Classification and introduction of Mica titanium pearlescent pigments

2020-05-07
Mica titanium pearlescent pigments can be roughly classified into three types: silver-white, rainbow, and colored. Silver-white pearlescent pigments, because white light reflects on the titanium surface of mica and does not transmit light, can only present a single silver-white phase, but due to the difference in the particle size of mica and the coating rate of TiO2, it will appear as a visual angle Pearl-like mercerized changes. It is the most versatile pearlescent pigment, but it has poor hiding power. The rainbow type is coated with a layer of TiO2 or other metal oxides with higher refractive index, such as Fe2O3, Cr2O3, SnO2, etc., on the flaky mica substrate, and it is excellently produced through multi-level reflection and interference of light. Pearl effect and flop effect. Since this type of pigment both reflects light and transmits light, light at certain wavelengths is strengthened, while others are weakened to exhibit different hue. The biggest advantage of rainbow-type pearlescent pigments is that they can be matched like ordinary pigments, and the resulting complex color is bright and beautiful. The coloring type is based on two kinds of pearlescent pigments of silver white type and rainbow type, and then add a coloring pigment or a dye capsule. This kind of pigment can absorb some light in the visible spectrum. If the reflection color of the absorbing color and the oxide coated mica pigment have the same hue, then the absorption color increases, and the color can be seen at all angles; if the hue is different, it can only be The reflection color is seen at the mirror angle, and the color of the absorption pigment is seen at other angles. Between these two extremes, the transition color can be seen. The pigmented pearlescent pigments are optical pigments that utilize the pearlescent and colored materials of mica titanium to absorb some of the visible light and become a class of pigments with a full spectrum of color and a bright color.
