이와같은 광촉매(LIGHT CATALYST)는 387㎚파장의 자외선을 받아도 근접되어 있는 용존산소가 분해되면서 마이너스 전기를띤 전자와 플러스 전기를띤 정공이 한쌍으로 생성하여 광촉매(LIGHT CATALYST) 부근에 존재하는 각종 이물질들과 산화 환원 반응을 급격하게 진행시켜 광촉매(LIGHT CATALYST) 자신은 산화나 환원이 일어나지 않으면서이물질의 산화력에만 전념하여 가능한 반응계의 활성화 에너지를 낮추어진 상태에서 반응속도를 높여 이물질들을 분해 및 멸균시키는 것으로, 이들의 사용사용범위를 살펴보면 물의소독,살균, 단백질 흡착후 분해, 악취제거, 각종세균과 곰팡이균, 병원균O-157, 황색포도상구균, 유황산화세균 등의 멸균, 포도당(글리코우스)과 음이온 계면활성제 양이온 계면활성제, 담배진, 이산화탄소분해 등에 사용된다,Such photocatalysts generate a pair of negatively charged electrons and positively-charged holes as the dissolved oxygen decomposes, even when exposed to 387nm wavelength ultraviolet light, and causes various foreign substances present near the photocatalyst. The photocatalyst itself dedicates only to the oxidizing power of the substance without oxidation or reduction, and decomposes and sterilizes the substance by increasing the reaction rate in a state where the activation energy of the reaction system is lowered.

상기와같이 이산화티탄(TiO2)에 에칠알콜(C2H5OM)이 묻어있는 현탁상태가 된 상태에서 이들의 약 10%가 되는량의 프로필알콜(CH3CH2CH2OH)을 서서히 첨가 시키면서 교반한 다음 약3배의 증류수를 넣고 약20분동안 고속회전(3000RPM정도)으로 교반하여 백색침전물을 얻는다,As described above, in the suspended state in which ethanol (C 2 H 5 OM) is embedded in titanium dioxide (TiO 2 ), about 10% of propyl alcohol (CH 3 CH 2 CH 2 OH) is gradually added. After stirring with addition of distilled water of about 3 times and stirred for about 20 minutes at high speed (about 3000RPM) to obtain a white precipitate,
상기와같은 상태에서 질산(HNo3)을 0.2∼0.3% 첨가하여 내부온도를 85℃로 유지하면서 다시 3000RPM이상의 고속회전으로 8시간 이상을 교반하여 프로필알콜과 에칠알콜을 증발시키고 입자의 크기가 30㎚정도인 졸(Sol)상태의 광촉매(LIGHT CATALYST)를 얻는다.In the above state, nitric acid (HNo 3 ) is added in an amount of 0.2 to 0.3%, and the internal temperature is maintained at 85 ° C., and the mixture is stirred for 8 hours or more at a high speed rotation of 3000 RPM or more to evaporate propyl alcohol and ethyl alcohol and the particle size is 30. A photocatalyst (LIGHT CATALYST) in a sol state of about nm is obtained.
이와같은 졸(Sol)상태로 얻어진 광촉매(LIGHT CATALYST)에 함유되어 있는 수분을 증발시켜 완전히 제거하면 미세분말화된 광촉매(LIGHT CATALYST) 파우더를 얻게되며, 사용 용도에 따라 상기 광촉매(LIGHT CATALYST) 파우더에 유성용제를 첨가하면 유성타입의 광촉매(LIGHT CATALYST)가 되는 것이다.If the moisture contained in the photocatalyst (LIGHT CATALYST) obtained in such a sol state is evaporated and completely removed, a fine powdered photocatalyst (LIGHT CATALYST) powder is obtained, and the photocatalyst powder is used depending on the intended use. When an oily solvent is added to it, it becomes an oil type photocatalyst (LIGHT CATALYST).
상기한 본 발명은 광촉매(LIGHT CATALYST)제에 아파타이트(무기광물)와 분자접촉 활성이 강한 금속 등을 치환시켜 초 내열성 동위체조직 결정 구조로 조성하여 0.3μ∼1.5μ 이내로 박분하여 내항균성이 절실히 요구되는 수질개선 및 종합적인 환경분야는 물론, 의류, 고 내열성의 도자기류, 등에 적용이 용이하게 하여 빛의 파장을 받아 양극의 정공이 쌍 생성하여 광촉매(LIGHT CATALYST)의 부근에 존재하는 각종 이물질 및 세균류 등을 산화, 환원, 반응을 급격하게 일으키게 되어 살균 및 분해작용을 함으로서 접촉성멸균 및 살균은 물론 각종 세균과 이물질을 차례 차례 끌어들여 멸균력을 강하게 하도록한 광촉매(LIGHT CATALYST)를 얻을수 있을 뿐만 아니라 더욱이 박분화된 입자들은 매우적은 미량(0.1∼1%)만 첨가하여도 이들이 고르게 분포되어 다양한 내 기능성을 지니게되며, 유제타입의 광촉매(LIGHT CATALYST)제를 입상크기 5㎚의 졸(Sol)상태의 광촉매(LIGHT CATALYST)는 각제품에 컴파운딩(COMPOUNDING) 시키기에 매우용이하여 광범하게 적용시킬수 있으며, 특히 어떠한 반응계의 촉매작용이 가능하며, 반응계의 활성화 에너지를 낮추고 공기여과작용에 의하여 반응성이 높은 마이너스 전기를띤 전자정공을 쌍 생성하여 불안전한 상태로 전환 열역학적으로는 일어나기 어려운 반응을 가능케 하는등 신규하고도 유용한 발명이다.According to the present invention, apatite (inorganic minerals) and a metal having strong molecular contact activity are substituted for the LIGHT CATALYST, and the composition is formed into a super heat-resistant isotope tissue crystal structure, which is divided into 0.3 μ to 1.5 μ so that antibacterial resistance is desperately required. It is easy to apply to water quality improvement and general environmental field, as well as clothing, high heat resistant ceramics, etc., and creates a pair of holes of anode by receiving the wavelength of light, so that various foreign substances exist near the photocatalyst. By oxidizing, reducing, and rapidly causing bacteria, they sterilize and decompose, resulting in contact sterilization and sterilization as well as photocatalysts (LIGHT CATALYST) that draw various bacteria and foreign substances in turn to strengthen sterilization power. In addition, the thinly divided particles are evenly distributed even with the addition of very small amounts (0.1-1%), resulting in various functional resistances. LIGHT CATALYST of emulsion type LIGHT CATALYST is very easy to compound to each product and can be widely applied. It is possible to catalyze any reaction system, lower the activation energy of the reaction system, and generate a highly reactive negative electric electron hole by air filtration to convert it into an unstable state. Is also a useful invention.
