Copper-free organic ceramic brake pad

Abstract

The invention discloses a copper-free organic ceramic brake pad which comprises an adhesive, a reinforcing material, a friction performance modifier and filler. Modified sulfide, modified graphite, the friction material reinforcing agent and the friction performance modifier are adopted in the formula of a friction material, so that the heat resistance, anti-declining performance, noise reduction property and impact resistance of the friction material are improved, the service life can be prolonged, and the corresponding comprehensive usability of the friction material can be improved. The advantages of stable compression performance, excellent flexibility and lubrication property and the like of the modified sulfide and the modified graphite are used for the formula design of the friction material, so that high-temperature friction performance is guaranteed, high-temperature wear of a product is smaller, friction couple is not damaged, brake noise is reduced, high-temperature cracks are avoided, environmental pollution is reduced, and the like.

Description

technical field [0001] The invention relates to a brake pad in the field of automobile industry, in particular to a copper-free organic ceramic brake pad. Background technique [0002] Brake pads, as key parts of automobiles, are currently being developed from a single material to a composite material, and its quality directly affects the reliability of the machine and the life safety of the operator. The speed, load and safety requirements of machinery are getting higher and higher. High-speed trains, heavy-duty trucks, cars, racing cars, motorcycles and other heavy-duty, high-speed driving, and frequent braking civilian vehicles all respond quickly and have high friction factors. However, high-performance friction materials that are stable, pollution-free, low in density, long in service life and strong in environmental adaptability have put forward urgent requirements. Friction materials with ceramic organic formula content have emerged as the times require, but their tec...

[0002] Brake pads, as key parts of automobiles, are currently being developed from a single material to a composite material, and its quality directly affects the reliability of the machine and the life safety of the operator. The speed, load and safety requirements of machinery are getting higher and higher. High-speed trains, heavy-duty trucks, cars, racing cars, motorcycles and other heavy-duty, high-speed driving, and frequent braking civilian vehicles all respond quickly and have high friction factors. However, high-performance friction materials that are stable, pollution-free, low in density, long in service life and strong in environmental adaptability have put forward urgent requirements. Friction materials with ceramic organic formula content have emerged as the times require, but their technology is not mature enough in our country. There are disadvantages such as poor impact resistance, high temperature decay of friction coefficient, and easy cracks in the product.

And from a microscopic point of view, the surface of the brake pad is uneven. When braking, there are some small protrusions that contact the brake disc, which will result in a low friction coefficient and noise.
