Abstract

The invention provides a manufacturing method of a high-temperature-resistant brake block, and relates to the technical fields of production of brake blocks. The high-temperature-resistant brake block comprises a friction material and a steel backing, wherein the friction material comprises the following components and raw materials in parts by weight: phenolic resins, butadiene rubber, high-temperature-resistant carbon fiber resins, maleic anhydride, steel fibers, silicon carbide whiskers, aramid, molybdenum fibers, graphite, barites, silicon disulfide, copper silicide, dolomite, talcum powder, mica powder, copper powder and barium sulfate. The manufacturing method comprises the following steps of preparing the materials, mixing the materials by an aqueous method, performing prepressing forming and performing heat treatment once, so as to produce friction material blanks; performing warming treatment, putting the friction material blanks in boiling oil for scalding for 3-5 seconds, and then fishing out the scalded blanks for drying; performing shot blasting treatment on the steel backing, and spreading glue to the steel backing after the shot blasting treatment is performed; hot-forming the blanks and the steel backing; and then, sequentially performing reheat treatment, grinding, fluting, chamfering, grit blasting treatment and sticking of noisedamping sheets. The brake blocks manufactured by the method disclosed by the invention are high in intensity, oxidation-resistant, good in heat stability, high in friction coefficient, and good in production environmentally-friendly performance.

Description

Technical field: [0001] The invention relates to the technical field of brake pad production, in particular to a high temperature resistant brake pad and a manufacturing method thereof. Background technique: [0002] Brake pads are also called brake pads. In the braking system of a car, the brake pads are the most critical safety parts, and the brake pads play a decisive role in the quality of all braking effects. In the prior art, the friction pad production process of brake pads adopts dry mixing, which causes many fibers to be interrupted, and there are dead ends in the mixing, which causes the materials to be fully stirred and mixed evenly. Good materials also sink due to gravity, resulting in delamination and material precipitation, which are widespread in the industry. Existing friction materials have low strength and poor thermal stability when high temperature is generated by friction. Poor stability and not durable. Invention content: [0003] The technical pr...
