優れているため、近年の国民生活の高度化や多様化及び
省エネルギー志向に伴い、その適用分野が顕著に拡大し
ている。2. Description of the Related Art Since zinc-based surface-treated steel sheets are excellent in corrosion resistance, their fields of application are remarkably expanding with the recent advancement and diversification of people's lives and energy-saving tendency.

ない。そこでこのような欠点を解消するために種々の提
案がなされている。However, even such a zinc-based surface-treated steel sheet for the purpose of improving the corrosion resistance has a drawback that white rust is mainly generated, and therefore, it can be processed according to each application. White rust cannot be avoided until it is applied. Therefore, various proposals have been made to eliminate such drawbacks.

る。For example, a method of applying anticorrosive oil to a zinc-based surface-treated steel sheet has been proposed. However, this method not only lowers workability due to stickiness of oil, but also requires degreasing work during processing and wastewater treatment of the degreasing liquid generated in the work, and in some cases causes degreasing failure as a factor. However, there is a drawback that defective chemical conversion treatment, that is, zinc phosphate treatment, occurs, and as a result, defective coating is unavoidable.

Such a water-soluble rust preventive agent has excellent corrosion resistance, but on the other hand, handling work is dangerous, and wastewater treatment measures are required corresponding to harmful substances etc. described in the Water Pollution Control Act, Alternatively, it has drawbacks such as high COD and BOD loads in living environment items.

A vaporizable rust preventive agent for protecting various metals such as cadmium, magnesium, lead and alloys thereof from corrosion in various atmospheres is disclosed, and the effective ingredient of the rust preventive agent is 4-
It is described as an H-1,2,4-triazole compound. However, according to the studies made by the present inventors, the required concentration of the above triazole compound is 0.
The high concentration of 5 to 50 g / m 2 , the fact that the triazole compound is effective against zinc is not specifically described in the above publication, and the rust preventive described in the publication is at low temperature. It was found that, in a humid atmosphere, the vapor pressure is lower than that in a hot and humid environment, so that excellent rust preventive performance cannot be exhibited over a long period of time.

った。In view of the present situation, the inventors of the present invention do not have the above-mentioned conventional drawbacks and impart a particularly excellent corrosion resistance to a zinc plate or a zinc-based surface-treated steel plate. Then
We have also conducted extensive research to develop a rust preventive composition that does not require wastewater treatment measures. As a result, they have found that a composition containing a specific triazole compound as an active ingredient can be a desired rust preventive composition, and thus completed the present invention.
