Description

경량골재를 이용한 내화성 판재조성물{Incombustible panel composite used lightweight aggregate}Fireproof panel composite using lightweight aggregate {Incombustible panel composite used lightweight aggregate}

본 발명은 경량골재를 이용한 내화성 판재조성물에 관한 것으로서, 더욱 상세하게는 건축물의 내외부 방화 및 내화벽체로 사용할 수 있는 내화성 판재조성물에 관한 것이다.The present invention relates to a fire resistant plate composition using lightweight aggregate, and more particularly, to a fire resistant plate composition which can be used as an internal and external fire protection and fireproof wall of a building.

최근 들어, 건축물의 벽체를 시공함에 있어서 습식공법에서 건식공법으로의 전환이 눈에 띄게 늘어가고 있는데, 이는 건식공법이 습식공법에 비하여 공기의 단축, 시공의 용이함, 품질관리 등의 이점을 갖기 때문이다. 또한, 경량구조의 적용에 따른 건축물의 구조적인 경량성과 가변형 벽체로서의 적용이 용이함에 따라, 건식벽체로서 적용가능한 제품에 대한 요구가 증대되고 있다.Recently, the transition from wet method to dry method has been increased in the construction of the wall of the building, because the dry method has advantages such as shortening of air, ease of construction and quality control compared to the wet method. to be. In addition, as the structural light weight of the building according to the application of the light weight structure and easy to apply as a variable wall, there is an increasing demand for a product that can be applied as a dry wall.

일반적으로 건축물의 건식벽체로서는 석고보드 또는 석면 시멘트판을 이용한 벽체나 콘크리트판넬 또는 스치로폼 콘크리트 합성판넬 등이 있다. 이중 석고보드는 가장 일반적으로 사용되고 있으나, 내화성능이 떨어지며 충격에 약한 단점을 안고 있다. 내화성능을 보강한 방화석고보드가 적용되고 있기도 한데, 이는 석고보드의 내화성능을 보강하기 위하여 무기광물성 섬유를 첨가하여 제조된 것이나 이 또한 내화성능을 충분히 발휘하지 못하므로 겹쳐 사용하거나 무기광물성 단열재와 함께 사용하여 칸막이벽으로 사용되고 있다. In general, as a dry wall of a building, there are walls, concrete panels, or styrofoam concrete composite panels using gypsum board or asbestos cement board. Double gypsum board is the most commonly used, but the fire resistance is poor and has a weak disadvantage in impact. Fire-resistant gypsum board with reinforced fire resistance has been applied, but it is manufactured by adding inorganic mineral fiber to reinforce the fire resistance of gypsum board, but it also cannot be used because it does not fully exhibit fire resistance. Used together as a partition wall.

석면 시멘트판의 경우, 주원료인 석면이 발암물질로 규정되어 그 사용이 제한적으로, 최근에는 거의 사용이 되지 않고 있으며, 무석면 시멘트판의 경우에도 비중이 높고 습기에 취약하여 일부 제한된 용도에만 적용되고 있다. In the case of asbestos cement board, asbestos, which is the main raw material, is defined as a carcinogen, its use is limited, and it is rarely used recently. In the case of asbestos cement board, it is applied only to some limited uses because of its high specific gravity and susceptibility to moisture. .

또한, 판재로서 콘크리트 판넬이나 스치로폼 콘크리트 합성판넬이 있는데, 콘크리트판넬은 시멘트와 규석분을 주로 사용하여 성형한 제품으로 내화성능은 우수하나, 비중이 크고 마감면이 수려하지 못하여 건축물의 내부 칸막이 벽체로는 사용되지 못하고 있다. In addition, there are concrete panels or styrofoam concrete composite panels, which are molded products using mainly cement and silica powder, which have excellent fire resistance, but have a high specific gravity and are not attractive for finishing walls. Is not used.

이를 보완하기 위하여 경량골재 및 시멘트를 이용하여 제조한 경량 콘크리트 판넬도 있으나 이 또한 마감면이 수려하지 못하고 충분한 내화성능을 발휘하기 위해서는 두꺼워져 사용이 제한되고 있다. In order to compensate for this, there is also a lightweight concrete panel manufactured using lightweight aggregate and cement, but this also has a limited finishing surface and is thickened to exhibit sufficient fire resistance.

이에 본 발명은 이러한 단점들을 해결하기 위한 것으로, 경량골재 및 무기충전재를 주로 사용하여 가볍고 제조 및 시공이 용이하면서도, 화재시 탄화성 소재의 차콜형성화를 통하여 충분한 내화성능을 발휘하면서 습기에 강한 내화성 판재조성물을 제공하는데 그 목적이 있다. Accordingly, the present invention is to solve these shortcomings, using light aggregates and inorganic fillers, mainly light and easy to manufacture and construction, while exhibiting sufficient fire resistance through charcoal formation of the carbonizable material in the event of fire, strong fire resistance The purpose is to provide a sheet composition.

또한 본 발명은 화재시 화재온도의 상승에 따른 온도별 화재저항메카니즘을 형성할 수 있도록 구성되어, 내화성능이 크게 향상된 내화성 판재조성물을 제공하는데 그 목적이 있다. In addition, the present invention is configured to form a fire resistance mechanism for each temperature according to the rise of the fire temperature in the event of fire, the object of the present invention is to provide a fire-resistant plate composition with greatly improved fire performance.

상기와 같은 목적을 달성하기 위한 본 발명의 내화성 판재조성물은 다공성의 경량골재 5-40중량%, 무기충전재 5-40중량%, 탄화성 섬유 3-25중량% 및 상온에서 액상인 차콜형성제 5-25중량%(고형분 함량기준)를 포함하는 것을 그 특징으로 한다.Fire-resistant plate composition of the present invention for achieving the above object is 5-40% by weight of porous lightweight aggregate, 5-40% by weight of inorganic filler, 3-25% by weight of carbonizable fiber and the charcoal forming agent 5 at room temperature It is characterized by including -25% by weight (based on solids content).

이에 더하여 경화제, 난연제, 백화방지제 및 계면활성제를 단독 또는 혼합하여 포함할 수도 있다. In addition, a curing agent, a flame retardant, an anti-whitening agent and a surfactant may be included alone or in combination.

이와같은 본 발명을 더욱 상세하게 설명하면 다음과 같다.The present invention will be described in more detail as follows.

본 발명 내화성 판재조성물의 주재료인 다공성의 경량골재는 내부에 다수의 기공을 함유하여 가볍고 열전달저항이 뛰어나, 내화, 단열, 흡음 등의 용도로 많이 사용되는 소재로서, 일예로 팽창퍼라이트, 팽창질석, 팽창경석, 광물질에 기포를 함유케한 중공구체 및 광물 생성시 기포가 존재하는 화산재나 부석, 발포폴리스티렌입자 중에서 1종 이상을 선택하여 단독 또는 혼합하여 사용할 수 있다. 이들 경량골재는 전체 조성물을 기준으로 5-40중량%로 포함되는 바, 그 함량이 5중량% 미만이면 밀도가 높아져 건식벽체로서의 이점이 상실되며, 30 중량%를 초과하여 사용할 경우에는 재료분리가 발생하여 조성물의 균일한 성능을 발휘하기 힘들며, 판재 조성물의 강도가 낮아지고 표면이 매끄럽지 못하게 된다.Porous lightweight aggregate, which is the main material of the fire-resistant plate composition of the present invention, contains a large number of pores therein, and is light and excellent in heat transfer resistance, and is widely used for applications such as fire resistance, heat insulation, and sound absorption, for example, expanded perlite, expanded vermiculite, It can be used alone or in combination with one or more selected from expanded pumice, hollow spheres containing bubbles in minerals, and volcanic ash, pumice, and expanded polystyrene particles in which bubbles exist during mineral generation. These lightweight aggregates are contained in 5-40% by weight based on the total composition, the content of which is less than 5% by weight is high density loses the advantage as a drywall, when used in excess of 30% by weight of material separation It is difficult to produce uniform performance of the composition, the strength of the plate composition is lowered and the surface is not smooth.

무기충전재는 판재 조성물의 제조시 재료의 혼합을 밀실하게 하여 강도를 증진시키고, 표면을 매끄럽게 하며, 전반적으로 제조원가를 낮춤으로써 경제적인 판재조성물을 제조할 수 있도록 한다. 이같은 역할을 하는 무기충전재로는 철강제련에서 발생하는 부산물인 고로슬래그나 화력발전소 부산물인 플라이애쉬, 또는 석분, 탈크, 방해석, 돌로마이트, 중탄산칼슘 중에서 선택된 1종 이상을 혼합하여 사용할 수 있다. 이들 무기충전재는 전체 조성물을 기준으로 5-40중량% 되도록 포함되는 바, 무기충전재는 비중이 상대적으로 높은 제품으로서, 40중량%를 초과하여 사용할 경우에는 조성물의 밀도가 높아져 경량소재로서의 특징을 상실하게 된다. Inorganic fillers enable the production of economical sheet compositions by tightly mixing the materials in the manufacture of the plate compositions to enhance strength, smooth the surface, and lower the overall manufacturing cost. Inorganic fillers that play such a role can be used by mixing at least one selected from blast furnace slag, a by-product from steel smelting, fly ash, a byproduct of thermal power plants, or stone powder, talc, calcite, dolomite, and calcium bicarbonate. These inorganic fillers are included so that 5-40% by weight based on the total composition, the inorganic filler is a product with a relatively high specific gravity, when used in excess of 40% by weight the density of the composition becomes high lose the characteristics as a lightweight material Done.

탄화성 섬유는 판재조성물의 휨강도를 증진시키고, 화재시 판재조성물 중 일부가 수축으로 인하여 균열을 일으키는 것을 방지하기 위한 것으로, 전체 조성물을 기준으로 3-25중량%로 사용한다. The elastic fibers are used to increase the flexural strength of the plate composition and to prevent cracking of some of the plate composition due to shrinkage in case of fire, and is used at 3-25% by weight based on the total composition.

탄화성 섬유로는 폐신문지, 폐지폐, 폐종이박스 등을 파쇄한 종이섬유, 목분, 면사 및 폴리에스테르계, 폴리에틸렌계, 폴리프로필렌계 등의 가연성 화학섬유 중에서 선택된 1종 이상의 것을 들 수 있다. Examples of the carbonizable fibers include one or more selected from among combustible chemical fibers such as waste paper, waste paper, waste paper box, paper fiber, wood flour, cotton yarn and polyester, polyethylene, and polypropylene.

탄화성 섬유의 함량이 전체 조성물 중 30중량% 초과면 판재조성물의 내화성능을 약화시키고, 내습성을 저하시키는 문제가 있을 수 있다. If the content of the carbonizable fiber exceeds 30% by weight of the total composition, there may be a problem of weakening the fire resistance of the plate composition and lowering the moisture resistance.

즉, 상기한 탄화성 섬유는 가연성으로, 내화성 소재로서의 단점을 보유하고 있기 때문에 이를 근본적으로 개선하기 위하여 상온에서 액상인 차콜형성제를 전체 조성물에 대해서 고형분 기준으로 3-25중량% 되도록 포함한다. 차콜형성제는 탄화성 섬유의 장점을 그대로 보유하기 위하여 섬유의 형상을 유지시키면서도, 탄화성 섬유의 표면에 도포됨으로써 차콜화하여 화재에 우수한 성능을 발휘할 수 있도록 한다. That is, the above-mentioned carbonizable fiber is flammable and has a disadvantage as a refractory material, so that the charcoal former which is liquid at room temperature is 3-25% by weight based on solids with respect to the whole composition in order to fundamentally improve it. Charcoal formers are applied to the surface of the carbonizable fibers while maintaining the shape of the carbonized fibers in order to retain the advantages of the carbonizable fibers, charcoalized to exhibit excellent performance in fire.

차콜형성제는 무기질이면서 상온에서 액상으로 존재하여 전체 조성물에 고루 혼합이 용이하고, 탄화성 섬유와의 접착이 견고하여 착화를 지연시키고 탄화성 섬유로부터 산소를 차단시켜 단열성이 뛰어난 차콜을 형성하게 한다. Charcoal formers are inorganic and exist in liquid phase at room temperature, making it easy to mix evenly in the whole composition, and firmly adhering to the carbonizable fibers, delaying ignition and blocking oxygen from the carbonizable fibers to form charcoal with excellent thermal insulation. .

차콜형성제의 일예로는 규산나트륨, 규산칼륨, 인산, 인산염 접착제를 단독 또는 혼합하여 사용할 수 있다. As an example of the charcoal forming agent, sodium silicate, potassium silicate, phosphoric acid, phosphate adhesives may be used alone or in combination.

여기서, 규산나트륨, 규산칼륨의 경우에는 저가의 일반 난연제품을 생산하는데 적절하며, 인산, 인산염 접착제의 경우에는 고온에 안정한 특수 고부가성 난연제품을 생산하는데 효과가 있다. Here, in the case of sodium silicate and potassium silicate, it is suitable for producing low-cost general flame retardant products, and in the case of phosphoric acid and phosphate adhesives, it is effective to produce special high-addition flame retardant products that are stable at high temperatures.

차콜형성제의 조성비율이 전체 조성물 중 5중량% 미만인 경우에는 탄화성 섬유와의 접착이 미미하여 완전한 난연화가 이루어지지 않으며, 조성비율이 25중량%를 초과할 경우에는 내화성능은 향상되지만, 밀도가 높아져 경량성과 단열성, 흡음성능이 저하되는 문제가 발생하게 된다. When the composition ratio of the charcoal forming agent is less than 5% by weight of the total composition, the adhesion with the carbonizable fibers is insignificant, so that no complete flame retardation occurs. When the composition ratio exceeds 25% by weight, the fire resistance is improved, but the density is increased. As a result, there is a problem that the light weight, heat insulation, sound absorption performance is lowered.

상기한 바와 같이, 본 발명의 내화성 판재조성물은 가연성 소재인 탄화성 섬유에 대한 차콜화를 통하여 화재에 대한 안전성을 확보하였으나, 본래 가연성인 탄화성 섬유가 짧은 시간에 고온에 노출될 경우에는 착화로 화염이 발생할 수 있으므로 급격한 온도상승을 막아 화염을 방지할 수 있도록 난연제를 첨가하면 더욱 효과적인 내화성을 부여할 수 있다. 난연제의 일예로는 탄산칼슘, 탄산마그네슘, 탄산암모늄, 탄산나트륨, 수산화알루미늄, 수산화마그네슘, 붕사, 붕산, 석고, 소석회, 명반 등 화학조성 중에 결정수 및 불연소성 가스를 다량 함유하는 물질들을 들 수 있다.As described above, the fire-resistant plate composition of the present invention secured fire safety through charcoalization of the carbonizable fiber, which is a combustible material, but when the flammable carbonizable fiber is exposed to high temperature in a short time, the ignition furnace Flames may occur, so adding a flame retardant to prevent a sudden rise in temperature to prevent flames can give more effective fire resistance. Examples of flame retardants include materials containing large amounts of crystalline water and incombustible gases in chemical compositions such as calcium carbonate, magnesium carbonate, ammonium carbonate, sodium carbonate, aluminum hydroxide, magnesium hydroxide, borax, boric acid, gypsum, slaked lime and alum. .

다시말해, 차콜형성제로 처리된 탄화성 섬유의 착화온도는 400-800℃이나 서서히 분해가 진행되는 온도는 300-400℃로, 이때 발생하는 가연성 가스로 인하여 낮은 온도에서도 화염이 발생할 수 있다. 따라서 상기의 온도 이하에서 화염의 착화를 방지할 수 있는 불연소성 가스를 발생하는 성분, 즉 상기한 난연제를 혼합시키면 가연성 가스의 농도를 저하시켜 화염을 차단할 수 있다. 난연제는 보다 강화된 내화성능이 요구되는 부위에 사용되는 판재조성물에 첨가하는 것으로, 난연제의 첨가시 그 함량은 전체 조성물 중 15중량%를 초과하지 않는 범위인 것이 바람직하다. 난연제의 함량이 15중량%를 초과하게 되면 판재조성물이 무거워지고, 화재저항메카니즘이 불규칙적으로 발생하는 문제가 발생할 수 있기 때문이다.In other words, the ignition temperature of the charcoal fiber treated with the charcoal forming agent is 400-800 ° C., but the temperature at which the decomposition proceeds slowly is 300-400 ° C. The flame may be generated even at low temperatures due to the combustible gas generated at this time. Therefore, when the non-combustible gas generating components, that is, the above-described flame retardant, are mixed to prevent the flame from ignition below the above temperature, the concentration of the flammable gas can be reduced to block the flame. The flame retardant is added to the plate composition to be used in the site where the enhanced fire resistance is required, the content of the flame retardant is preferably in the range not to exceed 15% by weight of the total composition. If the content of the flame retardant exceeds 15% by weight, the plate composition becomes heavy, and the problem that the fire resistance mechanism irregularly occurs may occur.

상기한 난연제는 성형품 내의 탄화성 섬유가 화염에 노출되었을 때 열분해를 일으킴으로써 착화에 필요한 가연성 가스의 농도를 저하시키거나 결정수를 배출함으로써 주위온도를 낮추어 착화를 지연시키며, 특히 고온에서 분해되는 난연제의 경우는 고온에서 분해되어 불연소성 가스를 발생시킴으로써 불연소성 가스에 의해 착화에 필요한 농도를 저하시키는 원리를 통해 착화를 지연시키는 화학적 효과를 줄 수 있다. The flame retardant causes thermal decomposition when the carbonizable fibers in the molded product are exposed to a flame, thereby lowering the concentration of flammable gas required for ignition or lowering the ambient temperature by releasing crystal water, thereby delaying ignition. In the case of can be decomposed at high temperature to generate a non-combustible gas through the principle of reducing the concentration required for complexing by the non-combustible gas can give a chemical effect to delay the ignition.

이러한 원리로 조성된 판재의 경우 소정의 두께를 가지고 있어 화염에 노출된 면과 그 반대편 면의 온도차이가 크게 나므로, 판재 전체적으로 난연제를 활성화시키기 위해서는 저온영역에서 분해되는 물질과 고온 영역에서 분해되는 물질을 혼합하여 사용할 때 그 효과가 크게 된다. In the case of the plate formed on this principle, the temperature difference between the surface exposed to the flame and the opposite side of the plate is greatly increased. Therefore, in order to activate the flame retardant as a whole, the material decomposed in the low temperature region and the material decomposed in the high temperature region. When used in combination, the effect is great.

이같은 반응의 메카니즘은 다음과 같다;The mechanism of this reaction is as follows;

①100-200℃의 낮은 온도에서 분해되는 난연제의 경우① In case of flame retardant decomposed at low temperature of 100-200 ℃

2(NH4)2CO3 +3O2 (열에너지) → 2CO2(Gas) + 2N 2(Gas) +8H2O2 (NH 4 ) 2 CO 3 + 3O 2 (thermal energy) → 2CO 2 (Gas) + 2N 2 (Gas) + 8H 2 O

Na2CO3 (열에너지) → CO2(Gas) + Na2ONa 2 CO 3 (thermal energy) → CO 2 (Gas) + Na 2 O

②800℃ 정도에서 분해되는 난연제의 경우② In case of flame retardant decomposed at about 800 ℃

CaCO3 (열에너지) → CaO + CO2(Gas)CaCO 3 (thermal energy) → CaO + CO 2 (Gas)

한편, 본 발명의 내화성 판재조성물은 우수한 내화성능을 확보하였지만 습기에 과다노출시에는 탄화성 섬유에 곰팡이가 발생할 소지가 높고, 경량골재는 흡수율이 높으며, 차콜형성제 중에 규산나트륨 및 규산칼륨은 백화현상이 발생하거나 수분에 반응하여 결합력이 낮아질 우려가 있으므로, 이를 보완하기 위하여 실리콘계 또는 파라핀계의 발수제와 백화방지제인 형석 또는 규불화소다를 소량 혼용하여 사용할 수 있다. 이같은 백화방지제의 첨가시 그 함량은 전체 조성물 중 2중량%를 초과하지 않는 것이 바람직한 바, 그 함량이 2중량%를 초과하게 되면 발수코팅에 의한 사용재료들의 재료분리의 문제가 있을 수 있다. On the other hand, the fire-resistant plate composition of the present invention secured excellent fire resistance, but when exposed to excessive moisture, there is a high possibility of mildew on the carbon fiber, light aggregates have high absorption rate, sodium silicate and potassium silicate in charcoal forming agent whitening Since the phenomenon may occur or the binding force may be reduced in response to moisture, a small amount of silicone or paraffin-based water repellent and fluorite or sodium fluoride may be used in combination. The addition of such anti-whitening agent is preferably not more than 2% by weight of the total composition, if the content exceeds 2% by weight there may be a problem of material separation of the materials used by water repellent coating.

또한, 본 발명의 판재조성물을 제조시에 계면활성제를 사용하면 탄화성 섬유의 표면장력을 낮추어 차콜형성제가 섬유 내부로 균일하게 침투하기가 용이하고, 차콜형성제가 조성물 내부에 균일하게 분포할 수 있다. 계면활성제로는 양이온 계면활성제, 음이온 계면활성제, 비이온 계면활성제 중에서 선택하여 사용할 수 있다. 첨가시 그 함량은 전체 조성물 중 3중량%를 초과하지 않는 것이 바람직하다.In addition, the use of a surfactant in the production of the plate composition of the present invention lowers the surface tension of the carbonizable fiber to facilitate the penetration of the charcoal forming agent evenly into the fiber, the charcoal forming agent can be uniformly distributed in the composition. . As surfactant, it can select from a cationic surfactant, an anionic surfactant, and a nonionic surfactant. When added, the content thereof is preferably not more than 3% by weight of the total composition.

한편, 소재의 혼합 후 건조 경화시에는 시멘트류, 석회류, 석고프라스터, 마그네시아, 이산화탄소 중에서 선택된 1종 이상의 것을 경화제로서 첨가하면 차콜형성제의 경화를 아주 편리하고 급속하게 시킬 수 있다. 경화제의 첨가시 그 함량은 전체 조성물 중 8중량%를 초과하지 않는 것이 바람직하다. On the other hand, in the case of dry curing after mixing the materials, when the at least one selected from cements, limes, gypsum plaster, magnesia, carbon dioxide is added as a curing agent, the curing of the charcoal forming agent can be very convenient and rapid. It is preferable that the content of the curing agent does not exceed 8% by weight in the total composition.

이같은 조성을 갖는 본 발명의 내화성 판재조성물의 화재저항 메카니즘은 다음과 같다; 화재가 발생하여 화재온도가 상승함에 따라 본 발명의 조성물에 포함된 차콜형성제가 판재조성물 내부에 존재하는 탄화성 섬유 표면에 무기질 피막을 형성시켜 화염에 노출시에 착화를 지연 및 방지시키고 탄화성 소재로부터 산소를 차단시켜 단열성이 뛰어난 차콜을 형성하여 내화성 판재조성물의 착화온도를 400-800℃로 상승시킨다. The fire resistance mechanism of the fire resistant plate composition of this invention which has such a composition is as follows; As the fire occurs and the temperature of the fire increases, the char forming agent included in the composition of the present invention forms an inorganic coating on the surface of the carbonizable fiber present in the plate composition, which delays and prevents ignition when exposed to a flame and is a carbonizable material. Oxygen is blocked from forming a charcoal having excellent thermal insulation property, and the ignition temperature of the refractory plate composition is raised to 400-800 ° C.

또한, 탄산암모늄, 탄산수소나트륨 등의 난연제를 첨가함으로써 초기 화재시 100-200℃에서 이들 소재의 분해로 발생하는 불연소성 가스가 가연성 소재(탄화성 섬유)의 연소시 발생하는 가연성 가스의 농도를 저하시켜 착화를 방지할 수 있으며, 탄산칼슘, 탄산마그네슘 등을 첨가함으로써 800℃ 정도에서 분해되는 불연소성 가스로서 고온에서도 화재에 저항할 수 있는 메카니즘을 형성할 수 있다.In addition, by adding a flame retardant such as ammonium carbonate and sodium hydrogen carbonate, the non-combustible gas generated by the decomposition of these materials at 100-200 ° C. during the initial fire can reduce the concentration of the flammable gas generated when the combustible material (carbon fiber) is burned. It is possible to prevent the ignition by lowering, and to add a calcium carbonate, magnesium carbonate or the like, a non-combustible gas that decomposes at about 800 ° C., thereby forming a mechanism that can resist fire at high temperatures.

이하, 내화성 판재 성형품에 대해 실시예를 통해 성능을 확인하고 기존 건축용 판재를 기준으로 한 비교예를 통한 차이점을 시험결과를 통해 상세히 설명하고자 한다. 그러나 이것은 본 발명을 예시하고자 한 것으로서 본 발명이 실시예 및 비교예에 의해 한정되는 것은 아니다. Hereinafter, the performance of the fire-resistant plate molded article will be confirmed in detail through the examples, and the difference through the comparative example based on the existing building plate will be described in detail through the test results. However, this is intended to illustrate the present invention, the present invention is not limited by the Examples and Comparative Examples.

실시예. 내화성 판재의 주 소재별 및 조성 비율별 성능시험Example. Performance test by main material and composition ratio of fireproof plate

경량골재 및 탄화성섬유에 일정한 조성비율별로 차콜형성제를 첨가하여 성능 차이를 확인하기 위하여, 다음 표 1과 같은 조성으로 경량골재로서 팽창퍼라이트와 탄화성 섬유로서 0.1-5mm로 파쇄한 폐신문지 분쇄분을 첨가하고, 여기에 무기충전재로서 탈크를 35중량% 투입하고, 그 나머지를 차콜형성제로서 상온에서 액상인 규산나트륨을 고형분 기준으로 투입하여 시험체 1 내지 4를 제작하였다. 또한, 난연제의 첨가를 통한 내화성능의 향상 정도를 확인하기 위하여 난연제로서 탄산암모늄을 10중량% 첨가한 시험체 5를 제작하였다.In order to check the difference in performance by adding char-forming agent to a certain composition ratio to light aggregate and carbon fiber, waste paper shredded to 0.1-5mm as expanded aggregate and carbonized fiber as light aggregate with the composition as shown in the following Table 1 Powder was added, and 35 wt% of talc was added thereto as an inorganic filler, and the remainder was added to the solid sodium silicate at room temperature as a charcoal forming agent based on solid content, thereby preparing Test Samples 1 to 4. In addition, in order to confirm the degree of improvement of the fire resistance through the addition of a flame retardant, Test Subject 5 was prepared by adding 10% by weight of ammonium carbonate as the flame retardant.

수득한 내화성 판재조성물의 난연성 시험은 KS F 2271(건축물의 내장재료 및 구조의 난연성 시험방법)에 의한 난연등급 시험을 난연성 시험기 및 가스유해성 시험기를 통해 실시하였고, 여기서 내화염성은 내화염시험기를 이용하여 화염에 대한 안전성을 시험하였다. The flame retardancy test of the obtained refractory sheet composition was carried out by flame retardancy tester and gas hazard tester by KS F 2271 (flame retardance test method of building material and structure of building), where flame resistance test was performed using flame tester. The safety against the flame was tested.

위의 시험결과를 보면, 규산나트륨의 양이 5중량%일 경우 난연3급을 획득하였으나, 일부연기가 발생하여, 차콜형성제가 탄화성 섬유의 차콜화를 완전하게 형성하지 못한 것을 확인하였다. 그러나, 난연3급의 성능은 최소한의 난연제로서 인정되는 제품으로, 보다 강화된 화재저항성능이 요구되지 않는 부위에서는 난연3급의 성능으로도 사용가능하다. 그러나, 차콜형성제의 양이 5 중량% 미만일 경우, 상기 목적에 부합되는 판재조성물을 얻지 못하는 것으로 나타났다.In the above test results, when the amount of sodium silicate was 5% by weight, flame retardant grade 3 was obtained, but some smoke occurred, and it was confirmed that the char forming agent did not completely form charcoalization of the carbonizable fiber. However, the performance of flame retardant grade 3 is recognized as the minimum flame retardant, and can be used as the flame retardant grade 3 performance in areas where the enhanced fire resistance performance is not required. However, when the amount of the char-forming agent is less than 5% by weight, it was found that a plate composition which does not meet the above purpose is obtained.

또한, 차콜형성제의 양이 25중량%일 경우, 난연성능은 난연1급으로 충분한 내화성능을 확보하였으나, 밀도가 무거워 경량벽체로서의 성능 발휘의 이점을 다소 상실하는 것으로 확인되었다. 따라서, 차콜형성제는 경량골재 및 탄화성섬유의 조성량에 따라 일부 변화가 있으나, 전체 조성물을 기준으로 5-25 중량%이어야만 충분한 가연성 소재의 충분한 차콜화를 통한 상기 목적에 부합되는 내화성 판재조성물을 제조할 수 있는 것으로 나타났다. In addition, when the amount of the char-coating agent is 25% by weight, the flame retardant performance was obtained as a flame retardant class 1, but sufficient fire resistance, but it was confirmed that the density is heavy and loses the advantage of the performance as a lightweight wall somewhat. Accordingly, the charcoal forming agent may have some changes depending on the composition of the light aggregate and the carbonizable fiber, but should be 5-25% by weight based on the total composition of the refractory plate composition which satisfies the above purpose through sufficient charcoalization of sufficient flammable material. It was shown that it can be prepared.

또한, 첨가제로서 난연제를 포함할 경우, 차콜형성제만을 포함한 판재조성물에 비해 강화된 난연성능을 나타냄으로써, 고온 및 저온에서의 화재저항 메카니즘을 효율적으로 이루고 있음을 확인하였다. In addition, when the flame retardant is included as an additive, the flame retardant performance is enhanced compared to the plate composition including only the charcoal forming agent, and it was confirmed that the fire resistance mechanism at high and low temperatures is achieved efficiently.

또한, 차콜형성제와 탄화성 섬유를 달리하여 제조하여 동일한 성능을 발휘하는지 여부를 확인하였다. 시험체 2와 4의 배합을 적용하고, 차콜형성제로서 규산나트륨을 제외하고 인산알루미늄[Al2O3·(P2O5)·6(H2O)]으로 대체하여 시험체 6, 7번을 제조하였고, 시험체 2의 배합에서 탄화성 섬유로서 폐신문지 파쇄분을 0.1-5mm 폴리에스테르섬유로 대체하여 시험체 8번을 제작하여 성능시험을 하였다. 이에 대한 성능시험결과는 다음 표 2와 같으며, 차콜형성제와 탄화성섬유의 변화에 따른 성능은 동일함을 확인하였다.In addition, it was confirmed whether the charcoal former and the carbonizable fiber produced differently to exhibit the same performance. Test compound Nos. 6 and 7 were applied by applying the formulations of Test Samples 2 and 4 and replacing with aluminum phosphate [Al 2 O 3 · (P 2 O 5 ) .6 (H 2 O)] except sodium silicate as charcoal former. The test piece No. 8 was manufactured by replacing the waste paper shredded paper with 0.1-5mm polyester fiber as a carbonizable fiber in the test compound 2 and performing a performance test. The performance test results are as shown in Table 2 below, and the performance according to the change of the charcoal former and the carbonizable fiber was confirmed to be the same.

또한, 주소재인 경량골재와 무기충전재의 변화에 의한 판재조성물의 성능을 확인하기 위하여, 다음 표 3 및 4와 같이 시험체를 제작하여 성능시험을 하였다. 이때 첨가제로서 난연제인 탄산암모늄 5%와 경화제로서 석고플라스터 3%, 백화방지제로서 규불화소다 1.5%와 계면활성제 0.5%를 포함하여 제작 및 건조를 용이하게 하였다. In addition, in order to confirm the performance of the plate composition by the change of the light aggregate and the inorganic filler as the address material, the test body was produced as shown in Tables 3 and 4 to perform a performance test. At this time, 5% of ammonium carbonate as an additive, 3% of gypsum plaster as a curing agent, 1.5% of sodium fluoride as an anti-whitening agent and 0.5% of a surfactant were included to facilitate fabrication and drying.
