Description

고강도 불연 내장황토패널 제조방법{A manufacturing method for an incombustible loess panel}A manufacturing method for an incombustible loess panel

본 발명은 고강도 불연내장황토패널 제조방법에 관한 것으로, 더욱 상세하게는 황토에 미세한 닥나무 추출 섬유질(이하 '닥섬유'라 한다)을 혼합하여 친환경적이면서도 고강도이고 불연성을 갖는 패널을 제공하기 위한 고강도 불연내장황토패널 제조방법에 관한 것이다.The present invention relates to a high-strength non-combustible built-in ocher panel manufacturing method, more specifically, a high-strength non-combustible built-in for providing an environmentally friendly, high-strength and non-flammable panel by mixing the fine mulberry extract fibers (hereinafter referred to as 'duck fibers') in ocher It relates to a method for manufacturing ocher panel.

일반적으로 건축용 내장패널은 시멘트나 조적조의 몰탈 미장면, 콘크리트 표면 등을 가리기 위한 수단이나 단열 또는 실내 장식의 효과를 부여할 목적으로 사용하는 것으로, 대개 합성수지계, 무기질계, 목질계 등의 소재를 사용하고 있다.In general, building interior panels are used to cover the mortar surface of cement or masonry, concrete surfaces, etc., or to provide the effect of insulation or interior decoration. Generally, materials such as synthetic resin, inorganic, and wood are used. I use it.

그러나 상기와 같은 건축용 내장재의 경우 강도가 약하고, 불에 잘 타는 재질이어서 화재의 위험에 쉽게 노출되는 단점을 갖는다. 특히 종래 멜라민수지나 페놀수지 등과 같은 유기물 수지를 주된 점결제(粘結劑)로 사용한 건축용 내장재의 경우는 유기물의 특성상 내열성 및 내화성에 한계가 있고, 화재 발생시 유독가스의 발생 위험성이 있으며, 고온에서 판재의 강도를 유지하지 못해 건물이 취약해지는 것이어서, 최근에는 각종 화재시 연기나 유독가스가 발생되지 않도록 하고, 고온에서도 강도를 유지하여 인명피해와 재산손실을 줄이기 위한 불연성 내장판넬에 대한 연구가 활발하게 진행되고 있는 실정이다.However, in the case of the building interior materials as described above, the strength is weak, it is a material that burns well, there is a disadvantage that easily exposed to the risk of fire. In particular, in the case of building interior materials using organic resins such as melamine resins and phenol resins as main binders, there is a limit in heat resistance and fire resistance due to the nature of organic matters, and there is a risk of toxic gas generation in case of fire, The building is vulnerable due to the failure to maintain the strength of the plate. In recent years, research on non-combustible interior panels has been actively conducted to prevent smoke or toxic gases from occurring in various fires and to maintain strength at high temperatures to reduce human injury and property loss. It's going on.

지금까지의 불연내장패널은 내열성 및 내화성만 강조하다 보니 석고나 유리섬유, 암면 등과 같이 저렴하고 고온에 잘 견디는 소재만으로 내장재를 제조하여 사용해 왔으나, 이들 일부는 발암물질로써 인체에 치명적인 악영향을 주고, 일부는 휘발성 유기화합물이나 포름알데히드 같은 유해물질이 다량 방출되어 공기질을 악화시켜 인체에 극히 유해한 환경을 만들어 발병의 원인이 되며, 결로나 습기 등 물에 약해 세균이나 곰팡이 등이 쉽게 번식하고, 원형이 쉽게 변형되어, 재시공해야 하는 단점을 갖는 것이다.Until now, the non-combustible interior panel emphasizes only heat resistance and fire resistance, so it has been used to manufacture interior materials using only inexpensive and high temperature resistant materials such as gypsum, glass fiber, and rock wool, but some of them are carcinogens that have a fatal adverse effect on the human body. Some of them release harmful substances such as volatile organic compounds and formaldehyde, which deteriorate the air quality, making the environment extremely harmful to the human body and causing the onset.It is weak to water, such as condensation and moisture, and easily breeds bacteria and molds. It is easily deformed and has the disadvantage of having to be rebuilt.

물론 대리석이나 석판, 타일 등이 고급 내장재를 사용할 수도 있으나 이들은 가공성이나 생산성이 좋지 못하고, 고가의 구입비용 및 시공비가 소요되는 단점을 갖는다. 또한 무엇보다 상기와 같은 내장재는 상당한 무게를 갖는 것이어서 건물의 하중에 큰 부담을 주어 건축비의 상승과 화재시에는 강도가 떨어지고 변형이 쉬워 건물을 지탱하기 곤란한 단점을 갖는 것이다.Of course, marble, slabs, tiles and the like may use a high-quality interior materials, but they have a disadvantage in that workability and productivity are not good, and expensive purchase cost and construction cost are required. In addition, the above-mentioned interior materials have a significant weight, so that the load on the building is a great burden, the strength of the building cost and fire in the case of strength is low and deformation is difficult to easily support the building.

따라서 최근에는 친환경적인 삶을 원하는 추세에 부합하여 보다 저렴하고 가 벼우며 구하기 쉬운 광물인 황토를 사용하는 황토 패널들이 다양하게 개발되고 있다.Therefore, in recent years, various ocher panels using ocher, which is a cheaper, lighter and more easily available mineral, have been developed in response to the trend for eco-friendly life.

특히 특허출원 제10-2003-0041299호와 같이 천연황토를 물과 혼합하여 진동체를 통하여 소정직경 이상의 입자를 제거하여 황토액을 선별하는 과정과, 상기 선별된 황토에 점성을 높이도록 물에 투입하여 소정기간동안 숙성시키는 공정과, 상기 전단계에서 제조된 황토에 면섬유와 나일론사 및 닥섬유를 소정비율로 하여 교반/분쇄하는 공정과, 상기 면섬유와 혼합된 황토를 성형기에 투입하여 적정크기의 황토판을 제조하는 과정과, 상기 황토판을 이송시켜 갱지 등이 깔려있는 성형판에 안착시켜 자연건조시키는 과정으로 이루어지는 "인장강도가 보강된 건축용 황토판넬, 황토타일 조성물 및 그 제조방법"이 출원되어 있으나, 상기한 방법처럼 황토에 물을 투입하여 닥섬유를 교반/분쇄하는 경우는 물에 의해 닥섬유가 분해되면서 액상의 황토와 잘 섞이는 장점은 있으나 이는 황토를 금형에 넣고 고압의 프레스로 압착함으로써 제조할 수 있는 고강도 패널을 제조하기란 매우 곤란한 방법이다.In particular, natural ocher is mixed with water to remove particles of a predetermined diameter or more through a vibrating body, as in Patent Application No. 10-2003-0041299, and the ocher solution is selected, and the ocher is added to water to increase viscosity. And the step of aging for a predetermined period of time, the step of stirring / crushing the cotton fiber, nylon yarn and Doc fiber in the ocher prepared in the previous step at a predetermined ratio, and putting the ocher mixed with the cotton fiber into a molding machine in an appropriate size ocher plate. Has been applied for a process of manufacturing the ocher plate and the process of transporting the ocher plate and seating it on a molded plate on which pulp paper is laid, and then drying it naturally. In the case of stirring / crushing the mulberry fibers by adding water to the loess as described above, the mulberry fibers are decomposed by water and mixed well with the liquid ocher. Benefits, but this is the production of high-strength panel can be put into the yellow soil to the mold be prepared by compression in a high-pressure press method is very difficult.

왜냐하면 금형 안에 황토분말들이 수용할 수 있는 이상의 수분이 존재할 경우 프레스의 압력에 의해 눌려있던 수분이 프레스의 압력이 해제되는 순간 급격히 팽창하게 되기 때문이다. This is because, when there is more moisture in the mold than the ocher powder can accommodate, the moisture pressed by the pressure of the press expands rapidly when the pressure of the press is released.

따라서 액상의 황토와 젖어있는 상태의 닥섬유가 혼합되어 제조되는 종래의 황토패널은 물에 잘 녹는 닥섬유의 특성상 잘 교반되고 균일하게 혼합되긴하나 전기한 바와 같이 프레스성형은 할 수 없기 때문에 고강도를 가질 수 없으며 결국 성형판에 안착시켜 자연건조시킬 수밖에 없는 것이다.Therefore, the conventional ocher panel manufactured by mixing liquid ocher and wet mulberry fiber may have high strength because it is well stirred and uniformly mixed due to the characteristics of the mulberry fiber which is soluble in water, but cannot be pressed as described above. In the end, it is forced to dry on the molding plate.

따라서 제품화되기까지 오랜 시간이 소요되며, 수분을 많이 함유한 상태로 제조된 황토패널은 화재 발생시 고온에 의해 급속하게 건조되고 결국 급격히 수축함으로 인해 심한 균열이 발생하게 되고, 이로 인해 내장재로서의 강도가 저하되며, 불연재로서의 기능도 저하되는 단점을 갖는다.Therefore, it takes a long time to be commercialized, and the ocher panel manufactured in the state of containing a lot of moisture is rapidly dried by high temperature in case of fire, and severe cracks are generated due to rapid shrinkage, which causes the strength as interior materials to decrease. It also has the disadvantage that the function as a nonflammable material is also reduced.

본 발명은 가늘면서도 질기고, 가벼울 뿐만 아니라 결속성이 우수한 닥섬유를 황토분말과 혼합하여 패널을 제조하되, 신속한 건조가 가능하고 고강도의 황토패널을 제조하기 위해 물을 사용하지 않고 닥섬유와 황토분말을 교반될 수 있도록 함에 그 특징이 있다.The present invention is to prepare a panel by mixing a thin, tough, light as well as excellent duct fiber with ocher powder, while stirring the doc fiber and ocher powder without using water to produce a high-density ocher panel is possible to dry quickly It is a feature that makes it possible.

이처럼 본 발명은 닥섬유를 사용하는 기존의 황토패널 제조방법과는 달리 물을 사용하지 않고도 황토분말과 닥섬유를 교반할 수 있도록 하였으며, 이로 인해 프레스 성형과 빠른 건조가 가능하게 되어 고강도이면서 불연성이고, 경제적이면서 친환경적인 황토패널을 제공할 수 있는 매우 유용한 발명인 것이다.Thus, the present invention, unlike the conventional ocher panel manufacturing method using the mulberry fiber was able to stir the ocher powder and the mulberry fiber without using water, thereby enabling the press molding and quick drying, high strength, non-flammable, economic And yet it is a very useful invention that can provide an eco-friendly ocher panel.

본 발명은 고강도 불연황토내장패널의 제조를 위해서 고해과정을 거친 젖은 상태의 닥섬유를 건조하는 단계와, 상기 건조된 상태의 닥섬유를 혼타면 하는 단계 와, 상기 혼타면된 닥섬유와 5~25%의 함수율을 가지는 황토분말을 교반하여 혼합하는 단계와, 상기 닥섬유와 혼합된 황토분말을 금형에 넣고 프레스로 압축성형하여 패널로 제조하는 단계로 이루어진다. The present invention comprises the steps of drying the wet mulberry fiber undergoing a blasting process for the manufacture of high-strength non-combustible clay interior panel, and the step of blending the dried mulberry fiber, and 5-25% of the mixed mulberry fiber Stirring and mixing the ocher powder having a water content, and putting the ocher powder mixed with the mulberry fibers into a mold and pressing the press to form a panel.

이때 본 발명은 고해과정을 거친 젖은 상태의 닥섬유에서 펙틴, 리그닌 등과 같은 섬유결속물질을 제거하는 단계를 더 포함한다.In this case, the present invention further includes a step of removing the fiber binding material such as pectin, lignin, etc. from the docile fibers of the wet state after the beating process.

닥섬유 제조방법은 현재 널리 알려진 상태이며, 이를 이용한 황토패널제조방법 역시 널리 알려져 있다.Doc fiber manufacturing method is currently well known, ocher panel manufacturing method using the same is also widely known.

먼저 닥섬유를 제조하는 방법은 1차 가공 및 정련공정으로 닥나무 껍질을 가성소다와 같은 알카리로 처리하여 겉피를 제거하고 섬유질이 포함된 속피재료만을 얻는 단계와, 상기 1차 가공한 속피를 차아염소산 수용액 등과 같은 표백제에 담가 백피로 가공하는 단계와, 상기 표백처리된 백피는 3차 가공 및 고해 공정에 의하여 펄프로 제조하는 단계로 이루어진다.First, the method of manufacturing the mulberry fiber is the first step of processing and refining the treatment of the bark bark with alkali such as caustic soda to remove the outer skin and to obtain only the skin material containing fiber, and the primary processed skin is hypochlorous acid aqueous solution The bleached white skin is immersed in a bleach such as, and the bleached white skin is processed into pulp by a tertiary processing and beating process.

이때 알카리 처리방법으로는 10~15중량%의 가성소다수 용액에 침적하여 1~3 시간 정도 끓임으로써 닥껍질이 보다 유연해지고 섬유결속물질 및 비섬유질, 겉피(흑피)가 제거되어 진다. 이러한 공정을 한지업계에서는 자숙(煮熟) 또는 증자(蒸煮)라고 한다.At this time, as an alkali treatment method, by dipping in a caustic soda solution of 10 to 15% by weight and boiling for about 1 to 3 hours, the skin is more flexible, and the fiber binding material, the non-fiber, and the skin (black skin) are removed. Such a process is called self-cooking or increase in the Korean paper industry.

또한 닥나무 백피의 펄프화 공정은 방망이로 40∼50분정도 두들겨서 닥섬유를 찧는 방법으로 섬유를 풀어주어야 하는데 이 과정을 고해(叩解)라고 한다. 이렇게 직접 원료를 두들겨서 고해하는 것 외에 원료를 잘게 잘라 펄프화시키는 방법으 로 고해장치(비터)를 사용할 수도 있다. 상기 고해공정은 고해장치에 물을 채우고 백피를 적당량 넣어 통상 3∼5시간 바람직하게는 2∼3시간정도 회전시켜 준다.In addition, the pulp process of white paper mulberry should be released by tapping 40 to 50 minutes with bat to loosen the fiber. This process is called confession (叩 解). In addition to beating and beating the raw material directly, the beating device (bitter) can also be used as a method of finely pulverizing the raw material. In the beating process, the beating device is filled with water, and a suitable amount of white skin is added, and it is usually rotated for 3 to 5 hours, preferably 2 to 3 hours.

이처럼 고해된 닥섬유는 그대로 건조하게 되면 섬유와 섬유질을 결속시키는 펙틴, 리그닌 등의 물질들에 의해 섬유와 섬유가 엉킨 상태로 매우 딱딱하게 굳어지게 되어 혼타면 하기가 매우 곤란하게 된다. 따라서 상기 고해된 닥섬유는 혼타면을 보다 용이하게 하기 위하여 건조하기 전 펙틴, 리그닌 등과 같은 섬유결속물질을 제거하는 단계를 더 포함하도록 함이 바람직할 것이다.When the dried Dok fiber is dried as it is, pectin, lignin, etc., which bind the fiber and the fiber, are hardened in a tangled state, which makes the fiber and the fiber tangled very hard. Therefore, it may be desirable to further include the step of removing the fiber binding material such as pectin, lignin, etc., before drying to make the beating fiber more easily mixed.

본 발명에서는 상기 섬유결속물질을 제거하는 방법으로는 가성소다, 탄산칼륨, 탄산나트륨, 과황산칼륨과 같은 알칼리성분에 의해 화학적 방법을 제거하거나 펙티나제 등과 같은 펙틴분해효소로 처리하는 생화학적 방법 등이 있을 수 있다.In the present invention, the method of removing the fiber binding material is a chemical method by removing an alkaline method such as caustic soda, potassium carbonate, sodium carbonate, potassium persulfate or biochemical method of treating with a pectinase such as pectinase. This can be.

상기 가성소다수로 화학적 처리를 하는 방법은 닥섬유를 20배 내지 60배 바람직하게는 약 40배 물로 희석하고 가성소다를 1 내지 10g/ℓ, 바람직하게는 약 2.5g/ℓ 비율로 첨가하여 95℃에서 30분 내지 4시간 가열하고, 필요한 경우에는 금속이온봉쇄제 0.5 내지 2g/ℓ, 침투제 및/또는 정련제 0.5 내지 2g/ℓ, 과황산칼륨 1 내지 10g/ℓ를 첨가함으로써 가능하게 된다.The method of chemically treating with caustic soda water is diluted to 20 to 60 times preferably about 40 times water and add caustic soda at a rate of 1 to 10 g / l, preferably about 2.5 g / l at 95 ° C. Heating is carried out for 30 minutes to 4 hours, and if necessary, 0.5 to 2 g / l of metal ion sequestrant, 0.5 to 2 g / l of penetrant and / or refining agent, and 1 to 10 g / l of potassium persulfate can be added.

상기 생화학적으로 처리하는 방법으로는 닥섬유를 20배 내지 60배 바람직하게는 약 40배 물로 희석하고 펙틴분해효소 0.1 내지 10g/ℓ 바람직하게는 약 1g/ℓ 비율로 첨가하고 처리액의 pH를 약산성으로 조절하여 50 내지 70℃에서 1시간 내지 3 시간 처리한 후, 95℃ 이상에서 10분간 처리하여 효소의 활성을 제거한 다음, 탈수하고, 온수 및 냉수로 수차례 세척함으로써 가능하게 된다.In the biochemical treatment method, the mulberry fiber is diluted with 20 to 60 times preferably about 40 times water, and 0.1 to 10 g / L of pectinase is preferably added at a ratio of about 1 g / L and the pH of the treatment solution is slightly acidic. After adjusting for 1 hour to 3 hours at 50 to 70 ℃, and then treated for 10 minutes at 95 ℃ or more to remove the activity of the enzyme, it is possible to dehydrate, washed several times with hot and cold water.

이때 분산제 0.5 내지 2g/ℓ, 시판 전분 분해효소 5∼10g/ℓ비율로 펙틴분해효소에 첨가할 수도 있다. At this time, the dispersant may be added to the pectinase at a ratio of 0.5 to 2 g / l and a commercial starch enzyme 5 to 10 g / l.

이처럼 섬유결속물질이 제거된 닥섬유는 건조되더라도 딱딱해 지지 않게 되고, 따라서 혼타면이 용이해져 황토분말과 교반시 잘게 분산되면서 균일하게 혼합되어 진다. Like this, the duct fiber from which the fiber binding material is removed does not become hard even when it is dried, and thus the blend surface becomes easy, and it is finely mixed with the ocher powder and uniformly mixed.

상기 닥섬유와 혼합하기 위한 황토는 교반을 용이하게 하기 위하여 분말상태여야 하며, 함수율은 5~25%를 유지하여야 한다.The ocher for mixing with the mulberry fiber should be in a powder state to facilitate stirring, and the water content should be maintained at 5-25%.

상기 함수율은 닥섬유와 황토분말을 혼합한 다음 금형에 넣고 프레스로 가압하여 패널을 형성하고자 할 때 닥섬유와 황토분말, 황토분말과 황토분말의 결착(結着)을 가능하게 할 정도면 무방하다 할 것이며, 5% 이하의 함수율은 결착이 곤란하고, 25%이상의 함수율은 황토분말들이 수용할 수 있는 이상이 되어 프레스로 압력을 가할 경우 눌려있던 수분이 프레스의 압력이 해제되는 순간 급격히 팽창하면서 패널의 형태가 파손되기 때문에 가장 바람직한 함수율은 5~25%이다.When the moisture content is mixed with the mulberry fiber and the ocher powder, and put into a mold and pressurized by a press to form a panel, the moisture content may be sufficient to allow binding of the mulberry fiber and the ocher powder, the ocher powder and the ocher powder. , Moisture content below 5% is difficult to bind, and moisture content above 25% becomes more than acceptable for ocher powders, and when pressurized by press, the pressed water rapidly expands as soon as the press pressure is released. The most preferable water content is 5 to 25% because is broken.

이때 닥섬유와 황토분말의 혼합비율은 닥섬유 20~50중량%와 황토분말은 50~80중량%를 사용함이 바람직하다. 왜냐하면 닥섬유가 20중량% 이하일 경우에는 황토분말과의 결착력 약화로 인해 제품의 품질저하 우려가 높아지며, 50중량% 이상의 경우에는 너무 양이 많아져서 패널제조비용이 높아지기 때문이다.At this time, the mixing ratio of the mulberry fiber and ocher powder is preferably 20 to 50% by weight of the mulberry fiber and 50 to 80% by weight ocher powder. This is because if the fiber is less than 20% by weight, there is a concern that the quality of the product may be deteriorated due to the weakening of the cohesion with ocher powder.

상기 황토분말에는 제품의 특성에 다양성을 부가하기 위하여 용암성분(송이석), 운모석, 규조토 등을 첨가할 수도 있는데, 이때 첨가물의 첨가량은 용암성분(송이석), 운모석, 규조토 각각, 또는 혼합된 상태로 황토의 전체중량비 중 5~10중 량%를 차지하도록 함이 바람직하다. 이때 5중량%이하는 첨가물로 인한 제품의 특성 변화를 기대하기 곤란하며, 10중량%이상은 황토 첨가량의 감소로 인해 황토의 기능적 효과가 감소하기 때문이다. The ocher powder may be added with lava component (songstone), mica stone, diatomaceous earth, etc. in order to add variety to the characteristics of the product, wherein the addition amount of the lava component (songstone), mica stone, diatomaceous earth, or It is preferable to occupy 5 to 10% by weight of the total weight ratio of ocher in a mixed state. At this time, less than 5% by weight is difficult to expect a change in the characteristics of the product due to the additive, because more than 10% by weight of the ocher reduced the functional effect of the ocher due to the reduction of the amount of ocher.

상기 용암석분은 지하의 용암(溶岩)이 화산폭발에 의해 지표로 분출되면서 생성된 것으로, 1600℃이상의 마그마에서 산출된 자연성분이며 규사(SiO2)와 알루미나(Al2O3) 성분이 풍부하고, Ti, Ce 같은 희토류 원소들도 다량 함유하고 있어 이를 미분화(微粉化)하면 시멘트 이상의 강도(단기강도, 장기강도)를 발현할 수 있고, 다량의 결정질 화합물이 존재하므로 수화하여 경화될 때는 상당한 결합력을 가지게 되며, 미세한 기공(氣孔)이 많아 흡음효과와 악취 및 세균의 포집이 양호하고 원적외선 방출 곡선이 생체에 유익한 파장대역인 8~14 μm에서 가장 좋은 원적외선 방사율을 갖는 등 이상적인 원적외선 곡선에 가까워 인체에 유익하고 건강을 증진시킬 수 있는 건축구조물 성형에 매우 유용한 재료인 것이다. The lava stone powder is generated as the lava (지하) of the underground is ejected to the surface by the volcanic eruption, natural components calculated from magma of 1600 ℃ or more and rich in silica (SiO 2 ) and alumina (Al 2 O 3 ) components It contains a large amount of rare earth elements such as Ti, Ce, and micronized to express the strength (short-term strength, long-term strength) of cement or higher, and because a large amount of crystalline compounds exist, it has considerable bonding strength when hydrated and hardened. It has a lot of fine pores and good sound absorption effect, bad smell and bacteria collection, and the far infrared emission curve has the best far-infrared emissivity at 8 ~ 14 μm, which is beneficial to the living body. It is a very useful material for the construction of building structures that can be beneficial and promote health.

운모는 조암광물(造岩鑛物)의 하나로, 이 역시 인체에 유익한 원적외선 방사율이 좋은 재질이어서 건축내장재의 재료로 매우 유용하다.Mica is one of the bitumen minerals, and it is also very useful as a material for building interior materials because it has good far-infrared emissivity.

규조토[硅藻土, diatomaceous earth]는 평균 크기 50 내지 100 마이크로미터 크기의 규조류(diatome)라고 불리는 부유성 조류(藻類; algae) 껍데기로 이루어진 퇴적물의 집합체로써, 규조 자체의 복잡한 구조와 그 껍데기의 일차 및 이차 공극 때문에 규조토는 매우 낮은 밀도를 갖는 것이어서 본 발명 패널에 사용할 경우 흡음 및 패널의 중량 등을 감소시킬 수 있는 것이다. Diatomaceous earth is a collection of sediments composed of floating algae shells called diatome with an average size of 50 to 100 micrometers. Because of the primary and secondary pores, diatomaceous earth has a very low density, which can reduce the sound absorption and the weight of the panel when used in the panel of the present invention.
