(Industrial Application Field) The present invention is applicable to corrosion-resistant metals such as rust-preventing treatment before painting of metal products such as steel, repair of unplated parts of galvanized products, and rust-prevention treatment of damaged parts of painted metal products. This invention relates to anticorrosion paints used for surface protection. (Prior Art) Conventionally, as this type of anticorrosive paint, a one-pack type or two-pack type paint has been used, which uses an epoxy resin as a binder and contains zinc powder. (Problems to be Solved by the Invention) However, such conventional one-component paints are cured by air oxidation, and two-component paints are cured by a curing agent, so it takes a long time for the paint to harden. There is a problem that the intermediate coat and top coat cannot be applied immediately, resulting in poor workability. Particularly for metal products such as fences installed outdoors, when repairing damaged plating or paint, the anticorrosion paint requires a long time to harden, making on-site repair work time-consuming and inefficient. There is. (Means for Solving the Problems) In view of the problems of the conventional art, the present inventor has conducted intensive research and has provided an instant-curing anticorrosive paint that solves the above-mentioned problems. The present invention will be explained below. The anticorrosive paint of the present invention uses a cyanoacrylate resin as a binder, and contains zinc or zinc alloy powder mixed therein. Generally, it is produced by uniformly mixing 100 parts by weight of a cyanoacrylate resin and 75 to 90 parts by weight, preferably 80 to 85 parts by weight, of zinc or zinc alloy powder. Zinc or zinc alloy is generally used as a powder having a particle size of about 4 to 10 microns. The anticorrosive paint of the present invention combines the fast curing properties of a cyanoacrylate resin and the excellent anticorrosion performance achieved by the electrochemical action of zinc or a zinc alloy. Examples will be described below in order to clarify the characteristics of the anticorrosive paint of the present invention. (Examples and Comparative Examples) Anticorrosion paint (Example 1) with the formulation shown in Table 1
~3), and apply this paint to a width of 75 mm, a length of 150 mm,
Five test pieces were prepared by coating the surface of a 1 mm thick polished iron plate (SS41) to a thickness of 50μ, and each was kept in a room at a room temperature of 25°C for 30 minutes, 1 hour, 2 hours, 5 hours, and 24 hours after applying the anticorrosive paint. After being left to dry, a salt spray test (JIS-Z-2371) was conducted for one week, and the results were compared to the second test.
Shown in the table. As a comparative example, a commercially available one-component zinc powder-containing zinc-rich paint was used, and a test piece was subjected to a salt spray test in the same manner as in the examples, and the results are shown in Table 2.

It was found that if the subsequent drying time was too short, blisters would occur in the paint film and the adhesion between the paint film and the iron plate would be poor. (Effects of the invention) As detailed above, the anticorrosive paint of the present invention uses cyanoacrylate resin as a binder and contains zinc or zinc alloy powder, so the curing time of the paint can be significantly shortened compared to the conventional one. It has anti-corrosion properties comparable to conventional ones. Therefore, the anticorrosive paint of the present invention can be used to apply intermediate and top coats in a short time, particularly during on-site repair work, improving workability and increasing the work efficiency of workers.
