본 발명은 광촉매(LIGHT CATALYST)제에 분자접촉 활성이 강한 금속인 은(Ag)을 치환시켜 초 내열성 동위체조직 결정 구조로 조성하여 약0.2㎛∼1.5㎛이내로 박분하여 내항균성이 절실히 요구되는 수질개선 및 종합적인 환경분야는 물론, 의류, 고 내열성의 도자기류, 등에 적용이 용이하게 하여 밝은 곳에서 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 함은 물론 빛이 차단된 암실과 같은 어두운 곳에서도 접촉성멸균 및 살균은 물론 각종 세균과 이물질을 차례 차례 끌어들여 멸균력을 강하게 하도록 한 광촉매(LIGHT CATALYST)를 은(Ag)으로 도포되도록한 은(Ag)이 도포된 광촉매 제조방법에 관한 것이다.The present invention substitutes silver (Ag), a metal having strong molecular contact activity, into a photocatalyst to form a super heat-resistant isotope tissue crystal structure, which is divided into about 0.2 μm to 1.5 μm to improve water quality. In addition to the general environmental field, it is easy to apply to clothing, high heat-resistant ceramics, etc. and receives a wavelength of light in a bright place to generate a pair of positive holes, and various foreign substances present in the vicinity of the light catalyst. Oxidation, reduction, and reaction of bacteria, etc. cause rapid sterilization and decomposition, as well as contact sterilization and sterilization as well as sterilization by attracting various bacteria and foreign substances in turn in dark places such as dark rooms where light is blocked. The present invention relates to a photocatalyst manufacturing method coated with silver (Ag) in which a photocatalyst (LIGHT CATALYST) made to be hardened is coated with silver (Ag).
일반적으로 광에너지를 받아서 촉매작용으로 매우 적은 에너지를 받아서 고 에너지 상태로 나타내는 물질을 총칭하여 광촉매(LIGHT CATALYST)라 한다.In general, a material that receives light energy and receives very little energy through catalysis and exhibits a high energy state is collectively referred to as a photocatalyst.
이와같이 광촉매(LIGHT CATALYST)는 387㎚파장의 자외선을 받아도 근접되어있는 용존산소가 분해되면서 마이너스 전기 띤 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 사용범위를 살펴보면 물의소독,살균, 단백질 흡착후 분해, 악취제거, 각종 세균과 곰팡이균, 병원균O-157, 황색포도상구균, 유황산화세균 등의 멸균, 포도당 (글리코우스)과 음이온 계면활성계 양이온 계면활성제, 담배진, 이산화탄소분해 등에 사용된다.As such, LIGHT CATALYST decomposes dissolved oxygen, which is in close proximity even when exposed to ultraviolet rays of 387nm wavelength, to generate a pair of negatively charged electrons and positively-charged holes, and various foreign substances present near the LIGHT CATALYST. By rapidly proceeding the redox reaction, LIGHT CATALYST itself is devoted to decomposing and sterilizing foreign substances by increasing the reaction rate in a state where the activation energy of the reaction system is lowered by focusing only on the oxidizing power of the foreign substance without oxidation or reduction. The range of their use is disinfection of water, sterilization, decomposition after protein adsorption, odor removal, sterilization of various bacteria and fungi, pathogens O-157, Staphylococcus aureus, sulfur oxidizing bacteria, glucose (glycose) and anionic surfactants. It is used for cationic surfactants, tobacco dust, and carbon dioxide decomposition.
본 발명은 광촉매(LIGHT CATALYST)제에 분자접촉 활성이 강한 금속인 은(Ag)을 치환시켜 초 내열성 동위체조직 결정 구조로 조성하여 약0.2㎛∼1.5㎛ 이내로 박분하여 내항균성이 절실히 요구되는 수질개선 및 종합적인 환경분야는 물론, 의류, 고 내열성의 도자기류, 등에 적용이 용이하게 하여 밝은 곳에서 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 함은 물론 빛이 차단된 암실과 같은 어두운 곳에서도 접촉성멸균 및 살균은 물론 각종 세균과 이물질을 차례 차례 끌어들여 멸균력을 강하에 하도록 유지 되도록한 광촉매분말의 외부를 은(Ag)으로 도포하여 인체 내부에 사용이 가능하도록 함에 그 목적을 둔 것이다.According to the present invention, a silver (Ag), which is a metal having strong molecular contact activity, is substituted with a LIGHT CATALYST agent to form a super heat-resistant isotope structure crystal structure, which is about 0.2 μm to 1.5 μm. It is easy to be applied to water quality improvement and general environment field that requires antibacterial resistance as well as it is easily divided into within, and it is easy to apply to clothing, high heat resistant ceramics, etc. It oxidizes, reduces, and rapidly reacts various foreign substances and bacteria in the vicinity of LIGHT CATALYST) to sterilize and decompose, as well as contact sterilization and sterilization even in dark places such as light-blocked dark rooms. The purpose of the present invention is to apply the outside of the photocatalyst powder with silver (Ag) to keep bacteria and foreign substances in turn to maintain sterilization power.

실시예;Example;
전체중량비의 순수물 약50중량%에 질산(N03) 약3중량%를 넣고 충분히 용해시킨후 여기에 미량의 은(Ag) 약1중량%를 투입하여 약60℃로 가열하고, 다시 이산화티탄(TiO2) 약46중량%를 투입하여 서서히 교반하여서 이들이 충분히 섞이면 약60℃의 온도를 계속 유지하면서 다시 저속(RPM 100이하)으로 교반하여 순수물로 수세의 공정을 거친후, 1500℃이하의 온도로 건조하여 수분을 증발시킨후 분쇄기에서 분쇄하여 밝은 곳은 물론 빛이 차단된 암실과 같은 어두운 곳에서도 강력한 항균력을 갖는 은(Ag)이 도포된 미세분말의 광촉매를 얻게 되는 것이다.Add about 3% by weight of nitric acid (N0 3 ) to about 50% by weight of pure water in the total weight ratio, dissolve it sufficiently, add about 1% by weight of trace amount of silver (Ag), and heat it to about 60 ℃, and again, add titanium dioxide. (TiO 2 ) After adding about 46% by weight and stirring slowly, if they are sufficiently mixed, the solution is stirred at low speed (RPM 100 or less) again while maintaining the temperature of about 60 ° C, and then washed with pure water, and then the temperature is lower than 1500 ° C. After drying at a temperature to evaporate the moisture, it is pulverized in a pulverizer to obtain a photocatalyst of fine powder coated with silver (Ag) having strong antibacterial activity in a dark place such as a dark room where light is blocked as well as light.
상기한 본 발명은 광촉매(LIGHT CATALYST)제에 분자접촉 활성이 강한 금속인 은(Ag)을 치환시켜 초 내열성 동위체조직 결정 구조로 조성하여 약0.2㎛∼1.5㎛이내로 박분하여 내항균성이 절실히 요구되는 수질개선 및 종합적인 환경분야는 물론, 의류, 고 내열성의 도자기류, 등에 적용이 용이하게 하여 밝은 곳에서 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 함은 물론 빛이 차단된 암실과 같은 어두운 곳에서도 접촉성멸균 및 살균은 물론 각종 세균과 이물질을 차례 차례 끌어들여 멸균력을 강하게 하도록 한 광촉매(LIGHT CATALYST)분말을 미량의 은(Ag)으로 도포하여 인체에 적용할 수 있도록한 신규하고도 유용한 발명이다.In the present invention, silver (Ag), which is a metal having strong molecular contact activity, is replaced with a photocatalyst, and formed into a super heat-resistant isotope tissue crystal structure, which is divided into about 0.2 μm to 1.5 μm, which requires deterioration of antibacterial resistance.
