Description

아스팔트 슁글 지붕의 단열 차열 방수 도료조성물 및 이를 이용한 단열 차열 방수공법{Asphalt shingle-roof heat insulation waterproofing paint composition and thermal insulation waterproofing method using the same}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an asphalt shingle roof construction, an asphalt shingle roof construction, and a thermal insulation waterproofing method using the asphalt shingle roof,

본 발명은 아스팔트 슁글 지붕의 단열 차열 방수 도료조성물 및 이를 이용한 단열 차열 방수공법에 관한 것으로, 보다 상세하게는 하도제를 사용하지 않고도 수용성의 저독성, 저공해 친환경 방수처리가 가능하고, 이와 함께 내후성과, 내구성 및 내수성이 우수하며, 열차단, 열반사 성능 및 낮은 열전도율을 가지고 있어 냉난방 에너지를 절감하고, 자외선 차단 기능도 포함하고 있어 방수 사용수명이 연장되며, 시공이 간편하고 작업시간이 단축되어 공사비도 줄일 수 있도록 개선된 아스팔트 슁글 지붕의 단열 차열 방수 도료조성물 및 이를 이용한 단열 차열 방수공법에 관한 것이다.The present invention relates to a waterproof thermal insulation coating composition for asphalt shingle roofs, and to an adiabatic thermal insulation waterproofing method using the same. More specifically, the present invention relates to a waterproof thermal insulation waterproofing coating composition for asphalt shingles, It has excellent durability and water resistance. It has heat shield, heat reflection performance and low thermal conductivity to save cooling and heating energy. It also has ultraviolet shielding function to extend waterproof service life, and it is easy to construct, The present invention relates to a waterproof thermal insulation coating composition for asphalt shingles, and to an insulation thermal insulation waterproofing method using the same.

건축물의 지붕 재료로 콘크리트, 금속, 아스팔트 슁글, 기와, 슬레이트 등 매우 다양한 재료를 사용한다. 이런 재료들의 수명 및 방수 성능을 확보하여 건축물을 장기적인 내구성을 확보하기 위해서는 열과 습기를 제어할 수 있어야 한다.The roof material of the building uses a wide variety of materials such as concrete, metal, asphalt shingle, tile, and slate. To ensure long life and waterproof performance of these materials and to ensure long-term durability of buildings, heat and moisture must be controlled.

특히, 아스팔트 슁글 지붕의 경우 태양열의 노출에 의한 방수성능의 저하는 방수문제 및 건축물의 내구성을 확보하기 위해 먼저 해결하여 할 시급한 문제이다.Particularly, in the case of asphalt shingle roof, degradation of waterproof performance due to exposure to solar heat is an urgent problem to be solved first to secure waterproofing and durability of buildings.

그런데, 기술개발의 진보와 시공기간, 시공비용 등의 문제로 보수에 필요한 도막의 두께가 점점 얇아지고 있는 추세이다.However, due to advances in technology development, construction time, construction costs, and the like, the thickness of the coating film required for maintenance is gradually becoming thinner.

하지만, 아스팔트 슁글 지붕에 두께가 두꺼운 도막형 방수제가 아닌 단순히 차열, 단열 기능이 있는 얇은 두께의 박막형 도료(상도만 처리)를 시공할 경우, 단기간에는 단열이나 차열 효과를 얻을 수 있지만 방수가 잘 되지 않고, 시간이 지나면서 태양열 흡수에 따른 열화 가속, 오염(매연, 미세먼지, 황사 등)에 의해 내구성, 내후성, 내수성, 내마모성이 급격히 저하되면서 혹서와 혹한이 교대되면서 비, 눈 등에 의한 기온변화에 의해 도막이 쉽게 들떠 오르고 크랙이 발생되는 하자가 빈번하게 발생하고 있다.However, when the thin film type coating (Thodomain treatment), which is not a thick film-like waterproofing agent on the roof of the asphalt shingle, but merely has the heat shielding function and the thermal insulation function, it is possible to obtain the effect of heat insulation or heat shielding in a short period of time. As time passes, durability, weatherability, water resistance and abrasion resistance are rapidly decreased due to acceleration of deterioration due to solar absorption, pollution (soot, fine dust, yellow dust, etc.) The coating film is easily excited and cracks are generated frequently.

여기에서, 최근의 지붕 보수 관련 도료의 추세는 에너지 절감과 연관되어 차열의 개념이 도입되었는데, 차열은 단열과는 구분되는 개념으로 단열이 열차단의 개념이라면 차열은 열반사의 개념이라고 이해하면 된다.Here, the recent tendency of paint related to roof repair related to energy conservation is introduced with the concept of heat insulation. If heat insulation is a concept of heat insulation, it is understood that heat insulation is a concept of heat reflection.

통상, 금속재료의 표면온도는 하절기에 60~80℃정도로 상승하나 차열 도료로 도장된 지붕은 태양광선을 반사하기 때문에 금속 표면온도를 40℃ 정도로 낮추어 주는 것으로 알려져 있다.Generally, the surface temperature of metal materials is raised to 60 to 80 ° C in the summer season, but the roof painted with the heat paint is known to lower the metal surface temperature to about 40 ° C because it reflects sunlight.

또한, 아스팔트 슁글 지붕에 대한 방수공법에 있어서도 기본적으로 하도제, 중도제, 상도제를 모두 처리하고 있기 때문에 비용과 시간이 많이 걸리는 단점이 있다. 반면에, 도막 두께를 박막형으로 한 경우에는 상술한 바와 같은 문제가 있는 것으로 설명하였다.Also, in the waterproofing method for the asphalt shingle roof, since the undercoating agent, the intermediate coating agent and the topcoating agent are all treated basically, it takes a lot of cost and time. On the other hand, in the case where the film thickness is made thin, the above-mentioned problems have been described.

일반적으로, 아스팔트 슁글 지붕의 방수 단열을 위한 방수공법은 하도제, 중도제, 상도제를 모두 도포하여 도막을 만들고 있으나 본 발명은 하도제를 생략한 채 중도제와 상도제만으로 구성하여 기존 방수공법을 완전히 대체하면서 동시에 단열과 차열 기능까지 구현하도록 구성된 것이다.Generally, the waterproofing method for waterproof insulation of an asphalt shingle roof is applied by applying all the undercoating agent, the modifier agent and the topcoating agent. However, the present invention does not include the undercoating agent, And at the same time, the heat insulation and the heat shielding function are realized.

때문에, 상도제 단독으로만 구성했을 경우의 종래 문제를 해결하면서 도막 두께도 낮추면서 시공기간도 단축시키고 시공비용도 줄이며, 단열과 차열의 개념이 모두 포함됨으로 인해 냉난방(여름철 냉방 최고 40%/ 겨울철 난방 최고 20%)의 에너지 비용을 획기적으로 절감할수 있고, 자외선을 최고 89% 차단하여 체감온도 상승억제와 방수제의 수명을 연장할 수 있다.Therefore, by solving the conventional problem of solely constructing the top coat alone, it is possible to reduce the thickness of the coating film, shorten the construction period, reduce the construction cost, and include both the heat insulation and the heat insulation. Saving up to 20% of energy), and it cuts ultraviolet rays up to 89%, which can suppress temperature rise and extend the life of waterproofing agent.

보다 구체적으로, 본 발명에 따른 아스팔트 슁글 지붕의 단열 차열 방수공법은 도 1의 예시와 같이, 아스팔트 슁글 지붕 표면인 피도포면(100), 단열 차열 방수 기능을 갖는 중도층(200), 단열 차열 방수 기능을 갖는 상도층(300)이 순차로 적층 형성되는 형태로 도포 시공된다.More specifically, the asphalt shingle roof waterproofing method according to the present invention is an asphalt shroud roof waterproofing method in which a surface 100 to be an asphalt shingle roof surface, a middle layer 200 having an adiabatic heat shielding waterproof function, And the upper layer 300 having the function of forming the upper layer 300 are sequentially laminated.

이때, 상기 상도층(300)이 본 발명에서 핵심적인 특징으로 제시하는 구성이며, 이를 조성하는 도료조성물에 대해서는 상세히 후술한다.At this time, the top coat layer 300 is a key feature of the present invention, and a coating composition for forming the top coat layer 300 will be described later in detail.

이러한 단열차열 방수구조를 갖도록 시공하는 아스팔트 슁글 지붕의 단열 차열 방수공법은 아스팔트 슁글 지붕에 적용되며, 지붕 표면이 피도포면(100)이 된다.The asphalt shingle roof waterproofing method is applied to the asphalt shingle roof, and the roof surface is the surface 100 to be coated.

그리고, 본 발명은 지붕 세정단계, 바탕 처리단계, 중도제 도포단계 및 상도제 도포단계로 이루어진다.In addition, the present invention comprises a roof cleaning step, a background treatment step, a middle coat application step, and a top coat application step.

이때, 상기 지붕 세정단계는 아스팔트 슁글 지붕의 표면에 잔류된 먼지, 유분, 낙엽 등의 이물질을 깨끗하게 청소하여 제거하는 단계로서, 반드시 송풍기를 사용하여 송풍하면서 빗자루로 쓸어내는 방식으로 제거해야 한다.At this time, the roof cleaning step is a step of cleanly removing foreign matters such as dust, oil, and leaves left on the surface of the asphalt shingle roof, and must be removed by blowing with a blower while sweeping with a broom.

깨끗하게 세척하기 위해 물청소를 하거나 고압세척기를 이용하게 되면 균열이 더 커질 뿐만 아니라, 균열로 물이 스며든 상태가 되므로 도막 형성 후 균열이 완전히 보수되지 못하고 잔류된 물에 의해 도막 들뜸이 발생하기 때문이다.If you clean the water to clean it or use a high pressure washer, it will not only make the cracks bigger but also cause the water to seep into the cracks, so that the cracks can not be completely repaired after the film is formed, to be.

이렇게 하여, 지붕 세정단계가 완료되면, 바탕 처리단계가 수행된다.Thus, when the roof cleaning step is completed, a background processing step is performed.

상기 바탕 처리단계는 아스팔트 슁글 지붕의 들뜬 부위, 균열 부위, 가장자리를 우레탄 실란트로 보수하고, 아스팔트 슁글 상태가 낡거나 파손된 부분은 부분적으로 교체하는 단계이다.The base treatment step is a step of repairing the asphalt shingle roof, the cracked part and the edge of the asphalt shingle roof with a urethane sealant, and partially replacing the old or damaged part of the asphalt shingle.

이와 같이 바탕 처리단계까지 마무리하게 되면 중도제를 도포할 수 있는 상태가 된다.When the base processing step is completed, the intermediate agent can be applied.

상기 중도제 도포단계는 교반 완료된 중도제를 로울러로 1회 도장하고, 완전히 건조된 후에 다시 한번 2회 도장하는 방식으로 이루어진다.In the intermediate application step, the stirring agent is coated once with a roller, and completely dried and then coated twice.

이때, 상기 중도제는 고탄성 에멀젼수지 40-52중량%, 이산화티탄 10-18중량%, 탄산칼슘 12-20중량%, 마그네슘 2-4중량%, 황산에스테르 0.5-3중량%, 유기인산염 0.5-2중량%, 메틸파라벤 0.5-2중량%, 에톡시레이티드 알코올 1-3중량%, 화이트카본 1-5중량%, 알루미늄 실리게이트 미세 중공체분말 10-15중량% 및 나머지 물로 조성된다.At this time, the intermediate agent is a mixture of 40-52 wt% of high elasticity emulsion resin, 10-18 wt% of titanium dioxide, 12-20 wt% of calcium carbonate, 2-4 wt% of magnesium, 0.5-3 wt% of sulfuric acid ester, 2% by weight of methylparaben, 0.5-2% by weight of methylparaben, 1-3% by weight of ethoxylated alcohol, 1-5% by weight of white carbon, 10-15% by weight of aluminum silicate microcellular powder and the balance of water.

여기에서, 상기 고탄성 에멀젼수지는 탄성력을 부여하기 위해 첨가되는 것으로, 아크릴 공중합체 에멀젼수지와 폴리우레탄 에멀젼수지를 1:1의 중량비로 혼합한 혼합물을 사용한다.Here, the high-elasticity emulsion resin is added to impart an elastic force, and a mixture obtained by mixing an acrylic copolymer emulsion resin and a polyurethane emulsion resin at a weight ratio of 1: 1 is used.

특히, 아크릴 공중합체 에멀젼수지는 피도포면에 피막을 형성하면서 공극을 메워 무밀성을 증대시키고, 상기 폴리우레탄 에멀젼수지는 접착력을 증대시켜 부착강도를 높임으로써 견고한 고정성을 유지하면서 탄성있는 도막특성을 갖게 한다.Particularly, the acrylic copolymer emulsion resin increases the non-tightness by forming a film on the surface to be coated while increasing the non-tightness, and the polyurethane emulsion resin increases the adhesion strength to increase the adhesion strength, thereby improving the elastic film property .

이를 위해, 상기 조성비율로 첨가되어야 하는데, 40중량% 미만으로 첨가되면 탄성효과 및 수밀성이 떨어지고, 52중량%를 초과하면 압축강도 및 바인딩성이 크게 증가되어 도포성, 혼합성이 떨어지므로 상기 범위로 한정하여야 한다.If it is added in an amount of less than 40% by weight, the elastic effect and the water tightness become poor. When the content is more than 52% by weight, compressive strength and binding property are greatly increased, .

또한, 상기 이산화티탄은 표백 및 색상을 밝게 하여 백색도 유지, 은폐율 향상을 위해 첨가된다.Further, the titanium dioxide is added to brighten whiteness and hue to maintain whiteness and to improve concealment rate.

본 발명에서 구분없이 분말형태로 배합되며, 10중량% 미만으로 첨가되면 표백 및 색상 구현이 어렵고, 18중량%를 초과하면 과표백이 일어나 색상 불량 및 불균형을 유발하므로 상기 범위로 한정하여 배합하여야 한다.In case of less than 10% by weight, it is difficult to realize bleaching and coloring. When it exceeds 18% by weight, overprinting occurs and color deficiency and unbalance are caused.

아울러, 상기 탄산칼슘은 피막 형성을 증대시키기 위해 첨가되며 수용성이기 때문에 균열은 물론 보수가 불균일한 부분 등에 침투하여 방수성을 더욱 극대화시킨다.In addition, since the calcium carbonate is added to increase the film formation and is water-soluble, it infiltrates cracks and uneven portions of maintenance, thereby further maximizing the water resistance.

다만, 혼합시 희석에 따른 점도 저하를 막기 위해 상기와 같은 12-20중량%의 범주내에서 첨가되어야 한다.However, it should be added in the range of 12 to 20% by weight in order to prevent the viscosity decrease due to dilution during mixing.

아울러, 상기 마그네슘은 점도를 조절하고 침전을 방지하기 위한 것으로 2-4중량% 첨가된다.In addition, the magnesium is added in an amount of 2-4 wt% for controlling viscosity and preventing precipitation.

또한, 상기 황산에스테르는 도료의 제조공정에서 첨가물의 분산을 쉽게 하기 위해 0.5-3중량% 첨가된다.The sulfuric acid ester is added in an amount of 0.5-3% by weight in order to facilitate the dispersion of the additive in the process of manufacturing the paint.

뿐만 아니라, 상기 유기인산염은 고속교반중 기포발생을 억제함은 물론 도포면을 평활하게 유지하기 위해 첨가된다.In addition, the organic phosphate is added in order to suppress the generation of bubbles during high-speed stirring and to keep the application surface smooth.

그리고, 상기 메틸파라벤은 부패를 방지하거나 억제하기 위해 첨가된다.And, the methylparaben is added to prevent or suppress the decay.

또한, 상기 에톡시레이티드 알코올은 분산성을 증대시키기 위해 첨가된다.In addition, the ethoxylated alcohol is added to increase the dispersibility.

아울러, 상기 화이트카본은 칙소성을 부여하기 위한 칙소화제(Thixotroping Agents)로서, 도막 표면 변형이나 변성을 최소화시키기 위해 첨가되며, 과량 첨가시에는 점도가 높아지고, 소량 첨가시에는 기능이 유명무실해지기 때문에 상기 범위로 첨가되어야 한다.In addition, the white carbon is added to minimize the surface deformation and denaturation of the coating film, and the viscosity is increased when the amount is excessively added, and the function is not known when the amount is small Should be added in the above range.

또한, 상기 알루미늄 실리게이트 미세 중공체분말(통상 '인슐래드'라 칭하며, 미크론 크기임)은 폐쇄 공기층의 열차폐 열반사와 열저항을 갖는 유해 중금속은 물론 휘발성 유기화합물및 독성이 전혀 없는 환경 친화적인 소재이다.In addition, the above-mentioned aluminum silicate micro hollow powder (usually called 'insulin', micron size) is used as a material for the heat treatment of thermal barrier heat of the closed air layer and harmful heavy metals having thermal resistance, as well as volatile organic compounds and environment- to be.

상기 알루미늄 실리게이트 미세 중공체분말을 10중량% 미만으로 첨가하며 단열성 및 결로방지성이 떨어지고, 15중량%를 초과하여 첨가하면 단열성이 증가하는 장점은 있으나 혼합성과 윤활성이 떨어지므로 상기 범위로 한정되어야 한다.The aluminum silicate micro hollow powder is added in an amount of less than 10% by weight and the heat insulating property and the dew condensation preventing property are poor. When it is added in an amount of more than 15% by weight, the heat insulating property is increased. However, do.

이에 더하여, 본 발명은 이와 같은 중도제 조성물을 구성할 때, 기능성 물질을 더 첨가함으로써 기능 증대효과를 더 얻을 수 있는데, 이를 테면 중도제 조성물 100중량부에 대해 프로스타글란딘(prostaglandin) 7.5중량부와, 솔루빌라이저(Solubilizer) 12.5중량부와, 유산반토 3.5중량부를 더 첨가할 수 있다.In addition, when the intermediate composition of the present invention is formed, a functional enhancing effect can be further obtained by further adding a functional material.
