Description
본 발명은 광촉매 코팅피막자재의 제조 방법 및 장치에 관한 것으로, 더욱 상세하게는 광촉매의 손실을 최소화하고 피막 밀도 및 밀착성을 높이며 광촉매가 활성화되도록 함으로써 광촉매의 기능 향상을 제고할 수 있도록 함과 동시에 장기간의 광촉매 효과를 유지할 수 있도록 한 광촉매 코팅피막자재의 제조 방법 및 장치에 관한 것이다.The present invention relates to a method and apparatus for manufacturing a photocatalyst coating material, and more particularly, to improve the function of the photocatalyst by improving the photocatalyst function by minimizing the loss of the photocatalyst, increasing the film density and adhesion, and activating the photocatalyst. The present invention relates to a method and an apparatus for producing a photocatalyst coating film material capable of maintaining the photocatalytic effect.
일반적으로 광촉매(photocatalyst)는 빛(Photo)과 촉매(catalyst)의 합성어로 빛을 이용한 촉매라 할 수 있으며 빛을 에너지원으로 촉매 반응을 진행시키는 물질을 지칭하는데, 그 자신은 변화하지 않으면서 화학반응을 촉진시키는 효과가 있는 물질이다.In general, photocatalyst is a compound word of photo and catalyst, which is a catalyst using light, and refers to a material that proceeds catalyzed light as an energy source. It is a substance that has an effect of accelerating the reaction.
광촉매로는 반도체성 금속 산화물이나 황 화합물이 이용되는데, 반도체는 일정한 영역의 에너지가 가해지면 전자가 가전자대(valence band)에서 전도대(conduction band)로 여기 된다. 즉, 전도대에는 전자(electron)들이 형성되고 가전자대에는 정공(electron hole)이 형성된다. 이렇게 형성된 전자와 정공은 각각 산화/환원 반응에 참여하게 된다.As the photocatalyst, a semiconducting metal oxide or a sulfur compound is used. In the semiconductor, when a certain region of energy is applied, electrons are excited from the valence band to the conduction band. In other words, electrons are formed in the conduction band and holes are formed in the valence band. The electrons and holes thus formed participate in the oxidation / reduction reaction, respectively.
이러한 광촉매는 그 기능이 다양하여 적용분야가 급속히 확대되고 있는데, 광촉매의 주요효과를 살펴보면 다음과 같다.These photocatalysts have various functions and are rapidly expanding their application fields. The main effects of the photocatalyst are as follows.
첫째, 자정효과(self-cleaning)가 있다. 광촉매는 유기물을 분해하고 먼지나 기름 등 각종 오염물을 용이하게 제거하므로 청결상태를 유지할 수 있게 한다.First, there is self-cleaning. Photocatalyst can keep organic state by decomposing organic matter and easily removing various contaminants such as dust and oil.
둘째, 냄새를 제거한다. 실내 및 밀폐된 공간에서 발생하는 각종 미생물균 및 악취를 분해하여 준다. 광촉매는 단순한 냄새 흡수가 아니라 담배의 니코친, 곰팡이, 암모니아 계통의 냄새 원인을 분자 레벨로 분해하므로 근본적인 냄새를 제거한다.Second, remove the smell. Decomposes various microorganisms and odors generated in indoor and enclosed spaces. Photocatalysts eliminate fundamental odors by breaking down the odor causes of nicotine, mold and ammonia from tobacco at the molecular level, rather than simply absorbing odors.
셋째, 살균작용을 한다. 광촉매는 각종 병원균과 박테리아 등 모든 대상물질을 산화시켜 살균되게 한다.Third, sterilization. The photocatalyst oxidizes and sterilizes all target substances such as various pathogens and bacteria.
넷째, 오염방지작용을 한다. 광촉매는 축산폐수, 오수, 공장폐수의 BOD, 색도 및 난분해성 오염물질 및 환경호르몬 등을 완벽히 제거하여준다.Fourth, to prevent pollution. Photocatalysts completely remove livestock wastewater, sewage, factory wastewater BOD, chromatic and hardly degradable contaminants, and environmental hormones.
한편, 이와 같은 광촉매의 다양한 기능 및 효과에 의하여 광촉매의 적용범위는 급속도로 확대 적용되어가고 있는데, 종래의 기술에 의하면 광촉매의 응용시 광촉매의 피막밀도 및 밀착성이 떨어지거나 활성화가 제대로 이루어지지 못하여 오히려 광촉매의 기능 및 효과를 저하시키는 요인으로 작용할 뿐만 아니라 장기간의 효과유지가 어려워 반영구적으로 사용할 수 없는 문제점이 있으며, 제작단가가 높아 광범위한 적용을 어렵게 하는 문제점이 있었다.On the other hand, due to the various functions and effects of the photocatalyst, the application range of the photocatalyst is rapidly expanding and applied. According to the related art, the film density and adhesiveness of the photocatalyst are decreased or activation is not properly performed when the photocatalyst is applied. Not only does it act as a factor to deteriorate the function and effect of the photocatalyst, there is a problem that can not be used semi-permanently because it is difficult to maintain the long-term effect, there is a problem that the high production cost makes it difficult to apply a wide range.
본 발명은 상기와 같은 문제점을 해결하기 위하여 제안된 것으로서, 그 목적으로 하는 바는 광촉매의 손실을 최소화하고 피막 밀도 및 밀착성을 높일 수 있도록 함과 더불어 장기간의 광촉매 효과를 유지할 수 있도록 하며 제작단가를 낮출수 있도록 한 광촉매 코팅피막자재의 제조방법을 제공하는데 있다.The present invention has been proposed to solve the above problems, and its purpose is to minimize the loss of the photocatalyst, to increase the film density and adhesion, and to maintain the long-term photocatalytic effect and to increase the manufacturing cost. It is to provide a method for producing a photocatalyst coating film material to be lowered.
특히, 본 발명은 자외선의 빛에너지 조사에 의하여 광촉매의 활성화를 촉진시킬 수 있도록 한 광촉매 코팅피막자재의 제조방법을 제공하는데 있다.In particular, the present invention is to provide a method for producing a photocatalyst coated film material to facilitate the activation of the photocatalyst by irradiation of light energy of ultraviolet light.
본 발명의 다른 목적은 광촉매의 손실을 최소화하고 피막 밀도 및 밀착성을 높일 수 있으며 광촉매의 활성화를 촉진시킬 수 있도록 한 광촉매 코팅피막자재의 제조장치를 제공하는데 있다.Another object of the present invention is to provide an apparatus for producing a photocatalyst coating film material which can minimize the loss of the photocatalyst, increase the film density and adhesion, and promote the activation of the photocatalyst.
