More particularly, the present invention relates to an eco-friendly concrete coating composition comprising acrylic resin, water, quenching steel slag powder, quartz marble powder and kaolin powder, The present invention relates to an eco-friendly concrete coating composition which is capable of protecting concrete from cracking, tearing, neutralization, saltation and weathering caused by penetration of water and toxic chemicals by exhibiting waterproof and antifouling performance by resin, And a coating method.
일반적으로 콘크리트는 압축강도 및 내구성이 우수하여 토목 또는 건축 구조물, 즉 빌딩, 도로, 교량 등의 핵심 재료로 사용되고 있으나, 최근 다양한 환경요소, 특히 대기환경, 유해화학물질 또는 수분에 의하여 내구성에 약해져 그의 사용 수명이 빠른 속도로 단축되고 건축물의 미관 손상과 생활공간으로서의 거주성도 크게 저하되어 경제적으로 큰 손실을 가져온다. Generally, concrete is used as a core material for civil engineering or building structure such as building, road, bridge and the like because of its excellent compressive strength and durability. However, recently, due to various environmental factors, especially atmospheric environment, harmful chemical substance or moisture, The service life is shortened rapidly, the aesthetic damage of the building and the dwelling ability as a living space are largely lowered, resulting in a great economic loss.
특히, 방수 성능의 결함으로 누수되는 경우에는 압축 강도, 동결융해 저항성, 화학적 침식에 대한 저항성 등이 저하되어 콘크리트 구조물의 수명이 단축되고, 물리적, 화학적인 환경조건에 의한 열화 현상으로 콘크리트 구조물의 대대적인 보수나 재시공이 불가피하며, 이는 경제적으로 막대한 손실을 초래하고 있다.Particularly, when leakage occurs due to a defect in waterproof performance, the compressive strength, freeze-thaw resistance and resistance to chemical erosion are reduced, shortening the life of the concrete structure, deteriorating due to physical and chemical environmental conditions, Repair or rework is inevitable, and this leads to huge economic losses.
이에 따라, 최근에는 상기와 같은 콘크리트의 열화를 방지하기 위하여 다양한 도장시스템 또는 보수시스템이 개발되어 왔다. 종래 개발된 기술들을 살펴 보면, 한국등록특허 10-0629443호(2006년09월21일)에 전체 단량체 기준으로 메틸메타아크릴레이트 21~27 중량%, 부틸아크릴레이트 27.5~33.5 중량%, 2-에틸 헥실 아크릴레이트 18.6~24.6 중량%, 산값이 130~200을 구비하는 메틸메타아크릴레이트/아크릴산 수용성수지 18~24 중량%, 암모늄 퍼설페이트 0.5~1.2 중량%로 이루어진 것을 특징으로 하는 침투성 및 감수제 기능을 갖는 고내수성 콘크리트 표면 코팅제용 에멀션 수지 조성물이 공지되어 있다.Accordingly, in recent years, various coating systems or repair systems have been developed to prevent deterioration of the concrete. It has been found that, in the case of the conventional technologies, in the Korean Patent No. 10-0629443 (September 21, 2006), 21 to 27% by weight of methyl methacrylate, 27.5 to 33.5% by weight of butyl acrylate, A water-absorbent resin composition comprising 18 to 24% by weight of hexyl acrylate, 18 to 24% by weight of methyl methacrylate / acrylic acid water-soluble resin having an acid value of 130 to 200, and 0.5 to 1.2% by weight of ammonium persulfate. An emulsion resin composition for a high water-resistant concrete surface coating agent is known.
그러나, 상기 특허의 에멀젼 수지 조성물은 아크릴수지로만 조성되어 있고, 무기질 분체는 전혀 조성되어 있지 않으므로 콘크리트 구조체와 무기질 분체의 결합성이 발휘되지 않고, 단순히 아크릴수지가 콘크리트 구조체와 접착되어 쉽게 탈리되는 문제점이 여전히 남아 있어 콘크리트 보수 또는 코팅으로 인한 보호기능은 발휘할 수 없는 문제점이 있었다. However, since the emulsion resin composition of the above patent is composed only of acrylic resin and the inorganic powder is not constituted at all, the bondability between the concrete structure and the inorganic powder is not exerted and merely the acrylic resin adheres to the concrete structure, Is still present, so that there is a problem that the protection function due to concrete repair or coating can not be exhibited.
또한, 한국등록특허 10-0920245호(2009년09월28일)에는 콘크리트 구조물의 방수, 방식 및 열화방지를 위한 표면 코팅방법에 사용하는 세라믹 단면 보수재와 세라믹 방식코팅재 및 상도코팅재의 시스템 방식코팅법에서 1) 습윤 상태의 콘크리트 표면을 세라믹 단면 보수재로 100~200㎛ 두께가 되도록 메꿈작업하는 단계; 2) 세라믹 방식코팅재를 200~500㎛ 두께가 되도록 코팅하는 단계; 및 3) 실리콘아크릴 우레탄 도료를 이용한 상도코팅재를 40~60㎛ 두께가 되도록 코팅하는 단계; 를 포함하며, 상기 1) 단계에서 사용하는 세라믹 단면 보수재는 (a) 비스페놀 F형 에폭시수지 60 내지 80 중량부, 멜라민수지 5 내지 20 중량부 및 희석제 15 내지 20 중량부를 혼합한 주제; 및 (b) 변성방향족아민 10 내지 20 중량부, 변성방향족아민과 아닐린의 혼합물 60 내지 80 중량부 및 희석제 10 내 지 20 중량부를 혼합한 경화제;를 중량대비 (a):(b)가 5:1의 비율이 되도록 혼합하여 제조한 것임을 특징으로 하는 콘크리트 구조물의 표면코팅방법이 개발된 바 있다.Korean Patent Registration No. 10-0920245 (September 28, 2009) discloses a method of coating a ceramic cross-section, a ceramics-based coating material and a topcoat-based system-based coating material for use in a surface coating method for preventing waterproofing, 1) plugging the wet concrete surface to a thickness of 100 to 200 탆 using a ceramic cross-section repair material; 2) coating the ceramic type coating material so as to have a thickness of 200 to 500 탆; And 3) coating an upper coating material using a silicone acryl urethane paint to a thickness of 40 to 60 탆; Wherein the ceramic cross-section repairing material used in step 1) comprises: (a) 60 to 80 parts by weight of a bisphenol F type epoxy resin, 5 to 20 parts by weight of a melamine resin, and 15 to 20 parts by weight of a diluent; And (c) 10 to 20 parts by weight of a modified aromatic amine, 60 to 80 parts by weight of a mixture of a modified aromatic amine and aniline, and 20 parts by weight of a diluent 10, 1, the surface coating method of the concrete structure is developed.
그러나, 상기 특허는 여러가지 수지조성물을 사용하고, 특히 비스페놀 F형 에폭시수지와 변성방향족아민 및 희석제를 사용하여 친환경적이지 못할 뿐만 아니라 경제적으로도 문제가 있어 상용화되지 못하는 문제점이 있었다.However, the above-mentioned patent discloses that various resin compositions are used, and in particular bisphenol F type epoxy resin and modified aromatic amine and diluent are not environmentally friendly, and economically problematic, they are not commercialized.
또한, 한국등록특허 10-1004613호(2010년12월22일)에는 철근이 매설되어 있는 콘크리트구조물에 도포하는 프라이머와, 상기 프라이머의 상측에 도포하는 유연성을 가진 수용성 탑 코팅제로 이루어지며, 상기 수용성 탑 코팅제는 물 8.1 ∼ 10.5중량%, 부식억제제 0.2 ∼ 0.6중량%, 교차결합제 0.2 ∼ 0.4중량%, 증점제 0.3 ∼ 1중량%, 소포제 1 ∼ 1.6중량%, 습윤제 0.1 ∼ 0.3중량%, 이산화 티타늄 안료 7.5 ∼ 8.1중량%, 충진제 44 ∼ 46중량%, 라텍스 33.8 ∼ 35중량%를 포함하여 이루어진 것에 특징이 있는 유연성을 가진 수용성 아크릴 코팅제가 공지되어 있다.Korean Patent No. 10-1004613 (Dec. 22, 2010) discloses a waterproof top coating composition comprising a primer applied to a concrete structure having reinforcing bars embedded therein and a flexible water-soluble top coating agent applied on the top of the primer, The top coating agent may be selected from the group consisting of 8.1 to 10.5% by weight of water, 0.2 to 0.6% by weight of corrosion inhibitor, 0.2 to 0.4% by weight of crosslinking agent, 0.3 to 1% by weight of thickener, 1 to 1.6% by weight of defoamer, 0.1 to 0.3% by weight of wetting agent, A water-soluble acrylic coating agent having flexibility, which is characterized in that it comprises 7.5 to 8.1 wt%, 44 to 46 wt% of a filler, and 33.8 to 35 wt% of a latex.
그러나, 상기 특허의 아크릴 코팅제는 아크릴수지 에멀젼으로만 조성되어 있고, 무기질 분체는 전혀 조성되어 있지 않으므로 콘크리트 구조체와 무기질 분체의 결합성이 발휘되지 않고, 단순히 아크릴수지 코팅제가 콘크리트 구조체와 접착되어 쉽게 탈리되는 문제점이 여전히 남아 있어 콘크리트 보수 또는 코팅으로 인한 보호기능은 발휘할 수 없는 문제점이 있었다. However, since the acrylic coating agent of the above patent is composed only of the acrylic resin emulsion and the inorganic powder is not constituted at all, the bondability between the concrete structure and the inorganic powder is not exerted, and the acrylic resin coating agent is simply adhered to the concrete structure, There is still a problem that the protection function due to concrete repair or coating can not be exhibited.
또한, 한국등록특허 10-1368737호(2014년02월24일)에는 산성 실라놀 졸 용액과 알칼리성 실라놀 졸 용액을 혼합하되, 상기 산성 실라놀 졸 용액과 알칼리성 실라놀 졸 용액을 각각 97~70 : 3~30 중량비로 혼합하여 구성되는 콘크리트 구조물 침투형 코팅제 조성물에 있어서, 상기 산성 실라놀 졸 용액의 조성물로는 MTMS, GPTMS, 알콜, 탈이온수, 염산으로 이루어짐을 특징으로 하는 콘크리트 구조물 침투형 코팅제 조성물이 공지되어 있으나, 상기 조성물은 염산을 포함하여 인체에 유해하고 작업환경이 위험할 뿐만 아니라, 콘크리트에 침투되는 성질로 인하여 콘크리트 표면코팅효과가 발휘되지 않으므로 콘크리트 표면보호에는 불가능한 문제점이 있었다.Korean Patent No. 10-1368737 (Feb. 24, 2014) discloses a method in which an acidic silanolol sol solution and an alkaline silanolol sol solution are mixed, wherein the acidic silanolol sol and the alkaline silanolol sol are dissolved in 97 to 70 : 3 to 30 weight ratio, wherein the composition of the acidic silanolol sol solution is selected from the group consisting of MTMS, GPTMS, alcohol, deionized water and hydrochloric acid. However, since the composition contains hydrochloric acid, it is harmful to the human body and it is not only dangerous to work environment but also penetrates into concrete, so that the effect of surface coating of concrete is not exhibited.
