Abstract
(EN)
Disclosed is a method for preparing a high-performance iron oxide red/clay mineral hybrid pigment by mechanochemistry, the method comprising mixing a clay mineral, a soluble iron source and an alkali source in a mill for grinding so as to obtain a precursor, wherein the ratio of balls to materials is controlled at 20-50, the grinding speed is 300-1200 rpm, and the grinding time is 30-360 min; and then calcining the precursor at 500ºC-900ºC for 30-120 min to obtain the high-performance iron oxide red/clay mineral hybrid pigment. The iron oxide red/clay mineral hybrid pigment has a bright and beautiful color, excellent high-temperature and acid resistance, and can satisfy requirements for high-performance iron oxide red pigments in the fields of paints, inks, ceramics, anti-corrosive coatings, etc. Furthermore, the preparation method of the present invention does not produce the three wastes, and is a simple process that is environmentally friendly and suitable for industrialized production, thus it is expected to replace existing production processes of iron oxide red pigments.

La présente invention concerne un procédé de préparation par mécanochimie d'un pigment hybride d'oxyde de fer rouge/minéral argileux de haute performance, le procédé consistant à mélanger un minéral argileux, une source de fer soluble et une source alcaline dans un broyeur afin de les broyer pour obtenir un précurseur, le rapport billes/matériaux étant régulé à 20 à 50, la vitesse de broyage étant de 300 à 1 200 tr/min, et le temps de broyage étant de 30 à 360 min; puis calciner le précurseur à 500 °C à 900 °C pendant 30 à 120 min pour obtenir le pigment hybride d'oxyde de fer rouge/minéral argileux de haute performance. Le pigment hybride d'oxyde de fer rouge/minéral argileux présente une couleur vive et belle, une excellente résistance aux hautes températures et aux acides, et peut satisfaire aux exigences pour les pigments rouges d'oxyde de fer de haute performance dans les domaines des peintures, des encres, des céramiques, des revêtements anticorrosion, etc. En outre, le procédé de préparation de la présente invention ne produit pas les trois déchets. Il s'agit d'un procédé simple qui est respectueux de l'environnement et approprié pour une production à l'échelle industrielle, ce qui devrait permettre de remplacer les procédés de production existants de pigments rouges d'oxyde de fer.
