なオゾン分解用塗料に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an ozone decomposition paint, and more specifically, it employs spinel-type metal oxide particles as an ozone decomposition catalyst and has a built-in corona discharger that generates ozone. The present invention relates to an ozone-decomposing paint that is useful for decomposing ozone by coating it on appropriate parts of OA equipment.
オゾンの発生はいろいろなところでみられる。 Ozone generation can be seen in many places.
中でも、電子写真方式等を採用した装置のコロナ帯電器
からは可成り多量のオゾン発生が認められる。Among these, a considerable amount of ozone is observed to be generated from the corona chargers of devices that employ electrophotographic methods.
ところで、オゾンは弗素につぐ強力な酸化剤となりうる
ものであるが、分解されれば無害な酸素になり二次汚染
の心配もないので例えば空気中の浮遊菌の殺菌、空気中
の臭気物質の脱臭など空気浄化剤として利用されている
。しかし、分解されることなくオゾンがそのまま装置内
に滞留したり。By the way, ozone can be a powerful oxidizing agent second only to fluorine, but once it is decomposed, it becomes harmless oxygen and there is no need to worry about secondary contamination. It is used as an air purifier for deodorizing purposes. However, ozone remains in the equipment without being decomposed.

生するオゾンを分解除去する方法は多く提案されている
。その幾つかをあげれば次のとおりである。Alternatively, it is environmentally undesirable for it to be discharged into the atmosphere from the device. For this reason, many methods have been proposed for decomposing and removing ozone generated by electrophotographic copying apparatuses. Some of them are as follows.
（１）コロナ発生電極のハウジング内面に銀、金、ニッ

いる（特公昭５２−１６７０号公報）。(1) The inner surface of the housing of the corona generating electrode is coated with a metal such as silver, gold, nickel, platinum, or an alloy thereof, and this metal or alloy is used as a catalyst for ozone decomposition. Note that metal oxides such as Ni2O, BaOlCuOlAgz Oz, etc. can also be used as catalysts for ozone decomposition (Japanese Patent Publication No. 1670/1983).

銅又は白金の酸化物の被覆をするには、メツキ、高温度
での加熱及び又は王水を用いた処理が必要があり、処理
工程が複雑な上に公害等を発生させる可能性のある危険
物を用いなくてはならないという欠点がある。However, in (1) above, gold and platinum are themselves very expensive, and the inner surface of the housing is coated with nickel.
Coating with copper or platinum oxide requires plating, heating at high temperatures, and/or treatment using aqua regia, which is a complex treatment process and poses a risk of causing pollution. The disadvantage is that it requires the use of physical objects.
前記（２）においては、実際には、ポリマー粒子を分級

を得なく、従って、コスト高となる。In (2) above, in reality, polymer particles are classified and treated with heat or a softening agent to make them sticky, and then the sticky polymer particles are filled with particles coated with classified bobcalide particles. This necessitates a complicated manufacturing process, resulting in high costs.

いという欠点がある。In (3) above, the production process of the ozone decomposition catalyst is troublesome and expensive, and requires the use of hazardous substances such as nitric acid, sodium hydroxide, and formalin. A disadvantage is that harmful doluol must be used in the process of applying the cracking catalyst.
前記（４）においては、オゾン吸収剤下塗り用とオゾン

いので、特に市場にあっては。In (4) above, there is the hassle of having to prepare two layers, one for the ozone absorber undercoat and the other for the ozone absorber topcoat, and it also requires the use of toxic toluene, so it is particularly difficult to find on the market. Yes.

ものであるが、これがオゾン分解に有効であるとの報告
については本発明者らは不知である。The present inventors have repeatedly conducted research and studies to decompose ozone and make it harmless, and have discovered that spinel-type metal oxides are extremely effective as catalysts for ozone decomposition. The present invention has been made based on this. In addition,

−１に示すごとき結果が得られた。Comparative Examples 1, 2.3 and 4 Instead of the spinel-type metal oxide used in Example 1, activated carbon alone, Bobcaride (M.0280%+), which has conventionally been used as an ozone decomposition catalyst for ozone filters, was used.
75C by the same method as in Example 1 using a manganese dioxide-titanium oxide composite powder (mixing ratio unknown as it is a commercial product), and a silver-manganese dioxide system.
When the ozone decomposition efficiency and life characteristics for up to 150 hours were measured when 0.2g was attached to one side of aluminum, the results shown in Table 1 were obtained.

おいても最もすぐれているのが認められた。When these coating films were examined, it was found that sample Nα9 adhered most strongly to the AQ plate, and because the particle size of the water-dissolved urethane resin was large, it was found that sample Nα9 adhered most strongly to the AQ plate.
It naturally created an exposed surface of 4 particles, and was recognized to have the best ozone resolution.
