Abstract

A magnetic Fe3O4 nano-particle / flake aluminium pigment composite nanometer material is disclosed. The composite nanometer material is prepared by in-situ synthesis of Fe3O4 nano-particles on surfaces of flake aluminium particles by a high-temperature oil phase method. A preparation process is green, safe, and free of pollution to the environment. According to the composite nanometer material, when the composite nanometer material is added into a pigment matrix, the Fe3O4 nano-particles are uniformly distributed in the pigment matrix and are not liable to agglomerate, and distribution of a magnetic field is more uniform.

Description

technical field [0001] The invention relates to the field of nanomaterials, in particular to a magnetic Fe 3 o 4 Nanoparticle / Flake Aluminum Pigment Composite Nanomaterials. Background technique [0002] Flaky aluminum pigments have good metallic luster effect and color flop effect, and are widely used in construction, automobile, paint, chemical and ink industries. However, ordinary aluminum pigments are not magnetic and cannot respond positively under a magnetic field changes in the magnetic field. At present, the following reports on the research on the synthesis of magnetic nanoparticles / sheet structure composites can be seen: [0003] The United States "Journal of the American Chemical Society" (Journal of the American Chemical Society, from page 9082 of volume 134 in 2012) reported a synthetic Fe 3 o 4 A nanoparticle / graphene composite approach that utilizes Fe 3 o 4 Nanoparticles and graphene solution were mixed directly, followed by hydrothermal treatment to p...
