Description
본 발명은 건축자재사전적합제도에 의한 친환경 무용제 에폭시 라이닝 조성물 및 이를 이용한 주차장 시공 방법에 관한 것이다. 보다 구체적으로, 본 발명은 착색력이 우수하고 얇은 두께로 도막을 형성할 수 있는 무용제 에폭시 라이닝 조성물 및 이를 이용한 주차장 시공 방법에 관한 것이다.The present invention relates to an environmentally friendly solvent-free epoxy lining composition by a building material dictionary conformance system and a parking lot construction method using the same. More specifically, the present invention relates to a solvent-free epoxy lining composition capable of forming a coating film with excellent coloring power and a thin thickness and a parking lot construction method using the same.
빌딩, 상가, 주택, 아파트, 공장 등의 바닥 마감재 등에 많이 사용되고 있는 에폭시 도료는 환경을 고려하는 제품들이 각광을 받고 있다. 최근 녹색 기술을 위한 기술들은 용제를 사용하지 않는, 빠른 경화, 낮은 VOCs(휘발성 유기 화합물), 햇빛에 대한 내황변성, 내외부의 물리적 영향에도 내구성이 강한 도료를 위한 노력이 지속되고 있다. Epoxy paints, which are widely used for floor finishing materials in buildings, shopping malls, houses, apartments, factories, etc., are receiving a lot of attention due to environmental considerations. In recent years, technologies for green technology have continued to make paints that are durable without solvent, fast curing, low VOCs (volatile organic compounds), yellowing resistance to sunlight, and physical influences on the inside and outside.
국내에서는 '환경부고시 제2012-130호' 대기환경보전법 제2조 제10호에 따라 '휘발성유기화합물 지정 고시'(환경부고시 제2009-198호, 2009. 8. 28)를 개정ㆍ고시하고, 다중이용시설 또는 공동주택의 신축 개ㆍ보수를 할 때에는 건축자재가 기준을 초과하는지 여부를 사전에 확인한 후 사용하여야 하는 "건축자재 사전적합 확인제도"가 2016년부터 시행되었다. 또한, 건축자재를 제조, 수입하는 자도 건축자재를 공급할 때에는 기준 초과 여부를 확인받은 후에 공급하여야 한다. 이러한 환경을 위한 VOCs 규제로 도료 바닥재 등에 사용되던 유기 용매들이 무용매 또는 친환경 수용성 용매로 전환되고 있으며 소비자들도 객관적 환경 유해 성능을 비교하며 구매할 수 있다. 따라서, 관련 제조업체들은 환경 친화적인 제품의 저변을 확대하고 시장점유율을 확대하는 기회로 삼아, 앞 다투어 신기술 개발 및 기술 향상에 전력을 다하고 있다. In Korea, amendment and notification of 'Designation of Volatile Organic Compounds' (Ministry of Environment Notice No. 2009-198, Aug. 28, 2009) pursuant to Article 2, Article 10 of the Air Environment Conservation Act No. 2012-130, In 2016, a new construction materials preconfirmation system was implemented to reconstruct multi-use facilities or multi-unit housings. In addition, a person who manufactures or imports building materials shall supply the building materials after confirming whether they exceed the standard. Due to the VOCs regulation for these environments, organic solvents used for paint flooring are being converted into solvent-free or eco-friendly water-soluble solvents, and consumers can purchase them by comparing objective environmental harmful performances. As a result, related manufacturers are making great efforts to develop new technologies and improve their technologies as an opportunity to expand the base of eco-friendly products and to increase their market share.
그러나, 일반적인 에폭시는 후막형이고, 착색안료 함유량이 적으며 표면장력이 높아서 얇게 스프레이 하였을 시 은폐력(소지면에 색상을 부여하는 정도)이 나쁘고, 균일하게 소지면에 도포되지 않고 마치 기름이 묻어져 있는 면에 물이 떨어졌을 때와 같은 현상이 나타나며, 많은 양의 용제 희석제를 혼합하여 사용하여야 한다. 상기 도료 자체는 "건축자재 사전적합 확인제도"에 적합하나 이를 적용 현장 시공과정에서 많은 양의 용제ㆍ 희석제를 사용해야 하므로 법의 취지를 흐리고 있는 상태이다.However, general epoxy is thick film type, it has low coloring pigment content and high surface tension, so that when it is thinly sprayed, its concealing power is poor. The same phenomenon occurs when the water drops, and a large amount of solvent diluent must be mixed and used. The paint itself is suitable for the "confirmation of preconstruction of building materials", but it is in a state of obscurity because it requires the use of a large amount of solvents and diluents during the construction of the application site.
따라서, 위와 같은 문제점을 해결할 수 있는 도료 및 이를 이용한 주차장 시공 방법의 개발이 필요하다. Therefore, it is necessary to develop a paint that can solve the above problems and a parking lot construction method using the same.
