Description

건축물용 판넬의 제조방법{Manufacturing method of panel for building}{Manufacturing method of panel for building}

심재와, 심재 외면에 구비되는 마감시트로 이루어지는 건축물용 판넬의 제조방법에 관한 것으로, 특히 심재는 미네랄울로 된 제1난연보드와 그라스울로 된 제2난연보드를 반복적으로 다수개 구비하고, 다수개로 구비된 제1, 2난연보드 사이에 기능성바인더를 도포하여 바인더층을 형성하고, 마감시트는 금속판, 알루미늄 박판, 은박지, 시멘트보드, CRC보드, 석고보드, 목재합판 중 어느 하나로 이루어져 기존의 미네랄울 또는 그라스울 단독재질로 된 심재에 비해 습기에 강하고 높은 강도를 가질 수 있는 건축물용 판넬의 제조방법에 관한 것이다.It relates to a method of manufacturing a building panel consisting of a core material and a finishing sheet provided on the outer surface of the core material. In particular, the core material is repeatedly provided with a plurality of first flame retardant boards made of mineral wool and second flame retardant boards made of glass wool. A binder layer is formed by applying a functional binder between the first and second flame retardant boards, and the finishing sheet is made of any one of metal plate, aluminum sheet, silver foil, cement board, CRC board, gypsum board, and wood plywood, and is made of existing mineral It relates to a method of manufacturing building panels that are resistant to moisture and have high strength compared to core materials made of wool or glass wool alone.

건축물의 외벽을 담당하는 판넬은 심재와 심재를 감싸는 마감시트로 이루어진다. 판넬의 심재로 발포폴리스티로폼, 폴리우레탄이 주로 사용되며, 발포폴리스티로폼은 폴리스티렌 수지에 발포제를 넣은 다공질의 기포플라스틱으로서, 스티로폼이라고도 한다.The panel that covers the exterior wall of a building is made up of core material and a finishing sheet that surrounds the core material. Expanded polystyrofoam and polyurethane are mainly used as the core material of panels. Expanded polystyrofoam is a porous foam plastic made by adding a foaming agent to polystyrene resin, and is also called styrofoam.

이러한 발포폴리스티로폼을 심재로 사용한 발포폴리스티로폼(EPS) 판넬은 상기 발포폴리스티로폼이 전기 절연성, 특히 고주파에 대한 절연성이 우수하고 다른 단열재에 비해 단열효과가 비교적 크고 흡수율 및 비중이 작을 뿐 아니라 시공성 및 내부식성이 우수하기 때문에 건축물 판넬 시장에서, 발포폴리스티로폼을 심재로 사용한 발포폴리스티로폼(EPS) 판넬이 80% 이상을 차지하고 있다.The expanded polystyrofoam (EPS) panel using expanded polystyrofoam as the core material has excellent electrical insulation, especially high-frequency insulation, has a relatively large thermal insulation effect compared to other insulation materials, and has low water absorption and specific gravity, as well as constructability and Because of its excellent corrosion resistance, expanded polystyrofoam (EPS) panels using expanded polystyrofoam as the core material account for more than 80% of the building panel market.

그러나, 발포폴리스티로폼을 심재로 사용한 발포폴리스티로폼(EPS) 판넬은 가볍고 저렴하며 전국어디서나 생산공장이 있으므로 공급이 원활한 반면, 화재가 발생하는 경우 철판사이에서 불이 확산되기 때문에, 옆 건물의 화재 확대를 방지하기 위한 조치만 가능할 뿐, 건물이 전소될 때까지 대책이 없을 정도로 열에 취약한 단점이 있다.However, expanded polystyrofoam (EPS) panels, which use expanded polystyrofoam as the core material, are light and inexpensive and have production plants located anywhere in the country, so supply is smooth. However, if a fire breaks out, the fire spreads between steel plates, causing the fire to spread to the building next door. It has the disadvantage of being so vulnerable to heat that only measures can be taken to prevent it, and no measures can be taken until the building is completely burned down.

한편, 광석을 고온으로 용융시켜 광물질 섬유로 만드는 미네랄울과 유리 원료를 고온에서 용융한 후 고속 회전력을 이용해 섬유화해서 일정 형태로 만든 무기질의 인조 광물질 섬유로 만드는 그라스울은 건축물의 단열은 물론 내화, 흡음, 보온기능을 구비하여 판넬의 심재로 사용이 급증하고 있다.On the other hand, mineral wool, which is made of mineral fiber by melting ore at high temperature, and glass wool, which is made of inorganic artificial mineral fiber that is made by melting glass raw materials at high temperature and then fibrinizing it into a certain shape using high-speed rotation, not only insulates buildings, but also fireproofs and absorbs sound. , its use as a core material for panels is rapidly increasing due to its thermal insulation function.

하지만 미네랄울과 그라스울은 습기를 조절하는 기능이 부족해 시공 후 시간이 경과되면 곰팡이균의 최적화된 환경이 조성되어 냄새가 날수 있고, 특히 습기가 발생된 상태를 계속적으로 방치하게 되면 습기에 의한 단열성능의 저하가 일어나고 더 나아가서는 판넬의 처짐현상에 발생되는 단점이 있어왔다. However, mineral wool and glass wool lack the ability to control moisture, so as time passes after construction, an optimized environment for mold and mildew is created, which can cause odors. In particular, if moisture is continuously left unattended, the insulation performance due to moisture is reduced. There has been a disadvantage in that it causes deterioration and furthermore causes sagging of the panel.

이러한 단점을 보완하고자 미네랄울 또는 그라스울을 판넬 심재로 사용할 경우 방습포일을 같이 시공하거나 별도의 폴리우레탄이나 발포폴리스티로폼을 같이 심재로 사용하여 왔다.To compensate for these shortcomings, when using mineral wool or glass wool as a panel core material, a moisture-proof foil has been installed together, or a separate polyurethane or expanded polystyrofoam has been used as a core material.

하지만 이는 판넬 생산공정이 늘어남에 따라 판넬의 생산단가가 현저하게 높아져 가격경쟁력이 저하되고, 그 효과 또한 늘어난 생산공정에 비해 미미하여 미네랄울과 그라스울을 판넬 심재로 사용하기 위한 제조기술이 요구되고 있는 실정이다.However, as the panel production process increases, the production cost of the panel increases significantly, reducing price competitiveness, and the effect is also minimal compared to the increased production process, so manufacturing technology to use mineral wool and glass wool as panel core materials is required. am.

As shown in Figures 1 and 2, the present invention is a building panel serving as the outer wall of a building. It relates to a manufacturing method, and more specifically, to a manufacturing method of a building panel consisting of a core material and a finishing sheet (1) provided on the outer surface of the core material.

여기서, 심재는 두께 1 ~ 60㎝인 미네랄울로 된 제1난연보드(10)와 두께 1 ~ 60㎝인 그라스울로 된 제2난연보드(20)가 반복적으로 다수개 구비되고, 다수개로 구비된 제1, 2난연보드(10, 20) 사이에 기능성바인더를 도포하여 바인더층(30)을 형성한다.Here, the core material is repeatedly provided with a first flame retardant board 10 made of mineral wool with a thickness of 1 to 60 cm and a second flame retardant board 20 made with glass wool with a thickness of 1 to 60 cm. A binder layer 30 is formed by applying a functional binder between the first and second flame retardant boards 10 and 20.

제1난연보드(10)로 사용되는 미네랄울은 광석을 고온으로 용융시켜 광물질 섬유로 만드는 것이고, 제2난연보드(20)로 사용되는 그라스울은 유리 원료를 고온에서 용융한 후 고속 회전력을 이용해 섬유화해서 일정 형태로 만든 무기질의 인조 광물질 섬유로 만드는 것으로, 미네랄울과 그라스울은 건축물의 단열은 물론 내화, 흡음, 보온기능이 구비된다.The mineral wool used as the first flame retardant board (10) is made into mineral fiber by melting ore at high temperature, and the glass wool used as the second flame retardant board (20) is made by melting glass raw materials at high temperature and then converting them into fiber using high-speed rotational force. Mineral wool and glass wool are made of inorganic artificial mineral fibers made in a certain shape, and have fire resistance, sound absorption, and heat retention functions as well as insulation of buildings.

이때, 상기 기능성바인더는 소듐 실리케이트(Sodium silicate) 35 ~ 50중량%, 물 35 ~ 50중량%, 산화크로뮴(chromium oxide) 1 ~ 10중량%, 티탄 1 ~ 3중량%, 붕소 1 ~ 3중량%, 과산화나트륨(sodium peroxide), 나트륨아미드(sodium amide), 사에틸납(tetraethyl lead), 부타디엔(butadiene), 이소프렌(isoprene), 메타크릴산메틸(methyl methacrylate) 중에서 선택된 어느 1종 또는 2종 이상 혼합되는 첨가제 1 ~ 2중량%로 혼합되는 바인더 100중량부를 기준으로, 팽창흑연 30 ~ 70중량부, 탈크 5 ~ 10중량부, 발수제 5 ~ 10중량부, 분산제 1 ~ 2중량부가 포함되어 이루어진다.At this time, the functional binder is 35 to 50% by weight of sodium silicate, 35 to 50% by weight of water, Chromium oxide 1 to 10% by weight, titanium 1 to 3% by weight, boron 1 to 3% by weight, sodium peroxide, sodium amide, tetraethyl lead, butadiene ( 30 to 70 parts by weight of expanded graphite based on 100 parts by weight of binder mixed with 1 to 2% by weight of any one or two or more additives selected from butadiene, isoprene, and methyl methacrylate , 5 to 10 parts by weight of talc, 5 to 10 parts by weight of water repellent, and 1 to 2 parts by weight of dispersant.

여기서 기능성바인더는 제1, 2난연보드(10, 20) 사이에 도포되어 이루어진 바인더층(30)으로 하여금 접착력을 가져 별도의 접착제없이도 제1, 2난연보드(10, 20)와 강력한 접착력을 발휘하여 제1, 2난연보드(10, 20)의 강도 및 경도를 향상시켜 미네랄울과 그라스울로 된 제1, 2난연보드(10, 20)가 포함된 심재의 견고한 지지구조를 구현하여 건축물이 습기에 의해 손상 또는 붕괴되는 현상을 방지하게 되며, 또한 팽창흑연, 탈크 및 발수제가 기능성바인더에 추가적으로 포함되어 내열성, 난연성 및 발수성능을 구비하게 한다.Here, the functional binder has adhesive strength through the binder layer 30 applied between the first and second flame retardant boards 10 and 20, thereby demonstrating strong adhesion to the first and second flame retardant boards 10 and 20 without the use of a separate adhesive. By improving the strength and hardness of the first and second flame retardant boards (10, 20), a solid support structure of the core material containing the first and second flame retardant boards (10, 20) made of mineral wool and glass wool is implemented, thereby preventing the building from moisture. It prevents damage or collapse, and expanded graphite, talc, and water repellent are additionally included in the functional binder to provide heat resistance, flame retardancy, and water repellent performance.

기능성바인더의 소듐 실리케이트(Sodium silicate)는 높은 투광성과 낮은 열전도도를 특성으로 하기 때문에 매우 효율적인 단열기능을 담당할 수 있게 되며, 물과 혼합되었을 때 실질적인 바인더의 기능을 담당하게 되며, 또한 바인더의 내화성을 개선하기 위한 방편으로 사용된다.Sodium silicate, a functional binder, is characterized by high light transmittance and low thermal conductivity, so it can perform a very efficient thermal insulation function. When mixed with water, it functions as a practical binder, and also improves the binder's fire resistance. It is used as a way to improve.

바인더의 티탄은 백색분말로 자외선, 적외선 등을 반사시켜 기능성바인더에 의한 바인더층에 온도를 높이지 않은 역할을 함으로써 제1, 2난연보드(10, 20)의 훼손 및 변형을 방지한다.The titanium binder is a white powder that reflects ultraviolet rays, infrared rays, etc., thereby preventing damage and deformation of the first and second flame retardant boards (10, 20) by preventing the temperature of the binder layer caused by the functional binder from increasing.

바인더의 붕소는 화재시 고온으로 인해 바인더층이 열분해될 때 탄소성 탄화층을 형성할 수 있어 탄화층의 생성으로 인해 연소하는 분자의 표면에 두꺼운 장벽을 만들어 열을 차단함으로써 불이 꺼지게 할 수 있다.The boron in the binder can form a carbonaceous carbonization layer when the binder layer is thermally decomposed due to high temperature during a fire. The creation of the carbonization layer creates a thick barrier on the surface of the burning molecules, blocking heat and extinguishing the fire. .

팽창흑연은 100 ~ 300 mesh, 팽창율 250 ~ 300배 범위에서 서로 다른 사이즈 및 물성을 가진 것을 사용하여야 하며, 팽창흑연은 열을 가하면 흑연 입자가 수백배 팽창함에 따라 층 분리 현상이 발생하는 구조적 특징을 가지므로, 기능성바인더에 의한 바인더층 내에 분산된 팽창흑연은 화재로 인해 팽창된 탄화층을 형성하여 차열 및 차염의 역할을 수행할 수 있어 화염이나 불꽃이 심재에 직접 접촉되는 것을 차단하여 화재가 확산되는 것을 방지한다.Expanded graphite should be used with different sizes and physical properties ranging from 100 to 300 mesh and expansion rate of 250 to 300 times. Expanded graphite has a structural feature in which layer separation occurs as graphite particles expand hundreds of times when heated. Therefore, the expanded graphite dispersed within the binder layer by the functional binder forms an expanded carbonized layer due to the fire and can play the role of heat insulator and flame insulator, preventing the flame or flame from coming into direct contact with the core material, thereby spreading the fire. prevent it from happening.

또한, 팽창흑연은 30 ~ 70중량부 범위 내에서 서로 다른 사이즈를 채택하여 화재시 팽창크기가 서로 달라져 더욱 균일하면서 고르게 기능성바인더에 의한 바인더층 내부에서 팽창되는 것이다.In addition, expanded graphite adopts different sizes within the range of 30 to 70 parts by weight, so that the expansion size varies during fire and expands more uniformly and evenly inside the binder layer by the functional binder.

탈크는 활석광석을 미분쇄 또는 초미분쇄하여 제조된 입자 형상이 판상인 분말로서, 무기 광산물 중 가장 경도가 낮고, 화학적 안정성이 우수하며, 단가가 저렴하여 가격경쟁력이 우수한 물질이다.Talc is a powder with a plate-shaped particle shape manufactured by finely or ultrafinely grinding talc ore. It has the lowest hardness among inorganic mineral products, has excellent chemical stability, and is inexpensive, making it highly competitive in price.

즉, 바인더층에 탈크가 혼합되어 바인더층의 내열성을 향상시키는 것은 물론 방열의 기능을 구비하여 팽창흑연과 함께 탄화층을 형성하여 차열 및 차염의 역할을 수행할 수 있게 된다.In other words, talc is mixed in the binder layer, which not only improves the heat resistance of the binder layer, but also has the function of heat dissipation, forming a carbonized layer with expanded graphite to play the role of heat and flame insulation.

발수제는 제1, 2난연보드(10, 20) 사이에 수분과 오염물의 침투를 지연시켜 주는 작용을 하는 것으로 장마가 있는 여름철 장마로 인해 수분을 머금고 있는 심재가 높은 온도로 가열됨에 따라 습기를 내뿜어 심재가 축축해지거나 결로현상이 발생되는 현상을 차단하도록 하는 것이다.The water repellent acts to delay the penetration of moisture and contaminants between the first and second flame retardant boards (10, 20). As the core material, which retains moisture, is heated to a high temperature due to the rainy season during the summer, moisture is lost. This is to prevent the core material from becoming moist or condensation occurring.

발수제는 내열성과 내연성이 탁월할 뿐만 아니라 강력한 발수성능을 발휘함으로써 주변 환경에 노출되어 있는 심재의 기능과 수명을 더욱 향상시키게 한다.Water repellent not only has excellent heat resistance and flame resistance, but also exhibits strong water repellent performance, further improving the function and lifespan of the core material exposed to the surrounding environment.

분산제는 팽창흑연과 탈크가 기능성바인더로 혼합될 때 원활하게 분산시켜 팽창흑연과 탈크가 고르게 분산되어 제1, 2난연보드(10, 20) 사이에 균일하게 위치되어 난연 및 준불연기능을 향상시키도록 한다.The dispersant smoothly disperses expanded graphite and talc when they are mixed with a functional binder, so that the expanded graphite and talc are evenly dispersed and are evenly positioned between the first and second flame retardant boards (10, 20) to improve flame retardant and quasi-incombustible functions. Let’s do it.

마감시트(1)는 금속판, 알루미늄 박판, 은박지, 시멘트보드, CRC보드, 석고보드, 목재합판 중 어느 하나이며, 열반사효율이 좋고 무게가 가벼우며 가공성이 좋은 알루미늄 박판 또는 은박지를 주로 사용한다. 이러한 마감시트(1)는 판넬에 내리쬐는 열을 반사하거나 외기를 차단하여 단열기능 및 물을 방수하는 기능을 담당한다.The finishing sheet (1) is one of metal plate, aluminum sheet, silver foil, cement board, CRC board, gypsum board, and wood plywood, and aluminum sheet or silver foil, which has good heat reflection efficiency, light weight, and good processability, is mainly used. This finishing sheet (1) serves the function of insulating and waterproofing water by reflecting heat falling on the panel or blocking external air.

여기서, 미네랄울로 된 제1난연보드(10)와 그라스울로 된 제2난연보드(20)는 1 : 0.5 ~ 0.8의 두께비울로 사용될 수 있으며, 이는 미네랄울은 튼튼하며 열에 강한 기능을 가지고 있는 반면 그라스울은 가벼우면서 단열 성능이 높은 기능을 가지고 있어서 이러한 두께비율로 시공되었을 때 건출물 판넬로서의 강도와 단열기능을 충족하게 되는 것이다.Here, the first flame retardant board (10) made of mineral wool and the second flame retardant board (20) made of glass wool can be used with a thickness ratio of 1:0.5 ~ 0.8, which means that mineral wool is strong and has a heat-resistant function. On the other hand, glass wool is lightweight and has high insulation performance, so when constructed with this thickness ratio, it satisfies the strength and insulation function of a building panel.

한편, 기능성바인더에 사용되는 팽창흑연은 코팅제에 의해 코팅된 후 건조한 것을 사용하며, 이때 코팅제는 50 ~ 70℃ 온도의 물 88 ~ 90중량%, 알긴산소다 8 ~ 10중량%, 제올라이트분말 0.5 ~ 2중량%, 실리카겔 0.5 ~ 1중량%, 수산화알루미늄분말 0.5 ~ 1중량%를 혼합하여 이루어진 것이다.Meanwhile, the expanded graphite used in the functional binder is used after being coated with a coating agent and then dried. At this time, the coating agent is 88 to 90% by weight of water at a temperature of 50 to 70℃, 8 to 10% by weight of sodium alginate, and 0.5 to 2% of zeolite powder. It is made by mixing 0.5 to 1% by weight of silica gel and 0.5 to 1% by weight of aluminum hydroxide powder.

알긴산소다는 미역, 다시마, 감태와 같은 갈조류를 알칼리 추출한 후 산을 첨가하여 젤화한 것으로, 천연의 고분자 응집제로 불리울만큼 접착력이 뛰어나서 알긴산소다와 물이 혼합되어 제올라이트분말, 실리카겔, 수산화알루미늄분말 등이 발포를 통한 팽창과정에서 팽창흑연 표면에 이탈되지 않도록 구비되는 것이다.Sodium alginate is made by extracting brown algae such as seaweed, kelp, and Ecklonia cava with alkali and then adding acid to gel it. It has excellent adhesion so that it can be called a natural polymer coagulant. When sodium alginate and water are mixed, it is used to create zeolite powder, silica gel, aluminum hydroxide powder, etc. It is provided so that it does not escape from the surface of the expanded graphite during the expansion process through foaming.

즉, 알긴산소다와 혼합되어 접착력을 가지는 물은 50 ~ 70℃의 온도인 온수를 사용하며, 분말형태인 알긴산소다는 온수와 혼합하게 되면 면 점성이 발생됨으로 제올라이트분말, 실리카겔, 수산화알루미늄분말 등의 고착력이 극대화되어 팽창흑연 외측에 안정적으로 고정된다.In other words, water mixed with sodium alginate and having adhesive properties uses hot water with a temperature of 50 to 70℃. Sodium alginate in powder form becomes viscous when mixed with hot water, so it can be used in zeolite powder, silica gel, aluminum hydroxide powder, etc. The adhesion is maximized and is stably fixed to the outside of the expanded graphite.

제올라이트는 신생대 3기층의 화산재가 속성 작용을 받아 생성된 미세한 다공질로 물리적 흡착력과 화학적 양이온 치환작용이 뛰어나 수분 외 다른 물질, 즉 유해가스를 20배까지 흡수, 흡착하여 보관하고 있다가 서서히 배출하는 특이한 기능이 있어 건축용물 판넬의 원료로 사용될 경우 습도유지가 가능한 특수 기능성이 부과되고, 다공성에 의한 흡착제로써의 습도조절 능력 및 심재의 부패를 가속시키는 에틸렌 가스와 같은 물질의 포집, 형상선택성 촉매반응과 같은 특이한 구조에 의한 이온반응에 의한 항균작용을 발휘하게 되는 것이다.Zeolite is a finely porous substance created through the diagenesis of volcanic ash from the Tertiary Era of the Cenozoic Era. It has excellent physical adsorption and chemical cation substitution, and is a unique substance that absorbs and stores substances other than moisture, i.e. harmful gases, up to 20 times and then slowly releases them. When used as a raw material for building panels, it has a special functionality that can maintain humidity, has the ability to control humidity as an adsorbent due to porosity, captures substances such as ethylene gas that accelerates the decay of core materials, and has a shape-selective catalytic reaction. It exerts an antibacterial effect through an ionic reaction due to its unique structure.

실리카겔은 알카리염 등의 유기화합물을 흡착시켜 산화시킬 수 있는 강력한 산화 기능 효과가 있고 흡착력 및 방습력이 우수하여 수산화알루미늄과 함께 곰팡이균이 발생되는 것을 최소화하고 악취 및 향균 효과를 발휘하게 된다.Silica gel has a strong oxidizing function that can adsorb and oxidize organic compounds such as alkaline salts, and has excellent adsorption and moisture-proofing properties, which minimizes the occurrence of mold and mildew together with aluminum hydroxide and exerts an anti-odor and anti-bacterial effect.

수산화알루미늄은 음이온 화합물로서 음이온과 원적외선이 방출되는 특성을 가지고, 항균 및 항진균 효과와 탈취 효과를 나타낼 수 있다.Aluminum hydroxide is an anionic compound that has the property of emitting negative ions and far-infrared rays, and can exhibit antibacterial and antifungal effects and deodorizing effects.

이러한 기능성 물질들이 코팅제의 원료가 되어 팽창흑연과 함께 기능성바인더의 구성요소가 됨으로써, 천연성분인 알긴산소다를 이용하여 제올라이트분말, 실리카겔 및 수산화알루미늄분말이 팽창흑연의 외면에 접착되어 화재시 팽창흑연의 발포과정에서도 팽창된 팽창흑연에 접착되어 그 형태를 온전히 유지시켜주면서도 팽창흑연과 함께 제1, 2난연보드(10, 20) 사이에 균일하게 분포되고, 팽창흑연을 통한 난연 및 준불연기능과 더불어 향균 및 곰팡이균의 생성 및 확산을 최소화하는 심재를 제공하게 되는 효과를 가지게 되는 것이다. These functional materials become the raw materials for the coating agent and become components of the functional binder along with expanded graphite. By using sodium alginate, a natural ingredient, zeolite powder, silica gel, and aluminum hydroxide powder are bonded to the outer surface of the expanded graphite, thereby protecting the expanded graphite in the event of a fire. Even during the foaming process, it adheres to the expanded expanded graphite and maintains its shape, and is evenly distributed between the first and second flame retardant boards (10, 20) along with the expanded graphite, and has flame retardant and quasi-non-flammable functions through the expanded graphite. This has the effect of providing heartwood that minimizes the creation and spread of antibacterial and fungal bacteria.

좀 더 상세한 팽창흑연에 코팅제가 코팅되는 형태를 살펴보면, 내부 하측에 스크류 형태의 교반기가 다수 설치되며, 상부에 다수의 투입구가 형성되는 본체에 상기 팽창흑연과 코팅제를 1 : 0.5 ~ 1.5의 중량비율로 투입하게 된다.Looking at the form in which the coating agent is coated on the expanded graphite in more detail, a number of screw-shaped stirrers are installed at the bottom of the interior, and the expanded graphite and the coating agent are applied to the main body with a number of inlets at the top at a weight ratio of 1:0.5 to 1.5. It is invested as.

상기 본체에 투입된 팽창흑연과 코팅제는 스크류 형태인 다수의 교반기의 구동으로 인해 본체 내부에서 이동되면서 팽창흑연 외면에 코팅제가 코팅되면서 교반이 이루어지게 된다.The expanded graphite and coating agent added to the main body are moved inside the main body by driving a plurality of screw-type stirrers, and the coating agent is coated on the outer surface of the expanded graphite, thereby causing stirring.

상기 코팅제가 코팅된 팽창흑연은 코팅제의 점도로 서로 달라붙은 상태로 바로 사용하지 못하기 때문에, 30 ~ 60분간 비교적 저온인 5 ~ 15℃의 온도에서 건조하는 과정을 거치게 된다.Since the expanded graphite coated with the coating agent cannot be used immediately in a state where it sticks to each other due to the viscosity of the coating agent, it undergoes a drying process at a relatively low temperature of 5 to 15°C for 30 to 60 minutes.

이때 팽창흑연은 여전히 서로 달라붙은 상태이며, 이를 분리하기 위해 100 ~ 300 mesh로 이루어지는 메쉬체에 건조된 팽창흑연을 걸러준 것을 사용하여 사용상의 편의성을 향상시켜준다.At this time, the expanded graphite is still stuck to each other, and to separate it, the dried expanded graphite is filtered through a mesh sieve of 100 to 300 mesh, which improves convenience in use.

여기서, 상기 심재와 접하는 마감시트의 일면으로 소듐 실리케이트(Sodium silicate) 50 ~ 60중량%, 물 35 ~ 45중량%, 인산에스테르계 난연제와 멜라민계 난연제가 혼합된 복합 난연제 2 ~ 3중량%, 발수제 2 ~ 3중량%가 혼합된 난연성바인더를 도포할 수 있다.Here, on one side of the finishing sheet in contact with the core material, 50 to 60% by weight of sodium silicate, 35 to 45% by weight of water, 2 to 3% by weight of a composite flame retardant mixed with a phosphoric acid ester-based flame retardant and a melamine-based flame retardant, and a water repellent. A flame retardant binder mixed at 2 to 3% by weight can be applied.

소듐 실리케이트(Sodium silicate)는 무기질 난연제로 물과 같이 혼합되었을 때 접착력을 가져 별도의 접착제없이도 심재에 마감시트를 부착할 수 있게 되며, 이때 마감시트와 심재에 견고한 접착 구조를 유도함으로써, 마감시트와 심재로 된 건축용 판넬의 강도 및 경도를 향상시킴은 물론, 내열성 및 난연성을 구비하게 한다.Sodium silicate is an inorganic flame retardant that has adhesive properties when mixed with water, allowing the finishing sheet to be attached to the core material without a separate adhesive. At this time, it induces a strong adhesive structure between the finishing sheet and the core material, thereby creating a bond between the finishing sheet and the core material. It not only improves the strength and hardness of building panels made of core material, but also provides heat resistance and flame retardancy.

또한, 소듐 실리케이트(Sodium silicate)는 높은 투광성과 낮은 열전도도를 특성으로 하기 때문에 매우 효율적인 단열기능을 담당할 수 있게 된다.In addition, sodium silicate is characterized by high light transmittance and low thermal conductivity, so it can perform a very efficient insulation function.

인산에스테르계 난연제와 멜라민계 난연제가 혼합된 복합 난연제는 마감시트에 산소의 차단과 불꽃의 확대를 저지하고, 특히 화재시 불연성 가스를 발생시켜 마감시트에 공급되는 산소를 차단하여 연소를 억제시켜 건축용 판넬의 난연 및 준불연의 기능을 향상시키면서 또한 인산에스테르계 난연제와 멜라민계 난연제는 브롬계 화합물을 사용하지 않는 비할로겐계 난연제로서 이를 사용하는 건축용 판넬에 친환경적인 이점이 가져오게 한다.Composite flame retardant, which is a mixture of phosphate ester flame retardant and melamine flame retardant, blocks oxygen in the finishing sheet and prevents the spread of flames. In particular, it generates non-flammable gas in the event of a fire, blocks oxygen supplied to the finishing sheet, and suppresses combustion, making it suitable for building use. While improving the flame retardant and quasi-incombustible functions of the panel, phosphoric acid ester-based flame retardants and melamine-based flame retardants are non-halogen-based flame retardants that do not use bromine-based compounds, bringing environmentally friendly benefits to building panels using them.

발수제는 마감시트 외면에 수분과 오염물의 침투를 지연시켜 주는 작용을 하는 것으로 장마가 있는 여름철 장마로 인해 수분을 머금고 있는 건축용 판넬이 높은 온도로 가열됨에 따라 습기를 내뿜어 건축용 판넬이 축축해지거나 결로현상이 발생되는 현상을 차단하도록 하는 것이다.Water repellent acts to delay the penetration of moisture and contaminants into the outer surface of the finishing sheet. As construction panels, which retain moisture, are heated to high temperatures due to the rainy season during the summer, moisture is released, causing the construction panels to become damp or condense. The goal is to block the phenomenon from occurring.

발수제는 내열성과 내연성이 탁월할 뿐만 아니라 강력한 발수성능을 발휘함으로써 주변 환경에 노출되어 있는 건축용 판넬의 기능과 수명을 더욱 향상시키게 한다.Water repellent not only has excellent heat resistance and flame resistance, but also exhibits strong water repellent performance, further improving the function and lifespan of architectural panels exposed to the surrounding environment.

한편, 심재의 외면으로 실리카 에어로겔 20 ~ 30중량%, 파라핀 20 ~ 30중량%, 아크릴에멀젼수지 5 ~ 10중량%, 벤토나이트용액 30 ~ 40중량%, 수산화마그네슘 5 ~ 8중량%, 안티몬 2 ~ 5중량%, 백탄분말 1 ~ 3중량%로 이루어지는 코팅액과, 상기 코팅액 100중량부를 기준으로 탄산칼슘 2 ~ 5중량부, 제올라이트분말 1 ~ 2중량부, 실리카겔 1 ~ 2중량부, 수산화알루미늄분말 1 ~ 2중량부, 은행나무껍질분말 1 ~ 3중량부, 편백나무분말 1 ~ 3중량부, 벤조페논 1 ~ 3중량부가 혼합된 기능성코팅액이 코팅되어, 기능성코팅액을 통해 심재가 습기에 의해 강도가 약해지거나 곰팡이균이 발생되는 것을 방지하게 된다.Meanwhile, the outer surface of the core material contains 20 to 30% by weight of silica airgel, 20 to 30% by weight of paraffin, 5 to 10% by weight of acrylic emulsion resin, 30 to 40% by weight of bentonite solution, 5 to 8% by weight of magnesium hydroxide, and 2 to 5% of antimony. % by weight, a coating solution consisting of 1 to 3% by weight of white charcoal powder, 2 to 5 parts by weight of calcium carbonate, 1 to 2 parts by weight of zeolite powder, 1 to 2 parts by weight of silica gel, and 1 to 1 part of aluminum hydroxide powder, based on 100 parts by weight of the coating solution. A functional coating solution containing 2 parts by weight, 1 to 3 parts by weight of ginkgo bark powder, 1 to 3 parts by weight of cypress tree powder, and 1 to 3 parts by weight of benzophenone is coated, and the strength of the heartwood is weakened by moisture through the functional coating solution. This prevents mold or mildew from forming.

실리카 에어로겔은 지름이 2 ~ 10nm의 나노실리카 입자 및 지름이 1 ~ 100nm의 분산 나노가공으로 구성된 다공성 재료로서, 높은 기공률로 인해 높은 방음력, 충격흡수, 단열 등의 장점이 있으며, 특히 높은 투과성에 비해 열전도도가 매우 낮아 건축물 판넬로서의 가치가 아주 높은 것으로 평가받고 있다.Silica airgel is a porous material composed of nano-silica particles with a diameter of 2 to 10 nm and dispersed nano-processing with a diameter of 1 to 100 nm. Due to its high porosity, it has advantages such as high sound insulation, shock absorption and heat insulation, and especially high permeability. Compared to other materials, its thermal conductivity is very low, so it is evaluated as having a very high value as a building panel.

파라핀은 무색으로 휘발성이 적고, 거의 냄새가 없어 건축물 내외장재로도 많이 사용되며, 파라핀이 가지는 특유의 방습성에 의해 미네랄울과 그라스울로 된 심재에 습기가 생성되는 것을 차단하며, 해충을 방제할 수 있는 기능을 지니는 것은 물론 인체에 무해하며 친환경적이다.Paraffin is colorless, has little volatility, and has almost no odor, so it is widely used as interior and exterior materials for buildings. Paraffin's unique moisture-proof properties block moisture from forming in core materials made of mineral wool and glass wool, and can control pests.
