Description
본 발명은 철 구조물용 내화피복재의 새로운 조성에 관한 것으로 화산재 발포체와 진주암 발포체의 혼합물을 주축으로 구성된 새로운 조성의 내화피복재를 철 구조물의 표면에 피복시켜서 화재 발생 등에 의한 비상시에 철제 구조물을 보호하는 역할을 2 시간 이상 지속되게 함으로써 우수한 내화특성을 나타내는 두께가 얇은 새로운 내화피복재 조성물 및 내화피복재 시공방법에 관한 것이다.
The present invention relates to a new composition of a fireproof coating for steel structures, and to cover the surface of the steel structure of a fireproof coating material having a new composition consisting of a mixture of volcanic ash foam and pearlite foam on the surface of the steel structure to protect the steel structure in case of an emergency due to a fire or the like. The present invention relates to a new thin fireproof coating composition and a method of constructing a fireproof coating which exhibit excellent fire resistance by allowing to be maintained for at least 2 hours.
현대 건축물은 대부분 철골 구조로 형성되며, 여러 가지 방법으로 내화 처리된 건축자재를 사용하고 있음에도 불구하고 화재 발생 시에는 건물 자체가 화재로부터 취약할 수밖에 없다. 따라서 철 구조물에 대한 내화피복재는 화재에 의해 발생되는 높은 열이 철 구조물에 대하여 전달되는 것을 차단 내지 지연시킴으로써 철 구조물을 화재로부터 보호한다. 일반적으로 알려진 내화피복의 방법으로는 미리 만들어 둔 내화재를 철 구조물에 부착하는 부착식, 내화재료를 바른 철 구조물이 화재에 노출되면 고열에 의하여 발포하여 단열효과를 일으키는 두꺼운 내화막이 형성되어 단열시키는 발포식, 그리고 미리 조합된 내화재를 일정한 두께로 철 구조물에 뿜거나 발라서 화재 시 내화 작용을 일으키는 뿜칠식 등으로 분류할 수가 있다.Most modern buildings are made of steel structures, and despite the use of fireproof building materials in various ways, the building itself is vulnerable to fire in the event of a fire. Thus, the fire resistant coating for the steel structure protects the steel structure from fire by blocking or delaying the transfer of high heat generated by the fire to the steel structure. Commonly known methods of fireproof coating include an adhesive for attaching a refractory material made in advance to a steel structure, and a thick fireproof film forming a heat insulation effect by foaming due to high heat when the fireproof steel structure is exposed to fire. Formulas and pre-assembled refractory materials can be categorized as spraying or spraying steel structures with a certain thickness to cause fire in the event of fire.
이들 각각은 장단점이 있으며, 미리 만들어 붙이는 부착식은 상대적으로 경제적이나, 연결부위나 고층 건물에 대하여 비효과적이며, 발포식은 무기형 발포단열층인 경우, 상대적으로 단열효과는 우수하나, 발포층의 두께와 밀도를 높이는 데 한계가 있으며, 이 무기형 발포단열층은 고온에서 일정한 시간이 지나면 용융, 붕괴의 가능성이 높아져서 내화 시간에서 한정적인 문제가 있고, 유기형 발포단열층은 일반적으로 발포된 후 온도차에 대해 민감하여 용이하게 균열 상태로 전환되어 무기형처럼 내화 시간에 제한적이다. 그리고 뿜칠식은 상대적으로 제조의 편이성과 경제성이 제고되는 반면에 일반적으로 접착력이 부족하고, 숙련된 접착기술이 필요하다.
Each of them has advantages and disadvantages, and the pre-made adhesives are relatively economical, but they are ineffective for connecting areas or high-rise buildings. The foams are relatively insulated in the case of inorganic foam insulation layers. There is a limit to increase, and this inorganic foam insulation layer has a limited problem in fire time due to the high possibility of melting and decay after a certain time at high temperature, and organic foam insulation layer is generally sensitive to the temperature difference after foaming and is easily cracked. As a weapon, it is limited to fire time. In addition, while the spraying method is relatively easy to manufacture and economical efficiency, the adhesion is generally lacking, and skilled bonding technology is required.
본 발명의 목적은 배경 기술에서 논의된 단점을 모두 검토한 다음, 내화피복재의 조성이 철 구조물에 피복된 후 첫째, 2 시간 이상 내화성능을 나타낼 수 있고, 둘째, 화산재 발포체와 진주암 발포체 등을 각각 혼합하여, 혼합 발포체에 의한 단열효과를 획기적으로 도모하며, 셋째, 부착 능력을 현저하게 증가시키는 능력을 추가하고, 넷째, 시공이 용이하며, 다섯째 내화피복재의 두께가 획기적으로 얇게 처리되도록 하는 내화피복재 조성물을 제공하는 것이다.

In addition, the fireproof coating composition and the fireproof coating construction method of the present invention are excellent in fire resistance and flame retardancy, even if the thickness of the coating on the steel structure can be exhibited sufficient fire resistance performance.
본 발명은 기존의 화산재 및 진주암의 혼합 발포체의 활용에 의하여 단열효과를 상승시키고, 동시에 무기 및 유기물 결합제의 적절한 작용으로 부착력을 증가시키며, 계면활성제 등의 추가로 시공이 용이하게 하며, 결론적으로 내화 성능이 180분 이상 되는 내화피복재 조성물 및 내화피복재 시공방법을 제공하고자 하는 것이다. The present invention increases the thermal insulation effect by utilizing the mixed foam of volcanic ash and pearl rock, and at the same time increases the adhesion by the appropriate action of inorganic and organic binders, and facilitate the construction by the addition of surfactants, etc. It is to provide a fireproof coating composition and a fireproof coating construction method having a performance of 180 minutes or more.
즉, 최근의 관련 기술 등을 보면, 대부분 다수의 재료를 투입하여 복잡하게 처리하고 설명됨으로써 단열효과에 대한 구체적이고 실증적인 결과는 알기 어려운 측면도 있음은 사실이다. 그러므로 이 발명은 이러한 문제점을 고려하여 다수의 내화 재료를 간단한 방법으로 처리하여 부착성과 내화특성이 우수한 두께가 얇은 내화피복재 조성물을 조성하고자 한다.That is, in recent years, the related arts, etc., are complicated and processed by explaining a large number of materials, so that the concrete and empirical results of the insulation effect may be difficult to understand. Therefore, in view of these problems, the present invention is to treat a plurality of refractory materials by a simple method to form a thin fireproof coating composition excellent in adhesion and fire resistance properties.
따라서 내화피복재 원료의 선택과 배합을 간단하게 처리하는 방법을 선택하는 한편, 내화피복재의 두께를 얇게 하며, 높은 내화적 특성과 부착성을 동시에 향상시키는데 중점을 두었고 또, 용이하게 칠 또는 뿜칠하는 방법을 선택하도록 하였다. Therefore, the method of simply selecting the raw material and blending of the fireproof coating material is selected, while the thickness of the fireproof coating material is reduced, and the emphasis is on improving the high fire resistance properties and adhesion at the same time, and the method of easy painting or spraying. To select.
한편, 내화피복재의 실제적인 적용은 H형강과 같은 철 구조물을 선택하여 실시하였다. 내화피복재에 대한 뿜칠방법은 관례에 따라 처리하는데, 하도에는 방청도료를 도포하고, 중도에 우리가 발명한 내화피복재를 칠하거나 뿜칠하고 24시간 정도 건조한 후에, 건조시킨 중도에 재차 칠 또는 뿜칠의 방법으로 피복시켜 상도를 형성하였다.On the other hand, the practical application of fire-resistant cladding was carried out by selecting steel structures such as H-beams. The method of spraying fireproof coatings is treated according to customs.The method is to apply antirust coating to the bottom, coat or spray fireproof coating of our invention in the middle and dry for about 24 hours, and then apply or spray again in the middle of drying. It was coated with to form a top coat.
일반적으로 발포체의 강도(또는 밀도)는 이산화규소의 함량에 비례하는데, 강도가 증가될수록 내화성능이 우수해 진다. 그러므로 산화규소의 함량이 최소 65%인 화산재 발포체와 최소 68%인 진주암 발포체(펄라이트)를 일정한 비율로 혼합한 혼합물은 돌연한 화재발생 시에 발포되는 경우, 또는 화산재 발포체나 진주암 발포체 중 선택된 어느 한 가지 만 사용한 경우보다 투입되는 원재료와 제조과정의 측면에서 경제적이라 할 수 있다.In general, the strength (or density) of the foam is proportional to the content of silicon dioxide, and the higher the strength, the better the fire resistance. Therefore, a mixture of a mixture of volcanic ash foam with at least 65% silicon oxide and pearlite foam (pearlite) with at least 68% content is foamed in the event of a sudden fire, or one selected from volcanic ash or perlite foams. It is more economical in terms of raw materials and manufacturing process than using eggplant alone.
상기의 무기화합물형 발포체는 자기 스스로 부착하는 능력이 없으므로 석고, 포틀랜드, 셀룰로스 등의 결합체룰 추가하여 내화피복재가 원만하게 결합작용을 할 수 있도록 한다. 그리고 여기에 내화 능력이 뛰어난 탄산칼슘과 수산화알루미늄을 가하여 내화강도를 증가시킨다. 그러나 발포체와 내화체 만의 조성으로 내화피복재의 역할을 종결한다면, 부착능력 등의 문제가 남게 되므로 계속하여 히드록시 알킬 셀룰로스, 식초산 비닐, 알킬 설폰산 소다 등을 추가하여 내화피복재의 표면이 균일해 지고 표면적을 증가시켜서 철 구조물의 표면에 대한 부착능력을 증가시킨다. 이들은 유기화합물로서 내화작용에는 직접적으로 관여하지 않으나 반드시 필요한 요소인 것이다. 한편 상기의 조합으로 내화피복재로서 나쁘지 않은 결과를 보이고 있으나, 이들을 H형강과 같은 철 구조물에 실제로 적용하는 경우에 건조시간을 단축해야 한다는 문제가 있으므로 이를 극복하기 위하여 조강재료를 추가해야 한다. 그리고 이들 내화피복재 조성물을 철 구조물에 실제로 사용할 때 용제는 물이며 건조 상태의 내화피복재 조성물과 잘 혼합해야 한다.Since the inorganic compound foam is not capable of attaching itself, it is possible to add a binder such as gypsum, portland, cellulose, and the like, so that the refractory coating material can be smoothly combined. In addition, calcium carbonate and aluminum hydroxide having excellent fire resistance are added to increase the fire resistance. However, if the role of fireproof coating is terminated by the composition of foam and fireproof material alone, problems such as adhesion remain, so that the surface of fireproof coating is uniform by adding hydroxy alkyl cellulose, vinyl vinegar acetate, and alkyl sulfonic acid soda. It increases the surface area of the steel structure to increase the adhesion to the surface of the steel structure. These are organic compounds that are not directly involved in the refractory action but are essential elements. On the other hand, the combination of the above is not a bad result as a fireproof coating, but when they are actually applied to steel structures such as H-beams, there is a problem that the drying time should be shortened, so the steel material must be added to overcome this problem. When these fireproof coating compositions are actually used in steel structures, the solvent is water and must be mixed well with the dry fireproof coating composition.
결론적으로 그 동안 제시되어 온 많은 관련 문헌이나 기술을 검토할 때, 뛰어난 내화 능력과 함께 가장 단순한 조성을 갖으며 처리가 용이한 내화피복재 조성물을 제공하는 것이다.In conclusion, when reviewing a large number of related literatures and techniques that have been presented, it is to provide a fireproof coating composition having the simplest composition and easy treatment with excellent fire resistance.
이제 이 발명을 통하여 제공하고자 하는 내화피복재 조성물 및 내화피복재 시공방법의 특징을 상세하게 설명한다. Now, the characteristics of the fireproof coating composition and the fireproof coating construction method to be provided through the present invention will be described in detail.
철 구조물에 대한 내화피복재 조성물의 주요 부분은 발포체의 존재이다. 발포체의 구성은 이미 공지된 특허나 문헌에 나타난 바와 같이 내화성능이 차별화되는 다양한 조성과 형식으로 되어 있다. 화산재를 950-1100℃에서 처리한 발포체와 진주암을 850-1200℃에서 처리한 발포체를 선택한 후 일정한 비율로 서로 혼합한다. The main part of the fire resistant coating composition for steel structures is the presence of foam. The composition of the foam is in various compositions and forms in which the fire resistance is differentiated, as shown in already known patents and literature. Selected foams treated with volcanic ash at 950-1100 ° C and foams treated with pearlite at 850-1200 ° C are mixed with each other at a constant rate.
즉, 화산재 발포체의 혼합비는 8.6~10.2중량%까지의 범위를 선택하며 바람직하게는 8.8~10.0중량%의 범위를 유지한다. 그리고 진주암 발포체는 그것의 혼합비를 25.2~36.2중량%의 범위로 정하며 바람직하게는 그 혼합비는 27.2~34.2중량%까지의 범위이다. 그러나 화산재 발포체와 진주암 발포체를 혼합할 때 혼합비율을 고려한 그 혼합비의 합은 36.6~44.6중량%까지의 범위이며, 바람직하게는 이 혼합비의 합이 38.6~42.6중량%의 범위가 되도록 한다. 즉, 최적의 구성비율을 유지하는 화산재 발포체와 진주암 발포체의 혼합비를 구체적으로 제공하는 것이다.That is, the mixing ratio of the volcanic ash foam is selected in the range of 8.6 to 10.2% by weight, preferably maintained in the range of 8.8 to 10.0% by weight.

That is, to specifically provide a mixing ratio of the volcanic ash foam and the pearl rock foam to maintain the optimum composition ratio.
그리고 여기에 난연능력이 뛰어난 것으로 알려진 탄산칼슘 및 수산화알루미늄을 추가하여 난연성을 증대시키는데, 탄산칼슘의 혼합비는 2.0~4.3중량%의 범위로 정하되, 바람직하게는 2.4~3.6중량%까지의 범위를 갖는다. 또한, 수산화알루미늄의 경우, 그 혼합비는 6.1~10.4중량%의 범위로 하고, 바람직하게는 8.9~9.9중량%까지로 그 범위를 정한다. 그리고 상기의 탄산칼슘과 수산화알루미늄의 혼합비의 합이 10.5~14.5중량%의 범위 내에서 구성비율을 유지하되, 바람직하게는 탄산칼슘과 수산화알루미늄의 혼합비를 11.5~13.5중량%까지의 범위가 되도록 하는 구성비율을 제공한다.In addition, calcium carbonate and aluminum hydroxide, which are known to be excellent in flame retardancy, are added to increase the flame retardancy. The mixing ratio of calcium carbonate is set in the range of 2.0 to 4.3% by weight, preferably in the range of 2.4 to 3.6% by weight. . In the case of aluminum hydroxide, the mixing ratio is in the range of 6.1 to 10.4% by weight, and preferably in the range of 8.9 to 9.9% by weight.

다음, 혼합된 발포체와 난연재 등은 독자적 능력으로 상호 결합될 수도, 부착될 수도 없으므로 새로운 결합제를 추가해 주어야 한다. 그러므로 상기의 발포체와 난연재 등의 결합제로서 석고, 시멘트, 그리고 펄프 등을 추가하게 되는데, 석고의 경우, 그 혼합비는 12.1~25.3중량%까지의 범위이며, 바람직하게는 14.1~23.3중량%까지의 범위이다. 시멘트의 경우, 그 혼합비는 14.7~22.7중량%까지로서, 바람직하게는 16.7~20.7중량%까지의 범위이다. 그리고 펄프의 경우, 그 혼합비는 5.0~5.6중량%까지로 하되, 바람직하게는 5.2~5.4중량%의 범위를 갖도록 한다. 다만, 상기의 석고, 시멘트, 그리고 펄프의 혼합비의 합은 39.7~45.7중량%까지의 범위로 하되, 바람직하게는 이 혼합비의 합이 40.7~44.7중량%까지의 범위가 되도록 하는 구성비율을 제공한다.Next, the mixed foam and the flame retardant and the like cannot be bonded or attached to each other by their own ability, so a new binder must be added. Therefore, gypsum, cement, and pulp are added as the binder of the foam and the flame retardant. In the case of gypsum, the mixing ratio is in the range of 12.1 to 25.3% by weight, and preferably in the range of 14.1 to 23.3% by weight. to be. In the case of cement, the mixing ratio is up to 14.7-22.7 wt%, preferably in the range up to 16.7-20.7 wt%. And in the case of pulp, the mixing ratio is to 5.0 to 5.6% by weight, preferably in the range of 5.2 to 5.4% by weight. However, the sum of the mixing ratio of the gypsum, cement, and pulp is in the range of 39.7 to 45.7% by weight, preferably providing a composition ratio such that the sum of the mixing ratio is in the range of 40.7 to 44.7% by weight. .
상기에서와 같이 여러 가지의 결합제를 추가함에도 불구하고 부착능력을 보완ㆍ증대시켜야 하는 문제는 여전하게 남게 되므로 계속하여 히드록시 알킬 셀룰로스, 식초산 비닐, 그리고 알킬 설폰산 나토리움 등을 추가하여 내화피복재의 표면을 균일하게 하고 표면적을 증가되도록 하여 내화피복재의 총체적 부착능력을 증가시켜서 철 구조물에 견고하게 부착되도록 한다. 그러므로 히드록시 알킬 셀룰로스의 경우, 그 혼합비를 0.3~0.7중량%의 범위로 하되, 바람직하게는 0.4~0.6중량%까지로 한다. 식초산 비닐의 경우, 0.2~0.4중량%의 범위이며 바람직하게는 그 혼합비를 0.25~0.35중량%까지의 범위로 정한다. 그리고 알킬 설폰산 나토리움은 그 혼합비를 0.2~0.3중량%로 정하되, 바람직하게는 0.25~0.35중량%의 범위를 갖도록 한다. 그러나 상기의 히드록시 알킬 셀룰로스, 식초산 비닐 및 알킬 설폰산 나토리움의 혼합비의 합이 0.9~1.3중량%의 범위 안에 있어야 하는 구성비율을 제공한다.Despite the addition of various binders as described above, the problem of compensating and increasing the attachment capacity still remains, and thus, hydroxy alkyl cellulose, vinyl vinegar acetate, and alkyl sulfonic acid natorium are added to the fireproof coating material. To make the surface uniformly and increase the surface area, increase the overall adhesion capacity of the fireproof coating material to be firmly attached to the steel structure. Therefore, in the case of hydroxy alkyl cellulose, the mixing ratio is in the range of 0.3 to 0.7% by weight, preferably 0.4 to 0.6% by weight. In the case of vinyl vinegar acetate, it is the range of 0.2 to 0.4 weight%, Preferably the mixing ratio is set to the range of 0.25 to 0.35 weight%. And the alkyl sulfonic acid natriumum is set to 0.2 to 0.3% by weight of the mixing ratio, preferably to have a range of 0.25 to 0.35% by weight. However, it provides a composition ratio in which the sum of the mixing ratios of the above hydroxy alkyl cellulose, vinyl vinegar acetate and alkyl sulfonic acid nathium should be in the range of 0.9 to 1.3% by weight.
상기의 조합으로 내화피복재로서 나쁘지 않은 결과를 보이고 있으나, 이들을 H형강과 같은 철 구조물에 실제로 적용하는 경우에 건조시간을 단축해야 하는 문제가 있으므로 이를 극복하기 위하여 조강재를 추가하며 그 혼합비는 2.3~4.3중량%의 범위로 하되, 바람직하게는 2.6~3.6중량%의 범위로 그 구성비율을 제공한다. Combination of the above shows a bad result as a fireproof coating, but when they are actually applied to steel structures such as H-shaped steel, there is a problem to shorten the drying time, so to add a steel bar to overcome this, the mixing ratio is 2.3 ~ 4.3 It is in the range of% by weight, preferably provides the composition ratio in the range of 2.6 to 3.6% by weight.
상기의 건조된 분말상태의 구성 물질은 내화피복재이며, 고유한 혼합비에 따라서 조성된 내화피복재는 시공 직전 물과 함께 잘 교반한 후 사용한다. 이 때, 물의 혼합비는 건조 분말상태의 내화피복재 조성물 전체에 대하여 1.1~1.5중량%의 범위로 하되, 바람직하게는 1.2 ~1.4중량%의 범위 내에서 잘 혼합되어야 한다.The dried powdery constituent material is a fireproof coating material, and the fireproof coating material formed according to a unique mixing ratio is used after stirring well with water just before construction. At this time, the mixing ratio of water is in the range of 1.1 to 1.5% by weight based on the entire dry coating of the fireproof coating composition, preferably should be well mixed within the range of 1.2 to 1.4% by weight.
이 발명의 내화피복재 조성은 다양하지도 복잡하지도 않다. 주 대상은 H형강과 같은 철 구조물이며, 뿜칠이나 칠도 단 두 번이면 족하다. 시공 시에 먼지도 거의 나지 않는다. 조성에 포함되는 모든 원료는 환경 친화적이며, 인체에 무해하고 구득이 용이하다. 특히 내화피복재의 두께가 동류의 어느 제품보다도 얇은 것이 큰 특징으로서, 한마디로 완벽한 경제적인 조성이라고 할 수 있는 것이다. 또한 이 내화피복재는 건설교통해양부 고시(제2005-122호) 기준에 의한 내화시험방법에 따라 시험되었다. The fireproof coating composition of this invention is neither diverse nor complicated. The main target is steel structures such as H-beams, and only two sprays and paints are needed. There is little dust at the time of construction. All raw materials included in the composition are environmentally friendly, harmless to humans, and easy to obtain. In particular, the thickness of the fireproof coating material is thinner than any other products of the same kind, which is a perfect economic composition. In addition, this fireproof cladding was tested in accordance with the fire resistance test method according to the notice of the Ministry of Construction and Transportation (2005-122).
