Attapulgite-based iron oxide red composite pigment and preparation method thereof

The invention discloses an attapulgite-based iron oxide red composite pigment and a preparation method thereof, wherein the attapulgite-based iron oxide red composite pigment comprises the following raw materials in percentage by mass: 0.02%-0.4% of a dispersant, 0.2%-1% of an antifoaming agent, 5%-10% of iron oxide red, 0.5%-10% of attapulgite, and the balance being deionized water. The pigment with better color performance and stability is obtained by controlling the ratio of the attapulgite to the iron oxide red, the content of the dispersant, the dispersing and grinding rate and other conditions. The preparation method of the composite pigment provided by the invention can effectively improve the dispersity and uniformity of the iron oxide red pigment, has the advantages of excellent pigment performance, simple method, simple operation and the like, and provides a more efficient, environment-friendly and convenient method for producing the iron oxide red composite pigment. 本发明公开了一种凹凸棒石基氧化铁红复合颜料及其制备方法，按质量百
