Problems solved by technology

[0002] At present, with the increase of automobile speed and the increasing awareness of environmental protection, the automobile industry has put forward higher requirements for the comprehensive performance of brake pads. At present, the brake pads used in my country are divided into asbestos friction materials according to the friction materials used. Material brake pads and semi-metallic friction material brake pads, asbestos brake pads mainly contain asbestos, and the asbestos content is about 30-45%. In the high temperature state after emergency braking, the friction coefficient will be seriously reduced, affecting driving safety and short service life. , and the dehydrated asbestos dust formed under high temperature wear has a strong carcinogenic effect on the human body and serious environmental pollution; semi-metallic brake pads are prone to rust and noise due to high content of steel fibers
