Abstract

The present invention relates to a method for manufacturing a panel for a building in charge of an exterior wall of the building, and more specially, to a method for manufacturing a panel for a building composed of a core material and a finishing sheet provided on the outer surface of the core material. Since a flame retardant board composed of mineral wool or grass wool, and a reinforcing board consisting of one of a cement board, a gypsum board, an EPS board, a phenol board, a stone board, a honeycomb board, a wood board, a corrugated board, and an urethane board are alternately arranged, the method for manufacturing a panel for a building includes a core material having stronger strength than the conventional core material composed of the mineral wool or the grass wool alone.

Description

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

본 발명은 건축물의 외벽을 담당하는 건축물용 판넬의 제조방법에 관한 것으로, 더욱 상세히는 심재와, 심재 외면에 구비되는 마감시트로 이루어지는 건축물용 판넬의 제조방법에 관한 것으로, 특히 심재를 미네랄울 또는 그라스울로 이루어지는 난연보드 및 시멘트보드, 석고보드, EPS보드, 페놀보드, 질석보드, 허니컴보드, 목재보드, 골판지보드, 우레탄보드 중 어느 하나로 이루어지는 보강보드를 교번적으로 배치하여 기존의 미네랄울 또는 그라스울 단독재질로 된 심재에 비해 강도를 가질 수 있는 건축물용 판넬의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a panel for a building in charge of the exterior wall of a building, and more particularly, to a method for manufacturing a panel for a building comprising a core material and a finishing sheet provided on the outer surface of the core material. Reinforcement boards made of any one of flame retardant boards, cement boards, gypsum boards, EPS boards, phenolic boards, vermiculite boards, honeycomb boards, wood boards, corrugated boards, and urethane boards made of glass wool are alternately arranged to create conventional mineral wool or glass wool. It relates to a method of manufacturing a panel for a building that can have strength compared to a core material made of a single material.

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 in charge of the exterior wall of the building consists of a core material and a finishing sheet surrounding the core material. Foamed polystyrofoam and polyurethane are mainly used as the core material of the panel. Expanded polystyrofoam is a porous foamed plastic in which a foaming agent is added to polystyrene resin, 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.In the expanded polystyrofoam (EPS) panel using such expanded polystyrofoam as a core material, the expanded polystyrofoam has excellent electrical insulation, especially high-frequency insulation, and has a relatively large thermal insulation effect compared to other insulation materials, and has a small water absorption and specific gravity, as well as workability and Because of its excellent corrosion resistance, in the building panel market, expanded polystyrofoam (EPS) panels using expanded polystyrofoam as a core material account for more than 80%.

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 using expanded polystyrofoam as the core material are light and inexpensive, and supply is smooth because there are production plants anywhere in the country. It is only possible to take measures to prevent it, but it has the disadvantage of being vulnerable to heat so that there is no countermeasure until the building is 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 by melting ore at a high temperature, into mineral fibers, and glass wool, which are made into fibers using high-speed rotational force after melting glass raw materials at high temperatures, to form inorganic artificial mineral fibers that not only insulate buildings but also fire-resistance and sound-absorbing , it has a warming function, so its use as a core material for panels is rapidly increasing.

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, and as time passes after construction, an optimized environment for mold bacteria can be created and odor can occur. There has been a disadvantage in that the degradation of the panel occurs and furthermore, the deflection of the panel occurs.

이러한 단점을 보완하고자 미네랄울과 그라스울을 판넬 심재로 사용할 경우 방습포일을 같이 시공하거나 별도의 폴리우레탄이나 발포폴리스티로폼을 같이 심재로 사용하여 왔다.In order to compensate for these shortcomings, when mineral wool and glass wool are used as the core material of the panel, a moisture-proof foil has been installed or a separate polyurethane or expanded polystyrene foam has been used as the 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 panel production cost is significantly increased, which lowers the price competitiveness, and the effect is also insignificant compared to the increased production process. am.

도 1은 본 발명의 바람직한 형태를 나타내는 단면도이고, 도 2는 본 발명의 심재의 바람직한 형태를 나타내는 예시도로서, 도 1, 2에 도시된 바와 같이 본 발명은 건축물의 외벽을 담당하는 건축물용 판넬의 제조방법에 관한 것으로, 더욱 상세히는 심재와, 심재 외면에 구비되는 마감시트(1)로 이루어지는 건축물용 판넬의 제조방법에 관한 것이다.Figure 1 is a cross-sectional view showing a preferred form of the present invention, Figure 2 is an exemplary view showing a preferred form of the core material of the present invention, as shown in Figs. It relates to a manufacturing method, and more particularly, to a manufacturing method of a panel for a building made of a core material and the finishing sheet (1) provided on the outer surface of the core material.

심재는 두께 50 ~ 600㎜인 미네랄울 또는 그라스울로 된 난연보드(10)를 다수개 구비하고, 다수개로 구비된 난연보드(10) 사이에 두께 2 ~ 40㎜인 보강보드(20)를 구비하여 이루어진다.The core material is provided with a plurality of flame-retardant boards 10 made of mineral wool or glass wool having a thickness of 50 to 600 mm, and a reinforcement board 20 having a thickness of 2 to 40 mm is provided between the flame-retardant boards 10 provided in plurality. is done

난연보드(10)로 사용되는 미네랄울 또는 그라스울을 판넬의 심재로 적용할 경우 건축물의 단열은 물론 내화, 흡음, 보온기능이 구비된다.When mineral wool or glass wool used as the flame-retardant board 10 is applied as the core material of the panel, it is provided with fire-resistance, sound-absorbing, and heat-retaining functions as well as insulation of the building.

또한, 보강보드(20)는 시멘트보드, 석고보드, EPS보드, 페놀보드, 질석보드, 허니컴보드, 목재보드, 골판지보드, 우레탄보드 중 어느 하나로 이루어져 두께 50 ~ 600㎜로 이루어지는 난연보드(10) 사이에 강도가 있는 보강보드(20)를 끼워줌으로써, 미네랄울 또는 그라스울로 된 난연보드(10)에 별도의 방습포일을 시공하지 않아도 습기로 인해 발생되는 곰팡이균을 차단할 수 있고, 미네랄울 또는 그라스울 단독재질로 된 심재에 비해 강도가 향상되어 건축물이 손상 또는 붕괴되는 현상을 방지하게 되는 것이다.In addition, the reinforcing board 20 is made of any one of cement board, gypsum board, EPS board, phenol board, vermiculite board, honeycomb board, wood board, corrugated board board, and urethane board, and the flame-retardant board 10 having a thickness of 50 to 600 mm. By sandwiching the reinforcing board 20 with strength between them, it is possible to block mold fungus caused by moisture without installing a separate moisture-proof foil on the flame-retardant board 10 made of mineral wool or glass wool, and mineral wool or glass wool Compared to the core material made of a single material, the strength is improved, and the phenomenon of damage or collapse of the building is prevented.

한편, 난연보드(10)의 두께는 50 ~ 600㎜로서, 미네랄울 또는 그라스울이 생산규격에 따라 적어도 하나 이상으로 구비됨이 바람직하다.On the other hand, the thickness of the flame-retardant board 10 is 50 ~ 600 mm, it is preferable that at least one mineral wool or glass wool is provided according to the production standard.

마감시트(1)는 금속판을 사용하나 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.For the finishing sheet 1, a metal plate is used, but a thin aluminum plate or silver foil paper with good heat reflection efficiency and light weight and good workability is mainly used. This finishing sheet (1) is responsible for the function of reflecting the heat applied to the panel or blocking the outside air to the insulation function and the water-proof function.

여기서, 시멘트보드는 석회분말 100중량부를 기준으로 실리카 10 ~ 15중량부, 알루미나 10 ~ 15중량부, 산화철 5 ~ 10중량부가 혼합된 주재료 40 ~ 50중량%, 석고 3 ∼ 5중량%, 카본이 코팅된 분쇄된 유리섬유 5 ~ 7중량%, 인산암모늄 1 ∼ 3중량%, 물 40 ~ 50중량%를 혼합한 후 두께 2 ~ 40㎜인 보드형태로 성형된다.Here, the cement board contains 10 to 15 parts by weight of silica, 10 to 15 parts by weight of alumina, 5 to 10 parts by weight of iron oxide based on 100 parts by weight of lime powder, 40 to 50% by weight of the main material mixed, 3 to 5% by weight of gypsum, and carbon After mixing 5 to 7% by weight of coated pulverized glass fiber, 1-3% by weight of ammonium phosphate, and 40 to 50% by weight of water, it is molded into a board having a thickness of 2 to 40mm.

보드 형태로 성형된 성형물을 열풍으로 인해 내부가 80 ~ 90℃로 유지되는 건조기에 20 ~ 24시간 건조시키며, 건조된 보드 형태의 건조물 외면에 프라이머를 도포한 후 폴리우레아 100중량부를 기준으로, 규사 20 ~ 30중량부, 파라핀 5 ~ 10중량부, 사이클로메티콘, 사이클로펜타실록세인, 사이클로헥사실록세인, 다이메티콘 중에서 선택된 어느 1종 또는 2종 이상 혼합되는 실리콘 오일 5 ~ 10중량부, 경화제 15 ~ 25중량부가 혼합된 방수제를 도포한다.The molded product in the form of a board is dried for 20 to 24 hours in a dryer where the inside is maintained at 80 ~ 90℃ due to hot air, and after applying a primer to the outside of the dried board in the form of a material, based on 100 parts by weight of polyurea, silica sand 20-30 parts by weight, paraffin 5-10 parts by weight, cyclomethicone, cyclopentasiloxane, cyclohexasiloxane, and silicone oil 5-10 parts by weight of any one or two or more selected from dimethicone, curing agent 15 to 25 parts by weight of a mixed waterproofing agent is applied.

석회분말, 실리카, 알루미나 및 산화철은 시멘트보드의 핵심적인 주재료로 30 ~ 50중량%로 조성되어 후술되는 물을 포함한 혼합재료와 혼합됨으로써, 시멘트보드로서의 기능을 발휘할 수 있게 된다.Lime powder, silica, alumina and iron oxide are the core main materials of cement board, and are composed of 30 to 50% by weight and mixed with a mixed material including water to be described later, so that it can exert its function as a cement board.

석고는 시멘트보드를 제조할 때 응결지연시켜 시멘트보드의 크랙을 감소시키기 위해 첨가되며, 물과 팽창반응을 일으킴으로써 시멘트보드의 제조후에 표면 안정화 및 내구성 강화를 유도하게 된다.Gypsum is added to reduce cracks in cement board by delaying setting when manufacturing cement board, and by causing an expansion reaction with water, it induces surface stabilization and durability enhancement after manufacture of cement board.

이때, 석고는 과다하게 투입되면 시멘트보드의 제조 후 팽창에 의한 균열이 촉진되므로, 상기의 범위 내로 제한되는 것이 바람직하다.At this time, if the gypsum is added excessively, cracking due to expansion after manufacturing the cement board is promoted, so it is preferable to limit it within the above range.

유리섬유는 시멘트보드의 크랙을 발생을 방지하면서 시멘트보드의 압축강도 및 휨강도를 향상시키는 기능을 발휘하게 되며, 이를 위해 유리섬유는 0.1 ~ 5㎜의 길이를 가진 것을 사용함으로써 분산성을 좋게 하여 시멘트보드의 전체면에 분포된 상태를 유지하게 된다.Glass fiber prevents cracks in cement board and improves the compressive and flexural strength of cement board. It maintains the state distributed over the entire surface of the board.

이러한 유리섬유에 불연재질이면서 내열성과 내열수축성이 좋은 카본을 코팅시켜 화재시 유리섬유의 연소를 방지하여 화재의 확산을 차단하게 되며, 카본이 코팅된 유리섬유가 시멘트보드에 혼입되어 건축물 내부에서 발생하는 정전기를 효율적으로 차단할 수 있도록 한다.These glass fibers are coated with carbon, which is a non-combustible material and has good heat resistance and heat shrinkage resistance, to prevent the burning of glass fibers in case of fire and block the spread of fire. to effectively block static electricity.

또한, 카본이 코팅된 유리섬유의 함량이 상기의 함량 범위 미만이면 유리섬유에 의한 시멘트보드의 물리적 특성을 향상시키기 어렵고, 상기의 함량을 초과하면 시멘트보드로서의 기능이 유지되지 않고 유리섬유의 뭉침현상이 발생되어 분산이 용이하지 않게 된다.In addition, if the content of the carbon-coated glass fiber is less than the above content range, it is difficult to improve the physical properties of the cement board by the glass fiber. As this occurs, dispersion is not easy.

인산암모늄은 상온에서 시멘트의 경화를 촉진시켜 시멘트보드의 강도를 확보하기 위해 사용되어, 미네랄울 또는 그라스울로 된 난연보드(10) 사이에서 버팀목의 기능을 발휘하도록 한다.Ammonium phosphate is used to secure the strength of the cement board by accelerating the hardening of the cement at room temperature, so as to exhibit the function of a support between the flame-retardant boards 10 made of mineral wool or glass wool.

이렇게 제조된 시멘트보드는 카본이 코팅된 유리섬유가 포함되어 기존에 사용되던 시멘트보드에 비해 강도에 대한 물리적 특성이 향상되면서 화재의 차단 및 정전기방지 등의 기능성을 가지게 되는 것이다.The cement board manufactured in this way contains carbon-coated glass fiber, which has improved physical properties for strength compared to conventional cement boards, and has functions such as fire blocking and anti-static properties.

또한, 시멘트보드는 높은 흡수성을 가져서 방수성이 없기 때문에 수분에 취약하여 표면의 변색 및 오염이 발생되고 변색이나 오염된 부위로 세균이 발생되어 크랙이 생겨 크랙부위로 수분이 고여 시멘트보드의 손상이 발생되는 단점을 보완하고자 시멘트보드 외면에 프라이머를 도포한 후 방수제를 분사하여 방수층을 형성시킨다.In addition, because cement board has high water absorption and is not waterproof, it is vulnerable to moisture, so discoloration and contamination of the surface occur, and bacteria are generated in the discolored or contaminated area, which causes cracks. To compensate for the shortcomings, a waterproof layer is formed by applying a primer on the outer surface of the cement board and then spraying a waterproofing agent.

방수제의 주재료인 폴리우레아는 아이소사이아네이트 구성요소와 합성수지 혼합 구성요소의 반응 산물로부터 유도된 탄성 중합체로서, 피도포물에 순간적으로 완전히 접착되면서 대단히 높은 강도를 지니며, 30초 이내의 빠른 경화로 공기를 단축하며, 기계적, 물리적 화학적 물성이 매우 우수하고, 특히 내마모성, 내충격성, 내구성, 내약품성이 우수하고 시공시에 층 두께를 자유롭게 조절할 수 있어 피도포물의 피착면에 우수한 접착력을 나타내고 있다.Polyurea, the main material of waterproofing agents, is an elastic polymer derived from the reaction product of an isocyanate component and a synthetic resin mixture component. It shortens the air period, and has excellent mechanical, physical and chemical properties, especially abrasion resistance, impact resistance, durability, and chemical resistance. .

규사는 폴리우레아 및 후술되는 파라핀과 결합하여 강력한 접착력을 보유하게 되며, 이에 따라 공극률이 적어지게 되므로 온도에 의한 열팽창, 수축현상이 현저히 줄어들며, 피착면과의 접촉면적 넓어져 방수제의 부착 강도를 향상시키고, 수분의 침투에 대한 저항성이 우수해 시멘트보드의 산화에 의한 크랙을 방지하여 시멘트보드의 내구성을 향상시킨다.Silica sand has strong adhesion by combining with polyurea and paraffin, which will be described later, and as a result, the porosity is reduced, so thermal expansion and contraction due to temperature are significantly reduced. It improves the durability of cement board by preventing cracks due to oxidation of cement board as it has excellent resistance to penetration of moisture.

파라핀은 석유 중에 존재하는 탄화수소의 혼합물을 지칭하는 것으로, 방수제에 의하여 시멘트보드 외면에 형성되는 방수층이 고화되는 현상을 방지하며, 해충을 방제할 수 있는 기능을 지니는 것은 물론 인체에 무해하며 친환경적이다.Paraffin refers to a mixture of hydrocarbons present in petroleum, and prevents the waterproofing layer formed on the outer surface of the cement board from solidifying by the waterproofing agent, has a function of controlling pests, and is harmless to the human body and environment-friendly.

실리콘 오일은 방수제의 계면막을 형성시켜 방수 및 발수성능을 극대화시킬 수 있다.Silicone oil can maximize waterproofing and water repellency by forming an interfacial film of a waterproofing agent.

경화제는 시멘트보드에 방수제가 스프레이방식으로 분사되어 시공될 때 적절한 흐름성을 가져 시멘트보드와 방수제 간의 완벽한 시공이 이루어져 박리현상이 최소화하도록 구성된다.The hardener has proper flowability when the waterproofing agent is sprayed onto the cement board and is constructed so that perfect construction between the cement board and the waterproofing agent is achieved to minimize the peeling phenomenon.

이러한 방수제는 도막두께 100 ~ 200㎛이고, 도포면적 10㎡/ℓ로 형성되는 것이 바람직하며, 이는 상기의 범위 미만일 때에는 방수층의 기능을 발휘하기 어렵고, 상기의 범위를 초과할 때에는 방수제의 시공비용이 과다하게 소요되기 때문이다.Such a waterproofing agent has a coating film thickness of 100 to 200 μm, and is preferably formed with an application area of 10 m 2 / ℓ. because it takes too much.

따라서, 시멘트보드의 외면으로 방수제 분사에 의한 방수층이 형성되어 시멘트보드의 방수성능을 확보하여 수분에 의한 크랙 및 손상을 최소화시킴으로써, 내구성을 향상시킬 수 있는 효과를 가지게 되는 것이다.Therefore, a waterproofing layer is formed on the outer surface of the cement board by spraying the waterproofing agent, thereby securing the waterproofing performance of the cement board and minimizing cracks and damage due to moisture, thereby having the effect of improving durability.

또한, 보강보드(20) 중 비교적 시멘트보드 보다 강도가 약한 석고보드, EPS보드, 페놀보드, 질석보드, 허니컴보드, 목재보드, 골판지보드, 우레탄보드는 외면에 기능성바인더를 도포하여 바인더층을 형성함으로써 불연 및 준불연기능 및 강도를 향상시킬 수 있도록 한다.In addition, among the reinforcement boards 20, gypsum boards, EPS boards, phenol boards, vermiculite boards, honeycomb boards, wood boards, corrugated board boards, and urethane boards, which are comparatively weaker than cement boards, form a binder layer by applying a functional binder to the outer surface. By doing so, non-combustible and semi-non-combustible functions and strength can be improved.

이를 위해 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 포함된다.For this purpose, the functional binder is sodium silicate 35-50 wt%, water 35-50 wt%, chromium oxide 1-10 wt%, titanium 1-3 wt%, boron 1-3 wt%, Any one or a mixture of two or more selected from sodium peroxide, sodium amide, tetraethyl lead, butadiene, isoprene, methyl methacrylate Based on 100 parts by weight of the binder mixed in 1 to 2% by weight of the additive, 30 to 70 parts by weight of expanded graphite, 5 to 10 parts by weight of talc, 5 to 10 parts by weight of a water repellent, and 1 to 2 parts by weight of a dispersant are included.

여기서 바인더는 보강보드(20) 중 석고보드, EPS보드, 페놀보드, 질석보드, 허니컴보드, 목재보드, 골판지보드, 우레탄보드 외면에 도포하였을 때 접착력을 가져 별도의 접착제없이도 난연보드(10)와 강력한 접착력을 발휘하여 보강보드(20)의 강도 및 경도를 향상시켜 미네랄울 또는 그라스울로 된 난연보드(10)가 포함된 심재의 견고한 지지구조를 구현하여 건축물이 손상 또는 붕괴되는 현상을 방지하게 되며, 또한 팽창흑연, 탈크 및 발수제가 기능성바인더에 추가적으로 포함되어 내열성, 난연성 및 발수성능을 구비하게 한다.Here, the binder has adhesive strength when applied to the outer surface of the gypsum board, EPS board, phenol board, vermiculite board, honeycomb board, wood board, corrugated board board, and urethane board among the reinforcement boards 20, so that the flame-retardant board 10 and By improving the strength and hardness of the reinforcing board 20 by exerting a strong adhesive force, a strong support structure of the core including the flame-retardant board 10 made of mineral wool or glass wool is implemented to prevent the building from being damaged or collapsing. , In addition, expanded graphite, talc and water repellent are additionally included in the functional binder to provide heat resistance, flame retardancy and water repellency.

바인더의 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.Since sodium silicate of the binder has high light transmittance and low thermal conductivity, it can take on a very effective insulating function. It is used as a way to improve.

바인더의 티탄은 백색분말로 자외선, 적외선 등을 반사시켜 기능성바인더에 의한 바인더층에 온도를 높이지 않은 역할을 함으로써 보강보드(20)의 훼손 및 변형을 방지한다.The titanium of the binder is a white powder that reflects ultraviolet rays, infrared rays, etc. to prevent damage and deformation of the reinforcing board 20 by not raising the temperature of the binder layer by the functional binder.

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 carbonized layer when the binder layer is thermally decomposed due to the high temperature in the case of a 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 properties in the range of 100 to 300 mesh and 250 to 300 times the expansion rate. Expanded graphite has a structural feature that the graphite particles expand hundreds of times when heat is applied, resulting in layer separation. Therefore, the expanded graphite dispersed in the binder layer by the functional binder forms an expanded carbonized layer due to fire and can play the role of heat shielding and flame shielding. prevent it from becoming

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, the expanded graphite adopts different sizes within the range of 30 to 70 parts by weight, so that the expansion size is different in case of fire, so that it 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 plate-shaped powder produced by finely pulverizing or ultra-pulverizing talc ore. It has the lowest hardness among inorganic mineral products, has excellent chemical stability, and has excellent price competitiveness because of its low unit 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.That is, talc is mixed in the binder layer to improve the heat resistance of the binder layer, as well as to have a heat dissipation function, so that a carbonized layer is formed with expanded graphite to perform the role of heat shielding and flame shielding.

발수제는 보강보드(20) 외면에 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 agent acts to delay the penetration of moisture and contaminants to the outer surface of the reinforcement board 20, and as the core material holding moisture is heated to a high temperature due to the rainy season in summer, the core material becomes moist or This is to prevent condensation from occurring.

발수제는 내열성과 내연성이 탁월할 뿐만 아니라 강력한 발수성능을 발휘함으로써 주변 환경에 노출되어 있는 심재의 기능과 수명을 더욱 향상시키게 한다.The water repellent not only has excellent heat resistance and flame resistance, but also exhibits strong water repellency to further improve 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 보강보드 외면에 균일하게 위치되어 난연 및 준불연기능을 향상시키도록 한다.The dispersant is smoothly dispersed when the expanded graphite and talc are mixed with the functional binder so that the expanded graphite and talc are evenly dispersed and uniformly positioned on the outer surface of the reinforcing board to improve flame retardancy and semi-incombustibility.

여기서, 발수제의 상세한 조성은 물 40 ~ 50중량%, 폴리디메틸실록산 20 ~ 30중량%, 사이클로메티콘, 사이클로펜타실록세인, 사이클로헥사실록세인, 다이메티콘 중에서 선택된 어느 1종 또는 2종 이상 혼합되는 실리콘 오일 10 ~ 20중량%, 3-아미노프로필트리메톡시실란으로 된 커플링제 1 ~ 10중량%, 인산에스테르계 난연제와 멜라민계 난연제가 혼합된 복합 난연제 1 ~ 8중량%, 석영분말 1 ~ 3중량%로 이루어진다.Here, the detailed composition of the water repellent is 40 to 50% by weight of water, 20 to 30% by weight of polydimethylsiloxane, any one selected from among cyclomethicone, cyclopentasiloxane, cyclohexasiloxane, and dimethicone, or a mixture of two or more 10 to 20 wt% of silicone oil used, 1 to 10 wt% of a coupling agent made of 3-aminopropyltrimethoxysilane, 1 to 8 wt% of a compound flame retardant mixed with a phosphoric acid ester flame retardant and a melamine flame retardant, 1 to 8 wt% of quartz powder 3% by weight.

폴리디메틸실록산은 발수제에 대표적으로 사용되는 것으로, 폴리디메틸실록산의 점도는 40 ~ 90cps인 것이 바람직하며, 이와 같은 점도에서 발수제의 침투성 및 발수성이 극대화되기 때문이다.Polydimethylsiloxane is typically used in water repellents, and the viscosity of polydimethylsiloxane is preferably 40 to 90 cps, because the permeability and water repellency of the water repellent are maximized at such a viscosity.

또한, 발수제에 폴리디메틸실록산 20 ~ 30중량%를 혼합함으로써, 최적의 발수도 및 침투성을 구현하고 재료의 과다한 사용을 방지할 수 있다.In addition, by mixing 20 to 30% by weight of polydimethylsiloxane in the water repellent, it is possible to realize optimal water repellency and permeability and prevent excessive use of the material.
