Description
본 발명은 친환경 고고형분의 무용제 에폭시 프라이머 조성물에 관한 것이다.The present invention relates to an environmentally friendly, high-solids, solvent-free epoxy primer composition.
현재 국내 아파트, 할인매장 등의 건축물 주차장 바닥 마감재와 공장 바닥 도장 마감재로 사용되고 있는 에폭시 도료 제품은 크게 몇 가지로 형성되어 있다.Currently, there are several types of epoxy paint products that are used as floor finishing materials for building parking lots such as apartments and discount stores in Korea, and as finishing materials for factory floor coatings.
첫 번째로는 시공두께가 0.1~0.3mm로 마감되는 에폭시 코팅제로서 주로 아파트, 빌라, 할인매장 등에 사용되고 있으며 시공두께가 얇은 관계로 박막형 에폭시 마감재라고도 한다. 얇은 도막두께로 마감되고 있기 때문에 시공 후 수년이 지나면 통행량이 많은 코너나 램프부위부터 마모되거나 벗겨지는 문제점을 가지고 있으며 소지면의 요철 등으로 인하여 미관상태도 좋지 못하는 단점을 가지고 있으나 시공단가가 가장 저렴하기 때문에 아직까지 건축 현장에 많이 적용되고 있다.The first is an epoxy coating agent with a construction thickness of 0.1 to 0.3 mm. It is mainly used in apartments, villas, discount stores, etc. It is also called as a thin film epoxy finishing material because of its thin construction thickness. Since it is finished with a thin film thickness, it has a problem of worn or peeled off from corners or lamp parts which have a lot of traffic after years of construction, and has a disadvantage in that the cosmetic appearance is not good due to unevenness of the surface. However, It is still applied to construction sites.
두 번째로는 에폭시 라이닝 바닥 마감재로서 보통 2~3mm의 도막두께로 시공되고 있다. 품질이 우수하여 고급건물이나 상업시설 등에 주로 사용되고 있으며 시공두께가 두껍게 마감되기 때문에 미관적으로도 아름다우며 고강도 기능성을 가지고 있어서 시공한 후 반영구적으로 사용할 수 있고 에폭시코팅제보다 품질이 우수한 만큼 시공비가 최소 3배 이상 정도의 제품이다.Secondly, epoxy lining flooring is usually applied with a film thickness of 2 ~ 3mm. It is used mainly in high-grade buildings and commercial facilities due to its excellent quality. It is beautiful in beauty because it is thick in construction and has high strength functionality. It can be used semi-permanently after construction. It is superior in quality than epoxy coating, Or more.
세 번째로는 에폭시수지와 평균입도 0.4~1.5㎜의 규사를 혼합하여 주차장바닥, 공장바닥 등에 미장하여 마감하는 에폭시 레진몰탈공법이 있다. 이 에폭시 레진몰탈은 주성분이 규사이기 때문에 에폭시계 바닥 마감재 중에서는 강도 및 내마모성이 가장 좋은 제품이며 중장비공장이나 화물터미널 등과 같은 고 중량의 이동이 빈번한 곳에 사용되고 있다. 규사로 마감되는 공법이기 때문에 표면상태가 매끄럽지 못하여 쉽게 오염이 되는 단점을 가지고 있는 반면 미끄럼 방지 기능의 장점 또한 가지고 있다. 공사비는 최소 3mm 이상의 두께로 시공해야 하기 때문에 에폭시 라이닝 바닥 마감재보다는 좀 더 고가(高價)이다.The third is epoxy resin mortar method which mixes epoxy resin and silica sand with average particle size of 0.4 ~ 1.5mm and finishes on the parking lot floor and factory floor. Because epoxy resin mortar is the main component of silica, it has the best strength and abrasion resistance among epoxy based floor finishes and it is used in places where heavy and frequent movements such as heavy equipment factories and cargo terminals are used. It has a disadvantage that it is easily contaminated because the surface condition is not smooth because it is closed with sandpaper, but it also has the advantage of anti-slip function. The construction cost is higher than the epoxy lining flooring finishing because it needs to be constructed with a minimum thickness of 3mm.
그러나 상기 종래기술들은 모두 공통적으로 VOCs(휘발성유기화합물)을 많이함유하는 용제형 에폭시 프라이마를 선행 도장하는 방법으로서 인체에 유해하고 환경파괴의 원인이 되고 있다. 환경부 산하에 2005년 설립된 수도권 대기환경청은 순차적으로 도료 내에 포함되어 있는 휘발성 유기화합물의 사용량을 대폭적으로 감소시켜 생산하도록 각 제조업체에 기준을 제시하였고 그 기준에 적합한 제품만 수도권 내에서 사용할 수 있도록 법제화하였을 정도로 친환경적인 정책을 펼치고 있다. 이 때문에 도료 제조 업체에서는 수용성 에폭시 및 하이솔리드제품(고고형분)을 개발해오고 있다.However, all of the above-mentioned prior art methods are commonly used as a method of preceding painting a solvent-type epoxy primer containing a large amount of VOCs (volatile organic compounds), which is harmful to the human body and causes environmental destruction. Established in 2005 under the Ministry of Environment, the Metropolitan Air and Environmental Authority proposes standards for each manufacturer in order to reduce the amount of volatile organic compounds contained in paints sequentially. Which is environmentally friendly. For this reason, paint manufacturers have developed water-soluble epoxy and high solid products (high solid content).
또한 2016년 12월 도입된 “건축자재 사전적합확인제도”에서는 다중이용시설 또는 공동주택의 신축(개.보수를 포함)할 때에는 건축자재가 기준을 초과하는지 여부를 사전에 확인한 후 사용하여야 한다. 또한 건축자재를 제조 또는 수입하는 자도 건축자재를 공급할 때에는 기준 초과 여부를 확인 받은 후에 공급하여야한다. 특히 지하 주차장은 구조적 환경 때문에 VOCs(휘발성유기화합물)의 발생 시 환기가 상대적으로 어렵고, 습한 조건으로 도막의 들뜸, 크랙, 부풀림 현상 등이 많이 발생 한다. 현재 수용성 에폭시 프라이마 등의 친환경적인 에폭시 제품들은 다양하게 개발되어 있으나, 이러한 제품 들은 바닥 소지 침투력이 약하고 습한 조건일 때 도료가 완전히 건조되지 않거나 소지에 깊이 침투하지 못하여 마감도장 후 최종적으로 부착강도에 큰 문제를 발생시킬 수 있다. 또한 재도장에서도 기존 바닥면의 오염원을 완전히 제거하지 못하면 쉽게 도막이 박리되는 현상을 초래한다. In addition, in the "Preliminary Compliance Checking Scheme for Building Materials" introduced in December 2016, when constructing (including repairing) multi-use facilities or apartment buildings, it is necessary to confirm beforehand whether the building materials exceed the standard. Also, those who manufacture or import building materials should supply them after confirming whether they exceed the standard. In particular, underground parking lots are relatively difficult to ventilate when VOCs (Volatile Organic Compounds) are generated due to the structural environment, and there are many cases of lifting, cracking, and swelling of the coatings under wet conditions. Currently, eco-friendly epoxy products such as water-soluble epoxy primers have been developed variously. However, these products have poor penetration ability of bottom sole, and when the paint is not completely dried or penetrate deeply into the substrate under wet conditions, It can cause a large problem. Also, in the case of recoating, if the contaminants of the existing floor surface can not be completely removed, the coating film easily peels off.
현재 에폭시 바닥 도장공법에서 하도도료(프라이마) 도장 공정은 기초공사가 되는 중요한 단계로 용제를 함유하지 않은 하도도료(프라이마)는 시장에서 넓게 상용화 되지 않았다.Currently, the epoxy coating process is an important step in the foundation process, and the solvent-free primer coating (primer) has not been widely commercialized in the market.
따라서 친환경적인 고고형분의 무용제 에폭시 프라이머 도료를 이용한 바닥마감재를 개발할 필요가 있다. Therefore, there is a need to develop a floor finish using an environmentally friendly, high-solids, solvent-free epoxy primer coating.
이에 본 발명은 VOCs(휘발성유기화합물), 용해물질인 용제 성분을 포함하지 않는 하도(프라이머)로 콘크리트면, 시멘트 면과 같은 소지에 프라이마(하도)로 소지면에 침투하여 콘크리트나 시멘트 면의 강도를 증강시키고 후속 도료와의 부착성을 향상시킨다. Accordingly, the present invention relates to a method for producing a cement composition, which is a primer that does not contain VOCs (volatile organic compounds) and a solvent component as a dissolving substance, penetrates into a base surface such as a concrete surface or a cement surface, And improves adhesion with subsequent coatings.
기존 도장되어진 면의 제거나 기존 도막의 피해를 발생시키지 않으면서 용 해없이 우수한 부착성 발현. 해당 부위를 녹이지 않고 부착하여 상도 도장 시 들뜸 및 박리 현상이 없고 부착력이 우수하면서도 강인한 도막 형성으로 최종 도막 형성 후 충격이나 밀림, 박리 등에 대한 저항성이 우수하다. Excellent adhesion without dissolving existing coatings or without damaging existing coatings. It is free from peeling and peeling phenomenon in the top coating by attaching the relevant part without melting, and it is excellent in resistance to impact, bending and peeling after formation of final coating film by forming strong film with excellent adhesion.
고 고형분의 하도도료로 콘크리트면, 시멘트 면과 같은 소지의 움푹 패인곳이나 실크랙 같은 작은 크랙 부분에 고여 도막이 형성 되어도 강도 및 부착성이 우수(패인 곳에 하도, 메꿈 처리가 한번에 가능)하다. It is excellent in strength and adhesion even when the coating film is formed on a small crack such as a crack or a crack in a substrate such as a concrete surface or a cement surface with a high solid paint.
즉, 본 발명은 고 고형분의 무용제 하도도료로 총휘발성화합물의 함유량이 극히 작아 실내 공기질에 대한 영향이 적고, 그 물성이 향상된 하도(프라이마) 조성물을 제공할 수 있다.That is, the present invention can provide a primer composition in which the content of total volatile compounds is extremely small due to a high-solids non-solvent-based primer coating, so that the effect on indoor air quality is small and the physical properties thereof are improved.
