Abstract
The invention relates to a novel magnetic material, which is prepared from the following components in parts by weight: 55 to 65 parts of raw material iron powder, 20 to 25 parts of raw material neodymium powder, 1 to 2 parts of raw material neodymium powder, 2 to 5 parts of iron oxide, 0.8 to 2 parts of barium carbonate, 0.8 to 8 parts of strontium carbonate, 0.8 to 1.5 parts of sodium chlorate, 0.8 to 1.5 parts of lanthanum oxide, 2 to 4 parts of auxiliary element, 1 to 2 parts of adhesive and 1 to 2 parts of lubricant. According to the novel magnetic material adopting the technical scheme, a plurality of elements are added, so that the coercivity and the corrosion resistance of the magnetic material are remarkably improved; in addition, the adhesive and the lubricant are added, so that the adhesive strength of the magnetic material is strengthened to a certain extent, and the fluidity of the magnetic material is improved to a certain extent.
Description
Technical field
The present invention relates to a kind of material prescription, especially a kind of novel magnetic materials.
Background technology
Neodymium iron boron is one of conventional magnetic material, and it applies to every field.But in conventional art, NdFeB material by
In the inner portion's composition is single, and often with all kinds of defects, for example, coercivity is relatively low, corrosion resistance and temperature performance compared with
Difference, it can cause suitable impact to NdFeB material.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of novel magnetic materials, and it can effectively improve the magnetic of magnetic material
Performance and remaining service behaviour.
To solve above-mentioned technical problem, the present invention relates to a kind of novel magnetic materials, it is by following component according to weight hundred
Divide and formed than configuration：55～65 parts of raw material iron powder, 20～25 parts of raw material neodymium powder, 1～2 part of raw material boron powder, 2～5 parts of ferrum oxide, carbon
0.8～2 part of sour barium, 0.8～8 part of strontium carbonate, 0.8～1.5 part of sodium chlorate, 0.8～1.5 part of lanthana, 2～4 parts of auxiliary element,
1～2 part of composition of 1～2 part of binding agent and lubricant.
As a modification of the present invention, the auxiliary element by one or more in dysprosium, cobalt, tantalum mixture structure
Into.
As a modification of the present invention, described adhesive by the one kind in epoxy resin, chlorinated polymeric ethylene, nylon or
Various mixture is constituted.
Used as a modification of the present invention, the lubricant is by fatty acid, alcohols, aluminium sesquioxide, silicon dioxide
One or more mixture constitute.
Using the novel magnetic materials of above-mentioned technical proposal, it inside it by adding multiple element so that magnetic material
The coercivity of material, and corrosion resistance is obviously improved；Meanwhile, it passes through the addition of binding agent and lubricant so that
The bonding strength of magnetic material increases with mobility.
Specific embodiment

1～2 part of 0.8～1.5 part of sour sodium, 0.8～1.5 part of lanthana, 2～4 parts of auxiliary element, 1～2 part of binding agent and lubricant
Constitute.
Used as a modification of the present invention, the auxiliary element is made up of the mixture in dysprosium, cobalt, tantalum.
Used as a modification of the present invention, described adhesive is by the mixture in epoxy resin, chlorinated polymeric ethylene, nylon
Constitute.
Used as a modification of the present invention, the lubricant is made up of fatty acid with the mixture of aluminium sesquioxide.
Using the novel magnetic materials of above-mentioned technical proposal, it inside it by adding multiple element so that magnetic material
The coercivity of material, and corrosion resistance is obviously improved；Meanwhile, it passes through the addition of binding agent and lubricant so that
The bonding strength of magnetic material increases with mobility.
Technological means disclosed in the present invention program are not limited only to the technological means disclosed in above-mentioned embodiment, also include
The technical scheme being made up of above technical characteristic combination in any.
