磁性塑料是七十年代发展起来的一种新型高分子功能材料,是现代科学技术领域的重要基础材料之一。磁性塑料按组成可分为结构型和复合型两种,结构型磁性塑料是指聚合物本身具有强磁性的磁体,这类磁性塑料尚处于探索阶段,离实用化还有一定的距离;复合型磁性塑料是指以塑料或橡胶为粘合剂与磁性粉末混合粘接加工而制成的磁体,这类磁性塑料现已实现商品化,目前用于填充的磁粉主要是铁氧体磁粉和稀土永磁粉。
Magnetic plastic is a kind of new polymer functional material developed in seventies, which is one of the important basic materials in modern science and technology. Magnetic plastic composition can be divided into two types of structural and composite, structural magnetic plastic refers to the polymer itself has a strong magnetic magnet, this type of magnetic plastic is still in the exploratory stage, away from the practical and still a certain distance; composite Magnetic plastic refers to the plastic or rubber as a binder and magnetic powder mixed with the magnet made of adhesive processing, these types of magnetic plastic has now been achieved commercialization, currently used to fill the magnetic powder is mainly ferrite magnetic powder and rare earth forever Magnetic powder.
