본 발명은 외부피복의 차열성이 강화되어 화재안전성이 향상된 복합단열보드 제조방법 및 그 방법으로 제조된 외부피복의 차열성이 강화되어 화재안전성이 향상된 복합단열보드에 관한 것으로써, 더욱 상세하게는 건축물 내,외벽에 부착되는 복합단열보드에 있어서, 상기 복합단열보드의 외부피복이 건축물의 실내공간을 잠식하지 않으면서도, 화재 발생시에는 복합단열보드의 속재가 발화되는 시간을 최대한 늦춰 줌으로써 복합단열보드의 속재가 발화되어 치명적인 유독가스를 발생시키기 전에 사람들이 먼저 안전하게 대피할 수 있도록 초기대피시간을 확보하여 줄 수 있는 외부피복의 차열성이 강화되어 화재안전성이 향상된 복합단열보드 제조방법 및 그 방법으로 제조된 외부피복의 차열성이 강화되어 화재안전성이 향상된 복합단열보드에 관한 것이다.The present invention relates to a method for manufacturing a composite insulation board with improved fire safety by strengthening the heat shielding property of the outer coating, and to a composite insulation board with improved fire safety by strengthening the heat shielding property of the outer coating manufactured by the method, and more particularly, In the composite insulation board attached to the inner and outer walls of a building, the outer coating of the composite insulation board does not encroach on the interior space of the building, and in the event of a fire, the composite insulation board by delaying the ignition time as much as possible A method for manufacturing a composite insulation board with improved fire safety by strengthening the heat shielding properties of the outer coating, which can secure an initial evacuation time so that people can safely evacuate before the inner material of the product ignites and generates fatal toxic gas. It relates to a composite insulation board with improved fire safety by strengthening the heat shielding properties of the manufactured outer coating.

건축물에는 외기의 침투를 방지하고 내부의 열이 외부로 유출되는 것을 방지하기 위해 내,외벽에 단열재로 단열시공을 하고 있다.In order to prevent the infiltration of outside air and the leakage of internal heat to the outside, the building is insulated with an insulating material on the inside and outside walls.

단열재로는 단열시트 형태의 단열재와 단열보드 형태의 단열재를 사용하고 있는데, 단열성이 좋고 가벼워 작업성이 좋으며 값이 비교적 저렴한 스티로폼, 우레탄폼으로 성형된 단열보드 형태의 단열재가 많이 사용되고 있다.Insulation materials in the form of insulating sheets and insulating boards are used. Insulation boards made of Styrofoam and urethane foam, which have good thermal insulation properties, are lightweight, have good workability, and are relatively inexpensive.

그런데 위와 같은 단열보드재는 단열성과, 경제성, 작업성의 면에서는 매우 우수한 장점을 가지고 있으나, 반면에 화재가 발생했을 때에는 쉽게 발화되어 연소되며 연소시에는 다량의 유독가스를 내뿜으며 연소되므로 사람들이 대피할 틈도없이 호흡기를 통해 유독가스가 흡입되어 급기야 인명피해로 이어지고 있다. However, the above insulation board material has very good advantages in terms of insulation, economic feasibility, and workability. On the other hand, when a fire occurs, it is easily ignited and burned. Toxic gas is inhaled through the respiratory tract without a break, leading to casualties.

이에 대한 대책으로 종래에는 단열보드재의 양면에 난연재인 알루미늄필름을 융착하여 제작한 복합단열보드를 사용하여 복사열을 차단하는 효과를 노림과 동시에 화재 발생시 내부 단열보드재에 화염이 전파되어 발화되는 속도를 늦춰줌으로써 사람들이 화재로부터 대피할 수 있는 시간을 확보하려는 시도가 있어 왔다.As a countermeasure against this, conventionally, a composite insulation board made by fusing an aluminum film, a flame retardant material, on both sides of an insulation board material is used to block radiation heat, and at the same time, when a fire occurs, the flame propagates to the inner insulation board material and ignites. Attempts have been made to provide time for people to evacuate from the fire by slowing it down.

그런데 단열보드재 양면에 융착된 알루미늄필름 피복은 화염의 열기가 통과되므로 화재 발생시 단열보드에 화염의 열기가 쉽게 전달되어 단열보드재가 용융되며 발화되어 유독가스를 발생시키게 되므로, 위와 같은 시도에도 불구하고 사람들은 대피할 시간도 없이 속수무책으로 유독가스에 질식되어 목숨을 잃게 되는 상황에 직면하고 만다.However, since the heat of the flame passes through the aluminum film coating on both sides of the insulation board, in case of a fire, the heat of the flame is easily transmitted to the insulation board, causing the insulation board material to melt and ignite, generating toxic gas. People have no time to evacuate and are helplessly suffocated by the poisonous gas and face a situation where they lose their lives.

그렇다고 단열보드재의 양면에 난연피복을 지나치게 두텁게 부착하는 것은 건축물의 실내 공간이 협소해지게 되는 문제점이 있었다.However, attaching the flame-retardant coating on both sides of the insulation board material too thickly has a problem in that the indoor space of the building is narrowed.

이하 좀더 자세히 설명한다.It will be described in more detail below.

1. 단열보드재 형성단계(S1)1. Insulation board material forming step (S1)

상기 단열보드재 형성단계(S1)는, 도2의(a)(b)(c)에 나타낸 것과 같이, '보드 형태', '시트 형태' 또는 '적층시트 형태'의 어느 하나로 된 단열보드재(이하 설명의 편의상 통칭 ‘단열보드재(100)’라고 칭하기로 한다)를 형성하는 단계이다.The insulating board material forming step (S1), as shown in (a) (b) (c) of Figure 2, a 'board form', 'sheet form' or 'laminated sheet form' of any one of the insulation board material (hereinafter referred to as 'insulation board material 100' for convenience of description) is a step of forming.

먼저, 상기 단열보드재(100) 중 도2의 (a)에 나타낸 것과 같은‘보드 형태’의 단열보드재(110)는, 비드법발포폴리스틸렌보드(EPS), 압출법발포폴리스틸렌보드(XPS), 발포우레탄보드(PUR), 발포페놀폼보드(PF) 또는 발포폴리프로필렌보드(PP)와 같은 부피형단열보드재 중 선택되는 어느 하나의 '판형으로 된 단열보드(111)'일 수 있다.First, among the insulation board materials 100, the insulation board material 110 of a 'board form' as shown in FIG. 2 (a) is a bead method foamed polystyrene board (EPS), an extrusion method foamed polystyrene board (XPS). , foam urethane board (PUR), foam phenol foam board (PF) or foamed polypropylene board (PP) may be any one of 'plate-type insulation boards 111' selected from bulky insulation board materials.

상기 판형으로 된 단열보드(111)의 양면 또는 일면에 알루미늄필름(210)이 융착되어‘보드 형태’의 단열보드재(110)를 형성하게 된다.The aluminum film 210 is fused to both sides or one surface of the plate-shaped insulation board 111 to form the insulation board material 110 in the form of a 'board'.

이때, 도면에 도시하지는 않았으나, 도4로부터 유추 가능하듯이, 일면에 알루미늄필름(210)이 융착된 상기 판형으로 된 단열보드(111)의 타면에는, 소정 두께의 글라스울시트, 암면시트 또는 부직포시트와 같은 난연재시트(230)를 융착하여 ‘보드 형태’의 단열보드재(110)를 형성하는 것도 가능하다.At this time, although not shown in the drawings, as can be inferred from FIG. 4 , on the other surface of the plate-shaped insulation board 111 to which an aluminum film 210 is fused to one surface, a glass wool sheet, rock wool sheet or nonwoven fabric having a predetermined thickness It is also possible to form the insulation board material 110 of a 'board shape' by fusing the flame retardant sheet 230 such as a sheet.

다음, 상기 단열보드재(100) 중 도2의 (b)에 나타낸 것과 같은‘시트 형태’의 단열보드재(120)는, 도5에 나타낸 것과 같이, 통상 폴리에틸렌 그물망시트(PE 또는 PP, PU, PVC 중 선택되는 어느 하나로 된 그물망시트, 121)의 양면에 알루미늄필름(210)을 융착하여 양 알루미늄필름 사이에 닫힌셀(closed cell) 구조의 밀폐된 공기층을 형성한 시트형태의 단열보드재(120)를 말한다.Next, the insulation board material 120 of the 'sheet form' as shown in FIG. 2 (b) of the insulation board material 100, as shown in FIG. 5, is usually a polyethylene mesh sheet (PE or PP, PU) Insulation board material in the form of a sheet in which an aluminum film 210 is fused on both sides of a mesh sheet 121 made of any one selected from among , PVC, and an airtight layer of a closed cell structure is formed between the two aluminum films ( 120) is said.

또한, 상기 단열보드재(100) 중 도2의 (c)에 나타낸 것과 같은‘적층시트 형태’의 단열보드재(130)는, 도6에 나타낸 것과 같이, 상기의 폴리에틸렌 그물망시트(121)의 양면에 알루미늄필름(210)을 융착하여 형성된 상기 ‘시트 형태’의 단열보드재(120)를 다수개 적층 융착하여 형성한 적층시트 형태의 단열보드재(130)를 말한다.In addition, the insulation board material 130 of the 'laminated sheet form' as shown in Fig. 2 (c) of the insulation board material 100 is, as shown in Fig. 6, the polyethylene mesh sheet 121 of the It refers to the insulation board material 130 in the form of a laminated sheet formed by laminating and fusing a plurality of the 'sheet type' insulation board material 120 formed by welding the aluminum film 210 on both sides.

상기‘보드 형태’단열보드재(110)와‘시트 형태’단열보드재(120) 및‘적층시트 형태’단열보드재(130) 즉 통틀어 단열보드재(100)는, 열전도율이 매우 낮아서 건축물의 내,외벽에 부착하여 열의 이동을 차단하는 효과가 매우 크므로 건축물의 보온재로써 각광을 받고 있다.The 'board type' insulation board material 110, the 'sheet type' insulation board material 120, and the 'laminated sheet type' insulation board material 130, that is, the insulation board material 100 as a whole, has very low thermal conductivity, so the thermal conductivity of the building is very low. Since it is attached to the inner and outer walls and blocks the movement of heat, it is in the spotlight as a thermal insulation material for buildings.

그러나, 화재발생시에는 화재에 취약하여 내부의 가연성 단열보드재(100)가 발화되면서 유독가스를 발생시켜 인명피해를 초래하곤 한다.However, when a fire occurs, it is vulnerable to fire, and the internal combustible insulation board material 100 is ignited and toxic gas is generated to cause damage to human life.

2. 시트형태피복체 형성단계(S2)2. Sheet form covering body forming step (S2)

상기 시트형태피복체 형성단계(S2)는, 상기 단열보드재(100)의 양면 또는 일면을 피복하기 위한 시트형태피복체(200)를 형성하는 단계이다.The sheet-form covering body forming step (S2) is a step of forming a sheet-like covering body 200 for covering both sides or one side of the insulating board material 100 .

상기 시트형태피복체(200)는, 도7에 나타낸 것과 같이, 알루미늄필름(210)의 일면에 난연재도포액(220)인 팽창흑연도포액(221)을 도포 또는 분사한 후 거기에 다른 또 하나의 알루미늄필름(210)을 융착하여 시트형태피복체(200)를 형성하는 것도 가능하고, 도8에 나타낸 것과 같이, 상기 시트형태의 난연재시트(230) 양면에 알루미늄필름(210)을 융착하여 시트형태피복체(200)를 형성하는 것도 가능하다.As shown in FIG. 7, the sheet-type covering body 200 is coated or sprayed with the expanded graphite coating solution 221, which is the flame retardant coating solution 220, on one surface of the aluminum film 210, and then another one thereon. It is also possible to form the sheet-type covering body 200 by fusing the aluminum film 210 of It is also possible to form the shape covering body (200).

상기 알루미늄필름(210)은, 기본적으로 난연재이지만, 도3에 나타낸 것과 같이, 그 일면에는 플라스틱 코팅제(211)가 도포된다.The aluminum film 210 is basically a flame retardant, but as shown in FIG. 3 , a plastic coating agent 211 is applied on one surface thereof.

상기와 같은 알루미늄필름(210)은, 화재발생시에는 일면에 코팅된 플라스틱 코팅제(211)가 연소되며 부풀어올라, 도10에 나타낸 것과 같이, 소정폭의 공기층(212)을 형성하게 된다.The aluminum film 210 as described above, when a fire occurs, the plastic coating agent 211 coated on one surface is burned and swelled, as shown in FIG. 10 , to form an air layer 212 of a predetermined width.

상기 공기층(212)은, 화재 발생시 화염의 전파를 지연시켜 사람들이 화염과 유독가스로부터 안전하게 대피할 수 있는 초기대피시간을 확보하는데 일조하게 된다.The air layer 212 helps to secure the initial evacuation time for people to safely evacuate from the flame and toxic gas by delaying the propagation of the flame when a fire occurs.

따라서, 상기 플라스틱 코팅제(211)가 일면에 코팅된 알루미늄필름(210)은, 복수 내지 다수겹을 융착하여 사용할 때 화염 전파 억지 효과는 더욱 커지게 될 것이다.Accordingly, when the plastic coating agent 211 is coated on one surface of the aluminum film 210 and used by fusion bonding a plurality of layers, the flame propagation inhibiting effect will be further increased.

참고로, 본 발명의 설명 전체에서, 상기 알루미늄필름(210)의 두께는 0.001mm이상 0.5mm미만이면 무난하다.For reference, throughout the description of the present invention, the thickness of the aluminum film 210 may be 0.001 mm or more and less than 0.5 mm.

상기 알루미늄필름(210)의 두께가 0.001mm미만이면 차열효과가 미미하고, 0.5mm이상인 것은 경제성이 없어 바람직하지 않다.If the thickness of the aluminum film 210 is less than 0.001 mm, the heat shielding effect is insignificant, and if it is 0.5 mm or more, it is not preferable because it is not economical.

먼저, 도7에 나타낸 것과 같이, 알루미늄필름(210)의 일면에 난연재도포액(220)인 팽창흑연도포액(221)을 소정 두께로 도포 또는 분사한 후 거기에 다른 또 하나의 알루미늄필름(210)을 융착함으로써 시트형태피복체(200)를 형성하는 경우를 설명한다.First, as shown in FIG. 7 , an expanded graphite coating solution 221 , which is a flame retardant coating solution 220 , is applied or sprayed to a predetermined thickness on one surface of the aluminum film 210 , and then another aluminum film 210 is applied thereto. ), a case in which the sheet-like covering body 200 is formed by fusion bonding will be described.

상기 난연재도포액(220)은, 팽창성 흑연입자(expandable graphite)를 도료에 첨가하여 제조한 팽창흑연도포액(221)이 사용된다.As the flame retardant coating solution 220, the expanded graphite coating solution 221 prepared by adding expandable graphite particles to the paint is used.

상기 팽창성 흑연입자란, 층상 구조로 되어 있어 층상의 사이에 원자나 작은 분자를 집어넣을 수가 있는데, 이 층상의 사이에 황이나 질소화합물을 넣고 열을 가하면 그 흑연입자가 수백배 팽창하게 되는 흑연입자를 말한다.The expandable graphite particles have a layered structure, and atoms or small molecules can be inserted between the layers. When a sulfur or nitrogen compound is put between the layers and heat is applied, the graphite particles expand hundreds of times. say

상기 팽창성 흑연입자의 직경은 0.001mm 이상 0.5mm미만의 입자크기를 가지는 것이 바람직하다.The diameter of the expandable graphite particles preferably has a particle size of 0.001 mm or more and less than 0.5 mm.

상기 팽창성 흑연입자는 인상흑연(천연흑연)을 팽창시키는 것이므로 입자가 지나치게 작을 경우 팽창배수가 낮아진다.Since the expandable graphite particles expand the impression graphite (natural graphite), when the particles are too small, the expansion coefficient is lowered.

상기 팽창성 흑연입자의 직경 크기가 0.001mm 미만인 경우에는 팽창효과가 미미하여 차열효과가 적었으며, 상기 팽창성 흑연입자의 직경 크기가 0.5mm이상인 경우에는 팽창효과는 좋으나 경제성이 떨어지는 단점이 있었다.When the diameter size of the expandable graphite particles is less than 0.001 mm, the expansion effect is insignificant and the heat shielding effect is small, and when the diameter size of the expandable graphite particles is 0.5 mm or more, the expansion effect is good, but economical efficiency is poor.

또한, 상기 도료는 통상의 바인더를 사용하며, 상기 도료에 팽창성 흑연입자(expandable graphite)를 첨가 혼합하여 팽창흑연도포액(221)을 제조하게 된다.In addition, the paint uses a conventional binder, and expandable graphite particles (expandable graphite) are added and mixed to the paint to prepare an expanded graphite coating solution 221 .

상기 팽창흑연도포액(221)은, 자소성으로 인해 화재발생시 침투된 화염에 의해 먼저 산화된 후, 도10에 나타낸 것과 같이, 타고 남은 잔재에 의해 차염층(222)을 형성하게 된다.The expanded graphite coating liquid 221 is first oxidized by the flame that has penetrated when a fire occurs due to self-firing, and then, as shown in FIG. 10, a flame-blocking layer 222 is formed by the remaining burnt residue.

따라서, 상기 알루미늄필름(210)의 일면에 난연제 도포액인 팽창흑연도포액(221)을 소정 두께로 도포 또는 분사한 후 거기에 다른 또 하나의 알루미늄필름(210)을 융착하여 형성한 시트형태피복체(200)는, 화재발생시 상기 팽창흑연도포액(221)이 그 자소성으로 인해 침투된 화염에 의해 먼저 산화된 후, 도10에 나타낸 것과 같이, 타고 남은 잔재에 의해 차염층(222)을 형성하게 됨으로써 화염이 더이상 투과하기 어려운 환경을 형성하게 되는데, 이로써 외부로부터 침투되는 화염이 복합단열재의 내부 속재에 전달되는 속도를 지연시키게 되어 내부 속재가 발화되어 유독가스를 내뿜기 전에 사람들이 먼저 안전하게 대피할 수 있는 초기대피시간을 확보하여 화재안전성을 향상시켜 줄 수 있게 되는 것이다.Therefore, after coating or spraying the expanded graphite coating liquid 221, which is a flame retardant coating liquid, to a predetermined thickness on one surface of the aluminum film 210, another aluminum film 210 is fused thereto to form a sheet-like coating. In the case of a fire, the expanded graphite coating liquid 221 is first oxidized by the flame that has penetrated due to its self-extinguishing properties, and then, as shown in FIG. This creates an environment in which flames are no longer permeable. This delays the speed at which flames penetrating from the outside are transmitted to the inner inner material of the composite insulation material, so people can safely evacuate before the inner inner material ignites and emits toxic gas. It is possible to improve the fire safety by securing the initial evacuation time.

다음, 도8에 나타낸 것과 같이, 시트형태의 난연재시트(230) 양면에 알루미늄필름(210)을 융착하여 시트형태피복체(200)를 형성하는 경우를 설명한다.Next, as shown in FIG. 8 , a case in which the sheet-type covering body 200 is formed by fusing the aluminum film 210 on both sides of the sheet-type flame retardant sheet 230 will be described.

상기와 같이 시트형태 난연재시트(230) 양면에 알루미늄필름(210)을 융착하여 시트형태피복체(200)를 형성하는 경우에는, 알루미늄필름(210)의 난연성에 시트형태 난연재시트(230)의 난연성이 더해져서 시트형태피복체(200)의 차열성을 더욱 높인 것이므로, 화재발생시 화염이 투과될 수 있는 시간을 지연시켜 복합단열보드의 내부 속재가 외부 화염에 의해 발화되어 유독가스를 방출하기 전에 사람들이 안전하게 대피할 수 있는 초기대피시간을 확보할 수 있게 된다.In the case of forming the sheet-type covering 200 by fusing the aluminum film 210 on both sides of the sheet-type flame retardant sheet 230 as described above, the flame retardancy of the sheet-type flame-retardant sheet 230 to the flame retardancy of the aluminum film 210 Since this is added to further increase the heat shielding properties of the sheet-type covering body 200, it delays the time that the flame can be transmitted in the event of a fire, so that the internal material of the composite insulation board is ignited by the external flame to release toxic gas. It is possible to secure the initial evacuation time for safe evacuation.

상기 시트형태 난연재시트(230)는, 시트형태의 글래스울시트(231), 시트형태의 암면시트(232) 또는 시트형태의 부직포시트(233)와 같은 시트형태 난연재시트(230) 중 선택되는 어느 하나일 수 있다.The sheet type flame retardant sheet 230 is a sheet type flame retardant sheet 230, such as a sheet type glass wool sheet 231, a sheet type rock wool sheet 232, or a sheet type nonwoven sheet 233. can be one

상기 시트형태 난연재시트(230)의 두께는 0.2mm이상 3mm미만이면 무난하다. If the thickness of the sheet-shaped flame retardant sheet 230 is 0.2 mm or more and less than 3 mm, it is safe.

상기 시트형태의 난연재시트(230)의 두께가 0.2mm미만일 때에는 차열효과가 미미하였고, 상기 시트형태의 난연재시트(230)의 두께가 3mm이상일 경우에는 경제성이 떨어지는 단점이 있었다.When the thickness of the sheet-shaped flame retardant sheet 230 was less than 0.2 mm, the heat shielding effect was insignificant, and when the thickness of the sheet-shaped flame retardant sheet 230 was 3 mm or more, economic efficiency was inferior.

먼저, 상기 시트형태의 글라스울시트(231)는, 규사, 알루미나, 석회, 마그네시아, 붕산 등의 유리 원료를 고온에서 용융한 후 고속 회전력을 이용해 섬유화 화여 일정 형태로 만든 무기질의 인조 광물 섬유단열재로써, 고열에서는 용융되나 불이 붙지는 않고 유독가스를 발생시키지 않아 불연단열재로 환영을 받고 있다.First, the sheet-shaped glass wool sheet 231 is an inorganic artificial mineral fiber insulating material made by melting glass raw materials such as silica sand, alumina, lime, magnesia, boric acid, etc. at a high temperature and then forming a fiber using high-speed rotational force. , it melts at high temperature but does not catch fire and does not generate toxic gas, so it is welcomed as a non-combustible insulation material.

따라서, 시트형태의 글라스울시트(231) 양면에 알루미늄필름(210)을 융착하여 형성한 시트형태피복체(200)는, 알루미늄필름(210)의 난연성과 시트형태의 글라스울시트(231)의 난연성이 더해져 시트형태피복체(200)의 차열성을 더욱 높인 것이므로, 화재발생시 화염이 투과될 수 있는 시간을 지연시켜 복합단열보드의 내부 속재가 발화되어 유독가스를 방출하기 전에 사람들이 먼저 안전하게 대피할 수 있는 초기대피시간을 확보해 줄 수 있게 되는 것이다.Therefore, the sheet-like covering body 200 formed by fusing the aluminum film 210 on both sides of the sheet-like glass wool sheet 231 is the flame retardant of the aluminum film 210 and the sheet-like glass wool sheet 231. Since the heat shielding property of the sheet-like covering body 200 is further increased by adding flame retardancy, it delays the time that the flame can be transmitted in the event of a fire, so that people can safely evacuate before the internal material of the composite insulation board is ignited and toxic gas is emitted. It is possible to secure the initial evacuation time that can be done.

다음, 상기 시트형태의 암면시트(232, rock wool)는, 석회, 규산을 주성분으로 하는 내열성 광물을 용융하여 섬유화 한 것으로 물리적 성질이나 특성은 유리면과 거의 같다.Next, the sheet-shaped rock wool sheet (232, rock wool) is a fiber formed by melting a heat-resistant mineral containing lime and silicic acid as a main component, and has almost the same physical properties and characteristics as glass wool.

상기 시트형태의 암면시트(232)는, 암석(岩石)을 소재로 하여 인공으로 제조한 것이므로 내열성이 높은 광물 섬유이다. Since the rock wool sheet 232 in the sheet form is artificially manufactured using rock as a material, it is a mineral fiber with high heat resistance.

상기 시트형태의 암면시트(232)는 불연성, 경량성, 단열성, 흡음성, 내구성의 특징을 갖춰 건축 단열재 및 방화, 내화 재료로서 널리 사용되고 있다.The rock wool sheet 232 in the form of a sheet has characteristics of non-combustibility, light weight, heat insulation, sound absorption, and durability, and is widely used as a building insulation material, fire prevention, and fire resistance material.

따라서, 시트형태의 암면시트(232) 양면에 알루미늄필름(210)을 융착하여 형성한 시트형태피복체(200)는, 알루미늄필름(210)의 난연성과 상기 시트형태의 암면시트(232)의 난연성이 더해져 시트형태피복체(200)의 차열성을 더욱 높인 것이므로, 화재발생시 화염이 투과될 수 있는 시간을 지연시켜 복합단열보드의 내부 속재가 발화되어 유독가스를 방출하기 전에 사람들이 먼저 안전하게 대피할 수 있는 초기대피시간을 확보해 줄 수 있게 되는 것이다.Therefore, the sheet-type covering body 200 formed by fusing the aluminum film 210 on both sides of the sheet-shaped rock wool sheet 232 is the flame retardancy of the aluminum film 210 and the flame retardancy of the sheet-type rock wool sheet 232 . Since this is added to further enhance the heat shielding properties of the sheet-type covering body 200, it delays the time that the flame can be transmitted in case of a fire, so that people can safely evacuate before the internal material of the composite insulation board is ignited and toxic gas is emitted. It is possible to secure an initial evacuation time that is possible.

또한, 상기 시트형태의 부직포시트(233)는, 화염에 노출되었을 경우에도 불이 붙지 않아 유독가스를 생성하지 않는 불연성의 시트형태의 부직포시트(233)가 사용된다.In addition, the non-woven fabric sheet 233 in the form of a sheet is used as a non-woven sheet 233 in the form of a non-combustible sheet that does not catch fire even when exposed to a flame and does not generate a toxic gas.

따라서, 상기 시트형태의 부직포시트(233) 양면에 알루미늄필름(210)을 융착하여 형성한 시트형태피복체(200)는, 알루미늄필름(210)의 난연성과 상기 시트형태의 부직포시트(233)의 난연성이 더해져 상기 시트형태피복체(200)의 차열성을 더욱 높인 것이므로, 화재발생시 화염이 투과될 수 있는 시간을 지연시켜 복합단열보드의 내부 속재가 발화되어 유독가스를 방출하기 전에 사람들이 먼저 안전하게 대피할 수 있는 초기대피시간을 확보해 줄 수 있게 되는 것이다.Therefore, the sheet-type covering body 200 formed by fusion-bonding the aluminum film 210 on both sides of the sheet-type non-woven sheet 233 is the flame retardancy of the aluminum film 210 and the non-woven fabric sheet 233 of the sheet form. Since the heat shielding property of the sheet-like covering body 200 is further improved by adding flame retardancy, it delays the time that the flame can be transmitted in the event of a fire, so that the internal material of the composite insulation board is ignited and people can safely first before emitting toxic gas. It is possible to secure the initial evacuation time for evacuation.

상기와 같이 형성되는 시트형태피복체(200)는, 두께가 얇아 건축물의 실내공간을 잠식하지 않으면서도, 단열보드재(100)의 차열성을 강화시켜 준다.The sheet-like covering body 200 formed as described above is thin and does not encroach on the indoor space of the building, and strengthens the heat shielding properties of the insulation board material 100 .

또한, 상기와 같이 형성되는 시트형태피복체(200)는, 기본적으로 유연하여 시공성이 우수할 뿐더러, 화염이 관통하기 매우 어려워 화재발생시 사람들이 먼저 화염과 유독가스로부터 안전하게 대피할 수 있는 초기대피시간을 확보하는데 매우 유용하게 된다.In addition, the sheet-like covering body 200 formed as described above is basically flexible and has excellent workability, and the flame is very difficult to penetrate, so in the event of a fire, people can first safely evacuate from the flame and toxic gas. It is very useful to obtain

위와 같이 형성된 시트형태피복체(200)의 강도를 높여주어야 하는 경우에는 보강재로써 필름층(PET, PP, OPP중 선택되는 어느 하나로 된 필름층, 240)을 소정 두께로 더 추가하여 구성하면 될 것이다. When it is necessary to increase the strength of the sheet-like covering body 200 formed as above, a film layer 240 made of any one selected from PET, PP, and OPP as a reinforcing material may be further added to a predetermined thickness. .

도9는 상기에서 설명한 알루미늄필름(210)의 일면에 난연재 도포액인 팽창흑연도포액(221)을 소정 두께로 도포 또는 분사한 후 또 다른 알루미늄필름(210)을 융착하여 형성한 시트형태피복체(200)를, 단열보드재(100)의 양면에 융착하여 형성한 외부피복의 차열성이 강화되어 화재안전성이 향상된 복합단열보드(2)를 도시한 도면이고, 도10은, 도9에 도시한 외부피복의 차열성이 강화되어 화재안전성이 향상된 복합단열보드(2)의 외부피복체에 화염이 전파되어 외부 시트형태피복체(200)가 산화된 경우를 도시한 도면이다.9 is a sheet-like coating body formed by applying or spraying an expanded graphite coating solution 221, which is a flame retardant coating solution, to a predetermined thickness on one surface of the aluminum film 210 described above, and then fusion-bonding another aluminum film 210. 200, is a view showing a composite insulation board 2 with improved fire safety by strengthening the heat shielding properties of the outer coating formed by fusion on both sides of the insulation board 100, and FIG. 10 is shown in FIG. It is a view showing a case in which the outer sheet-type covering body 200 is oxidized because the flame propagates to the outer covering of the composite insulation board 2 with improved fire safety by strengthening the heat shielding property of one outer covering.

도9 및 도10으로부터 알 수 있는 것과 같이, 알루미늄필름(210)의 일면에 난연재 도포액인 팽창흑연도포액(221)을 소정 두께로 도포 또는 분사한 후 또 다른 알루미늄필름(210)을 융착하여 형성한 시트형태피복체(200)를, 단열보드재(100)의 양면에 융착하여 형성한 외부피복의 차열성이 강화되어 화재안전성이 향상된 복합단열보드(2)는, 화재발생시 상기 알루미늄필름(210)의 일면에 코팅된 플라스틱 코팅제(211)가 연소하며 부풀어올라, 도10에 나타낸 것과 같이, 소정폭의 공기층(212)을 형성하여 단열층을 이루게 된다.As can be seen from FIGS. 9 and 10 , an expanded graphite coating liquid 221 , which is a flame retardant coating liquid, is applied or sprayed to a predetermined thickness on one surface of the aluminum film 210 , and then another aluminum film 210 is fused to The composite insulation board 2 with improved fire safety by strengthening the heat shielding properties of the outer coating formed by fusing the formed sheet-type coating 200 on both sides of the insulation board material 100, the aluminum film ( The plastic coating agent 211 coated on one surface of the 210 burns and swells, and as shown in FIG. 10 , an air layer 212 of a predetermined width is formed to form a heat insulating layer.

상기 공기층(212)은, 화재 발생시 화염의 전파를 지연시켜 사람들이 화염과 유독가스로부터 먼저 대피할 수 있도록 초기대피시간을 확보하는데 일조하게 된다.The air layer 212 helps to secure the initial evacuation time so that people can first evacuate from the flame and toxic gas by delaying the propagation of the flame when a fire occurs.

따라서 상기 플라스틱 코팅제(211)가 일면에 코팅된 알루미늄필름(210)은, 복수 내지 다수겹을 융착하여 사용할 때 화염 전파 억지 효과는 더욱 커지게 될 것이다.Accordingly, when the plastic coating agent 211 is coated on one surface of the aluminum film 210 and used by fusion bonding a plurality of layers, the flame propagation inhibiting effect will be further increased.

즉, 상기와 같이 형성된 시트형태피복체(200)는, 플라스틱 코팅제(211)가 산화되어 공기층(212)을 형성함과 동시에, 도10에 나타낸 것과 같이, 팽창흑연도포액(221)이 산화되어 타고 남은 잔재에 의해 차염층(222)을 형성하게 되므로 화염이 관통하기 매우 어려워 화재발생시 사람들이 먼저 화염과 유독가스로부터 안전하게 대피할 수 있는 초기대피시간을 확보하는데 매우 유용하게 되는 것이다.That is, in the sheet-like coating body 200 formed as described above, the plastic coating agent 211 is oxidized to form the air layer 212, and, as shown in FIG. 10, the expanded graphite coating solution 221 is oxidized. Since the flame-shielding layer 222 is formed by the burnt residue, it is very difficult for the flame to penetrate, so it is very useful to secure an initial evacuation time for people to safely evacuate from the flame and toxic gas in the event of a fire.

3. 단열보드재와 시트형태피복체 융착단계(S3)3. Insulation board material and sheet-type coating material fusion step (S3)

상기와 같이 형성된 본발명의 외부피복의 차열성이 강화되어 화재안전성이 향상된 복합단열보드(2)는, 화재가 발생하여 화염이 소정온도에 이르게 될 경우 팽창흑연 도포액(221)이 먼저 연소된 후 팽창하여 두텁고 단단한 차염층(222)을 형성하여 800℃이상의 화염이라도 투과되기 어려운 여건을 형성하게 되므로 외부로부터 침투되는 화염이 내부 속재에 전달되는 속도를 지연시켜 내부 속재가 발화되어 유독가스를 내뿜기 전에 사람들이 먼저 안전하게 대피할 수 있는 초기대피시간을 확보하여 유독가스로부터 인명피해를 막아줄 수 있게 되는 것이다.Composite insulation board 2 with improved fire safety by strengthening the heat shielding properties of the outer coating of the present invention formed as described above, when the flame reaches a predetermined temperature due to a fire, the expanded graphite coating liquid 221 is first burned. It then expands to form a thick and hard flame-shielding layer 222, which creates a condition where even flames over 800°C are difficult to penetrate. It will be possible to secure an initial evacuation time for people to evacuate safely first, thereby preventing human casualties from toxic gases.
