본 발명의 인조잔디용 충진재는 기본재로서 왕겨를 이용하기 때문에, 친환경 적이며 인체에 무해한 효과가 있다. 또한, 상기 왕겨의 수분 함수율이 우수하기 때문에, 사람이 상기 인조잔디 위에서 미끄러지더라도, 화상의 위험성이 크게 감소한다. 상기 왕겨는 온도의 상승성이 낮기 때문에, 여름철이나 이용시간이 많을 경우에도 인조잔디가 화상 위험성 없이 이용될 수 있다. 또한 상기 왕겨는 완충성이 매우 우수하다.Since the filler for artificial turf of the present invention uses chaff as a base material, it is eco-friendly and harmless to the human body. In addition, since the water content of the rice hull is excellent, even if a person slips on the artificial turf, the risk of burn is greatly reduced. Since the chaff has a low temperature rise, the artificial turf may be used without a risk of burn even in summer or when the usage time is long. The chaff also has excellent buffering properties.

이 뿐만 아니라, 비가오거나 다량의 물이 상기 인조잔디용 충진재에 침투시, 부유 방지재가 왕겨와 얽혀서 상기 왕겨가 물에 떠내려가는 것을 방지하기 때문에, 물에 의하여 상기 인조잔디가 손상되는 것이 방지된다.In addition, when rain or a large amount of water penetrates the artificial turf filler, the anti-floating material is intertwined with the chaff to prevent the chaff from floating in the water, thereby preventing the artificial turf from being damaged by water.

만일, 상기 인조잔디용 충진재에 황토가 포함될 경우, 곰팡이의 서식을 방지하고, 원적외선을 발생하여, 인체에 유익한 효과가 있다. 더욱이, 상기 황토는 아토피의 발생을 억제하기 때문에, 유아나 어린이들이 상기 인조잔디에서 아토피의 걱정 없이 활동할 수 있다.If the ocher is included in the artificial turf filler, it prevents mold growth and generates far infrared rays, which has a beneficial effect on the human body. Moreover, since the ocher inhibits the development of atopy, infants and children can act on the artificial turf without worrying about atopy.

도 1에 본 발명의 일 실시예에 따른 인조잔디용 충진재(이하, "충진재"라 함)가 설치된 상태를 나타내는 단면도가 도시되어 있다. 도 1을 참조하면, 인조잔디(110)는 지반(120)에 적층되며, 규사(130)가 상기 인조잔디(110) 사이에 뿌려져서 상기 인조잔디(110)가 상기 지반(120)에 고정된다. 상기 충진재(100)는 상기 인조잔디(110) 사이에 뿌려져서, 상기 인조잔디(110)의 일 부분을 제외하고는 상기 충진재(100)에 의하여 덮여진다.1 is a cross-sectional view showing a state in which the artificial turf filler (hereinafter referred to as "filler") is installed in accordance with an embodiment of the present invention. Referring to FIG. 1, the artificial turf 110 is stacked on the ground 120, and the silica sand 130 is sprayed between the artificial turf 110 so that the artificial turf 110 is fixed to the ground 120. . The filler 100 is sprinkled between the artificial turf 110 and covered by the filler 100 except for a portion of the artificial turf 110.

이하에서는, 상기 충진재(100)에 대하여 보다 상세하게 설명한다.Hereinafter, the filler 100 will be described in more detail.

상기 충진재는, 왕겨, 부유 방지재 및 보조 혼합재를 포함한다. 상기 기본재인 왕겨는 60 내지 70 중량%로 이루어진다. 상기 왕겨는 일반적인 톱밥에 비하여 물에 뜨는 성질이 작다. 특히, 본 실시예에서, 상기 왕겨는 팽연 왕겨로 형성될 수 있다. 상기 팽연 왕겨는 일반적인 왕겨보다 수분 흡수 속도 및 수분 흡수량이 다소 크다.The filler includes rice hulls, floating prevention material and auxiliary mixture. The base chaff is made of 60 to 70% by weight. The chaff has a smaller floating property than water in general. In particular, in the present embodiment, the chaff may be formed of the expanded chaff. The swollen rice husk has a somewhat higher water absorption rate and water absorption than a general rice husk.

상기 왕겨는 상기 인조 잔디로부터 침투된 수분의 일부를 흡수한다. 따라서, 상기 왕겨의 중량이 증가하기 때문에, 상기 왕겨가 물에 떠서 하수구 등으로 이동되는 문제점이 감소된다.The rice hull absorbs some of the moisture penetrated from the artificial turf. Therefore, since the weight of the chaff increases, the problem that the chaff floats in water and moves to the sewer or the like is reduced.

상기 왕겨는 상기 인조 잔디로부터 침투된 수분을 흡수할 뿐만 아니라, 배수를 잘하여, 상기 인조 잔디 위로 물이 고이는 것을 방지해 준다. 상기와 같이, 왕겨가 물에 뜨는 것을 방지하고, 배수를 용이하게 하기 위하여, 상기 왕겨의 낱알 크기는 1 내지 4 ㎜이며, 바람직하게는 2 내지 3 ㎜이다.The chaff not only absorbs the moisture penetrated from the artificial turf, but also drains well to prevent water accumulation on the artificial turf. As described above, in order to prevent the chaff from floating in the water and to facilitate drainage, the grain size of the chaff is 1 to 4 mm, preferably 2 to 3 mm.

상기 왕겨는 완충성이 매우 크다. 따라서, 상기 인조 잔디 위에서 사람이 넘어질 때, 상기 사람이 인조 잔디와 충돌하는 힘을 완충하여, 상기 사람이 다치는 것을 방지해 준다.The chaff is very buffering. Thus, when a person falls on the artificial turf, the force that the person collides with the artificial turf buffers the force, thereby preventing the person from being injured.

또한, 상기 왕겨는 원적외선을 방사하는 것으로 알려져 있다. 특히, 상기 인조잔디가 햇볕이 좋은 공간에 설치되는 것을 감안하면, 여름철에 원적외선 발생량은 더욱 증가한다.The chaff is also known to emit far infrared rays. In particular, considering that the artificial turf is installed in a sunny space, the far-infrared ray generation amount increases in summer.

상기 왕겨는 불이 붙는 속도가 느리므로, 화재 발생시 피해가 최소화될 수 있다. 또한, 상기 왕겨는 잘 썩지 않는 성질을 가지기 때문에, 장시간 이용되어도 부패 가능성이 매우 낮다.Since the chaff is slow to catch fire, damage can be minimized in the event of a fire. In addition, since the chaff has a property of not easily decaying, the possibility of decay is very low even when used for a long time.

상기 왕겨는 인체에 무해하고 친환경적인 천연재료로서, 폐기 시 비료로 이용될 수 있을 뿐만 아니라, 소각에 의하여 쉽게 제거될 수 있다. 상기 왕겨는 제2의 산업 폐기물을 생성하지 않고, 가공 시 공해가 발생하지 않고, 탄소가 발생하지 않아서, 환경부담금의 문제가 원천적으로 없다.The chaff is a natural material that is harmless to humans and environmentally friendly, and can be used as a fertilizer when disposed of, as well as easily removed by incineration. The chaff does not produce a second industrial waste, no pollution during processing, no carbon generated, there is no problem of environmental burden.

전술한 바와 같이, 상기 왕겨의 함수율이 높을 뿐만 아니라, 상기 왕겨는 단열 성능이 매우 우수하다. 따라서, 상기 인조잔디의 온도가 낮게 유지될 수 있어서, 이용자가 미끄러지더라도 화상 가능성이 크게 감소된다.As described above, not only the water content of the rice hull is high, but the rice hull has a very good thermal insulation performance. Therefore, the temperature of the artificial turf can be kept low, so that the possibility of burns is greatly reduced even if the user slips.

상기 부유 방지재는, 우천 시 또는 다량의 물이 상기 인조잔디용 충진재에 침투 시, 상기 왕겨와 얽혀서 상기 왕겨가 물에 떠내려가는 것을 방지한다. 상기 부유 방지재는, 칡 찌꺼기 분쇄물 15 내지 25 중량%로 이루어진다. 상기 칡 찌꺼기 분쇄물은, 칡뿌리로부터 칡즙이 제거된 후, 남겨지는 찌꺼기를 분쇄하여 제조된다.The anti-floating material prevents the chaff from being floated in the water when it is rainy or when a large amount of water penetrates into the artificial turf filler. The anti-floating member is made of 15 to 25% by weight of ground waste ground. The ground debris is prepared by grinding the remaining debris after the debris is removed from the root.

상기 칡 찌꺼기 분쇄물은 수분이 대부분 제거된 상태이며, 상기 칡 찌꺼기 분쇄물에는 섬유질이 많이 남아 있다. 상기 칡 찌꺼기의 섬유질에 의하여, 상기 칡 찌꺼기 분쇄물이 상기 왕겨와 잘 엉겨 붙기 때문에, 상기 왕겨가 날리거나 물에 떠내려가는 것을 방지한다. 또한, 상기 칡 찌꺼기 분쇄물은 수분 흡수율이 높기 때문에, 수분을 흡수하면 하중이 커져서 상기 왕겨가 물 위로 뜨는 것을 억제해 준다.The waste ground powder is in a state where most of the water is removed, and the fiber remains largely in the ground waste ground product. The fibrous waste fiber prevents the chaff from being blown off or floated in water, because the ground meal is entangled with the chaff. In addition, since the waste ground crushed product has a high water absorption rate, absorbing moisture increases the load and suppresses the chaff from floating on the water.

또한, 비가 오지 않을 경우, 상기 칡 찌꺼기의 완충성이 매우 우수하기 때문 에, 상기 왕겨와 더불어 상기 인조 잔디의 완충성을 향상시킨다. 상기 칡 찌꺼기 분쇄물의 길이는 대략 1 내지 4 ㎜이며, 바람직하게는 2 내지 3 ㎜이다.In addition, when there is no rain, because the buffering properties of the waste is very excellent, along with the chaff improves the buffering of the artificial turf. The length of the waste grounds is approximately 1 to 4 mm, preferably 2 to 3 mm.

상기 보조 혼합재는, 상기 왕겨와 상기 칡 찌꺼기 분쇄물을 자체 하중으로 눌어주어, 상기 왕겨와 상기 부유 방지재의 혼합을 보조한다. 상기 보조 혼합재는 토사 10 내지 20 중량%로 이루어진다. 하지만 본 발명은 이에 한정되지 않고, 규사 10 내지 20 중량%로 이루어질 수도 있다.The auxiliary mixture presses the chaff and the ground crushed matter under their own load to assist the mixing of the chaff and the anti-floating material. The auxiliary mixture consists of 10 to 20% by weight of soil sand. However, the present invention is not limited thereto, and may be made of 10 to 20% by weight of silica sand.

이하에서는, 상기 충진재를 제조하는 방법에 대하여 설명한다.Hereinafter, a method of manufacturing the filler will be described.

먼저, 왕겨 및 토사를 준비한다. 그리고, 칡 찌꺼기를 분쇄하여, 칡 찌꺼기 분쇄물을 제조한다. 그 후, 전술한 중량 비율에 따라서, 왕겨, 칡 찌꺼기 분쇄물 및 토사를 혼합하여, 상기 충진재를 완성한다.First, prepare chaff and earth and sand. Then, the ground waste is pulverized to prepare ground waste ground products. Thereafter, in accordance with the above-described weight ratio, rice hull, ground crushed ground and earth and sand are mixed to complete the filler.

상기 충진재는 장시간 고온 다습의 환경에 노출되어 사용된다. 따라서, 상기 충진재는 배수성 및 완충성뿐만 아니라, 미생물적 안정성도 있어야 한다. 상기 미생물적 안정성은 장기간 사용 시에도 상기 충진재로부터 곰팡이가 번식하지 않아야 함을 의미한다.The filler is used for a long time exposed to high temperature and high humidity environment. Therefore, the filler must have microbial stability as well as drainage and buffering properties. The microbial stability means that mold should not propagate from the filler even after long term use.

상기 미생물적 안정성 여부를 체크하기 위하여, 본 출원인에 의하여 실험이 수행되었다. 실험은 다음과 같이 수행되었다. 먼저, 왕겨 65 중량%, 칡 찌꺼기 분쇄물 20 중량% 및 토사 15 중량%를 혼합하여 충진재를 제조한다. 그 후, 상기 충진재를 35-40℃의 온도 및 다습한 상태의 공간에 두고, 7일 동안 곰팡이의 발생 여부를 육안으로 확인하였다. In order to check the microbial stability, the experiment was carried out by the applicant. The experiment was performed as follows. First, a filler is prepared by mixing 65% by weight of chaff, 20% by weight of ground flakes, and 15% by weight of soil sand. Thereafter, the filler was placed in a space of a temperature of 35-40 ° C. and a humid state, and visually confirmed whether mold was generated for 7 days.

상기 실험 결과, 7일 동안 곰팡이가 발생되지 않았음을 확인하였다. 따라서, 상기 충진재의 미생물적 안정성이 유지될 수 있음을 확인하였다.As a result of the experiment, it was confirmed that mold did not occur for 7 days. Therefore, it was confirmed that the microbial stability of the filler can be maintained.

이하에서는, 본 발명의 다른 실시예에 따른 인조잔디용 충진재에 대하여 살펴본다. 상기 충진재는, 왕겨, 부유 방지재, 보조 혼합재 및 황토를 포함한다. 상기 왕겨는 50 내지 70 중량%로 이루어지고, 상기 부유 방지재는 칡 찌거기 분쇄물 10 내지 30 중량%로 이루어지고, 상기 보조 혼합재는 토사(또는 규사) 5 내지 15 중량%로 이루어진다. 상기 왕겨, 상기 부유 방지재 및 상기 보조 혼합재의 기능은 전술한 실시예를 참조하면 된다.Hereinafter, look at with respect to the artificial turf filler according to another embodiment of the present invention. The fillers include rice hulls, anti-floating materials, auxiliary mixtures and ocher. The chaff is made of 50 to 70% by weight, the anti-floating material is made of 10 to 30% by weight of the ground crushing powder, and the auxiliary mixture is made of 5 to 15% by weight of soil sand (or silica). The function of the rice hull, the floating prevention material and the auxiliary mixture may be referred to the above-described embodiment.

상기 황토는, 상기 보조 혼합재와 함께 상기 왕겨와 상기 부유 방지재를 자체 하중으로 눌러주어, 상기 왕겨와 상기 부유 방지재의 혼합을 보조한다. 상기 황토는 10 내지 30 중량%로 이루어진다. 상기 황토의 중량%가 지나치게 높으면 상기 충진재의 완충효과가 감소한다. 또한, 상기 황토는 분진이 미세하기 때문에 상기 황토의 중량%가 지나치게 높으면, 배수 성능이 감소한다. 따라서, 상기 황토의 중량%를 30 중량% 이하로 유지하는 것이 바람직하다.The ocher presses the rice hull and the anti-floating material together with the auxiliary mixture at its own load to assist mixing of the rice hull and the anti-floating material. The loess consists of 10 to 30% by weight. When the weight percentage of the loess is too high, the buffering effect of the filler is reduced. In addition, since the loess is fine dust, if the weight percentage of the loess is too high, drainage performance is reduced. Therefore, it is desirable to keep the weight percent of the loess at 30 weight percent or less.

상기 황토는 인체와 환경에 유익한 미생물이 다량 포함되어 있어, 곰팡이 등의 서식을 억제시켜 상기 인조잔디용 충진재에 쾌적한 상태를 제공한다. 또한, 상기 황토는 상기 인조잔디용 충진재 내에서 각종 병균의 전염을 방지하고, 40∼50℃에서는 다량의 원적외선을 방출한다. 더욱이, 상기 황토는 아토피의 발생을 방지 하기 때문에, 유아나 어린이가 상기 인조잔디에서 활동하여도 아토피의 발생 위험이 크게 경감되는 효과가 있다.The ocher contains a large amount of microorganisms beneficial to the human body and the environment, thereby providing a pleasant state to the artificial turf filler by suppressing the mold and the like. In addition, the loess prevents the transmission of various germs in the filler for artificial turf, and emits a large amount of far infrared rays at 40 ~ 50 ℃. In addition, since the ocher prevents the occurrence of atopy, there is an effect that the risk of occurrence of atopy is greatly reduced even when the infant or child is active in the artificial turf.
