Field of the Invention The present invention relates to a rust preventive pigment for an organic rust preventive paint, and more particularly, to an rust preventive pigment for an organic rust preventive paint having good long-term rust preventive property on a metal surface to be coated.

る。2. Description of the Related Art A rust-preventive paint containing a large amount of zinc powder as a rust-preventive pigment, that is, a zinc-rich paint, is a metal, especially a steel, such as a ship, a bridge, and various structures. Is widely used as anti-rust paint.

The paint is combined with a very small amount of binder and adhered to the steel surface. is there. This zinc-rich paint is a paint designed based on the anti-rust effect of zinc powder, and is used as a shop primer, as a thick-film type zinc-rich paint with a film thickness of about 50 to 75 μm, and as a heavy-duty anticorrosion paint. Is done.

が多く、一層の良好な防錆効果が期待されている。As a matter of course, it is desirable that the coating once applied has a long-lasting rust-preventive effect. In particular, in the case of large-scale structures or marine structures, it is difficult to perform repainting work and repair work of a coating film. Therefore, in order to reduce the frequency of these works, it is expected to maintain a long-term rust prevention effect. Further, since ships and marine structures are exposed to severe environments, rust prevention effects are often lost and rust is generated in a short period of time, and further better rust prevention effects are expected.

度では充分な防錆効果は期待できない。[0005] The zinc-rich paint currently used is a combination of a granular zinc powder having a particle size of about 3 to 5 µm and an organic or inorganic binder. Here, an epoxy resin or the like is used as an organic binder, and an alkali silicate or an alkyl silicate is used as an inorganic binder. The content of zinc powder in this rust preventive paint is generally 70% by weight in terms of dry film concentration,
Preferably, the amount is more than 80% by weight, and if the concentration is less than this, a sufficient rust-preventing effect cannot be expected.

Another problem is that the coating workability is impaired due to the problem of zinc fume generation.

There's a problem. Although zinc-rich paint using an organic binder such as an epoxy resin does not have such a problem, it does not sufficiently satisfy various properties such as the above-mentioned good long-term rust resistance, adhesion, and weather resistance.
