Description
본 발명은 도료 분야에 관한 것으로서, 상세하게는 적외선 흡수층과 단열층의 적층 구조에 의한 건축물의 결로 방지 도료 및 이를 포함하는 단열구조에 관한 것이다.The present invention relates to the field of paints, and more particularly, to an anti-condensation paint for a building by a laminated structure of an infrared absorbing layer and a heat insulating layer and a heat insulating structure including the same.
동절기 공동 주택의 온도차에 의한 결로 발생은 국내의 주거환경 개선에서 고려할 매우 중요한 문제이며, 결로 발생에 따른 곰팡이 발생시 건강 문제 및 공동 주택의 가치 하락이 발생하고 아토피 등을 유발할 수 있어 다양한 결로 방지 도료가 개발 시판되고 있다.Condensation caused by the temperature difference in apartment buildings in winter is a very important issue to be considered in the improvement of domestic housing environment. When molds are generated due to condensation, health problems and decline in the value of apartment buildings may occur and cause atopy. Development is being marketed.
또한 최근 들어 단열에 관한 에너지 절감이 사회적 이슈이나 이에 관한 뚜렷한 대안이 부족한 실정이고, 일본 및 미국 등에서는 이를 해결하기 위한 방안으로 실리카 또는 무기질 비드를 이용한 열선 반사 단열 도료가 상용화되어 있다. 그러나 결로 방지와 단열은 메커니즘이 달라 실제 실내 결로 방지의 경우 추가적인 해결이 요구되고 있다.In recent years, the energy saving of insulation has been lacking in social issues and clear alternatives. In Japan and the United States, heat-reflective insulation paints using silica or inorganic beads have been commercialized to solve this problem. However, the prevention of dew condensation and the thermal insulation are different from each other.
이는 아래 표1과 같이 실내에서 발생하는 습기의 발생 요인과 발생량 등이 건축물의 표면의 온도와 밀접하게 관계됨으로써 결로가 발생하며 결로의 발생 요인인 벽체면의 온도 상승이 결로 방지를 위한 가장 중요한 요인이 되는 것이다.This is because as shown in Table 1 below, the cause and the amount of moisture generated in the room are closely related to the surface temperature of the building, so that condensation occurs and the temperature rise of the wall surface, which is a cause of condensation, .
실내 습기 발생 요인과 발생량Indoor moisture and factors
본 발명은 상기와 같은 문제점을 해결하기 위하여 건축물의 내부 공기층과 접촉하는 표면층에 열선 흡수층의 도료를 구성하고 그 하부에 세라믹 비드를 이용한 단열층을 구성한다. 이때 표면층은 실내의 열원으로부터 발생하는 난방 적외선을 흡수하게 되나 하부의 단열층이 열전도를 외부로 쉽게 배출하지 않음으로써 흡수한 열을 표면층에서 발생하는 결로의 건조에 이용하게 되는 구조를 구성하게 된다. 본 발명은 이러한 구조와 시공방법을 제공함으로써 실내의 결로를 방지하는 것을 목적으로 한다.In order to solve the above-described problems, the present invention forms a heat ray absorbing layer paint on a surface layer contacting with an inner air layer of a building, and a heat insulating layer using a ceramic bead below the paint layer. At this time, the surface layer absorbs the heating infrared rays generated from the heat source in the room, but the lower heat insulating layer does not easily discharge the heat conduction to the outside, and the absorbed heat is used to dry the condensation generated in the surface layer. The present invention aims to prevent indoor condensation by providing such a structure and a construction method.
상기 과제의 해결을 위하여, 본 발명은 도 1에 도시된 복합층 단열 도료를 구성하여야 한다. 표면층(열축척층, 적외선 흡수층)은 실내 난방이나 외부에서 들어오는 태양광, 실내등으로부터 쉽게 열을 흡수할 수 있는 도료로 구성되며 표면층 아래에 단열층을 두어야 한다. 단열층은 표면층이 흡수한 열이 외부로 빠져 나가는 것을 예방하여 흡수된 열이 발생하는 결로의 증발에 기여할 수 있게 도움을 주는 기능과 외부의 차갑거나 더운 환경으로부터 열의 입출을 제한할 수 있도록 구성되어야 효과적이다. 만일 단열층이 충분한 기능을 수행하지 못하게 될 경우 결로의 예방 기능은 약화될 수 있다. 그리고 이 단열층 외부에는 벽체 슬라브가 구비된다.In order to solve the above-mentioned problems, the present invention is required to constitute the composite layer insulation paint shown in Fig. The surface layer (thermal scale layer, infrared absorption layer) is composed of a paint that can easily absorb heat from indoor heating, sunlight coming from the outside, interior light, etc., and a thermal insulation layer should be placed below the surface layer. The insulation layer prevents the heat absorbed by the surface layer from escaping to the outside, thereby contributing to the evaporation of the condensation generated by the absorbed heat and effectively restricting the heat input and exhaust from the external cold or hot environment. to be. If the insulation layer fails to perform its full function, the preventive function of condensation can be weakened. A wall slab is provided outside the insulating layer.
적외선 흡수층과 단열층의 구성은 도료와 같은 형태로 구성될 수 있으나 어느 한쪽이나 양쪽을 필름의 형태로 구성하여 동일한 기능을 얻을 수 있다. 이러한 복층 구조는 한국과 같이 사계절이 뚜렷한 환경일수록 효과적이다.The constitution of the infrared absorbing layer and the heat insulating layer may be the same as that of the paint, but either or both of them may be constituted in the form of a film to obtain the same function. Such a multi - layered structure is more effective in an environment with four distinct seasons, as in Korea.
표면층(열축척층, 적외선 흡수층)의 두께는 특별히 규정치 않으나 너무 많은 열축적이 발생할 경우 인체가 벽체와 접촉할 때 상쾌하거나 따스한 느낌을 받을 없으며 가격이 상승하는 단점이 있다. 또한 780∼2500nm 영역의 열선의 흡수는 열선 흡수율이 적어도 20% 이상이 되어야한다. 만일 20% 보다 큰 경우 열 흡수가 크지 않아 발생한 결로를 증발시키기 어려우며 바람직한 열선의 흡수율은 40%이상이다. 적외선 흡수층에 이용될 수 있는 도료의 재질은 실리콘, 실리콘 변성 우레탄, 변성 폴리우레아, 아크릴등과 같이 접촉각이 낮은 도료가 바람직하다.Thickness of the surface layer (heat accumulation layer, infrared absorption layer) is not particularly specified, but if too much heat accumulation occurs, there is a drawback that the human body does not feel refreshing or warm when it comes into contact with the wall, and the price rises. Also, the absorption of heat rays in the region of 780 to 2500 nm should be at least 20% of the heat absorption rate. If it is larger than 20%, it is difficult to evaporate the generated condensation due to insufficient heat absorption, and the desirable absorption rate of heat rays is more than 40%. The material of the paint which can be used for the infrared absorbing layer is preferably a paint having a low contact angle such as silicone, silicone modified urethane, modified polyurea, acrylic, or the like.
반면 단열층의 경우 그 두께는 두꺼울수록 유리하나 너무 두꺼워 지는 경우 경제적이지 못하며 0.2mm 이내로 낮아지는 경우 단열효과가 나빠지는 단점이 있다. 그러나 열의 입출입에 중요한 척도는 열전도율이며 바람직한 열전도율은 0.1W/mk 이하이어야 한다. 바람직한 열전도율은 0.06W/mk이며 0.1W/mk보다 큰 경우 단열층의 열 손실에 의하여 표면층의 결로 증발 효과가 나빠질 수 있다. 바람직한 단열층의 두께는 0.2∼3mm이다. 다만 단열층의 도료는 중공비드를 이용한 것들이 바람직하며 도료의 밀도는 0.2∼1.0g/cm3인 것이어야 한다. 밀도가 0.2g/cm3 보다 작은 경우 비교적 쉽게 파괴되어 적합지 않으며 1.0g/cm3보다 큰 경우 열 전도율이 높아질 수 있다. 바람직한 밀도는 0.3∼0.8g/cm3이다.On the other hand, in the case of the insulating layer, the thicker the thickness is, the more economical it is if the thickness is too thick. If the thickness is lower than 0.2 mm, the adiabatic effect is deteriorated. However, an important measure for heat input and output is the thermal conductivity, and the preferred thermal conductivity is 0.1 W / mk or less. The preferable heat conductivity is 0.06 W / mk, and when it is larger than 0.1 W / mk, the heat loss of the heat insulating layer may deteriorate the evaporation effect of condensation on the surface layer. The preferable thickness of the heat insulating layer is 0.2 to 3 mm. However, it is preferable to use a hollow bead as the paint for the insulating layer, and the density of the paint should be 0.2 to 1.0 g / cm 3 . If the density is less than 0.2 g / cm 3 , it is relatively easily broken and is not suitable. If the density is higher than 1.0 g / cm 3 , the thermal conductivity may be increased. The preferred density is 0.3 to 0.8 g / cm < 3 & gt ;.
한편, 표면층 도료 100 중량부에 대하여, 착색제가 0.2~0.5 중량부 포함될 수 있다. 이 착색제는 트리페닐메탄 염료를 포함하고 4-[4-(N-에틸-p-설포늄벤질아미노)디페닐메틸렌]-[1-(N-에틸-N-p-설포늄벤질)-델타-2,5-사이클로헥사디엔이민]의 모노소듐 염을 포함할 수 있다. 이 착색제가 0.2 중량부 미만인 경우 착색 효과가 부족하고, 착색제가 0.5 중량부 초과인 경우 건조 속도가 저하하는 문제점이 있다.On the other hand, 0.2 to 0.5 parts by weight of a coloring agent may be added to 100 parts by weight of the surface layer paint. This colorant comprises a triphenylmethane dye and is selected from the group consisting of 4- [4- (N-ethyl-p-sulphonium benzylamino) diphenylmethylene] - [1- , 5-cyclohexadienimine]. ≪ / RTI > When the amount of the coloring agent is less than 0.2 parts by weight, the coloring effect is insufficient. When the amount of the coloring agent is more than 0.5 parts by weight, the drying speed is lowered.
표면층을 도포 전, 흡수 방지재(미도시)를 단열층 표면에 도포할 수 있다. 이 흡수방지재는, 아크릴계 모노머와 관능성 모노머 및 공중합 가능한 모노머를 유화 중합하여 제조된 수용성 아크릴중합체를 포함하는 것이 바람직하다.Before applying the surface layer, an absorption preventing material (not shown) may be applied to the surface of the heat insulating layer. The absorption preventing material preferably includes a water-soluble acrylic polymer produced by emulsion-polymerizing an acrylic monomer, a functional monomer and a copolymerizable monomer.
이 중 ① 아크릴계 모노머는 흡수 방지재를 구성하는 주성분이 되는 것으로, 그 사용량은, 180~220 중량부인 것이 바람직하며, 사용량이 180 중량부 보다 적으면 내수성이 및 내후성이 취약할 우려가 있고, 220중량부 이상 사용하는 경우는 유연성이 취약한 단점이 있게 된다.Among these, the (1) acrylic monomer is a main component constituting the anti-absorption material, and the amount thereof is preferably 180 to 220 parts by weight, and when the amount is less than 180 parts by weight, water resistance and weather resistance may be poor. If it is used in a weight portion or more, there is a disadvantage that flexibility is weak.
아크릴계 모노머로는 메틸아크릴레이트(Methylacrylate), 에틸아크릴레이트(Ethylacrylate), 부틸아크릴레이트(Butylacrylate), 2-에틸헥실아크릴레이트(2-Ethyhexylacrylate), 시클로헥실아크릴레이트, 메틸메타크릴레이트, 에틸메타크릴레이트, 부틸메타크릴레이트, 옥틸메타크릴레이트 등과 같은 아크릴산또는 메타크릴산 알킬에스테르류가 포함될 수 있다.Examples of the acrylic monomer include methylacrylate, ethyl acrylate, butylacrylate, 2-ethylhexylacrylate, cyclohexyl acrylate, methyl methacrylate, ethyl methacrylate, Acrylate or methacrylate alkyl esters such as methyl methacrylate, ethyl methacrylate, butyl methacrylate, octyl methacrylate and the like.
② 관능성 모노머는 아크릴계 모노머와 함께 유화 중합하는 것으로, 아크릴계 모노머와 같이 180~220 중량부인 것이 바람직하며, 사용량이 180중량부보다 적으면 내수성이나 내습윤 접착성이 불충분하게 되고, 220 중량부 이상 사용하는 경우는 분산성이 저하될 우려가 있다.(2) The functional monomer is emulsion-polymerized together with the acrylic monomer, and is preferably 180 to 220 parts by weight like the acrylic monomer. When the amount is less than 180 parts by weight, the water resistance and the wetting adhesion become insufficient, There is a possibility that the dispersibility may be lowered.
관능성 모노머는 글리시딜기 함유모노머를 포함할 수 있고, 글리시딜(메타)아크릴레이트(Glycidylmethacrylate), 글리시딜(메타)아릴에테르, 3,4-에폭시시클로헥실(메타)아크릴레이트 등을 들 수 있다. 이 중 시멘트 몰타르 조성물의 물 습윤시의 접착성을 위하여는 글리시딜메타아크릴레이트가 바람직하다.The functional monomer may include a glycidyl group-containing monomer, and may include glycidyl (meth) acrylate, glycidyl (meth) aryl ether, 3,4-epoxycyclohexyl (meth) . Among these, glycidyl methacrylate is preferable for adhesion of the cement mortar composition to water wetting.
③ 공중합 가능한 모노머로서는, 통상의 유화 중합에 사용 가능한 것이라면 특별한 제한은 없고, 예를 들면 아크릴산, 메타크릴산, 말레인산, 인타콘산, 크로톤산 등의 에틸렌성 불포화 카르본산; 에틸렌 등의 올레핀계 단량체; 스틸렌, α-메틸스틸렌, 비닐톨루엔 등의 스틸렌계 단량체 등을 포함할 수 있다.(3) The copolymerizable monomer is not particularly limited as long as it can be used in ordinary emulsion polymerization, and examples thereof include ethylenically unsaturated carboxylic acids such as acrylic acid, methacrylic acid, maleic acid, indaconic acid and crotonic acid; Olefinic monomers such as ethylene; Styrene-based monomers such as styrene,? -Methylstyrene, vinyltoluene, and the like.
공중합 가능한 모노머의 사용량은 30~50 중량부인 것이 바람직하며, 사용량이 30 중량부보다 적으면 내후성 및 경도가 취약해질 우려가 있고, 50 중량부 이상 사용하는 경우는 분산성이 취약하게 된다. The amount of the copolymerizable monomer to be used is preferably 30 to 50 parts by weight, and if the amount is less than 30 parts by weight, the weatherability and hardness may be weak. When the amount is more than 50 parts by weight, the dispersibility becomes poor.
본 발명은 기존의 단열 도료에 의한 결로 방지가 단순히 단열에 의한 결로 방지의 소극적 예방에 의하여 동절기 열관류율에 외기 접촉면의 온도하강 효과에 의한 결로 발생을 원천적으로 차단할 수 있는바 적외선 흡수층 + 단열층으로 구성함으로써 실내에서 발생하는 열원을 발생한 결로을 신속히 증발시키는 구조를 형성하여 결로에 의한 곰팡이등의 발생을 근본적으로 차단하는 효과가 있다. 또한 단열층을 구성함으로써 에너지 절감 효과를 부수적으로 얻을 수 있다.According to the present invention, it is possible to prevent condensation due to the temperature lowering effect of the outside air contact surface from the winter season by virtue of the passive prevention of condensation prevention by the existing heat insulating paint, The structure for rapidly evaporating the dew generated in the indoor heat source is formed, and the generation of mold and the like due to condensation is basically prevented. Further, by constructing a heat insulating layer, the energy saving effect can be obtained incidentally.

이하 본 발명의 실시예를 상세히 설명하면 다음과 같다.Hereinafter, embodiments of the present invention will be described in detail.
일반적으로 실시되는 아크릴계 유성도료 및 단열 도료(단열층)와 적외선 흡수+단열도료(표면층; 열축적층)를 각각 10x20cm의 알루미늄판에 부착시킨 후 표면의 건조속도를 측정하였다. 이때 사용된 단열도료는 열전도율이 0.09W/mk인 일본의 가이나사의 가이나(회색)를 1.0mm 도포하였으며 본 발명의 실시예에는 텅스텐계 적외선 흡수체가 포함시킨 모멘티브의 실리콘 레진 투명 도료를 0.1mm 도포하였다. 이후 시편을 물에 1분 동안 침지시키고 상대습도 60% 10℃의 온도에서 30W의 백열등 0.5mm 아래에서 건조시간을 측정하였다.(시험장치, 도2) 또한 도 3과 같은 장치를 이용하여 열원에 대한 단열 성능을 확인하였다. 그 결과는 표 2와 같이 단열 도료만 사용한 비교예1의 경우 표면이 젖은 후 완전히 건조되는데 걸린 건조시간은 480초였으나 본 발명의 실시예는 140초로 약 1/3으로 단축되어 결로가 발생하더라도 빠르게 건조됨으로써 곰팡이의 서식환경을 형성시키지 않을 것으로 판단된다. 그러나 비교예2의 일반 아크릴 페인트의 경우 단열 성능이 없어 후면의 온도가 높아짐으로써 발생열을 모두 손실함 동절기 벽체면은 더욱 냉각되어 이슬점이하로 낮아지게 되며 더욱 많은 결로가 발생할 수 있는 여건을 조성하는 것으로 확인되었다. The drying speed of the surface was measured after attaching an acrylic oil-based paint and a heat insulating paint (insulation layer) which are generally performed and an infrared absorbing + heat insulating paint (surface layer: heat accumulation layer) to an aluminum plate of 10x20 cm respectively. The heat insulating paint used herein was coated with 1.0 mm of cyan (gray) of a Japanese Guis screw having a thermal conductivity of 0.09 W / mk. In the embodiment of the present invention, the silicone resin clear coating material containing the tungsten- mm. Then, the specimen was immersed in water for 1 minute, and the drying time was measured at a relative humidity of 60% at a temperature of 10 ° C and a drying time of 0.5 mm below an incandescent lamp of 30 W. (Test Apparatus, FIG. 2) And the insulation performance for the test was confirmed. As a result, in the case of Comparative Example 1 using only the insulating paint as shown in Table 2, the drying time required for the surface to be completely dried after being wetted was 480 seconds, but the embodiment of the present invention was shortened to about 1/3 as 140 seconds, It is thought that it will not form the habitat environment of the mold by drying. However, in the case of the general acrylic paint of Comparative Example 2, since there is no insulation performance, all the generated heat is lost due to a rise in the temperature of the rear surface. The wall surface of the winter season is further cooled down to a level below the dew point, .
