（特開昭58−61751号公報）。TECHNICAL BACKGROUND Conventionally, it has been known to use flavonoid-containing components obtained by thermally extracting leaves and stems of Camellia plants with ethanol or water as a deodorant for removing spoilage odor and the like.
(JP-A-58-61751).
本発明者は、上記フラボノイド含有成分の消臭以外の
効果について検討した結果、該成分が良好な防錆効果を
奏することを見出し、本発明をなすに至つた。As a result of studying the effects of the above flavonoid-containing component other than deodorization, the present inventor has found that the component has a good rust preventive effect, and has completed the present invention.
因に、このフラボノイド含有成分が防錆特性を有する
ことについては未だ報告は全くみられない。Incidentally, no report has yet been found that the flavonoid-containing component has anticorrosive properties.

〜30％程度に希釈した液が好ましい。The flavonoid used in the present invention is not limited to a plant as a raw material, but a camellia plant is preferable. The flavonoid-containing component is diluted with water or another solvent, preferably a volatile solvent such as ethanol, methanol, acetone or dioxane, or ethylene glycol or propylene glycol. At that time, the flavonoid component is 2
A solution diluted to about 30% is preferable.

内部に塗布しても効果がある。In order to use the flavonoid liquid diluted in this way as an anticorrosive agent, the liquid may be directly applied to or impregnated with or sprayed on the article to be anticorrosive, but the flavonoid-containing component used in the present invention is in a gas phase state. Since it has an anticorrosive effect, it is prepared by impregnating a suitable porous carrier with the above-mentioned liquid diluted with it, and stores rust-prone articles such as metal products made of copper, nickel, iron or alloys. Even if installed in a display box or its drawer or container, it is effective for rust prevention of metal products. It is also effective when applied to the inside of a cabinet or a wooden container for storing metal products.

い。Therefore, the rust preventive agent of the present invention is particularly convenient for use in the rust preventive of articles for which it is desired to avoid direct application, such as piano wires. For example, it is generally known that direct coating of benzotriazole (lubricating oil additive) prevents loss of surface gloss due to rust. However, this is oil-soluble, so it depends on the type of article. However, the present invention does not have such a concern.

価した。Experiment (1) Four glass desiccators (with lids) with a volume of 10 were prepared, and in each of the desiccators, JIS G 3141 standard cold-rolled steel plate test pieces (having a size of 60 cm x 80 cm, with a polishing cloth) were used. One piece (polished) was hung by wire. The atmosphere inside this desiccator was set to 5 p each with SO 2 and H 2 S in the air.
pm content (A), SO 2 and H 2 S in the air, respectively
The one containing 50 ppm (B) and the atmosphere of (A) and (B) of the desiccator, one open desiccator containing 100 ml of flavonoid-containing ethanol solution (ethanol extract of green tea) was opened. And left for 1 month at room temperature. After 1 month, the appearance of rust on the test pieces in each desiccator was evaluated by the appearance according to the JIS K 2246 standard display method.
結果は表１に示すとおりである。 The results are shown in Table 1.
表１にみられるとおり、フラボノイド含有液を雰囲気
中に設置しておくと、試験片に発生する錆は著しく低下
することがわかる。 As can be seen from Table 1, when the flavonoid-containing liquid is placed in the atmosphere, the rust generated on the test piece is significantly reduced.
実験（２） 実験（１）において、フラボノイド含有エタノール液

る。Experiment (2) In Experiment (1), the flavonoid-containing ethanol solution was impregnated into a piece of wood and then dried at room temperature (10 cm x 2 c
m × 3 cm) was used instead of the flavonoid-containing ethanol solution placed in a dish, and the wood chips were placed in a desiccator in an atmosphere in which H 2 S and SO 2 were added at 25 ppm each in the air,
After leaving for 1 month for those that were not placed, the state of rust generation was evaluated in the same manner. The results are shown in Table 2.
なお、デシケータ内に吊した試験片の表面光沢は、木
片を存在させたものでは新品同様の外観を呈した。 The surface gloss of the test piece suspended in the desiccator was similar to that of a new article when the wood piece was present.

られなかつた。Example Rust prevention of cups: A flavonoid-containing ethanol solution (containing about 20% flavonoids) obtained by extracting green tea with ethanol was applied to a cupboard made of a copper-based alloy to adhere to it. It was On the other hand, the one not coated with the ethanol solution was used as a control. When the generation of rust on the surface of the cup was observed for both of them over time, rust was observed after 90 days in the control, but no rust was observed in the one using the present invention.
