Abstract

The invention provides a friction particle which can be prepared by the following methods of: 1) preparing the following materials in percent by mass: 55-73% of grinding dust, 1-3% of phenolic resin, 15-20% of liquid butyronitrile rubber and 7-22% of a first tribological property conditioning agent; and (2) uniformly mixing the materials in proportion, feeding the mixed materials into an internal mixer to be refined for 5-8 minutes, wherein the refining temperature is 80-100 DEG C, and cooling the refined material blocks and crushing so as to obtain the friction particle. The invention further provides a friction material and friction goods with the friction particle. The friction material and friction goods prepared from the friction particle have the advantages of low corrosion loss, high strength, low hardness, low noise and the like.

Description

technical field [0001] The invention belongs to the technical field of friction braking, in particular to a friction particle, a friction material and a friction product containing the friction particle. Background technique [0002] In the production process of brake pads, about 10-15% of the grinding dust will be generated during the grinding process of the size of the brake pads, and the dust is generally discarded, causing environmental pollution.
