본 발명은 항균·항바이러스용 Cu-PMF 및 이의 제조방법에 관한 것으로, 상세하게는 폴리멜라민-포름알데히드 재질의 필터 표면에 코팅된 구리(Cu)를 포함하는 신규한 항균·항바이러스 물질과 폴리멜라민-포름알데히드(PMF)에 코팅하는 방법에 관한 것이다. The present invention relates to an antibacterial/antiviral Cu-PMF and a method for manufacturing the same. Specifically, the present invention relates to a novel antibacterial/antiviral material containing copper (Cu) coated on the surface of a polymelamine-formaldehyde filter and poly It relates to a method of coating on melamine-formaldehyde (PMF).
최근 코로나바이러스로 인해 전 세계적으로 감염자와 사망자가 속출하면서 대유행으로 번지는 추세로서 실내 공기질에 대한 관심이 높아지고 있다. 하지만 현재 개발된 공기청정기는 바이러스와 세균을 처리할 수 있는 특화 공정이 없는 상황으로 항균 및 항바이러스 처리가 가능한 필터 또는 장치를 보유하고 있는 청정기 개발이 절실하다. Recently, interest in indoor air quality is increasing due to the coronavirus, which is spreading into a pandemic as the number of infections and deaths continues to increase worldwide. However, currently developed air purifiers do not have a specialized process to treat viruses and bacteria, so the development of a purifier with a filter or device capable of antibacterial and antiviral treatment is urgently needed.
일반적으로 구리의 항균·항바이러스 기능은 잘 알려져 있으며, 구리에 의한 세균 및 바이러스 살처분은 두 가지 메커니즘으로 설명하고 있다. 첫째, 구리와 병원균의 직접 접촉에 의한 살균(예, 세포막이 구리이온에 의해 비극성화되면서 파괴), 둘째, 구리에 의해 생성되는 반응성이 탁월한 산화제(예, 하이드록실 라디칼)에 의한 살균 효과를 꼽을 수 있다. 하지만 구리-나노 입자(Cupper-nanoparticles, Cu-NPs) 형태의 구리는 대기 중에 노출되면 산화하여 효과가 감소하고, 입자가 뭉쳐지는 문제가 있었다. In general, the antibacterial and antiviral functions of copper are well known, and the killing of bacteria and viruses by copper is explained by two mechanisms. First, sterilization by direct contact between copper and pathogens (e.g., cell membranes are depolarized and destroyed by copper ions), and second, the sterilization effect by highly reactive oxidants (e.g., hydroxyl radicals) generated by copper. You can. However, copper in the form of copper-nanoparticles (Cu-NPs) was oxidized when exposed to the air, reducing its effectiveness and causing particles to clump together.
또한, 종래에는 공기를 정화하기 위하여 일반적으로 폴리프로필렌(Poly propylene, PP) 수지 섬유 또는 폴리에틸렌(Poly ethylene) 섬유를 이용하는 부직포 형태의 필터를 사용하였다. 하지만 이는 고온에서 취약할 뿐만 아니라 고압에서 손상이나 필터 효율 저하가 빈번하게 발생되는 문제가 있어 여전히 기술 개발이 요구되고 있는 실정이다. In addition, conventionally, non-woven filters using polypropylene (PP) resin fibers or polyethylene fibers were used to purify air. However, it is not only vulnerable at high temperatures, but also frequently experiences damage or reduced filter efficiency at high pressures, so technology development is still required.
본 발명은 안정적으로 항균·항바이러스 기능을 갖는 구리이온(Cu+2)이 기질인 폴리멜라민 포름알데히드(Polymelamine-formaldehyde, PMF)에 코팅된 항균·항바이러스 물질을 제공하는 것을 목적으로 한다. The purpose of the present invention is to provide an antibacterial and antiviral material coated on polymelamine-formaldehyde (PMF), which is a substrate of copper ions (Cu+2), which has stable antibacterial and antiviral functions.
또한, 산화되지 않아 효과가 감소되지 않는 구리-나노 입자(Cupper-nanoparticles, Cu-NPs)를 활용하여 대기 중의 병원균을 처리하기 위한 공기청정 필터를 제공하는 것을 목적으로 한다. In addition, the purpose is to provide an air purification filter for treating pathogens in the air by utilizing copper-nanoparticles (Cu-NPs), which do not oxidize and do not reduce effectiveness.
또한, 고온 및 고압에서도 안정한 필터에 구리를 코팅하여 안정적인 항균·항바이러스 성능을 갖는 필터를 제공하는 것을 목적으로 한다. In addition, the purpose is to provide a filter with stable antibacterial and antiviral performance by coating copper on a filter that is stable even at high temperature and pressure.
