Chip for filling at artificial turf planting place}

The present invention relates to a chip for filling artificial turf planting, and more specifically, to obtain a chip having a particle size of 0.5 ~ 1.0㎜ by pulverizing the polyurethane rubber from the collected waste materials collected and then manufactured 30 to 90% by weight of the prepared polyurethane rubber chip and 10 to 70% by weight of ocher powder having a particle size of 0.1 to 1.0 mm are added, and 5 to 15 parts by weight of polyurethane resin solution is added to 100 parts by weight of the mixture. After mixing, it is made of polygonal chips, passed through a 2.0 mm sieve and a 0.8 mm sieve to obtain a polyurethane rubber chip having a size of 0.8 mm to 2.0 mm, and then used for filling artificial turf. It does not generate the characteristic smell of rubber and blocks the absorption of sunlight so that the temperature of the stadium is not raised above room temperature, making breathing easier during exercise. And hurt like wearing no position relates to artificial grass planting processing chip for filling to achieve the effect of providing a comfortable workout environment.

Artificial turf is one of the specially used landscaping materials, and is a substitute for artificially made grass in the form of grass. Since it was first manufactured in the United States in 1956, it has been used mainly in sports grounds. It can be used in indoor gardens where turf growth is not possible, or in outdoor areas facing the north side of high-rise buildings with very limited sunshine hours. The main materials are polyvinylidene chloride, polyethylene, polypropylene and nylon.

Artificial turf can always maintain greenness and is easy to manage after construction without being restricted by environmental conditions. On the other hand, there is no seasonal feeling and texture is slightly lower than grass, and it has a disadvantage of fading over time. Since it was first adopted at the Astrodome indoor baseball field in Texas in 1966, it has been in the spotlight as an all-weather facility including a soccer field, field hockey field, various interior and leisure facilities.

In general, the conventional method of planting artificial grass is to bury the drain pipe at a depth of about 60cm underground, put rubble into it and compact it. Then, put sand layer on the rubble and compact it. It is constructed in such a way that a curing layer is formed, an adhesive layer is applied to the surface of the curing layer, and an artificial turf layer is adhesively disposed thereon. In addition, a non-woven fabric may be provided on the sand layer, or a shock absorbing layer such as a foam rubber mat or a rubber mat may be installed on the upper part of the hardener layer, and a water field using artificial grass liquor having a length of 12 to 13 mm and sprayed with water (water field) Fields and artificial turf liquors having a length of 25 mm are divided into sand field stadiums using silica sand and rubber chips filled between artificial turf.

In particular, when artificial turf grounds are constructed in the form of sandfields, they are first filled with silica sand as a filler and secondly filled with EPDM (Ethylene Propylene Diene Monomer) chips, waste tire chips or recycled rubber chips, or general rubber chips. .

Among the fillers described above, EPDM chips have a problem in that the manufacturing process of the price is opaque, harmful substances are detected, and they cannot be recycled when damaged. The application is rarely made.

In addition, waste tire chips, recycled rubber chips, or general rubber chips not only interfere with movement due to the characteristic odor of rubber, but also have a black color, so it absorbs sunlight and increases the temperature of the stadium. It is high because it is difficult to breathe at the time of exercise, such as restrictions on the exercise, and fall falls, such as abrasions or burns caused by the filler material, there is a disadvantage that does not provide a comfortable exercise environment.

Accordingly, an object of the present invention is to prevent the unique smell of rubber and to block the absorption of sunlight so that the temperature of the ballpark does not rise above room temperature, so that breathing is not easy during exercise, and if you fall, you will get abrasions or burns. It is to provide a chip for filling artificial turf planting that can not be hurt, such as to wear, and to obtain the effect of providing a comfortable exercise environment.

It is another object of the present invention to provide a method for easily manufacturing a chip for filling artificial turf.

In order to achieve the above objects as well as other objects that are easily expressed in the present invention, the polyurethane rubber is selected from the collected waste materials and pulverized to obtain a chip having a particle size of 0.5 to 1.0 mm. 30 to 90% by weight of the prepared polyurethane rubber chip and 10 to 70% by weight of ocher powder having a particle size of 0.1 to 1.0 mm are added, and 5 to 15 parts by weight of polyurethane resin solution is added to 100 parts by weight of the mixture. After mixing, it is made of polygonal chips and passed through a sieve of 2.0 mm and 0.8 mm to obtain a polyurethane rubber chip having a size of 0.8 mm to 2.0 mm, which is then used for filling artificial turf. It does not generate odor and blocks the absorption of sunlight so that the temperature of the stadium is not raised above room temperature, making breathing easier during exercise. Not hurt the mouth, such as an award or burns, and could be obtained the effect of providing a comfortable workout environment.

The artificial turf planting filling chip according to the present invention does not generate a characteristic odor of rubber and blocks the absorption of solar light so that the temperature of the stadium is not raised above room temperature so that breathing is not easy during exercise, even if it falls down. No scratches, burns, and other injuries were provided, and a comfortable exercise environment was obtained.

The artificial turf planting filling chip according to the present invention is to select the polyurethane rubber from the collected waste material and pulverized it to obtain a chip (chip) having a particle size of 0.5 ~ 1.0㎜, manufactured polyurethane rubber chip 30 ~ 90 weight% and 10 to 70 weight% of ocher powder having a particle size of 0.1 to 1.0 mm are mixed, and 5 to 15 weight parts of polyurethane resin solution is added to 100 weight parts of the mixture and mixed again, followed by polygonal chips. And a size of 0.8 mm to 2.0 mm through a 2.0 mm sieve and a 0.8 mm sieve.

Polyurethane rubber used in the present invention is preferably used to be collected separately for recycling, but not limited to all polyurethane rubber can be used.

Polyurethane rubber is manufactured and used as a chip (chip) having a particle size of 0.5 ~ 1.0mm by using a grinding device and a sorting device commonly used in the art.

If the particle size of the polyurethane rubber chip is less than 0.5 mm, the final size of the chip is small, so that it is not economical because a small amount of the chip of the desired size can be obtained. The disadvantage is that it becomes too large to obtain a chip of a desired size.

In addition, high quality ocher is prepared into a powder having a particle size of 0.1 to 1.0 mm by using a grinding device and a sorting device commonly used in the art.

If the particle size of the ocher powder is less than 0.1 mm, the final particle size of the chip is small, so that the amount of the chip of the desired size is small, which is not economical, and it is not easy to combine the ocher powder and the polyurethane rubber chip added. If it exceeds 1.0 mm, the chip size is too large to produce a chip having a desired size.

Then, 30 to 90% by weight of the polyurethane rubber chip and 10 to 70% by weight of the ocher powder were mixed, and 5 to 15 parts by weight of the polyurethane resin solution was added to 100 parts by weight of the mixture and mixed again. It is made of a chip having.

If the amount of polyurethane rubber chips is less than 30% by weight or the amount of clay powder is more than 70% by weight, the strength of the finished product is so weak that when it is stepped after filling, it is broken or made into chips of 0.8mm to 2.0mm in size. There is a problem that it is not easy to do, and when the amount of the polyurethane rubber chip exceeds 90% by weight or the amount of the ocher powder is less than 10% by weight there is a disadvantage that the desired effect can not be obtained in the present invention.

The polyurethane resin solution used in the present invention serves to adhere the polyurethane rubber chip and the ocher powder. In the technical field to which the present invention belongs, the polyurethane resin solution commonly used for the adhesive may be used.

In addition, when the amount of the polyurethane resin solution used in the present invention is less than 5% by weight, the adhesion of the polyurethane rubber chip and the ocher powder is not easy, and there is a disadvantage in that it is not manufactured with a chip having a size of 0.8 mm to 2.0 mm. When it exceeds the weight%, there is a problem in that the adhesion of the polyurethane rubber chip and the ocher powder is so strong that it is not easy to manufacture a polygonal chip.

After the chip is made of polygonal chips, only a polyurethane rubber chip having a size of 0.8 mm to 2.0 mm is selected and used through a 2.0 mm sieve and a 0.8 mm sieve.

When the particle size of the finished product is less than 0.8mm, the efficacy as a filler decreases, and the buffering effect is not expressed. Therefore, the movement is liable to be damaged by joints such as knees or the surface is slippery, and the movement is weak, and the supporting force is weak, so that the momentary operation is not easy. If there is a disadvantage, if it exceeds 2.0 mm, the exercise person is susceptible to skin damage and falls, the filling effect is also reduced.

Polyurethane rubber chip for artificial turf planting material filling according to the present invention prepared as described above is because the loess is mixed with far-infrared radiation from the ocher not only shows a useful effect on the human body, but also actually planted grass on the land, such as You get a feeling and you can create a comfortable exercise environment.

In particular, the far-infrared ray emission amount (40 ℃) of the artificial turf plant filling polyurethane rubber chip according to the present invention was measured by the method of KICM-FIR-1005 by the Korea Institute of Construction Materials, the emissivity (5 ~ 20㎛) Was 0.903 and the radiant energy (W / m 2) was 3.64 × 10 ² .

In addition, as a result of testing the detection of components harmful to the human body by requesting the Korea Testing Institute, it was confirmed that it is safe. That is, as a result of quantitative analysis of Pb and Cd by the method of ISO 6101-1: 1997 (ICP), Pb and Cd were not detected, and Hg was analyzed by the method of US EPA Method 3052: 1996 (AAS), but not detected.
