Description

The manufacturing method of color elastic pavement material using cork chip and paving method of color elastic pavement material}

The present invention relates to a method of manufacturing a color elastic packaging material using cork chips and a method of installing a color elastic packaging material, and more particularly, a method of manufacturing a color elastic packaging material having a beautiful appearance and excellent durability by coating various colors on cork chips It relates to a method of laying elastic packaging material.

In general, trails and bicycle paths are designed to improve the convenience and health of residents, and the trails and bicycle paths are provided with boundary stones at a certain width on both sides between landscapes and trees, and the trails expose natural soil and When constructing a bicycle road or artificially constructing it, most of them are formed by placing a speech on the ground using a sidewalk block made of cement or pouring it on the ground using concrete or asphalt concrete.

Conventional trails and bicycle paths that are exposed to natural soil have defects in that the trails are easily lost due to the soil being washed in rain in rainy weather, and maintenance is frequent.The trails and bicycle paths constructed with sidewalk blocks, concrete and asphalt concrete, etc. Although it has the advantage of excellent durability and easy construction, there is a problem in that a large injury occurs to the body even when the user falls due to negligence or the user's light collision.

In order to solve this problem, a pavement material having a certain length and width is formed by mixing rubber chips and silica sand and adhesive obtained by grinding waste tires into a certain size at a certain ratio, and then applying the adhesive to the asphalt or concrete paved surface. In addition, there is a problem in that the molded packaging material is double-packed to promote the safety of users, but there is a problem in that dust or smell is severely generated from rubber chips, and harmful substances are emitted from waste tires. In addition, some products contain heavy metals, which causes environmental pollution.

Accordingly, in recent years, there is a trend that many eco-friendly paving materials capable of eco-friendly road pavement while having excellent elasticity and permeability or drainage induction performance using cork crushed material are widely used. At this time, if pure cork chips are crushed and used directly for road pavement, there is a problem that the strength of the cork chip itself is weak, and the bonding strength between the cork chip and the binder decreases, color change, and antibacterial properties are reduced due to the effects of ultraviolet rays and seasonal changes. Because durability is reduced due to various problems, the cork chip elastic packaging material processed through various surface processing steps in advance is used for road pavement.

Korean Patent Registration No. 10-2063965 discloses an elastic packaging material composition and an elastic packaging construction method using cork chips.

Since the elastic packaging material composition coats the surface by applying a coating solution to the surface of the cork, the strength of the cork chip can be relatively increased, but there is a problem that the effect of improving the strength with only one coating is insignificant. In addition, the elastic packaging material composition has a problem in that it cannot implement various colors.

Hereinafter, it looks at each step in detail.

1. Screening step

The cork is finely crushed to select the appropriate sized cork chips.

Cork (cork) can be used that is collected from oyster oak or oak. In addition, it is of course possible to use the waste generated in the cork stopper processing process for cork. In addition, it is possible to recycle the cork used for existing elastic packaging or collect and use the cork from oak waste used for mushroom cultivation.

Cork has excellent properties in terms of high elasticity, low thermal conductivity, sound insulation, light weight, and shock absorption. In addition, cork can reduce the heat island phenomenon due to low radiant heat and create a pleasant environment without the smell of rubber.

Small pieces of cork can be obtained by crushing the cork. For cork chips, only cork chips of 2 to 15 mm in size are selected through a sorting process and used as a material for elastic packaging.

An example of a sorter for sorting cork chips is shown in FIG. 5.

5, the separator supplies air to the supply hopper 50 into which the pulverized crack chips are inserted, the cyclone 53 connected to the supply hopper 50 and the transfer pipe 51, and the transfer pipe 51 Thus, a blower (not shown) for transferring the cork chips stored in the supply hopper 50 to the cyclone 53, and a sieve unit 55 for sorting the cork chips discharged from the lower portion of the cyclone 53 by size are provided. do.

The cork chips pulverized and discharged in the crusher are introduced into the supply hopper 50. A transfer pipe 51 is connected to the outlet of the supply hopper 50. The transfer pipe 51 is installed to connect the outlet of the supply hopper 50 and the cyclone 53. Although not shown, a blower is connected to one side of the transfer pipe 51 to supply high-pressure air to the transfer pipe 50. Cork chips injected into the supply hopper 50 by the high-pressure air supplied to the transfer pipe 51 are fed into the air and introduced into the upper portion of the cyclone 53.

Cork chips introduced into the inside of the cyclone 53 rotate within the cyclone 53 together with air. The cork chip descends while colliding with the inner surface of the cyclone 53 while turning, and air is discharged through the exhaust pipe 54 connected to the upper portion of the cyclone 53. Cork chips discharged through the lower portion of the cyclone 53 pass through the retention chamber 57 and flow into the sieve unit 55.

In the sieve unit 55, a plurality of sieves 58 are arranged vertically. Each sieve 58 is installed obliquely. The eyes of the lower one have smaller eyes than the upper one. The cork chips filtered by each sieve 58 are discharged to the outside through the chute 59 provided on the side.

Cork chips having a size of 5 to 15 mm among cork chips selected by size through the sieve unit 55 are used for the first coating.

On the other hand, cork chips can be carbonized and used. For example, the selected cork chips may be put into a furnace and carbonized by heating at 400 to 600° C. for 2 to 10 hours in an oxygen-free atmosphere. The carbonized cork chip thus obtained has a large surface area while undergoing thermal decomposition of organic matter, and has an excellent adsorption ability and antibacterial effect due to increased surface charge. In addition, the carbonized cork chip may have various colors depending on the degree of carbonization. In addition, carbonized cork chips have the advantage of suppressing discoloration compared to non-carbonized cork chips. In addition, since the carbonized cork chip has numerous pores formed on its surface, it is possible to improve the bonding strength with the coating layer.

2. 1st coating step

In the first coating step, a first coating agent is applied to the cork chip to form a first coating layer on the cork chip. The cork chip on which the first coating layer is formed is referred to as the first coating cork chip.

A water-soluble binder may be used as the first coating agent. A water-soluble acrylic resin can be used as such a water-soluble binder. The water-soluble acrylic resin can easily penetrate from the surface of the cork chip to the inside, thereby increasing the bonding strength between the cork chip and the first coating layer.

2. Second coating step

After the first coating layer is cured, a second coating agent of the first coating cork chip is applied to form a second coating layer outside the first coating layer. The cork chip on which the second coating layer is formed is referred to as a second coating cork chip.

As the second coating agent, a composition in which a dye and a binder are mixed may be used. For example, 10 to 40 parts by weight of a dye may be mixed with respect to 100 parts by weight of a binder to obtain a second coating agent.

As the binder, a conventional polymer binder such as an epoxy resin or a urethane resin may be used. A two-component type may be used as such a polymeric binder. The two-component type polymer binder has a fast curing time and excellent strength of the coating layer.

The dye is for implementing color on the cork chip, and organic or inorganic dyes may be used. As for the dye, materials with various colors such as orange, red, yellow, green, blue, purple, and black are used.

3. 3rd coating step

After forming the second coating layer, before the second coating layer is cured, the photocatalyst ball is sprayed to fix the photocatalyst ball on the second coating layer.

The photocatalytic ball may be formed by coating a photocatalytic material on a spherical ceramic surface. As the ceramic, a porous material such as zeolite or pearlite may be used.

Titanium dioxide can be used as a photocatalyst. Photocatalysts are photo-activated when irradiated with ultraviolet rays to form electrons and electric fields to generate hydroxy radicals (-OH) and superoxides that have strong oxidizing power, and hydroxy radicals and superoxides prevent bacteria, viruses, and various organic compounds in the air. Oxidative decomposition. Of course, a material that is photoactivated by visible light can be used as a photocatalyst.

The photocatalyst ball sprayed on the second coating layer is attached to and fixed to the second coating layer while the second coating layer is cured.

Fig. 2 shows a cross-section of the cork chip completed until the tertiary coating. As shown in FIG. 2, a first coating layer 15 is formed on the surface of the cork chip 13, and a second coating layer 17 is formed on the surface of the second coating layer 15. In addition, a photocatalytic ball 19 is attached to the second coating layer 17.

4. Inorganic material coating step

Next, a coating inorganic material chip is obtained by applying a third coating agent to any one of the shells and minerals.

Oyster shells or cockle shells can be used as the shell. Use the shell after crushing finely. Porous rocks can be used as minerals. For example, you can use volcanic stone. The mineral is finely ground and used.

The inorganic material is applied with a third coating material to form a coating layer on the surface of the inorganic material. The third coating agent may be the same as the second coating agent described above. For example, the third coating agent may use a composition in which 10 to 40 parts by weight of a dye is mixed with respect to 100 parts by weight of a binder. It is preferable that the dye used for the third coating agent has a different color than the dye used for the second coating agent.

By forming the coating layer on the surface of the inorganic material as described above, various colors can be realized and the strength of the inorganic material can be increased.

A cross section of the coated inorganic material is shown in FIG. 2. As shown in FIG. 2, a coating layer 25 is formed on the surface of the inorganic material 23.

5. Mixing step

Next, the third coated cork chip, the coated inorganic material chip, and the binder are mixed to finally obtain a color elastic packaging material.

For example, 4 to 10 parts by weight of an inorganic coating chip and 20 to 60 parts by weight of a binder are mixed with respect to 100 parts by weight of the third coated cork chip to obtain a color elastic packaging material. A one-component or two-component urethane binder may be used as the binder.

Hereinafter, a method of installing a color elastic packaging material according to an example of the present invention will be described with reference to FIGS. 1 and 2.

First, install a reinforcing net (3) on the base layer. The base layer 1 may be formed by compacting soil. In addition, the base layer may be a concrete layer, an asphalt layer, or a permeable cone layer.

As the reinforcing net 3, a geogrid, which is a general reinforcing material for civil engineering, can be used. Geogrid is a grid-structured net made of polymer synthetic resin material.

Next, a mixture of crushed stone 7 and urethane resin is laid on the reinforcing net 3 at a predetermined thickness to form the lower layer 5.

The crushed stone 7 may be crushed to a size of about 30 to 50 mm. A two-component type urethane binder is used as a urethane resin. The mixture may be mixed with 20 to 60 parts by weight of a urethane resin based on 100 parts by weight of crushed stone. After laying the mixture to a certain thickness, the surface of the lower layer 10 is stopped. The lower layer may be formed to a thickness of 40 to 80mm.

Next, after the lower layer 5 is cured, an elastic packaging material is laid on the lower layer 5 to a predetermined thickness to form the upper layer 10. After laying the elastic packaging material to a certain thickness, the surface of the upper layer 10 is stopped, and then the upper layer 10 is cured. The upper layer may be formed to a thickness of 10 to 30 mm.

The elastic pavement constructed in this way has excellent properties in terms of high elasticity, low thermal conductivity, high shock absorption and abrasion resistance. Elastic pavement can be installed on playground tracks, trails, bike paths, playgrounds, sidewalks, sports facilities floors, and rooftops, and can be used as interior and exterior materials for buildings.

Meanwhile, another example of a photocatalytic ball sprayed on the second coated cork chip is shown in FIGS. 3 and 4.

3 and 4, the illustrated photocatalyst ball 40 includes a body 41, a reflective layer 43 formed on the surface of the body 41, and a transparent covering portion 44 formed to surround the reflective layer 43. ), a metal particle 45 buried in the transparent covering portion 44 to scatter light, a phosphor 47 attached to the surface of the transparent covering portion 44 to convert infrared light into visible light, and a transparent covering portion A photocatalyst 49 attached to the surface of 44 and activated by visible light or ultraviolet rays is provided.

The body 12 may be formed of a porous ceramic such as zeolite or pearlite.

The reflective layer 43 is formed on the surface of the body 41. The reflective layer 43 may be formed by coating with a material capable of reflecting light. The reflective layer 43 serves to reflect light that has passed through the transparent covering portion 44 to the outside of the body 41.

The transparent covering portion 44 is formed outside the reflective layer 43. The transparent covering portion 44 may be formed of a transparent synthetic resin material. Metal particles 45 are dispersed within the transparent covering portion 44.

The metal particles 45 may use any one selected from platinum and aluminum. The metal particles 45 may be formed of particles having a size of 10 to 100 nm. When light passing through the transparent covering portion 44 is incident on the surface of the metal particle 45, a small electromagnetic interference phenomenon occurs on the surface of the metal particle 45. In addition, waves are formed on the surface of the metal particles 45 due to interference, so that light can be effectively scattered.

The phosphor 47 is attached to the surface of the transparent covering portion 44. A fluorine-based phosphor capable of converting infrared light into visible light may be used as the phosphor 16. As such a phosphor, any one selected from NaYF ₄ :Nd ³⁺ , NaYF ₄ :Yb ³⁺ , and NaYF ₄ :Er ³⁺ may be used. The average particle diameter of the phosphor may be 100 to 500 nm. The fluorine-based phosphor converts infrared light having a wavelength range of about 800 nm or more into a visible light range.

Since infrared light is converted into visible light by the phosphor 47, it is possible to greatly reduce heat generation by infrared rays of sunlight. Infrared rays among sunlight are easily converted into thermal energy and are the main cause of generating heat. In the present invention, since infrared light is converted into visible light by means of a phosphor, the heat shielding effect can be improved, thereby reducing the heat island phenomenon in the city.

The photocatalyst 49 is attached to the surface of the transparent covering portion 44. Titanium dioxide can be used as the photocatalyst 49. Photocatalysts are photo-activated when irradiated with ultraviolet or visible light to form electrons and electric fields to generate hydroxy radicals (-OH) and superoxides that have strong oxidizing power, and hydroxy radicals and superoxides are used for bacteria, viruses, and various organic substances in the air. The compound is oxidatively decomposed.

In addition, it is of course possible to use a material that is photoactivated by visible light as a photocatalyst. In this case, since infrared light is converted into visible light by the phosphor, the effect of the photocatalyst can be greatly increased.

In the above, the present invention has been described with reference to an exemplary embodiment, but this is merely exemplary, and those of ordinary skill in the art will appreciate that various modifications and equivalent embodiments are possible therefrom. Therefore, the true scope of protection of the present invention should be determined only by the appended claims.
