본 발명은 활성탄에 관한 것으로, 보다 상세하게는 활성탄의 기본적인 기능에 더욱 강력한 살균 및 탈취 기능을 배가시켜 바이러스, 곰팡이, 진드기 등의 균류의 서식과 악취가 발생하는 것을 원천적으로 방지할 수 있는 살균 탈취 활성탄 및 그 제조방법과 이를 이용한 살균 탈취 필터에 관한 것이다.The present invention relates to activated carbon, and more particularly, sterilization and deodorization which can prevent the generation of odors and fungi such as viruses, fungi, and mites by doubling the more powerful sterilization and deodorization functions to the basic functions of activated carbon.

이러한 활성탄(Active Carbon Fiber, ACF)은 산화 분위기 하에서 표면 산화된 탄소를 말하는데, 활성탄은 비표면적이 크고 미세 기공이 균일한 분포를 갖기 때문에 흡착 기능이 우수할 뿐만 아니라 큰 비표면적을 이용한 공기청정이나 액상여과 등의 흡착제 및 촉매 담체로 응용되고, 균일한 기공특성을 이용한 분자체로 응용되며 비교적 높은 전도도와 고 비표면적을 이용하여 전기이중층 캐패시터의 전극 등으로도 활용되고 있다.Active carbon fiber (ACF) refers to carbon that is surface oxidized in an oxidizing atmosphere. Since activated carbon has a specific surface area and a uniform distribution of fine pores, it has excellent adsorption function and air cleaning using a large specific surface area. It is applied as an adsorbent and catalyst carrier for liquid filtration, and as a molecular sieve using uniform pore characteristics. It is also used as an electrode of an electric double layer capacitor using a relatively high conductivity and a high specific surface area.

또한, 활성탄은 굉장히 우수한 평균 흡착량을 갖고 있고, 흡착속도도 매우 빠른 것으로 알려져 있다. 따라서, 이러한 활성탄을 점착시켜 만든 활성탄 필터는 주로 흡착제로서 기체나 습기를 흡수 또는 흡착하는 데 사용되며, 그 밖에 용제의 회수제와 가스의 정제용 또는 탈색제로 쓰이는 등 용도가 다양하다.In addition, activated carbon has a very good average adsorption amount and is known to have a very high adsorption rate. Therefore, activated carbon filters made by adhering activated carbon are mainly used for absorbing or adsorbing gas and moisture as adsorbents, and are used in various applications such as solvent recovery agents and gas purification or decolorizing agents.

Such filters have been developed in various forms to filter out suspended substances, harmful substances or dusts present in gas or liquid, and activated carbon filters using activated carbon for adsorption removal of organic substances are widely received.

그러나, 활성탄 필터는 주로 흡착제로서 많이 이용되고, 바이러스, 곰팡이, 진드기 등의 균류의 서식과 악취가 발생하는 것을 방지하는 살균 탈취 기능은 다소 떨어지는 문제점이 있었다.However, activated carbon filters are mainly used as adsorbents, and sterilization and deodorization functions that prevent the generation of odors and fungi such as viruses, molds, and mites have had a problem in that they are somewhat inferior.

본 발명은 상기와 같은 점을 감안하여 안출된 것으로, 활성탄의 기본적인 기능에 강력한 살균 및 탈취 기능을 배가시켜 바이러스, 곰팡이, 진드기 등의 균류의 서식과 악취가 발생하는 것을 현저히 방지할 수 있는 살균 탈취 활성탄 및 그 제조방법과 이를 이용한 살균 탈취 필터를 제공하는 데 그 목적이 있다.The present invention has been made in view of the above, sterilization and deodorization that can significantly prevent the generation and odor of fungi such as viruses, fungi, mites by doubling the powerful sterilization and deodorization function to the basic function of activated carbon It is an object of the present invention to provide an activated carbon and a method of manufacturing the same and a sterilizing deodorizing filter using the same.
