It works.

이하, 본 발명에 따른 하나의 바람직한 실시예를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 숯보드의 제조방법을 나타내는 공정도이고, 도 2는 도 1에 의해 제조된 숯보드의 부분절단된 사시도이고, 도 3a와 도3b는 본 발명에 적용된 철망의 사시도이다.1 is a process chart showing a method of manufacturing a charcoal board according to the present invention, Figure 2 is a partially cut perspective view of the charcoal board manufactured by Figure 1, Figures 3a and 3b is a perspective view of a wire mesh applied to the present invention.

먼저, 본 발명에 따른 숯보드의 제조방법 및 이를 이용한 숯보드는 본 출원인에 의해서 권리화된 대한민국 특허출원번호 제2007-0003559호의 광물질과 목분을 분쇄한 후 혼합하여 성형한 다음 소성하는 것을 본 발명에 기본적으로 적용된다.First, the method of manufacturing the charcoal board according to the present invention and the charcoal board using the same, and then pulverized and mixed and then pulverized the mineral material and wood flour of the Republic of Korea Patent Application No. 2007-0003559, which is right by the applicant in the present invention It is applied by default.

본 발명에 적용되는 점토는 토양이나 풍화작용을 받은 암석에서 산출되는 것으로 운모와 같은 층 구조로써 카올리류 같이 2층구조로 된 것이 있고, 몬모릴로나이트, 일라이트 등과 같이 3층 구조로 된 것도 있으며, 모래나 실트에 비해서 단위 무게당 표면적이 훨씬 넓어 수분의 보유력이 강하다.The clay applied to the present invention is produced from soil or weathered rock, and has a mica-like layer structure, which has a two-layer structure such as kaoli, and a three-layer structure such as montmorillonite, illite, etc. Compared to sand or silt, the surface area per unit weight is much wider, so the moisture retention is strong.

본 발명에 적용되는 고령토는 카올린, 백도토라고도 하는데, 바위 속에 있는 장석, 정장석, 소다 장석, 회장성 같은 장석류가 탄산 또는 물에 의해 화학적으로 분해되는 풍화에 의해 생성되는 것으로, 그 주성분은 카올리나이트(Al2O32SiO22H2O) 와 할로이사이트(Al2O3SiO24H2O) 이다.Kaolin applied to the present invention is also referred to as kaolin, white clay, feldspar, such as feldspar, feldspar, soda feldspar, ileal in the rock is produced by weathering that is chemically decomposed by carbonic acid or water, the main component is kaolinite ( Al 2 O 3 2SiO 2 2H 2 O) and halosites (Al 2 O 3 SiO 2 4H 2 O).

본 발명에 적용되는 황토는 육각 구조의 입자로 구성되어 있으며 탄산칼슘에 의하여 느슨하게 교결되어 있는 연황색 퇴적물로서 대개 균질하고 층리가 발달되어 있지 않으며, 공극률이 크고 퇴적층을 수직방향으로 갈라지게 하는 수직의 열극들이 발달해 있기 때문에 분해력, 자정력, 흡수력이 강하며 단열효과가 우수하다. 특히 실리카, 산화알루미늄 등을 주성분으로 하여 생물체에 필요한 산화철, 칼리, 칼슘, 망간 마그네슘 등의 미네랄이 포함되어 있으며 원적외선을 방출한다.The ocher applied to the present invention is composed of hexagonal particles and loosely intercalated by calcium carbonate, which is a light yellow sediment, which is usually homogeneous and not layered, and has a high porosity and a vertical splitting of the sediment layer in the vertical direction. Because of the development of the hot poles, the decomposition, self-cleaning and absorption are strong, and the thermal insulation effect is excellent. Particularly, silica, aluminum oxide, etc. are used as main components, and minerals such as iron oxide, kali, calcium, and manganese magnesium necessary for living organisms are included, and emit far infrared rays.

상기 황토, 점토, 고령토 중 선택된 어느 하나의 광물과 혼합되는 목분은 일반적인 톱밥의 형태로 되는 것으로, 하기에서 설명하는 바와 같이 소성과정을 거치면서 탄화되어 숯이 되므로 이 과정을 통해 경량화가 이루어져 보드의 중량이 감소하게 되고 숯의 효과로써 원적외선을 발생으로 혈액 순환촉진, 전자기에 의한 전자파를 산란, 음이온 발생으로 정균작용 및 탈취효과 등을 갖게 된다.The wood powder mixed with one of the minerals selected from ocher, clay, and kaolin is in the form of a general sawdust, and is carbonized during the firing process as described below. The weight is reduced and the effect of charcoal has far infrared rays, which promotes blood circulation, scatters electromagnetic waves by electromagnetic, and has bacteriostatic and deodorizing effects by generating negative ions.

이하, 본 발명에 따른 숯보드의 제조하는 방법을 각 단계별로 살펴보면 다음과 같다.Hereinafter, looking at each step of the method for producing a charcoal board according to the present invention.

1. 혼합단계1. Mixing Step

황토, 점토, 고령토 중 선택된 어느 하나의 광물질과 목분을 혼합하여 혼합분말을 수득한다.Mixed powder is obtained by mixing wood powder with any one selected from loess, clay and kaolin.

이때, 혼합분말은 상기 분쇄된 광물질 80 ~ 98중량%에 목분 2 ~ 20중량%를 혼합하여 혼합분말을 얻는다.At this time, the mixed powder is mixed with 80 to 98% by weight of the wood powder 2 to 20% by weight to obtain a mixed powder.

2. 반죽단계 2. Kneading step

혼합단계를 통해 얻은 혼합분말에 물을 투입한 후 반죽하여 반죽물을 수득한다.Water was added to the mixed powder obtained through the mixing step, followed by kneading to obtain a dough.

바람직하게 상기 반죽물은 혼합분말 60 ~ 90중량%와 물 10 ~ 40중량%를 토련기에 넣고 반죽하여 이루어진다.Preferably, the dough is made by kneading 60 to 90% by weight of the mixed powder and 10 to 40% by weight of water in a toner.

이때, 물은 상기 양보다 적게 넣게 되면 반죽이 되져 결합력이 떨어지고, 상 기 양보다 많이 널게 되면 반죽이 묽어져 건조하는 시간이 길어지게 된다.At this time, if the water is less than the amount of the dough becomes a bonding force is lowered, if more than the amount of the dough becomes thinner and the drying time becomes longer.

3. 보드성형단계3. Board Forming Step

반죽단계를 통해 얻은 반죽물을 성형틀에 투입하되, 상기 성형틀에 투입된 반죽물의 내부에 철망(30)이 위치하도록 삽입한 후 압착하여 보드로 성형한다.The dough obtained through the kneading step is put into a molding mold, and the wire mesh 30 is inserted into the dough to be placed in the mold, and then pressed into a mold.

이때, 상기 철망(30)은 도 3a 및 도 3b에 도시된 바와 같이, 통상의 와이어메쉬(32) 또는 가로방향 와이어(34a)와 세로방향 와이어(34b)가 서로 교차되는 지점에 수직방향으로 와이어(34c)가 더 형성된 와이어메쉬(34)가 적용됨이 바람직하다.At this time, the wire mesh 30 is a wire in the vertical direction at the point where the conventional wire mesh 32 or the horizontal wire 34a and the longitudinal wire 34b cross each other, as shown in Figs. 3a and 3b. It is preferable that the wire mesh 34 further formed with 34c is applied.

위와 같이 숯보드(10)의 내부에 철망(30)이 형성됨으로 인해 높은 강도를 유지하여 보다 견고한 효과가 있다.Since the wire mesh 30 is formed in the interior of the charcoal board 10 as described above, there is a more robust effect by maintaining a high strength.

4. 건조단계4. Drying Step

보드성형단계를 통해 얻은 보드성형물을 상온 또는 건조로에서 건조한다.Board molding obtained through the board forming step is dried at room temperature or drying furnace.

바람직하게 상기 보드성형물은 상온의 그늘진 곳에서 48 ~ 50시간 동안 건조하거나 50 ~ 70℃의 건조로에서 8 ~ 10시간 동안 건조시킨다.Preferably the board molding is dried for 48 to 50 hours in a shade of room temperature or for 8 to 10 hours in a drying furnace of 50 to 70 ℃.

5. 소성단계5. Firing step

건조단계를 통해 얻은 건조된 보드성형물을 소성시켜 숯보드(10)를 제조한다.By firing the dried board molding obtained through the drying step to prepare a charcoal board (10).

상기 소성은 산소가 공급되지 않는 상태의 소성로에 건조된 보드성형물을 넣고 300 ~ 500℃의 온도에서 1 ~ 4시간 동안 소성한다.The firing is put into a dried board molding in a firing furnace in the state that oxygen is not supplied and calcined for 1 to 4 hours at a temperature of 300 ~ 500 ℃.

이때, 소성과정에서 산소가 공급되지 않는 상태에서 소성가공을 하게 되면 보드성형물에 포함된 목분성분에서 탄화가 일어난다.In this case, when the plastic working is performed in a state where oxygen is not supplied in the firing process, carbonization occurs in the wood powder component included in the board molding.

소성로의 열원은 산소가 공급되는 정도에 따라서 환원염, 중성염, 산화염으로 나뉘는데, 본 발명에 적용되는 열원은 소성로 내부에 산소의 공급을 차단한 상태의 환원염에서 소성가공하는 것으로써 소성 초기에는 소성로 내의 온도가 서서히 상승함에 따라 환원염에 의하여 경화 및 탄화가 진행되는데, 이때 목분은 산화됨이 없이 분해됨으로써 축중합에 의하여 지방족 및 방향족화 되어 축합 벤젠고리를 가지고 평면상의 분자를 형성함으로써 연한 흑색의 탄화물로 된다.The heat source of the kiln is divided into reducing salts, neutral salts, and oxidizing salts according to the degree of supply of oxygen. The heat source applied to the present invention is calcined in a reducing salt in a state in which the supply of oxygen is blocked inside the kiln. As temperature rises gradually, hardening and carbonization proceed by reducing salts. In this case, wood powder is decomposed without being oxidized to be aliphatic and aromatic by condensation polymerization, forming condensed benzene rings to form flat molecules to form light black carbides. do.

이후 축합분자 상태로 되어 있는 성형물은 고열에 의하여 완전히 경화 및 탄화되면서 무정형 탄소로부터 축합분자가 수소 및 탄화수소 기체를 방출하여 육각 고리의 망평면 집합체 구조를 갖는 흑연이 되어 검은 색상을 띄게 된다.After that, the molded product is in a condensed molecule state and is completely cured and carbonized by high heat, and condensation molecules release hydrogen and hydrocarbon gas from the amorphous carbon to become graphite having a hexagonal ring network planar aggregate structure.

소성로의 온도는 300 ~ 500℃ 범위로 한정하는데, 이는 소성온도를 300℃ 미만에서 소성하게 되면 목분이 탄화되지 않으며, 500℃ 이상으로 소성하게 되면 황토성분 내에서 재결정화가 일어나 압축강도는 커지게 되나, 자연상태의 광물이 갖는 고유의 기공성이 상실되므로 황토가 갖는 장점이 없어지게 될 뿐만 아니라 에너지 낭비이다.The temperature of the kiln is limited to 300 ~ 500 ℃, which means that when the firing temperature is lower than 300 ℃, the wood powder is not carbonized. If the firing temperature is higher than 500 ℃, re-crystallization occurs in the loess component, so the compressive strength is increased. As a result, the inherent porosity of natural minerals is lost, and not only the advantages of loess are lost, but also energy waste.
