Problems solved by technology

However, the existing metal magnetic powder insulation coating process takes more than 5.9 hours, up to 31 hours. The entire insulation coating process takes a long time, which not only reduces the preparation efficiency of the metal magnetic powder core, but also has high production costs. At the same time, there is no coating device used in conjunction with the coating process, so the preparation efficiency of the magnetic powder core in the prior art is low, which is not conducive to the development of industry and industrialization

Abstract

The invention discloses an insulation coating device for high-efficiency metal magnetic powder and an insulation coating process for the high-efficiency metal magnetic powder matching with the insulation coating device. The insulation coating device has the characteristics of "one tank", "normal temperature operation" and "high automation degree", etc. The insulation coating device is used for carrying out insulation coating to the surface of the metal magnetic powder, and the insulation coating device for the high-efficiency metal magnetic powder has high automation degree; on the premise ofensuring the insulation coating effect of the metal magnetic powder, the insulation coating time of the metal magnetic powder is effectively shortened, and an insulation coating metal magnetic powderproduct can be obtained within 160 min; meanwhile, without limitation on the size of the insulation coating process for the metal magnetic powder, the insulation coating device not only can meet the requirements of (a small batch laboratory of 2 kg, but also can meet) the requirements of a large batch preparation of 50 kg. The cooperative use of the insulation coating device and the process for the high-efficiency metal magnetic powder is beneficial to promoting the industrialization of metal magnetic powder insulation coating and has a huge application market.

Description

technical field [0001] The invention relates to the field of metal magnetic material preparation, and specifically relates to an insulating coating device for high-efficiency metal magnetic powder and a coating process thereof. Background technique [0002] The magnetic powder core is a composite soft magnetic material formed by mixing and pressing ferromagnetic powder and insulating binder. Due to the small particle size of the magnetic powder, it is not easy to form skin effect, and its surface is covered with a layer of insulating dielectric film. The magnetic powder core has high resistivity and low eddy current loss, and is suitable for medium and high frequency (20KHz-1MHz) working conditions. Compared with thin metal strip magnetic cores, magnetic powder cores can be pressed into various special-shaped electronic components such as "E" shape, "POT" shape, ring shape and bar shape according to service conditions. It has been widely used in green lighting, inductors an...
