Embodiment 1

[0064] Prepare the following materials in parts by weight: 100 parts of sendust powder with an average particle size of 60 μm obtained by mechanical crushing (in this sendust powder, the mass fraction of silicon is 9.7%, and the mass fraction of aluminum is 5.8%, the mass fraction of iron is 84.5%), 120 parts of solvent ethanol, 0.2 part of ball milling aid stearic acid, 1500 parts of diameters are 5mm stainless steel balls. Put the prepared material into a sand mill and grind for 10 hours to obtain the primary powder; then dry the primary powder in a vacuum oven and heat-treat it at 750°C for 2 hours under an argon atmosphere to obtain the secondary powder; then the secondary powder Through a 100-mesh sieve, the average particle size is 51um, and the bulk density is 0.51g / cm 3 , a finished baseless magnetic glitter pigment with an aspect ratio of 32. Mix 10g of the above-mentioned substrateless magnetic glitter pigment with 90g of standard NC-acrylate paint, apply the result...

Abstract

The invention provides base-material-free magnetic flash pigment .The base-material-free magnetic flash pigment is flaky powder made of a metal soft magnetic material, the average particle size of the base-material-free magnetic flash pigment is 5-200 micrometers, the apparent density is 0.2-1.0 g / cm<3>, and the diameter-thickness ratio is 10-100 .The base-material-free magnetic flash pigment has high permeability and a remarkable angle-dependent optical effect and can be used for decoration and resisting electromagnetic interference .The invention further provides a preparing method and application of the base-material-free magnetic flash pigment.

Description

technical field [0001] The invention relates to the technical field of pigments, in particular to a substrate-less magnetic flash pigment and its preparation and application. Background technique [0002] Glitter pigments are angle-dependent effect pigments, which can appear in different lightness, chroma, and hue colors with different viewing angles, and have a three-dimensional texture. [0003] Angle-following effect refers to metallic flake pigments (especially aluminum powder) and / or metal-like flake pigments (especially mica-based pearlescent pigments) due to their metallic luster and characteristics parallel to the coated object, when containing transparent pigments In the carrier, the gloss and color depth of the glitter pigment will change with the incident angle and viewing angle of the incident light. The glitter pigments are arranged in different layers in the coating film. When the incident light hits each layer of flaky powder, it will be weakened differently ...
