Description
본 발명은 샌드위치 패널, 단열재, 내화패널, 건축용 내.외장재 패널 등에 부착하여 사용하는 난연성 건축용 패널 구조에 관한 것이다. The present invention relates to a flame retardant building panel structure used by attaching to a sandwich panel, a heat insulating material, a fireproof panel, a building interior/exterior panel, and the like.
일반적으로, 건축용 샌드위치 패널은 E.P.S 보드(Expanded Polystyren Board)나 유리섬유보드(Glass Wool Board), 발포 우레탄을 내부 단열보드로 사용하고, 상기 내부 단열보드의 외부면에 아연도금 강판으로 이루어지는 표면판재와 결합한 구성으로 이루어져 있으며, 특히 상기 건축용 샌드위치 패널은 내부로의 화염전파를 근본적으로 차단하여 건축용 패널의 보호는 물론, 열에 의한 건축용 패널의 탄화현상을 방지하여 연기 및 유해가스의 발생을 현저하게 감소시켜 화재로 인한 건축용 패널의 유해성을 최소화하여 인체나 환경에 피해를 주지 않도록 하는 난연성 패널을 제공하고 있다.In general, a sandwich panel for construction uses an E.P.S board (Expanded Polystyren Board), a glass fiber board (Glass Wool Board), or foamed urethane as an internal insulation board, and a surface plate made of galvanized steel sheet on the outer surface of the internal insulation board and In particular, the architectural sandwich panel fundamentally blocks flame propagation to the inside to protect the building panel, as well as prevent carbonization of the building panel due to heat, thereby significantly reducing the generation of smoke and harmful gases We are providing a flame retardant panel that minimizes the harmfulness of building panels due to fire and prevents damage to the human body or the environment.
본 발명은 난연성이 포함된 아연도금 강판을 이용하여 건축용 난연 패널의 제조원가를 줄이고, 화염으로 부터 단열보드를 보호할 수 있도록 함을 기술적 과제로 삼는다.The present invention makes it a technical problem to reduce the manufacturing cost of a flame retardant panel for construction by using a galvanized steel sheet containing flame retardancy, and to protect the insulation board from flame.
본 발명은 내부에 심재로서 단열보드를 표면판재인 아연도금 강판과 아연도금 강판 사이에 게재하고, 상기 아연도금 강판과 아연도금 강판의 양단에 형성한 결합부재에 의해 결합하여 구성하는 것에 있어서, 상기 아연도금 강판을 구성하는 내측 용융 아연도금층에 난연성 도료층이 코팅된 아연도금 강판을 사용하여 구성함을 특징으로 한다.In the present invention, in the configuration in which an insulation board as a core material is placed between a galvanized steel sheet as a surface plate material and a galvanized steel sheet, and coupled by coupling members formed at both ends of the galvanized steel sheet and the galvanized steel sheet, It is characterized in that it is constituted by using a galvanized steel sheet coated with a flame retardant paint layer on the inner hot-dip galvanized layer constituting the galvanized steel sheet.
본 발명은 이송되는 강판 내측면에 난연성 도료층을 도포한 다음 상기 난연성 도료층을 고온으로 건조시켜 난연성 아연도금 강판을 제공함으로서 연속적으로 얻어진 난연성 아연도금 강판을 이용하여 난연성 건축용 패널을 구성하므로, 별도로 단열보드에 난연성 도료를 분무하거나 도포하는 별도의 공정을 거치지 않고 난연성 패널을 제작할 수 있어 난연 패널의 제조원가를 크게 줄일 수 있는 효과와 외부의 화염에 의한 고온이 아연도금 강판 내측면에 설치된 단열보드측으로 전파되는 것을 강하게 억제시킬 수 있어 난연효과를 크게 증진시키는 효과를 가진다.The present invention forms a flame retardant building panel using a flame retardant galvanized steel sheet continuously obtained by applying a flame retardant paint layer on the inner surface of a steel sheet to be transported and then drying the flame retardant paint layer at a high temperature to provide a flame retardant galvanized steel sheet. The flame retardant panel can be manufactured without going through a separate process of spraying or applying flame retardant paint on the insulation board, which greatly reduces the manufacturing cost of the flame retardant panel, and the high temperature caused by the external flame is directed toward the insulation board installed on the inner side of the galvanized steel sheet. It can strongly suppress the propagation and has the effect of greatly enhancing the flame retardant effect.

이와 같이 이루어지는 본 발명은 연속적으로 코일형태로 권취되는 아연도금 강판(10) 내측면에 난연성 도료층(13)을 도포하여 오븐실에서 180℃ ~ 320℃ 온도로 건조시키는 1차 건조단계(S6) 및 2차 건조단계(S8)를 거쳐 코팅 처리하게 되므로 아연도금 강판(10) 제조과정에서 난연성을 부여할 수 있게되고, 이와같이하여 얻어진 아연도금 강판(10)은 난연성 건축용 패널(20)로서 제공할 경우 별도의 난연성 도료 제조공정을 거치지 않고서도 건축용 패널(20)을 제작할 수 있으므로 건축용 패널(20)의 제조원가를 대폭 절감할 수 있고, 특히 화재 발생 시 외부의 화염이 아연도금 강판(10)에 전달될 경우 높은 온도의 고온에 의해 아연도금 강판(10) 내측면에 코팅된 난연성 도료층(13)이 팽창하여 난연층을 형성하게 되므로 공기의 흐름을 차단하고, 단열보드 내측으로의 화염전파를 근원적으로 차단하게 됨으로써 건축용 패널의 보호는 물론, 열에 의한 건축용 패널의 탄화현상을 배제하여In the present invention made as described above, the first drying step (S6) of coating the flame retardant paint layer 13 on the inner surface of the galvanized steel sheet 10 continuously wound in a coil form and drying it in an oven chamber at a temperature of 180 ° C to 320 ° C and the secondary drying step (S8), so that flame retardancy can be imparted in the manufacturing process of the galvanized steel sheet 10, and the galvanized steel sheet 10 obtained in this way can be provided as a flame retardant building panel 20. In this case, since the building panel 20 can be manufactured without going through a separate flame retardant paint manufacturing process, the manufacturing cost of the building panel 20 can be significantly reduced. In this case, the flame retardant paint layer 13 coated on the inner surface of the galvanized steel sheet 10 expands to form a flame retardant layer due to the high temperature of the galvanized steel sheet 10, thereby blocking the flow of air and fundamentally preventing flame propagation into the inside of the insulation board. By blocking it, it not only protects the building panel, but also eliminates the carbonization of the building panel due to heat.
