Abstract

The invention relates to multifunctional grinding dust granules for a car brake pad and a preparation method thereof. The method includes the following steps that 40-50 parts of grinding dust, 10-15 parts of NACF fibers, 10-15 parts of calcium carbonate whiskers, 10-15 parts of diatomaceous earth, 10-15 parts of cryolite, 15-20 parts of magnetite powder, 1-2 parts of antimony sulfide, 5-10 parts of barium sulfate, 3-5 parts of lithopone, 3-5 parts of crystalline flake graphite, 20-25 parts of potassium hexatitanate whiskers, 8-15 parts of F826 adhesives, 20-36 parts of spherical white vermiculite, 4-6 parts of nitrile butadiene rubber powder, 25-30 parts of aluminium silicate hollow spheres, 15-20 parts of sepiolite fibers, 8-15 parts of expanded graphite, 5-8 parts of tyre powder, 25-30 parts of carbon fibers and 15-20 parts of porous iron powder are mixed evenly, put into smelting equipment to be smelted and plastified, and smashed into the granules with the grain size being 8-20 meshes, so that the multifunctional grinding dust granules are obtained. The multifunctional grinding dust granules and the preparation method thereof have the advantages that the grinding dust can be recycled, the heat fading performance of a friction plate is improved, the working noise of the friction plate is low, the heat conductivity of the friction plate is good, the abrasion resistance of the friction plate is enhanced, and the service life of the brake pad is prolonged.

Description

technical field [0001] The invention relates to a material of a friction plate in an automobile brake pad and a preparation method thereof, in particular to a multifunctional automobile brake pad grinding ash particle and a preparation method thereof. Background technique [0002] Brake pads are the most critical safety parts in the car braking system, and play a decisive role in the car's braking performance. Brake pads are generally composed of steel plates, adhesive insulation layers and friction plates. When braking, the friction plates are squeezed on the brake disc to generate friction, so as to achieve the purpose of vehicle deceleration and braking. [0003] The friction plate is composed of friction materials and adhesives. The friction materials are composite materials, including metal materials, fiber materials and mineral materials. The use of these materials makes the friction materials generally have a high degree of compactness, and the porosity is extremely l...
