Abstract
The invention discloses a granule with an excellent heat conductive performance and strong wear resistant performance and a preparation method thereof. The granule is prepared by the following steps: evenly mixing the following raw materials: calcium carbonate whisker, cryolite, lithopone, flake graphite, diatomite, carbon fiber, foamed iron powder, and adhesive, adding the mixture into a double roller rubber open mill, carrying out melting to melt and plasticize raw materials, and grinding the plasticized materials into granules with a particle size of 8 to 20 meshes. The granule has the advantages that the granule can be added into the friction plate of brake pad according to a certain ratio in order to effectively reduce the hardness and density of friction plate, and at the same time, the brake pad has the advantages of strong wear resistant property and excellent heat conductivity.
