Problems solved by technology

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 angles in the mixing, which causes the materials to be completely stirred and mixed evenly. Good materials also sink due to gravity, resulting in delamination and material precipitation, which are widely found in the industry
Existing friction materials have low strength and low coefficient of friction, and poor thermal stability when friction generates high temperature. Poor stability and not durable

Abstract

A manufacturing method of a brake pad with a good braking effect relates to the technical field of brake pad production. The brake pad comprises a friction material and steel back. The friction material comprises the following raw materials: phenolic resin, cis-polybutadiene rubber, carbon fiber resin, talcum powder, zirconium silicide, aluminium carbide, barium sulfate, graphite, molybdenum disulfide, copper silicide, steel fibre, silicon carbide whisker, aramid fiber and molybdenum fibre. The manufacturing method comprises the following steps: burdening, mixing materials by a water method, carrying out pre-press forming and primary heat treatment to produce a friction material workblank; carrying out mild heat treatment, putting the friction material workblank into scalding hot oil to undergo scaling for 3-5 s, taking the friction material workblank out and cleaning with alcohol, and airing; carrying out steel back shot-blasting, and gluing steel back; carrying out hot press molding; and successively carrying out secondary heat-treatment, grinding, slotting chamfer, sand-blasting, and gluing silent blades. The brake pad of the invention has high strength, is oxidation resistant, and has long service life, good heat stability, high friction coefficient and good environmental protection property for production.

Description

Technical field: [0001] The invention relates to the technical field of brake pad production, in particular to a brake pad with good braking effect 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 low coefficient of friction, and poor thermal stability when high temperature is generated by friction. Poor stability and not durable.
