Abstract
China as a large export of iron oxide pigments, iron oxide pigments production is out of low level. So in this paper, the effects of different modifiers and dosage on the dispersion of ultrafine iron oxide red pigment in aqueous solution and dry dispersion were studied by dry surface modification method. At the same time, we analyse the mechanism of modifier and iron oxide red. Finally, it is concluded that the best modifier formula for improving the dispersion performance of superfine iron oxide red pigment in aqueous solution and dry state is modifier D3008. Experiments show that the modified ultrafine iron oxide red pigment with the formula is strong, and can have better dispersion stability in aqueous solution.
