| description | The invention discloses a preparation method of pearlescent pigment, which comprises the following steps: S1, taking pigment substrate powder, putting the pigment substrate powder into atomic layer deposition equipment, vacuumizing, and setting the temperature to be 25-300 DEG C; s2, introducing a precursor A which is WF6; s3, introducing cleaning gas to purge the excessive precursor A and by-products; s4, introducing a reducing precursor B; s5, introducing sweeping gas to sweep the excessive reducing precursor B and by-products; and S6, repeating the steps S2-S5 for 1-100 times to obtain the glittering pearlescent pigment. Compared with the traditional technology, the scheme provided by the invention has the advantages that the uniform and compact metal tungsten layer is plated on the surface of the pigment by adopting the atomic layer deposition process, the brightness and chromaticity are greatly improved, and the flickering effect is better. The method is simple in operation step, the thickness of the cov |
