본 발명은 공기중의 오염 물질을 제거하기 위해 공기 청정제로 사용되는 이산화티타늄을 테프론 필름에 고정시키는 방법을 제공하기 위한 것이다.The present invention is to provide a method of fixing titanium dioxide to a Teflon film used as an air freshener to remove contaminants in the air.
즉, 본 발명은 이소프로필알콜과 물의 혼합 용액에 티타늄 테트라이소프로퍼옥시드와 이소프로필알콜을 적가하여 혼합 용액을 제조하거나, 에탄올 또는 프로판올과 티타늄 테트라이소프로퍼옥시드 또는 티타늄 테트라부톡시드의 혼합 용액에 염산을 첨가한 에탄올을 혼합하여 혼합 용액을 제조하고, 여기에 테프론 필름을 담근 후, 상기 테프론 필름을 건조시켜서 되는 공기 청정제로 사용되는 이산화티타늄을 테프론 필름에 고정시키는 방법인 것이다.That is, according to the present invention, titanium tetraisoproperoxide and isopropyl alcohol are added dropwise to a mixed solution of isopropyl alcohol and water, or a mixed solution of ethanol or propanol and titanium tetraisopropoxide or titanium tetrabutoxide is prepared.

Description
본 발명은 공기 청정제로 사용되는 이산화티타늄을 고정시키는 방법에 관한 것이다. 더욱 상세하게는, 공기의 오염 물질을 광촉매 반응에 의해 제거하기 위해 이산화티타늄을 테프론 필름에 고정시키는 방법에 관한 것이다.The present invention relates to a method for fixing titanium dioxide used as an air freshener. More specifically, the present invention relates to a method of fixing titanium dioxide to a Teflon film to remove air pollutants by photocatalytic reaction.
현재 날로 심각해져가는 대기오염 문제 중, 인간의 생활, 특히 건강과 밀접한 관계를 가지고 있는 저 농도의 실내공기 오염의 문제는 지금까지 소홀히 다루어져왔고, 발생원에서의 처리 대책이 수립되어 있지 않은 상태에서 실내 생활자에게 육체적 및 정신적 피해가 우려된다. 일반적인 대기 환경 중 유기 오염물, 악취 및 세균에 대한 피해의 정도는 명확히 밝혀진 바 없으나, 최근 실내 공기 청정기, 청정제 및 살균제의 소비가 늘어나고 있는 추세이다. 그러나, 이들 약품의 사용이 실내공기중의 미량 유기 오염물질, 악취 및 세균 등을 완벽하게 처리할 수 있는 것은 아니고 처리 기기의 설치와 설치장소 및 비용 등의 측면에서도 바람직한 것은 아니다.Among the problems of air pollution, which are becoming more serious today, the problem of low concentration of indoor air pollution, which has a close relationship with human life, especially health, has been neglected until now, and indoors have not been established. There is concern about physical and mental damage to the living person. The degree of damage to organic pollutants, odors and bacteria in the general air environment is not clear, but the consumption of indoor air purifiers, detergents and fungicides has recently increased. However, the use of these chemicals is not able to completely treat trace organic contaminants, odors and bacteria in the indoor air, and is not preferable in terms of installation, installation place and cost of processing equipment.
일반적으로 반도체 재료에 빛을 조사하면 광촉매 작용을 일으키는 것이 이미알려져 있다. 예를 들면, 이산화티타늄 전극과 백금 전극을 조합시킨 광전기 화학 셀에서는 전해질 수용액 중에서 이산화티타늄 전극에 빛을 조사함으로써 이산화티타늄 전극에서 산소가 발생하고, 백금 전극에서 수소가 발생한다. 이는 광전기 화학 효과에 의한 물의 분해에 의한 것이다.In general, it is known that irradiation of light onto a semiconductor material causes a photocatalytic action. For example, in a photoelectrochemical cell in which a titanium dioxide electrode and a platinum electrode are combined, oxygen is generated at the titanium dioxide electrode by irradiating light to the titanium dioxide electrode in an aqueous electrolyte solution, and hydrogen is generated at the platinum electrode. This is due to the decomposition of water by the photoelectrochemical effect.
가정과 사무실에서 발생하는 악취는 질소화합물(예를들면, 암모니아, 아민류, 인돌류 및 스카톨 등), 황화합물(예를들면, 황화수소, 메틸머캡탄, 황화메틸 및 이황화메틸 이황화디메틸 등), 알데히드류(예를들면, 포름알데히드, 아세트알데히드 등), 케톤류(예를들면, 아세톤 등), 알콜류(예를들면, 메탄올, 에탄올 등), 지방산 및 방향족 화합물 등의 매우 다양한 성분으로 이루어진다.Odors that occur in homes and offices include nitrogen compounds (e.g., ammonia, amines, indole and skathol), sulfur compounds (e.g., hydrogen sulfide, methylmercaptan, methyl sulfide and methyl disulfide dimethyl), aldehydes (E.g., formaldehyde, acetaldehyde, etc.), ketones (e.g., acetone, etc.), alcohols (e.g., methanol, ethanol, etc.), fatty acids, and aromatic compounds.
이처럼 이산화티타늄은 매우 강한 광촉매 작용을 나타내는데 이러한 반응성을 이용하여 태양 에너지의 화학 에너지 혹은 전기 에너지로의 변환, 유기 합성, 배수 처리에서의 살균 및 냄새 제거 등에 응용할 수 있다.As such, titanium dioxide exhibits a very strong photocatalytic action and can be used to convert solar energy into chemical or electrical energy, organic synthesis, sterilization and odor removal in wastewater treatment.
종래에는 이러한 악취 물질을 탈취하기 위해 국소적으로 탈취하는 방법과 탈취 장치를 송풍기와 연결하여 보다 넓은 공간을 탈취하는 방법이 널리 사용되었다.Conventionally, in order to deodorize such malodorous substances, a method of locally deodorizing and a method of deodorizing a larger space by connecting a deodorizer to a blower have been widely used.
상기 국소적 탈취법으로는 약품을 악취 성분과 화학적으로 반응시키는 방법과 방향제를 이용하여 단지 악취를 느끼지 못하도록 하는 방법이 널리 사용되었다. 보다 넓은 공간을 탈취하는 방법으로는 활성탄과 제올라이트 등의 흡착제를 송풍기와 조합 이용하여 악취 성분을 흡착시켜 제거하는 방법이 주로 사용되었다.As the local deodorizing method, a method of chemically reacting a drug with a malodorous component and a method of preventing a smell simply by using a fragrance are widely used. As a method of deodorizing a wider space, a method of adsorbing and removing malodorous components by using an adsorbent such as activated carbon and zeolite in combination with a blower has been mainly used.
그러나, 약품을 이용한 화학 반응 방법이나 방향제의 사용은 각각 반응이나 사용 후 다시 재생하여 사용하기 어려운 단점이 있다. 또한, 흡착제의 경우도 흡착 용량이 포화되면 탈취 성능이 현저히 저하되어 흡착제를 다시 재생하여 사용하던가 또는 새로운 흡착제로 교환해 주어야 한다.However, the chemical reaction method or the use of a fragrance using a chemical has a disadvantage in that it is difficult to regenerate and react after each reaction or use. In addition, in the case of the adsorbent, when the adsorption capacity is saturated, the deodorizing performance is significantly lowered, and the adsorbent must be regenerated and used again or replaced with a new adsorbent.
그러나, 광화학 반응을 이용한 탈취 방법은 광촉매의 수명이 거의 영구적이며 그 효과도 매우 뛰어난 점을 고려할 때 종래의 탈취 방법과는 달리 악취 물질을 효과적으로 탈취하면서 장기간 그 성능을 유지할 수 있는 탈취 방법이 될 수 있다.However, the deodorization method using the photochemical reaction can be a deodorization method that can maintain its performance for a long time while effectively deodorizing the odorous substance unlike the conventional deodorization method in consideration of the fact that the life of the photocatalyst is almost permanent and its effect is also very excellent. have.
