brake pads

Abstract

The invention discloses a brake pad which comprises a steel backing and friction materials. The friction materials are prepared from components including, by weight, 1-10 parts of butyl butylbenzene, 0.5-2 parts of cumyl hydroperoxide, 0.5-2 parts of epoxy resin, 1-15 parts of boron containing phenolic resin, 1-15 parts of polypropylene, 6-10 parts of nylon powder, 5-10 parts of boron nitride, 0.01-0.05 part of coupling agent, 1-5 parts of dicumyl peroxide, 1-2 parts of sulfur powder, 1-2 parts of benzoic acid, 1-2 parts of stearic acid, 1-2 parts of boric acid, 30-50 parts of graphite, 1-2 parts of reduced iron powder, 1-2 parts of barium sulfate, 0.5-2 parts of bauxite, 0.5-2 parts of feldspar powder, 0.5-2 parts of zinc oxide, 0.01-0.05 part of accelerator, 0.01-0.05 part of anti-aging agent, 0.5-2 parts of fluorite powder, 0.5-2 parts of silicon carbide and 0.5-2 parts of coumarone. The brake pad has the advantages of abrasion resistance, long service life, no spark, no smell, low noise and fine heat dissipation performance.

Description

technical field [0001] The invention relates to the technical field of brake pads, in particular to a brake pad with low cost and long service life. Background technique [0002] Brake pads consist of a steel back and friction material bonded to the steel back. At present, asbestos brake pads are mostly used as brake pad friction materials for vehicles, but asbestos in asbestos brake pads has carcinogenic effect and has a serious impact on people's physical and mental health. When the speed of the brake pad reaches 300 kilometers per hour or above, the temperature of the brake pad can easily reach more than 1000 degrees after braking. Therefore, the brake material is required to be resistant to high temperature and not deformed; At a temperature of 1000 degrees, it is easy to release toxic gas, has a strong smell, and is easy to deform; there are harsh noises and a large number of sparks, which pose a certain safety hazard. In addition, the asbestos in asbestos brake pads ...

AI Technical Summary

Problems solved by technology

At present, asbestos brake pads are mostly used as brake pad friction materials for vehicles, but asbestos in asbestos brake pads has carcinogenic effects and has a serious impact on people's physical and mental health.

When the speed of the brake pad reaches 300 kilometers per hour or above, the temperature of the brake pad can easily reach more than 1000 degrees after braking. Therefore, the brake material is required to be resistant to high temperature and not deformed; At a temperature of 1000 degrees, it is easy to release toxic gas, has a strong smell, and is easy to deform; there are harsh noises and a large number of sparks, which pose a certain safety hazard

In addition, asbestos in asbestos brake pads is difficult to fully bond with other components in the brake pads, and it is easy to peel off, and it is not wear-resistant and has a short service life.
