Abstract
The invention relates to an environment-friendly pearlescent pigment. The problems that an existing pearlescent pigment is unstable in performance and the production is not environmentally friendly are solved mainly. The surface of a kernel is coated with multiple metal oxide layers, the multiple metal oxide layers are one or both of titanium dioxide and iron oxide, a high temperature resistant layer adheres to a surface layer of the multiple metal oxide layers, the outer surface of the high temperature resistant layer is coated with an antibacterial layer, and the high-quality pearlescent pigment product is acquired through a series of physical and chemical treatment. The environment-friendly pearlescent pigment has good antibacterial effect and is stable and durable in performance in a high temperature environment, the manufacturing process is simple, raw materials are saved, the cost is reduced, the environment-friendly pearlescent pigment is environmentally friendly, and the production efficiency is improved.
