FIELD OF THE INVENTION The present invention relates to combustion and photocatalytic ceramic coating compositions and coating products using the same, wherein TTIP (titanium tetra isopropoxide), IPA (isopropyl alcohol), MTMS (methyl trimethoxysilane), or TiO 2 (titanium dioxide) Photocatalytic compositions such as CoO (cobalt oxide), MnOx (manganese oxide) or hopcalite (Cu-Mn mixture), platinum compounds and transition metal compounds, etc. The present invention relates to a combustion and photocatalytic ceramic coating composition which can improve indoor air quality by oxidizing and removing harmful gases such as carbon monoxide (CO), which is an incomplete combustion gas, and a coating product using the same.
일반적으로 각종 가스기기나 석유기기 사용 시 불완전연소된 일산화탄소 등의 유해가스로 인하여 두통, 구토, 현기증 및 신경마비 등의 고통과 신체장애가 유발되는 것으로 알려져 있다. In general, the use of various gas or petroleum equipment is known to cause headaches, vomiting, dizziness and nerve palsy and physical disabilities due to incomplete combustion of harmful gases such as carbon monoxide.
일반적으로 주방에서 사용하는 각종 주방용기나 보일러 제품 등에 코팅되는 합성 수지계 내열 코팅제는 오염이 잘되고, 제조시 환경유해물질이 다량 배출될 뿐 아니라, 화재 발생시 유해가스가 다량 배출되는 문제점이 있었고, 또한 음식조리를 위하여 가스기기나 석유기기 등을 사용하여 가열시 불완전 연소로 인하여 발생되는 CO가스 등의 유해가스를 제거할 수 있는 기능이 없기 때문에 조리 과정이나 보일러 사용 과정에서 사용자가 유해가스에 직접 노출됨으로써, 사용자에게 안전한 사용환경을 제공할 수 없는 문제점이 있었다.
In general, synthetic resin-based heat-resistant coatings coated on kitchen utensils or boiler products used in kitchens are well polluted, not only emit large amounts of environmentally harmful substances during manufacture, but also emit large amounts of harmful gases in the event of a fire. Since there is no function to remove harmful gases such as CO gas generated by incomplete combustion when heated by using gas equipment or petroleum equipment, the user is directly exposed to harmful gases during cooking or boiler use process. There was a problem that can not provide a safe user environment.

이하 본 발명에 포함된 광촉매 조성물에 대한 실시예 및 실험예를 설명한다.Hereinafter, examples and experimental examples of the photocatalyst composition included in the present invention will be described.
[실시예][Example]
본 발명에 포함되는 광촉매 조성물은 TTIP(티타늄 테트라 이소 프로폭시드) 25중량%, IPA(이소 프로필 알콜) 35중량%, 결정 크기 1~10nm의 TiO2(이산화티탄) 5중량%, H2O 20중량%, 산 2중량%, BC(부틸 셀로솔브) 6중량%, HPC(Hydro Propyl Cellulous) 5중량%를 혼합하여 구성되고, 연소촉매 조성물은 Pt(백금계) 화합물이 2중량% 포함된다.The photocatalyst composition included in the present invention is 25 wt% of TTIP (titanium tetra isopropoxide), 35 wt% of IPA (isopropyl alcohol), 5 wt% of TiO2 (titanium dioxide) having a crystal size of 1 to 10 nm, and 20 wt% of H2O. , 2% by weight of acid, 6% by weight of BC (butyl cellosolve), 5% by weight of Hydro Propyl Cellulous (HPC), and the combustion catalyst composition contains 2% by weight of Pt (platinum-based) compound.
이하에서 광촉매 조성물의 반응 효과를 도 1을 참조하여 설명한다.Hereinafter, the reaction effect of the photocatalyst composition will be described with reference to FIG. 1.
도 1은 본 발명의 광촉매성 조성물에 의한 시간 경과에 따른 유해가스의 전환율 도표를 나타낸 것이다.Figure 1 shows a conversion chart of the harmful gas over time by the photocatalytic composition of the present invention.
반응물로는 암모니아(NH3), 트리에탄올아민(triethanolamine), 아세트알데히드(acetaldehyde)로 선정하였다.The reactants were selected as ammonia (NH 3), triethanolamine, and acetaldehyde.

도 1은 시간의 경과에 따른 유해가스의 변화율을 나타낸 도표이다.1 is a chart showing the rate of change of harmful gases over time.
즉 최초 80ppm 농도에서 30분이 경과된 후 암모니아(NH3)와 아세트알데히드(acetaldehyde)의 농도는 각각 22ppm 및 25ppm으로, 트리메틸아민(triethanolamine)은 3ppm으로 농도가 확연하게 감소하였음을 볼 수 있으며, 60분이 지나면서 암모니아(NH3)와 아세트알데히드(acetaldehyde)의 농도는 6,7ppm으로, 트리메틸아민(triethanolamine)은 0ppm으로 감소하였으며, 90분이 경과하면서 암모니아(NH3)와 아세트알데히드(acetaldehyde)의 농도 역시 0ppm에 가깝게 감소하였음을 볼 수 있다.That is, after 30 minutes at the initial 80 ppm concentration, the concentrations of ammonia (NH3) and acetaldehyde (acetaldehyde) were reduced to 22 ppm and 25 ppm, respectively, and trimethylamine (triethanolamine) to 3 ppm. As the concentration of ammonia (NH3) and acetaldehyde (acetaldehyde) was reduced to 6,7 ppm, trimethylamine (triethanolamine) was reduced to 0 ppm. After 90 minutes, the concentrations of ammonia (NH3) and acetaldehyde (acetaldehyde) were also increased to 0 ppm. It can be seen that the decrease is close.
따라서 본 발명의 광촉매 조성물의 코팅제가 유해 물질을 분해하는 데 효과적임을 알 수 있다.Therefore, it can be seen that the coating agent of the photocatalyst composition of the present invention is effective to decompose harmful substances.
이하에서는 본 발명의 연소촉매 조성물에 대해 상세히 설명한다.Hereinafter, the combustion catalyst composition of the present invention will be described in detail.
본 발명의 연소촉매 조성물은 연소촉매 산화물로서 MnOx(망간 산화물), 홉칼라이트(Cu-Mn 혼합물), Pt(백금)화합물 및 전이금속 산화물 중 어느 하나의 혼합물을 총 중량대비 0.5~3중량% 포함하도록 한다.The combustion catalyst composition of the present invention contains 0.5 to 3% by weight of the mixture of any one of MnOx (manganese oxide), hopcalite (Cu-Mn mixture), Pt (platinum) compound and transition metal oxide as the combustion catalyst oxide. Do it.
또한 Ag-Mn 혼합 산화물에 Ag 첨가시 일산화타소(CO) 산화 반응에 우수한 효과를 볼 수 있다.In addition, when Ag is added to the Ag-Mn mixed oxide, an excellent effect on the oxidation reaction of the titanium monoxide (CO) can be seen.

촉매의 반응성은 다양한 산화 상태, Mn4 +/3+ 또는 Mn3 +/2+를 갖는 MnOx 촉매의 산화한원 성질과 산화물 격자 내의 산소 유동성과 연관되어 진다.The reactivity of the catalyst is determined by various oxidation states, Mn 4 + / 3 + or It is associated with the oxygen oxidative properties in the oxide lattice and the oxide nature of the MnOx catalyst with Mn 3 + / 2 + .
한편 도 2는 연소촉매성 혼합물에 의한 PtTiO2 및 PtTiO2-SiO2의 온도 변화에 따른 일산화탄소의 산화반응 결과인 CO conversion(CO 전환율)의 변화를 나타낸 도표이다.On the other hand, Figure 2 is a diagram showing the change in CO conversion (CO conversion) which is a result of the oxidation reaction of carbon monoxide with the temperature change of PtTiO2 and PtTiO2-SiO2 by the combustion catalyst mixture.

두 촉매의 반응성의 차이는 사용된 지지체에 기인하며, TiO2 촉매가 TiO2-SiO2 촉매에 비해 반응활성이 약간 높은 것은 사용된 촉매와 활성 물질인 Pt 사이의 상호작용에 기인하는 것이다.The difference in reactivity between the two catalysts is due to the support used, and the slightly higher reaction activity of the
Pt와 TiO2 사이에 강한 결합이 형성되어(SMSI:Strong Metal Support Interaction), Pt의 소결현상을 억제하나, SiO2는 Pt와의 상호 작용이 약하여(WMSI:Weak Metal Support Interaction) SiO2의 높은 비표면적에도 불구하고 상대적으로 Pt의 소결현상이 심하여 일산화탄소의 흡착점이 적을 것으로 판단된다.Strong bonds are formed between Pt and TiO2 (SMSI: Strong Metal Support Interaction), which suppresses the sintering of Pt, but SiO2 has weak interaction with Pt (WMSI: Weak Metal Support Interaction), despite the high specific surface area of SiO2. Pt sintering is relatively high, and the adsorption point of carbon monoxide is low.
한편 SiO2의 사용이 불가피할 경우, SiO2 위에 Ti를 고정하여 Pt와 지지체 간의 상호작용을 높이면 반응활성이 증가할 것으로 판단된다.On the other hand, if the use of
