ANTICORROSIVE PIGMENT, AND USE THEREOF

PROBLEM TO BE SOLVED: To provide a metallic pigment having a remarkably higher stability in an aqueous medium than a metallic pigment of the prior art, and capable of being simply agitated without any further action so that it is easily dispersed into an aqueous medium.SOLUTION: In the invention, mo...

Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a metallic pigment having a remarkably higher stability in an aqueous medium than a metallic pigment of the prior art, and capable of being simply agitated without any further action so that it is easily dispersed into an aqueous medium.SOLUTION: In the invention, modified metal particles are manufactured by a manufacturing method characterized: in that (a) in a first treating step, metal particles are distributed into an aqueous dispersion agent; and (b) in a subsequent second treating step, the metal particles dispersed in the first treating step (a) are covered with a layer of an inorganic base, especially by a coating.SELECTED DRAWING: None 【課題】本発明の目的は、先行技術の金属顔料と比較して水性媒体中での安定性が著しく高く、さらなる作用なしに簡単に撹拌して水性媒体中に容易に分散させることができる陰極防食のための金属顔料を提供することにある。【解決手段】本発明は、改質金属粒子が、（ａ）第１の処理工程において、金属粒子が水性分散剤中に分配されること、および、（ｂ）続く第２の処理工程において、第１の処理工程（ａ）で分散された金属粒子が、無機ベースの層、特にコーティングによって被覆されることを特徴とする製造する方法によって製造されることにある。【選択図】なし
