Description

티타네이트 나노튜브 막을 이용한 금속 필터 제조방법{METHOD FOR MANUFACTURING METAL FILTER USING TITANATE NANOTUBE FILM}METHODS FOR MANUFACTURING METAL FILTER USING TITANATE NANOTUBE FILM}

본 발명은 티타네이트 나노튜브(titanate nanotube, TiNT) 막을 이용하여 금속 와이어(Metal wire)를 필터 미디어로 사용하는 고성능 금속 필터 제조 방법에 관한 것으로, 더욱 상세하게는 반복적 자기조립법(Layer-by-layer self-assembling)을 이용하여 티타네이트 나노튜브의 막을 금속 와이어에 코팅하여 금속 필터의 기공 크기를 줄여서 입자의 크기를 0.3 ㎛ 입자까지 포집할 수 있는 고성능 금속 필터의 제조방법에 관한 것이다. The present invention relates to a method of manufacturing a high performance metal filter using a metal wire as a filter medium using a titanate nanotube (TiNT) membrane, and more particularly, to repeat self-assembly (Layer-by-layer). The present invention relates to a method of manufacturing a high performance metal filter capable of capturing particle size up to 0.3 μm particles by reducing the pore size of the metal filter by coating the membrane of the titanate nanotube on the metal wire using self-assembling.

대기 중에 부유하고 있는 입자들은 육안으로 볼 수 있는 것과 볼 수 없는 아주 작은 크기의 것이 있으며, 인체에 해로운 미생물, 방사능 입자, 담배연기, 중금속 및 작업 분진으로부터 자연현상인 안개, 아지랑이 및 이슬비 등의 약 0.001 ㎛크기에서 수백 ㎛ 크기로 구성된다. Particles suspended in the atmosphere can be seen with the naked eye and very small in size, and can be found in medicines such as fog, haze and drizzle, which are natural phenomena from microorganisms, radioactive particles, tobacco smoke, heavy metals and working dust, which are harmful to the human body. It is composed of 0.001 μm in size and several hundred μm in size.

그러나, 현재 환경 위생적으로나 과학기술적 목적으로 문제의 대상이 되고 있는 입자들의 크기는 직경이 약 0.01 ㎛ 에서 10 ㎛ 정도이며, 이러한 크기의 입자들을 가장 효과적으로 제거 할 수 있는 방법은 고성능 필터의 사용이다.However, the size of particles that are currently problematic for environmental and hygienic purposes is about 0.01 to 10 μm in diameter, and the most effective method of removing particles of this size is the use of high performance filters.

기존의 고성능 필터는 주로 유리섬유(Glass fiber)나 고분자 등을 필터 미디어로 사용하고 있으나, 고온/고압에 매우 약하며 입자 상호간의 응결작용에 의해 한번 사용한 필터는 재사용이 어렵다는 단점을 가지고 있다. Conventional high-performance filters mainly use glass fibers or polymers as filter media, but they are very weak at high temperature / high pressure and have a disadvantage in that once used filters are difficult to reuse due to coagulation between particles.

또한, 유리 섬유 입자로 구성된 필터의 경우, 강도가 약하여 고압 송풍 시, 유리섬유 분진이 2차 오염을 발생하거나 손상의 우려가 있고, 대안으로 사용되는 고분자 소재 필터는 고온에 사용이 어려우며 산이나 알칼리 등의 화학 약품에 쉽게 부식되는 단점이 있다.In addition, in the case of the filter composed of glass fiber particles, the strength of the glass fiber is a secondary pollution or damage may occur during high pressure blowing, alternatively, the polymer filter used alternatively is difficult to use at high temperatures, acid or alkali There is a disadvantage that it is easily corroded to chemicals such as.

금속 와이어를 필터 미디어로 사용하는 고성능 필터는 1,000℃, 5bar 이상의 고온, 고압에서 필터로서의 기능 수행이 가능하며, 금속의 강한 살균성 때문에 기존 필터에 비해 대기 중 유해미생물의 제거가 효율적이고, 사용 후 필터 폐기 시, 전량 회수가 가능하여 재사용할 수 있는 장점을 보유하고 있는 친환경 기술이다.High-performance filter using metal wire as filter media can perform the function as a filter at high temperature and high pressure of 1,000 ℃, 5bar or higher, and it is more efficient to remove harmful microorganisms in the air than the existing filter due to strong sterilization of metal, and filter after use It is an eco-friendly technology that has the advantage of being reusable as it can be recovered in its entirety when discarded.

금속 소재의 필터는 일부 시중에 유통되고 있으나 극히 단순한 프리필터(Pre filter) 수준이고, 금속 분말을 압착 소결하여 필터를 제작하려는 시도가 있으나, 금속 와이어를 사용할 경우, 두께로 인한 나노 기공층 확보가 어려워 금속 소재가 이용된 고성능 필터 개발이 어려운 실정이다. Although metal filters are commercially available in some markets, they are extremely simple pre-filters, and there are attempts to fabricate filters by compressing and sintering metal powder. However, when using metal wires, it is difficult to secure nano-pore layers due to thickness. It is difficult to develop high performance filters using metal materials.

한편, 티타네이트 나노튜브 제조에 관한 기술과 관련해서는, 한국공개특허 10-2005-0087021호(이하, '선행문헌')외 다수 출원 및 공개되어 있다.On the other hand, with respect to the technology for the production of titanate nanotubes, Korean Patent Application Publication No. 10-2005-0087021 (hereinafter referred to as "prior literature") and many other applications and publications.

선행문헌에 따른 티타네이트 나노튜브 제조방법은, 티타니아 화합물을 알칼리 처리로 용해시키는 공정과, 상기 용해된 화합물을 물로 세척한 후, 무기산으로 상온 ∼ 100 ℃에서 0.5 ∼ 6 시간동안 산처리 하여 숙성시키는 공정을 포함하여 이루어진다. The method for preparing titanate nanotubes according to the prior document is a step of dissolving the titania compound by alkali treatment, and washing the dissolved compound with water, followed by acid treatment with inorganic acid at room temperature to 100 ° C. for 0.5 to 6 hours to mature. Including the process.

현재 이러한 티타네이트 나노튜브는 광촉매나 태양전지에서 많이 적용하고 있으나, 금속 와이어를 미디어 사용하는 고성능 필터에는 사용을 하지 못하고 있다. At present, such titanate nanotubes are widely used in photocatalysts and solar cells, but are not used in high performance filters using metal wires as media.

Specifically, iterative self-assembly method is to place a solution of a titanate nanotube (TiNT) having a reverse charge between an aqueous polyimideimine (PEI) solution and a polydiallyldimethylammonium (PDDA) aqueous solution with a positive potential, In order to reduce the pore size of the metal filter, the film of the titanate nanotubes is repeatedly coated on the metal filter by repeated self-assembly to reduce the pore size of the metal filter.
