본 발명은 실리카 입자에 은나노를 화학적으로 공유결합시켜 제조한 복합소재를 이용하여 필터를 제조함으로써, 세균, 미세먼지, 바이러스에 대한 항균은 물론 VOCs, 악취물질에 대한 탈취까지 동시에 이룰 수 있어 오염된 실내공기로 인한 각종 질병 발생을 예방할 수 있는 은나노 항균, 탈취 필터를 제공하고자 하는 것을 발명의 목적으로 한다.The present invention can produce antibacterial agents against bacteria, fine dusts and viruses as well as deodorization of VOCs and odorous substances by preparing filters by using a composite material produced by chemically covalently bonding silica particles to silver nanoparticles, It is an object of the present invention to provide a silver nano antibacterial and deodorizing filter capable of preventing various diseases caused by indoor air.
상기의 목적을 달성하기 위하여,In order to achieve the above object,
본 발명은 합성섬유의 필터 메디아(Media)의 면에 은나노-실리카 복합체(SSC)를 흡착시켜 제조되는 은나노-실리카 복합체를 포함하는 고기능성 항균·탈취 필터를 제공한다.The present invention provides a highly functional antibacterial and deodorizing filter comprising a silver-nano-silica composite prepared by adsorbing a silver nanocomposite (SSC) on the surface of a filter media of synthetic fibers.
본 발명에 따른 항균·탈취 필터는 은나노-실리카 복합체(SSC)를 부직포, 신세틱 또는 유리섬유로 이루어진 메디아(Media)의 면에 흡착시켜 이루어짐으로써, 유해균을 막고 유해가스를 제거하는 데 탁월한 효과가 있다.The antibacterial / deodorization filter according to the present invention is formed by adsorbing a silver-nano-silica composite (SSC) on a surface of a medium made of a nonwoven fabric, a synthetically or a glass fiber, and thus has an excellent effect in blocking harmful bacteria and removing harmful gas have.

이하, 상기의 기술 구성에 대한 구체적인 내용을 도면과 함께 살펴보고자 한다.Hereinafter, the technical contents of the above description will be described with reference to the drawings.
도 1은 본 발명에 따라 제조된 항균, 탈취 필터의 실제 제품사진을 보인 도면으로서, 본 발명에 따른 항균·탈취 필터(1)는 필터 메디아(10)에 은나노-실리카 복합체(Silver-Silica Composite; SSC)를 흡착시켜 제조한다.FIG. 1 is a photograph of an actual product of an antibacterial and deodorizing filter manufactured according to the present invention, wherein the antibacterial /
상기 은나노-실리카 복합체(Silver-Silica Composite; SSC)는 2~3nm의 은나노 입자를 실리카 입자와 화학적 공유결합을 이루어 항균 및 유해성 VOCs 제거 기능성을 매우 강화시킨 복합체이다.The Silver-Silica Composite (SSC) is a complex in which silver nanoparticles of 2 to 3 nm are chemically covalently bonded to silica particles to greatly enhance antibacterial and toxic VOCs removal functionality.
상기 은나노-실리카 복합체는 자외선이 있어야 촉매활동을 하는 일반 광촉매와 달리 상온·무광 촉매로서, 일상 온도의 빛이 전혀 없는 조건에서도 촉매 기능을 발휘하여 항균 및 탈취기능을 갖는다. The silver nano-silica composite is a room temperature / non-matt catalyst, unlike a conventional photocatalyst which is required to have a catalytic activity with ultraviolet rays. The silver nano-silica composite exhibits a catalytic function and has an antibacterial and deodorizing function even under the condition of no light at ordinary temperature.
또한 자외선, 가시광선 등의 빗과 적외선 등의 열 에너지를 흡수하게 되는 경우 촉매 효과가 더욱 증대된다. 이러한 현상은 은나노 입자의 표면 플라스몬 공명(SPR) 현상에 의한 실리카의 활성화에 기인하며, 이를 '플라즈몬 유발 광촉매 작용(Visible-Light Driven Plasmonic hotocatalysis)'이라고 한다.In addition, when absorbing thermal energy such as combs and infrared rays such as ultraviolet rays, visible rays, etc., the catalytic effect is further increased. This phenomenon is attributed to the activation of silica by the surface plasmon resonance (SPR) phenomenon of silver nanoparticles and is called 'Visible-Light Driven Plasmonic hot-catalysis'.
은(Ag)은 항균, 살균, 방취, 전자파 차단 기능이 우수하고 650가지 이상의 세균을 죽이는 것으로 알려져 있다. 또한 나노사이즈로 분산된 은은 자외선 차단기능과 단열기능이 있으며 높은 전기 전도성으로 정전기 방지에도 탁월한 효과가 있다. 특히 은을 나노사이즈로 제어한다면 상기의 기능 중 항균력은 더욱 극대화되고 염소계열의 살균제보다 수십배 강력하고 인체에는 전혀 무해한 특성을 나타내기 때문에 안전하며 특히 은나노는 대량으로 생산이 가능하고 극소량만 첨가하여도 은 입자가 나노사이즈로 분산되어 그 효과는 매우 뛰어나 은나노 기술의 효용성은 매우 크다고 할 수 있다.Silver (Ag) is excellent in antibacterial, sterilization, deodorization, electromagnetic wave shielding and killing more than 650 bacteria. In addition, silver dispersed in nano size has ultraviolet protection function and insulation function, and it has high electric conductivity and excellent effect to prevent static electricity. Especially, if silver is controlled to nano-size, it will be more effective than other chlorine-based disinfectants, because it has a stronger anti-bacterial power than other chlorine-based disinfectants and is harmless to human body. Therefore, silver nano can be produced in large quantities. Silver nanoparticles are dispersed into nanosize, and their effect is very good. Therefore, the usefulness of nano-nanotechnology is very high.
나노사이즈로 분산된 은을 나노실버라고 하는데 나노실버의 항균메카니즘을 보면 알 수 있듯이 세균의 -SH, -COOH, -OH등과 강하게 결합해 세균의 세포막을 파괴함으로써 살균하여 인체에는 무해하며 세균을 사멸시키는데 소용되는 시간도 아주 짧을 뿐 아니라 99.9%의 살균력을 보이고 돌연변이 같은 내성을 지닌 세균이 생길 수 없다는 것이 큰 장점이라고 할 수 있다.Nanosized silver is called nano silver. As you can see from the antimicrobial mechanism of nanosilver, it binds strongly with -SH, -COOH, -OH of bacteria and destroys the bacterial cell membrane and is harmless to the human body. It is a great advantage that not only the time to be consumed is very short, but also bacteria with 99.9% sterilizing power and mutant resistance can not be produced.
본 발명에 따른 은나노-실리카 복합체를 포함하는 고기능성 항균·탈취 필터는 상기한 바와 같이, 합성섬유의 필터 메디아(Media)의 면에 은나노-실리카 복합체(SSC)를 흡착시켜 제조된다.The high-performance antibacterial / deodorization filter including the silver-nano-silica composite according to the present invention is prepared by adsorbing a silver-nano-silica composite (SSC) on the surface of a filter media of synthetic fibers as described above.
상기 합성섬유는 다양한 선택이 가능하나, 부직포, 신세틱 또는 유리섬유(Glass Fiber)를 주로 사용한다.The synthetic fibers can be selected in various ways, but nonwoven fabrics, synthetics or glass fibers are mainly used.
상기 부직포는 외관, 촉감이 다양하고 탄력성이 풍부하여 주름이 생기지 않는다. 두께를 자유로 변환 가능하고 bulky성이 좋고 가벼우며 보온성, 통기성이 크며 직물과 같이 끝부분이 풀리지 않아 재단이 자유롭다는 장점을 갖는다.The nonwoven fabric has various appearance and feel, and is rich in elasticity, so that wrinkles are not generated. It is possible to change the thickness freely, it has good bulky properties, is lightweight, has high heat retention, high air permeability, and has the advantage of free cutting because the end portion is not loosened like a fabric.
상기 부직포는 구체적인 예로서, 폴리에스터 레이온 합성 부직포를 사용한다. 상기 폴리에스터 레이온 합성 부직포는 섬유(Viscos Rayon + PET(Polyester))를 접착제를 이용하여 Web을 형성하는 침적접착법을 사용하여 생산한 부직포이다.As a specific example, the nonwoven fabric uses a polyester rayon composite nonwoven fabric. The polyester rayon composite nonwoven fabric is a nonwoven fabric produced by a deposition bonding method in which a web (Viscos Rayon + PET (Polyester)) is formed by using an adhesive.
상기 유리섬유는 유리섬유를 그대로 사용할 수도 있으나, 기계적 물성을 향상시키기 위하여 유리섬유의 전체 중량에 대해 탄소나노튜브(CNT)를 0.2~0.6wt%로 첨가한 유리섬유를 사용한다.The glass fiber may be glass fiber as it is, but glass fiber in which carbon nanotube (CNT) is added in an amount of 0.2 to 0.6 wt% with respect to the total weight of the glass fiber is used in order to improve mechanical properties.
이때, 상기 탄소나노튜브(CNT)는 벽을 이루고 있는 결합의 수에 따라서 단일벽 나노튜브(SWNT, single walled nanotube), 다중벽 나노튜브(MWNT, multi walled nanotube) 그리고 다발형 나노튜브(rope nanotube)로 구분한다.In this case, the CNTs may be formed of single walled nanotubes (SWNTs), multiwalled nanotubes (MWNTs), and rope nanotubes (MWNTs) according to the number of wall bonds. ).
상기한 바와 같이, 본 발명에 따른 은나노-실리카 복합체를 포함하는 고기능성 항균·탈취 필터는 상기 합성섬유 필터 메디아(Media)의 면에 은나노-실리카 복합체를 흡착시킴으로써 완성된다.As described above, the high-performance antibacterial and deodorization filter including the silver-nano-silica composite according to the present invention is completed by adsorbing the silver-nano-silica composite on the surface of the synthetic fiber filter media.
상기 은나노-실리카 복합체는 2~3nm의 은나노 입자를 나노 실리카 입자와 화학적 공유결합시킨 것을 사용한다.The silver-nano-silica composite is prepared by chemically covalently bonding 2 to 3 nm of silver nanoparticles with the nanosilica particles.
