Abstract
PURPOSE: To provide a friction material for automobile use, effective to reduce the level of friction noise stably while keeping the friction coefficient, by adding a small amount of expanded graphite to a resin-based friction material containing asbestos as a base.
CONSTITUTION: A friction material composed of (A) a friction material (composed mainly of asbestos and a binder resin, and if necessary, an organic friction-regulating agent, barium sulfate, graphite, etc.) and (B) 0.1W10.0wt% of expanded graphite (thin flakes of graphite obtained by expanding a natural flaky graphite of several tens to several hundreds microns in thickness at a rate of expansion of ≥30). The expanded graphite can be prepared by immersing graphite in a mixed liquid of concentrated sulfuric acid and concentrated nitric acid, washing with water, and rapidly heating the graphite at ≥500°C.
USE: Suitable as a friction material such as disc brake pad, drum brake lining, etc.
