Problems solved by technology

[0010] In the existing brake pads, ordinary phenolic resins have the disadvantages of poor thermal ablation and high wear. During emergency braking and high-speed braking, the brake pads become hot due to friction, which easily causes physical and chemical changes in the phenolic resin, and eventually The life of the brake pads is reduced; moreover, in the brake pads that use asbestos as a reinforcing fiber, asbestos has poor thermal conductivity. After repeated use, the brake will cause heat to accumulate in the brake pads. After the brake pads become hot, its braking The performance will change, and even lead to brake failure, causing potential safety hazards; in addition, during the use of semi-metallic brake pad friction materials, the friction coefficient of the brake pads is prone to instability, for example, steel fiber and iron fiber Use, it will make the friction coefficient not stable enough

Description

technical field [0001] The invention relates to the technical field of brake pads, in particular to a friction material for brake pads, a brake pad and a method for preparing the brake pad. Background technique [0002] At present, with the advancement of science and technology, people's quality of life has been greatly improved. As an indispensable tool for people to travel, the safety of a car is directly determined by its braking ability. The most important part, the quality of brake pads is directly related to the effect of car braking. [0003] Generally, the brake pad is composed of a steel plate, an adhesive insulation layer and a friction block. The friction block is composed of friction material and adhesive. When braking, the friction block is squeezed on the brake disc or brake drum to generate friction with it, so as to achieve the purpose of decelerating and braking the vehicle. It can be seen that the friction block determines the performance of the brake pad...
