Abstract

A high-performance semi-metallic brake pad comprises the following components according to weight percentages: 4-6% of nitrile rubber powder, 2-4% of tyre powder, 3-5% of crystalline flake graphite, 6-9% of foam iron powder, 9-13% of boron containing phenolic resin, 8-12% of chopped steel fibre, 2-4% of alumina fibre, 8-11% of red copper fibre, 2-5% of cashew nut oil friction powder, 2-3% of graphite particle, 2-3% of calcined petroleum coke, 7-13% of barite, 3-4% of chromite, 2-3% of magnetite, 2-4% of diatomite, 7-10% of glued aluminium silicate fibre, 3-5% of flake aluminium powder, 2-4% of molybdenum disulfide, 0.2-0.5% of zinc stearate, 0.7-1% of antimony sulphide, 0.5-1% of copper sulphide, and 0.3-0.5% of tungsten carbide. After the brake pad is used, the car brake is sensitive, brake noise is low and comfort performance is good. The brake drum or brake disc has no damage in long-term use.

Description

technical field [0001] The invention relates to an automobile brake pad, in particular to a high-performance semi-metallic brake pad. Background technique [0002] Semi-metallic brake pads have high temperature control ability and high braking temperature, and the braking position is fast and accurate. Therefore, it has become one of the non-asbestos friction materials mainly promoted and applied in our country. However, in the application process of semi-metallic brake pads, many problems such as high noise, high thermal conductivity, and large damage to brake drums or brake discs have also emerged. How to make semi-metallic brake pads have low wear rate, low noise, high stability and high comfort performance is the main direction of people's current research. Contents of the invention [0003] The invention mainly solves the technical problems that the existing semi-metallic brake pads are easy to corrode, the noise is high during braking, the thermal conductivity is t...
