Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high-performance brake pad and its processing method, which solves the problem that although the existing brake pads have been improved in terms of wear resistance and corrosion resistance, they are still in some harsh environments. However, it still cannot meet the requirements for the performance of the brake pads. It is impossible to improve the wear resistance and corrosion resistance of the brake pads by modifying the materials inside the brake pads, and it is impossible to improve the wear resistance and corrosion resistance of the brake pads by adding modified silicon Limestone, modified sepiolite, calcined petroleum coke, sand grain powder, wear-resistant reinforcing filler, high manganese alloy fiber and corrosion-resistant reinforcing filler, so that the mechanical properties of the brake pad can be improved by 2-3 times on the original basis , can not expand the scope of application of the brake pads

Description

technical field [0001] The invention relates to the technical field of brake pad production, in particular to a high-performance brake pad and a processing method thereof. Background technique [0002] Brake pads In the braking system of a car, brake pads are the most critical safety parts. The brake pads play a decisive role in the quality of all braking effects. Brake pads are generally made of steel plates, bonded heat insulation layers and friction blocks. The heat insulation layer is composed of non-heat-conducting materials for heat insulation; the friction block is composed of friction materials and adhesives, which are squeezed on the brake disc and brake drum to generate friction during braking, thereby To achieve the purpose of vehicle deceleration braking, from the application object, the brake pads are divided into: brake pads for disc brakes, brake pads for drum brakes and brake pads for large trucks; from the friction material In terms of composition, the brak...
