Document Type and Number:
WIPO Patent Application WO/2015/162862
Kind Code:
A1
Abstract:
In the present invention, a carbonaceous material is produced by kneading a carbon powder and a binder. The carbonaceous material is granulated to have an average particle diameter of 0.3 mm or greater. A brush material is produced by mixing the granulated carbonaceous material and a metallic powder. The proportion of the metallic powder relative to the total amount of the brush material is adjusted to 1-30% by weight. The resulting brush material is molded under pressure, and is further heat-treated at a temperature at which the resin within the brush does not carbonize.
