항균코팅마루패널 제조방법{Manufacturing method of antibacterial coated flooring panel}Antibacterial coated flooring panel manufacturing method {Manufacturing method of antibacterial coated flooring panel}

본 발명은 목재의 마감표면에 적층되어 경화되는 항균물질을 포함하는 UV 도료층이 적층형성되고, 상기 항균 물질은 Cu이며 UV도료에 100 중량부에 대하여 Cu 가 10~20 중량부가 투입되는 항균코팅마루패널 제조방법에 관한 것이다.The present invention is an antibacterial coating in which a UV paint layer containing an antibacterial material that is laminated and cured on the finished surface of wood is laminated, and the antibacterial material is Cu, and 10 to 20 parts by weight of Cu is added with respect to 100 parts by weight of the UV paint. It relates to a method for manufacturing a floor panel.

최근에는 자신만의 공간을 꾸미기 위해 건물 내부의 인테리어에 많은 신경을 쓰고 있는 경향이 두드러지고 있다. Recently, there is a tendency to pay a lot of attention to the interior of a building to decorate their own space.

특히, 혼자 사는 1인 가구의 증가로 인해 생활공간이 점차 작아지고, 내부를 꾸밀 수 있는 여건과 기회가 증대되고 있다.In particular, as the number of single-person households living alone increases, the living space is gradually getting smaller, and the conditions and opportunities for decorating the interior are increasing.

이러한 상황에 따라, 내부 벽지, 페인트 도색, 바닥 마감재, 벽타일 등을 선택하는데 더욱 신중해지고 있으며, 생활 속의 안정감을 느끼고, 고급스러운 이미지를 연출하기 위해 다수의 사람들은 목재와 같은 친환경 소재를 선택하고 있는 추세이다.In accordance with this situation, people are becoming more careful in choosing interior wallpaper, paintwork, floor finishing materials, wall tiles, etc., and in order to feel a sense of stability in life and to create a luxurious image, many people choose eco-friendly materials such as wood and there is a trend

또한, 상기와 같은 용도로 사용되는 종래의 마루바닥재는 합판 등에 무늬목이 결합된 형태가 많이 사용되고 있는데, 이러한 마루바닥재에서 무늬목은 원목을 슬라이서를 이용하여 얇게 절삭함으로써 얇은 무늬목을 얻고, 이를 MDF, HDF, 합판, OSB 등의 판재 또는 목질 재료를 바탕으로 하는 복합 재료 등의 표면에 접합하여 형성하게 된다. In addition, conventional flooring materials used for the above purposes are often used in a form in which veneers are combined with plywood, etc. In such a flooring material, thin veneers are obtained by thinly cutting raw wood using a slicer, and these are MDF, HDF It is formed by bonding to the surface of a plate material such as plywood, OSB, or a composite material based on a wood material.

이때, 원목으로부터 슬라이스된 천연 무늬목은 시트 형태로 제작되어 상측에 도장층이 형성되고 합판 등에 결합되어 마루바닥재로 많이 사용되고 있다.At this time, natural veneer sliced from raw wood is manufactured in the form of a sheet, a coating layer is formed on the upper side, and combined with plywood, etc., and is widely used as a flooring material.

하지만, 일반적으로 다세대 주택 및 아파트 등과 같은 건물에서 건축공사를 진행할 경우, 마루마닥재에 사용되는 목재는 시공 후 내구성이 떨어져 작은 충격에도 흠집이 쉽게 발생하여 마루바닥재의 미관을 해치는 요인이 된다.However, in general, when construction is carried out in buildings such as multi-family houses and apartments, the wood used for the flooring material has poor durability after construction, and scratches easily even with a small impact, which is a factor impairing the aesthetics of the flooring material.

또한, 목재로 마루바닥재를 마감하는 경우, 건물 바닥에 특정 조치 없이 마감재를 설치하는 경우가 대부분이므로, 충격음을 완충시키지 못해 아래층에 전달됨으로써 입주자 사이에 심한 스트레스 및 분쟁요인으로 작용하게 된다.In addition, in the case of finishing the flooring with wood, since the finishing material is installed on the floor of the building without any specific measures, the impact sound cannot be buffered and is transmitted to the lower floor, thereby acting as a factor of severe stress and disputes among the occupants.

더하여, 목재를 사용한 마루바닥재는 나무의 부식 및 부패를 방지하기 위해 처리하는 과정에서 사용되는 화학물질에는 중금속 및 발암성분을 함유하고 있어 환기가 원활치 않은 공간에서 장기간 노출될 경우 사용자의 건강을 해칠 우려가 발생하게 된다.In addition, wood flooring contains heavy metals and carcinogens in the chemicals used in the process to prevent corrosion and decay of wood, so long-term exposure in a poorly ventilated space may harm the health of users. will occur
