Abstract
The invention discloses high-abrasion-resistance particles having a noise reduction function and a preparation method of the particles. A formula adopted in the method comprises calcium carbonate whiskers, cryolite, lithopone, flake graphite, kieselguhr, NACF fibers, spherical white vermiculite, butadiene-acrylonitrile rubber powder, hollow aluminium silicate spheres and an F826 adhesive. A preparation technology of the particles comprises steps as follows: raw materials are evenly mixed as per the formula and placed into a double-roll rubber open mill for smelting, the raw materials are fused and plasticized, finally, plasticized materials are crushed to form particles with the particle size ranging from 8 meshes to 20 meshes, and the high-abrasion-resistance particles are obtained. The high-abrasion-resistance particles have the advantages that the hardness and the compactness (density) of friction plates can be effectively reduced, so that the friction plates can absorb noise produced when the friction plates are contacted with brake discs during working; meanwhile, brake linings can have the high-abrasion-resistance characteristic and the good high-temperature declining resistance.
