Description
본 발명은 광촉매가 혼합된 도료조성물에 관한 것으로서, 보다 상세하게는 광촉매가 혼합되어 반영구적인 항균기능을 가지므로 생활주변물에 도장하면 쾌적하고 위생적인 환경을 조성할 수 있는 광촉매가 혼합된 도료조성물에 관한 것이다.The present invention relates to a paint composition in which a photocatalyst is mixed. More specifically, since the photocatalyst is mixed and has a semi-permanent antibacterial function, the paint composition is mixed with a photocatalyst which can create a pleasant and hygienic environment when coated on a living periphery. It is about.
일반적으로 광촉매는 비교적 적은 에너지를 갖는 자외선에 의해 고에너지상태로 여기되는 물질로서, 자외선에 의해 전도대로 여기되어 전자를 방출하고 그 표면에는 플러스전기를 띤 정공이 생성된다. 이때 방출된 여기전자는 강한 환원력을 가지며, 정공은 강한 산화력을 가지는데, 이러한 여기전자와 정공의 산화환원력에 의해 각종 유기물질이 분해되거나 살균된다. 이러한 광촉매는 종래에는 주로 오폐수처리시 각종 독성, 난분해성 유기물질을 산화분해시키는데 사용되었다.In general, a photocatalyst is a material that is excited in a high energy state by ultraviolet light having a relatively low energy. The photocatalyst is excited with a conduction band by ultraviolet light to emit electrons, and a positive electric hole is generated on the surface thereof. At this time, the excitation electrons emitted have a strong reducing power, and the holes have a strong oxidizing power. Various organic materials are decomposed or sterilized by the redox power of the excitation electrons and the holes. Such photocatalysts have conventionally been used to oxidatively decompose various toxic and hardly decomposable organic substances in wastewater treatment.
한편, 우리가 생활하는 공간 속에는 수많은 먼지가 있으며, 이 먼지들은 유기물과 무기물로 이루어져 있다. 그리고 유기물먼지 중에는 각종 유독한 세균이 기생하므로 이러한 세균들을 제거할 수 있는 효과적인 수단이 요구된다.On the other hand, there is a lot of dust in the space where we live, and these dusts are composed of organic and inorganic materials. In addition, since various toxic bacteria are parasitic among organic dust, an effective means for removing these bacteria is required.
본 발명은 상기의 문제점과 광촉매의 특성에 착안하여 제안된 것으로서, 본 발명의 목적은 금속이 코팅된 광촉매가 혼합되어 반영구적인 항균기능을 가지므로생활주변물에 도장하면 쾌적하고 위생적인 환경을 용이하게 조성할 수 있는 광촉매가 혼합된 도료조성물을 제공하는 것이다.The present invention has been proposed in view of the above problems and the characteristics of the photocatalyst, and an object of the present invention is to mix a metal-coated photocatalyst and have a semi-permanent antibacterial function, so that it is easy to provide a comfortable and hygienic environment when painted on living materials. It is to provide a paint composition mixed with a photocatalyst that can be easily formulated.
도 1은 본 발명에 의한 도료조성물의 항균효과를 시험한 그래프1 is a graph for testing the antimicrobial effect of the paint composition according to the present invention
본 발명에 따르면, 액상도료나 분체도료와 같은 통상의 도료에 광촉매를 혼합하여 이루어져서, 피도장물에 도장하면 광촉매에 의한 항균효과를 얻을 수 있도록 된 것으로서, 상기 광촉매는 그 표면에 철이나 칼슘, 백금 등과 같은 금속이 코팅된 것을 특징으로 하는 광촉매가 혼합된 도료조성물이 제공된다.According to the present invention, a photocatalyst is mixed with a conventional paint such as a liquid paint or a powder paint, and when the coated product is coated, an antibacterial effect can be obtained by the photocatalyst, and the photocatalyst has iron, calcium, Provided is a coating composition in which a photocatalyst is mixed with a metal such as platinum.
본 발명의 다른 특징에 따르면, 상기 광촉매는 산화티탄의 표면에 철이나 칼슘, 백금 등과 같은 금속이 코팅된 것을 상기 액상 또는 분체도료에 0.5~2중량%로 혼합하는 것을 특징으로 하는 도료조성물이 제공된다.According to another feature of the invention, the photocatalyst is provided with a coating composition, characterized in that the coating of a metal such as iron, calcium, platinum, etc. on the surface of the titanium oxide in 0.5 to 2% by weight in the liquid or powder coating do.
이하, 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
본 발명은 일반적인 액상도료나 분체도료에 산화티탄(TiO2)에 철이나 백금, 로듐, 칼슘 등과 같은 금속을 광촉매를0.5~2중량% 첨가한 것이다. 상기 광촉매는 380㎚정도의 비교적 적은 빛에너지에 의해서도 전도대로 여기되는 반도체물질로, 산화티탄이 가장 대표적이다.In the present invention, 0.5 to 2% by weight of a photocatalyst is added to metal oxides such as iron, platinum, rhodium, and calcium to titanium oxide (TiO 2 ) in general liquid paints and powder paints. The photocatalyst is a semiconductor material that is excited by the conduction band even by relatively small light energy of about 380 nm, and titanium oxide is most representative.
한편, 상기 산화티탄은 일반적으로 도료의 제조시 착색제로 사용되는 것이다. 그러나 종래의 도료에서 착색제로 사용된 산화티탄은 광촉매로서 작용하지 못하였다. 그 이유는 명백하지는 않지만 산화티탄이 광촉매로서 작용하기 위해서는 산화티탄이 광여기되어 전자가 방출되고 정공이 생성되어야 하나, 종래의 도료에서는 광여기된 산화티탄에서 방출되는 전자가 이동될 전도성물질이 산화티탄의 주변에 없어서 전자의 방출과 정공의 생성이 효과적으로 이루어지지 못하였기 때문인 것으로 가정된다. 따라서 본 고안에서는 상기 광촉매로 산화티탄의 표면에 철이나 백금, 칼슘 등과 같은 금속을 코팅시킨 것을 사용한다. 이와 같이 산화티탄에 ??이나 백금, 칼슘 등을 코팅시키면 산화티탄이 광여기되어 생성된 전자가 그 표면에 지지된 금속을 통해 용이하게 이동하므로 광촉매반응내에 있는 입자의 정공 또는 전자의 양이 증가된다. 따라서 광촉매에 의한 산화, 환원반응이 효과적으로 이루어진다. 또한, 이와 같이 표면에 금속이 코팅된 산화티탄을 혼합하여야만 상기 액상 또는 분체도료의 색상이 변화지 않으면서, 광촉매효과를 얻을 수 있는 것이다.On the other hand, the titanium oxide is generally used as a colorant in the production of paint. However, titanium oxide used as a colorant in conventional paints did not function as a photocatalyst. The reason is not clear, but in order for titanium oxide to act as a photocatalyst, titanium oxide must be photo-excited to emit electrons and holes. It is assumed that it is not in the vicinity of titanium, and the emission of electrons and the generation of holes were not effectively performed. Therefore, in the present invention, the photocatalyst uses a metal such as iron, platinum, calcium or the like coated on the surface of the titanium oxide. In this way, coating ??, platinum, calcium, etc. on the titanium oxide photo-excites the titanium oxide, and the electrons generated easily move through the metal supported on the surface thereof, thereby increasing the amount of holes or electrons in the particles in the photocatalytic reaction. do. Therefore, the oxidation and reduction reaction by the photocatalyst is effectively performed. In addition, the titanium oxide coated with a metal on the surface should be mixed to obtain a photocatalytic effect without changing the color of the liquid or powder coating.
그리고 표면에 금속이 코팅된 산화티탄을 종래의 액상 또는 분체도료에 0.5~2중량% 첨가한다. 도 1에 도시된 바와 같이 산화티탄을 2중량% 이상 사용하여도 2중량% 사용하는 경우와 거의 동일한 수준의 효과밖에 얻을 수 없다. 따라서 산화티탄이 고가라는 점을 감안할 때 2중량% 이상 사용하는 것은 경제적인 면에서 바람직하지 않다. 또한, 산화티탄을 0.5중량% 이하 사용하는 경우에는 소요되는 수준의 효과를 기대할 수 없다.Then, 0.5 to 2% by weight of titanium oxide coated with metal on the surface is added to a conventional liquid or powder coating. As shown in FIG. 1, even when using 2% by weight or more of titanium oxide, only the same effect as that used when using 2% by weight can be obtained. Therefore, considering that titanium oxide is expensive, it is not economical to use more than 2% by weight. In addition, when the titanium oxide is used in an amount of 0.5 wt% or less, the effect of the required level cannot be expected.
일반적으로 입자의 지름이 작아지면 입자의 표면에너지가 커서 다른 물질과의 혼합시 곤란함이 발생한다. 본 발명에서 사용되는 금속이 코팅된 산화티탄은20~40㎚정도의 입자를 갖는데, 본 발명에서도 상기 금속이 코팅된 산화티탄이 액상이나 분체도료에 고르게 잘 분산되도록 도료와 금속이 코팅된 산화티탄의 혼합시 주의를 기울여야 한다. 만약 금속이 코팅된 산화티탄이 고르게 분산되지 않은 경우에는 금속이 코팅된 산화티탄을 많은 양을 사용하여도 기대되는 수준의 효과를 얻기가 어렵다. 바람직하게는 상기 도료와 금속이 코팅된 산화티탄의 혼합시 도료와 금속이 코팅된 산화티탄을 공기주입공이 형성된 밀폐용기에 넣고, 상기 공기주입공을 통해 공기를 비교적 고속으로 주입하여 공기의 유입속도에 의해 금속이 코팅된 산화티탄이 도료에 효과적으로 분산, 혼합되도록 한다.In general, when the diameter of the particles is small, the surface energy of the particles is large, which causes difficulty in mixing with other materials. Metal oxide coated titanium oxide used in the present invention has a particle of about 20 ~ 40nm, also in the present invention titanium oxide coated with paint and metal so that the metal oxide coated evenly dispersed in liquid or powder coating Care must be taken when mixing. If the metal-coated titanium oxide is not evenly dispersed, it is difficult to obtain the expected level of effect even when a large amount of the metal-coated titanium oxide is used. Preferably, when the paint and the metal oxide coated titanium oxide is mixed, the paint and the metal oxide coated titanium oxide are placed in a sealed container in which an air injection hole is formed, and the air is injected at a relatively high speed through the air injection hole, thereby introducing air. The metal-coated titanium oxide is effectively dispersed and mixed in the paint.
이와 같이 본 발명에 사용된 광촉매는 광에너지에 의해 광촉매가 여기되어 전자가 방출되어 그 표면에 정공이 생성되고, 이 여기전자와 정공은 강력한 산화제인 OH라디칼을 생성한다.As described above, in the photocatalyst used in the present invention, photocatalysts are excited by light energy to emit electrons, and holes are generated on the surface thereof, and the excitation electrons and holes generate OH radicals, which are powerful oxidizing agents.
이러한 광촉매반응을 식으로 도시하면 다음과 같다.This photocatalytic reaction is shown as follows.
TiO2+ UV → e(여기전자) + h+(정공) (1-1)TiO 2 + UV → e (excitation) + h + (hole) (1-1)
e + O2→ O2 -(2-1) e + O 2 → O 2 - (2-1)
2O2 + 2H2O → 2·OH + 2O2 -+ O2(2-2) 2O 2 + 2H 2 O → 2 · OH + 2O 2 - + O 2 (2-2)
h++ OH → ·OH (3-1)h + + OH → OH (3-1)
식 (1-1)은 광촉매에 대한 일반적인 반응이며, 식(2-1)은 여기전자에 의한 OH라디칼 생성반응이고, 식(3-1)은 광촉매표면에서의 정공에 의한 OH라디칼생성반응이다. 이와 같은 반응에 의해 생성된 OH라디칼은 강력한 산화제로서, 이 OH라디칼에 의해 대기중에 있는 각종 유독성 유기물질이나 각종 세균이 분해, 산화된다.Equation (1-1) is a general reaction to a photocatalyst, Equation (2-1) is an OH radical generation reaction by excitation electrons, and Equation (3-1) is an OH radical generation reaction by holes at the photocatalyst surface. . The OH radical produced by such a reaction is a powerful oxidizing agent. The OH radical decomposes and oxidizes various toxic organic substances and various bacteria in the atmosphere.
한편, 이때 광촉매 자신은 산화환원반응에 직접 참여하지 않고 광촉매에 의해 생성된 여기전자와 정공에 의해 산화환원반응이 일어나므로 광촉매에 의해 반영구적인 항균효과를 얻을 수 있다.On the other hand, the photocatalyst itself does not directly participate in the redox reaction, so the redox reaction occurs by the excitation electrons and the holes generated by the photocatalyst, and thus, the photocatalyst may obtain a semi-permanent antibacterial effect.

고려화학제품 제품명 EX4518인 분체도료에 칼슘이 코팅된 산화티탄을 0.8중량% 첨가하여 공기주입공이 형성된 밀폐용기에 담은 후, 상기 공기주입공을 통해 공기를 고속으로 주입하여 상기 도료와 칼슘이 코팅된 산화티탄를 혼합하였다. 이와 같이 하여 제조된 혼합물을 조명기구용 철판에 도장하여 건조시켜 시험편을 만든 후, Escherichia coli ATCC 25922와, Pseudomonas aeruginosa ACTT 15442를 상기 시험편에 접촉시킨 상태에서 24시간 경과후의 생균수를 측정하였다. 이때 원적외선을 조사하면서 KICM FIR 1003시험방법에 의해 시험하였다. 이때 그 결과는 <표 1>과 같았다.After adding 0.8% by weight of titanium oxide coated with calcium to the powder coating of the product name EX4518, it was put in a sealed container in which an air injection hole was formed, and then the air was injected at high speed through the air injection hole to coat the paint and calcium. Titanium oxide was mixed. The mixture thus prepared was coated on an iron plate for luminaires and dried to prepare a test piece, and the number of viable cells after 24 hours was measured in contact with Escherichia coli ATCC 25922 and Pseudomonas aeruginosa ACTT 15442 in contact with the test piece. At this time, it was tested by the KICM FIR 1003 test method while examining the far infrared. The results were as shown in Table 1.

실시예2Example 2
칼슘이 코팅된 산화티탄의 혼합량을 달리하여 실시예 1과 동일한 방법으로 항균시험을 하였다. 그 결과는 도 1의 그래프와 같았다.The antibacterial test was carried out in the same manner as in Example 1 by varying the amount of the calcium oxide coated titanium oxide. The result was as in the graph of FIG.
실시예 2의 결과에 의하면, 상기 산화티탄을 도료에 대해 2중량% 이상 사용한 경우 동일한 수준의 향균효과를 얻을 수 있음을 알 수 있다.According to the result of Example 2, it can be seen that the same level of antimicrobial effect can be obtained when the titanium oxide is used in an amount of 2% by weight or more with respect to the paint.
이상과 같은 본 발명은 표면에 금속이 코팅된 광촉매를 도료에 첨가함으로써, 각종 생활주변물에 도장하여 광촉매에 의한 항균효과를 용이하게 얻을 수 있도록 한다.The present invention as described above by adding a photocatalyst coated with a metal on the surface to the paint, it is possible to easily paint on various living peripherals to obtain an antibacterial effect by the photocatalyst.
이상에서와 같이 본 발명에 의하면, 금속이 코팅된 광촉매를 도료에 혼합하여, 생활주변물에 도장하면 용이하게 광촉매에 의한 항균효과를 얻을 수 있다.As described above, according to the present invention, when the metal-coated photocatalyst is mixed with a paint and coated on a living peripheral material, an antibacterial effect by the photocatalyst can be easily obtained.
특히 본 발명에 의한 도료조성물을 조명기구에 도장하면 햇빛이 들어오지 않는 야간이나 실내에서도 조명빛에 의해 광촉매반응이 일어나 항균효과를 얻을 수 있으므로 실내공기를 항상 쾌적하게 유지할 수 있다.In particular, when the coating composition according to the present invention is coated on a lighting device, the photocatalytic reaction occurs due to the illumination light even at night or indoors where sunlight does not enter, and thus an antibacterial effect can be obtained, thereby keeping the indoor air always comfortable.
