Abstract

The utility model relates to an organic solvent resistant bonded magnet, wherein infiltration glue is filled among the magnetic powder particles of the magnetism. Through filling the infiltration glue among the magnetic powder particles of the magnetism, the bonded magnet is strong in organic solvent resistance, is not softened after being immersed in industrial acetone for three months, is excellent in organic solvent resistance, and can be used in an organic solvent environment.

Description

A kind of bonded permanent magnet of organic solvent-resistant
Technical field
The utility model relates to a kind of bonded permanent magnet of organic solvent-resistant, and particularly a kind of automobile fuel pump motor of filling infiltration glue is used magnet.
Background technology
The Agglutinate neodymium-iron-boron magnet steel has the space of saving, electric efficiency is high, advantages such as long service life, energy-conserving and environment-protective, and what product can be done under the situation of identical power output is littler, and energy consumption is still less.But under some special environment for use, in automobile fuel pump, common Agglutinate neodymium-iron-boron magnet steel can't satisfy the needs of its long-term work, and it is softening to be in particular in that product can be out of shape.The automobile fuel pump motor is one of part of automobile fuel pump electric system most critical with magnet, and the quality of its performance has directly determined the quality of automobile fuel pump motor.
At present; The automobile fuel pump motor can be selected the sintered rare-earth permanent magnetic body for use with the material of magnet; Also can select bonding rare earth magnet for use or contain in the bonded permanent magnet of rare earth element to add ferromagnetic oxide powder, aluminium-nickel-cobalt magnetic powder, metallic element powder etc., or ferrite magnetic material.Oil pump electrical machinery, will be immersed in the organic solvent because operational environment is more abominable with bonded permanent magnet usually for a long time.When the automobile fuel pump motor uses in the organic solvent environment with bonded permanent magnet, might cause the magnet softening transform, finally influence the operate as normal of automotive oil system.Therefore press for and improve the performance of automobile fuel pump motor with the corrosion of magnet organic solvent-resistant, make its can be in the organic solvent environment steady operation for a long time.
Summary of the invention
The utility model technical issues that need to address are to overcome the above-mentioned defective that prior art exists and bonded permanent magnet that a kind of organic solvent-resistant is provided, it can be satisfied in the environment of organic solvent use for a long time.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of bonded permanent magnet of organic solvent-resistant; It is characterized in that; Fill infiltration glue between the magnetic powder particle of said magnet, said infiltration glue is one or more in T90c vacuum infiltration glue, SU-90C vacuum infiltration glue or the Crylate90CEW infiltration glue.
Owing to filled infiltration glue between the magnet magnetic powder particle of the utility model; Therefore, have the ability of stronger organic solvent-resistant, it is softening that this magnet soaks after three months magnet with industrial acetone; Organic solvent resistance is good, can satisfy in the environment of organic solvent and use.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1, a kind of magnet of organic solvent-resistant comprises bonded permanent magnet, between the magnet particle 1 of bonded permanent magnet, fills infiltration glue 2.
The material of above-mentioned organic solvent-resistant magnet can be selected bonding rare earth magnet for use, contain the bonded permanent magnet of rare earth element and mixture or other magnetic materials of ferromagnetic oxide powder, aluminium-nickel-cobalt magnetic powder or metallic element powder etc.
Above-mentioned bonding rare earth magnet is selected for use like Agglutinate neodymium-iron-boron, bonding samarium iron nitrogen, (SmCo is meant Sm to the bonding SmCo 2Co 17Or SmCo 5) one or more compounds.
Above-mentioned filling infiltration glue is a kind of high molecule sealing materials, is preferably to be selected from T90c vacuum infiltration glue, SU-90C vacuum infiltration glue or the Crylate90CEW infiltration glue one or more.
The magnet of the utility model preparation because all there is infiltration glue surface and internal clearance, therefore can use under the environment of organic solvent for a long time.
