Abstract
The invention provides a high-temperature-resistance radial heterogenous magnetic ring. The high-temperature-resistance radial heterogenous magnetic ring sequentially comprises a magnetic ring body, an insulating coating and a high-temperature-resistance coating from inside to outside, wherein the magnetic ring body is a neodymium-iron-boron magnetic ring, the insulating coating is an epoxy coating, and the high-temperature-resistance coating is an organic silicon coating; and the thickness of the epoxy coating is 100-200 microns, and the thickness of the organic silicon coating is 100-200 microns. The high-temperature-resistance radial heterogenous magnetic ring has the technical effects that magnetism reduction cannot be caused even a magnetic body is subjected to relatively strong corrosion.
Description
Technical field
The present invention relates to a kind of high temperature resistant footpath anisotropy magnet ring, belong to technical field of magnetic materials.
Background technology
Magnet ring is a kind of novel cheap and good-quality AF panel device, is utilize high magnetic conductive material, oozes metals such as closing other one or more magnesium, zinc, nickel, burns poly-forming at 2000 DEG C.It is anti-interference element conventional in electronic circuit, has certain impedance operator, has good inhibitory action for high-frequency noise.Be applicable to computer monitor, printer, photocopier, digital camera, communication apparatus, household electrical appliance, communication power supply, winding displacement, power line, USB linear system row anti-jamming effectiveness.Its effect is equivalent to low pass filter, solves power line preferably, and the High-frequency Interference of holding wire and connector suppresses problem.And have and use simple, convenient, effectively, the series of advantages such as take up room little.Disturbing magnet ring with anti-thousand and suppress electromagnetic interference (EMI), is economical and convenient and effective method.
Under certain environment for use, if magnet is subject to higher temperature, magnetic can be caused to decline, therefore improve the heat-resisting quantity of magnet.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of high temperature resistant footpath anisotropy magnet ring is provided.
High temperature resistant footpath of the present invention anisotropy magnet ring, from inside to outside, be made up of magnet ring body, insulating coating and high-temperaure coating successively, described magnet ring body is magnetic Nd-Fe-B ring, described insulating coating is epoxy coating, described high-temperaure coating is organic silicon coating, and the thickness of described epoxy coating is 100-200 micron; The thickness of described organic silicon coating is 100-200 micron.
The thickness of described epoxy coating and the thickness of organic silicon coating are 1:1.
High temperature resistant footpath of the present invention anisotropy magnet ring, has following technique effect: even if magnet is subject to higher temperature, and magnetic also can not be caused to decline.
