Description

A filling layer and an artificial turf containing environment friendly filling materials}

The present invention relates to a filler for artificial turf, and more particularly, to a filler layer and artificial turf using an environmentally friendly filler for artificial turf that prevents radiant heat and provides heavy metal adsorption and loss prevention functions using environmentally friendly natural materials. .

In general, artificial turf is mainly constructed in areas where natural grass is difficult to grow, such as dome stadiums, buildings, and schools, or where management is difficult. Artificial turf has a higher initial cost than natural grass, but is not influenced by weather and season, and its use is continuously expanding due to the convenience of maintenance.

Artificial turf uses a variety of fillers when installed to give a similar effect and feel to natural grass. As filler, synthetic rubber such as SBR (Stylene Butadiene Rubber) rubber chip and EPDM (Ethylene Propylene Diene Monomer) rubber chip are mainly used. Therefore, the construction cost of artificial turf construction increases, and is difficult to maintain due to loss and damage due to external influences such as weather. In addition, in children with weak skin due to the surface temperature increase due to radiant heat, there is a risk of burns and odors and harmful components peculiar to rubber are generated.

In addition, due to the nature of synthetic rubber, excessive activity in artificial turf for a long time due to excessive elasticity, can increase the fatigue on the body, can cause respiratory and skin diseases such as scattering phenomenon.

The present invention is to solve the problems described above, by using a mixture of natural materials such as chaff, 칡, ocher and SEBS (Styrene Ethlene Butylene Styrene) rubber chip during the construction of artificial turf, harmless to human body artificial turf And while satisfying the function of the natural grass and at the same time, the object of the present invention is to provide a filling layer and artificial grass using environmentally friendly filler for artificial grass that can lower the construction cost.

Furthermore, an object of the present invention is to minimize the loss of the filler for artificial turf generated due to a large amount of rainwater or classmates, and to suppress the sudden temperature rise of the surface temperature due to easy maintenance and radiant heat of the artificial turf.

Furthermore, the present invention minimizes the body's fatigue caused by excessive activity in artificial turf for a long time due to excessive elasticity of the synthetic rubber filler, and suppresses the scattering phenomenon of harmful components (a phenomenon in which fine particles or active ingredients move to a place other than the target). To prevent skin and respiratory diseases.

Furthermore, the present invention uses a natural filler consisting of rice husk, ground crushed ground, ocher, to be generated from the rubber-based filler It aims to remove the odor peculiar to synthetic rubber and to provide a comfortable environment in the space where artificial turf is constructed.

According to an embodiment for achieving the above object, artificial turf, chaff, and chaff tangled with the chaff to prevent the chaff from floating on the surface during rain or classmates, and the chaff and the chaff ground grinding Pressing water at its own load, the lower layer as the rubber-based filler when filling the artificial grass filler consisting of a natural filler including the clay to stabilize the chaff and the ground crushed ground and a rubber-based filler using a rubber-like synthetic resin To achieve, characterized in that forming the upper layer with the natural filler.

By forming the filling layer with natural material fillers such as rice hulls, 칡 by-products, ocher and elastic rubber-based fillers on the artificial turf, it is possible to prevent the generation of harmful elements such as heavy metals or carcinogens.

Furthermore, due to the natural filler in the upper layer to minimize the loss of the filler when a large amount of rain or classmates, it is possible to prevent damage to the filler for artificial grass by water. In addition, since there is a sudden increase in surface temperature due to radiant heat, there is no risk of dig phenomenon and burn of the high temperature summer filler.

Furthermore, the natural filler reduces the excessive elastic force of synthetic rubber fillers such as SBR (Stylene Butadiene Rubber) rubber chips and EPDM (Ethylene Propylene Diene Monomer) rubber chips.

Furthermore, since the odor generated by the rubber-based fillers is suppressed and no scattering occurs, it can be installed indoors in public places with a large number of households and moving personnel. Therefore, while preventing the influx of harmful components into the human body through the respiratory system, it provides a comfortable environment.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily reproduce the present invention.

1 is a cross-sectional view showing the structure of a general artificial turf. In general, artificial grass, which is mainly constructed in areas where natural grass is difficult to grow, such as a dome stadium, a building, or a school, is difficult to be formed of a combination of a plurality of artificial grass unit units 100. As shown, the artificial turf unit unit 100 includes a support plate 101, and a plurality of artificial grass 102 coupled to one surface of the support plate 101.

In one embodiment, the support plate portion 101 is made of a grass plate 101a and a rubber plate 101b, the plurality of artificial grass 102 is a portion that is coupled, the upper surface of the grass plate 101a is a plurality of The artificial turf 102 has a plurality of insertion grooves to be inserted. The artificial turf 102 is inserted into the plurality of insertion grooves, respectively, and the artificial turf 102 can be easily fixed through various methods such as a bonding process on the surface of the turf board 101a.

In one embodiment, the artificial turf 102 has an insertion member (not shown) at the bottom, and is similar to natural grass in shape and color. It is mainly made of various synthetic resins such as polyester (PE). In addition, the filler is filled in the gap between the artificial turf 102 and the support plate 101, thereby increasing the bearing capacity of the artificial turf 102 and satisfying the visual and functional effects.

Figure 2 is a cross-sectional view showing the structure and structure of the filling layer using an environmentally friendly filler according to an embodiment of the present invention. As shown, the filling layer composition using eco-friendly filler is composed of rice bran, chaff, which is tangled with rice bran, and crushed ground flakes, chaff and ground crushed ground which prevent the chaff from floating on the surface during rain or rain. For artificial turf made of a natural filler (200a) including the ocher to serve to press and fix, and a rubber-based filler (b) consisting of a plurality of spherical materials made of a material having elasticity using a synthetic resin of rubber properties When filling the filler 200 forms a lower layer of the rubber-based filler (200b), the upper layer of the natural filler (200a), and includes an antimicrobial material for preventing corruption. In this case, the packed layer structure is characterized in that the ratio of 50:50.

In one embodiment, the chaff contained in the natural filler (200a) is 40 to 80% by weight, 칡 ground grinding is 10 to 30% by weight, the present invention is not limited to this, the ratio of the weight% according to the environment Can be different. The chaff has a high water absorption amount and a high absorption rate, absorbs a part of the water flowing into the artificial turf 102, and smoothly drains the water, thereby eliminating the water retention phenomenon. 분쇄 The ground pulverized product is composed of a large amount of fiber and has a high water absorption rate, and has a property of being entangled with the water-absorbed chaff, thus preventing the chaff from flying or the chaff rising to the surface of the water. Ocher is included in a proportion of 10 to 70% by weight, and may vary in proportion by weight depending on the environment. In addition, the ocher absorbs water and coagulates with the classmates or rainwater when chaff, 칡 waste crushed with each other and at the same time has a natural weight to press the natural filler (200a). In addition, it has excellent humidity control ability, excellent antibacterial effect, removes bad smell and emits a large amount of far infrared rays.

Accordingly, the upper and lower layers of the filler 200 are composed of a natural filler 200a and a rubber-based filler 200b, and the structure of the filler layer is 50:50, so that a large amount of classmates or water may be used. It is possible to minimize the loss of the filler 200 to the sewer, and to solve the water pooling phenomenon on the artificial turf (102). It also prevents harmful substances from coming into contact with the respiratory system or skin due to scattering. Furthermore, the present invention is not limited thereto, and the ratio of forming the structure of the filling layer may be varied according to the construction place of the artificial turf or the external environment.

Since the natural filler 200a maintains the proper temperature of the artificial turf 102 continuously, the temperature rise due to radiant heat is suppressed, so that the risk of burn is very low even if the activity or slips on the artificial turf 102 for a long time. Furthermore, by adding an antibacterial substance to the filler 200 to prevent corruption, it is possible to suppress the occurrence of mold and maintain microbial stability.

In one embodiment, the rubber-based filler (200b) is a SEBS (Styrene Ethlene Butylene Styrene) rubber chip, a chip formed by injection molding a synthetic resin of rubber properties. SEBS is free of dust and has a significantly low carcinogen and heavy metal contamination. The present invention is not limited to SEBS, and rubber chips of various shapes and properties, such as EPDM and urethane chips, may be used.

According to an embodiment of the present disclosure, the ratio of the rubber-based filler 200b is 3.5% by weight based on 1 wt% of the natural filler 200a and the rubber-based filler 200b described above. It is characterized by forming a packed layer structure at a ratio of: 50. It can be seen that this packed bed has an excellent effect of preventing the sudden rise in temperature as the graph explains in the temperature change test for each packed bed.

Figure 3 is a graph showing the temperature change test results of the packed bed according to an embodiment of the present invention. As a result of testing the temperature change for each packed layer as shown, the temperature change of the rubber-based filling layer, the temperature change of the natural filling layer and the temperature change of the filling layer according to the present invention was tested.

Test method,

A 200 W bulb is used as the heat source, the filling layer is located 8 cm below the heat source, and the temperature sensor is located 2 cm below the filling layer.

As a result of the test, the maximum temperature of each filling layer heated for about 90 minutes by the heat source is about 100 ° C for the rubber-based filling layer and about 37 ° C for the natural filling layer, while the filling layer according to the present invention is about 39 ° C. This has a temperature difference of about 61 ° C. with the rubber-based filling layer, demonstrating the effect of suppressing a sudden temperature rise. This test result has the same result when the proportion of rubber-based filler is 3.5 wt% or less under the same conditions, and the effect of temperature rise suppression can be confirmed even when 3 wt%.

4 is a chart showing the results of the resilience test of the packed layer according to an embodiment of the present invention. As shown in the result of testing the resilience, side elasticity for each filling layer, the recovery rate of the natural filling layer, SEBS filling layer, EPDM filling layer and the filling layer according to the present invention was measured.

Test method,

The volume of each packed bed is equal to 30 ml, the same pressure is applied to each packed bed, the volume is measured, and the volume after the pressure is released.

As a result of the test, the filling layer composed of the natural filling material has 56% restoring force, while the SEBS filling layer, which is a rubber-based filling layer, has 93% restoring force, and the EPDM filling layer has 75% restoring force, while in one embodiment of the present invention, The filling layer by the filling material and the rubber-based filling material has a recovery ratio of 83% when the volume ratio forms the filling layer structure at a ratio of 1: 1 and 50:50. This is to reduce the excessive elastic force of the rubber-based filling layer to the low elastic force of the filling layer composed only of natural materials, thereby maintaining the elastic force close to the natural grass. Therefore, even if you exercise hard on the artificial turf for a long time, the accumulated fatigue of the body including the knee and waist can be significantly lowered.

In addition, under the same test conditions, 67% when the volume ratio of the natural and SEBS fillers is 2: 1, 65% when the volume ratio of the natural and EPDM fillers is 1: 1, and 65% of the natural and EPDM fillers It has a recovery rate of 69% when the volume ratio is 2: 1. This figure is lower than the average recovery rate of 80%, which can be judged to be generally lower than the elastic force felt by natural grass.

Through the results of the temperature change test and the resilience test of the packed bed, when the packed bed is composed of 1% by weight of the natural filler, the rubber-based filler is in the range of 3 to 3.5% by weight, and each filler is 50: When the filling layer structure is formed at a ratio of 50, it can be seen that the most ideal filling layer is formed. That is, the temperature range of the filling layer does not show a sharp difference from the ground temperature range of the natural grass, and has an elastic range close to the natural grass. Thus, users can have a feel of natural turf on artificial turf.
