Problems solved by technology

At present, the friction blocks of automobile brake pads are mainly made of asbestos-free composite materials, semi-metallic materials or ceramic materials, but these materials are generally prone to dust powder during the braking friction process. If the dust powder is scattered into the air, it will cause air pollution. If it is adsorbed on the hub, it will be difficult to clean and cause corrosion to the hub

Description

Technical field [0001] The invention discloses an efficient and environmentally friendly brake pad and a preparation method thereof, and relates to the technical field of composite friction materials for vehicles and brake pad manufacturing. Background technique [0002] Brake pads are important functional parts of various vehicle braking systems. They are generally composed of a stainless steel base plate and friction blocks. The friction material of the friction blocks converts kinetic energy into heat energy to achieve braking. The performance of friction materials directly affects the safety, reliability and comfort of the braking system. At present, the friction blocks of automobile brake pads are mainly made of non-asbestos composite materials, semi-metallic materials or ceramic materials. However, these materials are generally prone to generate dust and powder during the braking friction process. If the dust powder is dispersed in the air, it will cause air pollution. If ...
