Description of the Related Art Double corrosion protection coating of zinc plating and organic coating is often used for corrosion protection of steel structures in a strongly corrosive environment such as a coastal zone. This is because, in the case of a steel substrate, corrosion of the steel under the coating film progresses due to mechanical damage of the organic coating film or permeation of moisture through the coating film, and the volume expansion of rust at that time is severe, so that coating is performed. The peeling of the film will increase,
This is because if zinc plating is applied to the base, such a problem does not occur because the volume expansion of rust is small in addition to the good corrosion resistance of zinc itself. In particular, as an organic coating on zinc plating, powder coating that can easily form a thick coating film,
Alternatively, double-corrosion protection coating using reaction-curing baking coating has extremely high durability, so it is an important structure and requires long-term maintenance-free protection, such as for bridge facilities and telephone poles in coastal areas. Used in

適用が限定されていた。[0003] However, this double anticorrosion coating has problems such as that the cost of galvanizing the steel material is large and that the adhesion of the coating film on the galvanization is not easy. For this reason, as described above, the application has been limited particularly to a structure requiring high reliability.

May be used for undercoating of cold-setting paints.
However, zinc-rich paint cannot be applied as a base treatment for baking coating involving high-temperature heating, which is excellent in adhesion of the coating film and coating film performance, because zinc-rich paint is destroyed by heat.

It is intended to provide a method for forming the same.

ものである。Means for Solving the Problems To achieve the above object, a coating method according to the present invention comprises heating a steel object to be treated to a predetermined temperature and then mixing the zinc fine particles with a fluid immersion tank or the like. After the paint etc. are brought into contact and the baking coating in which the zinc fine particles are dispersed is formed as the inner layer, the powder coating etc. that do not contain the zinc fine particles are brought into contact with the object to be processed and the inner layer coating film themselves while not cooling. Then, a powder coating of a resin is formed on the inner layer to form a double anticorrosion coating film.

After spraying a powder coating material mixed with zinc fine particles on an object to be processed by an air gun or the like, heating to a predetermined temperature, and forming a powder coating in which the zinc fine particles are dispersed as an inner layer, immediately containing the zinc fine particles. No powder coating is sprayed, and then heated if necessary to form a resin powder coating on the inner layer, similarly forming a double anticorrosion coating.

悪くなるおそれがあり、反対に２０μｍを越えると均一
な塗膜ができにくくなる。The above zinc fine particles may be in the form of fine particles or flakes. When the zinc fine particles are flake-like particles, the average thickness is preferably about 10 μm or less and the average major axis is about 500 μm or less. If the size is larger than the above-mentioned size, it becomes difficult to form a uniform coating film. When the zinc fine particles are in the form of fine particles, the average particle diameter is preferably 5 to 20 μm. 5
If it is less than μm, handling may be inconvenient and the working efficiency may be degraded. Conversely, if it exceeds 20 μm, it becomes difficult to form a uniform coating film.

If the amount is less than 5%, the effect of the inner layer in which the zinc fine particles are dispersed as described later is reduced, while if it exceeds 30%, the adhesion of the coating film may be insufficient.

防食塗装が可能となる。According to the present invention, formation of an inner layer in which zinc fine particles serving as a function of galvanizing are dispersed and formation of an outer layer as an anticorrosion coating can be processed in a series of steps of powder and baking coating.
Double anticorrosion coating is possible at almost the same cost as baking coating of ordinary steel structures.

に塗装する場合に比べ高い密着力が得られる。Further, the inner layer in which the zinc fine particles are dispersed can effectively prevent the peeling of the coating film due to the volume expansion of rust generated in the case of the steel base material as well as the galvanized layer, and the sacrificial anticorrosive action of zinc allows the inner layer to disperse. The effect of preventing corrosion of steel when moisture permeates the surface of the steel substrate can also be expected. Furthermore, since the steel base and the resin are in direct contact and adhere to each other, a higher adhesive force can be obtained as compared with the case of painting on a galvanized surface.
