Description
본 발명은 방화문 및 방화문 어셈블리에 관한 것으로, 더욱 상세하게는 내화성과 단열성 및 결로방지성능을 확보하면서도 제조비용을 절감한 방화문 및 방화문 어셈블리에 관한 것이다.The present invention relates to fire doors and fire door assemblies, and more specifically, to fire doors and fire door assemblies that reduce manufacturing costs while ensuring fire resistance, insulation, and condensation prevention performance.
사회 소득수준이 높아짐에 따라 안전문제의 가치가 높아지게 되었으며, 이러한 추세에 따라 고품질의 방화문의 수요도 늘고 있다. 최근 한 언론보도에 따르면 31개의 아파트 단지 주민들이 173개 방화문 성능을 시험하였으며, 그 결과 82% 141개가 불합격 판정을 받은 것으로 나타났다. 이에 격실 내부를 보호 할 수 있으면서 고기능성을 가지는 방화문 개발이 필요한 실정이다. As society's income level increases, the value of safety issues has increased, and in accordance with this trend, the demand for high-quality fire doors is also increasing. According to a recent media report, residents of 31 apartment complexes tested the performance of 173 fire doors, and as a result, 141 (82%) were judged to have failed. Accordingly, there is a need to develop fire doors that can protect the interior of the compartment and have high functionality.
정부 정책으로서, 대피공간은 화재시 상부층으로 연소 확대를 방지하고 피난을 위한 생존공간으로 사용된다는 점에서 안전 확보에 도움이 되지만 차열 방화문이 아닌 비차열방화문을 설치할 수 있도록 한 종래규정의 문제점이 부각되면서 차열 성능 기준에 대한 요구는 끊임없이 제기 되어 왔으며, 실제로 방재실험연구원의 대피공간 목업 테스트 결과 비차열 방화문을 설치한 경우 화재 발생 10분 후부터 격실 내부의 온도는 안전기준인 (미국 NFPA code) 60℃ 초과가 확인되었고, 25분후 100℃, 1시간 후에는 무려 170℃ 까지 온도가 치솟는 것으로 나타난 바 있다. 이에 최근 국토교통부는 아파트 대피공간에 설치되는 방화문의 성능 기준을 강화한 「건축물 피난, 방화구조 등의 기준에 관한 규칙」을 공표했고, 이에 따라 2016년 4월 5일 부터는 아파트 대피공간에 열 차단 성능이 30분 이상 되는 방화문을 반드시 설치해야 한다고 강제하고 있어 수요는 크게 증가할 것으로 전망된다.As a government policy, the evacuation space helps ensure safety in that it prevents the spread of combustion to the upper floors in the event of a fire and is used as a survival space for evacuation. However, problems with the existing regulations that allow installation of non-insulated fire doors rather than insulated fire doors are highlighted. As a result, demands for thermal insulation performance standards have been constantly raised, and in fact, according to the Disaster Prevention Research Institute's mock-up test of the evacuation space, when a non-insulating fire door is installed, the temperature inside the compartment exceeds the safety standard (US NFPA code) of 60°C 10 minutes after a fire occurs. The excess was confirmed, and the temperature was shown to soar to 100℃ after 25 minutes and to a whopping 170℃ after 1 hour. Accordingly, the Ministry of Land, Infrastructure and Transport recently announced the “Rules on Standards for Building Evacuation, Fire Protection Structure, etc.” which strengthened the performance standards for fire doors installed in apartment evacuation spaces. Accordingly, from April 5, 2016, heat blocking performance requirements for apartment evacuation spaces were introduced. As it is mandatory to install fire doors that last longer than 30 minutes, demand is expected to increase significantly.
종래의 철제 방화문의 경우 화염자체를 차단하는 능력은 우수한 것으로 알려져 있으나, 금속소재의 특성상 열전도도가 높아 차열능력 및 결로 방지능력에 취약한 문제가 있었다. 또한 방화문의 경우 아파트 내부 실내에 위치하여 목재문 대비 인테리어 통일성을 해치게 되어 차열 목재 방화문의 필요성이 대두되고 있다. Conventional steel fire doors are known to be excellent in blocking flames, but due to the nature of the metal material, they have high thermal conductivity, which makes them vulnerable to heat insulation and condensation prevention. In addition, in the case of fire doors, they are located indoors inside apartments, which undermines the interior unity compared to wooden doors, so the need for heat-insulating wooden fire doors is emerging.
종래 목재방화문의 경우 유리섬유, 그라스울 및 미네랄울 등의 침상형태의 섬유 충전재를 사용하여 목재 방화문을 구성하는 것이 보통이었다. 종래 목재 방화문의 골재는 원목에 난연재를 함침하거나 일반 단판적측판(LVB; laminated veneer board)을 사용하여 목재문의 프레임을 구성하였다. 원목의 경우 목재 특성상 시간이 지날수록 변형가능성이 높아지고, 일반 LVB의 경우 난연 성능을 확보하지 못하는 단점이 있었다. 상기 목재 방화문에 적용되는 접착제에 있어서도 종래의 유기 접착제 성분은 화재시 유독가스를 방출하고, 고열에서의 접착성을 유지하지 못하는 단점이 있었다. In the case of conventional wooden fire doors, it was common to construct wooden fire doors using needle-shaped fiber fillers such as glass fiber, glass wool, and mineral wool. In the past, the aggregate of wooden fire doors was made by impregnating flame retardant materials into solid wood or using general laminated veneer board (LVB) to construct the frame of the wooden door. In the case of raw wood, the possibility of deformation increases over time due to the nature of the wood, and in the case of general LVB, there was a disadvantage of not being able to secure flame retardant performance. Even in the adhesive applied to the wooden fire door, conventional organic adhesive components had the disadvantage of emitting toxic gases in case of fire and not maintaining adhesiveness at high temperatures.
종래의 충전재의 재료로 사용되는 침상형태의 유리섬유는 특성상 화재시 분진이 발생하며, 이러한 분진이 인체 내부로 흡입하게 되면 폐의 내부에 유입되어 박히게 된다. 침상유리섬유가 폐의 내부에 박히게 되면 체외로 배출이 어려워 폐의 건강에 치명적인 악영향을 끼칠 수 있다. 또한, 생산자가 상기 자재들을 취급 시 피부에 접촉하게 되면 침상형태의 유리섬유가 피부조직에 상해를 입히게 되어 장시간 고통에 노출되는 문제점이 우려된다. Due to the nature of needle-shaped glass fibers used as materials for conventional fillers, they generate dust in the event of a fire, and when such dust is inhaled into the human body, it flows into the inside of the lungs and becomes lodged. If needle-shaped glass fibers become lodged inside the lungs, they are difficult to expel out of the body and can have a fatal adverse effect on the health of the lungs. In addition, there is concern that if a producer comes into contact with the skin when handling the above materials, the needle-shaped glass fibers may damage the skin tissue and expose the user to long-term pain.
종래의 기술로서 KR1281366 ‘목재 방화도어’는 실내도어의 소재를 목재 및 방화유리를 적용하여 화재 발생 시 방화유리의 깨짐과 이탈을 방지하고 내화성능이 우수하고 실내 인테리어와 접목이 가능한 목재방화문을 개시한 바 있다. 상기 기술의 기능 및 외관은 우수하나 차열유리는 고가이며 수급의 한계가 있기 때문에 상용화의 한계가 있었다.As a conventional technology, KR1281366 'wooden fire door' uses wood and fire glass as interior door materials to prevent the fire glass from breaking and coming off in the event of a fire, and is a wood fire door that has excellent fire resistance and can be integrated into the interior. It has been done. Although the function and appearance of the above technology are excellent, heat-insulating glass is expensive and has limited supply and demand, so there are limits to commercialization.
KR1531357 ‘탄화보드를 사용한 목재방화문’은 탄화보드를 사용한 목재방화문으로 십자형태의 목재로 틀이 제작되어 있으며 틀 사이 형성된 공간에 불연재가 충전되어 구성된 형태로 탄화보드와 불연보드를 사용하여 화재안전성을 지닌 방화문을 개시한 바 있다. 상기의 기술에 따르면 방화성능 및 강성을 확보하기 위해서는 보드의 두께가 굵어지고 이로 인해 경량의 실내도어로는 상용화의 한계점이 있었다.KR1531357 'Wooden fire door using carbonized board' is a wooden fire door using carbonized board. The frame is made of cross-shaped wood, and the space formed between the frames is filled with incombustible material to ensure fire safety by using carbonized board and non-combustible board. Jinjin fire doors have been launched. According to the above technology, in order to secure fire prevention performance and rigidity, the thickness of the board had to be thick, which led to limitations in commercialization as a lightweight indoor door.
US9243444 B2 ‘방화문(Fire rated door)’은 내화성 복합 방화소재를 사용한 방화문의 구성으로 60~90중량%의 석고, 1.5~26 중량%의 섬유 및 0.5~6중량%의 레올로지 개질제를 포함하는 복합재료로 구성되어 있는 기술을 개시한 바 있다. 상기의 기술은 완전 자동화된 제조공정에 적합하지만 두꺼운 보드의 사용으로 인해 실내도어로써의 무게가 적합하지 아니한 문제점이 있었다.US9243444 B2 'Fire rated door' is a fire door made of fire-resistant composite fire-resistant material, and is a composite material containing 60-90% by weight of gypsum, 1.5-26% by weight of fiber, and 0.5-6% by weight of rheology modifier. A technology consisting of materials has been disclosed. Although the above technology is suitable for a fully automated manufacturing process, there is a problem in that the weight is not suitable for an indoor door due to the use of thick boards.
본 발명의 목표는 화재 발생시 대피하는 피난처 격실의 출입구를 화재 및 유독가스로부터 인명을 보호해주는 목재 차열 방화문을 제공하는데 있다. 종래의 목재방화문의 경우 기밀한 충전이 불가하여 차열 성능이 떨어지는 문제점이 발생되어왔다. 본 발명은 이러한 문제점을 개선하고, 종래의 방화문 대비 방화, 차열, 차염, 차연, 단열이 뛰어난 골재, 판재, 접착제, 내부 충전재를 개선하여 가격 대비 기술경쟁력을 지닌 목재 방화문 기술을 제공하고자 한다. The goal of the present invention is to provide a wooden insulating fire door that protects people from fire and toxic gases at the entrance to a refuge compartment where people escape in the event of a fire. In the case of conventional wooden fire doors, there has been a problem of poor heat insulation performance due to the inability to fill airtightly. The present invention aims to improve these problems and provide wood fire door technology with price-competitive technology by improving aggregates, plates, adhesives, and internal fillers that are superior in fire prevention, heat insulation, flame retardancy, and insulation compared to conventional fire doors.
본 발명은 프레임, 충전재, 외부패널, 접착제를 직접 설계하여 종래의 제품대비 강화된 화염차단성능, 차열성능, 내구성능, 단열성능, 차연성능, 결로 저감 성능을 확보하기 위해 각 소재의 조성비율을 조절 하여 다양한 샘플을 제작하고, 성능평가를 거쳐 반영된 데이터를 통해 각 구성요소의 제작 기술을 보강하여 법적 기준치 보다 우수한 내화성능, 물리적 성능, 단열, 차연성능을 향상시켜 고기능성이며 제조단가를 절감한 제품을 제공하고자 한다. The present invention directly designs the frame, filler, external panel, and adhesive, and adjusts the composition ratio of each material to secure enhanced flame-blocking performance, heat-shielding performance, durability performance, insulation performance, smoke-blocking performance, and condensation reduction performance compared to conventional products. By adjusting and producing various samples, and reinforcing the manufacturing technology of each component through the data reflected through performance evaluation, the fire resistance performance, physical performance, insulation, and smoke-blocking performance are improved to be better than legal standards, making it highly functional and reducing manufacturing costs. We want to provide products.

As shown in Figures 1 and 2, the present invention provides a fire door, including a fire resistant plate 100 having heat dissipation and fire prevention performance; A fire-resistant frame 200 installed on the edge of the fire-resistant plate 100;
상기 내화판재(100)의 앞뒤면을 커버하는 외부판재(300);An external plate (300) covering the front and back surfaces of the fireproof plate (100);
를 포함하여 구성되며,It consists of:
상기 내화판재(100)는 무기섬유로 제조되는 제1무기섬유층(110)과;The fireproof plate 100 includes a first inorganic fiber layer 110 made of inorganic fiber;
내부충전재층(120) 및 제2무기섬유층(130);Internal filler layer 120 and second inorganic fiber layer 130;
이 적층되어 구성되는 것을 특징으로 하는 방화문을 제공한다. Provides a fire door characterized in that it is constructed by lamination.
상기 외부판재(300)는 내화마감제가 적용되며, 외관 디자인을 형성하고 화염에 직접 면하여 화염을 차단하는 역할을 하며, 상기 내부충전재층은 방화시 화염과 열을 차단하고 단열 및 결로방지의 기능을 수행하게 된다. 또한, 상기 내화프레임(200)은 고온상황에서 방화문의 형상을 유지시켜주는 기능을 갖는다. 상기의 각 구성요소들은 무기접착제에 의해 접착될 수 있으며, 상기 무기접착제는 무기파우더, 난연재, 비할로겐 수용성수지, 경화제로 구성된 이액형 난연 접착제가 적용될 수 있다. The external plate 300 is applied with a fire-resistant finish, forms an exterior design and serves to block flames by directly facing the flame, and the internal filler layer blocks flame and heat during fire prevention and functions as insulation and condensation prevention. will be performed. Additionally, the fire resistant frame 200 has the function of maintaining the shape of the fire door in high temperature situations. Each of the above components may be bonded using an inorganic adhesive, and the inorganic adhesive may be a two-component flame retardant adhesive consisting of inorganic powder, flame retardant, non-halogen water-soluble resin, and hardener.
종래의 유기접착제는 화재시 유독가스를 방출하고, 고열에서의 접착성을 유지하지 못하는 단점이 존재하였다.Conventional organic adhesives had the disadvantage of emitting toxic gases in case of fire and not maintaining adhesiveness at high temperatures.
이러한 종래의 접착재의 경우 본 출원인의 모의방화 테스트시 고온상에 장시간 노출이 되면 접착력을 잃게 되어 화기가 벌어진 틈새로 확산되어 차염 및 차연성능이 급격하게 저하되는 현상이 발생하였다.In the case of such conventional adhesives, when exposed to high temperatures for a long period of time during the applicant's simulated firefighting test, adhesive strength was lost and fire spread into open gaps, causing a rapid decrease in flame blocking and blocking performance.
이에, 본 발명은 목재방화문을 위한 기존의 우레탄 발포수지 접착제를 대신하여 무기질파우더, 난연재, 수용성수지에 아민계 경화제를 혼합하여 5,000~7,000정도의 저점도 이액형 접착제를 제공한다. 상기 저점도 이액형 접착제는 높은 젖음성을 확보하여 제조공정의 편의성을 확대하고, 화재발생시 고온상에서 접착력을 유지하는 효과를 제공한다. 상기 무기질접착제는 수산화 알류미늄, 산화구리, 산화아연, 규산소다, 메틸셀룰로오스의 무기질파우더, 멜라민계 난연제, 비할로겐 수용성 수지, 아민계 경화제 중 선택되는 하나 이상을 포함하는 이액형 접착제인 것이 바람직하다. 상기와 같은 구성에 따라 본 발명에서의 접착제는 5,000~7,000 정도의 저점도를 형성하여 젖음성(fully wetted)을 향상 시켜 제작의 편의성을 높이고, 후 공정으로 80~100℃ 에서의 핫프레스(Hot Press) 공정을 통해 고온상태에서 접착함으로 난연 효과가 장시간 지속되는 고기능성 접착제를 제공한다. 또한, 본 발명은 이에 나아가, 접착제 고형분의 전체 함량대비 6~7%(몰비)의 규산칼륨 및 리튬실리케이트를 추가한 결과 46h 열탕내수성, 내염수성(5% NaCl), 내산성(5% H2SO4), 내알카리성(5% NaOH) 특성이 향상됨을 확인할 수 있었다. Accordingly, the present invention provides a two-part adhesive with a low viscosity of about 5,000 to 7,000 by mixing an amine-based curing agent with inorganic powder, flame retardant, and water-soluble resin instead of the existing urethane foam adhesive for wooden fire doors. The low-viscosity two-component adhesive secures high wettability, expands the convenience of the manufacturing process, and provides the effect of maintaining adhesive strength at high temperatures in the event of a fire. The inorganic adhesive is preferably a two-component adhesive containing at least one selected from the group consisting of aluminum hydroxide, copper oxide, zinc oxide, sodium silicate, mineral powder of methyl cellulose, melamine-based flame retardant, non-halogen water-soluble resin, and amine-based curing agent. According to the above configuration, the adhesive in the present invention has a low viscosity of about 5,000 to 7,000 to improve the wettability (fully wetted), thereby increasing the convenience of manufacturing, and as a post-process, hot press at 80 to 100 ° C. ) process provides a high-performance adhesive with a long-lasting flame retardant effect by bonding at high temperatures. In addition, the present invention goes further, and as a result of adding 6 to 7% (molar ratio) of potassium silicate and lithium silicate compared to the total content of the adhesive solids, boiling water resistance for 46 hours, salt water resistance (5% NaCl), acid resistance (5% H2SO4), It was confirmed that the alkali resistance (5% NaOH) properties were improved.
상기 내화판재(100)는 무기섬유로 제조되는 제1무기섬유층(110)과, 내부충전재층(120) 및 제2무기섬유층(130)이 적층되어 구성되며, 상기 제1무기섬유층(110)과 제2무기섬유층(130)은 세라크울(Cerakwool; 세라믹단열재), 유리섬유 및 암면 중 선택된 하나 이상의 재질로 구성된다. 상기 제1무기섬유층(110)과 제2무기섬유층(130)은 난연재와 페놀수지와 같은 열경화성 수지를 함침시킨 후 프레스로 가열가압하여 경화시킬 수 있다. 상기 난연제는 암모니움포스페이트(Amonium Phosphate), 구아니딘(guanidine compound), 벤즈이소치아졸리논(Benzisothiazolinone) 및 에틸렌글리콜(ethylene glycol) 중 선택되는 하나 이상의 물질을 포함하여 구성될 수 있다. 이러한 구성은 표면을 개질시켜 차후 외부판재(300)의 접합이 긴밀하게 이루어질 수 있게 한다. The fireproof plate 100 is composed of a first inorganic fiber layer 110 made of inorganic fiber, an internal filler layer 120, and a second inorganic fiber layer 130, which are stacked, and the first inorganic fiber layer 110 and The second inorganic fiber layer 130 is made of one or more materials selected from Cerakwool (ceramic insulating material), glass fiber, and rock wool. The first inorganic fiber layer 110 and the second inorganic fiber layer 130 can be hardened by impregnating them with a flame retardant and a thermosetting resin such as a phenol resin and then heating and pressing them with a press. The flame retardant may include one or more substances selected from ammonium phosphate, guanidine compound, benzisothiazolinone, and ethylene glycol. This configuration modifies the surface so that the outer plate 300 can be closely bonded in the future.
상기 내부충전재층(120)은 무기섬유 25~35w%, 셀룰로오스섬유 25~35w%에 무기바인더졸 30~50w%이 함침되어 구성된다.The internal filler layer 120 is composed of 25 to 35 w% of inorganic fiber, 25 to 35 w% of cellulose fiber, and 30 to 50 w% of inorganic binder sol.
상기 무기섬유 25~35w%, 셀룰로오스섬유 25~35w%의 구성은 제조후 경화시 일정한 탄성을 지니면서도 내화성을 확보할 수 있는 최적의 구성비이다.The composition of 25 to 35 w% of inorganic fiber and 25 to 35 w% of cellulose fiber is the optimal composition ratio to ensure fire resistance while maintaining a certain elasticity when cured after manufacturing.
또한, 상기 내부충전재층(120)의 무기바인더졸은 실리카졸, 탄산칼슘, 수산화알루미늄(Al(OH)3), 산화마그네슘(MgO), 산화알루미늄(Al2O3), 알루미늄 분말, 아연 분말, 규산나트륨 혼합물에 황산, 질산, 인산, 붕산 및 아세트산 중 선택되는 하나 이상의 산을 첨가한 것이며, 상기 산은 상기 규산나트륨의 총 질량의 3-5w%로 첨가된다. 이때, 상기 실리카졸과 규산나트륨은 1:1의 비율로 혼합하는 것이 바람직하다. In addition, the inorganic binder sol of the internal filler layer 120 is silica sol, calcium carbonate, aluminum hydroxide (Al(OH)3), magnesium oxide (MgO), aluminum oxide (Al2O3), aluminum powder, zinc powder, and sodium silicate. One or more acids selected from sulfuric acid, nitric acid, phosphoric acid, boric acid, and acetic acid are added to the mixture, and the acid is added in an amount of 3-5w% of the total mass of the sodium silicate. At this time, it is preferable to mix the silica sol and sodium silicate in a 1:1 ratio.
상기 무기상기 바인더졸은 입도가 작은 실리카의 콜로이드 상태로 점도가 낮아 다공성 물질에 과도하게 함침될 수 있다. 이는 다공성 물질의 경량성, 단열성능 및 차열성능을 감소시키는 원인이 될 수 있다. 이에, 상기 상기 알루미늄 분말, 아연 분말은 이산화규소를 응집시켜 크기가 큰 콜로이드 입자를 형성하게 한다. 이에 따라 과도한 함침을 예방하고 점성이 높은 바인더를 형성할 수 있다. The inorganic binder sol is in a colloidal state of silica with a small particle size and has a low viscosity, so it may be excessively impregnated into porous materials. This may cause a decrease in the light weight, insulation performance, and thermal insulation performance of the porous material. Accordingly, the aluminum powder and zinc powder agglomerate silicon dioxide to form large-sized colloidal particles. Accordingly, excessive impregnation can be prevented and a highly viscous binder can be formed.
수분에 취약한 규산나트륨(Na2SO3)이 첨가됨에 따라 내수성을 확보할 필요성이 대두된다. 이에, 본 발명은 황산, 질산, 인산, 붕산 및 아세트산 중 선택되는 하나 이상의 산을 첨가한다. 상기의 산은 규산나트륨과 반응하여 불용성 나트륨염을 생성한다. 황산을 첨가한 경우 불용성 염인 황산나트륨이 형성되며 반응식은 하기의 식1과 같다. As sodium silicate (Na2SO3), which is vulnerable to moisture, is added, the need to secure water resistance emerges. Accordingly, the present invention adds one or more acids selected from sulfuric acid, nitric acid, phosphoric acid, boric acid, and acetic acid. The above acid reacts with sodium silicate to produce an insoluble sodium salt. When sulfuric acid is added, sodium sulfate, an insoluble salt, is formed, and the reaction equation is as shown in Equation 1 below.
식1) Na2O + H2SO4 -> Na2SO4 + H2OEquation 1) Na2O + H2SO4 -> Na2SO4 + H2O
이와같이 생성된 불용성 염은 실리카졸이 응집될때 불투성 막을 형성하여 수분을 차단하게되며 내수성을을 확보할 수 있게 한다. The insoluble salt produced in this way forms an impermeable film when the silica sol aggregates, blocking moisture and ensuring water resistance.
또한, 본 발명은 상기 무기바인더졸에 플라이에시(fly ash), 질석 및 펄라이트가 첨가되는 구성을 제공한다. 상기 플라이에시(fly ash), 질석 및 펄라이트는 다공성 및 발포성 무기질로서 전체부피당 질량을 감소시켜 경량화를 구현할 수 있으며, 내화성능을 향상시키는 효과를 기대할 수 있다. 그러나, 상기 펄라이트는 상대적으로 고가의 재료이기 때문에 제조단가를 높이게 된다. 이에, 상기 무기바인더졸에 칼슘 0.5~1.5w%을 첨가하여 전체적인 강도를 향상시켜 경량화 및 내화성능을 향상시킴으로써 펄라이트의 투입량을 낮출 수 있다. Additionally, the present invention provides a configuration in which fly ash, vermiculite, and perlite are added to the inorganic binder sol. The fly ash, vermiculite, and perlite are porous and foamable minerals that can achieve weight reduction by reducing the mass per volume and can be expected to improve fire resistance performance. However, since the perlite is a relatively expensive material, the manufacturing cost increases. Accordingly, by adding 0.5 to 1.5 w% of calcium to the inorganic binder sol, the overall strength is improved, thereby reducing weight and improving fire resistance, thereby lowering the amount of pearlite input.
도3은 본 발명의 방화문의 내부 충전재층에 발포코팅층을 적용한 실시예의 요부단면도이다. 상기 발포코팅층(140)은 방화문의 가열시 발생되는 내화판재(100)와 내화프레임(200)간의 유격을 메워줄 수 있다. 상기 발포코팅층(140)은 내화도료로서, 팽창성 흑연(expandable graphite) 및 수산화알루미늄을 포함하여 구성되며, 추가적으로 폴리비닐알콜, 폴리에틸렌글리콜, 메틸셀룰로오스 및 팽윤성 점토 중에서 선택된 1종 이상의 물질을 포함하는 것이 바람직하다. 상기 발포성 내화도료는 화재 발생시 내부 충전을 기밀하게 하는 팽창능력을 조절하여 방화문의 내구성 한도 내에서 내부를 가장 치밀하게 팽창하는 혼합비를 가진다. Figure 3 is a cross-sectional view of the main part of an embodiment in which a foam coating layer is applied to the internal filler layer of the fire door of the present invention. The foam coating layer 140 can fill the gap between the fireproof plate 100 and the fireproof frame 200 that occurs when the fire door is heated. The foam coating layer 140 is a fire-resistant paint and is composed of expandable graphite and aluminum hydroxide, and additionally preferably contains at least one material selected from polyvinyl alcohol, polyethylene glycol, methyl cellulose, and swellable clay. do. The foamable fire-resistant paint has a mixing ratio that expands the interior most densely within the durability limit of the fire door by adjusting the expansion ability to seal the internal filling in the event of a fire.
도4는 내화프레임의 제조를 설명한 설명도이다. 상기 내화프레임(200)은 상기 내화판재(100)를 막대형상으로 절단한 후, 단면의 방향이 상기 내화판재(100)의 단면의 방향에 대하여 90도를 향하도록 회전시켜 접합시켜 형성시키게 된다. 상기의 구성에 따라 가열시 뒤틀리는 응력을 분산시킬 수 있으며, 제조시간을 단축시킬 수 있는 효과를 기대할 수 있다. Figure 4 is an explanatory diagram explaining the manufacturing of a fire-resistant frame. The fireproof frame 200 is formed by cutting the fireproof plate 100 into a bar shape, rotating it so that the direction of the cross section faces 90 degrees with respect to the direction of the cross section of the fireproof plate 100, and joining them. According to the above configuration, the stress that distorts during heating can be distributed, and the effect of shortening the manufacturing time can be expected.
도5는 본 발명의 방화문 어셈블리의 단면도이고, 도6은 본 발명의 방화문 어셈블리의 요부단면도이다. 본 발명은 방화문과 상기 방화문에 대응되는 문틀을 포함하는 방화문 어셈블리에 있어서, 상기 방화문(1)은 상술한 바와 같은 방화문이며, 상기 문틀(2)은 방화문(1)과 문틀(2)의 접면에 판형의 팽창흑연실(Expandable graphite seal)(21)이 설치되는 것을 특징으로 한다. Figure 5 is a cross-sectional view of the fire door assembly of the present invention, and Figure 6 is a cross-sectional view of the main part of the fire door assembly of the present invention. The present invention relates to a fire door assembly including a fire door and a door frame corresponding to the fire door, wherein the fire door (1) is a fire door as described above, and the door frame (2) is provided at an interface between the fire door (1) and the door frame (2). It is characterized in that a plate-shaped expandable graphite seal (21) is installed.
도7은 본 발명의 방화문 어셈블리의 팽창흑연실(21)이 가열로 인해 발포된 상태를 도시한 예시도이다. 방화문(1)은 고온고압의 환경에서 형태의 변형이 일어날 수 있다. 이에 방화문(1)과 문틀(2)사이에 유격이 발생할 수 있으며, 이러한 유격은 방열, 단열, 차연성을을 크게 저하시키게 된다. 상기의 팽창흑연실(21)은 도7에서 도시된 바와 같이, 이러한 유격을 메워주는 기능을 수행한다. Figure 7 is an exemplary diagram showing a state in which the expanded graphite chamber 21 of the fire door assembly of the present invention is foamed due to heating. The fire door 1 may be deformed in a high-temperature and high-pressure environment. As a result, a gap may occur between the fire door (1) and the door frame (2), and this gap significantly reduces heat dissipation, insulation, and smoke-blocking properties. As shown in FIG. 7, the expanded graphite chamber 21 functions to fill this gap.
한편, 상기 팽창흑연실(21)의 팽창수준을 조절할 필요가 있다. 팽창흑연실(21)의 팽창이 과도하게되면 내화판재(100)를 밀어내어 방화문이 파손될 우려가 있으며, 팽창수준이 작게 되면 유격을 충분히 메우지 못하는 문제가 발생할 수 있다. Meanwhile, it is necessary to control the expansion level of the expanded graphite chamber 21. If the expansion of the expanded graphite chamber 21 is excessive, there is a risk that the fireproof door may be damaged by pushing out the fireproof plate 100, and if the level of expansion is low, a problem may occur in which the gap cannot be sufficiently filled.
또한, 상기 문틀(2)은 상기 방화문(1)이 일방향으로 개폐되도록 개폐방향 반대측에 턱구조의 스토퍼(22)가 설치되며, 상기 스토퍼(22)와 상기 방화문(1)의 접면에 기밀성 확보를 위한 가스켓(23)이 설치되는 것이 바람직하다. 상술한 바와 같이, 문틀(2)과 방화문(1)간의 긴밀성은 방열, 단열, 차연성에 중요한 요인이다. 상기의 가스켓(23)은 문틀(2)과 방화문(1)간의 긴밀성을 확보하는 효과를 기대할 수 있다. In addition, the door frame (2) is provided with a stopper (22) of a jaw structure on the opposite side of the opening/closing direction so that the fire door (1) can be opened and closed in one direction, and airtightness is secured at the contact surface between the stopper (22) and the fire door (1). It is desirable for a gasket 23 to be installed. As described above, the closeness between the door frame 2 and the fire door 1 is an important factor in heat dissipation, insulation, and insulation. The above gasket 23 can be expected to have the effect of ensuring tightness between the door frame 2 and the fire door 1.
도8은 본 발명의 방화문 어셈블리의 두 개의 가스켓을 적용한 실시예의 요부단면도이다. 도8의 실시예에서, 상기 문틀(2)은 상기 방화문(1)이 일방향으로 개폐되도록 개폐방향 반대측에 턱구조의 스토퍼(22) 및 추가적인 내화판체(25)가 설치되며, 상기 스토퍼(22)와 상기 방화문(1)의 접면에 기밀성 확보를 위한 가스켓(23)이 설치되고, 추가적인 내화판체(25)와 방화문(1) 사이에 추가적인 가스켓(24)이 설치된다. 이러한 가스켓의 이중구조는 문틀(2)과 방화문(1)간의 긴밀성을 보다 공고히 할 수 있다. Figure 8 is a cross-sectional view of the main part of an embodiment of the fire door assembly of the present invention using two gaskets. In the embodiment of Figure 8, the door frame 2 is provided with a stopper 22 and an additional fireproof plate 25 on the opposite side of the opening and closing direction so that the fire door 1 can be opened and closed in one direction, and the stopper 22 ) A gasket 23 is installed at the contact surface of the fire door 1 to ensure airtightness, and an additional gasket 24 is installed between the additional fire resistant plate 25 and the fire door 1. This dual structure of the gasket can further strengthen the closeness between the door frame (2) and the fire door (1).
