Description

technical field [0001] The invention relates to the technical field of material science, in particular to a magnetic plastic and a preparation method thereof. Background technique [0002] Magnetic plastic mainly refers to plastic products with magnetism, which have the characteristics of low density and high impact resistance. Its products can be processed by cutting, cutting, drilling, welding, lamination and embossing, and are widely used in electronics, Electrical, instrumentation, communication, culture and education, medical and health and many fields in daily life. At the same time, it can be processed into products with high dimensional accuracy, thin walls and complex shapes, and products with inserts can be formed to realize the miniaturization, light weight, precision and high performance of electromagnetic equipment. Therefore, in some new fields, sintered magnets are gradually being replaced by magnetic plastics. At the same time, magnetic plastics consume les...

Problems solved by technology

[0003] However, most of the existing magnetic plastics directly add magnetic powder to the plastic to form a composite magnetic plastic. However, the combination of the magnetic powder and the plastic body is poor, resulting in unstable performance of the magnetic plastic; or the powder is easy to agglomerate in the plastic body. Poor dispersibility, making the magnetic plastic inhomogeneous
