Gold powder and preparation method thereof

Abstract

The invention relates to the field of cosmeticsand, in particular to gold powder and a preparation method of the gold powder. The gold powder comprises a core body, wherein a titanium dioxide coating, a silicon dioxide coating and a ferric oxide coating are sequentially covered on the outer surface of the core body from inside to outside; the preparation method comprises the steps of: uniformly attaching a layer of titanium dioxide particles on the outer surface of the core body; calcining and cooling the core body attached with the titanium dioxide to form a titanium dioxide coating; attaching a layer of silicon dioxide particles on the surface of the titanium dioxide coating; calcining and cooling the core body attached with the silicon dioxide to form a silicon dioxide coating; attaching a layer of ferric oxide particles on the surface of the silicon dioxide coating; and calcining and cooling the core body attached with the ferric oxide to form a ferric oxide coating. According to the gold powder as well as the preparation method of the gold powder, the ferric oxide particles are coated on the outer surface of the silicon dioxide coating and the silicon dioxide is firmly combined with the ferric oxide, therefore, the acid liquid and the alkaline liquid fail to stretch into the joint of the silicon dioxide and the ferric oxide.

AI Technical Summary

Problems solved by technology

[0004] Gold powder is often exposed to acidic or alkaline liquids during storage or use. These liquids will penetrate and corrode the connection between the iron oxide particles and the core, causing the iron oxide particles to fall off and make them lose their golden luster.

And the existing gold powder can't well avoid this kind of problem
