Novel brake pad and manufacturing method thereof

Abstract

The invention discloses a novel brake pad and a manufacturing method thereof. The novel brake pad comprises a friction material and a steel backing. The friction material is prepared from, by weight, 5-12 parts of aramid pulp, 1-5 parts of aramid fibers, 5-20 parts of zirconia, 2-8 parts of graphite, 1-5 parts of petroleum coke, 0.5-4 parts of rubber powder, 2-10 parts of antimony sulfide, 5-15 parts of barite, 1-5 parts of friction powder, 5-15 parts of copper fibers, 2-10 parts of mineral fibers, 2-10 parts of mica, 5-10 parts of resin, 5-10 parts of potassium titanate and 1-8 parts of curing agent. The method includes the steps: (1) producing a friction material workblank by burdening, water mixing, prepressing for forming and primary thermal treatment; (2) subjecting the steel backing to shot blasting, and gluing the steel backing; (3) subjecting the friction material workblank and the steel backing to thermo-compression formation to obtain a brake pad workblank; (4) sequentially carrying out secondary thermal treatment, grinding, grooving, chamfering, sand blasting, silencer adhesion, accessory installation, checking, packaging and storing. High uniformity, high toughness, cleanness in production and transferring and high product uniformity are realized.

Description

Technical field: [0001] The invention relates to the technical field of brake pad production, in particular to a novel 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. In addition, if the long-diameter length of the fiber in the existing friction plate raw materials exceeds 5mm, it will be difficult to mix fully, resulting in uneven internal density of the friction plate, and the use of ...
