Description

technical field [0001] The present invention relates to an improved magnetic plastic material. Background technique [0002] Magnetic plastic is a new type of polymer functional material developed in the 1970s, and it is one of the important basic materials in the field of modern science and technology. Ordinary plastics are not ferromagnetic, but special methods can be used to form ferromagnetic materials: one is to try to change the composition of plastics to make them magnetic. Magnetic plastics have the characteristics of both magnetic materials and plastics. Because magnetic plastics have good machining performance, easy molding, high dimensional accuracy, good toughness, light weight, cheap price, and easy mass production, it is very important for the miniaturization and lightweight of electromagnetic equipment. , precision and high performance are of great significance. It can record sound, light, and electricity information, so it is widely used in many fields such...
