Description

Luminous sidewalk block having water permeability and method of manufacturing it {Luminescence Pavement Tile Having Water Permeability and Method of Manufacturing It}

The present invention relates to a light-emitting sidewalk block with water permeability and a method of manufacturing the same.

The technology of luminescent sidewalk blocks that accumulate light energy and then emit light is known. Photoluminescent sidewalk blocks can absorb sunlight or artificial light and emit light in dark places.

Photoluminescent sidewalk blocks can store absorbed natural and artificial light energy without consuming electrical energy, provide brightly distinguishable visible light in dark environments, and serve as lighting and decorative lighting. The light storage and emission function gives light-emitting functions to general sidewalk tiles and boundary blocks, gradually expanding the application field of the product.

In Patent Document 1, a base layer formed of base mortar (10; hereinafter referred to as the reference number in Patent Document 1), located on top of the base layer, contains water, cement, silica sand, organic-inorganic hybrid photoluminescent aggregate, and a high-performance AE water reducing agent. It is composed of a surface layer portion (30) formed of surface mortar, wherein the surface layer mortar contains 20 to 40 parts by weight of water, 80 to 100 parts by weight of cement, 300 to 350 parts by weight of silica sand, and 10 to 30 parts by weight of organic-inorganic hybrid photoluminescent aggregate. It is composed of 05 to 2 parts by weight of high-performance AE water reducer.

However, in Patent Document 1, the surface layer 30 is constructed using cement and silica sand along with luminous aggregates with a light-emitting function, so the cement and silica sand will act as an obstacle in the path of light absorption and light emission, so it will not have sufficient luminance. There is a problem that cannot be resolved.

On the other hand, in Patent Document 2, the upper block 120 is composed of epoxy resin 122 and luminescent artificial stone 130 molded on the upper part of the lower block 110 (hereinafter referred to by reference numerals in Patent Document 2), and the epoxy resin ( By placing the light-emitting artificial stone 130 inside the layer made of 122), it has a luminescent and light-emitting function.

However, in the light-emitting sidewalk block of Patent Document 2, the upper block 120 must be manufactured so that at least the light-emitting artificial stone 130 touches the pedestrian's feet first on a surface that is entirely made of epoxy resin. Otherwise, due to the nature of the smooth epoxy resin, ground friction is insufficient. There is a problem that pedestrians can easily slip.

In addition, the light-emitting sidewalk block of Patent Document 2 has no water permeability due to the epoxy resin layer, and accordingly, there is a problem in that during rainy weather, a water film is likely to stagnate for a long period of time on the surface of the sidewalk block to the extent of causing pedestrians to slip.

Hereinafter, a method of manufacturing a light-emitting sidewalk block (1) with water permeability according to an embodiment of the present invention will be described.

1. Production of luminescent particles

According to one embodiment of the present invention, luminescent particles are first manufactured using transparent glaze powder or/and transparent glass powder and luminescent pigment.

Luminescent pigments include luminescent phosphors doped with rare earth elements using SrAl ₂ O ₄ , Sr ₄ Al ₁₄ O ₂₅ , and Sr ₂ MgSi ₂ O ₇ as a fluorescent host, and are revived with the growth of particles in the host. It may contain a flux that improves luminous efficiency by promoting diffusion of the activator and co-activator.

Moreover, the luminescent pigment can control the luminous color depending on the composition of the luminescent phosphor. For example, a strontium aluminate-based (SrAl ₂ O ₄ ) fluorescent matrix that emits yellow green light, and a strontium aluminate-based (Sr ₄ Al ₁₄ O ₂₅ ) fluorescent matrix that emits blue green light. And, a magnesium silicate strontium silicate (Sr ₂ MgSi ₂ O ₇ ) fluorescent matrix that emits sky blue light can be used as a component of the luminescent phosphor. Here, the strontium aluminate-based fluorescent matrix refers to a complex oxide containing strontium (Sr), aluminum (Al), and silicon (Si) as components of the matrix, and the magnesium strontium silicate-based fluorescent matrix refers to strontium (Sr), It refers to a complex oxide containing magnesium (Mg) and silicon (Si) as parent components.

yellow-green luminescence

The luminescent phosphor is made by adding Dy ³⁺ as a co-activator to the base material SrAl ₂ O ₄ using Eu ²⁺ as an activator and doping it with Eu ²⁺ /Dy ³⁺ ions, resulting in SrAl ₂ O ₄ :Eu ²⁺ ,Dy ^{3 +} Manufactured with excellent afterglow characteristics and chemical stability, the light-emitting layer can emit yellow-green light.

As known to those skilled in the art, the intensity of light emission increases as the concentration of Eu ²⁺ ions increases. When the concentration of Eu ²⁺ ions increases beyond a certain range, light emission occurs due to a concentration quenching effect. The intensity gradually decreases. In addition, after blocking the excitation energy from sunlight or electric lights (in other words, in a dark environment), Eu ²⁺ ion, which is an activator, is added to the matrix by trapping holes by Dy ³⁺ added as a co-activator. Due to the energy transfer of , it affects the long afterglow characteristics. In other words, a luminescent phosphor doped with Eu ²⁺ and Dy ³⁺ simultaneously has phosphorescence characteristics with a long afterglow time.

Specifically, SrAl ₂ O ₄ :Eu ²⁺ ,Dy ³⁺ is 45 to 55 parts by weight of alumina (Al ₂ O ₃ ), 45 to 55 parts by weight of strontium oxide (SrO), and 5 to 8 parts by weight of boric acid (H ₃ BO ₃ ). It is preferred that the composition includes 2 to 5 parts by weight of europium oxide (Eu ₂ O ₃ ) and 0.5 to 2 parts by weight of dysprosium oxide (Dy ₂ O ₃ ).

In addition, the properties of luminescent phosphors are affected not only by synthesis conditions such as temperature, time, and atmosphere, but also by activators, co-activators, and fluxes added to the base material. Here, boric acid is used as a flux to promote the granular growth of the matrix and the diffusion of the activator and co-activator into the matrix during firing. Even with a small amount of activator and co-activator, the luminous intensity and attenuation rate of luminescence of the luminous tile are increased. It helps to realize high-efficiency light emitting performance.

turquoise glow

The luminescent phosphor is Sr ₄ Al ₁₄ O ₂₅ :Eu ² , which is doped with Eu ²⁺ /Dy ³⁺ ions by adding Dy ³⁺ as a co-activator to the phosphor using Eu ²⁺ as an activator in the base material Sr ₄ Al ₁₄ O ₂₅ . ⁺ , Manufactured from Dy ³⁺ , it has excellent afterglow characteristics and chemical stability, allowing the light-emitting layer to emit blue-green light.

Specifically, Sr ₄ Al ₁₄ O ₂₅ :Eu ²⁺ ,Dy ³⁺ is 58 to 68 parts by weight of alumina (Al ₂ O ₃ ), 32 to 42 parts by weight of strontium oxide (SrO), and 5 parts by weight of boric acid (H ₃ BO ₃ ). It is preferred that the composition includes ~8 parts by weight, 2-5 parts by weight of europium oxide (Eu ₂ O ₃ ), and 0.5-2 parts by weight of dysprosium oxide (Dy ₂ O ₃ ).

light blue luminescence

The luminescent phosphor is ^a phosphor using Eu ²⁺ as an activator to the base _material Sr ₂ MgSi ₂ O ₇ and adding Dy ³⁺ as a co _- activator to the phosphor doped _with Eu ²⁺ /Dy ³⁺ ions. ⁺ , Manufactured from Dy ³⁺ , it has excellent afterglow characteristics and chemical stability, allowing the light-emitting layer to emit light blue (or light blue-green) light.

Specifically, Sr ₂ MgSi ₂ O ₇ :Eu ²⁺ ,Dy ³⁺ is 28 to 38 parts by weight of silicon dioxide (SiO ₂ ), 51 to 61 parts by weight of strontium oxide (SrO), and 6 to 16 parts by weight of magnesium oxide (MgO). It is preferred that the composition includes 5 to 8 parts by weight of boric acid (H ₃ BO ₃ ), 2 to 5 parts by weight of europium oxide (Eu ₂ O ₃ ), and 0.5 to 2 parts by weight of dysprosium oxide (Dy ₂ O ₃ ).

Transparent glaze powder or/and transparent glass powder (hereinafter, 'transparency' does not require complete transparency as long as visible light transmission is guaranteed and is a broad concept including translucency) and luminescent pigment are fired at a temperature of 700 ~ 1000 ℃. Then, it is pulverized to a particle size of 0.3 to 1.2 mm to produce luminescent particles.

It is impossible to create luminescent sidewalk blocks using luminescent pigments directly. Since the luminescent pigment deliquesces and loses its luminescent performance when exposed to water, the luminescent pigment and glaze or glass are sintered and then pulverized. Using glass powder has the advantage of being able to utilize waste and being inexpensive to procure. However, because the sources of waste glass such as plate glass or glass bottles are different, it is difficult to guarantee quality, and brightness and color may vary between luminous sidewalk blocks during production, so caution is required. Therefore, using glass powder as a raw material may be suitable for small quantity production, whereas transparent glaze powder may be most suitable for mass production. For example, the composition of the transparent glaze is as follows.

quartz calcium oxide potassium oxide sodium oxide boron oxide aluminum oxide stronium oxide SiO ₂ CaO _K2O Na ₂ O B ₂ O Al ₂ O ₃ Sro

In order to make the appearance and color of the light-emitting layer more beautiful, colored glass colorants or ceramic colorants can be appropriately added.

Then, mix 10 to 30% by weight of luminescent glaze with 70 to 90% by weight of transparent glaze powder or clear glass powder (or 70 to 90% by weight of transparent glaze powder and clear glass powder combined).

The raw materials mixed with transparent glaze powder or/and transparent glass powder and luminescent pigment are placed in a sagger tray and fired in a kiln. The temperature is 700 ~ 1000 ℃, the firing time can be 1 ~ 2 hours, and the specific temperature and time varies depending on the output of the kiln. The fired luminescent stone is in the form of large lumps, and it is appropriate to crush it using a crusher, etc. to obtain luminescent particles with a particle size of 0.3 to 1.2 mm.

According to the present invention, although the production technology of the luminescent sidewalk block is relatively simple, it has the advantage of being able to be produced by recycling waste slag, glass, ceramics, crushed stone and other scrap in accordance with national energy policy and environmental protection policy.

2. Manufacturing of luminescent pellets

Light-emitting particles and a transparent binder are mixed and granulated using a granulator to produce a number of light-emitting pellets. When mixing the luminescent particles and the transparent binder, 70 to 85% by weight of the luminescent particles and 15 to 30% by weight of the transparent binder are mixed. The transparent binder allows multiple small light-emitting particles to adhere to each other to form spherical light-emitting pellets, and promotes adhesion between the light-emitting pellets (12a; see Figure 1) when forming the light-emitting layer 12 in the future and the base layer. Adhesion between (11) and the light emitting layer (12) is promoted.

The luminescent binder is an adhesive whose main material is unsaturated polyester. Additionally, a curing agent and an accelerator for curing the adhesive may be used, and are preferably comprised of 15 to 30 parts by weight of unsaturated polyester, 0.3 to 1 part by weight of the curing agent, and 0.1 to 0.5 parts by weight of the accelerator.

A staleness process can be added by leaving the mixture in a cool place for 1 to 2 hours. In particular, if a small amount of liquid raw material is added as in the present invention, it may be difficult to mix the powder (luminescent particles) and liquid raw material uniformly. The mixed raw material is sealed for a certain period of time to allow the liquid raw material to sufficiently penetrate and mix.

According to the present invention, in order to provide water permeability to the light-emitting layer 12, approximately spherical light-emitting pellets 12a with a particle diameter larger than the light-emitting particles are first manufactured. These light-emitting pellets have an outer diameter of 1.5 to 3 mm and are smooth or A spherical shape with an irregular surface is preferred. Light-emitting pellets are granulated so that the light-emitting particles have a larger particle size in order to provide or increase the water permeability of the light-emitting layer.

Roller Extrusion Granulation

Figure 2 shows an example of a roller extrusion granulator. The mixture of luminescent particles and transparent binder mixed as described above is passed between the roller pairs 31a and 31b of the roller extrusion granulator 30 to form pellets.

According to the particle size requirements, select a pair of rollers (31a, 31b) with small holes on the surface, put the prepared raw material (A) into the inlet of the roller extrusion granulator (30), and push it to the outlet to make pellets (12a). . You can use this device when you want to accurately create the right particle size, and using this device has the advantage of being able to produce a lot of material continuously.

Granulation using rotating disk

Meanwhile, in manufacturing luminescent pellets, a granulator with a rotating disk can also be used. Figure 3 shows an example of a rotating disc-shaped granulator 40 using a rotating disc.

The rotating disk 41 of the granulator 40 can rotate in an inclined state, and the mixture of luminescent particles and transparent binder has viscosity and can be aggregated into larger particles (granules) due to the action of the rotating disk. Due to the influence of gravity and centrifugal force, larger particles move to the edge of the rotating disk 41, and the angle and speed of the rotating disk 41 are adjusted to create the necessary pellets (granules). Additionally, dried luminescent particles or the above mixture may be placed on a rotating disk and rotated to spray a transparent binder (liquid) through the spray nozzle 42. Under the action of gravity and centrifugal force, granules (pellets) of a size that meets the requirements are moved to the edge of the rotating disk 41 and can be sorted. This method is not continuous production, so it is more suitable for small quantity production.

The luminescent pellets processed in the above manner can be immediately put into a subsequent process or placed in a wrapper or container and placed in a cool place for temporary storage. Since they have not yet fully hardened, it is best to use them within, for example, 4 hours. If stored for a long time, the pellets become hard and the adhesion between the pellets and the adhesion to the base layer may decrease even through the subsequent pressurized lamination process (secondary pressing to be described later).

3. Molding of luminous sidewalk blocks, etc.

Except for the preparation process of the above-mentioned materials, the production process of luminescent sidewalk blocks (particularly molding, demolding, and hardening) is basically the same or similar to the process of existing general non-fired sidewalk blocks, so existing sidewalk block production facilities can be used as is. Available. And, except for the manufacturing process of the luminescent particles, all are manufactured through a non-baking process.

First, as in the manufacturing process of a general sidewalk block, a mortar made of a mixture of water, concrete, and aggregate is placed in a mold and first pressing is performed by pressing from the top to form the base layer 11. For example, crushed stone particles with a particle size of 2 to 5 mm and river sand with a particle size of 1 to 2 mm and high-strength cement are preferred. The larger the particle size of crushed stone and river sand, the larger the porosity and the better the permeability, but the lower the strength, so an appropriate particle size is selected.

Then, a plurality of light-emitting pellets (not yet fully cured) prepared as above are press-laminated on top of the base layer 11 to form the light-emitting layer 12. Optionally, a small amount of additional transparent binder (liquid) may be mixed in addition to the luminescent pellets to form an additional transparent binder film on the surface of the luminescent pellets. After the above-mentioned primary pressing is performed, a plurality of light-emitting pellets are loaded into the same mold and then secondary pressing is performed by pressing from the top to form the light-emitting layer 12. Therefore, the light-emitting layer 12 does not contain aggregate or cement, and a plurality of light-emitting pellets have voids (S) for water permeability due to the adhesive force of the transparent binder (transparent binder of the not fully hardened light-emitting pellet itself or an additionally applied transparent binder). and are bonded to each other.

After the prepared luminescent pellets are evenly arranged on the surface of the first pressed base layer, molding, demolding, and hardening (curing) by secondary pressing are performed sequentially. After the pellets for the luminescent layer are pressed, the gap between the pellets has excellent water permeability. will have The larger the pellet, the better the water permeability, but the strength decreases. When the particle size of the luminescent pellet is 1.5 to 3 mm, excellent water permeability and strength are shown. If the curing time is too short, the product will lack strength, so approximately 4 to 6 days is preferred, and a cool location not exposed to the sun is preferred.

The product of the present invention is non-toxic, harmless, non-radioactive, corrosion resistant, durable, and can be easily manufactured to have the same or similar physical and chemical indicators as regular sidewalk blocks.

The present invention has been described in detail through examples, but this is for the purpose of specifically illustrating the present invention. The light-emitting tile according to the present invention, the method of manufacturing the same, and the light-emitting structure using the light-emitting glaze powder are not limited thereto, and the present invention It is clear that modifications or improvements are possible by those with ordinary knowledge in the field within the technical ideas of .
