High-performance brake pad and production technology thereof

Abstract

The invention discloses a high-performance brake pad and a production technology thereof. The brake pad comprises the following components of, in parts by mass: 6-8 parts of phenolic resin, 2-4 partsof nitrile rubber, 8-15 parts of ceramic fiber, 5-8 parts of brass cotton, 5-8 parts of copper cotton, 3-5 parts of aramid, 10-12 parts of composite mineral fiber, 3-5 parts of vermiculite, 2-4 partsof antimony sulfide, 2-4 parts of aluminum oxide, 2-5 parts of magnesium oxide, 4-8 parts of zirconite, 8-10 parts of friction powder, 10-15 parts of graphite, 8-12 parts of coke, 8-12 parts of barite, 2-5 parts of coarse whiting and 4-6 pats of barium sulfate. A raw material A, a raw material B and a raw material C are mixed in groups and then mixed together, so that mutual coupling and complementary performance of the same group of materials are facilitated. According to the brake pad manufactured in this way, the friction coefficient can be stable in the heating and cooling processes, the wear rate is relatively low and the service life is relatively long, both the stability of braking in low-speed driving and the stability of braking in a complex driving process can be ensured and thesafety performance is improved.

Description

Technical field [0001] The invention relates to the technical field of tooth brake pad production, in particular to a high-performance brake pad and its production process. Background technique [0002] The prior art brake pads often have the following problems in the production process: all the raw materials of the brake pads are directly mixed together, because each material cannot be fully coupled, resulting in unstable performance of the final product, and the brake pads are exposed to high temperatures and complicated processes. Under conditions, surface cracks may occur, resulting in unstable or degraded braking performance. Summary of the invention [0003] In view of the above-mentioned drawbacks of the prior art, an object of the present invention is to provide a high-performance brake pad. [0004] In order to solve the above problems, the technical solution of the present invention is: a high-performance brake pad, the mass parts of each component of the brake pad are: ...

Problems solved by technology

[0002] The brake pads of the prior art often have the following problems in the production process: all the raw materials of the brake pads are directly mixed together, because each material cannot be completely and fully coupled, resulting in unstable performance of the final product. Surface cracking may occur under these conditions, resulting in unstable or reduced braking performance
