Description
본 발명의 기술 분야는 광촉매 적용 건축자재 제조 방법 및 이에 의해 제조된 광촉매 적용 건축자재에 관한 것으로, 특히 열처리 및 아연 도핑된 이산화티탄 광촉매를 건축자재의 표면에 함침시켜 고성능 저비용의 광촉매 적용 건축자재를 제조하도록 구현한 광촉매 적용 건축자재 제조 방법 및 이에 의해 제조된 광촉매 적용 건축자재에 관한 것이다.The technical field of the present invention relates to a method for manufacturing a photocatalyst-applied building material and a photocatalyst-applied building material manufactured thereby. In particular, heat-treated and zinc-doped titanium dioxide photocatalysts are impregnated into the surface of the building material to produce high-performance, low-cost photocatalyst-applied building materials. It relates to a method for manufacturing a photocatalyst-applied building material implemented to manufacture and a photocatalyst-applied building material manufactured thereby.
건축자재는, 흡음 및 진동 흡수 기능뿐만 아니라, 다른 부가적인 기능을 가져야 한다. 이러한 부가적인 기능은 사용 공간의 효율성을 위해서 요구되는데, 예를 들어 항균, 소취, 난연 및 새집 증후군의 원인이 되는 유해 가스 발생 방지를 포함한다. 건축자재에 추가되는 이와 같은 기능들은 새로운 건축자재의 개발과 함께 필수적인 기능이 되어 가고 있다.In addition to sound absorbing and vibration absorbing functions, building materials must have other additional functions. These additional functions are required for efficiency of use space, and include, for example, antibacterial, deodorizing, flame retardant, and prevention of noxious gas that causes sick house syndrome. Such functions added to building materials are becoming essential functions along with the development of new building materials.
한편, 이산화티탄은 광촉매들 중에서 제조하기 쉽고 안정하여 가장 많이 사용되는 광촉매이다. 광촉매는 빛(자외선)을 쐬어주게 되면 공기 중의 유기화합물을 분해하는 촉매이다. 이산화티탄에 태양이나 형광등 등의 자외선을 쐬어주게 되면, 산화, 환원 반응에 의해 수산화이온을 산화하고 과산화수소(옥시풀), 염소나 오존보다도 강력한 산화력을 갖는 OH 래디컬을 발생한다. OH 래디컬은 강력한 산화력으로 유해 물질인 배기가스 NO, SO로부터 포름알데히드나 담배와 같은 고약한 냄새가 나는 성분이 아세트알데히드 암모니아 등의 유기물질의 분자 결합을 분해 제거한다.On the other hand, titanium dioxide is the most widely used photocatalyst because it is easy to prepare and stable among photocatalysts. A photocatalyst is a catalyst that decomposes organic compounds in the air when exposed to light (ultraviolet rays). When titanium dioxide is exposed to ultraviolet rays such as sunlight or fluorescent lamps, it oxidizes hydroxide ions through oxidation and reduction reactions and generates OH radicals that have stronger oxidizing power than hydrogen peroxide (oxypool), chlorine, or ozone. With its strong oxidizing power, OH radicals decompose and remove the molecular bonds of organic substances such as acetaldehyde, ammonia, and other nasty smelling substances such as formaldehyde and cigarettes from harmful substances such as exhaust gas NO and SO.
이산화티탄에 자외선이 쐬어주게 되면, 이산화티탄이 반응하고, 그 이산화티탄은 공기 중의 물과 산소를 분해하며, 이산화티탄의 표면에 활성산소 OH(OH 래디컬)와 O2(슈퍼 산화물 이온)를 생성하여 공기 중의 세균, 미생물을 분해한다. 이러한 이산화티탄이 광촉매로서 기능하기 위해서는, 아나타제형(anatase type) 등의 결정성을 가져야한다. 따라서 티타늄 출발물질로부터 가수분해와 축합중합 반응을 통해 비정질의 이산화티탄을 생성하였을 경우, 이를 아나타제형 이산화티탄으로 전환시키기 위해 고온 열처리 과정인 소성 공정을 필요로 한다. 이때, 소성 온도는 높은 고온을 필요로 한다.When titanium dioxide is irradiated with ultraviolet rays, titanium dioxide reacts, and the titanium dioxide decomposes water and oxygen in the air, generating active oxygen OH (OH radical) and O2 (super oxide ion) on the surface of titanium dioxide. Decomposes bacteria and microorganisms in the air. In order for such titanium dioxide to function as a photocatalyst, it must have crystallinity such as anatase type. Therefore, when amorphous titanium dioxide is produced from a titanium starting material through hydrolysis and condensation polymerization, a high-temperature heat treatment process, such as a sintering process, is required to convert it into anatase-type titanium dioxide. At this time, the firing temperature requires a high temperature.
이산화티탄을 이용하여 공장에서 직접 광촉매 막이 도포된 건축자재는, 지금까지 여러 종류 개발되어 왔지만, 운반이나 부착 시 코팅된 피막이 손상될 위험이 있었다. 또한, 미리 코팅된 건축자재의 경우에는, 이음새에는 도포되지 않은 부분이 상당량 남아 있게 되어 그 효과가 의심스러웠다.Several types of building materials to which a photocatalytic film is directly applied in a factory using titanium dioxide have been developed so far, but there is a risk of damaging the coated film during transportation or attachment. In addition, in the case of pre-coated building materials, a significant amount of uncoated parts remained at the seams, making the effect questionable.

However, the fact that the existing photocatalyst is expensive in terms of cost acts as a disadvantage in terms of economy, and when such an expensive photocatalyst with low photoactivity is used for building materials, its reactivity is low and economically inefficient, so it is difficult to find a market for the related market. It is difficult to expand, the manufacturing process is complicated, mass production is not easy, and it is difficult to apply easily.

이제 본 발명의 실시 예에 따른 광촉매 적용 건축자재 제조 방법 및 이에 의해 제조된 광촉매 적용 건축자재에 대하여 도면을 참고로 하여 상세하게 설명한다.Now, a method for manufacturing a photocatalyst-applied building material according to an embodiment of the present invention and a photocatalyst-applied building material manufactured thereby will be described in detail with reference to the accompanying drawings.
도 1은 본 발명의 실시 예에 따른 광촉매 적용 건축자재 제조 방법을 제1예로 설명하는 도면이다.1 is a view illustrating a method of manufacturing a building material using a photocatalyst according to an embodiment of the present invention as a first example.
도 1을 참조하면, 광촉매 적용 건축자재 제조 방법은, 액상화단계(S110), 표면처리단계(S120), 함침단계(S130)를 포함한다.Referring to FIG. 1 , the photocatalyst applied building material manufacturing method includes a liquefaction step (S110), a surface treatment step (S120), and an impregnation step (S130).
액상화단계(S110)는, 액상화기나 혼합기 등을 이용하여 열처리 및 아연 도핑된 이산화티탄(TiO2) 광촉매를 액상화해 준다.In the liquefaction step (S110), the heat-treated and zinc-doped titanium dioxide (TiO 2 ) photocatalyst is liquefied using a liquefier or a mixer.
일 실시 예에서, 액상화단계(S110)는, 액상의 광촉매 제조 시에, 열처리 및 아연 도핑된 이산화티탄 광촉매를 분말화시킨 후에, 증류수 100중량부에 대하여 분말 광촉매를 10 ~ 60 중량%로 혼합하여 광촉매 액상을 만들어 줄 수 있는데, 이때 1 중량% 미만으로 혼합 시에는 함침단계(S130)에서 광촉매가 충분히 함침되는 시간이 길어져 작업의 효율성이 떨어질 수 있으며, 60 중량% 이상으로 혼합 시에는 함침단계(S130)에서 광촉매가 충분히 함침되지 않을 수 있어 효능이 떨어질 수 있기 때문이다.In one embodiment, the liquefaction step (S110) is performed by mixing 10 to 60% by weight of the powdered photocatalyst with respect to 100 parts by weight of distilled water after heat-treating and pulverizing the zinc-doped titanium dioxide photocatalyst when preparing the liquid photocatalyst. The photocatalyst liquid phase can be made. At this time, when mixed at less than 1% by weight, the time for the photocatalyst to be sufficiently impregnated in the impregnation step (S130) may decrease, and the efficiency of the work may decrease, and when mixed at 60% by weight or more, the impregnation step ( This is because the photocatalyst may not be sufficiently impregnated in S130) and the efficacy may be reduced.
일 실시 예에서, 액상화단계(S110)는, 열처리 및 아연 도핑된 이산화티탄 광촉매를 나노 입자화한 후에 조촉매와 염기성 첨가제를 첨가하여 액상화할 수 있다. 이때, 분쇄기나 나노입자화기 등을 이용하여 산화티타늄을 330㎡/g 이상의 표면적과 10nm 내지 60nm의 입자 크기를 가지도록 나노 입자화시킬 수 있다.In one embodiment, in the liquefaction step (S110), after heat treatment and conversion of the zinc-doped titanium dioxide photocatalyst into nanoparticles, a cocatalyst and a basic additive may be added to liquefy the photocatalyst. At this time, the titanium oxide may be nano-particled to have a surface area of 330 m 2 /g or more and a particle size of 10 nm to 60 nm using a grinder or a nano-particle machine.
일 실시 예에서, 액상화단계(S110)는, 산화티타늄을 나노 입자화함으로써, 세기가 약한 자외선 파장을 나타내는 광원을 사용해도 다량의 과산소 라디칼을 생성하여, 유기물의 분해 능력이 우수하고, 건축물의 외벽, 내벽, 타일 등에 적용이 가능하며, 환경 변화에도 지속적인 내구성 및 안정성을 가지며, 반영구적인 특성을 가지게 된다.In one embodiment, in the liquefaction step (S110), by converting titanium oxide into nanoparticles, a large amount of peroxygen radicals are generated even when using a light source showing an ultraviolet wavelength with low intensity, and the decomposition ability of organic matter is excellent, and the building It can be applied to exterior walls, interior walls, tiles, etc., has continuous durability and stability even in environmental changes, and has semi-permanent characteristics.
