커튼월(curtain wall)은 장막벽이라고도 하는 비내력 외주벽으로, 철근콘크리트조, 철골조, 철골철근 구조에서 기둥, 보, 바닥판으로 형성되는 구조부(frame)의 외부를 금속재 또는 무기질 재료로써 공간을 막아내는 비내력벽(non bearing wall)을 말한다. 종전의 습식공법의 외장 시스템에 비해 경량이기 때문에 건축물 전체의 중량이 줄어 주요 구조체에 하중을 경감시키며, 동시에 결제적 설계가 가능하며, 공정에서 반입하는 Pre-Fab 또는 Pre-assembly 제품이기 때문에 기초 또는 골조공사 시점부터 선제작이 가능하여 구조체가 완성되는 즉시 취부 할 수 있으므로 현장작업의 간소화 및 공기를 단축할 수 있고, 공장제작에 의한 품질의 균질성을 확보할 수 있을뿐만 아니라, 건축물의 디자인을 다양화 할 수 있고 현장시공의 기계화 등의 장점이 있어 최근 커튼월에 의한 시공이 활발히 이루어지고 있다. 커튼월의 종류는 구조방식에 따라 멀리언 방식과 스팬드럴 방식으로 구분되며, 그 중 스팬드럴방식은 커튼월의 외관으로 볼 때 건축물의 층간 부분의 조망 불가능한 부분을 말하며, 이 부분에 설치된 부분은 스팬드럴(Spandrel)유리 또는 스팬드럴 패널이라고 말한다. 종래 스팬드럴 부분은 커튼월 건축물의 벽체 중 단열재의 시공이 가능한 부분으로서 주로 글라스울이나 미네랄울 등의 단열재를 사용하여 왔으나 글라스울이나 미네랄울은 취급상의 문제점과 단열성능의 미흡함 특히 수분의 취약함으로 인한 결로 발생 등으로 보다 고성능이고 취급이 간단한 커튼월의 스팬드럴용 단열재가 요구되어 왔다. A curtain wall is a non-bearing outer wall, also called a curtain wall, which is a metal or inorganic material that forms the exterior of a frame formed of columns, beams, and bottom plates in reinforced concrete, steel, and steel structures. It refers to a non bearing wall that is blocked. Since it is lighter than the conventional wet process exterior system, the weight of the whole building is reduced to reduce the load on the main structure, and at the same time, it is possible to settle the billing design. Prefabrication is possible from the point of frame construction, so it can be mounted as soon as the structure is completed, which simplifies the field work and shortens the air, secures the homogeneity of the quality by factory production, and also varies the design of the building. The construction of the curtain wall has been actively performed since there are advantages such as mechanization of the field construction. The types of curtain wall are divided into mullion method and spandral method according to the structural method. Among them, the spandral method refers to the unviewable part of the interlayer part of the building from the exterior of the curtain wall. It is called Spandrel glass or spanned panel. Conventional part of the wall of the curtain wall building is a part that can be used for the construction of the insulation material, mainly glass wool or mineral wool insulation materials, but glass wool or mineral wool is a problem of handling and lack of insulation performance, especially because of weak water Due to condensation, etc., a higher performance and simpler handle for insulation of a curtain wall has been required.
본 발명에 의한 진공단열재는 '건축물 에너지절약 설계기준'의 '가'등급 단 열재 대비 매우 우수한 열전도율을 보이므로 낮은 단열재 두께로 시공하여도 '건축물의 설비기준 등에 관한 규칙'에서 정하고 있는 건축물 부위의 열관류율(창 및 문) 기준이상 만족하며, 기존 유기계(폴리우레탄)의 화재에 취약한 단점을 무기계 재료로 난연성능을 확보하였으며, 필름 랩핑후 가스차단필름으로 진공 포장을 하여 최종 마감포장 한 것으로 기존 무기계(그라스울)의 취약점인 흡습성을 개선하였으며, 실리카 분체 등의 친환경 원료로 취급시에도 기존 그라스울 대비 따갑거나, 냄새가 나는 등에 대해 문제가 전혀 없는 커튼월의 스팬드럴에 적용하는 불연 단열재 및 이의 제조방법에 관한 것이다.The vacuum insulation material according to the present invention shows a very excellent thermal conductivity compared to the 'a' grade insulation material of the 'building energy saving design standard', so even when the construction is made with a low insulation thickness, It satisfies the criteria of heat permeability (window and door), and has the disadvantage of vulnerable to fire of existing organic type (polyurethane). It has secured flame retardant performance with inorganic material, and finally wrapped by vacuum packing with gas barrier film after wrapping film. Non-flammable insulation and its manufacturing method have been improved for hygroscopicity, which is a weak point of (Glass Wool), and applied to the curtain wall of the curtain wall, which has no problems with the smell or smell compared to the existing glass wool even when handled as an eco-friendly raw material such as silica powder. It is about.
본 발명의 커튼월의 스팬드럴 패널에 적용하는 진공 단열재는 열전도율 값이 상기에서 구분되어 지고 있는 가장 최고등급의 '가'(열전도율값 0.034W/mK 이하)등급의 단열재들 보다 월등히 뛰어난, 열전도율 값이 약 1/6 수준인 0.005W/mK 이하의 성능을 발휘하는 고성능의 단열재로 기존의 적용되었던 단열재 두께보다 절반 이하의 두께로 시공하여도 동등수준 이상의 열관류율 성능확보가 가능하다. The vacuum insulation material applied to the spandal panel of the curtain wall of the present invention has a thermal conductivity value that is much better than those of the highest grade 'ga' (thermal conductivity value of 0.034 W / mK or less), which is classified above. This is a high-performance heat insulator with a performance of less than 0.005W / mK, which is about 1/6, and even if it is less than half the thickness of the existing heat insulator, it is possible to secure the equivalent heat transfer rate.
법규 기준인 '건축물의 설비기준 등에 관한 규칙'에서 정하고 있는 '지역별 건축물 부위의 열관류율표'에 따르면 건축물 부위중 '창 및 문'은 공동주택 및 공동주택 외, 그리고 외기에 직접 면하는 경우와 외기에 간접 면하는 경우에 대해서 중부지역, 남부지역, 제주도 총 세곳의 지역별로 건축물의 단열성능에 따른 열관류율 기준을 두고 있으며, '창 및 문'에 대한 건축물 부위별 열관류율 값이 가장 낮은 경우는 중부지역에서 외기에 직접 면하는 공동주택의 경우(3.00 W/㎡K 이하)이다.According to the `` Regional Heat Transfer Rate Table of Building Parts by Region '', which is defined in the `` Regulations on Equipment Standards of Buildings, '' which are legal standards, `` windows and doors '' of building parts are directly outside apartment buildings and apartment houses, and directly outside the outside air and outside air. In case of facing indirectly, the heat transfer rate based on the thermal insulation performance of the building is based on the three regions of Central, Southern, and Jeju islands. This is the case for apartment houses directly facing the outside air (3.00 W / ㎡K or less).
상기의 기준은 건축설비의 설치에 관한 기술적 기준과 건축물의 열손실방지 및 에너지의 합리적인 이용 등에 관하여 필요한 사항을 규정한 것으로써, 상기에 기술한 '창 및 문'에 대한 열관류율 값(3.00 W/㎡K 이하)은 과거 기준(3.84 W/㎡K 이하)에서 2008년 7월 10일 강화되어 개정된 사항으로 향후 지속적인 건축물의 부위별 열관류율 값이 건축물의 열손실방지에 따라 지속적으로 강화되는 바, 스팬드럴 부위에 적용되는 단열재도 지속적인 성능 향상이 필요한 실정이다. The above criteria stipulates the technical standards for the installation of building equipment and the matters necessary for the prevention of heat loss of buildings and the rational use of energy, and the values of heat permeability for 'windows and doors' described above (3.00 W / ㎡K and below) was revised on July 10, 2008 from the previous standard (3.84 W / ㎡K and below), and the value of heat permeation rate for each part of the building will be continuously strengthened in accordance with the prevention of heat loss of the building. Insulation material applied to the spandral region also needs a continuous improvement of performance.
통상적으로 현재 스팬드럴의 단열재로 그라스울 또는 미네랄울이 가장 많이 적용되나, 그라스울이나 미네랄울은 무기계의 불연재이나 취급시 그라스울이 피부에 접촉되어 따갑고 이에 따라 사용자들이 사용을 기피하며, 습기에 의한 경시변화가 취약하여 열전도율 값이 저하되거나, 또한 그라스울에 수분이 침투하여 그라스울 형태가 변형되어 스펜드럴 내부에서 빈 공간이 발생되어 그라스울에 대한 단열성능에 문제가 발생할 수 있으며, 그라스울 바인더에 포함되어 있는 우레아 수지가 수분과의 반응으로 암모니아 냄새를 발생시켜 환경적으로 또한 문제가 야기될 소지가 있다. 또한 스팬드럴 부위의 열 손실과 결로 발생 등 여러 문제가 발생할 수 있다.In general, glass wool or mineral wool is most commonly used as a thermal insulation material of spandral, but glass wool or mineral wool is inflammable of inorganic type and glass wool is brought into contact with skin when handled, and thus users avoid using it and change with time due to moisture. Vulnerable to low thermal conductivity value, or moisture penetrates into glass wool and deforms the glass wool to create empty space inside the spiral, which may cause problems in insulation performance against glass wool, and urea resin contained in glass wool binder There is a possibility that the reaction with moisture generates ammonia odor, which causes environmental problems as well. In addition, various problems may occur such as heat loss and condensation in the spandral region.

이와 같은 본 발명을 상세하게 설명하면 다음과 같다.The present invention will be described in detail as follows.
본 발명에서 사용되는 실리카 분체는 무정형의 매우 가벼운 분말로 기본입자가 극히 작고 구형의 형태이며 넓은 표면적과 특유의 표면 특성, 그리고 고순도의 규소화합물로서, 구형의 기본입자의 평균직경은 5 ~ 50 ㎚ 의 크기를 가지고 있으며, 입자가 작음으로 인해 넓은 표면적을 가지며 그 값은 40 ~ 400 ㎡/g 의 범위에 이르는 분말 형태이다.The silica powder used in the present invention is an amorphous, very light powder with very small basic particles, a spherical shape, a large surface area, a characteristic surface characteristic, and a high purity silicon compound. The average diameter of the spherical basic particles is 5 to 50 nm. It has a size of, and has a large surface area due to the small particles, the value is in the form of a powder ranging from 40 to 400 m 2 / g.
실리카 분체는 실리카 단열재의 전체 조성물 중에 40 ~ 99 중량%를 사용한다. 그 사용량이 40 중량% 미만이면 상대적으로 KS L 9016 보온재의 열전도율 측정방법에 의거하여 측정한 열전도율값이 0.005W/mK 이상으로 되어 단열 성능이 저하되는 문제점이 있으며, 99 중량%를 초과하는 경우에는 성형체의 가장자리 부위의 형태가 저하되는 성형성의 문제점이 있다.Silica powder is used 40 to 99% by weight in the total composition of the silica insulation. If the amount is less than 40% by weight, the thermal conductivity value measured according to the thermal conductivity measurement method of KS L 9016 thermal insulation material becomes 0.005W / mK or more, and the insulation performance is deteriorated. There is a problem in moldability that the shape of the edge portion of the molded body is lowered.
본 발명에서 사용되는 보강 섬유는 무기 섬유 또는 유기 합성 섬유를 사용하 며, 직경 2 ~ 15 ㎛, 길이 6 ~ 20 ㎜ 인 섬유를 사용하며, 무기 섬유는 유리 섬유 및 세라믹 섬유를 사용하고, 유기 합성 섬유는 PAN, PVA, PP, Nylon 등의 섬유를 사용한다.As the reinforcing fibers used in the present invention, an inorganic fiber or an organic synthetic fiber is used, and a fiber having a diameter of 2 to 15 μm and a length of 6 to 20 mm is used, and the inorganic fiber uses glass fiber and ceramic fiber, and an organic synthetic As the fiber, fiber such as PAN, PVA, PP, or Nylon is used.
보강 섬유는 0.5 ~ 20 중량%를 사용한다. 그 사용량이 0.5 중량% 미만이면 보강 섬유에 의한 강도 발현 효과 및 성형성이 저하되는 문제점이 있으며, 20 중량%를 초과하는 경우에는 상대적으로 KS L 9016 보온재의 열전도율 측정방법에 의거하여 측정한 열전도율값이 0.005W/mK 이상으로 되어 단열 성능이 저하되는 문제점이 있다. 또한 길이 6 ㎜ 미만의 섬유를 사용시에는 섬유에 의한 보강 효과가 떨어지며, 길이 20 ㎜ 초과의 섬유를 사용시에는 실리카 분체 등과의 건식혼합시에 섬유의 분산이 어렵고, 섬유 자체의 뭉침현상이 발생하여 제품 성형성이 저하되는 문제를 발생시킨다. Reinforcing fibers use from 0.5 to 20% by weight. If the amount is less than 0.5% by weight, there is a problem in that the strength expression effect and formability by the reinforcing fiber is lowered, and when it exceeds 20% by weight, the thermal conductivity value measured based on the method of measuring the thermal conductivity of KS L 9016 thermal insulation material is relatively high. This becomes 0.005 W / mK or more, and there exists a problem that heat insulation performance falls. In addition, when the fiber length of less than 6 mm is used, the reinforcing effect of the fiber is inferior. When the fiber length of 20 mm or more is used, the fiber is difficult to disperse during dry mixing with silica powder or the like. A problem arises in that moldability deteriorates.
보강 섬유는 고루 분산되어 실리카 분체 응집체와의 일체화된 결합체를 형성하여, 본 단열재의 일차적인 성형성 및 강도 증진 효과를 발휘 하는 것을 목적으로 하며 무기 섬유와 유기 합성 섬유의 혼용섬유 또는 유기 합성 섬유를 단독으로 사용할 수 있다.The reinforcing fibers are evenly dispersed to form an integrated bond with the silica powder aggregate, and the primary purpose is to exert the primary formability and strength enhancing effect of the present heat insulating material. Can be used alone.
본 발명에서 사용되는 첨가제는 필러(충진제)로 불투명화제를 사용한다. 불투명화제는 활석, 탄화규소, 산화티탄, 산화철, 산화지르코늄, 흑연 등을 사용하며, 0 ~ 50 중량%를 사용한다. 50 중량%를 초과하는 경우에는 상대적으로 KS L 9016 보온재의 열전도율 측정방법에 의거하여 측정한 열전도율값이 0.018W/mK 이상으로 되어 단열 성능이 저하되는 문제점이 있다.The additive used in the present invention uses an opaque agent as a filler (filler). The opacifying agent uses talc, silicon carbide, titanium oxide, iron oxide, zirconium oxide, graphite, and the like, and 0 to 50% by weight. If the content exceeds 50% by weight, the thermal conductivity value measured based on the thermal conductivity measurement method of KS L 9016 thermal insulation material becomes 0.018 W / mK or more, which causes a problem of deterioration of thermal insulation performance.
본 발명에서 사용되는 6면 랩핑(Wrapping) 포장에는 PE 필름 또는 LDPE 등의 수축필름을 사용하며, 랩핑(Wrapping) 포장은 1회 또는 2회 실시한다. PE 필름포장은 실리카 단열재 성형체를 PE 필름으로 감싸주고 열접착으로 씰링 처리하며, LDPE 등의 수축필름 포장은 실리카 단열재 성형체를 LDPE 등의 수축필름으로 감싸주고 수축포장기를 이용하여 수축포장한다. In the present invention, the six-side wrapping (wrap) packaging uses a shrink film such as PE film or LDPE, and wrapping is carried out once or twice. PE film packaging wraps the silica insulation molded body with PE film and seals it with heat bonding, and shrink film packaging such as LDPE wraps the silica insulation molded body with shrink film such as LDPE and shrink wraps it using a shrink wrap machine.
본 발명에서 최종 마감재로 사용되는 가스차단필름은 두께 40 ㎛ ~ 250 ㎛ 의 필름을 사용하며, 최종 마감 포장은 진공포장을 하여 열접착으로 씰링 처리하여 마감한다.Gas barrier film used as the final finishing material in the present invention uses a film having a thickness of 40 ㎛ ~ 250 ㎛, the final finishing packaging is sealed by heat sealing by vacuum packaging.
