におさえることが必要である。There is no particular limitation on the ratio of the sparingly soluble condensed phosphate-containing substance to the zinc sulfide-containing substance, but usually
The ratio of lead sulfate capacity is preferably from 1/Zoo to 100/1. Regarding the method of using a releasable condensed phosphate-containing substance and a zinc sulfide-containing substance together, it is possible to add them separately when forming a paint, or it is possible to mix them in advance in a dry or wet process and then use them to form a paint. It is possible to add it at the same time. If you want to further increase the stability in water-soluble paints,
A material containing a sparingly soluble condensed phosphate and a material containing zinc sulfide may be mixed and reacted in the form of an aqueous slurry, dried and pulverized before use. The details of the mechanism behind why a poorly soluble condensed phosphate-containing substance and a zinc sulfide-containing substance exhibit stable and excellent rust prevention properties in water-soluble paints are not clear, but zinc sulfide It is presumed that this is because the condensed phosphate is stabilized in the water-soluble paint by #A-soluble zinc sulfide whose solubility does not change easily with changes in P)I. The antirust pigment of the present invention exhibits effective antirust properties not only for water-soluble paints but also for solvent-based paints and oil-based paints. In order to further improve the rust prevention property, an active zinc salt is added to the rust preventive pigment, which is a substance containing a condensed phosphate salt and a substance containing zinc sulfide, which are sparingly soluble in water. As the active zinc salt, inorganic zinc salts such as zinc oxide, zinc hydroxide, zinc silicate, zinc borate, etc., or organic zinc salts such as zinc carboxylate, zinc sulfo/acid, etc. are used. The amount added should be such that the addition does not cause blistering in the coating film, and when added to a water-soluble paint, it must be controlled to an extent that does not destabilize the water-soluble paint.
