본 발명은 아크릴 탄성 방수제와 실리콘 페인트의 결합으로 건물 수명 및 도장주기의 연장공법에 관한 것으로서, 보다 상세하게는 아크릴 탄성 방수제와 실리콘페인트의 결합 공법을 통해 내후성 및 부착성을 향상시키고, 발수성을 부여함으로써 수분침투를 억제하여 건물의 내구성을 크게 향상시켜, 재도장 주기를 연장하여 유지수선비용을 절감하도록 한 아크릴 탄성 방수제와 실리콘 페인트의 결합으로 건물 수명 및 도장주기의 연장공법에 관한 것이다.The present invention relates to a method of extending the life of a building and a coating cycle by combining an acrylic elastic waterproofing agent and a silicone paint. More specifically, the present invention relates to a method for improving the weatherability and adhesion of acrylic water- The present invention relates to a method of extending the life of a building and a painting cycle by combining an acrylic elastic waterproofing agent and a silicone paint, which is capable of suppressing moisture penetration and greatly improving the durability of a building,

일반적으로, 신축 건물의 경우 외벽이 노후되는 것을 방지함과 동시에 미려감을 향상시키기 위해 석재 혹은 페인트로 도장처리 되는 경우가 대부분이다.Generally, in the case of a new building, it is most often painted with stone or paint to prevent the outer wall from being aged and to improve the feeling of touch.

상기 방법 중 석재를 이용하여 마감하는 경우에는 외관이 수려한 장점을 가지고 있으나, 석재의 자중에 의해 건축물의 하중이 증가되며, 운반과 시공이 용이하지 못하고, 그로 인한 비용 증가의 단점이 있었다.Among the above methods, the finishing using the stone has the advantage of having a good appearance, but the load of the building is increased due to the weight of the stone, the transportation and the construction are not easy, and the cost is increased.

한편, 일반 페인트를 이용하여 외벽에 도장 처리하는 것은 가격이 저렴하고, 다양한 색감을 연출할 수 있는 장점이 있으나, 내후성이 약하고 도장 후 대략 3 ~ 4년 주기로 재도장을 해야 되는 단점이 있다.On the other hand, the painting on the outer wall using general paint is advantageous in that it is cheap and can produce various colors, but has a disadvantage that it is poor in weatherability and must be re-coated in a period of about 3 to 4 years after painting.

특히, 신축 건물의 경우에는 외벽이 깨끗한 상태이나, 재도장을 수행하는 리모델링 건물의 경우에는 노후화 및 열화현상 등으로 인해 외벽에 균열이 발생하게 되며, 균열부위로 빗물이 흘러가게 되면, 철근 등을 부식시키는 원인을 제공하기도 한다. 이로 인해, 주기적으로 재도장 작업을 하더라도, 단순한 재도장 작업만으로는 외벽의 노후화가 점차 빨라지는 것을 방지할 수는 없었다. 즉, 대한민국 특허등록번호 제10-0579939호(2006.05.15. 공고)의 고층건물의 외벽 도장시스템 및 도장공법을 참조로 하면, 외벽에 도장작업시 페인트가 비산되는 것을 방지하고자 작업대를 제안하고 있다. 이 공법에 의해 페인트의 비산을 억제할 수 있는 장점이 있으나, 단순히 외벽에 도장 작업하는 것으로는 건물 외벽의 노후화 속도를 줄이거나, 재도장 주기를 연장하는 것은 불가능한 단점이 있었다.Particularly, in the case of a new building, the outer wall is clean, but in the case of a remodeling building which performs the repainting, cracks occur on the outer wall due to aging and deterioration phenomenon. When rainwater flows into the crack, It also provides the cause of corrosion. Therefore, even if the repainting work is performed periodically, it is not possible to prevent the outer wall from being aged gradually by a simple repainting operation. That is, referring to the outer wall painting system and painting method of a high-rise building of Korean Patent Registration No. 10-0579939 (published on May 15, 2006), a work table is proposed in order to prevent paint from scattering during painting work on the outer wall . This method has an advantage of suppressing scattering of paint, but it has a disadvantage that it is impossible to reduce the aging speed of the outer wall of the building or extend the repainting cycle by simply painting the outer wall.

본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로서, 개선된 공법을 통해 시멘트 구조물의 흡습 차단과 내후성 및 부착성을 향상시키고, 발수성을 부여함으로써 수분침투를 억제하여 건물의 내구성을 크게 향상시켜, 재도장 주기를 연장할 수 있도록 한 아크릴 탄성 방수제와 실리콘 페인트의 결합으로 건물 수명 및 도장주기의 연장공법을 제공하고자 한다.The present invention has been conceived to solve the problems described above. It is an object of the present invention to improve the durability of a building by suppressing moisture penetration by improving waterproofing, weathering and adhesion of a cement structure, It is intended to provide a method of extending the life of the building and the coating cycle by combining an acrylic elastic waterproofing agent and silicone paint to extend the repainting cycle.

도 1의 "가" 내지 "라"는 본 발명의 바람직한 일실시예에 따른 아크릴 탄성 방수제와 실리콘 페인트의 결합으로 건물 수명 및 도장주기의 연장공법을 보인 개략도이고, 도 2의 "가" 및 "나"는 본 발명의 바람직한 일실시예에 따른 충진공정을 보인 개략도이다.1 is a schematic view showing a method of extending the life of a building and a painting cycle by combining an acrylic elastic waterproofing agent and a silicone paint according to a preferred embodiment of the present invention. Is a schematic view showing a filling process according to a preferred embodiment of the present invention.

먼저, 도 1의 "가" 내지 "라"를 참조로 하면, 본 발명의 아크릴 탄성 방수제와 실리콘 페인트의 결합으로 건물 수명 및 도장주기의 연장공법은 크게 4단계의 공정을 통해 이루어진다.First, with reference to FIGS. 1 to 3 of FIG. 1, the life extension of the building and the extension of the coating cycle by combining the acrylic elastic waterproofing agent of the present invention and the silicone paint are largely accomplished through four steps.

첫째, "가"에서 도시하는 준비공정(S1)으로, 콘크리트 구조물(10)의 외벽에 발생된 크랙(12) 부분의 소지면에 발생된 구도막, 콘크리트 파편 등을 제거하여 매끈한 소지면을 가지도록 하는 것이다. 헤라, 철브러쉬, 그라인더 등의 각종 도구를 이용하여 손쉽게 제거할 수 있으며, 보다 정밀한 제거를 위해서는 핸드그라인더를 사용하는 것이 바람직하다.First, in the preparing step S1 shown in Fig. 1, the concrete film, concrete fragments, and the like generated on the surface of the crack 12 generated on the outer wall of the concrete structure 10 are removed to have a smooth surface . It can be easily removed by using various tools such as hera, iron brush, and grinder, and it is preferable to use a hand grinder for more precise removal.

둘째, "나"에서 도시하는 충진공정(S2)으로, 상기 준비공정(S1)에서 정리된 크랙(12) 공간에 반죽물 형태의 준탄성퍼티를 충진하여 충진층(20)을 형성하는 공정이다. 이때, 상기 충진층(20)은 충진 후, 굳어지기 전 가운데 부분을 볼록하게 형성하면서 그 표면에 다수의 요철부(22)가 형성되도록 형성하는 것이 더 바람직한데, 이는 이후 공정에서 도포되는 방수층과 부착성 향상을 도모하기 위해 제안된 것으로, 하기에서 다시 언급하기로 한다.Second, in the filling step S2 shown in FIG. 2B, a quasi-elastic putty in the form of a kneaded water is filled in the crack 12 space defined in the preparation step S1 to form the filling layer 20 . In this case, it is more preferable that the filling layer 20 is formed such that a central portion thereof is convexly formed before filling, and a plurality of uneven portions 22 are formed on the surface of the filling layer 20, It is proposed to improve the adhesion, and will be described later.

한편, 상기 준탄성퍼티는 신장율 80% 이상이며, 특수 아크릴 에멀젼 수지와 적절한 안료를 사용하여 도막에 탄성을 부여한 면처리용 퍼티로써, 내수성, 내알칼리성, 작업성 등이 우수한 제품으로, 건축물의 내/외부 균열부분의 보수용으로 널리 사용되고 있는 제품이다.On the other hand, the quasi-elastic putty has an elongation of not less than 80% and is a surface treatment putty imparting elasticity to a coating film using a special acrylic emulsion resin and a suitable pigment. The product is excellent in water resistance, alkali resistance, workability, / It is widely used for maintenance of external crack part.

셋째, "다"에서 도시하는 방수공정(S3)으로, 상기 충진공정(S2)에서 충진된 충진층(20)의 외면에 신장율 350%이상의 방수제를 도포하여 방수층(30)을 형성하는 공정으로, 이미 크랙(12)이 발생되어 보수한 부분으로 빗물이 스며드는 것을 원천적으로 차단하기 위한 공정이다. 이때, 상기 충진층(20)의 표면이 볼록하면서 다수의 요철부(22)가 형성되어 있으므로, 도포된 방수층(30)과 접착력이 극대화되어 외부 열화현상 등의 영향을 받더라도 쉽게 떨어지지 않는 장점이 있을 것이다.Thirdly, in the waterproofing step (S3) shown in " C, " the waterproofing layer 30 is formed by applying a waterproofing agent having a elongation of not less than 350% to the outer surface of the filling layer 20 filled in the filling step S2, It is a step for originally cutting off the penetration of the rainwater into the repair part where the crack 12 has already been generated. At this time, since the surface of the filling layer 20 is convex and a large number of concave and convex portions 22 are formed, the adhesive strength with the applied waterproof layer 30 is maximized, and even if it is affected by external deterioration phenomenon, will be.

한편, 상기 방수제는 아크릴 탄성도막 방수제를 사용하게 되는데, 시공이 간편하고 공기단축이 가능하면서도 방수 신뢰성이 높은 방수제이다.On the other hand, the waterproofing agent uses an acrylic elastic coating waterproofing agent. It is a waterproofing agent having a simple construction and shortening of air and a high waterproof reliability.

마지막 넷째, "라"에서 도시하는 페인팅공정(S4)으로, 상기 방수공정(S3)에서 형성된 방수층(30)을 포함한 콘크리트 구조물(10) 전체의 표면에 실리콘 페인트를 도포하여 실리콘층(40)을 형성하는 공정이다.Lastly, in the painting process S4 shown in FIG. 4, a silicon paint is applied to the entire surface of the concrete structure 10 including the waterproof layer 30 formed in the waterproof process S3, .

이때, 도포되는 실리콘 페인트는 발수성, 내오염성이 뛰어나 콘크리트 외벽이 오염되는 것을 방지할 수 있고, 그로 인해 재도장 주기를 연장할 수 있는 장점이 있다. 특히, 발수성이 좋아 콘크리트 외벽에 함유되어 있는 수분은 외부로 방출시키고, 외부에서 침투하는 물은 차단함으로써 부풀음 및 기포 발생을 억제할 수 있어 장시간 사용이 가능한 장점이 있다.At this time, the applied silicone paint is excellent in water repellency and stain resistance and can prevent the outer wall of the concrete from being contaminated, thereby extending the repainting cycle. Particularly, since the water contained in the outer wall of the concrete is excellent in water repellency, the water is released to the outside and the water penetrating from the outside is blocked, so that the swelling and the bubbling can be suppressed.

물론 상기 실리콘층(40)도 발수 기능이 있으나, 크랙(12) 부분에는 별도의 방수층(30)이 형성되어 있는데, 이는 크랙(12) 부분은 그 자체로 약해져 있으므로 이 부분은 완벽하게 방수함으로써 약해진 부분에서 연속적으로 발생될 수 있는 크랙(12)을 억제하기 위한 것이다.Of course, the silicon layer 40 also has a water-repellent function, but a separate waterproof layer 30 is formed in the crack 12, because the crack 12 itself is weakened, In order to suppress the crack 12 that can be generated continuously in the portion.

여기서, 상기 방수공정(S3) 전, 아크릴수지 프라이머(Primer)를 도포하는 도포공정이 더 포함될 수 있는데, 이는 방수제 도포 전 그 부분을 안정화시킴과 더불어 접착력을 더 향상시키기 위해서이다.Here, an application step of applying an acrylic resin primer may be further included before the waterproofing step (S3) in order to stabilize the part before applying the waterproofing agent and to further improve the adhesion.

한편, 상기 충진공정(S2)에서, 충진층(20)의 표면 형상은 도 2에서 도시하는 바와 같이 형성할 수 있다.On the other hand, in the filling step S2, the surface shape of the filling layer 20 can be formed as shown in Fig.

즉, "가"를 참조로 하면, 콘크리트 구조물(10)에 형성된 크랙(12)에 충진되는 준탄성퍼티를 충분히 삽입하여 전체를 볼록하게 형성되도록 한 다음, 오목한 곡면부(52)가 형성되면서 그 곡면부(52)에 다수의 요철(54)이 형성된 곡면요철헤라(50)를 구조물(10) 표면에 맞대고 밀게 되면 "나"에서 도시하는 바와 같은 충진층(20)의 표면 형상을 전술한 바와 같이 가운데 부분이 볼록하면서 다수의 요철부(22)이 형성된 타입으로 쉽게 형성할 수 있게 되는 것이다.In other words, referring to Fig. 3A, the quasi-elastic putty filled in the crack 12 formed in the concrete structure 10 is sufficiently inserted to form a convex shape, and then the concave curved surface portion 52 is formed, When the curved surface irregularity hara 50 in which a plurality of irregularities 54 are formed on the curved surface portion 52 is pushed against the surface of the structure 10, the surface shape of the filling layer 20 shown in " It is possible to easily form a plurality of convex-and-concave portions 22 having a convex central portion.

결국, 콘크리트 구조물(10)에 형성된 크랙(12)에 충진층(20)을 형성하여 보수하고, 그 외면에 방수층(30)을 형성한 뒤 실리콘층(40)을 형성하는 새로운 공법을 제안하면서, 특히 충진층(20)의 표면을 볼록하게 하면서도 다수의 요철부(22)를 형성하여 방수층(30)과의 부착력을 크게 향상시키되 실리콘 페인트로 인해 발수성, 내오염성이 향상되어 재도장 주기를 늦출 수 있는 장점이 있다. 또한, 곡면요철헤라(50)를 매개로 충진층(20)의 형상을 편리하게 형성할 수 있어 작업능률도 향상될 것이다.As a result, a new method of forming and repairing the filler layer 20 in the crack 12 formed on the concrete structure 10, forming the waterproof layer 30 on the outer surface thereof, and then forming the silicon layer 40, Particularly, the surface of the filling layer 20 is convex, and a large number of recesses / projections 22 are formed to greatly improve the adhesion with the waterproof layer 30. However, due to silicone paint, water repellency and stain resistance are improved, There is an advantage. In addition, the shape of the filler layer 20 can be formed easily through the curved surface irregularities 50, and the work efficiency will also be improved.
