Beschreibung
Zusammenfassung:The invention relates to a method for adhering neodymium iron boron inorganic hole and cathode electrophoresis composite surface protection, wherein the invention uses inorganic hole agent of potassium metasilicate, liquid glass or lithium silicate whose modules are 3.3-5.4, 3.3 and 4.5, added with inhibitor additive as 0.5-2% hexamethylene tetramine, 0.2-1% bioquin and 0.5-3% sodium molybdatem, under vacuum condition to seal the holes of neodymium iron boron magnet, then processes composite surface protection of electrophoresis coat. The invention has simple operation and semi-automatic operation, to obtain uniform thickness and better insulation property.
