Description
본 발명은 휘발성 유기화합물의 제거 및 항균성 광촉매 도료 조성물에 관한 것으로서, 더욱 상세하게는 무기바인더를 기본으로 산화 티탄계 광촉매와 항균제를 혼합하여 병원등의 공공건물이나 산업화공장, 고속도로의 차음벽, 지하 콘크리트 구조물 등에 사용되는 휘발성 유기화합물(VOC) 제거 및 항균성 광촉매 도료 조성물에 관한 것이다.The present invention relates to the removal of volatile organic compounds and antimicrobial photocatalyst coating compositions, and more particularly, to titanium dioxide-based photocatalysts and antimicrobial agents based on inorganic binders, to soundproof walls of public buildings, industrial plants, highways, and underground concrete. The present invention relates to a volatile organic compound (VOC) removal and antimicrobial photocatalyst coating composition used in structures and the like.
일반적으로 도료라 함은 방수 및 미관을 고려하여 구조물의 벽면에 도포되거나, 부식을 방지하기 위하여 철재면에 도포되는 것을 주 목적으로 하였으나, 산업이 발달하고 자동차의 사용이 증가하면서 그 목적도 점차 변화되고 있다. 즉, 대기중의 오염도가 심화됨에 따라 구조물의 외벽에 미관상 도포하던 도료에 공기청정 기능을 부가시킨 고기능성 도료에 대한 관심이 날로 증가하고 있다. 특히 일본 및 유럽에서는 이에 대한 연구가 활발하게 진행되고 있는 실정이다.In general, the paint is mainly applied to the wall of the structure in consideration of waterproof and aesthetics, or to the steel surface in order to prevent corrosion, but the purpose is gradually changed as the industrial development and the use of automobiles increase. It is becoming. That is, as the pollution level in the air is intensified, interest in high-performance paints that add an air cleaning function to the paints that have been applied aesthetically on the outer wall of the structure is increasing day by day. Especially in Japan and Europe, research on this is being actively conducted.
본 발명은 상기와 같은 요구를 충족시키기 위하여 제안된 것으로서, 공기청정기능 뿐만 아니라 실생활에서 흔히 접하게 되는 휘발성 유기화합물 및 균류에 대한 제거 기능을 부가한 휘발성 유기화합물(VOC) 제거 및 항균성 광촉매 도료 조성물을 제공함에 그 목적이 있다.The present invention has been proposed in order to meet the above requirements, and the volatile organic compound (VOC) removal and antimicrobial photocatalyst coating composition which adds the air cleaning function as well as the volatile organic compounds and fungi that are commonly encountered in real life. The purpose is to provide.
상기와 같은 본 발명의 목적은 광촉매 및 그 조촉매, 항균제 등을 포함하는 휘발성 유기화합물 제거 및 항균성 광촉매 도료 조성물에 의해 달성된다.The object of the present invention as described above is achieved by the removal of volatile organic compounds and antimicrobial photocatalyst coating compositions including photocatalysts and their cocatalysts, antibacterial agents and the like.
상기 도료 조성물은 광촉매 30 ~ 40중량부, 내화안료 10 ~ 20중량부, 실란계결합제 5 ~ 10중량부, 항균제 1중량부 이하, 흐름방지제 5 ~ 10중량부, 광촉매의 조촉매 5중량부 이하 및 잔부로서 무기계 바인더를 포함함을 특징으로 한다.The coating composition is 30 to 40 parts by weight of the photocatalyst, 10 to 20 parts by weight of the refractory pigment, 5 to 10 parts by weight of the silane binder, 1 part by weight or less of the antibacterial agent, 5 to 10 parts by weight of the flow inhibitor, 5 parts by weight or less of the cocatalyst of the photocatalyst. And an inorganic binder as the remainder.
이하에서는 본 발명의 상기와 같은 구성에 관하여 상세하게 설명할 것이며, 특별한 언급이 없는 한 중량부는 도료 조성물 전체 중량을 기준으로 한 것이다.Hereinafter, the configuration as described above of the present invention will be described in detail, and unless otherwise specified, parts by weight are based on the total weight of the coating composition.
광촉매(photocatalyst)는 빛을 이용하여 휘발성 유기화합물을 분해·제거하는 역할을 하는 첨가제로서, 그 함량은 30~40 중량부로 한다. 광촉매를 30중량부 미만으로 첨가시에는 휘발성 유기화합물을 분해·제거하는 속도가 기대치에 미달된다. 또한 도료에 요구되는 물성을 위해 첨가되는 다른 첨가제와의 함량을 고려할 때, 광촉매 함량의 상한치는 40중량부 이하로 하는 것이 바람직하다. 한편, 광촉매로 사용될 수 있는 화합물로는 TiO2(anatase), TiO2(rutile), ZnO, CdS, ZrO2, V2O5, WO3등이 있다. 그러나 ZnO 및 CdS는 할로겐 화합물의 분해에는 탁월한 효과를 갖지만, 촉매 자신이 빛을 흡수·분해되어 Zn, Cd와 같은 유해한 중금속을 발생시키는 문제점이 있다. 또한 WO3는 특정 물질에 대해서만 광촉매로서의 역할을 하게 되는 단점이 있다. 따라서 본 발명에서는, 광학적 활성이 있으면서 광부식은 없어서 안정하고 생물학적으로나 화학적으로는 비활성이며 가시광선 및 자외선 영역의 빛을 이용할 수 있는 TiO2(anatase)를 광촉매로 선택하였다.Photocatalyst is an additive that serves to decompose and remove volatile organic compounds using light, and its content is 30 to 40 parts by weight. When the photocatalyst is added at less than 30 parts by weight, the rate at which the volatile organic compounds are decomposed and removed is less than expected. In addition, considering the content with other additives added for the physical properties required for the paint, the upper limit of the photocatalytic content is preferably 40 parts by weight or less. On the other hand, compounds that can be used as a photocatalyst include TiO 2 (anatase), TiO 2 (rutile), ZnO, CdS, ZrO 2 , V 2 O 5 , WO 3 and the like. However, although ZnO and CdS have an excellent effect on the decomposition of halogen compounds, there is a problem that the catalyst itself absorbs and decomposes light and generates harmful heavy metals such as Zn and Cd. WO 3 also has the disadvantage of serving as a photocatalyst only for certain materials. Therefore, in the present invention, TiO 2 (anatase), which is optically active and has no photocorrosion, is stable, biologically and chemically inactive, and can use light in the visible and ultraviolet regions, was selected as a photocatalyst.
MBL촉매는 상기 광촉매의 활성을 높여 휘발성 유기화합물의 제거 효율을 향상시키는 조촉매(cocatalyst)로서 첨가된다. MBL촉매는 본 출원의 발명자가 직접 제조한 것으로써, MBL촉매 전 중량에 대하여 산화망간(manganese oxide) 40 중량부, 탄산리튬(lithium carbonate) 30 중량부, 산화비스무트(bismuth oxide) 30 중량부를 혼합하여 600℃에서 4시간 반응시키고, 다시 실온으로 냉각하여 잘게 부순 다음 800℃에서 6시간 동안 반응시켜 제조된다. 이러한 MBL촉매는 경제적인 측면을 고려하여 5 중량부 이하로 첨가되는 것이 바람직하다.MBL catalyst is added as a cocatalyst to increase the activity of the photocatalyst to improve the removal efficiency of volatile organic compounds. MBL catalyst is manufactured directly by the inventor of the present application, 40 parts by weight of manganese oxide, 30 parts by weight of lithium carbonate, 30 parts by weight of bismuth oxide, based on the total weight of MBL catalyst 4 hours at 600 ° C, cooled to room temperature again, crushed finely, and then reacted at 800 ° C for 6 hours. The MBL catalyst is preferably added at 5 parts by weight or less in consideration of economic aspects.
항균제는 병원성 대장균 O-157, 살모넬라(salmonella) 등과 같은 세균류 및 흑곰팡이, 청곰팡이 등과 같은 진균류를 제거하기 위한 첨가제로서, 그 함량은 1 중량부 이하로 하며, 무기계 항균제를 사용하는 것이 바람직하다. 함량이 1 중량부를 초과하여도 성능에는 이상이 없으나, 경제적인 측면을 고려하여 1 중량부 이하로 첨가한다.The antimicrobial agent is an additive for removing bacteria such as Escherichia coli O-157 and salmonella, and fungi such as black mold and blue mold, and the content thereof is 1 part by weight or less, and it is preferable to use an inorganic antimicrobial agent. Even if the content exceeds 1 part by weight, there is no abnormality in performance, but in consideration of economic aspects, it is added at 1 part by weight or less.
실란계 결합제로는 아미노계 실란, 에폭시계 실란, 클로로계 실란, 메르캅토계 실란 등이 있으며, 그 첨가량은 5 ~ 10 중량부로 한다. 만일 실란계 결합제가 5중량부 미만으로 첨가되면 기타 첨가제의 혼합력이 떨어지는 문제점이 발생되며, 10 중량부를 초과하여 첨가되면 도료 조성물이 쉽게 뭉쳐지는 현상이 일어나게 된다.Examples of the silane binder include amino silane, epoxy silane, chloro silane, mercapto silane, and the like. The addition amount is 5 to 10 parts by weight. If the silane-based binder is added less than 5 parts by weight, there is a problem in that the mixing power of the other additives fall, if more than 10 parts by weight of the coating composition is easily aggregated.
흐름방지제로는 aerosil-200, Benton-38, Clay Vallac super 등이 사용되며, 그 첨가량은 5 ~ 10 중량부로 한다. 흐름방지제가 5 중량부 미만으로 첨가되면 혼합물의 점성이 낮아져서 작업시 부착면으로부터 쉽게 흘러내려 작업의 효율성을 떨어뜨리는 문제점이 발생되며, 10 중량부 이상으로 첨가되면 혼합물의 점성이 너무 높아져서 작업시에 쉽게 접착되지 않는 문제점이 발생된다.As the flow inhibitor, aerosil-200, Benton-38, Clay Vallac super, etc. are used, and the amount added is 5 to 10 parts by weight. If the flow inhibitor is added in less than 5 parts by weight, the viscosity of the mixture is lowered, which easily flows away from the attaching surface. Problems arise that do not easily adhere.
내화안료로는 안티몬 및 BUSAN 11M을 적정비로 혼합하여 10 ~ 20 중량부를 첨가하여, 화재로부터 구조물을 보호하도록 한다. 내화안료가 10 중량부 미만으로 첨가되면 화재로부터 구조물을 보호하는 효과가 거의 없으며, 20 중량부를 초과하면 본 발명이 의도하는 휘발성 유기화합물 제거 및 항균이라는 목적을 위해 첨가되는 첨가제들의 양이 상대적으로 불충분해지게 되므로, 내화안료의 첨가량은 10 ~ 20 중량부로 한다.As a refractory pigment, antimony and BUSAN 11M are mixed at an appropriate ratio to add 10 to 20 parts by weight to protect the structure from fire. When the refractory pigment is added in less than 10 parts by weight, there is little effect of protecting the structure from fire, and when it exceeds 20 parts by weight, the amount of additives added for the purpose of removing volatile organic compounds and antibacterial intended by the present invention is relatively insufficient. Since it becomes, the addition amount of a refractory pigment shall be 10-20 weight part.
기타성분으로 무기계 바인더를 첨가하여 본 발명인 휘발성 유기화합물 제거 및 항균성 광촉매 도료 조성물을 얻는다.An inorganic binder is added as other components to obtain the volatile organic compound removal and antimicrobial photocatalyst coating composition of the present invention.

Si powder is a heat-resistant chemical additive and Junsei (Japan), TiO 2 (rutile) is used as a target for comparison with TiO 2 (anatase), titanium Korea, and as a general coating of Comparative Example 4 product of Gwangtex Corporation.
표 1과 표 2를 살펴보면, 비교예 1과 비교예 2는 TiO2가 anatase이거나 rutile 구조라는 점만이 다르나, rutile의 경우 촉매로서의 성능이 전혀 없는 것으로 나타났다. 비교예 3은 비교예 1에 비하여 조촉매인 MBL촉매가 첨가된 것으로 휘발성 유기화합물인 NH3와 H2S의 제거에는 탁월하였으나, 병원균 박멸에는 그 효과를 전혀 볼 수 없었다. 반면 본 발명에 따르는 실시예 1과 실시예 2는 휘발성 유기화합물인 NH3와 H2S의 제거뿐만 아니라 병원균 박멸에 소요되는 시간도 20시간 미만이라는 우수한 효과를 나타내었다. 특히 실시예 1은 조촉매인 MBL촉매가 실시예 2의 절반만이 첨가되었음에도 휘발성 유기화합물 제거에 소요되는 시간은 비슷한 것으로 나타났다. 비교예 4는 보통 사용되는 도료로, 휘발성 유기화합물 제거 또는 병원균 제거 중 어느 시험에서도 만족스러운 결과를 나타내지 못하였다.Looking at Table 1 and Table 2, Comparative Example 1 and Comparative Example 2, except that the TiO 2 is anatase or rutile structure only, it was found that rutile has no performance as a catalyst at all. In Comparative Example 3, MBL catalyst as a promoter was added as compared to Comparative Example 1, and was excellent in removing volatile organic compounds NH 3 and H 2 S, but the effect was not seen at all in eradicating pathogens. On the other hand, Example 1 and Example 2 according to the present invention showed an excellent effect that the time required for the elimination of pathogens as well as the removal of volatile organic compounds NH 3 and H 2 S is less than 20 hours. Particularly, in Example 1, the time required for removing the volatile organic compound was similar, even though only half of Example 2 was added to the MBL catalyst as a promoter. Comparative Example 4 is a commonly used paint, which did not show satisfactory results in any of volatile organic compound removal or pathogen removal.
이상의 결과를 종합하였을 때, MBL촉매는 광촉매인 TiO2(anatase)의 활성을 더욱 높여주는 조촉매임을 알 수 있으며, 항균제인 AS116P는 도료 조성물에 첨가되더라도 항균이라는 본래의 성능을 발휘하는 것으로 나타났다.Based on the above results, it can be seen that the MBL catalyst is a cocatalyst that further enhances the activity of the photocatalyst TiO 2 (anatase), and AS116P, an antimicrobial agent, has been shown to exhibit inherent performance of antimicrobial even when added to the coating composition.
개시된 본 발명의 휘발성 유기화합물 제거 및 항균성 광촉매 도료 조성물은 휘발성 유기화합물의 제거 효과가 아주 탁월하며, 병원성 대장균 O-157이나 살모넬라균 등의 세균류와 흑곰팡이나 청곰팡이 등의 진균류의 제거효율이 우수한 것으로 나타났다. 따라서 본 발명의 도료 조성물은 병원 등의 공공건물, 산업화 공장, 고속도로의 차음벽, 지하 콘크리트 구조물 등에 쉽게 적용가능하여, 종래의 미관 및 방수·방청의 기능에 더하여 상기와 같이 우수한 효과를 동시에 얻을 수 있다.Volatile organic compound removal and antimicrobial photocatalyst coating composition of the present invention is very excellent in the removal effect of volatile organic compounds, and excellent in the removal efficiency of bacteria such as pathogenic E. coli O-157 or Salmonella and fungi such as black mold or blue mold Appeared. Therefore, the coating composition of the present invention can be easily applied to public buildings such as hospitals, industrial plants, sound insulation walls of highways, underground concrete structures, and the like, and in addition to the functions of conventional aesthetics and waterproofing and rusting, excellent effects as described above can be simultaneously obtained. .
