Abstract

The invention relates to a wear-resistant magnetic material and a preparation method thereof. The wear-resistant magnetic material includes, by mass parts, 22-25 parts of ferric oxide, 5-10 parts of zinc oxide, 2-5 parts of potassium oxide, 1-3 parts of copper oxide, 13-20 parts of boron trioxide, 12-18 parts of ferric nitrate, 3-6 parts of manganese oxide, 12-15 parts of aluminum cobalt oxide and5-10 parts of additives. The preparation method includes step (1) of weighing the raw materials according to the mass fraction and mixing the raw materials uniformly; step (2) of calcining the mixture in a calcining kiln; step of (3) of ball-milling the obtained mixture; step (4) of performing rubber discharging on the mixture after spray granulation; step (5) of placing the mixture having undergone the rubber discharging into a kiln, introducing a protective gas for sintering; and step (6) of polishing the obtained mixture. The properties of components contained in the obtained magnetic material are stable, and the magnetic material contains components such as silicon dioxide, so the overall abrasion resistance of the mixture is effectively improved.

Description

technical field [0001] The invention specifically relates to a wear-resistant magnetic material and a preparation method thereof. Background technique [0002] Magnetic materials are widely used, and can be used in electroacoustics, telecommunications, electric meters and motors. They can also be used as memory components, microwave components, etc., and can be used to record language, music, image information, etc., and more and more are used in current industrial production. and in life. However, the wear resistance of the existing magnetic materials is insufficient, and phenomena such as wear often occur during use, which reduces the service life of the components. Contents of the invention [0003] In view of the above-mentioned problems in the prior art, the purpose of the present invention is to provide a wear-resistant magnetic material and a preparation method thereof, so as to improve the problem of poor wear resistance of the existing magnetic materials.
