Description
Technical field
The present invention relates to a kind of soft magnetism coating, belong to magnetic powder technical field.
Background technology
It is well known that roll-type weak magnetic separator, roll-type high intensity magnetic separator, tablet high gradient magnetic separator, strong magnetic iron removing belt etc. are forever
Magnetic machine is very common in the assorting room of magnetic mineral.And it sorts face（With ore pulp contact surface）It is smooth non-magnetic
Property metal or nonmetallic surface, are unfavorable for the recycling of microfine magnetic mineral.And common magnetic material in ore dressing, have high
Magnetic flux density and big coercivity, but demagnetization is very difficult, and being made when magnetic coating is used for benficiation machinery surface of it can make
It is difficult into ore deposit is unloaded.
Number of patent application is 2015108944843, and a kind of soft magnetism conductive coating and its preparation method and application discloses
A kind of soft magnetism conductive coating, main component are 50~72 parts of low temperature curing resins, 1~10 part of soft magnetism conductive filler, 28
~50 parts of solvents, 0.2~50 part of dispersant, 1 part of antifoaming agent and 1 part of advection agent.The patent application overcomes the soft of the prior art
The problem of magnetic conducting coating amount of filler is larger is not changing coating in the performances base such as metal surface adhesive force, corrosion resistance
Electric conductivity is improved on plinth；In the case of identical filler additive amount, realize that conductivity increases the effect of an order of magnitude.But
It is the magnetic flux density and coercivity that soft magnetism conductive coating in the patent application does not involve the need for improving the coating
The characteristics of small.
Invention content
For the above-mentioned prior art there are the problem of and deficiency, the present invention a kind of soft magnetism coating is provided.The present invention is prepared into
The soft magnetism coating arrived has higher saturation flux density and relatively low coercivity.The invention is realized by the following technical scheme.
A kind of soft magnetism coating, by following mass percent into being grouped as：Soft magnet powder 20~35%, polyurethane 30~50%, carbon
SiClx powder 10~20%, dimethylbenzene 15~30%, four kinds of component summations are 100%.
The soft magnet powder is iron-nickel alloy, one or any two kinds of mixed-powders in ferro-silicium, and powder size is
0.074mm~0.018mm.
The iron-nickel alloy is Fe50wt% and Ni50wt%.
The ferro-silicium is Fe94wt% and Si6wt%.
The beneficial effects of the invention are as follows：The soft magnetism coating that the present invention is prepared has higher magnetic flux density and relatively low
Coercivity when this coating is applied to magnetic separator working face, due to having higher magnetic flux density, can be strengthened at the magnetic separation stage
For the collecting ability of microfine magnetic mineral；When unloading the ore deposit stage due to smaller coercivity, magnetic mineral is not interfered with
Unload ore deposit；So coating is conducive to improve the rate of recovery and grade of magnetic mineral.
