Problems solved by technology

[0004] In above-mentioned two kinds of inventions, no matter be to utilize potassium chlorate to generate ferric oxide or direct precipitation reaction generate ferric oxide as oxidant, it is difficult to precisely control Fe 3+ and Fe 2+ The problem of proportion, the oxidation of potassium chlorate cannot accurately generate Fe 3+ (oxidized by oxygen in the air), and Fe 3+ and Fe 2+ mixed coating, during the reaction and post-treatment process, part of the Fe 2+ will be oxidized to Fe 3+ , resulting in weak or even no magnetism on the surface of the pigment, and at the same time affecting the color effect of the pigment

Abstract

The invention discloses magnetic pearlescent pigment with a 3D (three-dimensional) effect and a preparation method of the magnetic pearlescent pigment. The magnetic pearlescent pigment comprises pearlescent pigment, a magnetic coating and a protecting layer, wherein the magnetic coating is located on one or more pearlescent pigment layers and comprises cobalt oxide, iron oxide and iron protoxide; the protecting layer is located on the magnetic coating; the pearlescent pigment comprises a base material and one or more pearlescent pigment layers. The prepared magnetic pearlescent pigment with the 3D effect can have a stereoscopic and dreamlike 3D effect by utilizing the magnetic tracking phenomenon of a surface magnetism material. By means of the preparation method of the magnetic pearlescent pigment with the 3D effect, the problem that ferrous iron is easily oxidized in the prior art can be solved, loss of ferroferric oxide is reduced, magnetic loss is reduced, part of produced iron cobaltate is stable and not prone to oxidation, and long-time storage of the pigment is guaranteed.

Description

Technical field [0001] The invention relates to a magnetic pearlescent pigment, particularly a magnetic series pearlescent pigment with 3D visual effects and a preparation method thereof, belonging to the field of decorative effect pigments. Background technique [0002] The 3D magnetic series of pearlescent pigments refers to coating a layer of magnetic material on the outside of the substrate, using the magnetic characteristics of the magnetic material to arrange, match, migrate and other behaviors under the action of a static magnetic field. It is used in decorative pearlescent pigments such as printing or spraying. In the field, when the paint is placed in a static magnetic field when it is not completely surface-dried, it can produce a fascinating and shiny dream 3D effect. This product is widely used to create 3D effects in cosmetics, synthetic leather, glass crafts, printing inks, textile printing, packaging materials, handicrafts, etc. [0003] The existing technology main...
