Abstract
Description
본 발명은 건축용 단열재에 관한 것으로서, 보다 상세하게는 불연성을 갖는 무기질 단열재에 관한 것이다. The present invention relates to a heat insulating material for construction, and more particularly to an inorganic heat insulating material having a non-combustible.
현재 국내에서 사용되는 불연, 단열재는 석고보드, 스치로폼, 글라스울 또는 세라믹화이버 등 유기화학 제품이 사용되고 있는 실정이다.Currently, non-combustible and heat-insulating materials used in Korea are currently using organic chemical products such as gypsum board, styrofoam, glass wool, or ceramic fibers.
이러한 유기화학 제품은 화재발생시 쉽게 타버리고, 유독가스가 발생하여 질식사 및 인명, 재산손실을 감수하여야 했으며 불연재 및 단열재 등 건자재 개발의 요구는 끝없이 재기되어 왔지만 이에 적합한 자재의 기술은 경제성, 시공성 등 여러 문제점으로 한계점에 다다르고 있다.These organic chemical products were easily burned in the event of fire, toxic gas was generated, and it was necessary to take asphyxiation, loss of life, and property loss. The demands for the development of building materials such as non-combustible materials and insulation materials have been recovered endlessly. The problem is reaching its limit.
또한 건축에 사용되는 단열재인 스치로폼.유리섬유.우레탄.암면등은 그동안 산업전반에 걸쳐 널리 사용되었던 소재이었으나 지구온난화 및 환경파괴의 주범으로 앞으로는 이러한 소재로 만든 제품으로는 소비자에게 외면을 받을 것이다.In addition, the insulation materials used in construction, such as Styrofoam, glass fiber, urethane, and rock wool, have been widely used throughout the industry. However, as the main culprit of global warming and environmental destruction, products made from these materials will be turned away from consumers.
특히 스치로폼 페기물은 땅속에서 썩는데 500년이나 걸리고 연소시 많은 유독성가스를 발생하는 단점이 있다.In particular, Styrofoam waste takes 500 years to decay in the ground and generates many toxic gases during combustion.
우레탄폼은 이소시아네이트와 폴리올 등과 혼합하여 현장에서 분사발포하여 공백을 메우거나 또는 판재로 성형하여 사용하나 프레온,펜탄,이산화탄소를 함유하고 있어 환경공해적인 측면에서 매우 부적절한 재료로 입증되었으며, 마르면 부서지는 단점등으로 근래에는 사용되지 않는 경향이 있다.Urethane foam is mixed with isocyanate and polyol and sprayed in the field to fill the blank or molded into a sheet, but it contains freon, pentane and carbon dioxide, which proved to be very inadequate for environmental pollution. In recent years, it is not used.
유리섬유 또한 단열성과 가공성이 좋으나 취급시 미세한 분진등으로 산업병을 일으키므로 이것을 취급하는 인력이 기피하는 현상이 있고 페기물처리시 환경에막대한 피해를 입히고 있다.Glass fiber also has good thermal insulation and processability, but it causes industrial illnesses due to fine dust when handling, which avoids manpower handling and damages the environment during waste disposal.
상술한 종래의 문제점을 해결하기 위한 본 발명의 목적은, 불에 타지 않으며 화재발생시 인명과 재산을 보호하고 단열성능을 발휘하고 가볍고 가공성이 뛰어난 경량 불연 단열재를 제공함에 있다.An object of the present invention for solving the above-mentioned problems is to provide a light-weight non-combustible heat insulating material that is not burned, protects life and property in the event of a fire, exhibits heat insulating performance, and is light and excellent in workability.
상술한 바의 목적을 달성하기 위한 본 발명에 따른 불연성 무기질 단열재는 유리질암석을 870 내지 900℃로 CO2 가스로 급속 가열하여 결정수를 기화시킨 무기질 발포체와; 물유리(Na20·SiO2), 난연제 및 안티몬을 교반한 보조재;를 혼합하여 몰드에 성형하여 열경화시켜 생성된다.Non-combustible inorganic insulating material according to the present invention for achieving the above object is CO 2 to 870 to 900 ℃ glass rock Inorganic foams which vaporize the crystal water by rapid heating with a gas; Water glass (Na 2 O.SiO 2 ), a flame retardant and an antimony stirred auxiliary material; is formed by mixing in a mold and thermoset.
여기서, 상기 무기질 발포체와 보조재의 혼합비율은 2:1인 것이 바람직하다.Here, the mixing ratio of the inorganic foam and the auxiliary material is preferably 2: 1.
여기서, 상기 보조재는 물유리 65 내지 70 중량%, 난연제 27.5 내지 32.5 중량% 및 안티몬 2.5 내지 3.5 중량%의 비율로 교반되게 하는 것이 더 바람직하다.Here, it is more preferable that the auxiliary material is stirred at a ratio of 65 to 70% by weight of water glass, 27.5 to 32.5% by weight of flame retardant, and 2.5 to 3.5% by weight of antimony.
여기서, 상기 보조재는 물유리 67중량%, 난연제 30중량% 및 안티몬 3중량%의 비율로 교반되는 것이 더 더욱 바람직하다.Here, the auxiliary material is more preferably stirred at a ratio of water glass 67% by weight, flame retardant 30% by weight and antimony 3% by weight.
여기서, 상기 불연성 무기질 단열재는 천정재, 방음재, 드라이비트용 단열재, 샌드위치판넬 충진재 또는 건축물의 내외장재로 사용된다. Here, the non-combustible inorganic insulating material is used as a ceiling material, sound insulation, dry bit insulation, sandwich panel filling or interior and exterior materials of buildings.
본 발명에 따른 불연성 무기질 단열재는 건축물의 내·외장 또는 천정재, 방음재, 충진재로 사용되는 건자재이다.Non-flammable inorganic insulating material according to the present invention is a building material used as interior, exterior or ceiling of a building, soundproofing material, filling material.
본 발명에 따른 불연성 무기질 단열재는 유리질암석을 870 내지 900℃로 CO2 가스로 급속 가열하여 결정수를 기화시킨 무기질 발포체와, 물유리(Na20·SiO2), 난연제 및 안티몬을 교반한 보조재를 혼합하여 몰드에 성형하여 열경화시켜 제조된다.Non-combustible inorganic insulation according to the present invention is a CO 2 to 870 to 900 ℃ glass rock An inorganic foam obtained by evaporating crystal water by rapid heating with a gas, and an auxiliary material obtained by stirring water glass (Na 2 O.SiO 2 ), a flame retardant, and antimony is mixed, molded into a mold, and thermally cured.
여기서, 무기질 발포체는 질석, 화강암 또는 화산암 등의 용암이 급속냉각되어 생성된 결정수(약 3%~5%)를 함유한 유리질암석인 무기질을 정석 가공한 후 870℃~900℃의 온도에서 co2 가스로 급속 가열한 후, 급속 가열과정에서 결정수가 기화되면서 무기질을 팽창시키고 백색으로 변하면서 다공성 입자를 형성한 물체로 변하게 되며, 이 다공성 입자의 물체가 무기질 발포체가 된다.Here, the inorganic foam is cobalt at a temperature of 870 ℃ to 900 ℃ after crystallizing minerals, which are glass rocks containing crystallized water (about 3% to 5%) generated by rapid cooling of lava such as vermiculite, granite or volcanic rock. After rapid heating with 2 gas, the crystal water is evaporated in the rapid heating process to expand the inorganic matter, turn white, and turn into an object that forms porous particles, and the object of the porous particles becomes an inorganic foam.
이렇게 얻은 무기질의 특성은 초경량성을 지니게 되며, 밀도 0.04~0.20g/m²를 유지하며, 단열성면에서 열전도율 0.025~0.045kcal/mhc을 갖게되어 우수한 단열 효과를 가지게 되고, 형태 및 질이 변하지 않고, 용융온도 1200℃~1300/연화개시1100℃의 내화성을 지닌다. 또한, 화학적 안정성이 뛰어나 황산, 질산, 수산화나트륨 등의 화학약품에 의한 손상이 전혀 발생되지 않는다. 또한, 6.5~7.5의 경도로 아주 탁월하고 인체나 환경에 전혀 무해하며, 연소시 가스가 발생되지 않는 장점을 갖는다.The inorganic properties thus obtained are ultra-light, maintain density 0.04 ~ 0.20g / m², have thermal conductivity 0.025 ~ 0.045kcal / mhc in terms of heat insulation, and have excellent heat insulation effect, do not change shape and quality, Melting temperature 1200 ℃ ~ 1300 / softening start 1100 ℃ In addition, it is excellent in chemical stability and no damage is caused by chemicals such as sulfuric acid, nitric acid, sodium hydroxide and the like. In addition, the hardness of 6.5 ~ 7.5 is very excellent, harmless to the human body or the environment, and has the advantage that no gas is generated during combustion.
이렇게 생성된 무기질 발포체에 보조제를 첨가하여 혼합한 후 몰드 성형을 거쳐 경화시킨다.An auxiliary agent is added to the inorganic foam thus produced, mixed, and cured through mold molding.
여기서, 첨가되는 보조제는 물유리(Na20·SiO2) 및 친환경 난연제 및 안티몬이 선택된다.Here, the adjuvant to be added is water glass (Na 2 0 · SiO 2 ) and environmentally friendly flame retardant and antimony.
여기서, 무기질 발포체와 보조제의 혼합비율은 2:1로 교반하는 것이 바람직하다.Here, the mixing ratio of the inorganic foam and the auxiliary agent is preferably stirred at 2: 1.
또한, 보조제의 혼합비율은 물유리(Na20·SiO2) 65 내지 70 중량%, 난연제 27.5 내지 32.5 중량% 및 안티몬 2.5 내지 3.5 중량%의 비율로 교반시키는 것이 바람직하다.In addition, the mixing ratio of the auxiliary agent is preferably stirred at a ratio of 65 to 70% by weight of water glass (Na 2 0 · SiO 2 ), 27.5 to 32.5% by weight of flame retardant, and 2.5 to 3.5% by weight of antimony.
물유리는 접착/접합제로서의 기능을 가지며, 65중량% 미만이면 건조시간이 증가됨으로 인하여 생산성 등의 저하를 가져오고, 70중량%를 초과하면 다른 혼합제와 혼합이 잘 안되는 문제점이 있다.Water glass has a function as an adhesive / bonding agent, and if less than 65% by weight, the drying time is increased, resulting in a decrease in productivity, etc., and if it exceeds 70% by weight, there is a problem in that mixing with other mixtures is difficult.
