Description

진공단열재가 내장된 건축용 단열블록 및 그 제조방법{Insulating Block for Building Having Vacuum Insulation Panel and Manufacturing method the same}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating block for a building,

본 발명은 진공단열재가 내장된 건축용 단열블록 및 그 제조방법에 관한 것으로, 보다 상세하게는 진공단열재의 외피재인 알루미늄 호일을 감싸는 보호막을 구비함으로 알루미늄 호일의 부식을 방지하여 내구성, 강도 및 단열성이 우수한, 진공단열재가 내장된 건축용 단열블록 및 그 제조방법에 관한 것이다.The present invention relates to a heat insulating block for building having a vacuum insulator and a method of manufacturing the same, and more particularly, to a heat insulating block for a building having a durable, strength and heat insulating property by preventing a corrosion of an aluminum foil by providing a protective film for covering an aluminum foil , A heat insulating block for building having a vacuum insulating material, and a manufacturing method thereof.

진공단열재(vacuum insulation)는 냉동기나 냉장고와 같은 가전 냉장기기의 에너지 효율 증진과 공간 절감을 위한 목적으로 사용되어 왔다.Vacuum insulation has been used for the purpose of energy efficiency improvement and space saving of household refrigeration appliances such as refrigerator and refrigerator.

진공단열재의 단열성능은 기존 단열재 보다 5~8배가 높아 단열 두께를 얇게 유지하며 높은 단열 성능을 유지하는데 유리하다.The insulation performance of vacuum insulation is 5 ~ 8 times higher than that of existing insulation, so it is advantageous to keep insulation thickness thin and to maintain high insulation performance.

진공단열패널(vacuum insulation panel: VIP)은 기존의 무기질 단열재나 화학합성단열재에 비해 열전도율이 최대 10분의 1에 불과한 것으로 보고되고 있다.Vacuum insulation panels (VIP) have been reported to have a thermal conductivity of only a tenth of that of conventional inorganic or chemical composite insulation.

이와 같은 진공단열재가 우수한 단열성능을 가짐에 따라 건축물의 단열재로 사용하는 방안이 고려되기 시작하였다.As such a vacuum insulation material has excellent heat insulation performance, a method of using it as a heat insulation material of a building has begun to be considered.

진공단열재를 사용하면 건물의 벽, 지붕, 바닥 등이 고효율의 단열성능을 갖도록 하면서도 공지의 다른 단열재를 사용하는 경우보다 얇은 단열층으로 구성하는 것이 가능하다.When a vacuum insulation material is used, a wall, a roof, a floor, or the like of a building can have a high heat insulation performance, but can be formed of a heat insulation layer thinner than a known insulation material.

최근 제로에너지, 그린, 탄소제로, 지속가능 등의 다양한 명칭이 부여된 건물이 다양하게 소개되고 있는데, 이는 건물에서 에너지 소비를 최소화하고 에너지를 생산하여 건물 자체적으로 에너지를 자립화하기 위한 노력의 일환이라고 할 수 있다.Recently, buildings with various names such as zero energy, green, carbon zero, and sustainability have been introduced, which is part of efforts to minimize energy consumption in the building and to produce energy to make the building self- can do.

이러한 건물을 위해서 에너지 손실을 최소화하고 단열을 보강하는 것이 매우 중요하기 때문에 단열성능이 매우 우수한 진공단열패널이 더욱 주목받고 있다.For this building, it is very important to minimize the energy loss and to reinforce the insulation. Therefore, vacuum insulation panels having excellent insulation performance are attracting more attention.

그러나 진공단열패널을 건축물의 단열재로 사용하기에는 장애요인이 많아 상용화되지 못하고 있는 실정이었다.However, there are many obstacles in using vacuum insulation panels as insulation materials for buildings, and they have not been commercialized.

구체적으로 설명하면, 진공단열패널은 특정 부분에서 손상이 발생 되는 경우 진공손실이 발생 되면서 단열성능이 매우 나빠지고 열관류율이 증가하는 문제점이 있는데 건축물에 시공하는 과정에서 충격을 받거나 사용상의 부주의로 인해 진공단열패널의 손상 가능성이 매우 높다는 것이다.Specifically, in the case of a vacuum insulation panel, a vacuum loss is generated when a specific portion is damaged, and the heat insulation performance is very poor and the heat conduction ratio is increased. In the process of installing the vacuum insulation panel, The possibility of damage to the insulating panel is very high.

또, 시공된 이후에 충격을 받아 손상됨으로써 단열성능이 매우 나빠질 수 있는 문제점도 있다.In addition, there is a problem that the insulation performance may be deteriorated by being damaged by impact after the construction.

대한민국등록특허공보 제10-1243695호(2013.03.15.)에는 진공단열패널이 내장된 건축용 단열재가 개시되어 있다.Korean Patent Registration No. 10-1243695 (Mar. 19, 2013) discloses a thermal insulating material for building having a vacuum insulation panel incorporated therein.

상기 건축용 단열재는, 외부로부터의 충격을 흡수하도록 탄성을 갖는 재질로 이루어진 내장홈형성체와 내장홈차단체의 의해 진공단열패널이 감싸진 형태로 되어 있어 외부로부터의 충격에도 진공단열패널이 보호되고, 진공단열패널과 진공단열 패널 사이를 통한 열손실이 방지되므로 단열을 위한 시공과정이나 시공 후에 진공단열패널의 손상이 최소화되어 우수한 단열성능이 확보되는 장점이 있지만, 강도가 약한 단점이 있다.The construction heat insulating material has a shape in which a vacuum insulating panel is enclosed by a built-in groove forming body made of a material having elasticity so as to absorb impact from the outside and a built-in groove body so that the vacuum insulating panel is protected against external impact, Since the heat loss between the vacuum insulation panel and the vacuum insulation panel is prevented, the vacuum insulation panel is minimized in the construction process or after the installation for the insulation, and the excellent heat insulation performance is secured, but the strength is weak.

진공단열재는 심재 및 심재를 진공 포장하는 외피재로 구성되는데, 외피재로는 알루미늄 호일(foil)이 많이 사용된다.Vacuum insulation is composed of a cover material which vacuum-packs the core material and core material, and aluminum foil is often used as the cover material.

상기 진공단열재를 건축용 단열블록에 내장하는 경우에는, 강알칼리성이 강한 콘크리트 기반의 단열블록의 외피가 진공단열재의 외피재인 알루미늄 호일과 반응하여 알루미늄 호일이 부식되는 문제가 있다. 이로 인하여 진공단열재의 외피재인 알루미늄 호일에 핀홀(구멍)이 발생하여 진공이 파괴되는 현상이 나타난다.When the vacuum insulator is embedded in a building heat insulating block, there is a problem that the outer surface of a concrete-based heat insulating block having a strong alkaline property reacts with the aluminum foil, which is the sheath material of the vacuum insulation, to corrode the aluminum foil. As a result, pinholes (holes) are generated in the aluminum foil, which is the sheath material of the vacuum insulation, and the vacuum is broken.

대한민국공개특허공보 제10-2015-0089361호(2015.08.05.)에는 진공 단열재가 개시되어 있다. 상기 진공 단열재는 진공단열재의 외피재인 알루미늄 호일을 보호하는 보호층이 포함되어 있는데, 상기 보호층은 나일론 필름 또는 폴리에틸렌테레프탈레이트 필름을 사용한다. Korean Patent Laid-Open Publication No. 10-2015-0089361 (Aug. 5, 2015) discloses a vacuum insulation material. The vacuum insulation material includes a protective layer for protecting the aluminum foil, which is a sheath of the vacuum insulation material. The protective layer uses a nylon film or a polyethylene terephthalate film.

상기 보호층은 알루미늄 호일이 접힘 시 크랙이 발생되는 것을 방지하는 장점이 있지만, 알루미늄 호일의 부식을 방지하지 못하는 단점이 있다.The protective layer has an advantage of preventing cracks from occurring when the aluminum foil is folded, but it has a disadvantage that corrosion of the aluminum foil can not be prevented.
