Description

technical field [0001] The invention relates to the technical field of brake pads, in particular to a high-temperature resistant brake pad. Background technique [0002] In the braking system of a car, the brake pad is the most critical safety part. Brake pads are generally composed of steel plates, bonded heat insulation layers and friction blocks. Among them, the steel plate should be painted to prevent rust; the heat insulation layer is composed of materials that do not conduct heat; the friction block is composed of friction materials and adhesives, which are squeezed on the brake disc or brake drum to generate friction during braking, and at the same time The friction between the tire and the ground converts the kinetic energy of the vehicle into heat energy after friction, so as to achieve the purpose of deceleration and braking of the vehicle. In the process of automobile braking, the comprehensive performance of the friction material will directly affect the safety...
