<Example>

1 is a flow chart illustrating a method of manufacturing an eco-friendly photoluminescent color aggregate according to an embodiment of the present invention.

As shown, the eco-friendly photoluminescent color aggregate manufacturing method according to an embodiment of the present invention includes an aggregate crushing step (S101), a foreign substance removing step (S102), a particle size separation step (S103), a cleaning step (S104), and a plasma treatment. Step (S105), pigment mixing and stirring step (S106), heating coloring step (S107), protective agent mixing and stirring step (S108), protective agent heating impregnation step (S109), cooling drying step (S110), phosphorescent pigment coating step ( S111).

In the aggregate crushing step (S101), an aggregate composed of one or more of natural stones selected from basalt, granite, dolomite, silica sand, zircon, and germanium is pulverized to an average particle size of 0.5 to 50 mm. To this end, it is possible to pulverize one pulverizer until the aggregate is required, but if the environment permits, the first pulverizer 110a and the second pulverizer 110b are serially connected as shown in FIGS. 8 and 9. It is preferable in terms of crushing quality to pulverize the aggregate step by step by installing a

In the foreign matter removing step (S102), unnecessary fine powders and various foreign matters included together with the pulverized aggregate are removed. To this end, as shown in FIG. 10, while the foreign matter remover 120 vibrates and lifts the aggregate (S) crushed by the diaphragm 121, the blower 123 applies blowing pressure on one side and the duct 124 on the other side. A sucks and removes the foreign material E1 blown by the blowing pressure, and the electromagnet 125 adsorbs and removes the metallic foreign material E2 from the upper side. This process of removing foreign substances is performed by adjusting the time according to the amount of the pulverized aggregate (S). For reference, the vibration plate 121 is installed in a form surrounding a fence 121a composed of a mesh network along the periphery of the upper surface to block the separation of the aggregate (S) from the vibration plate 121, while the blowing pressure or the electromagnet by the blower 123 Allow the magnetic force by (125).

In the particle size separation step (S103), the operation of separating the pulverized aggregate by particle size is performed. To this end, the separator 130 is provided with a plurality of meshes made of pores of different sizes, or a bar for each particle size to filter and separate the pulverized aggregate by particle size.

In the cleaning step (S104), the cleaning device 140a sprays the oxygen water produced in the oxygen dissolver 141 at high pressure to wash the natural stone aggregate separated by particle size. As a result, it is possible to remove even the fine powder remaining on the surface of the natural stone aggregate without being removed in the preceding foreign matter removing step (S102). This process helps to increase the efficiency of subsequent plasma processing operations.

The point to note here is that high-quality oxygen water with high saturation of dissolved oxygen is used to clean natural stone aggregates. Through this, it is possible to quickly sterilize various bacteria existing on the surface of the natural stone aggregate while washing the natural stone aggregate, and thus it becomes possible to provide an eco-friendly phosphorescent color aggregate.

In order to produce high-quality oxygen water, an oxygen dissolver 141 having a unique configuration is used. As shown in Figs. 11 and 12, the oxygen dissolver 141 has a communication tube 20 and an oxygen nozzle 20 And, it comprises a phase conversion module 30, a dissolved module 40, and an oxygen cooling module 50.

The communication pipe 20 serves to first dissolve while being supplied with water, which is water particles in a mist form, and oxygen in a gaseous state by the phase change module 30 and strongly contact and mix. To this end, the communication pipe 20 is connected to an oxygen tank so that the tip of the communication pipe 20 is connected to the phase change module 30 to receive the free water transmitted from the phase change module 30 and is connected to the oxygen nozzle 20. Oxygen in the gaseous state is also supplied from. A protrusion 11 is provided inside the body having a pipe shape to form a narrow venturi tube-shaped flow path at an intermediate point while gradually reducing the inner diameter and then widening it to its original state. As can be seen in FIG. 13, the protrusion 11 induces the free water and oxygen to flow at an increased speed in the relatively narrow flow path 10a due to the Venturi effect and to make strong contact with each other. In addition, chambers 11a and 11b are formed inside the protrusion 11 to receive and temporarily store oxygen by being connected to the oxygen tank through the first supply pipe 62 of the three-way valve 60, and the protrusion 11 A plurality of first injection holes 11c are formed along the circumferential direction of the inner circumferential surface to receive oxygen from the chambers 11a and 11b on the inner circumferential surface of the intermediate point corresponding to the narrowly formed point, and the protrusion 11 ), a plurality of second injection holes 11d for receiving and spraying oxygen from the chambers 11a and 11b are formed along the circumferential direction of the rear end. As a result, it is possible to simultaneously supply oxygen in a gaseous state not only at the oxygen nozzle 20 but also at various points, so that it is possible to more effectively contact the non-constant water. In particular, the oxygen injected through the first injection hole 11c formed at the midpoint of the protrusion 11 allows vigorous contact with the free water flowing at the fastest speed, whereas the protrusion 11 is formed at the rear end of the protrusion 11 Oxygen injected through the second injection hole 11d was made to be in calm contact with the constant water flowing at a relatively slow speed. With such a variety of composition, it is possible to increase the effect of mixing and contacting non-constant water and oxygen, and thereby raise the dissolution rate to a high level from the beginning.

In addition, an axial fan 12 is further provided inside the front end of the communication pipe 20 for transmitting the free water transmitted from the centrifugal fan 32 of the phase change module 30 in the form of a tornado as shown in FIG. 14. When such an axial fan 12 is provided and operated, as shown in FIG. 13, the flow rate of free water and oxygen is rapidly formed by the Venturi effect, and strong contact is made with each other, as shown in FIG. 14. In the form of a powerful whirlwind, a complex action takes place, mixing with oxygen. Therefore, the contact and mixing between the superfine particle state of the free water and the gaseous state of oxygen, and thus the initial oxygen dissolution occurs very quickly and effectively. For reference, it is sufficient to provide the axial fan 12 having the same shape as the fan used in an air circulator recently used in homes. However, in consideration of the fact that the material of the axial flow fan 12 is installed inside a pipe that is continuously exposed to humidity, it should be applied to have enhanced corrosion resistance and durability.

The oxygen nozzle 20 serves to supply oxygen in the communication pipe 20 in accordance with the flow direction of the free water. To this end, the oxygen nozzle 20 is connected to the oxygen tank through the second supply pipe 63 of the three-way valve 60 to receive oxygen, and the end of the communication pipe 20 is passed through the front end wall of the communication pipe 20. It is formed so as to face the flow path narrowly formed by the protrusion 11 while being positioned on the center line of the. Here, the oxygen nozzle 20 is formed from the wall of the communication tube 20 to the center line along the center line of the communication tube 20 from the first nozzle part 21 and the first nozzle part 21 as shown in FIG. It is made of a second nozzle portion 22 that is extended and has its end formed close to the narrow flow path 10a by the protruding portion 11. Such an oxygen nozzle 20 helps to accelerate the flow rate of the water free while injecting oxygen in the vicinity of the narrow flow path 10a by the protrusion 11 in the flow direction of the water free. This greatly contributes to the contact of free water and oxygen at a faster rate in the narrow flow path 10a at the midpoint of the protrusion 11 of the communication pipe 20.

The phase change module 30 serves to convert the liquid water supplied from the tap water P1 into a free form of ultrafine particles. To this end, the phase change module 30 has a body in the form of a pipe that is provided with a flange and communicates between the water supply system P1 and the communication pipe 20, and the liquid water transferred through the water supply system P1 is free from the inside. It is equipped with a spray head 31 for converting and spraying. Such a spray head 31 can be used as it is a spray head 31 (nozzle) applied to a water spray fire extinguishing facility, but it is improved to have enhanced corrosion resistance and durability in consideration of the fact that it is installed inside a pipe that is continuously exposed to humidity. It is preferable to apply. In this way, if the water supplied from the tap water (P1) is not used as it is, and converted into non-constant water in the form of ultrafine particles, it is possible to secure a wide contact area that can be in contact with oxygen, which can significantly increase the dissolution rate. It is very important in that regard.

In addition, a centrifugal fan 32 is provided inside the phase change module 30 for discharging mist-like water that is formed at a low speed while being sprayed from the spray head 31 at a higher speed. In the case of the axial fan 12, if it has a specialized function to push and transmit the free water, the centrifugal fan 32 overcomes the resistance caused by the installation of the spray head 31 and draws out the free water generated in a state of lowering the speed. It can be said that it is suitable for sending out to the centrifugal fan 32. In the present invention, the centrifugal fan 32 and the axial fan 12 are arranged in series in the vicinity, thereby maximizing the advantages of both.

The dissolved module 40 is in a well-mixed state while passing through the communication pipe 20, and serves to maximize the dissolution rate by receiving a mixed water of primary dissolved free water and oxygen. To this end, the dissolved module 40 is connected to the rear end of the communication pipe 20 by a pipe-shaped body to receive the mixed water in which the free water and oxygen are mixed through the communication pipe 20. A plurality of grills 41, 42, 43 in which a plurality of micropores are formed in a form of blocking are arranged in series with a distance apart from each other. According to the drawing, it is shown that three grills (41, 42, 43) are arranged. According to this configuration, when the mixed water passes through the grill (41, 42, 43) layer formed by the grill (41, 42, 43) It is possible to gradually increase the dissolution rate of oxygen to water particles by repeating contraction and expansion every time, and each time the mixed water passes through each grill (41, 42, 43), the grill (41, 42, 43) In the spaced spaces 44a, 44b, and 44c formed at the rear, turbulent flow occurs, and oxygen contact with water particles is made more active. This makes it possible to increase the dissolution rate of oxygen in water to a supersaturated state.

The oxygen cooling module 50 serves to quickly cool the oxygen supplied to the communication pipe 20 in the middle. To this end, the oxygen cooling module 50 has an inlet 52a and an outlet 52b to receive oxygen from the oxygen tank and then discharge it to the communication pipe 20 through the inlet pipe 61 of the three-way valve 60. The inner tube 51, the outer tube 52 that surrounds the inner tube 51 and cools the outer tube 51, and the inner tube 51 is formed long in a rod shape along the central axis of the inner tube 51 inside the inner tube 51 ) And the cooling rod 53 that cools the oxygen passing through the inside of the cooling rod 53, and is formed in a spiral shape along the outer circumferential surface of the cooling rod 53 to guide oxygen to pass through the inner tube 51 in a spiral shape. It is provided with a cooling fin (54) for cooling.

According to the configuration of the oxygen cooling module 50, it is possible to quickly lower the temperature of the supplied oxygen, so that the mixing of the misty free water and oxygen in the communication pipe 20 can be performed in a lower temperature atmosphere. As such, when a lower temperature atmosphere is formed in the free water and oxygen, the dissolution rate of oxygen increases.

In the plasma treatment step (S105), in order to increase the coloring efficiency of the pigment for the aggregate, the surface of the cleaned aggregate is subjected to plasma treatment before mixing the aggregate and the pigment. To this end, the atmospheric pressure plasma processing device 140b may be simply installed on a line without the need to implement it in a vacuum device or a large-sized mechanical device. At this time, at room temperature, the discharge area is 3kw, and the amount of nitrogen and oxygen gas is adjusted to about 60:1 for plasma generation, and the transport speed of the aggregate is about 1 to 2m per minute, while the plasma treatment time can be set to 1 to 5 minutes. . By such plasma treatment, an etching phenomenon appears on the surface of the aggregate, which was initially smooth, and micro-craters in a rough form are formed, thereby increasing the value of the root mean square (RMS) roughness. This provides conditions in which the binding of the pigment component to the aggregate surface can be easily achieved. If the work of heating and coloring by mixing and stirring the aggregate and the pigment without the above-described plasma treatment step (S105) is performed immediately, the amount of pigment should be increased, and the time required for mixing and stirring and heating coloring should be significantly increased. There are difficulties. However, through such plasma treatment, the amount of pigment and the time required for coloring can be drastically reduced, and the overall coloring quality is also improved.

In the pigment mixing and stirring step (S106), the plasma-treated aggregate and the pigment are mixed and sufficiently stirred in a dedicated first stirrer 150a. Thereby, the pigment is uniformly dispersed and applied on the surface of the aggregate in a sufficient amount.

In the heating coloring step (S107), the aggregate and the pigment stirred in the first stirrer 150a are heated in the coloring furnace 160a to stably color the pigment in the aggregate. At this time, the heating temperature is suitable in the range of 200℃ or higher to 1000℃.

In the protective agent mixing and stirring step (S108), a vegetable resin, a UV stabilizer, and a curing accelerator are mixed and stirred in the colored aggregate to coat the surface. The use of the vegetable resin, UV stabilizer, and curing accelerator is to protect the colored pigments from flying away from the aggregate and to preserve the gloss, where these are not applied together with the pigment in the coloring step, but are applied in stages. . As a result, when coloring the pigment, it has the advantage that it is possible to perform coloring by setting the heating temperature more freely without taking into consideration the limitation of heating due to the epoxy resin, and the pigment is protected by covering the surface after the pigment is completely colored. It is also preferable in terms of protecting the surface of the colored aggregate. Here, 50 to 90% by weight of the aggregate, 1 to 10% by weight of pigment, 1 to 30% of vegetable resin, 0.1 to 5% of UV stabilizer, and 0.1 to 5% by weight of a curing accelerator are mixed.

In the protective agent heating impregnation step (S109), the aggregate material coated with the surface of the vegetable resin, UV stabilizer, and curing accelerator is introduced into the heating furnace 160b to be impregnated. At this time, the first heating is performed at a temperature of 300 to 780°C, followed by secondary heating at a temperature of 300 to 780°C.

In the cooling drying step (S110), the aggregate impregnated with the protective agent is cooled and dried in the heating furnace 160b. To this end, as shown in FIG. 4, the aggregate heated in the heating furnace 160b is passed through a cooling dryer 170 installed along a conveyor, which is a conveying device 190. The cooling dryer 170 is composed of a box-shaped body 171 that provides a passage through which a conveyor for transporting aggregates can pass, and a plurality of blowing fans 172 arranged along the conveyor in the box-shaped body 171 to be heated. It effectively cools and dries the aggregated material.

In the photoluminescent pigment coating step (S111), the photoluminescent pigment is applied in an amount of 10 to 40L per ^{m 2} using the first photoluminescent pigment application device 180 including a high-pressure sprayer on the cooled and dried aggregate. At this time, the photoluminescent pigment is first applied, the photoluminescent pigment is applied second after the first applied photoluminescent pigment is fixed, and when the second applied photoluminescent pigment is fixed, the photoluminescent pigment is applied third. As a result, the thickness of the phosphorescent pigment can be secured to a certain value or more, and the period of light emission by the phosphorescent pigment can be increased, thereby enabling semi-permanent use.

Here, the phosphorescent pigment refers to a pigment that absorbs, stores, and emits light inside, and absorbs and accumulates energy from natural light and artificial light used in daily life such as the sun, mercury lamps, fluorescent lamps, and incandescent lamps. It has the property of emitting fluorescent light in a dark place. As such a photoluminescent pigment, it develops a yellow-green color, has relatively excellent safety, and is low-cost, so it is possible to use an emulsified zinc-based (ZnS: Cu) pigment that is widely used today. Preferably, strontium alu that activates europium ions. Mart (SrAl2O4: Eu, Dy) is used. In the case of strontium alumina (SrAl2O4: Eu, Dy), afterglow luminance and afterglow time are 10 times or more than zinc sulfide pigments.

On the other hand, when the photoluminescent pigment application step (S111) is completed, a photocatalyst may be applied. In the case of a photocatalyst, titanium oxide (TiO ₂ ) is in mind, but it can be provided as a composite of titanium oxide and tin oxide to which metal ions are added, or a composite of a junction structure of titanium oxide and metal tungsten oxide in order to increase the efficiency in visible light. have.

As described above, when the aggregate passes through the first phosphorescent pigment application device 180, the production of the color aggregate is completed.

Subsequently, a description will be given of a color aggregate module manufactured by using the eco-friendly photoluminescent color aggregate according to the present invention as a parent. In the case of color aggregate modules, it is a member that can be directly applied to permeable sidewalk blocks, eco-friendly construction/civil engineering pavements, and street tree protection plates.

Figure 2 is a partial perspective view of a color aggregate module according to an embodiment of the present invention, Figure 3 is a partial cross-sectional view for explaining the hierarchical structure of the color aggregate module according to an embodiment of the present invention, Figure 4 is an embodiment of the present invention It is an exploded perspective view of the color aggregate module by. And Figure 5 is a cross-sectional reference view for explaining the internal configuration of the module reinforcement in the color aggregate module according to an embodiment of the present invention.

As shown, the color aggregate module 300 according to the embodiment of the present invention comprises a module body 310 formed of a color aggregate and is bonded to a lower surface of the module body 310 to provide a convex body 310. ) It is interposed between the module reinforcement part 320 to ensure convenient construction while reinforcing strength so as not to be damaged, and the module reinforcement part 310 and the module reinforcement part 320 to prevent damage caused by external impact. It consists of a combination of layers 330.

The module main body 310 is partially shown in the drawing and may be seen as a block-shaped body, but is formed in a wider plate shape according to the construction area. Note that the module main body 310 is formed of a color aggregate. To this end, a color aggregate is prepared by coloring a pigment in the aggregate obtained by pulverizing at least one natural stone selected from basalt, granite, dolomite, silica sand, zircon, and germanium, followed by mixing and stirring the color aggregate, a polyurethane resin, and a curing accelerator, It is prepared by pressing a mixture of agitated color aggregate, polyurethane resin, and curing accelerator. In this way, when the module body 310 is made of a color aggregate, it has pores that can be naturally permeable and produces a unique color of the color aggregate that harmonizes with the surrounding environment. Moreover, a phosphorescent pigment is applied to the surface of the color aggregate constituting the module body part 310 _{to remove contamination of nitrogen oxides (NO X} ) caused by exhaust gas generated from automobiles traveling on the road, purify the air, and effectively prevent slipping. It even has a function.

The module reinforcement part 320 reinforces the strength of the module body part 310 and helps to construct the module body part 310 in a standardized form. The module reinforcement part 320 is formed of a thin plate-shaped body that is bonded to the lower surface of the module body part 310 and has a plurality of permeable holes 321.

Mortar 350 for manufacturing the module reinforcement part 320 is blast furnace slag cement 49 to 55% by weight, PE bonded yarn 0.05 to 0.2% by weight, polymer 0.2 to 1.5% by weight, thickener 0.02 to 0.1% by weight, foaming agent 0.05 to It can be noted that it consists of 0.2% by weight and 40-50% by weight of fine aggregates, so that no toxic Portland cement is used. In addition, the PE ply yarn included in the mortar 350 is provided with short fiber PE plying yarns 351 and 352 having a length of 3 to 6 cm with both ends bent in a ring shape to increase bonding and tensile strength as shown in FIG. 5 to be uniformly dispersed. . Epoxy layer 353a formed by coating epoxy, a material that improves bonding properties with other components, particularly mortar, on the surfaces of short-fiber PE braids 351 and 352, and surface bonding and flame retardancy to the epoxy layer 353a For improvement, a plurality of inorganic particle protrusions 353b are formed. When such a unique single fiber PE plying yarn (351,352) is included in the mortar, a number of single fiber PE plying yarns (351, 352) are entangled with each other by the both ends bent in a ring shape, forming a module reinforcement part with strong brittleness and high tensile strength ( 320).

The impact relief layer 330 is formed by uniformly applying foamed urethane to a predetermined thickness on the upper surface of the module reinforcement part 320. If the module reinforcing part 320 is bonded to the module body part 310 before the urethane foam of the impact reducing layer 330 is cured, the strength reinforcing layer 324 is naturally formed while smoothly bonding between the two.

In this way, by forming the shock-absorbing layer 330 of foamed urethane material, the module body part 310 and the module reinforcing part 320 having different surface textures can be more smoothly joined. Because of this, it becomes possible to minimize the damage problem caused by cracking or cracking.

In the case of the above-described color aggregate module, the module body part 310, the module reinforcement part 320, and the shock mitigating layer 330 may be integrally manufactured from the beginning in a factory, or may be integrated through field construction. Depending on the site situation, the configuration of the module reinforcement part 320 and the impact relief layer 330 may be limitedly omitted.

Subsequently, a method of manufacturing a color aggregate module according to an embodiment of the present invention will be described below with reference to FIGS. 6 to 15 and 16A to 16D.

Color aggregate module manufacturing method according to an embodiment of the present invention, first, as shown in Figure 6 in order to manufacture the module body 310, the color aggregate manufacturing step (S11), the color aggregate and the polyurethane resin mixing stirring step (S12 ), a release agent injection step (S13), a pressure molding step (S14), a demoulding step (S15), and a curing step (S16).

In the color aggregate manufacturing step (S11), an eco-friendly photoluminescent color aggregate is manufactured by coloring a pigment on the aggregate obtained by pulverizing natural stone and applying even a photoluminescent pigment. In the case of eco-friendly phosphorescent color aggregate manufactured at this stage, it exhibits beautiful color with little or no fading or discoloration, and it is applied to various buildings and civil engineering facilities to realize the beauty of phosphorescent light even at night, while achieving energy saving effect and detecting harmful substances. As shown in Figs. 8 and 9, it is an eco-friendly material, and as the aggregate is transferred by the conveyor, which is the transfer device 190, the first pulverizer 110a and the second pulverizer 110b, foreign matter remover 120, Separator 130 by particle size, plasma processing device 140b, first stirrer 150a and second stirrer 150b, coloring furnace 160a, heating furnace 160b, cooling dryer 170, first phosphorescent pigment It is manufactured through the applicator 180. Since the color aggregate manufacturing method has been described in detail above, further detailed description will be omitted.

In the stirring step of mixing the color aggregate and the polyurethane resin (S12), the color aggregate prepared in the previous step, the two-component polyurethane resin, and the curing accelerator are mixed and stirred in the third agitator 210. At this time, 70 to 95% by weight of the color aggregate, 4 to 30% by weight of the polyurethane resin, and 0.001 to 3% by weight of the curing accelerator are mixed. Here, the polyurethane resin mixed with the colored aggregate completely replaces the cement and serves to bind the colored aggregate with high strength, and the curing accelerator accelerates the curing of the polyurethane resin to shorten the curing time.

In the releasing agent spraying step (S12), the water-type releasing agent is sprayed into the first molding machine 220 before the mixture of the stirred color aggregate, polyurethane resin, and curing accelerator is added to the first molding machine 220. Here, the moisture release agent is intensively sprayed onto the upper and lower molds of the first molding machine 220. This process prevents the adhesion of the polyurethane resin and the color aggregate to the first molding machine 220 to facilitate the demolding of the module body part 310 molded from the first molding machine 220, thereby reducing the overall process time. It helps.

In the pressure molding step (S14), a mixture of the stirred color aggregate, polyurethane resin, and curing accelerator is put into the first molding machine 220 and then pressurized to form the module body 310.

In the demolding step (S15), the module main body 310 molded in the first molding machine 220 is demolded from the first molding machine 220. The demolding of the module body 310 is easily performed without the problem of adhesion of the polyurethane resin or the color aggregate due to the moisture release agent sprayed in the previous step.

In the curing step (S16), the module main body 310 removed from the first molding machine 220 is gradually passed through the first curing machine 230 installed along the conveyor, which is the transfer device 190, or stored for a sufficient time. It is cured while doing. The module body portion 310 cured in this way is measured and packaged while passing through the packaging machine 240. Here, the first curing device 230 is configured in a form in which a plurality of cooling fans are installed, and the cooling fan may be selectively used to control a curing time.

Thereby, it is possible to obtain an eco-friendly non-toxic module main body 310.

In order to continuously manufacture the module reinforcement part 320, as shown in FIG. 7, a mortar manufacturing step (S21), a mortar stirring step (S22), a pressure molding step (S23), a demolding step (S24), a curing step (S25) And the photoluminescent pigment application step (S26) proceeds.

In the mortar manufacturing step (S21), 49 to 55% by weight of blast furnace slag cement, 0.05 to 0.2% by weight of PE blend, 0.2 to 1.5% by weight of polymer, 0.02 to 0.1% by weight of thickener, 0.05 to 0.2% by weight of foaming agent, and 40 to 50 of fine aggregates To prepare a mortar containing% weight. It can be noted that this composition does not use any toxic Portland cement.

Herein, as shown in FIG. 5, the PE ply yarn is provided as short fiber PE ply yarns 351 and 352 having a length of 3 to 6 cm in which both ends are bent in a ring shape to increase bonding and tensile strength, and is added in a uniformly dispersed form.

Here, the short-fiber PE ply yarns (351, 352) with both ends bent in a ring shape apply a tensile force to the high elastic PE ply yarns (35) used as fishing lines in the market, and in that state, the PE ply yarns (35) are multiplied. It is produced by a unique process that cuts it shortly. For this purpose, as shown in FIG. 15, several rows of PE plying strings 35 are simultaneously stretched by the holder W1, and in that state, several blades W4a are formed at intervals of 3 to 6 cm as shown in FIGS. 16C and 16D. It is cut with an excitation bite (W4). At this time, before cutting the PE braid file 35, while moving the spray nozzle (W2) as shown in FIG. 16A while applying the tensile force, spray the epoxy and apply it, and before the applied epoxy is cured, 10 to 100 as shown in FIG. 16B. The process of forming protrusions 353b by inorganic particles on the surface of the PE braided string 35 by spraying aluminosilicate with a particle diameter of ㅅm with a spray (W3) is additionally performed in the middle.

As a result, as shown in FIG. 5, the epoxy layer 353a formed by applying epoxy, which is a material that improves bonding properties with other components of the mortar, is applied to the surface of the short-fiber PE ply yarns 351 and 352, and the epoxy layer 353a. In order to improve surface adhesion and flame retardancy, a number of inorganic particle protrusions 353b are formed to form short fiber PE plying yarns 351 and 352 having a unique shape. When such unique single fiber PE plying yarns 351 and 352 are included in the mortar, numerous single fiber PE plying yarns 351 and 352 are entangled with each other by both ends bent in a ring shape, thereby contributing to having an integrated internal structure as a whole. Thus, the bonding property of the mortar forming the module reinforcement part 320 is improved by the structural characteristics centering on the single fiber PE plying yarns 351 and 352, and the tensile strength of the module reinforcement part 320 formed therefrom is improved. .

Here, in the case of the single-fiber PE plying yarns 351 and 352, it is preferable not to provide a single length, but to provide two types of short and long relative lengths. While the length of the short-fiber PE ply (351,352) does not exceed the range of 3 to 6 cm, one type is the first short-fiber PE ply yarn 351 having a length of 3 to 4 cm, and the other type has a length of 5 to 6 cm. It is provided with a second short fiber PE ply yarn (352). As a result, the short-fiber PE plying yarns 351 and 352 can be uniformly diffused in the same space and added at a higher density. In order to provide the short-fiber PE ply yarns 351 and 352 as the first short-fiber PE plying yarn 351 and the second short-fiber PE plying yarn 352 having different lengths, the bite cuts the PE yarns When preparing the ply yarns 351 and 352, simply use two types of bites with different blade intervals.

In the case of blast furnace slag cement in the mortar, it contains blast furnace slag as the largest component by weight, and it is possible to generate _{ethrinzite (3CaO·Al 2} O ₃ ·3CaSO ₄ ·32H _{2 O) through hydration reaction.} It contains phosphorus, lime and anhydrous gypsum as essential ingredients.

Looking specifically at the components of the blast furnace slag cement, 38 to 70% by weight of blast furnace slag, 5 to 15% by weight of gypsum, 6 to 20% by weight of auin, 0.3 to 2.5% by weight of water reducing agent or superplasticizer, and the balance Portland cement Including, but the Portland cement is included in an amount of less than 13% by weight so as to be less than 8% by weight of the total mortar composition, so that practical cementation of Portland cement can be achieved.

In the mortar stirring step (S22), the mortar prepared in the previous step is stirred in the fourth stirrer 240. At this time, the added short fiber PE plying yarns 351 and 352 are uniformly dispersed in the mortar.

In the press-molding step (S23), the mortar prepared in the previous step and then stirred is injected into the second molding machine 250 and then pressurized to form the module reinforcement part 320.

In the demolding step (S24), the module reinforcement part 320 molded in the second molding machine 250 is demolded from the second molding machine 250.

In the curing step (S25), the module reinforcement part 320 removed from the second molding machine 250 is gradually passed through the second curing machine 260 installed along the conveyor, which is the transfer device 190, or stored for a sufficient time. It is cured while doing.

In the photoluminescent pigment application step (S26), a photoluminescent pigment is applied in an amount of 10 to 40L per ^{m 2} using a second phosphorescent pigment application device 270 including a high pressure sprayer to the cured module reinforcement part 320 do. At this time, the photoluminescent pigment is first applied, the photoluminescent pigment is applied second after the first applied photoluminescent pigment is fixed, and when the second applied photoluminescent pigment is fixed, the photoluminescent pigment is applied third. As a result, the thickness of the phosphorescent pigment can be secured to a certain value or more, and the period of light emission by the phosphorescent pigment can be increased, thereby enabling semi-permanent use.

Here, as the photoluminescent pigment, an emulsified zinc-based (ZnS: Cu) pigment may be used as in the case of preparing the color aggregate, and preferably strontium alumina (SrAl2O4: Eu, Dy) activated with europium ions is used. use.

When the photoluminescent pigment application step (S26) is completed, a photocatalyst may be applied. In the case of a photocatalyst, titanium oxide (TiO ₂ ) is in mind, but it may be provided as a composite of titanium oxide and tin oxide to which metal ions are added, or a composite of a junction structure of titanium oxide and metal tungsten oxide in order to increase the efficiency in visible light. have.

Accordingly, it can be said that the manufacturing of the module reinforcement part 320 is completed. When the completed module reinforcement part 320 is combined with the module body part 310 in the combining part 280, the color aggregate module 300 according to the embodiment of the present invention is completed. At this time, the foam urethane is uniformly applied to the lower surface of the module reinforcement part 320 to have a predetermined thickness to form the shock mitigating layer 330, and then, the foamed urethane may be bonded to the previously made module body part 310 before being completely cured. This allows the shock-absorbing layer 330 formed of urethane foam to be completely bonded to each other despite the surface heterogeneity of the module reinforcement part 320 and the module body part 310. However, if the urethane foam is applied to the module body 310, the water-permeable pores formed by the color aggregate are blocked, so be careful to apply it to the module reinforcement part 320 in which the water-permeable hole 321 is formed.

As a result, a color aggregate module using an eco-friendly phosphorescent pigment color aggregate, which has excellent water permeability and a light emitting function by a phosphorescent pigment, while improving the aesthetics of the city by coating natural stone with beautiful colors in harmony with the surrounding environment is obtained. In the case of color aggregate modules, it can be widely used for permeable sidewalk blocks, eco-friendly construction and civil engineering pavements, and roadway protection plates.

Continuing below, a system for manufacturing a color aggregate module according to an embodiment of the present invention will be described.

As shown in FIGS. 8 to 12, the color aggregate module manufacturing system includes a first grinder 110a and a second grinder 110b for manufacturing the module body 310, a foreign material remover 120, and a separator for each particle size. (130), a cleaning device (140a), a plasma processing device (140b), a first stirrer (150a) and a second stirrer (150b), a coloring furnace (160a), a heating furnace (160b), a cooling dryer (170), The fourth for manufacturing the module reinforcement part 320 together with the one phosphorescent pigment application device 180, the transfer device 190, the third agitator 210, the first molding machine 220, and the first curing machine 230. Equipped with a stirrer 240, a second molding machine 250, a second curing machine 260 and a second phosphorescent pigment application device 270, the manufactured module body 310 and the module reinforcement part 320 are incorporated. It further includes a coalescence part 280 for doing so. Accordingly, it is possible to perform a series of processes for manufacturing an eco-friendly photoluminescent color aggregate module.

Hereinafter, each of the above components will be described in more detail.

The first and second pulverizers 110a and 110b serve to pulverize an aggregate composed of one or more natural stones selected from basalt, granite, dolomite, silica sand, zircon, and germanium to an average particle size of 0.5 to 50 mm. Here, when the first grinder 110a and the second grinder 110b are installed in series and configured to pulverize the aggregate in stages, the load applied to the grinder can be reduced, and it is also preferable in terms of grinding quality of the aggregate.

The foreign material remover 120 serves to remove unnecessary fine powders and various foreign materials included together with the pulverized aggregate. As shown in FIG. 10, the foreign matter remover 120 vibrates and lifts the pulverized aggregate while being supported by the actuator 122, as shown in FIG. 10, and a blower that applies a blowing pressure from one side of the vibration plate 121. (123), a duct 124 that sucks and removes foreign substances blown by the blowing pressure from the other side of the vibration plate 121, and a metallic foreign substance mixed with the pulverized aggregate installed on the upper side of the vibration plate 121. It includes an electromagnet 125 that is adsorbed and removed. According to this configuration, while the foreign matter remover 120 vibrates and lifts the aggregate (S) crushed by the vibration plate 121, the blower 123 applies the blowing pressure on one side, and the duct 124 applies the blowing pressure on the other side. The foreign matter E1 blown by is sucked and removed, and from the upper side, the electromagnet 125 adsorbs and removes the metallic foreign matter E2. This makes it possible to quickly remove various foreign substances mixed with the aggregate. On the other hand, the diaphragm 121 is installed in a form surrounding a fence 121a composed of a mesh network along the upper surface. This serves to allow magnetic force by the electromagnet 125 because it is the blowing pressure by the blower 123 while blocking the aggregate (S) from being separated from the vibration plate 121.

The particle size separator 130 serves to separate the pulverized aggregate by particle size. To this end, the separator 130 for each particle size is provided with a plurality of meshes made of pores of different sizes or a bar for each particle size to filter and separate the pulverized aggregate for each particle size.

The cleaning device 140a cleans the natural stone aggregate particles using high-quality oxygen water manufactured by the oxygen dissolver 141 prior to plasma treatment of the natural stone aggregate. When high-quality oxygen water is used, various bacteria remaining on the surface of natural stone aggregate particles can be quickly sterilized.

The plasma treatment apparatus 140b serves to perform plasma treatment on the surface of the cleaned aggregate before mixing the aggregate and the pigment in order to increase the coloring efficiency of the pigment with respect to the aggregate. To this end, the atmospheric pressure plasma processing device 140b may be simply installed on a line without the need to implement it in a vacuum device or a large-sized mechanical device. When such a plasma processing apparatus 140b is provided, micro-craters are formed on the surface of the aggregate, thereby increasing a root mean square (RMS) roughness value. This provides conditions in which the binding of the pigment component to the aggregate surface can be easily achieved.

The first stirrer 150a serves to mix and sufficiently stir the plasma-treated aggregate and pigment. This allows the pigment to be uniformly dispersed and applied on the surface of the aggregate in a sufficient amount.

The coloring furnace 160a serves to stably color the pigment in the aggregate by heating the aggregate and the pigment stirred in the first stirrer 150a in the coloring furnace 160a. The heating temperature made in the coloring furnace 160a is suitable in a range of 200°C or higher to 1000°C.

The second stirrer 150b serves to coat the surface by mixing and stirring a vegetable resin, a UV stabilizer, and a curing accelerator in the colored aggregate.

The heating furnace 160b serves to impregnate the aggregate with a surface-coated vegetable resin, UV stabilizer, and curing accelerator into the heating furnace 160b. Although the heating furnace 160b is provided with the same type as the coloring furnace 160a, it is preferable to provide each of the heating furnaces 160b because they handle different materials.

The cooling dryer 170 serves to cool and dry the aggregate impregnated with the protective agent in the heating furnace 160b. To this end, the cooling dryer 170 passes the aggregate heated in the heating furnace 160b through the cooling dryer 170 installed long along the conveyor 190, as shown in FIG. 9. The cooling dryer 170 is composed of a box-shaped body 171 providing a passage through which a conveyor for transporting aggregate can pass, and a plurality of blowing fans 172 arranged along the conveyor in the box-shaped body 171. According to the configuration of the cooling dryer 170, it is possible to quickly cool and dry the heated aggregate.

The first phosphorescent pigment application device 180 is provided with a plurality of high-pressure sprayers capable of spraying the phosphorescent pigment at high pressure, and applies the phosphorescent pigment in an amount of 10 to 40L per ^{m 2.} At this time, the photoluminescent pigment is first applied, the photoluminescent pigment is applied second after the first applied photoluminescent pigment is fixed, and when the second applied photoluminescent pigment is fixed, the photoluminescent pigment is applied third. As a result, the thickness of the phosphorescent pigment can be secured to a certain value or more, and the period of light emission by the phosphorescent pigment can be increased, thereby enabling semi-permanent use. When the first phosphorescent pigment application device 180 is passed, it can be said that the production of the color aggregate is completed.

The third stirrer 210 mixes and stirs the color aggregate manufactured through the above facilities, a two-component polyurethane resin, and a curing accelerator. At this time, 70 to 95% by weight of the color aggregate, 4 to 30% by weight of the polyurethane resin, and 0.001 to 3% by weight of the curing accelerator are mixed. Here, the polyurethane resin mixed with the colored aggregate completely replaces the cement and serves to bind the colored aggregate with high strength, and the curing accelerator accelerates the curing of the polyurethane resin to shorten the curing time.

The first molding machine 220 pressurizes the mixture of the color aggregate, polyurethane resin, and curing accelerator stirred in the third agitator 210 into the module body 310. The first molding machine 220 is pre-sprayed with a moisture-type release agent before pressing, so as to prevent a problem in which the polyurethane resin or color aggregate is adhered.

The first curing machine 230 gradually passes the module main body 310 removed from the first molding machine 220 through the first curing machine 230 installed along the conveyor, which is the transfer device 190, or for a sufficient time. It plays a role of curing while storing. The first curing machine 230 includes a plurality of cooling fans to adjust the curing speed of the module main body 310 after the molding has been completed.

The controller plays a role of overall controlling the processing and transfer process of the aggregate in connection with the various devices mentioned above, including the transfer device 190.

The fourth stirrer 240 serves to uniformly mix the components of the mortar, and in particular, the short fiber PE ply yarns 351 and 352 are uniformly dispersed in the mortar.

The second molding machine 250 pressurizes the mortar stirred in the fourth stirrer 240 with the module reinforcement part 320.

The second curing machine 260 gradually passes the module reinforcement part 320 removed from the second molding machine 250 through the second curing machine 260 installed along the conveyor, which is the transfer device 190, or for a sufficient time. It plays a role of curing while storing. The second curing machine 260 includes a plurality of cooling fans to adjust the curing speed of the module reinforcement part 320 that has been molded.

The second phosphorescent pigment coating device 270, like the first phosphorescent pigment coating device 180, has a plurality of high-pressure sprayers capable of spraying the phosphorescent pigment at high pressure, and the phosphorescent pigment is 10 to 10 per ^{m 2} Apply in an amount of 40L. At this time, the photoluminescent pigment is first applied, the photoluminescent pigment is applied second after the first applied photoluminescent pigment is fixed, and when the second applied photoluminescent pigment is fixed, the photoluminescent pigment is applied third. As a result, the thickness of the phosphorescent pigment can be secured to a certain value or more, and the period of light emission by the phosphorescent pigment can be increased, thereby enabling semi-permanent use. When the second phosphorescent pigment application device 170 is passed, it can be said that the production of the color aggregate is completed. When the second phosphorescent pigment applying device 270 is passed, it can be said that the manufacturing of the module reinforcement part 320 is completed.
