Problems solved by technology

At present, the brake pads used in automobiles are mainly semi-metal brake pads, but the main disadvantages of this product are: (1) high density and high hardness, so it is easy to damage the friction disc, and it is easy to produce vibration and braking noise; (2) ) The thermal conductivity is high, and it is easy to cause air resistance in the braking system at high temperature, which can cause the friction layer to be separated from the steel plate, resulting in dangerous accidents; (3) Steel fibers are prone to rust, and the product is easy to wear decrease in strength and stiffness

Abstract

The invention relates to a ceramic brake pad, and belongs to the technical field of automobile brake. The ceramic brake pad is prepared from the following components: 1-5 kg of acrylonitrile butadiene rubber powder, 5-10 kg of noise reduction powder, 6-10 kg of resin, 3-8 kg of whiskers, 3-8 kg of brass fiber, 1-4 kg of short fiber, 1-5 kg of frictional powder, 1-4 kg of long fiber, 8-16 kg of ceramic fiber, 3-8 kg of high-temperature barium, 4-9 kg of crystalline flake graphite(-195), 0.5-3 kg of iron, 2-6 kg of petroleum coke, 8-13 kg of ceramic additives, 8-13 kg of wear-resisting powder, 0.5-3 kg of aramid fiber, 1-4 kg of wood fiber, 2-6 kg of ceramic toughening agents, 1-4 kg of antimony sulfide, and 3-8 kg of stabilizers. The ceramic brake pad has the characteristics that a friction disk is not damaged, no brake noise is generated, the temperature resistance is high, the service life is long, and stable braking is realized.

Description

technical field [0001] The invention relates to a ceramic brake pad, which belongs to the technical field of automobile braking. Background technique [0002] The automobile braking system is a key system that affects the safety of the automobile, and the stability and reliability of the braking system are directly determined by the comprehensive performance of the brake pads. At present, the brake pads used in automobiles are mainly semi-metal brake pads, but the main disadvantages of this product are: (1) high density and high hardness, so it is easy to damage the friction disc, and it is easy to produce vibration and braking noise; (2) ) The thermal conductivity is high, and it is easy to cause air resistance in the braking system at high temperature, which can cause the friction layer to be separated from the steel plate, resulting in dangerous accidents; (3) Steel fibers are prone to rust, and the product is easy to wear Decreased strength and rigidity. Thereby develo...
