Description

콘크리트 표면 코팅 시공용 조성물 및 이를 이용한 콘크리트 표면 코팅 시공공법{Concrete surface coating composition and concrete surface coating method using the same}Concrete surface coating composition and concrete surface coating method using the same}

본 발명은 콘크리트 표면 코팅 시공용 조성물 및 이를 이용한 콘크리트 표면 코팅 시공공법에 관한 것이다. The present invention relates to a concrete surface coating construction composition and a concrete surface coating construction method using the same.

일반적으로 콘크리트 구조물의 기둥, 보, 벽체, 바닥은 거주자 혹은 이용자와 가장 활발하게 접하게 되는 이용 빈도가 매우 높은 구조부재로서 사람의 건강에 해롭지 않아야 하고, 상황에 따라 높은 물리적 강도, 내약품성, 내마모성, 부착성능 등이 요구되는 곳이다.In general, pillars, beams, walls, and floors of concrete structures are structural members that are most frequently used by residents or users, and should not be harmful to human health, and may have high physical strength, chemical resistance, and abrasion resistance depending on the situation. This is where adhesion performance is required.

현재 사용되는 콘크리트 구조물 마감재는 주성분에 따라 크게 유기계 마감재와 무기계 마감재로 구분할 수 있다. 유기계는 에폭시나 우레탄 수지를 사용한 제품이 대표적인데, 상온 경화형 가교결합을 형성하는 고분자타입으로 석유화학 유도품으로 제조되며, 질감이 우수하고 색상을 원하는 대로 거의 구현할 수 있으며, 균열발생이 적고 경우에 따라 탄성과 미끄럼방지 기능도 부여할 수 있으며, 건조가 빠르고 시공 후 유지관리도 비교적 손쉬운 제품이다.Currently used concrete structure finishing materials can be classified into organic finishing materials and inorganic finishing materials. The organic type is a product using an epoxy or urethane resin. It is a polymer type that forms a room temperature curing type crosslink, and is manufactured from petrochemical derivatives. It has excellent texture, can realize colors as desired, and has few cracks. Therefore, it can also provide elasticity and anti-slip function, and it is a product that is quick to dry and relatively easy to maintain after construction.

그러나, 에폭시, 우레탄 등의 유기계 코팅제는 유기 용제의 사용으로 인해 인체에 유해하고 작업환경을 열악하게 만들고, 유기계 코팅제로 형성된 바닥 코팅층은 소음 발생 및 가연성의 문제가 있다. 또한, 종래의 대부분의 바닥 코팅제는 수분과 접촉시 유해성분이 용출되고 화재발생시, 시공 후 양생 초기 휘발성유기화합물(VOC) 등의 유독가스가 방출되어 친환경적이지 못하여 식당 및 식자재 제조 공장 등은 물론 환경문제가 부각되는 사업장에는 시공하기 곤란하여 적용에 한계가 있었다. 특히, 에폭시의 경우 양생이 완료되더라도 에폭시 자체에 인체에 유해한 폐놀 수지 특히 비스페놀A 환경호르몬 등이 함유되어 있는 문제점이 있다.However, organic coating agents, such as epoxy and urethane, are harmful to the human body due to the use of organic solvents and make the working environment poor, and the floor coating layer formed of the organic coating agent has a problem of noise generation and flammability. In addition, most of the conventional floor coating materials are not environmentally friendly because harmful components elute upon contact with moisture and toxic gases such as volatile organic compounds (VOC) are released in the early stage of curing after construction. It is difficult to construct in the workplace where is highlighted, and its application was limited. Particularly, in the case of epoxy, even if curing is completed, there is a problem in that the epoxy itself contains waste-phenol resins, especially bisphenol A environmental hormone, etc., which are harmful to the human body.

또한, 종래의 유기계 코팅제는 콘크리트와의 접착성은 우수하지만 재료 자체의 강도가 크고 콘크리트와의 열팽창계수의 차가 커 사계절이 뚜렷한 우리 나라에서는 콘크리트와 코팅제가 계면에서 분리되거나 크랙이 발생하기 때문에 내구성이 저하되거나 하자 보수가 빈번해지는 등의 문제점이 있었다.In addition, the conventional organic coating agent has excellent adhesiveness to concrete, but in Korea, where the strength of the material itself is large and the difference in thermal expansion coefficient with concrete is distinct, the concrete and coating agent are separated at the interface or cracks, resulting in poor durability. There was a problem such as frequent or defective maintenance.

상기 무기계 마감제는 크게 분말 하드너와 무기계 액상 하드너류, 폴리머 시멘트 모르타르 등으로 분류될 수 있으며, 상기 분말 하드너는 저렴한 가격대비 비교적 우수한 성능을 나타내는데 콘크리트 타설시 콘크리트 소지면 위에 시공하는 일체감 있는 바닥재이므로 시공시기를 잘 맞추면 박리, 부분파손 등의 현상을 일어나지 않고 내구성이 매우 우수하며 시공의 질에 따라 성능과 외관의 차이를 많이 보이는 것으로 알려져 있으나 구조균열, 헤어균열의 발생 가능성이 높은 편이며 이에 따라 방진성능이 상대적으로 저하되고 제한적인 색상부여 및 탈색으로 저가형의 바닥재 개념에서 탈피하지 못하고 있는 실정이다.The inorganic finishing agent may be largely classified into a powder hardener, an inorganic liquid hardener, and a polymer cement mortar, and the powder hardener exhibits relatively excellent performance at an inexpensive price point. If it fits well, it does not cause phenomena such as peeling or partial breakage. It has excellent durability and is known to show many differences in performance and appearance depending on the quality of construction, but it is highly likely to cause structural cracks and hair cracks. Due to the relatively low and limited color application and discoloration, it is not possible to escape from the low-cost flooring concept.

폴리머 시멘트 모르타르는 기존 콘크리트 구조체 위에 시공하는 것이므로, 기존 콘크리트 바탕면에 직접 시공하게 될 경우, 접착성 및 수축 팽창율의 상이에 따른 탈락, 균열, 박리 등의 현상이 발생되므로, 이를 방지하기 위하여, 콘크리트구조물 바닥면에 먼저, 프라이머를 도포, 경화한 후, 프라이머 층 위에 폴리머 시멘트 모르타르를 도포 시공하여야 하는 문제점이 있었다.Since polymer cement mortar is applied on the existing concrete structure, when applied directly to the existing concrete base surface, phenomena such as dropping, cracking, and peeling due to differences in adhesiveness and shrinkage expansion rate occur, so to prevent this, concrete There was a problem in that a primer must be applied and cured on the bottom surface of the structure, and then a polymer cement mortar must be applied on the primer layer.

한편, 상기 유기계 마감재와 무기계 마감재의 경우, 콘크리트 면의 수분이 7중량%를 초과하는 경우 적용하기 어려워 콘크리트 면 시공 후 함수량이 6% 이하로 줄어들 때까지 시공을 할 수 없다는 단점을 갖는다.On the other hand, in the case of the organic-based finishing material and the inorganic-based finishing material, it is difficult to apply when the water content of the concrete surface exceeds 7% by weight, and has a disadvantage that the construction cannot be performed until the water content decreases to 6% or less after the concrete surface construction.

주차장, 공장바닥, 창고 등 자동차나 지게차가 지나는 바닥의 경우 대부분 유성 에폭시 마감재를 사용하고 있다. 유성 에폭시는 경도가 좋고 유광으로 외관상 좋아 보이지만 유성제품이여서 수분에 취약하여 함수율이 6% 이하의 콘크리트면에 도포 할 것이 추천되지만, 공사현장 사정상 함수율이 7중량% 이상인 경우가 많으며, 이렇게 함수율이 높은 상태에서 시공하는 경우 수분에 의해 접착력이 약화돼 탈착이 되는 경우가 빈번하게 발생 된다. 또한, 물기에 의해 미끄러움 현상 때문에 비가 오는 날에는 사고의 발생 위험도 높으며 2액형이여서 주제와 경화제의 정확한 계량이 필요하여 시공상 불편도 따른다. For floors where cars or forklifts pass, such as parking lots, factory floors, warehouses, etc., oil-based epoxy finishes are used. Oil-based epoxy has good hardness and looks good with gloss, but because it is an oil-based product, it is recommended to be applied to concrete surfaces with a moisture content of 6% or less because it is vulnerable to moisture.However, due to construction conditions, the water content is often 7% by weight or more. In the case of construction in the state, adhesion is weakened by moisture, and desorption occurs frequently. In addition, there is a high risk of accidents on rainy days due to slippery phenomenon due to water, and since it is a two-liquid type, it is necessary to accurately measure the subject and curing agent, which also leads to inconvenience in construction.

Then, PGMEA was added, heated to 70 ° C., and stirred under a nitrogen stream for 30 minutes. To this, 1.3 parts by weight of 2,2'-azobisisobutyronitrile (abbreviated as AIBN) was added to 100 parts by weight of the total monomers and polymerized for 18 hours. It was confirmed that the conversion ratio was 95% or more by analyzing the α-Cl monomer remaining in the reaction solution by gas chromatography. The obtained reaction solution was precipitated with hexane and dried in vacuo to isolate the copolymer. As a result of measuring the molecular weight of the obtained copolymer by GPC, the weight average molecular weight was 25,000.
