摘要： 优化了自制分散剂 Fa 和润湿剂 Wa 制备水性透明氧化铁红分散体的工艺，探讨了制备的水性透明氧化铁红分散体的性能。 结果表明：当透明氧化铁红用量为 20%（占整个分散体系的质量分数），分散剂 Fa 和润湿剂 Wa 的用量分别为透明氧化铁红用量的 4.0%和 1.0%；在 45Hz 下研磨45 min时，即可获得颗粒小、透明度好、贮存稳定性优异的水性透明氧化铁红分散体。

Abstract: An optimized process for preparing the waterborne transparent iron oxide red dispersion with self-prepared dispersant (Fa)and wetting agent (Wa)was described.The properties of the prepared dispersion were further investigated. The results showed that the transparent iron oxide red pigment dispersion exhibited good particle size, transparency and storage stability when the process satisfied the following conditions: transparent iron oxide red pigment content was 20%, mass ratio of self-prepared dispersant and wetting agent totransparent iron oxide red pigment was 4. 0% and 1 .0% respectively, and milling time was 45 minutes at milling frequency 45 Hz.
