More specifically, the present invention relates to an anti-w# pigment & II paraboloid that does not contain harmful metals, can be used in various paint vehicles, and has excellent rust-preventing effects.
〔従来の技術]

昭53−39894号公報、特開昭50−104799
号公報、特公昭53−31495号公報など)。[Prior Art] Conventionally, anti-rust pigments for oil-based paints and solvent-based paints include chromium-based pigments (e.g., zinc chromate, strontium chromate, etc.), lead-based pigments (e.g., red lead, basic lead chromate, etc.). lead cyanamide, calcium leadate, etc.)
, phosphate pigments (e.g., zinc phosphate, calcium phosphate, etc.), molybdate-based pigments (e.g., zinc molybdate, etc.), boric acid-based pigments (e.g., barium metaborate, etc.), etc. were used (e.g., Japanese Patent Publication No. 53-39894, Japanese Patent Publication No. 50-104799
(Japanese Patent Publication No. 53-31495, etc.).

面で問題があった。Among these, chromium-based rust-preventing pigments and lead-based rust-preventing pigments have some excellent rust-preventing effects, but since chromium and lead are toxic metals, they pose safety concerns such as harming human health. There was a problem.

However, there were problems in that it lacked versatility, especially in terms of durability and deteriorated some paint resins.

使用範囲を広げ、汎用性を高めているのである。That is, when condensed phosphates dissociate in water, they release polyphosphate ions that have a strong effect of sequestering iron ions, so they have a strong rust-preventing effect.In the present invention, among these condensed phosphates, , by using fine particles with a particle size of 5 μm or more and 5% by volume or less, which has a particularly excellent rust preventive effect, and by using a zinc compound and/or an alkaline earth compound. By neutralizing the pH of the condensed phosphate and preventing the condensed phosphate from degrading the coating resin, we are expanding the scope of use of the coating resin and increasing its versatility. .

本発明において、防w#顔料組成物の構成成分として水
に難溶性の縮合リン酸塩を用いるのは、前記のように、
縮合リン酸塩は鉄イオンなどの封鎖作用が大きく、防錆
効果が優れているからである。In the present invention, the reason why a condensed phosphate salt which is sparingly soluble in water is used as a component of the anti-w # pigment composition is as described above.
This is because condensed phosphates have a strong sequestering effect on iron ions and the like, and are excellent in rust prevention effects.

水に不溶性の場合には防錆作用をまったく発揮すること
ができないからである。In addition, the requirement that it be poorly soluble in water is that if it is poorly soluble, it will gradually exert its rust prevention effect as needed.
This is because the excellent rust prevention effect can be maintained for a long period of time.For example, if it is easily soluble in water, even if the rust prevention effect is excellent, the rust prevention effect will not last for a long time, and if it is insoluble in water, the rust prevention effect will not last for a long time. This is because, in this case, no antirust effect can be exerted at all.

It is preferable to set it to 10. In other words, if the proportion of the condensed phosphate is less than the above range, the excellent rust prevention effect will not be exhibited, and if the proportion of the condensed phosphate exceeds the above range, the acidity will be too strong and may cause deterioration depending on the resin. This is because there is a risk of being exposed.
