Description
본 발명은 지붕, 벽체, 방음벽 등에 사용되는 패널에 관한 것으로 보다 상세하게는 단열성능이 우수한 패널에 관한 것이다.The present invention relates to a panel used for a roof, a wall, a soundproof wall, and the like, and more particularly, to a panel having excellent heat insulating performance.
일반적으로 패널이라 함은 패널이라 함은 성형 가공된 강판에 단열재를 부착시킨 판으로 일정한 단열성능, 내화성능 및 차음성능이 유지되어야 한다.In general, a panel is a panel in which a heat insulating material is attached to a molded steel sheet, and a constant heat insulation performance, fire resistance performance, and sound insulation performance must be maintained.
그런데, 종래의 단열재의 경우 이러한 성능을 만족시키기 위하여 두꺼운 단열재를 사용하였으나, 이러한 단열재를 사용하는 경우 시공이 곤란하고, 시공 후 단열재의 두께로 인하여 내부의 공간이 축소되는 문제가 있었다. By the way, in the case of the conventional heat insulating material, a thick heat insulating material was used to satisfy this performance, but when such heat insulating material is used, the construction is difficult, and there is a problem that the internal space is reduced due to the thickness of the heat insulating material after construction.
이와 같은 문제를 해결하기 위해서 종래의 단열재 대신 글라스울, 폴리스틸렌 및 우레탄 등이 주로 사용되었다. In order to solve this problem, glass wool, polystyrene, and urethane were mainly used instead of the conventional heat insulating material.
글라스울의 경우 단열성, 차음성 및 내화성능이 우수하다는 장점이 있으나, 수분의 흡수로 인한 내구성이 저하되는 문제가 있으며, 폴리스틸렌의 경우 가연성 성분으로 내화성능을 열악한 단점이 있었다. Glass wool has an advantage of excellent heat insulation, sound insulation and fire resistance, but has a problem of deterioration in durability due to absorption of moisture, and in the case of polystyrene, there is a disadvantage of poor fire resistance as a combustible component.
또한, 우레탄의 경우도 가연성 성분으로 내화성능이 떨어지며, 화재시 유독 가스를 발생시키는 문제가 있었다.In addition, in the case of urethane, there is a problem in that the fire resistance is reduced as a combustible component, and generates toxic gas in case of fire.
본 발명은 이러한 문제점을 해결하기 위한 것으로 단열성 및 차음성이 우수하고, 내구성 및 난연성이 우수한 중간 단열재가 사용된 패널을 제공하는 데 있다. The present invention has been made to solve the above problems, and to provide a panel using an excellent intermediate heat insulating material excellent in heat insulation and sound insulation, durability and flame retardancy.
상기한 발명의 목적은 에어로젤로 이루어지는 열의 이동이 차단되는 단열재와, 상기 단열재의 양면에 형성되어 상기 단열재를 지지하는 금속 또는 비철금속 재질의 판재를 포함하여 이루어지는 패널을 제공함에 의해 달성된다.The object of the present invention is achieved by providing a panel comprising a heat insulating material which blocks the movement of heat made of airgel, and a plate made of metal or non-ferrous metal formed on both sides of the heat insulating material to support the heat insulating material.
본 발명의 바람직한 특징에 따르면, 상기 판재는 철 또는 알루미늄 합금 재질로 이루어질 수 있다. According to a preferred feature of the invention, the plate may be made of iron or aluminum alloy material.
본 발명의 바람직한 특징에 따르면, 상기 판재의 적어도 어느 한 면에는 아연 또는 갈바륨 도금층이 형성될 수 있다. According to a preferred feature of the invention, zinc or galvalume plating layer may be formed on at least one side of the plate.
본 발명의 바람직한 특징에 따르면, 상기 판재의 표면에는 폴리에스테르, 불소 또는 우레탄 중 어느 한 가지를 사용하여 코팅층이 형성될 수 있다. According to a preferred feature of the invention, the surface of the plate may be formed of a coating layer using any one of polyester, fluorine or urethane.
본 발명의 일실시예에 따른 패널은 다음과 같은 효과가 있다. Panel according to an embodiment of the present invention has the following effects.
첫째, 열전도가 잘 되지 않는 에어로젤을 사용함으로써 단열성이 뛰어난 패널을 제공할 수 있다. First, it is possible to provide a panel with excellent thermal insulation by using an airgel that is not good thermal conductivity.
둘째, 밀도가 낮은 에어로젤을 단열재로 사용함으로써 경량화된 패널을 제공할 수 있다.Second, it is possible to provide a lightweight panel by using a low density airgel as a heat insulating material.
셋째, 그믈망 형상의 구조를 가진 에어로젤을 단열재로 사용함으로써 강도가 개선된 패널을 제공할 수 있다. Third, it is possible to provide a panel having improved strength by using an aerogel having a net shape as a heat insulating material.
넷째, 아연, 갈바륨 도금이 된 판재를 사용함으로써 내식성과 내열성이 우수한 패널을 제공할 수 있다. Fourth, the panel excellent in corrosion resistance and heat resistance can be provided by using the plate | board material of zinc and galvalume plating.
다섯째, 폴리에스테르, 불소 또는 우레탄 코팅이 된 판재를 사용함으로써 내식성과 내구성 및 내습성이 우수한 패널을 제공할 수 있다. Fifth, it is possible to provide a panel excellent in corrosion resistance, durability and moisture resistance by using a plate material coated with polyester, fluorine or urethane.
이하에는, 본 발명의 바람직한 실시예를 첨부도면을 참조하여 상세하게 설명하되, 이는 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 발며을 용이하게 실시할 수 있을 정도로 상세하게 설명하기 위한 것이지, 이로 인해 본 발명의 기술적인 사상 및 범주가 한정되는 것을 의미하지는 않는다. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, which are intended to be described in detail so that those skilled in the art can easily carry out the present invention. This does not mean that the technical spirit and scope of the present invention is limited.
도 1은 본 발명의 바람직한 일실시예인 에어로젤 패널의 사시도이며, 도 2에는 도 1에 도시된 에어로젤 패널의 단면도가 도시된다. 1 is a perspective view of an airgel panel which is a preferred embodiment of the present invention, and FIG. 2 is a cross-sectional view of the airgel panel shown in FIG. 1.
본 발명에 따른 패널(1)은 에어로젤로 이루어지는 열의 이동이 차단되는 단열재(10)와, 단열재(10)의 양면에 형성되어 이 단열재(10)를 지지하는 금속 또는 비철금속 재질의 판재(20)를 포함하여 이루어진다.The
여기서, 에어로젤은 실리콘 산화물을 가수분해한 뒤 응축시키고, 임계건조시켜 만드는 것으로 부피의 약 90% 이상이 공기로 이루어져 밀도가 낮은 특성을 갖으며, 그믈망의 미세구조로 형성되어 강도가 우수한 특징이 있다. Here, the airgel is made by hydrolyzing and condensing silicon oxide and critically drying it, and having about 90% or more of the volume made of air, having low density, and having a fine structure of a mesh net, which has excellent strength. have.
또한, 에어로젤은 열전도성이 낮은 실리콘으로 성형되어 전도에 의한 열의 이동을 차단하며, 내부에 고정된 공기로 인하여 대류 및 소리를 차단한다. In addition, the aerogel is formed of silicon with low thermal conductivity to block the movement of heat by conduction, and to block convection and sound due to the air fixed inside.
따라서, 에어로젤은 단열성과 차음성이 우수한 특성을 갖는다. Therefore, the airgel has excellent thermal insulation and sound insulation properties.
더욱이 실리콘 산화물은 규소를 주성분으로 하는바 발화점이 높아, 실리콘 산화물로 형성된 에어로젤 단열재(10)는 내화성이 우수하다. Furthermore, since silicon oxide has silicon as its main component and has a high flash point, the aerogel
이러한 에어로젤로 이루어진 단열재(10)의 양면에는 단열재(10)의 형상을 유지시키 위하여 판재(20)가 결합된다. The
판재(20)의 재료로는 다양한 금속 또는 비철금속이 사용될 수 있으나, 판재(20)의 부식을 차단하기 위해서는 내식성이 높은 철 또는 알루미늄 합금 재질이 사용될 수 있다.As the material of the

이때 도금의 재료로는 판재(20)의 재료보다 부식성이 적은 재료가 사용될 수 있으나 내식성이 높은 아연 또는 갈바륨을 이용하여 도금을 하는 것이 바람직한다. In this case, a material having less corrosiveness than that of the
구체적으로 아연도금이 된 판재는 높은 내식성을 갖고 있으며, 장기간 사용한 경우에도 이러한 내식성이 유지되는 특징이 있으며, 갈바륨 도금이 된 판재는 아연도금과 알루미늄도금의 중간적 성질을 지니고 있어 아연도금 강판보다 우수한 내식성을 유지된다.Specifically, the galvanized plate has high corrosion resistance, and even after long-term use, the corrosion resistance is maintained, and the galvalume plated plate has an intermediate property between zinc plating and aluminum plating, which is superior to galvanized steel. Corrosion resistance is maintained.
또한, 아연 또는 갈바륨 도금이 된 판재의 표면에는 판재(20)를 보호하기 위하여 코팅층(25)이 형성될 수 있다.In addition, a
코팅층의 재료로는 폴리에스테르, 불소 또는 우레탄이 이용될 수 있으며, 폴리에스테르, 불소 또는 우레탄이 판재(20)의 표면에 코팅되는 경우 판재(20)의 부식에 영향을 주는 수분 및 기타 오염물질로부터 판재(20)가 보호되므로 내후성, 내식성, 내습성 및 내마모성이 우수하게 된다.Polyester, fluorine or urethane may be used as the material of the coating layer, and when the polyester, fluorine or urethane is coated on the surface of the
또 다른 바람직한 실시예인 도 3에 의하면 에어로젤 패널은 다음과 같이 실시할 수 있다. According to another preferred embodiment of FIG. 3, the airgel panel may be implemented as follows.
에어로젤의 판재(20) 중 상판에 도 3과 같이 경사턱을 연속하여 형성할 수 있으며, 사용환경에 따라 판재(20)를 엠보싱 롤로 성형할 수 있다. The inclined jaw can be continuously formed on the upper plate of the
또한, 사용환경에 따라 판재(20) 위에 다른 재료가 결합될 수 있다.In addition, other materials may be combined on the
에어로젤은 난연성, 단열성 및 차음성이 우수한 재료로 이를 단열재(10)로 사용하여 제작되는 패널(1)도 난연성, 단열성 및 차음성이 우수하다. Aerogel is a material having excellent flame retardancy, heat insulating property and sound insulation, and the
또한, 아연도금이나 갈바듈 도금이 된 판재(20)를 사용하여 패널(1)이 제작되는 경우, 내식성이 뛰어난 패널(1)을 제공할 수 있다. In addition, when the
