외면의　화염침투방지 기능이　향상된　발포우레탄폼　단열보드　및　그　제조방법 {The urethane foam insulation board and the manufacturing method thereof in which the flame penetration prevention function of exterior is improved}{The urethane foam insulation board and the manufacturing method thereof in which the flame penetration prevention function of exterior is improved}

본 발명은, 외면의　화염침투방지 기능이　향상된　발포우레탄폼　단열보드　및　그　제조방법에 관한 것으로, 더욱 상세하게는 발포우레탄폼 단열보드의 연속생산라인에서, 발포우레탄폼의 상,하,좌우측면부에 팽창흑연난연시트를 일체로써 감싸도록 형성하여, 가볍고 단열성이 좋으면서도 화재발생시 발화시간을 지연시킴으로써 사람들로 하여금 화재현장으로부터 초기대피시간을 확보하여 신속하고 안전하게 대피할 수 있는 외면의 화염침투방지 기능이 향상된 발포우레탄폼　단열보드　및　그　제조방법에 관한 것이다.The present invention relates to a method for manufacturing a foamed urethane foam insulation board and an insulation board with improved flame penetration prevention function of the outer surface, and more particularly, in a continuous production line of foam urethane foam insulation board, the upper, lower, left and right side parts of the polyurethane foam By forming the expanded graphite flame-retardant sheet in a single body, it is lightweight and has good thermal insulation properties and delays the ignition time in case of a fire. This improved polyurethane foam 　 insulation board 　 and 　 it relates to a manufacturing method.

건축물은 전도, 대류, 복사에 의한 열손실이 일어나고 있으며 그 대부분의 열손실은 건축물의 벽체를 넘나드는 열의 이동에 의해 일어나는 열손실이 대부분을 차지하고 있다Heat loss by conduction, convection, and radiation occurs in buildings, and most of the heat loss is caused by the movement of heat across the walls of the building.

따라서 사람들은 과거로부터 건축물의 열손실을 최소화 하기 위한 여러가지 단열 노력이 끊임없이 경주되고 있다.Therefore, from the past, various insulation efforts to minimize heat loss in buildings are constantly being raced.

즉, 건축물 안팎으로 이동하는 열의 이동을 막아 줌으로써 냉, 난방에너지를 효율적으로 관리하여 저비용으로 고도의 단열효과를 얻을 수 있는 효율적인 단열방식을 추구하고 있는 것이다.In other words, by preventing the movement of heat moving in and out of the building, it is pursuing an efficient insulation method that can efficiently manage cooling and heating energy to obtain a high insulation effect at a low cost.

종래에는 건축물의 내외벽에 시트형태로 된 발포폴리에틸렌 단열재 또는 보드형태로 된 발포폴리스틸렌 단열보드 또는 발포우레탄폼 단열보드를 부착하여 양호한 단열효과를 내고 있었다.Conventionally, a sheet-form polyethylene foam insulation material or a board-type foamed polystyrene insulation board or a foamed polyurethane foam insulation board was attached to the inner and outer walls of a building to achieve good thermal insulation effect.

특히, 상기 발포우레탄폼 단열보드는 가볍고 시공이 용이하며 단열성이 좋아 건축물의 단열보드로 각광을 받고 있다.In particular, the foam urethane foam insulation board is light, easy to construct, and has good thermal insulation properties, so it is in the spotlight as an insulation board for buildings.

그러나, 상기 발포우레탄폼 단열보드는 화재 발생시에는 화염에 매우 취약하여 발화될 경우 유독가스를 발생시키기 때문에 사람들이 질식사 하게 되는 등 인명피해를 가져오게 될 위험요인을 안고 있다. However, since the polyurethane foam insulation board is very vulnerable to flames when a fire occurs, and when ignited, it generates toxic gas, so people are suffocated, etc.

따라서, 화재발생시 발화시간을 지연시켜 줌으로써 사람들로 하여금 화재현장으로부터 초기대피시간을 확보하여 신속하고 안전하게 대피할 수 있는 외면의 화염침투방지 기능이 향상된 단열보드의 개발이 절실히 요구되고 있는 실정이다.Therefore, there is an urgent need for the development of an insulation board with improved flame penetration prevention function on the outer surface that allows people to quickly and safely evacuate by securing the initial evacuation time from the fire site by delaying the ignition time in case of a fire.

The expanded graphite flame-retardant sheet for the upper part (E1), the expanded graphite flame-retardant sheet for the bottom part (E2), the expanded graphite flame-retardant sheet for the left side part (E3), and the expanded graphite flame-retardant sheet (E4) for the right side part are formed by cutting according to the roll shape, respectively. It is a step of winding up to form a winding roll.

흑연(graphite)은 탄소의 결정형의 하나로, 평면 육각형의 탄소 원자가 결합되어 이루어진 시트형태가 겹겹이 쌓인 층상구조를 하고 있어 이러한 층간 결합은 박리 되기 쉬운 결합으로 되어 있다.Graphite is one of the crystalline forms of carbon, and the sheet shape formed by bonding planar hexagonal carbon atoms has a layered structure in which the interlayer bonding is easily peeled off.

이와 같은 흑연의 층상구조 사이 사이에 황이나 질소화합물을 주입한 흑연층간화합물에 열을 가하게 되면, 층간에 삽입된 물질이 연소되며 가스화 되는데, 그 때에 생긴 가스의 방출이 층과 층 사이를 폭발적으로 확대시키며 경우에 따라서는 수 백배 팽창하게 되는 팽창흑연(expandable graphite)을 형성하게 된다.When heat is applied to the graphite interlayer compound injected with sulfur or nitrogen compound between the layered structures of graphite, the material inserted between the layers is combusted and gasified. It expands to form expandable graphite, which in some cases expands several hundred times.
