Title:
RESIN-BOND CARBONACEOUS BRUSH AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2015208199
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide: a resin-bond carbonaceous brush with a reduced electric resistivity; and a method for manufacturing such a resin-bond carbonaceous brush.SOLUTION: A method for manufacturing a resin-bond carbonaceous brush comprises the steps of: kneading carbon powder and a binder together to prepare a carbonaceous material; granulating the carbonaceous material so as to have an average particle diameter of 0.3 mm or larger; and mixing the carbonaceous material with metal powder after the granulation, thereby preparing a brush material. The percentage of the metal powder to a total amount of the brush material is controlled to be 1-30 wt%. The method further comprises the steps of: compacting the brush material thus prepared; and performing a heat treatment on the compacted brush material at a temperature which never causes the carbonization of a resin in the brush material.
