Abstract

The invention relates to a pearl pigment technology, in particular to a composite mica cerium titanium pearl pigment and a preparation method thereof. CeO2-mica pearl pigment is a yellow pearl pigment which is obtained by cladding oxide CeO2 on the surface of mica pearl pigment by a liquid phase cladding method, but has poor glossiness. The composite mica cerium titanium pearl pigment comprises aCeO2-mica substrate on which TiO2 oxide is cladded, and the cladding rate of TiO2 is 1-20%. The surface glossiness of TiO2-CeO2-mica pearl pigment prepared by multi-layer cladding is much higher thanthat of the CeO2-mica pearl pigment, and the color of the yellow CeO2-mica pearl pigment is turned into bright yellow instead of being covered by the cladded CeO2, thus having better luster effect and color effect than the pearl pigment cladded with single-layer CeO2.

Description

technical field [0001] The invention relates to pearlescent pigment technology, in particular to a composite mica-cerium-titanium pearlescent pigment and a preparation method. Background technique [0002] Pearlescent pigments are widely used in coatings, pigments, cosmetics and other industries. CeO 2 -Mica pearlescent pigment is coated with oxide CeO on the surface of mica pearlescent pigment by liquid coating method 2 , a yellow pearlescent pigment is obtained, but its gloss is not enough. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide good gloss and can increase yellow CeO 2 -Composite mica-cerium-titanium pearlescent pigment with brightness of mica pearlescent pigment and preparation method thereof. [0004] Technical scheme of the present invention: composite mica cerium titanium pearlescent pigment, including CeO 2 - Mica substrate, in CeO 2 - TiO coated on mica substrate 2 Oxides, TiO 2 The coverage rate is 1 to 20%. ...
