Description

단열외장재{Adiabatic sheath}Insulation exterior material {Adiabatic sheath}

본 발명은 단열성 및 내충격성을 향상시킨 외장재에 관한 것이다.The present invention relates to an exterior material with improved insulation and impact resistance.

종래에 코어재가 외장재로 싸인 구조를 갖는 진공단열재가 제시된 바 있다. 상기 진공단열재에 있어서는 코어재의 주위가 진공상태로 유지되어 기체에 의한 열 전도율이 끝없이 제로에 가까워져 단열성능이 높아지게 되어 있다.Conventionally, a vacuum insulating material having a structure in which a core material is wrapped with an exterior material has been proposed. In the vacuum insulating material, the periphery of the core material is maintained in a vacuum state, and the thermal conductivity by the gas is endlessly close to zero, so that the heat insulating performance is increased.

이로 인해 진공단열재는 그 단열성능을 장기에 걸쳐서 유지하기 위해서 단열재 내부를 진공으로 계속해서 유지할 필요가 있다.For this reason, in order to maintain the thermal insulation performance over a long period of time, it is necessary for the vacuum insulating material to continuously maintain the inside of the thermal insulation material in a vacuum.

진공단열재 내부의 진공도를 유지하기 위해서 외장재의 가스 배리어성 및 내굴곡성의 향상은 진공단열재의 단열성능 유지를 생각한다는 점에서 대단히 중요하다.In order to maintain the degree of vacuum inside the vacuum insulation material, the improvement of the gas barrier properties and flex resistance of the exterior material is very important in view of maintaining the thermal insulation performance of the vacuum insulation material.

이러한 종래 기술의 예로 대한민국 특허공개 제10-2016-0094965호에서는 진공 단열재의 외장재이며, 플라스틱 기재를 포함하는 배리어 필름과, 상기 배리어 필름 상에 적층된 알루미늄 증착 에틸렌-비닐알코올 공중합체 필름과, 상기 알루미늄 증착 에틸렌-비닐알코올 공중합체 필름 상에 적층된 열 융착층을 구비하고, 상기 배리어 필름의 상기 플라스틱 기재 중 적어도 한쪽 면에는, 금속 또는 무기 산화물, 또는 금속 및 무기 산화물을 포함하는 혼합물로 형성된 증착 박막층과, 수용액 고분자와 (a) 1종 이상의 알콕시드 및 1종 이상의 알콕시드 가수분해물 중 적어도 한쪽 또는 (b) 염화주석 중 적어도 어느 하나를 포함하는 수용액, 또는 물과 알코올의 혼합 용액을 주제로 하는 코팅제를 포함하는 피막층이 순서대로 적층되어 있는 진공 단열재의 외장재를 제시하고 있다.As an example of such a prior art, in Korean Patent Publication No. 10-2016-0094965, a vacuum insulating material is an exterior material, a barrier film comprising a plastic substrate, an aluminum-deposited ethylene-vinyl alcohol copolymer film laminated on the barrier film, and the Aluminum deposition Deposition having a heat-sealable layer laminated on an ethylene-vinyl alcohol copolymer film, and formed of a metal or inorganic oxide or a mixture containing a metal and inorganic oxide on at least one side of the plastic substrate of the barrier film A thin film layer, an aqueous solution polymer and (a) at least one of at least one alkoxide and at least one alkoxide hydrolyzate, or (b) an aqueous solution comprising at least one of tin chloride, or a mixed solution of water and alcohol A coating material of a vacuum insulating material in which a coating layer containing a coating agent to be laminated is sequentially provided.

그런데 상기 기술의 경우 단열성은 확보될 수 있으나 외부의 충격 등에 대한 충격저항성은 보장할 수 없는 문제가 있다.However, in the case of the above technology, thermal insulation can be secured, but there is a problem in that impact resistance against external impact or the like cannot be guaranteed.

본 발명은 상기와 같은 문제를 해결하기 위하여 안출된 것으로서, 단열성이 확보되면서도 내충격성이 보장될 수 있는 외장재를 제공하고자 함이다.The present invention has been devised to solve the above problems, and is to provide an exterior material capable of ensuring impact resistance while ensuring insulation.

상기 목적을 이루기 위한 본 발명의 단열외장재는, 다공을 형성하는 복수의 단열층; 상기 단열층 사이에 게재되는 판형으로 복수의 간극이 형성되는 섬유층; 최외곽 단열층의 외주연에 도포되는 마감층;을 포함하는 것을 특징으로 한다.

하나의 예로 상기 섬유층은, 유리섬유의 직조에 의해 형성되되, 각각 메쉬를 형성하는 외피와 내피가 연결사에 의해 이격이 형성되도록 이중층의 구조로 직조됨을 특징으로 한다.

도 3은 섬유층의 일 실시예를 나타내는 측단면도이다.1 is a side cross-sectional view showing a basic example of the present invention,
FIG. 2 is a cutaway perspective view of the example shown in FIG. 1,
3 is a side cross-sectional view showing an embodiment of a fiber layer.

이하 본 발명의 실시 예들을 첨부되는 도면을 통해 보다 상세히 설명하도록 한다.Hereinafter, embodiments of the present invention will be described in more detail through the accompanying drawings.

본 발명의 단열외장재(1)는 도 1 및 도 2에서 보는 바와 같이 다공을 형성하는 복수의 단열층(2); 상기 단열층(2) 사이에 게재되는 판형으로 복수의 간극이 형성되는 섬유층(3); 최외곽 단열층(2)의 외주연에 도포되는 마감층(4);을 포함하는 것을 특징으로 한다.Insulating exterior material (1) of the present invention includes a plurality of insulating layers (2) forming a porous as shown in Figures 1 and 2; A fiber layer 3 in which a plurality of gaps are formed in a plate shape interposed between the heat insulating layers 2; It characterized in that it comprises a; finishing layer (4) applied to the outer periphery of the outermost insulating layer (2).

상기 단열층(2)은 다공을 형성하는 재질로서 바람직하게는 탄성이 있는 재질로 구성하여 충격에 대한 저항성을 향상시키도록 하는 것이 타당하다. 일 예로 상기 단열층(2)은 스티로폴이 사용될 수 있다.The insulating layer 2 is a material for forming a porous body, and is preferably made of an elastic material to improve resistance to impact. For example, a styropole may be used as the heat insulating layer 2.

상기 섬유층(3)은 상기 단열층(2) 사이에 게재되는 구성으로 도면에 도시된 바는 없으나 프라이머에 의해 부착이 되도록 하는 것으로 단열층(2) 사이에 상기 섬유층(3)이 게재됨에 의해 단열층(2) 간의 부착력을 강화시킬 수 있으며 섬유층(3)에 의해 단열층(2)의 강도가 보강되도록 하는 것이다.The fiber layer (3) is a configuration that is placed between the heat insulating layer (2), but not shown in the drawing, but to be attached by a primer, so that the fiber layer (3) is placed between the heat insulating layer (2), so that the heat insulating layer (2 ) It is possible to strengthen the adhesion between the liver and to reinforce the strength of the heat insulating layer 2 by the fiber layer 3.

이러한 섬유층(3)은 복수의 섬유사가 직조 등에 의해 연결되면서 상,하로 적층이 되도록 하여 섬유사 사이에 복수의 간극이 형성되도록 하는 것이다. 이렇게 구성됨에 의해 프라이머가 간극으로 함침되면서 상,하로 적층되는 단열층(2)과의 부착력을 향상시키고 강도를 보강하게 되는 것이다.The fibrous layer 3 is such that a plurality of fiber yarns are connected by weaving or the like to be stacked up and down to form a plurality of gaps between the fiber yarns. By this configuration, the primer is impregnated with a gap, thereby improving adhesion with the heat insulating layer 2 stacked up and down and reinforcing strength.

한편 도 3에서는 상기 섬유층(3)의 일 실시예가 도시되고 있다.Meanwhile, in FIG. 3, an embodiment of the fiber layer 3 is illustrated.

본 실시예의 섬유층(3)은 도 3에서 보는 바와 같이 유리섬유(S)의 직조에 의해 형성되되, 각각 메쉬를 형성하는 외피(31)와 내피(32)가 연결사(33)에 의해 이격이 형성되도록 이중층의 구조로 직조됨을 특징으로 한다.The fiber layer 3 of this embodiment is formed by weaving of the glass fibers S, as shown in FIG. 3, and the outer shell 31 and the inner shell 32 forming a mesh are separated by a connecting yarn 33, respectively. It is characterized in that it is woven into a double layer structure to be formed.

이와 같이 유리섬유(S)의 직조에 의해 이중층의 구조로 형성되도록 함으로써 프라이머와 부착력을 견고히 하고 연결사(33)의 구조에 의해 외피(31)와 내피(32)에 탄성이 부과됨으로써 충격저항성을 향상시킬 수 있게 되는 것이다. 즉 이중층의 구조에 의해 외부충격에 대한 저항성을 향상시킬 수 있게 되는 것이며 프라이머와 유리섬유 간에 부착력을 견고히 가져갈 수 있게 되는 것이다.Thus, by forming the structure of the double layer by weaving of the glass fiber (S) to secure the primer and adhesion, elasticity is imposed on the outer shell 31 and the inner shell 32 by the structure of the connecting yarn 33, thereby improving the impact resistance. It can be improved. In other words, it is possible to improve the resistance to external shock by the structure of the double layer, and it is possible to firmly bring the adhesion between the primer and the glass fiber.

한편 프라이머가 경화하는 과정에서 수축을 동반하게 되는데 이러한 수축에 의해 섬유층(3)도 수축에 의해 균열을 유발할 수 있으며 섬유층(3)과 단열층(2) 간 들뜸이 발생될 수 있다.On the other hand, the primer is accompanied by shrinkage in the process of curing. Due to this shrinkage, the fibrous layer 3 may also cause cracking due to shrinkage, and excitation between the fiber layer 3 and the heat insulating layer 2 may occur.

이에 본 발명에서는 도 3에서 보는 바와 같이 상기 섬유층(3)에 형성되는 간극에는 팽창질석 분말(34)이 게재되도록 하는데 이는 섬유층(3)에 팽창질석 분말(34)을 살포하여 섬유층(3)에 형성된 간극에 팽창질석 분말(34)이 게재되도록 하는 것이다. 이와 같이 구성되어 단열층(2) 사이에서 프라이머가 함침된 상태로 섬유층(3)이 게재되면 프라이머와 팽창질석 분말이 반응하여 팽창질석 분말이 팽창됨으로써 섬유층(3)의 수축을 보상하게 되는 것이다. 즉 섬유층(3)에 발생될 수 있는 균열 및 섬유층(3)과 단열층(2) 사이에 들뜸의 문제를 해결하게 되는 것이다.Accordingly, in the present invention, as shown in FIG. 3, the expanded vermiculite powder 34 is placed in the gap formed in the fiber layer 3, which is applied to the fiber layer 3 by spraying the expanded vermiculite powder 34 to the fiber layer 3 The expanded vermiculite powder 34 is placed in the formed gap. When the fiber layer 3 is placed in such a state that the primer is impregnated between the heat insulating layers 2, the primer and the expanded vermiculite powder react to expand the expanded vermiculite powder, thereby compensating for shrinkage of the fiber layer 3. That is, to solve the problem of floating between the fibrous layer 3 and the heat insulating layer 2 and cracks that may occur in the fiber layer 3.

여기에 더하여 상기 팽창질석은 다공에 탄산수소칼륨 용액이 함침된 상태에서 코팅층이 형성된 것이 더욱 바람직하다.In addition to this, the expanded vermiculite is more preferably formed with a coating layer impregnated with potassium hydrogen carbonate solution in the pores.

상기 탄산수소칼륨 용액은 프라이머가 경화되는 과정에서 발생되는 열을 흡수토록 하며 프라이머 등에 포함되어 있는 유기물질을 흡착하는 기능을 한다. 이와 같이 팽창질석에 함침된 탄산수소칼륨 용액이 프라이머로부터 열을 흡수함으로써 수화열에 의한 균열 즉 섬유층의 수축을 제어토록 하는 것이다. 앞서 설명한 바와 같이 팽창질석은 물리적으로 균열을 제어하는 것이고, 탄산수소칼륨 용액은 수화열을 흡수하여 균열을 제어토록 하는 것이다. 이에 더하여 단열층(2)과 섬유층(3)의 경계면에 유기물이 존재하는 경우 유기물의 부식에 의해 경계면에서 들뜸이 발생되고 이러한 부식은 균열 등 내구성 저하요인으로서 작용을 하는데 탄산수소칼륨 용액은 유기물을 흡착함으로써 이러한 문제를 해결토록 하는 것이다.The potassium hydrogen carbonate solution absorbs heat generated in the process of curing the primer and adsorbs organic substances contained in the primer. In this way, the potassium hydrogen carbonate solution impregnated with the expanded vermiculite absorbs heat from the primer to control the crack caused by heat of hydration, that is, the contraction of the fiber layer. As described above, the expanded vermiculite physically controls cracking, and the potassium hydrogen carbonate solution absorbs heat of hydration to control cracking. In addition, when an organic substance is present at the interface between the heat insulating layer 2 and the fiber layer 3, excitation occurs at the interface due to corrosion of the organic substance, and such corrosion acts as a decrease factor in durability such as cracking. Potassium hydrogen carbonate solution adsorbs the organic substance. By doing so, it is to solve these problems.

상기 코팅층은 다양한 재질의 수지로서 코팅층이 형성되도록 할 수 있는 바, 이는 보관과정 등에서 기 반응이 이루어지는 것을 방지토록 하는 것이다.The coating layer is a resin of various materials that allows the coating layer to be formed, which is to prevent the pre-reaction during storage.

상기 마감층(4)은 최외곽 단열층(2)의 외주연에 도포되는 구성으로 그 재질을 한정하지 않으나 내마모성이 있어야 하고, 안료가 선택적으로 배합되어 색상이 선택적으로 구현될 수 있으며, 이산화티탄 등이 포함되어 유기물의 분해를 통해 이물질의 침적을 방지토록 할 수 있다.The finishing layer 4 is a composition applied to the outer periphery of the outermost insulating layer 2, but does not limit its material, but must have abrasion resistance, and pigments can be selectively blended to realize colors selectively, titanium dioxide, etc. This is included to prevent deposition of foreign matter through decomposition of organic matter.
