| titleOfInvention | A kind of rubber magnetic material and its preparation method and application |
| abstract | The invention relates to the technical field of permanent magnets, in particular to a rubber magnetic material and a preparation method and application thereof. The preparation method of the rubber magnetic material includes the following steps: mixing the magnetic powder and the composite binder once to obtain a mixed material; the composite binder includes, in mass percentage, 75% to 90% of nitrile rubber, Acrylate rubber 10% to 25%; mixing the primary mixing material with the coupling agent and performing secondary mixing to obtain a secondary mixing material; calendering the secondary mixing material; The laminated product is laminated, and the temperature of the lamination process is gradually increased from 30° C. to 110° C.; the laminated product is vulcanized to obtain the rubber magnetic material. The tensile strength and temperature resistance of the rubber magnetic material of the present invention are obviously better than those of the traditional rubber permanent magnet material, and the bending property is good, and can not crack under long-term high temperature and high-speed rotation, and can meet the requirements of high-speed motors. |
