이러한 재도장의 일례로, 국내 등록특허공보 제10-2267627호에 교량구조물의 친환경 보수보강공법, 제10-2344283호인 교량 구조물 표면 보수 보강용 도장 시공 방법 등이 게시되어 있다.As an example of such repainting, Korean Patent Registration No. 10-2267627 discloses an eco-friendly repair and reinforcement construction method for bridge structures, and No. 10-2344283, a painting construction method for surface repair and reinforcement of bridge structures, and the like are posted.
상기 교량구조물의 친환경 보수보강공법은 도 1에 도시된 바와 같이 기존 도장재를 제거하기 위한 표면처리 수행단계와; 상기 표면처리된 면에 프라이머를 도포하여 프라이머층을 10 내지 20㎛의 도막두께로 하도를 형성하는 단계와; 아크릴 변성 실리콘 수지 및 무기질 안료를 기반으로 제작된 실리콘 도료를 50 내지 70㎛의 도막두께로 하여 중도를 형성하는 단계; 및, 수성 아크릴 에멀젼의 투명도료를 10 내지 30㎛의 도막두께로 도포하여 상도를 형성하는 단계로 이루어진다.As shown in FIG. 1, the eco-friendly repair and reinforcement method of the bridge structure includes a surface treatment step for removing the existing paint; applying a primer to the surface-treated surface to form a primer layer with a coating film thickness of 10 to 20 μm; Forming a middle coat with a silicone paint made based on an acrylic modified silicone resin and an inorganic pigment to a coating film thickness of 50 to 70 μm; and forming a top coat by applying a transparent paint of an aqueous acrylic emulsion to a coating film thickness of 10 to 30 μm.
상기 교량 구조물 표면 보수 보강용 도장 시공 방법은 도 2에 도시된 바와 같이 보수 보강 시공 방법이 실시될 장소를 시공시 발생하는 분진 비산을 막고 외부 먼지를 차단하는 분진차단 및 보호막을 설치하는 보양 단계와; 손상 피막 가진 도료층을 화학적 표면처리 또는 기계적 처리방법을 통하여 제거하고 제거된 구조물의 표면을 물로 고압 세척하거나, 마른 천으로 닦아낸후 알코올계 용제나 에나멜 신나로 세척하여 정리하는 표면 정리단계와; 에폭시계 도료로 하도층을 형성하되, 상기 하도층은 기존 도료의 제거된 구조물의 표면에 도장 실시되며, 도장두께는 기존 도료층 높이에 대응하는 높이로 실시되는 하도층 형성 단계와; 에폭시계 도료로 중도층 형성 단계; 및 수용성 불소수지 도료로 상도층 형성하는 상도층 형성 단계로 이루어진다.As shown in FIG. 2, the bridge structure surface repair and reinforcement painting construction method includes a maintenance step of installing a dust blocking and protective film to prevent dust scattering and block external dust generated during construction of the place where the repair and reinforcement construction method is to be performed, and ; A surface cleaning step of removing the paint layer with the damaged film through chemical surface treatment or mechanical treatment, cleaning the surface of the removed structure with water at high pressure, or wiping it with a dry cloth and then cleaning it with an alcohol-based solvent or enamel thinner; Forming an undercoat layer with an epoxy-based paint, wherein the undercoat layer is painted on the surface of the structure from which the existing paint is removed, and the paint thickness is carried out at a height corresponding to the height of the existing paint layer; Forming an intermediate layer with an epoxy-based paint; and a top coat layer forming step of forming a top coat layer with a water-soluble fluororesin paint.
그러나, 보수 도장 공법은 구도막을 화학적, 기계적 처리를 통해 모두 제거한 다음 신설 도막을 형성하는 관계로 상대적으로 많은 분진, 소음이 발생하고, 구도막이 모두 화학폐기물이기 때문에 환경에 치명적인 영향을 끼치는 문제점이 있으며, 상대적으로 많은 작업 시간과 비용이 발생하는 문제점이 있다.However, the repair painting method has a problem of having a fatal effect on the environment because a relatively large amount of dust and noise is generated because the old coating film is removed through chemical and mechanical treatment and then a new coating film is formed, and the old coating film is all chemical waste. However, there is a problem in that a relatively large amount of work time and cost occurs.

At this time, it is preferable to operate the supply and exhaust device, and a hot air dryer may be used depending on the outside air.
《건식 표면 처리 공정-S20》《Dry surface treatment process-S20》
구도막층(O)의 건조가 완료되면, 그라인더 장비(메탈툴 #60번)를 이용하여 건식 표면 처리를 통해 구도막층(O)의 표면에 프리이머의 부착 강도를 증대시키도록 스크래치(S)를 형성해서 단면적을 확대한다. 이때, 분진 흡입기를 그라인더 장비에 부착하여 분진 비산을 방지하는 것이 바람직하다.When the drying of the old coating layer (O) is completed, scratches (S) are applied to the surface of the old coating layer (O) to increase the adhesion strength of the primer through dry surface treatment using grinder equipment (metal tool #60). formed to enlarge the cross-sectional area. At this time, it is preferable to prevent scattering of dust by attaching a dust inhaler to the grinder equipment.
《부분 보수 공정-S30》《Partial repair process-S30》
건식 표면 처리가 완료되면, 구도막층(O)중 탈락 부분을 컷팅하거나 스크레퍼를 사용하여 완전 제거하고, 완전 제거 부위와 크랙, 핀홀이 발생된 부위에 구체 콘크리트(A)와 일체화되도록 에폭시계 퍼티를 사용하여 눈메꿈하여 평탄작업을 실시한다. 이때, 구체 콘크리트(A)에 크랙 발생으로 구도막층의 파손된 부분을 "V" 컷팅해서 크랙 진행을 방지하고, 구체 콘크리트(A)의 표면이 파손된 경우 에폭시계 또는 우레탄계의 레진 몰탈로 보수하여 양생시킨다. 적용되는 레진 몰탈의 pH값은 7~9의 범위를 갖는 것이 바람직하다.After the dry surface treatment is completed, cut the missing part of the old coating layer (O) or completely remove it using a scraper, and apply epoxy putty to the completely removed part and the part where cracks and pinholes have occurred to integrate with the concrete concrete (A). Use it to fill the eyes and perform leveling work. At this time, "V" cuts the damaged part of the old coating layer due to cracks in concrete concrete (A) to prevent crack progression, and if the surface of concrete concrete (A) is damaged, repair with epoxy or urethane resin mortar nurture The pH value of the applied resin mortar is preferably in the range of 7 to 9.
《프라이머층 시공 공정-S40》《Primer Layer Construction Process-S40》
부분 보수가 완료되면, 구도막층(O)과 신설 도막층(N)의 부착을 위해 스크래치(S)가 형성된 구도막층(O) 표면에 프라이머를 고임없이 최소한의 시공 두께로 일반 롤러나, 에어리스 롤러, 고무 헤라 등을 이용하여 도포하여 프라이머층(P)을 형성한 후 급배기장치를 동작시켜 함수율 6% 이하가 되도록 6시간 이상 건조시킨다. 이때, 프라이머는 투명의 에폭시계, 우레탄계, 아크릴계중 선택된 어느 하나이다.When the partial repair is completed, a general roller or an airless roller is used to attach the old coating layer (O) and the new coating layer (N) to the surface of the old coating layer (O) on which the scratches (S) are formed without applying primer to the minimum thickness. , After forming the primer layer (P) by applying it using a rubber spatula, etc., operate the air supply and exhaust device to dry it for 6 hours or more so that the moisture content is 6% or less. At this time, the primer is any one selected from transparent epoxy-based, urethane-based, and acrylic-based.
《신설 도막층 시공 공정-S50》《New coating layer construction process-S50》
프리이머의 양생이 완료되면, 프라이머층(P) 표면에 신설 도막을 균일하게 도포하고, 함수율 6% 이하가 되도록 5일 이상 건조시켜 신설 도막층(N)을 형성한다. 이때, 신설 도막은 음용수에 적합한 투명 또는 유색의 에폭시계, 세라믹계, 폴리우레아계중 선택된 어느 하나이다. 이때, 급배기장치를 동작시키는 것이 바람직하고, 외기에 따라 열풍 건조기를 사용할 수도 있다.When the curing of the primer is completed, a new coating film is uniformly applied on the surface of the primer layer (P), and dried for 5 days or more so that the moisture content is 6% or less to form a new coating film layer (N). At this time, the new coating film is any one selected from transparent or colored epoxy-based, ceramic-based, and polyurea-based suitable for drinking water. At this time, it is preferable to operate the supply and exhaust device, and a hot air dryer may be used depending on the outside air.
그리고, 신설 도막층 시공시 표면에 안개, 서리, 이물질 등이 내려앉지 않도록 보양 작업을 수행하며, 특히 지하 공간에서 발생할 수 있는 결로현상으로 인하여 신설 도막층의 부착불량이 발생됨으로 급배기장치로 결로를 제거후 시공하여야 한다.In addition, when constructing a new coating layer, maintenance work is performed to prevent fog, frost, foreign substances, etc. from settling on the surface. should be installed after removal.
