FIG. 2B is a cross-sectional view illustrating a modified example of FIG. 2A viewed from the same direction as FIG. 2A.

As shown in the drawing, the boundary brick according to the present invention is a mixture of the landfill ash, black cement, fly ash and pigments to have a variety of colors and textures of the body (10a ~ 10h), the boundary brick body (10a ~ 10h) of The boundary brick bodies 10a to 10h along the pattern grooves 12a to 12h and the pattern grooves 12a to 12h formed in the longitudinal direction of the boundary brick bodies 10a to 10h during molding. It is integrally fixed to the glass consists of a glass reflector (13a) for reflecting light depending on whether the irradiation (照射).

The reflector 13a may be formed by mixing the glass beads of small particles and the epoxy resin in a ratio of 4: 1 to 9: 1% by weight to fill and fix the entire inside of the pattern groove 12a (Fig. 2a), or as shown in FIG. 2b, a pre-prepared epoxy resin may be applied to the surface of the pattern groove 22a, and then the glass bead 23a may be applied thinly to fix it, but any of these may be used. .

The manufacturing method for the boundary brick of the present invention configured as described above is as follows.

<Production Example>

<Step 1: Landfill processing step>

Bottom ashes of various particle sizes collected are pulverized with a roll mill of 20-50 horsepower. The reason for grinding is to crush the remaining burnt lumps contained in the landfill ash so that they burn well during the firing process. The ground landfill is again screened to form a particle size of 25-30 mesh with a sieve having 25-30 mesh. The reason for the selection is to filter out foreign substances such as stones. After sorting, the mixture is put into a kiln at 1000-1150 ° C and calcined for 8-10 hours, and then dried again for 4-5 hours to prepare a homogeneous landfill. The reason for calcining the landfill ash is to obtain excellent aggregate free of impurities by burning off the heavy metal, carbon powder and salt contained in the landfill ash.

<Step 2: Formulation Step>

20 to 50% by weight of the ground ash (Bottom Ash) and 25 to 45% by weight of fly ash (Fly Ash) processed in Step 1 are added to the prepared stirrer and mixed uniformly firstly for 2 to 4 hours. After the first mixing is completed, 25 to 35% by weight of black cement is added and the mixture is mixed again for 2 to 4 hours to obtain a blend.

In the present invention, when less than 25% by weight of black cement is used, there is a problem in molding, and when it is used in excess of 35% by weight, the boundary brick becomes too heavy.

In the present invention, when the boundary brick is formed using less than 25% by weight of fly ash and less than 20% by weight of ash ash, color saturation and texture of the boundary brick are deteriorated. In addition, when the excessive use of black cement is relatively inevitable, the recycling ratio of waste (especially landfill ash) is lowered, and thus, the cost of cost cannot be reduced.

On the contrary, when fly ash exceeds 45% by weight, the surface of the product is smooth and the texture is improved, but there is a possibility that the function of the black cement added together may be impaired, thereby decreasing the formability and strength of the product. When the amount of landfill ash added exceeds 50% by weight, it is excellent in terms of recycling, but the grain is thicker than the black cement or fly ash, resulting in a rough surface, which may weaken the texture of the product.

Landfill ash used in the present invention used an average particle diameter of 20 ~ 23㎛ generated from Boryeong thermal power plant, it is composed of the components shown in Table 1.

In particular, the landfill ash is coal ash obtained by burning anthracite coal. The anthracite is coal that is well carbonized and burns without smoke, and has a low volatile content of 3-7% and a high fixed carbon content of 85-95%. Therefore, when burning, the flame is short and there is no smoke. Non-coking does not coke. Since the ignition point is about 490 ℃, the fire does not catch well, but the fire is strong and it burns continuously while maintaining a constant temperature. It is mainly produced from the old strata of Paleozoic, and most of Korea's coal belongs to it.

Fly ash was used having an average particle diameter of 20 ~ 25㎛ generated from Boryeong thermal power plant, it is composed of the components shown in Table 1.

Black cement was used in each company's product as a finished product, and the black cement had a very similar chemical composition ratio to landfill ash and fly ash (see Table 1 below).

<Step 3: Pigment Mixing Step>

In order to give a variety of colors to the evenly blended formulations to complete the step 2, water was added with the addition of 10 to 20% by weight of the pigment (see the physical picture of Fig. 3a-3g) to the total weight of the formulation, and then again in a stirrer The pigment is aged to fix the formulation well while mixing for 2 to 4 hours. Cobalt, chromium, cadmium, and iron oxide are used as the pigment, which is one of the main components in the boundary brick of the present invention, and the pigment means a mineral that does not oxidize even at a high temperature of 1200 to 1500 ° C and maintains saturation and coloring. Such pigments mean minerals suitable for various colors. As a pigment, the same thing as the description of Table 2 below, or a mixture of two or more thereof is used. As the pigment used in the present invention, it is preferable to use a non-toxic pigment that is harmless to the human body.

In the present invention, when the pigment is less than 10% by weight, the saturation for coloring and color may be lowered, and the texture of the boundary brick may be lowered. On the contrary, when the amount of the pigment is more than 20% by weight, the saturation for the color and color is Although it can be increased, there is a problem that the half of the texture and the increase in cost due to over-coloring the primary color. Therefore, in the present invention, it is preferable to use a pigment of 10 to 20% by weight.

<Step 4: Molding Step>

The mixture added with the pigment collected in the stirrer is put into a mold of a predetermined shape and vacuum-compressed at a pressure of 20 to 50 psi to form a boundary brick molding having various colors having various moisture content of 10 ± 2% and pattern grooves of various shapes (Fig. 1A to Fig. 1). 1H).

<Step 5: Drying Step>

After completing the molding, the boundary brick molding having various colors and pattern grooves is dried for 2 to 4 hours at 100 to 150 ° C, and then naturally dried for 48 to 72 hours.

Step 6: Install glass reflector

In the pattern groove of the completely dried boundary brick molding, a glass reflector reflecting light depending on whether the light is irradiated is fixed integrally therein to obtain a final product.

The glass reflector used herein is a mixture of glass beads and an epoxy resin in a ratio of 4: 1 to 9: 1% by weight, and the glass reflector is filled and fixed in a pattern groove (see FIG. 2A) or the epoxy resin is patterned. Apply to the surface of the groove and then fix it with a thin coating of glass beads on it (see Figure 2b).

The manufactured boundary brick is used as a boundary brick of a road or a pedestrian road, and by the light reflecting function of the glass reflector for light reflection, the boundary brick serves as a guide display for a driver or pedestrian to pass safety at night.

Example 1

25% of black cement, 25% by weight of fly ash and 50% by weight of processed ash ash are mixed to form a blend, and 20% by weight of pigment is mixed with the total weight of the formulation, followed by natural aging for 50 hours, and 50psi Vacuum extrusion was carried out under pressure to form a boundary brick having a pattern groove having a moisture content of 10 ± 2%. The boundary brick molded product was dried at 150 ° C. for 20 hours for 4 hours and then naturally dried for 72 hours. In the groove, a glass reflector reflecting light depending on whether the light was irradiated was installed and fixed to the pattern groove integrally.

The glass reflector used herein was a mixture composition of glass beads and epoxy resins in a ratio of 9: 1% by weight, and was filled and fixed in a pattern groove.
