Problems solved by technology

CN104945754A discloses a rubber extruded magnetic strip that improves the suction force. Its function is also to make the magnetic force line be aggregated and strengthened, and the original magnetic force line distribution is further strengthened, so that the magnetic strip is firmly stressed and cannot be moved casually.
It can be seen that this patent is also purely for the purpose of pursuing thinner and smaller volume, greater suction, and firm adsorption, and does not involve the technical effect of dual-character magnetism, because according to the technology brought by the combination of permanent magnet and soft magnetism in this patent The effect must be a decline in the magnetic properties of the magnet, and the purpose of obtaining stronger magnetic properties with a smaller volume cannot be achieved, which runs counter to the purpose of the patent

Abstract

The invention discloses a bipolar magnetic material and a manufacturing method thereof. The bipolar magnetic material is prepared from the following raw materials based on mass percentages: 5-88% of permanent magnet material, 5-88% of soft magnetic material, 6-16% of binder and 1-10% of auxiliaries. Meanwhile, the invention discloses the manufacturing method of the bipolar magnetic material. A bipolar magnet is manufactured by a dual-phase mixing mode without microcosmic interaction coupling, an unexpected magnetic function expansion effect is achieved, and the bipolar magnet is expanded on the aspects of permanent magnet and soft magnet from a magnetized attraction object; bipolar magnetism is expanded on the aspect of the permanent magnet from a magnetic attraction object, so that the minimum value of attractive is increased, a phenomenon of infirm adsorption caused by too small maximum value in permanent magnet self attraction can be overcome, so that attraction is more uniform andobject moving and rotating can be smoother; and the bipolar magnet single-layer structure can realize a soft magnet and permanent magnet matching effect, so that a new field is brought to magnetic products by virtue of the bipolar magnet.

Description

technical field [0001] The invention relates to an amphoteric magnetic material and a manufacturing method thereof. Background technique [0002] Using the magnetic force of the interaction between objects to realize the adsorption, suspension and display of objects has brought a variety of uses to our industrial and civil products, and has changed all aspects of our lives, such as industrial motors and civil magnetics. advertising material. When using magnetic attraction, we usually obtain the maximum magnetic performance with the smallest volume of material, and the macroscopic performance is to obtain the strongest attraction and the attraction is firm and does not weaken with time as the pursuit goal. [0003] The prior art is that the permanent magnet objects can attract each other on the soft magnetic surface, and can move and change directions flexibly and at will. CN201037294Y discloses a ferrous wallpaper. The patent discloses that magnetic products of any polarit...
