Abstract

The invention discloses a corrosion-resisting brake pad. The corrosion-resisting brake pad comprises raw materials including, by weight, 50-70 parts of epoxy resin, 30-40 parts of boron phenolic resin, 22-30 parts of nitrile rubber powder, 12-16 parts of carbon fiber, 12-16 parts of glass fiber, 6-10 parts of steel wool, 4-8 parts of calcium silicate powder, 4-8 parts of graphite, 4-8 parts of mixed metal powder, 6-10 parts of a corrosion resisting agent, 3-5 parts of a binding agent, 3-5 parts of a curing agent, 3-5 parts of an abrasion resisting agent and 3-5 parts of an anti-aging agent. The invention further discloses a preparing method of the corrosion-resisting brake pad. According to the corrosion-resisting brake pad and the preparing method thereof, the corrosion-resisting brake pad has excellent inflaming retarding and heat resisting performance, the brake pad has good corrosion resisting capability, the strength of the brake pad can be better improved, and the current development requirement is met.

Description

technical field [0001] The invention relates to the technical field of brake pad preparation, in particular to a corrosion-resistant brake pad and a preparation process thereof. Background technique [0002] Brake pads are also called brake pads. In the braking system of a car, the brake pads are the most critical safety parts. The brake pads play a decisive role in the quality of all braking effects, so good brake pads are the protectors of people and cars. Brake pads are generally composed of steel plates, adhesive insulation layers and friction blocks. The steel plates must be painted to prevent rust. During the painting process, SMT-4 furnace temperature tracker is used to detect the temperature distribution during the painting process to ensure the quality. The heat insulation layer is composed of materials that do not conduct heat, and the purpose is heat insulation. The friction block is composed of friction material and adhesive, which is squeezed on the brake disc...
