다기능 친환경 표면 마감 코팅제 조성물 및 이를 이용한 콘크리트 구조물 표면 마감 코팅 방법{VERSATILE ECO-FRIENDLY FINISHING COMPOSITION FOR COATING SURFACE AND COATING METHOD FOR COATING SURFACE OF CONCRETE STRUCTURE THEREWITH}TECHNICAL FIELD The present invention relates to a multi-functional eco-friendly surface-finishing coating composition and a method of coating a surface of a concrete structure using the same. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-

본 발명은 다기능 친환경 표면 마감 코팅제 조성물 및 이를 이용한 콘크리트 구조물 표면 마감 코팅 방법에 관한 것으로, 더욱 상세하게는 시공이 용이하고, 자기 보수성, 내식성, 난연성, UV 저항성, 내염해성, 중성화 저항성, 부착성, 동결융해저항성, 방수성 등이 우수하여 콘크리트 구조물의 공용기간 증가, 유지보수비용 절감 및 시공성 향상을 구현할 수 있는 다기능 친환경 표면 마감 코팅제 조성물 및 이를 이용한 콘크리트 구조물 표면 마감 코팅 방법에 관한 것이다.The present invention relates to a multifunctional environmentally friendly surface finishing coating composition and a method for coating a surface of a concrete structure using the same. More specifically, the present invention relates to a multifunctional environmentally friendly surface finishing coating composition, Freeze-thaw resistance, and waterproofness, thereby realizing an increase in the period of use of the concrete structure, maintenance cost reduction, and improvement of the workability, and a surface finishing coating method of a concrete structure using the same.

일반적으로 콘크리트 구조물에 균열이 발생하면 방수 성능 저하, 철근부식, 내구성 저하, 강도 저하 등으로 치명적인 결함을 초래할 수 있다. 콘크리트의 균열은 염해, 열화와 같은 외적 환경 원인, 설계하중, 소성수축 또는 건조수축과 같은 재료 특성, 배합조건, 시공적인 요인 등의 여러 가지 요인에 의하여 발생한다. 이와 같은 여러 가지 요인에 의해 콘크리트 구조물에 균열이 발생하면 콘크리트 구조물은 하중을 견디지 못하고 붕괴할 수 있다. 균열이 발생한 콘크리트 구조물에 대하여는 구조물의 안정성, 미관 등을 고려하여 방수성, 내구성 등을 회복하기 위한 보수작업이 필요하다.Generally, cracks in concrete structures can lead to fatal defects such as deterioration of waterproof performance, corrosion of reinforcing steel, deterioration of durability, and decrease of strength. Cracks in concrete are caused by various factors such as external environmental causes such as deterioration, deterioration, material properties such as design load, plastic shrinkage or drying shrinkage, mixing conditions, and construction factors. When cracks occur in the concrete structure due to various factors such as these, the concrete structure can collapse without being able to withstand the load. Concrete structures with cracks are required to be repaired in order to restore the waterproofness and durability in consideration of the stability and the beauty of the structure.

화학적 부식은 콘크리트가 외부에서 화학적 작용을 받아, 시멘트 경화체를 구성하는 수화 생성물을 변형 혹은 분해하여 결합 능력을 잃어버리는 열화 현상을 총칭한다. 이는 기존의 중성화, 동해, 염해에 의한 열화 현상과 혼동하기 쉬우며, 콘크리트 구조물에 내황산성 보수 모르타르가 아닌 기존의 보수용 모르타르로 타설됨으로써 결국 구조물에 균열 또는 박리 현상 등 성능 저하가 발생되어 내구성이 급격히 저하되는 경우가 빈번히 발생하고 있다.Chemical corrosion is a general term of deterioration phenomenon where concrete receives chemical action from the outside and deforms or decomposes the hydration products constituting the cement hardened body and loses its bonding ability. It is easy to be confused with the deterioration phenomenon by existing neutralization, East Sea and salting, and the concrete structure is not replaced with the sulfuric acid repair mortar, but the existing repair mortar is poured into the concrete structure, resulting in deterioration such as cracking or peeling in the structure, There are frequent occurrences of rapid decrease.

따라서, 산성, 중성화, 동해, 염해 등과 별도로 화학적 부식이 일어날 가능성이 맨홀 등에 사용되는 라이닝 및 코팅재 조성물에 대한 개발이 요구되고 있다.Accordingly, there is a demand for development of a lining and coating material composition which is likely to cause chemical corrosion separately from acidity, neutralization, corrosion, corrosion, and the like, and which is used for a manhole or the like.

일반적인 환경에서 화학적 부식 문제가 생기는 것은 확률적으로 매우 적으며, 생활 하수 등에 포함된 유기물이 세균에 의해 반응을 일으켜 황산 이온을 생성함으로써 콘크리트를 침식하는 경우가 대부분이다. 화학적 부식을 받는 구조물로는 수로, 수로터널, 하수 관련 구조물, 복개 구조물, 화학공장, 식품공장 등의 관련 구조물, 토양 오염 및 온천 지대의 지하 구조물 등을 들 수 있다.In general, it is probable that chemical corrosion problems occur very little, and most of the organic matter contained in domestic wastewater is reacted by bacteria to generate sulfate ion and erode the concrete. Structures subject to chemical corrosion include waterways, waterway tunnels, sewer related structures, closure structures, chemical structures, related structures such as food factories, soil contamination and underground structures in the hot springs.
