The invention relates to the technical field of brake pads and discloses a preparation method for abrasion-resistant brake pads. The formula of materials comprises 2123 resin, A330 friction particles,modified large-pad graphite, modified small-pad graphite, powdered coke, butyronitrile powder, barite powder, glass fibers, wood fibers and tire powder. In the preparation process, components of different effects are sequentially mixed firstly, then sulfurization crosslinking is conducted under hot pressing, and then heating for solidification and aftertreatment are conducted to obtain the brakepads. Through the modified large-pad graphite and the modified small-pad graphite, the abrasion-resistant and heat-resistant performance of the brake pads is greatly improved. The prepared brake padsare good in abrasion resistance and heat resistance and stable in friction coefficient.
