본 발명은 방수성과 고내구성을 가지는 복합시트를 이용한 방수시공방법으로서, 보다 상세하게는 경화된 아스팔트프라이머 상부로부터 Styrene-Butadiene-Styrene 고분자합성개질아스팔트방수층, Ethylene-vinyl acetate copolymer 코팅층, Polypropylene 직물층, 고밀도Polypropylene 필름층 및 Polypropylene 부직포층 순서로 부착되어 이루어진 다층구조를 가지는 복합시트를 이용함으로써, 복합시트와 다른 층들과의 결합력 증가시키며, 기존의 방수시공과정에서 발생할 수 있는 수분, 유기용제 및 기타 방수용화합물의 침투와 콘크리트층 또는 아스팔트층과 결합에 의한 변형을 방지하여 방수하자 발생을 억제하고, 강도가 우수한 복합시트를 이용함으로써 외부의 온도나 습도 등의 변화, 또는 외부의 충격이 의하여 2차 균열의 발생을 억제하며 콘크리트 등에 발생한 1차 균열의 확산을 방지할 수 있어 오랜 수명을 가지는 방수성과 고내구성을 가지는 복합시트를 이용한 방수시공방법에 관한 것이다. The present invention is a waterproof construction method using a composite sheet having waterproof and high durability, and more specifically, Styrene-Butadiene-Styrene polymer-synthetic modified asphalt waterproofing layer, Ethylene-vinyl acetate copolymer coating layer, Polypropylene fabric layer, By using a composite sheet having a multi-layer structure formed by attaching a high density polypropylene film layer and a polypropylene nonwoven layer in order, it increases the bonding strength between the composite sheet and other layers, and water, organic solvent, and other waterproofing that may occur in the existing waterproof construction process. It prevents the penetration of compound and deformation by combining with concrete layer or asphalt layer to prevent the occurrence of waterproof defects, and by using composite sheet with high strength, it is secondary crack by change of external temperature or humidity or external impact.

종래의 집합건물구조물에서 옥상 등의 콘크리트 바닥 마감처리방법은 콘크리트 바닥의 표면에 아무런 마감처리를 하지 않은 노출 상태로 유지시키거나, 표면을 폴리싱하여 갈아내고 매끄럽게 만든 다음 일정의 코팅제를 도포한 후 재차 폴리싱하는 방법을 이용하였다. 특히, 바닥에 일정의 기능성 코팅재를 도포하여 옥상 등의 콘크리트 바닥의 표면을 강화시키기 위한 방수시공방법은 방수성, 내화학성 및 내마모성 등 기능을 갖춘 표면코팅제의 발달로 다양한 시공방법이 제시되고 있다. 그러나 바닥에 일정의 기능성 코팅재를 도포하여 옥상 등 콘크리트 바닥의 표면을 강화시키기 위한 방수시공방법은 그 방수성, 내화학성, 내마모성 및 내구성 등 기능이 미흡한 측면이 있어, 보완책으로 방수라이닝 시공방법이 제안되었다. In the conventional aggregate structure, the concrete floor finishing method such as the rooftop is maintained in the exposed state without any finishing on the surface of the concrete floor, or the surface is polished and polished, smoothed, and then coated with a certain coating agent again. Polishing method was used. In particular, the waterproof construction method for reinforcing the surface of the concrete floor such as the roof by applying a certain functional coating material on the floor has been proposed a variety of construction methods by the development of a surface coating agent having a function such as waterproof, chemical resistance and wear resistance. However, the waterproof construction method for reinforcing the surface of concrete floors such as rooftops by applying a certain functional coating material on the floor has insufficient functions such as waterproofness, chemical resistance, abrasion resistance, and durability, and waterproof lining construction method has been proposed as a complementary measure. .

종래의 방수라이닝 시공방법을 이용하는 집합건물구조물의 옥상방수는 대부분 비노출 시트를 이용한 옥상방수방법을 이용하였으며, 비노출 시트를 이용한 옥상방수방법은 준공 후 5년 이상이 지나면 몰탈층의 균열로 인해 누수가 발생되기 시작하는 문제가 있었고, 이러한 누수에 대한 보수방법으로 대부분이 폴리우레탄노출방수를 선택하여 추가적인 보수 공사를 진행하고, 그 외에 PVC노출시트방수, 무기질도막방수 등이 누수에 대한 보수방법으로 선택되고 있는 실정이다. 그러나 상기 누수에 대한 종래의 보수방법은 모두 노출방수공법으로서 자외선에 의해 노화가 진행되어 내구 연한이 3~7년 정도로 내구성이 떨어지는 문제가 있고, 짧은 시간 안에 다시 재시공해야 하므로 경제적인 측면에서 어려움이 발생할 위험이 크다. 특히 폴리우레탄노출방수는 시공 후 3년이 지나면 바닥상태에 따라 기포발생, 균열, 노화 등의 문제점들이 나타나기 시작하며 5~7년 사이에는 재시공을 해야하는 상황이 다시 발생한다. 이러한 문제들은 폴리우레탄재료가 가지고 있는 근본적인 문제 즉, 수분과의 반응성이 높은 문제, 경도가 60(Shore A) 이하인 경우에 자외선에 의한 노화가 쉽게 발생하는 문제(폴리우레탄재료의 경도가 높을수록 자외선에 의한 노화에는 강함), 폴리우레탄 주제와 경화제의 배합불량으로 인한 방수층의 불량의 문제 등의 요인에 의해 발생된다. 또한 집합건물구조물 옥상방수의 보수방법 중 PVC노출 시트방수는 층간접착부위에서 시간이 경과함에 따라 접착불량이 발생되어 누수의 원인이 되는 문제가 발생할 수 있으며, 무기질도막방수도 도막방수재의 탄성이 약하므로 균열에 취약하고 시간이 경과함에 따라 균열이 발생되어 누수의 원인이 되는 문제가 발생할 수 있었다. 이러한 문제점을 해결하기 위해 복합재료를 이용한 방수방법이 신기술로 인정되어 관공서나 각급 학교의 옥상 등에 시공되고 있는 실정이다. 그러나 이러한 복합재료의 경우에도 시간이 경과함에 의한 층간 소재의 변이, 연결조인트 접착불량, 바닥면과 벽체의 균열발생에 대한 재료의 추종성 등의 문제로 하자 발생이 나타남으로써, 복합재료를 이용한 방수방법으로 시공한 방수층의 내구연한이 10년을 초과하기는 어려운 문제가 있었다.The rooftop waterproofing method of the aggregate structure using the conventional waterproof lining construction method is mostly the rooftop waterproofing method using the non-exposed sheet, and the rooftop waterproofing method using the non-exposed sheet is leaked due to the crack of mortar layer after the completion of five years or more. There was a problem that began to occur, and most of them selected polyurethane exposure waterproofing as a repair method for such leaks, and additionally, PVC exposure sheet waterproofing and inorganic coating waterproofing were selected as repairing methods for leakage. It's happening. However, all of the conventional repairing methods for leaks are exposed waterproof methods, which have a problem that durability is decreased by about 3 to 7 years due to aging due to ultraviolet rays, and it is difficult to economically because it needs to be rebuilt in a short time. There is a high risk of occurrence. In particular, polyurethane exposure waterproofing begins to show problems such as bubble generation, cracking, and aging depending on the ground condition three years after construction, and the situation of re-installation occurs again in five to seven years. These problems are fundamental problems of polyurethane materials, that is, high reactivity with water, and aging caused by UV light when hardness is 60 (Shore A) or less. By aging), and problems such as a problem of a poor waterproof layer due to a poor mixing of a polyurethane main material and a curing agent. In addition, the waterproofing of PVC exposed sheet in the repair method of roof structure waterproofing of the aggregate structure may cause problems due to poor adhesion due to the passage of time between the interlayer adhesion sites, and the inorganic film waterproofing also has a weak elasticity of the coating waterproofing material. It is vulnerable to cracking and over time, cracking may occur, causing leaks. In order to solve this problem, the waterproofing method using the composite material is recognized as a new technology and is being installed on the roof of a government office or a school. However, even in the case of such composite materials, problems such as variations in interlayer materials over time, poor adhesion of connecting joints, and traceability of materials to cracking of floors and walls, etc. There was a problem that the durability of the waterproof layer constructed by the more than 10 years.

방수라이닝 시공방법은 에폭시 수지 또는 유리섬유를 보강한 열경화성 수지로 도포하는 습식방법과 스테인리스나 폴리에틸렌 계열의 방수시트 등을 부착 설치하는 건식방법으로 나눌 수 있는데, 에폭시 수지 또는 유리섬유를 보강한 열경화성 수지로 도포하는 습식방법은 현장작업이 어렵고 번거로울 뿐만 아니라 작업환경에 유해성이 존재하여 작업자의 안전에 위험이 발생될 우려가 있고, 균일한 방수품질을 확보하기 어려우며, 내구연한이 5년 전후로서 짧은 시간 안에 다시 재시공해야 하는 문제가 존재한다. 스테인리스나 폴리에틸렌 계열의 방수시트 등을 부착 설치하는 건식방법은 스테인레스를 이용하는 경우 스테인레스가 시공과정에서 발생할 수 있는 수분, 유기용제 및 기타 방수용화합물의 침투에 의해 변질되어 오염이 발생될 위험이 있고, 고가의 가격을 가지므로 경제성이 떨어지는 문제가 있고, 폴리에틸렌 계열의 방수시트를 이용하는 경우에는 폴리에틸렌 방수시트와 바닥면과의 접착력이 약하여 시간의 경과에 따라 들뜸이 발생할 위험이 있어 내구연한이 짧고, 방수시공과정에서 수분, 유기용제 및 기타 방수용화합물의 침투와 바닥면과의 결합에 의한 변형과 방수하자가 발생할 위험이 있고, 강도가 미흡하여 외부의 온도나 습도 등의 변화, 또는 외부의 충격이 의하여 2차 균열이 발생될 위험이 크고 바닥면 등에 발생한 1차 균열의 확산이 용이하여 내구성이 떨어지는 문제가 있었다. Waterproof lining construction methods can be divided into wet method of coating with epoxy resin or thermosetting resin reinforced with glass fiber and dry method of attaching stainless steel or polyethylene type waterproof sheet, etc., thermosetting resin reinforced with epoxy resin or glass fiber The wet method of application is difficult and cumbersome for on-site work, and there is a danger in the working environment due to the harmfulness in the working environment, and it is difficult to secure a uniform waterproof quality. There is a problem that needs to be rebuilt. In the dry method of attaching stainless steel or polyethylene-based waterproof sheet, the stainless steel is deteriorated by the penetration of moisture, organic solvent and other waterproofing compounds that may occur during the construction process. Because of its price, there is a problem of low economical efficiency, and in case of using the polyethylene-based waterproof sheet, the adhesion between the polyethylene waterproof sheet and the bottom surface is weak and there is a risk of lifting up over time. During the process, there is a risk of deformation and waterproofing defects due to penetration of moisture, organic solvents and other waterproofing compounds and bonding to the bottom surface, and insufficient strength, resulting in changes in external temperature or humidity, or external shocks. There is a high risk of secondary cracks and the spread of primary cracks on the floor There was a problem of poor durability.

By facilitating the thermal welding of the waterproof sheet and the high frequency induction heating plate, which is in close contact with the inner wall of the concrete water tank, the waterproof sheet is integrally bonded with the supporting member through the through hole penetrated through the high frequency induction heating plate. Since the sheet and the wall support member are made of the same material, the adhesive strength is higher than that of the dissimilar materials, so that deformation can be prevented from shrinkage / expansion due to the change of the water level stored in the concrete water tank, so that the user can improve the reliability of the product. PE lining of concrete water tank and its construction method A. PE lining of the concrete water tank and its construction method is difficult and cumbersome on-site work by using a high frequency heat fusion process, as well as requiring a difficult construction for the worker, there is a problem that the quality varies depending on the worker, waterproof construction process There is a risk of deformation and waterproof defects caused by penetration of moisture, organic solvents, and other waterproofing compounds and bonding to the bottom surface, and due to insufficient strength, changes in external temperature, humidity, etc. There is a risk of cracking and the spread of primary cracks occurring on the bottom surface, and the adhesion between the polyethylene waterproof sheet and the bottom surface is weak, so that a problem occurs over time and the durability remains poor.

The impact resistant waterproof layer 500 is composed of a polyurea waterproof layer 550 formed by applying a polyurea waterproof member 1.60 to 1.70kg / m 2 on the composite sheet 400, the anti-aging coating layer 600 is the polyurea waterproof layer It consists of an acrylic urethane coating layer 610 formed by applying an acrylic urethane coating member 0.20 ~ 0.25kg / m 2 on the top.

내충격성방수층(500)을 경도가 우수한 폴리우레아방수층(550)[경도 Shore A 70±5]으로 구성함으로써 향상된 방수성과 고내구성을 가지는 복합시트(400)를 경도가 우수한 폴리우레아방수층(550)에 의해 충분히 보호할 수 있고, 우수한 경도를 가져 내충격성을 가지는 폴리우레아방수층(550)을 이용해 외부 충격흡수하여 2차 균열 발생을 억제하고, 내마모성이 우수하고 자외선에 의한 분해에 저항하여 내구성이 우수한 폴리우레아방수층(550)의 방수성을 이용하여 복합시트(400)로의 수분흡수를 배제하므로 우수한 방수성과 내구성을 가지는 효과를 가진다. 또한 폴리우레아방수층(550)은 경화시간이 짧아(초속경성) 시공이 용이하고 물과 반응하지 않아 기포 발생의 위험이 없으며, 무휘발성의 무촉매 반응이므로 친환경적인 장점을 가진다. The impact resistant waterproof layer 500 is composed of a polyurea waterproof layer 550 having excellent hardness [hardness Shore A 70 ± 5], thereby making the composite sheet 400 having improved waterproofness and high durability into a polyurea waterproof layer 550 having excellent hardness. Can be sufficiently protected by the polyurea waterproof layer 550 having excellent hardness and absorbing external shock to prevent secondary cracking, and have excellent wear resistance and resistance to decomposition by ultraviolet rays. By using the waterproofness of the urea waterproof layer 550 to exclude the water absorption to the composite sheet 400 has the effect of having excellent waterproof and durability. In addition, since the polyurea waterproof layer 550 has a short curing time (ultra-high hardness), construction is easy and there is no risk of bubble generation because it does not react with water.

폴리우레아방수층(550)을 단일층으로 구성하는 이유는 폴리우레아방수부재의 점도가 높고 1.60∼1.70kg/m2로 도포되어 두께가 충분하여 2개의 층 형성을 이용하지 아니하여도 평탄한 폴리우레아방수층(550)이 바로 형성됨으로써, 노화방지용코팅층(600)과 적정한 결합력을 가질 수 있으며, 우수한 경도와 내충격성을 가지는 폴리우레아방수층(550)을 이용하므로 외부 충격에 의한 균열발생의 위험을 줄이고 옥상적재물에 의한 손상으로부터 방수층을 보호하는 효과도 가지며 공정효율성도 높은 장점을 가진다. 이 경우 노화방지용코팅층(600)은 상기 폴리우레아방수층(550) 상부에 아크릴우레탄코팅부재를 0.20∼0.25kg/m2 도포하여 형성된 아크릴우레탄코팅층(610)으로 구성된다. 아크릴우레탄코팅층(610)은 폴리우레아방수층(550)의 외부 자외선으로 인한 변색을 방지하므로, 본원발명인 향상된 방수성과 고내구성을 가지는 복합시트를 이용한 방수시공방법에 우수한 내구성을 부여하게 된다.The reason why the polyurea waterproofing layer 550 is composed of a single layer is that the polyurea waterproofing layer has a high viscosity and is applied at 1.60 to 1.70kg / m 2 , so that its thickness is sufficient so that the polyurea waterproofing layer is flat even without using two layers. Since the 550 is formed immediately, it may have an appropriate bonding force with the anti-aging coating layer 600, and the polyurea waterproof layer 550 having excellent hardness and impact resistance is used, thereby reducing the risk of cracking due to external impact and reducing the rooftop material. It also has the effect of protecting the waterproof layer from damage and has the advantage of high process efficiency. In this case, the anti-aging coating layer 600 is composed of an acrylic urethane coating layer 610 formed by applying an acrylic urethane coating member 0.20 to 0.25kg / m 2 on the polyurea waterproof layer 550. Since the acrylic urethane coating layer 610 prevents discoloration due to external ultraviolet rays of the polyurea waterproofing layer 550, excellent durability is given to the waterproof construction method using the composite sheet having improved waterproofness and high durability according to the present invention.

The polyurea waterproofing layer 550 formed by applying a polyurea waterproofing member 1.60 to 1.70kg / m 2 on the composite sheet 400 is less than the range of 1.60 to 1.70kg / m 2 and the polyurea waterproofing layer ( 550) When the coating range of the acrylic urethane coating layer 610 formed by applying 0.20 to 0.25 kg / m 2 of the acrylic urethane coating member on the upper surface is less than 0.20 to 0.25 kg / m 2 , the excellent hardness and resistance described in detail above. The effect of preventing external shock absorption and secondary cracking using impact properties, the effect of promoting waterproofing by excluding the water absorption to the composite sheet 400 by using the waterproofness of the polyurea waterproofing layer 550, excellent wear resistance and no Effect of having excellent durability and eco-friendliness by the volatile non-catalytic polyurea waterproofing layer 550 and preventing or preventing discoloration and decomposition due to external ultraviolet rays may occur. It said, there is a fear that the construction problems occur in the inventors waterproofing construction methods.

도 13에 의하면 상기 폴리우레아방수부재는 Methylene diphenyl diisocyanate-Polypropylene glycol prepolymer, 4,4'-Diphenylmethane diisocyanate 및 2,4'-Diphenylmethane diisocyanate를 포함하는 폴리우레아방수주제에 Polyester amine, Diethyltoluenediamine, Carbon black 및 Titanium dioxide를 포함하는 폴리우레아방수경화제가 혼합되어 형성될 수 있다. 이 경우 상기 폴리우레아방수주제는 Methylene diphenyl diisocyanate-Polypropylene glycol prepolymer 54 중량부, 4,4'-Diphenylmethane diisocyanate 23 중량부 및 2,4'-Diphenylmethane diisocyanate 23 중량부를 포함하여 구성되고, 상기 폴리우레아방수경화제는 Polyester amine 73 중량부, Diethyltoluenediamine 25 중량부, Carbon black 1 중량부 및 Titanium dioxide 1 중량부를 포함하여 구성하여 구성된다.According to FIG. 13, the polyurea waterproof member is polyester amine, diethyltoluenediamine, carbon black, and titanium in a polyurea waterproofing agent including Methylene diphenyl diisocyanate-Polypropylene glycol prepolymer, 4,4'-Diphenylmethane diisocyanate, and 2,4'-Diphenylmethane diisocyanate. Polyurea waterproofing hardeners containing dioxide can be formed by mixing. In this case, the polyurea waterproofing agent comprises 54 parts by weight of Methylene diphenyl diisocyanate-Polypropylene glycol prepolymer, 23 parts by weight of 4,4'-Diphenylmethane diisocyanate and 23 parts by weight of 2,4'-Diphenylmethane diisocyanate, and the polyurea waterproofing hardener Is composed of 73 parts by weight of polyester amine, 25 parts by weight of diethyltoluenediamine, 1 part by weight of carbon black and 1 part by weight of titanium dioxide.

상기 폴리우레아방수부재의 폴리우레아방수주제 및 폴리우레아방수경화제가 이상에서 설명한 지정된 구성요소를 가지지 아니하거나, 지정된 중량부를 벗어나게 되면 내충격성방수층(500)으로서의 폴리우레아방수층(550)의 형성 및 기능에 문제가 발생할 수 있다. 이 경우 폴리우레아방수층(550)의 우수한 경도[경도 Shore A 70±5]에 문제가 발생하여, 본원발명의 우수한 내충격성에 문제가 발생할 수 있다. 또한 폴리우레아방수층(550)을 이용한 외부 충격흡수가 미흡하여 2차 균열 발생이 발생할 우려가 크고, 내마모성에 문제가 발생할 가능성이 크다. 나아가 자외선에 의한 분해가 용이해져 본원발명의 내구성에도 문제가 발생하며, 폴리우레아방수층(550)의 방수성에 문제가 발생하여 복합시트(400)로의 수분흡수가 용이해지므로 방수성 및 내구성에 문제가 발생할 가능성이 커진다. 또한 폴리우레아방수층(550)의 경화시간이 길어져 시공이 어려워지고 물과의 반응에 의한 기포 발생의 위험이 커진다. 나아가 폴리우레아방수층(550)과 아크릴우레탄코팅층(610)의 결합력이 떨어져 결과적으로 본원발명인 향상된 방수성과 고내구성을 가지는 복합시트를 이용한 방수시공방법의 우수한 방수성과 내구성에 문제가 발생할 수 있다.When the polyurea waterproofing agent and the polyurea waterproofing hardener of the polyurea waterproofing member do not have the specified components described above or deviate from the designated weight parts, the formation and function of the polyurea waterproofing layer 550 as the impact resistant waterproofing layer 500 Problems may arise. In this case, a problem arises in the excellent hardness [hardness Shore A 70 ± 5] of the polyurea waterproof layer 550, which may cause a problem in the excellent impact resistance of the present invention. In addition, the external shock absorption using the polyurea waterproof layer 550 is insufficient, there is a high possibility that secondary cracks are generated, a problem in wear resistance is likely to occur. Furthermore, it is easy to decompose by ultraviolet rays, which causes problems in the durability of the present invention, and a problem occurs in the waterproofness of the polyurea waterproofing layer 550, so that the water absorption into the composite sheet 400 becomes easy, thereby causing problems in waterproofness and durability. The probability increases. In addition, the curing time of the polyurea waterproof layer 550 becomes longer, making construction difficult and increasing the risk of bubble generation due to reaction with water. Furthermore, the bonding force between the polyurea waterproof layer 550 and the acrylic urethane coating layer 610 may be reduced, resulting in problems of excellent waterproofness and durability of the waterproof construction method using the composite sheet having improved waterproofness and high durability.
