Description
본 발명은 대기오염 등 환경 변화로 인하여 이산화탄소와 반응한 콘크리트 건물의 급격한 중성화로 철근의 부식 등으로 인해 철근의 팽창압이 발생하고 콘크리트 건물의 균열이 발생하여 이로 인한 누수 현상이 발생하는 것을 방지하기 위해 전처리단계, 아크릴수지 및 물의 혼합물을 도포하는 단계, 고탄성 퍼티를 도포하는 단계, 이크릴 탄성 도막 방수제를 도포하는 단계, 아크릴 수지 및 실리콘 수지를 섞은 도료를 도포하는 단계로 구성된 콘크리트 중성화 방지와 방수도장을 통한 건물 수명 연장 공법에 관한 것이다.The present invention is to prevent the expansion pressure of the steel bars from occurring due to corrosion of the steel bars due to the rapid neutralization of concrete buildings reacting with carbon dioxide due to environmental changes such as air pollution, cracks in the concrete building, and water leakage due to this. Preventing neutralization and waterproofing of concrete, which consists of a pretreatment step, applying a mixture of acrylic resin and water, applying high elastic putty, applying an acrylic elastic coating waterproofing agent, and applying a paint mixed with acrylic resin and silicone resin. This is about a method of extending the life of a building through painting.
콘크리트 건물은 이산화탄소 등과의 화학적 부식환경, 중성화 및 염해 중성화에 의해 콘크리트 내부의 pH가 하락하게 되고 콘크리트 내부의 철근이 부식하게 되며, 철근의 부식은 철근의 팽창으로 이어져 결국 콘크리트 건물에 심각한 손상이 발생 할 수 있으므로, 구조물의 내구성 증진을 위해 단면복구나 표면보호와 같은 보수공법들이 사용되고 있다. 현재 이러한 보수공법은 전처리과정, 바인더와 물을 1:1로 섞은 아크릴 바인더 도료하는 단계, 신장률 150 ~ 180%의 퍼티를 도료하는 단계 및 아크릴 수성도장으로 마감하는 단계로 콘크리트 건물을 보수하는 방법이 일반적으로 사용되고 있다.In concrete buildings, the pH inside the concrete decreases due to the chemical corrosion environment with carbon dioxide, neutralization, and neutralization of salt damage, and the reinforcing bars inside the concrete corrode. Corrosion of the reinforcing bars leads to expansion of the reinforcing bars, ultimately causing serious damage to the concrete building. Therefore, repair methods such as cross-section restoration and surface protection are being used to improve the durability of the structure. Currently, this repair method consists of a pretreatment process, painting with an acrylic binder mixed with binder and water in a 1:1 ratio, painting with putty with an elongation of 150 to 180%, and finishing with a water-based acrylic paint. It is commonly used.
이러한 일반적인 보수방법은 기후 환경에 따라 다르지만 2 ~ 5 년에 만에 다시 보수해야 하는 문제점이 발생하고 있다.These general repair methods vary depending on the climate environment, but problems arise that require repairs every 2 to 5 years.
이러한 문제점을 해결하기 위하여 등록특허 10-2225331은 수성 퍼티 조성물로 균열을 보수하는 단계, 수성 아크릴계 프라이머를 도포하는 단계 및 수성의 통기성 상도 도료 조성물을 도포하는 단계를 포함하는 구조물의 도장 방법으로서,In order to solve this problem, Registered Patent No. 10-2225331 is a method of painting a structure comprising the steps of repairing cracks with a water-based putty composition, applying a water-based acrylic primer, and applying a water-based breathable topcoat composition,

It is significantly different, and problems with neutralization and waterproofing of concrete are likely to occur.

<일실시예><One embodiment>
노후화된 콘크리트 건물은 대기오염 등 환경 변화로 인하여 CO₂와 반응한 콘크리트 건물은 급격한 중성화로 철근의 부식으로 인한 팽창압이 발생하고 이에 따라 건물의 균열이 유발됨으로서 누수 현상이 발생한다.In aging concrete buildings, which react with CO₂ due to environmental changes such as air pollution, rapid neutralization causes expansion pressure due to corrosion of the reinforcing bars, which causes cracks in the building, resulting in water leaks.
이러한 노후화된 콘크리트 건물에서 벗겨진 페인트를 제거하고 부식된 철근이 돌출되어 있으면 철근의 부식된 부분을 제거하는 전처리 단계를 거친다. In these aged concrete buildings, peeling paint is removed and, if corroded rebar protrudes, a pretreatment step is taken to remove the corroded portion of the rebar.
두번째로 상기 전처리된 노후된 콘크리트 건물에 아크릴 수지와 물을 1: 4로 희석시켜 도포하는 단계를 거친다.Second, acrylic resin and water are diluted 1:4 and applied to the pretreated old concrete building.
상기 철근이 부식되어 있거나 콘크리트 건물에서 페인트가 많이 벗겨진 경우등 손상이 심한 경우 상기 희석된 아크릴 수지를 두껍게 도포하는 것이 바람직하겠다.If the rebar is corroded or the damage is severe, such as when a lot of paint has peeled off from a concrete building, it is preferable to apply the diluted acrylic resin thickly.
상기 도포된 희석된 아크릴 수지는 기도장된 수성도료를 안정화시키는 역활을 한다. The applied diluted acrylic resin serves to stabilize the applied water-based paint.
세번째로 상기 물에 희석된 아크릴수지를 도포한 다음 48시간 내외 경과 후 고탄성 퍼티를 도포하는 단계를 거친다.Third, the acrylic resin diluted in water is applied, and then after about 48 hours, high elasticity putty is applied.
상기 고탄성 퍼티는 신장률 400% 이상 사용하는 것이 바람직하겠으며 1㎜ 내외 정도 도포하며 상기 신장률 400% 이상의 고탄성 퍼티는 크랙 저항성을 가져 크랙을 방지하는 역활을 한다.It is desirable to use the high elasticity putty with an elongation of 400% or more and apply it to about 1 mm. The high elasticity putty with an elongation of 400% or more has crack resistance and plays a role in preventing cracks.
네번째로 상기 고탄성 퍼티를 도포한 후 상기 코탄성 퍼티가 마르는 시간을 확보하기 위해 통상적으로 48시간 이후에 아크릴 탄성 도막 방수제는 신장률 200% 이상 사용한다.Fourth, after applying the highly elastic putty, an acrylic elastic coating waterproofing agent with an elongation of 200% or more is typically used 48 hours later to ensure time for the highly elastic putty to dry.
상기 아크릴 탄성 도막 방수제는 중간 완충제로서 0.5㎜ 내외로 도포하여 상기 아크릴 탄성 도막 방수제는 망사형 크랙을 방지한다The acrylic elastic coating film waterproofing agent is applied as an intermediate buffer to a thickness of about 0.5 mm to prevent mesh-type cracks.
마직막 단계로 상기 아크릴 탄성 도막 방수제를 도포한 후 48시간 내외 경과 후 아크릴 수지 및 실리콘 수지를 섞은 도료를 도포하는 단계를 거친다,In the final step, after applying the acrylic elastic coating waterproofing agent, about 48 hours later, a paint mixed with acrylic resin and silicone resin is applied.
상기 물에 희석된 아크릴 수지, 상기 고탄성 퍼티, 상기 아크릴 탄성 도막 방수제를 도포 후 다음 작업 시간을 선택하는 것은 온도 및 습도 등 작업환경에 따라 48시간 내외 변동폭이 있을 수 있다.Selecting the next working time after applying the water-diluted acrylic resin, the high elastic putty, and the acrylic elastic coating waterproofing agent may vary by about 48 hours depending on the working environment such as temperature and humidity.
상기 아크릴 수지 및 실리콘 수지는 상기 아크릴 수지 100중량부 대비 상기 실리콘 수지 3중량부를 섞은 도료이며 신장률 400% 이상 사용한다, The acrylic resin and silicone resin are paints mixed with 3 parts by weight of the silicone resin compared to 100 parts by weight of the acrylic resin, and are used with an elongation of 400% or more.
상기 아크릴 수지 및 실리콘 수지 섞은 도료는 콘크리트의 중성화 방지 및 방수, 항곰팡이성을 증가시킨다.The paint mixed with the acrylic resin and silicone resin prevents neutralization and increases waterproofing and anti-fungal properties of concrete.
