High-strength and low-abrasion automobile brake pad

Abstract

The invention discloses a high-strength and low-abrasion automobile brake pad. The high-strength and low-abrasion automobile brake pad is characterized in that a raw material comprises, by weight, 12-15 parts of nitrile rubber, 15-20 parts of tyre powder, 6-8 parts of polytetrafluoroethylene, 3-5 parts of graphite, 2-4 parts of calcium carbonate, 4-6 parts of modified phenolic resin, 1-1.5 parts of a friction increase agent, 2-3 parts of calcined coke, 0.6-0.8 part of zirconium silicate, 0.8-1.2 parts of lead sulfide, 2-4 parts of mixed fibers and 2-4 parts of titanium dioxide. By means of recycling of the tyre powder in the high-strength and low-abrasion automobile brake pad, waste can be fully utilized, resources and energy can be recycled to create economic benefits, and the beneficial effect of being high in carbon content and porosity is achieved; the friction coefficient and the service life are guaranteed through the mixed fibers, and meanwhile brake noise can be effectively absorbed in the brake process; and the manufactured brake pad is good in abrasion resistance and small in high-speed and high-temperature declining, the average friction coefficient is 0.30 mu, the friction coefficient during automobile high-speed braking is 0.30 mu, and the friction coefficient and safety are high.

Description

technical field [0001] The invention belongs to the technical field of automobile brake pads, in particular to an automobile brake pad with high strength and low wear. Background technique [0002] Brake pads are the most critical safety parts, and all braking effects are determined by the brake pads, so good brake pads are the protectors of people and cars. Brake pads are generally composed of steel plates, bonded heat insulation layers and friction blocks, wherein the heat insulation layer is composed of materials that do not conduct heat for the purpose of heat insulation. The friction block is composed of friction material and adhesive, which is squeezed on the brake disc or brake drum to generate friction during braking, so as to achieve the purpose of vehicle deceleration and braking. Due to friction, the friction block will be gradually worn, generally speaking, the lower the cost of the brake pads, the faster the wear. After the friction material is used up, the br...
