Description
본 고안은 내화패널에 관한 것으로서, 보다 상세하게는 내부부재의 넓은 외측양면에 철판을 마련하고 난연섬유를 열간에서 압축 성형하거나 니들펀칭방법으로 생산한 고밀도의 섬유보드인 외부부재를 마련함으로써 깨지지 않고 비교적 가벼우며, 철판에 의해 차음, 단열 및 강도가 향상되는 내화패널에 관한 것이다.The present invention relates to a fireproof panel, and more particularly, it is not broken by providing an iron plate on a wide outer side of an inner member and providing an outer member, which is a high-density fiber board produced by hot-molding flame retardant fibers or by needle punching. It is relatively light and relates to a fireproof panel in which sound insulation, heat insulation and strength are improved by an iron plate.
일반적으로, 실내의 천장이나 벽면에 시공하는 것이 건축자재의 하나인 보드이고 실내를 구획하는 것이 패널이다. 이러한 보드나 패널은 재질에 따라 분류하거나 기능에 따라 분류하는데, 무수히 많고 다양하다. 현행 건축법 시행령 제61조에 해당하는 건축물의 경우, 거의 모든 내부 마감재료를 불연, 준불연, 난연재료로 하도록 규정하고 있고, 건축물의 내장재료 및 구조의 난연시험방법인 KS F 2271에 합격한 경우에 한하여 사용하도록 한정하고 있다.In general, it is a board that is one of the building materials to be installed on the ceiling or wall of the room, and the panel is partitioning the room. These boards and panels are classified by material or by function, which are numerous and varied. In the case of buildings under Article 61 of the Enforcement Decree of the current Building Act, almost all internal finishing materials are required to be non-flammable, semi-non-flammable, and flame-retardant materials.In case of passing KS F 2271, a flame retardant test method for the interior materials and structures of buildings. It is limited to use only.
이러한 기술과 관련된 종래의 내화패널은, 도 1에 나타낸 바와 같이, 소정두께의 유리섬유(7)가 마련되고 이 유리섬유(7)의 양면에 적어도 2개 층으로 방화석고보드(8a,8b)가 마련되어 있으며, 상기 유리섬유(7)의 한쪽에 차음을 위한 공간부(9)가 선택적으로 형성된 것이었다.In the conventional fireproof panel related to this technique, as shown in Fig. 1, a fireproof gypsum board 8a, 8b is provided with at least two layers on both sides of a glass fiber 7 having a predetermined thickness. Was provided, and a space 9 for sound insulation was selectively formed on one side of the glass fiber 7.
상기와 같이 구성된 종래의 내화패널에 있어서는, 패널의 전체적인 두께가 적어도 100∼165㎜로 마련되므로 패널이 너무 두껍고 무거울 뿐만 아니라 외측의 방화석고보드(8a,8b)의 재질특성상 취급시 약간의 충격에도 모서리부분이 깨지기 쉬운 것이었다. 특히, 건축물 실내의 내벽에 시공하였을 때 점유공간을 많이 차지하여 실내면적이 줄어든다는 문제점이 있었다.In the conventional fireproof panel configured as described above, since the overall thickness of the panel is provided at least 100 to 165 mm, the panel is not only too thick and heavy, but also has a slight impact when handled due to the material properties of the outer fireproof gypsum boards 8a and 8b. The edges were fragile. In particular, when the construction on the inner wall of the building occupies a lot of occupied space has a problem that the indoor area is reduced.
또한, 공개특허공보 공개번호 특2003-22916호의 건축용 차음 및 내화판넬은, 종이파이프가 함입된 발포플라스틱, 이 발포플라스틱의 양면에 각각 차음시트, 경량내화판재 및 표면마감재가 차례로 적층되어 이루어진 것이었다.In addition, the sound insulation and fireproof panel for building of Unexamined-Japanese-Patent No. 2003-22916 consisted of the foamed plastic in which the paper pipe was embedded, and the sound insulation sheet, the lightweight fireproof board material, and the surface finishing material were laminated | stacked in order on both sides of this foamed plastics, respectively.
상기와 같은 공개특허공보에 있어서는, 보다 효과적인 차음을 위해 알루미늄포일의 차음시트를 사용하고 전체적인 내화판넬의 두께를 비교적 얇으면서 경량으로 마련할 수 있다는 장점이 있으나, 차음시트가 알루미늄 포일과 그 외표면에 종이가 부착된 것이고 표면마감재 또한 종이로 마련된 것이므로 융점 내지 점화온도가 낮아 내화패널엔 적합하지 않고 경량내화판재가 펄라이트로서 재질특성상 취급시 약간의 충격에도 모서리부분이 깨지기 쉽다는 문제점이 있었다.In the above-described Patent Publication, there is an advantage that the sound insulation sheet of aluminum foil is used for more effective sound insulation, and the overall fireproof panel thickness can be provided with a relatively thin thickness, but the sound insulation sheet is made of aluminum foil and its outer surface. Since the paper is attached to the surface finisher is also made of paper, the melting point or the ignition temperature is low, so it is not suitable for the refractory panel, and the lightweight refractory board material is pearlite.
본 고안의 목적은 상기와 같은 종래의 제반 문제점을 해결하기 위하여 연구 개발한 것으로서, 난연 기능을 갖는 저밀도의 내부부재 양면에 얇은 철판이 부착되고 난연섬유를 열간에서 압축 성형하여 융착시키거나 니들펀칭방법으로 생산한 고밀도의 섬유 보드인 외부부재를 마련함으로써 패널외측표면의 4변 모서리가 깨지지 않음은 물론 비교적 가벼우며, 특히 내/외부부재 사이에 개재된 철판으로 인해 차음, 단열 및 강도가 향상되도록 한 내화패널을 제공하는데 있다.An object of the present invention is a research and development in order to solve the conventional problems as described above, a thin iron plate is attached to both sides of a low-density inner member having a flame-retardant function and hot-compression molding the flame-retardant fibers in the hot welding or needle punching method By providing the outer member, which is a high-density fiber board produced by the product, the four sides of the outer surface of the panel are not broken, and are relatively light. In particular, the steel plate interposed between the inner and outer members improves sound insulation, insulation, and strength. To provide a fireproof panel.
또한, 본 고안의 다른 목적은 패널의 측면마감부재는 물론 이음부재를 고밀도의 섬유 보드인 외부부재와 동일재료로 마련함으로써 패널의 시공에 따른 모든 소재가 난연재료로 이루어질 수 있고 이로 인하여 확실한 내화효과를 얻을 수 있도록 한 내화패널을 제공하는데 있다.In addition, the other object of the present invention is to provide the side member of the panel as well as the joint member of the same material as the outer member of the high-density fiber board, all the materials according to the construction of the panel can be made of flame-retardant material and thereby a sure fire resistance effect To provide a fireproof panel to obtain.

이하, 본 고안의 내화패널을 첨부된 도면에 의거하여 상세하게 설명하고자 한다.Hereinafter, the fireproof panel of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 고안에 따른 내화패널을 나타낸 사시도면이고, 도 3은 본 고안의 내화패널을 연결 시공한 이음부분의 단면도이다.Figure 2 is a perspective view showing a fireproof panel according to the present invention, Figure 3 is a cross-sectional view of the joint portion connecting the fireproof panel of the present invention.
도면에 나타낸 바와 같이, 내부에 난연등급 이상의 섬유보드로 된 저밀도의 내부부재(10)가 마련되고, 이 내부부재(10)의 넓은 양쪽표면에 얇은 철판(12)이 마련되어있으며, 이 얇은 철판(12)의 넓은 외측표면에는 난연섬유를 열간에서 프레스를 이용하여 압축 성형하여 융착시키거나 니들펀칭방법으로 생산한 고밀도의 외부부재(14)가 마련되어 있고 상기 철판(12)과 외부부재(14)는 내부부재(10)에 접착제로 접착할 때, 접착제의 응고시간이라든가 접착제의 응고후 박리에 의한 들뜸을 방지함과 아울러 패널의 강도유지를 위해 외측표면에서 소정간격의 위치마다 못(15)이나 철침이 피어싱(piercing)되어 있다.As shown in the drawing, a low density inner member 10 made of a fiber board having a flame retardant grade or higher is provided therein, and thin iron plates 12 are provided on the wide both surfaces of the inner member 10, and the thin iron plate ( On the wide outer surface of 12), a high-density outer member 14 produced by compression molding the flame-retardant fibers by hot press using a press or a needle punching method is provided, and the iron plate 12 and the outer member 14 are When adhering to the inner member 10 with an adhesive, it is possible to prevent the lifting due to the solidification time of the adhesive or the peeling after the solidification of the adhesive and to maintain the strength of the panel. This is piercing.
상기 내부부재(10)는 섬유보드인 내부부재(10)를 그 두께로 절단하여 접착제에 의해 접착한 것이며, 상기 외부부재(14) 사이의 내부부재(10) 양단에 고밀도의 섬유보드인 외부부재(14)와 동일재료로 된 측면마감부재(16)가 마련된다. 이때, 외부부재(10)의 양쪽에는 서로 이웃하는 내화패널을 연속하여 시공할 때 이음부재(18)를 끼워 넣을 수 있는 공간(홈)이 형성될 수 있다.The inner member 10 is an inner member 10, which is a fiber board, is cut to its thickness and bonded by an adhesive, and an outer member that is a high density fiber board at both ends of the inner member 10 between the outer members 14. A side closure member 16 made of the same material as 14 is provided. At this time, both sides of the outer member 10 may be provided with a space (groove) for inserting the joint member 18 when the neighboring fireproof panels are continuously installed.
또한, 상기 내부부재(10)는 그 두께로 저밀도의 섬유보드를 절단하여 패널 전체의 폭에 상당하도록 부착한 것으로 마련된다. 이때, 내부부재(10)의 접착선을 내화패널의 두께방향으로 접착하는 이유는 섬유보드의 구조적인 특성상 그 두께방향보다 그 직각방향(접착선 방향)이 강도가 크기 때문이다.In addition, the inner member 10 is provided by cutting the fiber board of low density to its thickness and attached to correspond to the width of the entire panel. At this time, the reason for bonding the adhesive line of the inner member 10 in the thickness direction of the fireproof panel is because the strength of the right angle direction (bonding line direction) is greater than the thickness direction due to the structural characteristics of the fiber board.
상기 이음부재(18)는 서로 이웃하는 내화패널의 공간에 채워지도록 고밀도의 섬유보드인 외부부재(14)를 절단하여 부착한 것으로 마련된다. 이때, 이음부재(18)의 접착선이 내화패널의 두께방향으로 이뤄짐이 바람직하다. 그 이유는 상기 내부부재(10)를 절단하여 두께방향으로 접착하는 이유와 같다.The joint member 18 is provided by cutting and attaching the outer member 14, which is a high-density fiber board, to be filled in the spaces of the neighboring fireproof panels. At this time, it is preferable that the adhesive line of the joint member 18 is made in the thickness direction of the fireproof panel. The reason is the same as that of cutting the inner member 10 in the thickness direction.
상기 내부부재(10) 및 외부부재(14)에 사용된 난연섬유는 폴리에스터수지,폴리프로필렌수지, 폴리에틸렌수지, 복합 폴리프로필렌수지 및 복합 폴리에틸렌수지 등으로부터 추출된 하나의 합성수지 섬유를 마련하고 이 합성수지섬유를 수용성의 무기질 난연제로 난연 처리하여 난연섬유를 마련한 것이다.The flame retardant fibers used for the inner member 10 and the outer member 14 are provided with one synthetic resin fiber extracted from a polyester resin, a polypropylene resin, a polyethylene resin, a composite polypropylene resin, a composite polyethylene resin, and the like. Flame retardant treatment of the fiber with a water-soluble inorganic flame retardant to prepare a flame retardant fiber.
이렇게 난연 처리후, 프레스의 금형에 넣어 단위면적(㎠)당 3∼6㎏압력으로 230∼270℃에서 60∼120초 동안 유지시켜 압축 성형하여 융착시키고, 단위면적(㎠) 당 3㎏정도의 압력에서 50초 이상의 냉각시간이 지난 후 꺼냄으로써 고밀도의 섬유보드를 얻는다.After the flame-retardant treatment, it was put into a mold of press and maintained at 230-270 ° C. for 60 to 120 seconds at a pressure of 3 to 6 kg per unit area (cm 2), followed by compression molding and fusion, and about 3 kg per unit area (cm 2). A high density fiberboard is obtained by taking out after 50 seconds or more of cooling time in pressure.
상기한 섬유보드의 압축성형에서 압력이 3㎏/㎠이하이고 온도가 230℃이하이고 시간이 60초 이하이면 난연섬유의 융착이 제대로 이뤄지지 않아 강도가 약하며, 이와 반대로 압력이 6㎏/㎠이상이고 온도가 270℃이상이고 시간이 120초 이상이 되면 융착 섬유질의 깨짐 현상이 발생되어 충격에 취약함은 물론 패널로서의 조건을 얻을 수 없다는 문제점이 있다.In the compression molding of the fiber board, if the pressure is less than 3㎏ / ㎠, the temperature is less than 230 ℃ and the time is less than 60 seconds, the fusion of the flame retardant fiber is not properly achieved, the strength is weak, on the contrary the pressure is more than 6㎏ / ㎠ If the temperature is more than 270 ℃ and the time is more than 120 seconds, the phenomenon of breaking of the fused fiber is generated, there is a problem in that it is not vulnerable to impact as well as a condition as a panel.
상기 합성수지섬유의 난연처리는 수용성의 무기질 난연제가 담긴 용기에 함침시켰다가 꺼내어 건조시키거나 스프레이 방식으로 분사 건조시키는 과정으로 이루어진다.The flame retardant treatment of the synthetic resin fiber is made by impregnating a container containing a water-soluble inorganic flame retardant is taken out to dry or spray-dried in a spray method.
상기 수용성의 무기질 난연제는 카르복시메틸 셀룰로오스나트륨(C.M.C) 50~55중량%, 제1인산나트륨 30~40중량%, 제1인산암모늄 15~25중량%의 혼합물 100g을 물 2ℓ에 용해시켜 용제를 조성하고 이 용제에 실리콘 400∼1200g를 넣어 교반하여 혼합용액을 만든 후 상기 혼합용액에 규산 소다용액 2000~3200g로 혼합한 혼합용액이다.The water-soluble inorganic flame retardant dissolve 100 g of a mixture of 50 to 55% by weight of sodium carboxymethyl cellulose (CMC), 30 to 40% by weight of sodium monophosphate, and 15 to 25% by weight of ammonium monophosphate in 2 liters of water to form a solvent. 400 to 1200 g of silicon was added to the solvent, followed by stirring to form a mixed solution. The mixed solution was mixed with 2000 to 3200 g of a soda silicate solution.
상기 규산 소다용액은 20℃에서의 밀도(Be') 52~54이며, 물불용분 0.2중량%이하, 산화나트륨(Na2O) 10~15중량%, 이산화규소(SiO2) 34~35중량%, 산화제이철(Fe2O3) 0.05중량%의 비율로 혼합된 현재 시판중인 액상 규산 소다 제2호를 사용한다. 여기에서 규산 소다용액은 제2호를 사용하는 것으로 설명하였으나 제1호나 제3호를 사용할 수 있음은 물론이다. 상기 규산 소다는 패널이 난연성 및 강성을 가질 수 있도록 하고, 카르복시메틸 셀룰로오스나트륨은 80℃이상의 온도에서는 셀룰로오스 막을 형성함으로써 물에 대하여 불용성이 되어 습기에 약한 규산 소다의 단점을 보완하는 작용을 한다.The soda silicate solution has a density (Be ') of 52 to 54 at 20 ° C, 0.2 wt% or less of water insoluble content, 10 to 15 wt% of sodium oxide (Na 2 O), and 34 to 35 weight of silicon dioxide (SiO 2 ) % Commercially available liquid sodium silicate No. 2 mixed at a ratio of 0.05% by weight of ferric oxide (Fe 2 O 3 ). Herein, the silicate soda solution is described as using No. 2, but No. 1 or No. 3 can be used. The soda silicate so that the panel can have a flame retardancy and rigidity, and the carboxymethyl cellulose sodium to form a cellulose film at a temperature of 80 ℃ or more serves to compensate for the disadvantage of soda silicate insoluble in water.
상기 제1인산암모늄은 난연기능을 부가시키며, 제1인산나트륨은 형태가 흐트러지는 것을 방지하는 강성보강작용을 한다. 또한, 실리콘은 난연성 뿐만 아니라 발수성이 있으며, 변성실리콘인 Polyvinyl Methyle Silicon Rubber로서 대체될 수 있다.The first ammonium phosphate adds flame retardant function, and the first sodium phosphate has a rigid reinforcing action to prevent the form from being disturbed. In addition, silicon is not only flame retardant but also water repellent, and may be replaced with polyvinyl methyl silicon silicon rubber.
상기와 같이 구성된 내화패널은, 서로 이웃하는 내화패널을 연속하여 시공할 때, 내화패널의 양단에 형성된 공간으로 이음부재(18)를 끼워 넣고, 이 이음부재(18)의 돌출부분이 서로 이웃하는 내화패널의 공간으로 삽입되어 서로 이웃하는 내화패널의 공간이 하나로 통합되도록 일직선으로 시공된 것이다.In the fireproof panel configured as described above, when continuously constructing fireproof panels adjacent to each other, the joint member 18 is inserted into a space formed at both ends of the fireproof panel, and the protruding portions of the joint member 18 are adjacent to each other. Inserted into the space of the fireproof panel is constructed in a straight line so that the spaces of the adjacent fireproof panels are integrated into one.
또한, 상기 이음부재(18)는 도 2 및 도 3과 같이, 고밀도의 섬유보드인 외부부재(10)를 절단하여 부착한 것으로 도시하고 설명하였으나 접착선이 없는 하나의 몸체, 일체로 마련하여도 무방하다.In addition, the joint member 18, as shown in Figure 2 and 3, cut and attached to the outer member 10, which is a high-density fiber board, but one body without an adhesive wire, even if provided as one It's okay.
이렇게 시공된 내화패널은, 외부부재(14)가 난연 등급이상으로 난연 처리된 것이므로 대략 1000℃에서 연소가 된다하더라도 철판(12)에 의해 단열되고 내부부재(10)로의 열 전달이 급격하게 저하된다. 이때, 내부부재(10)의 온도는 600℃정도로 무려 400℃가 떨어지므로 내화등급의 실내 인테리어에 적합한 것이다.Since the fireproof panel constructed as described above is flame retardant to the flame retardant grade or higher, even if it is burned at about 1000 ° C., it is insulated by the iron plate 12 and the heat transfer to the inner member 10 is rapidly reduced. . At this time, since the temperature of the inner member 10 is dropped to 400 ℃ to about 600 ℃ degree is suitable for interior interior of fireproof grade.
또한, 외부부재(14)가 난연섬유를 융착에 의해 압축 성형되거나 니들펀칭방법으로 생산된 것이므로 패널의 4변 모서리부분이 깨질 염려가 없는 것이다.In addition, since the outer member 14 is compression molded or produced by needle punching the flame retardant fibers, the four edges of the panel are not likely to be broken.
그리고, 본 고안의 내화패널은 100∼165㎜인 기존 내화패널의 두께에 비하여 대략 절반정도의 두께로 내화기능을 수행할 수 있으며, 이로 인하여 고층을 고려할 경우 건물의 실평수(면적)가 넓어지고 무게를 줄일 수 있는 것이다.In addition, the fireproof panel of the present invention can perform the fireproof function to about half the thickness of the existing fireproof panel thickness of 100 ~ 165㎜, and thus the actual floor area (area) of the building becomes wider and weight in consideration of the high floor. This can be reduced.
이상에서 살펴본 바와 같이, 본 고안의 내화패널은, 난연 기능을 갖는 저밀도의 내부부재 양면에 얇은 철판이 부착되고 난연섬유를 열간에서 압축 성형하여 융착시키거나 니들펀칭방법으로 생산한 고밀도의 섬유 보드인 외부부재를 마련함으로써 패널외측표면의 4변 모서리가 깨지지 않음은 물론 비교적 가벼우며, 특히 내/외부부재 사이에 개재된 철판으로 인해 차음, 단열 및 강도가 향상되는 유용한 것이다.As described above, the fireproof panel of the present invention is a high-density fiber board attached to both sides of a low-density inner member having a flame-retardant function, and a flame-retardant fiber is hot-pressed by compression molding or produced by a needle punching method. By providing the outer member, the four side edges of the outer surface of the panel are not broken, and are relatively light. Especially, the sound insulation, insulation, and strength are improved due to the steel plate interposed between the inner and outer members.
또한, 패널의 측면마감부재는 물론 이음부재를 고밀도의 섬유보드와 동일재료로 마련함으로써 패널의 시공에 따른 모든 소재가 난연소재로 이루어질 수 있고 이로 인하여 확실한 내화효과를 얻을 수 있는 유용한 것이다.In addition, by providing the side closure member of the panel as well as the joint member of the high density fiber board, all the materials according to the construction of the panel can be made of a flame retardant material, thereby making it possible to obtain a sure fire resistance effect.
