Abstract

The invention discloses a friction material, a brake pad prepared by the friction material and a preparation method of the brake pad. The preparation method of the brake pad comprises the following steps that (1) preparation of a copper-free metal friction material is performed; (2) hot-pressing molding is performed, wherein the copper-free metal friction material in the step (1) is placed in a hot-pressing mold cavity to be spread and flattened, a cushion layer material is put in the hot-pressing mold cavity to be spread and flattened, a steel backing is placed, hot-pressing molding is performed, and then demolding is performed; (3) a demolded sample undergoes heat treatment, and then is cooled to room temperature; and (4) post-treatment is performed on the sample after being treated in the step (3) to prepare the brake pad. According to the preparation method of the brake pad, the storage, transport cycle and oxidation resistance of the friction material in the brake pad can be obviously improved through rust prevention treatment.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a friction material, a brake pad prepared by using the friction material and a preparation method. Background technique [0002] Brake pads are brake pads or brake pads, which are installed on the disc brakes of automobile wheels and are one of the most critical safety components in the vehicle braking system. The advantages and disadvantages of performance such as environmental friendliness and environmental friendliness play a very important role. [0003] Common automobile brake pad friction materials are divided into two categories: metal friction materials and NAO (non-asbestos organic) friction materials, among which metal friction materials include semi-metal friction materials and metal-less friction materials, which are currently the most advanced in the world One of the main friction materials. Semi-metallic friction materials are mainly widely recognized by the No...
