Description

친환경적인 내화패널{Environment friendly fireproof panel}Environment friendly fireproof panel {Environment friendly fireproof panel}

본 발명은 내화패널에 관한 것으로, 보다 상세하게는 내화성, 내구성, 방수성, 차음성, 단열성 및 시공성이 향상되고 친환경적인 내화패널에 관한 것이고, 특히 터널 및 지하차도의 환기시스템을 위한 풍도 슬래브에 바람직하게 적용될 수 있는 친환경적인 내화패널에 관한 것이다.More particularly, the present invention relates to a refractory panel having improved fire resistance, durability, waterproofness, sound insulation, heat insulation and workability, and is environmentally friendly, and particularly relates to a windshield slab for a tunnel and an underground driveway Friendly refractory panel that can be applied to the environment.

샌드위치 구조의 내화패널은 불연성의 한 쌍의 표면재 사이에 내화성을 가지는 심재를 삽입, 접착한 것으로 심재로는 글라스 울, 미네날 울 등 불연재료가 사용된다. 표면재로는 불연성의 소재로서 금속판, 크레드강판, 시멘트판, 세라믹판 등이 사용될 수 있다. 그러나 패널의 제조시 강도 유지를 위해 섬유 결을 수직으로 세우고 접착제를 이용한 접착 과정을 거치므로 이 과정에서 유기질 접착제를 사용하므로 불연성능이 다소 저하될 수 있고 강도확보를 위해 접착제의 양을 과다하게 사용하면 난연재료 급으로 품질이 하락할 수 있다는 단점이 있다. The sandwich panel fireproof panel is formed by inserting and bonding a fire resistant core material between a pair of non-flammable surface materials. Non-combustible materials such as glass wool and mineral wool are used as the core material. As the surface material, a metal plate, a crad steel plate, a cement plate, a ceramic plate, or the like may be used as a nonflammable material. However, in the manufacture of panels, the fiber grains are erected vertically and the adhesive process using adhesive is used. Therefore, organic adhesive is used in this process, so the non-combustibility may be lowered and the amount of adhesive is used excessively to secure the strength. The quality of the flame retardant material may deteriorate.

이러한 샌드위치 구조의 내화패널에서 심재로서 글라스 울이나 미네날 울 이외에 (a) 합성수지 발포층 중에 무기물질을 혼재시킨 것, (b) 무기발포체만으로 된 것 등이 사용되기도 한다. 그러나 (a)의 경우 합성수지 발포층에 개재한 무기물질이 표면재와 합성수지 발포층과의 접착강도를 저하시키는 문제가 있고, (b)의 경우 내화성은 뛰어나지만 기계적 강도(절곡, 절단, 충격) 등에 결함이 있고 동시에 패널 자체의 중량이 증가하여 취급하기가 어렵고 시공성이 나쁘다는 문제점이 있다. In such a sandwich structure fireproof panel, as the core material, (a) a mixture of inorganic materials in the synthetic resin foam layer, (b) only an inorganic foam, etc. may be used as a glass material or a mineral wool. However, in the case of (a), there is a problem that the inorganic material interposed in the synthetic resin foam layer lowers the adhesive strength between the surface material and the synthetic resin foam layer.In the case of (b), although the fire resistance is excellent, the mechanical strength (bending, cutting, impact), etc. At the same time, there is a problem in that the weight of the panel itself increases, making it difficult to handle and poor in workability.

상기한 종래 샌드위치 구조의 내화패널이 가지는 문제점을 해소하기 위한 것으로 대한민국 공개특허 제19930023166호(1999.04.01)가 제안되었다. 이 공개특허는 무기입자 형상물 및 무기섬유의 1종 이상의 방화재 등을 합성수지 발포층에 분포시킴으로써 내화성, 방화성을 향상시키며, 단열성을 가진 패널로서 표, 이면재와 심재와의 사이에 부직포를 개재시킴으로써 표, 이면재와 심재와의 접착력을 강화시키고 패널의 기계적 강도를 향상시킨 것이다.Korean Unexamined Patent Publication No. 19930023166 (1999.04.01) has been proposed for solving the problems of the fireproof panel of the conventional sandwich structure. This patent discloses that the fire resistant and fire resistant properties are improved by distributing at least one type of fire retardant such as inorganic particles and inorganic fibers in a synthetic resin foam layer, and a table having a heat insulating property and a nonwoven fabric interposed between a backing material and a core material. , The adhesion between the backing material and the core material is enhanced and the mechanical strength of the panel is improved. 그러나 이 공개특허 또한 패널의 중간층을 형성하는 심재로서 합성수지 발포층을 사용함으로써 환경에 유해하며 합성수지 발포층과 불연성의 소재로서 금속판, 크레드강판, 시멘트판, 세라믹판 등이 사용되는 표, 이면재와의 접착력을 향상시키기 위해 부가적으로 부직포를 필요로 한다는 단점이 있다.However, this publication also uses a synthetic resin foam layer as a core material for forming the middle layer of the panel, which is harmful to the environment, and the surface and backing material where metal sheets, crad steel plates, cement plates, ceramic plates, etc. are used as the synthetic resin foam layer and nonflammable material. There is a disadvantage that a nonwoven fabric is additionally required in order to improve the adhesive strength.

In the following the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings, but the embodiments presented are exemplary for a clear understanding of the present invention is not limited thereto.

도 1은 본 발명에 따른 내화패널을 나타낸 단면도이다.1 is a cross-sectional view showing a fireproof panel according to the present invention.

도 1에 도시된 바와 같이 본 발명에 따는 내화패널(10)은, 한 쌍의 불연성을 가지는 표면재(11)(11) 사이에 내화성을 가진 충진재를 채워 심재(12)를 구성한 것이다. As shown in FIG. 1, the fire resistant panel 10 according to the present invention is filled with a fire resistant filler between a pair of non-flammable surface materials 11 and 11 to form a core 12.

본 발명에서 표면재(11)를 구성하는 불연성의 소재는 산화마그네슘, 염화마그네슘, 플라이애쉬, 목분 및 진주암의 혼합물을 판재 형태로 압축 성형한 것으로, 바람직하게는 산화마그네슘 50중량부, 염화마그네슘 13중량부, 플라이애쉬 15중량부, 목분 18중량부 및 진주암 4중량부로 구성된다. The incombustible material constituting the surface member 11 in the present invention is a mixture of magnesium oxide, magnesium chloride, fly ash, wood powder and perlite, which is compression molded into a sheet form. Preferably, magnesium oxide 50 weight part, magnesium chloride 13 weight 15 parts by weight of fly ash, 18 parts by weight of wood powder and 4 parts by weight of perlite.

산화마그네슘(MgO)은 마그네슘과 산소의 화합물로 공기 중에서 물 및 이산화탄소를 흡수하며 흰색의 비결정성 가루이다. 염화마그네슘(MgCl2)은 무수물 외에 2,4,6,8,10,12 수화물 등이 있으나, 보통은 육수화물 MgCl2·6H2O로서 존재한다. 무수물은 무색의 결정성 분말로, 녹는점 712 ℃, 끓는점 1,412 ℃, 비중 2.325(25 ℃)이다. 흡습성이 강하고, 물·알코올에 잘 녹는다. 본 발명에서는 무수물을 이용하며 산화마그네슘을 섞어서 바인더를 구성한다. Magnesium oxide (MgO) is a compound of magnesium and oxygen that absorbs water and carbon dioxide in the air and is a white amorphous powder. Magnesium chloride (MgCl2) is not only anhydrate but also 2,4,6,8,10,12 hydrate, but usually exists as hexahydrate MgCl2 · 6H2O. The anhydrous substance is a colorless crystalline powder having a melting point of 712 캜, a boiling point of 1,412 캜, and a specific gravity of 2.325 (25 캜). Hygroscopicity is strong and melts well in water and alcohol. In the present invention, an anhydride is used and magnesium oxide is mixed to constitute a binder.

플라이애쉬란 화력발전소 등에서 미분탄을 연소했을 때 생기는 폐가스 속에 포함되어 있는 탄의 미립자를 집진기에 의하여 포집한 것을 말한다. 본 발명에서는 표면재의 강도의 증진, 수밀성, 내구성의 향상 및 건조수축을 감소시키기 위해 사용한다. 또한 패널 표면에 별도의 마감이 필요 없는 원활한 색상을 유지시킨다.Fly ash refers to the collection of fine particles of coal contained in the waste gas generated when burning pulverized coal in a coal-fired power plant. In the present invention, it is used to enhance the strength of the surface material, improve the watertightness, improve durability and reduce dry shrinkage. It also maintains a smooth color that does not require a separate finish on the panel surface.

목분은 40-100 mesh 정도로 곱게 갈은 목재 입자로서 본 발명에서는 바인더의 사용량을 저감시키면서 충진재로서 표면재의 강도 증기를 위해 사용된다. Wood flour is finely ground wood particles of about 40-100 mesh, and is used in the present invention for strength steam of the surface material as a filler while reducing the amount of binder used.

진주암은 유리질 유문암의 일종으로 구상의 균열이 뚜렷하며 유리질에 동심원 구조가 있고, 빛은 이 구조의 간섭에 의해서 진주광택을 내기 때문에 이 이름이 붙었다. 본 발명에서는 경량골재로 이용되었다.Pearlite is a type of glassy rhyolite, which has a distinct globular spherical shape, concentric circles in the glass, and is named because light emits pearlescent luster by the interference of this structure. In the present invention was used as a lightweight aggregate.

패널의 중간층을 형성하는 심재(12)로는 진주암(121) 입자 사이에 세람사이트(Ceramsite,122)가 불규칙적으로 분포된 혼합물을 사용한다. 바람직하게는 진주암 90중량부 및 세람사이트 10중량부로 구성되고 세람사이트는 진주암 입자보다 더 큰 입자 형상으로 되며 진주암 분말 사이에 불규칙적으로 분포된 형태가 된다. 본 발명에서 표면재는 산화마그네슘과 염화마그네슘의 혼합물로 구성되는 바인더를 가지므로 별도의 부착력 증진을 위한 소재, 예컨데 부직포 등을 필요로 하지 않고 심재로 사용되는 진주암과 세람사이트 혼합물 사이의 결합을 견고하게 할 수 있다. As the core 12 forming the middle layer of the panel, a mixture in which ceramsite 122 is irregularly distributed between the pearlite particles 121 is used. Preferably it is composed of 90 parts by weight of pearlite and 10 parts by weight of ceramsite and the ceramsite has a larger particle shape than the pearlite particles and is irregularly distributed between the pearlite powders. In the present invention, since the surface material has a binder composed of a mixture of magnesium oxide and magnesium chloride, it is not necessary to use a material for enhancing the adhesion strength, for example, a nonwoven fabric, and the bonding between the perene- can do.

이와 같이 구성되는 본 발명에 따른 내화패널은 염화마그네슘에 산화마그네슘을 섞어서 바인더를 만들고 이에 플라이애쉬, 목분 및 진주암을 혼합한 다음 압축 경화시켜 판재 형태의 표면재를 만들고, 그 위에 진주암 입자 사이에 세람사이트를 불규칙적으로 분포시킨 혼합물을 적층하고 다시 그 위에 표면재를 적층하여 일체로 경화시켜 제조된다. 즉, 본 발명에서는 유기 화합물을 일체 적용하지 않고 무기물로만 구성된 것으로서 친환경적이다. The refractory panel according to the present invention constituted as described above is prepared by mixing magnesium chloride and magnesium oxide to form a binder, mixing fly ash, wood powder and perlite, and then compressing and curing the surface material to form a sheet material. It is prepared by laminating a mixture of irregularly distributed and again laminating the surface material thereon to cure integrally. That is, the present invention is environmentally friendly because it is constituted only of an inorganic material without applying any organic compound.

도 2는 RABT 화재-온도 곡선에 의한 내화시험 결과 콘크리트 블록 내부의 온도 분포를 나타낸 것이다.  Figure 2 shows the temperature distribution inside the concrete block as a result of the fire test by the RABT fire-temperature curve.

본 발명에 따른 내화패널은 터널 및 지하차도의 환기시스템을 위한 풍도 슬래브에 적용되므로 터널 내의 화재에 대해 내화성능이 요구된다. 내화성능을 파악하기 위해 터널 내 화재를 대상으로 하는 강력한 화재이력곡선으로서 초기에 급격하게 온도가 증가하여 일정시간을 유지한 후 소화되는 터널 내 실제화재 과정을 가장 유사하게 모사하는 독일의 RABT(Richtlinien fur die Ausstanttung und den Betrieb von Stranbentunneln) 화재이력곡선을 사용하여 내화성능을 평가하였다. Since the refractory panel according to the present invention is applied to a wind-induced slab for a tunnel and an underground roadway ventilation system, fire resistance is required for a fire in a tunnel. This is a powerful fire history curve for fires in tunnels to understand the fire performance. The German RABT (Richtlinien) is the most similar to the actual fire process in tunnels which are rapidly extinguished and maintained for a certain period of time. fur die Ausstanttung und den Betrieb von Stranbentunneln) fire hysteresis curves were used to evaluate the fire performance.

시험체로는 하부면에 본 발명에 따른 내화패널(두께 20mm)이 설치된 철근콘크리트 패널(두께 230mm)로서 내부에는 PS강선이 매립되어 있다. 시험체 내부에는 총 7개의 열전대가 설치되었으며 내화패널과 콘크리트의 접촉면(t=0mm)에 4개, 그리고 내화패널과 콘크리트의 접촉면으로부터 25mm 위치(t=25mm)에 3개가 설치되었다.The test specimen was a reinforced concrete panel (thickness 230 mm) in which a fireproof panel (thickness: 20 mm) according to the present invention was installed on the lower surface, and a PS steel wire was embedded therein. A total of seven thermocouples were installed inside the specimens, four at the contact surface of the fireproof panel and concrete (t = 0mm), and three at the 25mm position (t = 25mm) from the contact surface of the fireproof panel and concrete.

시험결과 도 2에서 보듯이 콘크리트의 손상을 판단하는 위치인 t=0mm의 최대온도는 367℃로서 ITA(2004)에 따른 콘크리트의 손상 한계온도 380℃ 이하였으며, 철근의 손상을 판단하는 위치인 t=25mm 의 최대온도는 239℃로서 손상 한계온도인 250℃ 이하로 나타났다. 따라서 내화패널의 두께가 20mm인 콘크리트 블록 시험체는 RABT 화재시나리오 하에서 내화성능을 가진 것으로 나타났다. As a result of the test, as shown in FIG. 2, the maximum temperature of t = 0mm, which is the position at which the concrete is judged to be damaged, was 367 ° C. = 25mm was 239 ℃, which was below the damage limit temperature of 250 ℃. Therefore, the concrete block specimens with a thickness of 20 mm of the fireproof panel have fire resistance performance under the RABT fire scenario.
