide is supported in the carrier 30, the amount of titanium oxide absorbed into the mortar can be reduced. In addition, since titanium oxide is attached only to the skin layer 20 of the sidewalk block, which is the substrate 10, the sidewalk block may be manufactured using a smaller amount of titanium oxide than in the prior art.

Although only the substrate 10 is flat in the drawings in the first embodiment of the present invention, it is applicable within the scope of the present invention to bend or all possible forms depending on the use of the substrate 10.

Second Embodiment

In a second embodiment of the present invention, a method of forming a skin layer 20 having functional particles attached thereto using a glaze on a tile, which is a substrate 10 used as an interior and exterior material of a building, is provided. In other words, in the second embodiment, the substrate 10 is a tile, and the skin layer 20 is a glaze layer. Here, with reference to FIG. 1, the basic structure of the block structure in which the skin layer 20 to which the carrier 30 on which the functional particles 40 are supported are attached is formed is formed. Accordingly, since the same reference numerals as the first embodiment have the same function, detailed description thereof will be omitted herein.

Tiles are flat clay plastic products made to cover the surface of floors and walls, and include interior tiles, exterior tiles, mosaic tiles, and floor tiles. Such a tile product is simple to construct and hardly causes cracking or discoloration after construction, and is particularly durable, so it is widely used in kitchens, toilets, bathrooms, washrooms, and the like.

In general, when looking at the process for producing a tile, first, the fine powder is mixed and ground into a powder, such as silica, feldspar, pottery stone, and then kneaded with water to form. Thereafter, primary firing is performed, the glaze is applied, and then secondary firing is produced. Here, glaze refers to glassy lye used to coat porcelain surfaces.

In the second embodiment of the present invention can be applied to the glaze layer, which is the skin layer 20 formed through the process of applying a glaze on the tile in the process of manufacturing the tile, which is the substrate 10. That is, after performing the primary baking of the tile, which is the base material 10, applying glaze to form the skin layer 20, the carrier 30 carrying the functional particles 40 is coated on the skin layer 20 by coating it. As another method, the glaze to which the carrier 30 carrying the functional particles 40 are added may be directly coated on the tile, which is the substrate 10 on which the baking is carried out. Since the glaze is a glass material, it is easy to bond with the carrier 30 which is ceramic, and the carrier attached to the skin layer 20 is combined with the skin layer 20 through secondary firing, which is main roasting. As a result, the skin layer 20 having the functional particles attached to the tile may be formed.

In the second embodiment of the present invention, by attaching the carrier 30 carrying the functional particles 40 only to the glaze layer of the tile, a large amount of the functional particles 40 can be exposed to the outside to properly exert its function. . In addition, since the photocatalyst and the functional particles 40 such as silver nano are supported on the ceramic carrier 30, the amount of the functional particles embedded in the glaze can be reduced as compared with the conventional case in which the functional particles are directly added to the glaze.

In the second embodiment of the present invention, the tiles are only flat, but can be applied to the curved or all possible forms according to the use of the tiles within the scope of the present invention.

Third Embodiment

The third embodiment of the present invention proposes a method of forming a skin layer by bonding a thin glass plate on which a carrier 30 on which functional particles 40 are supported is adhered on a block structure such as a tile. In other words, in the third embodiment, the substrate 10 is any one selected from bricks, sidewalk blocks, glass materials, and tiles, and the skin layer 20 is a glass plate. Here, with reference to FIG. 1, the basic structure of the block structure in which the skin layer 20 to which the carrier 30 on which the functional particles 40 are supported are attached is formed is formed. Accordingly, since the same reference numerals as the first embodiment have the same function, detailed description thereof will be omitted herein.

Glass does not show a constant melting point when temperature is applied, but has a property of being converted into a liquid state with decreasing viscosity. Therefore, when heat is applied to the glass, the part where the heat contacts gradually decreases in viscosity and becomes soft. When the carrier 30 on which the functional particles 40 are loaded is sprayed on the glass plate converted into the liquid state, the carrier 40 penetrates into the surface of the flexible glass plate and adheres to the glass plate. The carrier thus attached is bonded to the glass plate by heat. Since the carrier is made of a ceramic material such as zeolite, silica, alumina and zirconium phosphate, it is easily bonded by heat with the glass plate which is the same ceramic material.

By bonding the glass plate, which is the skin layer 20 thus produced, onto the substrate 10, the skin layer 20 on which the functional particles 40 are exposed can be formed on the substrate 10. At this time, since the glass plate on which the carrier 40 on which the functional particles 40 are supported is adhered on the substrate 10 through an adhesive or the like, a printed material having a pattern is sandwiched between the substrate 10 and the glass plate for decoration. Can also be used.

According to the third embodiment of the present invention, by bonding the glass plate, which is the skin layer 20 with the carrier 30 on which the functional particles 40 are supported, onto the substrate 10, the functional particles 40 are formed on the substrate 10. May form an exposed skin layer 20. As a result, a large amount of functional particles can be exposed to the outside to properly exhibit its function.

<Fourth Embodiment>

In the fourth embodiment of the present invention, a method of forming the epidermal layer 20 having the carrier 30 on which the functional particles 40 are supported by the low temperature spray coating is provided. In other words, in the fourth embodiment, the substrate 10 is any one selected from bricks, sidewalk blocks, glass materials, and tiles, and the skin layer 20 is a low temperature spray layer. Here, with reference to FIG. 1, the basic structure of the block structure in which the skin layer 20 to which the carrier 30 on which the functional particles 40 are supported are attached is formed is formed. Accordingly, since the same reference numerals as the first embodiment have the same function, detailed description thereof will be omitted herein.

Low temperature spray coating is a technique that is coated while being adhered by the energy generated when a powder collides with a coating object by using a supersonic gas stream generated by compression and expansion. Therefore, unlike the conventional method of heating and coating the coating powder can be coated at room temperature to prevent deformation, deterioration of the material. In particular, it can be used for materials that are difficult to apply the existing high temperature coating such as heat-sensitive materials such as plastic, aluminum, copper composites that are easy to oxidize.

Using such a low temperature spray coating method, the carrier 30 on which the functional particles 40 are supported is coated on the substrate 10 installed on the wall or the bottom to form the skin layer 20. According to the low temperature spray coating method, the skin layer 30 coated with the carrier 30 including the functional particles 40 may be formed not only on a general tile but also on a relatively hard material such as marble.

As described above, according to the block structure of the present invention, by forming the skin layer 20 with the carrier 30 carrying the particles 40 having the eco-friendly function on the substrate 10, more functional particles ( 40) is exposed to the outside, the function can be properly exhibited. In addition, since the functional particles 40 are supported on the carrier 30, the functional particles 40 absorbed into the block structure or buried by the binder can be significantly reduced. In addition, the block structure of the present invention may impart various functions according to the functional particles 30 contained in the carrier 30.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but many variations and modifications may be made without departing from the scope of the present invention. It is possible.
