| titleOfInvention | A kind of preparation method of neodymium iron boron magnet for automobile ignition coil |
| abstract | The invention provides a method for preparing a neodymium-iron-boron magnet for an automobile ignition coil. S100 prepares a corrosion inhibitor by chlorosulfonated polyethylene, paraformaldehyde and aniline; S200 adopts paraformaldehyde, calcium hydride, chloroform, antioxidant and 3-aminopropyl trimethoxy silicon to prepare antioxidants; S300 mixes one or more of dysprosium and terbium metals or chlorides with ethanol, and adds anti-corrosion agents and antioxidants to form mixed slurry, dysprosium and terbium The metal or chloride of terbium accounts for 1-10% of the mixed slurry, the anti-corrosion agent accounts for 20-30% of the mixed slurry, and the antioxidant accounts for 20-30% of the mixed slurry; S400 prepares NdFeB alloy and assisted diffusion alloy Hybrid flake magnet for scales; S500 evenly coats the mixed slurry on each flake magnet. Thereby, the coercivity, anti-corrosion performance and anti-oxidation performance of the NdFeB magnet are improved. |
