Abstract
Official abstract text for this publication.
A manufacturing method for a magnet includes: a step of obtaining mixed powder of magnetic powder and a lubricant; a step of mixing the mixed powder with an uncured binder that is a silicone composition to attach the binder to a surface of the mixed powder; a step of molding the mixed powder under pressure to obtain a molding, and a step of curing the silicone composition to bind particles of the magnetic powder together,
First claim
Opening claim text (preview).
What is claimed is: 1 . A manufacturing method for a magnet comprising: obtaining mixed powder of magnetic powder and a lubricant; mixing the mixed powder with an uncured binder containing a silicone composition to attach the binder to a surface of the mixed powder; molding the mixed powder under pressure to obtain a molding; and curing the silicone composition to bind particles of the magnetic powder together. 2 . The manufacturing method for a magnet according to claim 1 , wherein the lubricant is a metal soap-based lubricant, and the mixed powder is heated to a temperature equal to or higher than a melting point of the lubricant to attach the lubricant to a surface of the magnetic powder, and the temperature of the mixed powder is lowered to a temperature lower than the melting point to solidify the lubricant. 3 . The manufacturing method for a magnet according to claim 1 , wherein the magnetic powder is one or more of Fe—N-based compounds and R—Fe—N-based compounds (R: rare earth elements). 4 . The manufacturing method for a magnet according to claim 1 , wherein the silicone composition is a thermosetting silicone composition, and the molding is heated to cure the silicone composition. 5 . The manufacturing method for a magnet according to claim 4 , wherein a curing temperature of the silicone composition is lower than a decomposition temperature of the magnetic powder. 6 . A magnet manufactured by the manufacturing method for a magnet as claimed in claim 1 .
