Abstract

The invention discloses a brake pad and belongs to the technical field of automobile spare parts. The brake pad is prepared from the following materials, by mass: 20 parts of organosilicone modified phenolic resin, 3-10 parts of aramid fiber, 1-2 parts of tire powder, 4-6 parts of heavy magnesium oxide, 8-10 parts of ceramic fiber, 2-4.5 parts of ferrochromium mineral powder, 2-6 parts of brown aluminum oxide, 2-4 parts of antimony sulfide, 12-18 parts of potassium titanate, 10-15 parts of barite, 8-10 parts of boron containing phenolic resin, 10-15 parts of calcium sulfate whiskers, 4-6 partsof flake graphite, 6-8 parts of cashew nut oil friction powder, 4-7 parts of calcined petroleum coke, 4.5-6.5 parts of flake aluminum powder, 0.2-0.7 part of red copper fiber and 0.2-0.5 part of black silicon carbide. The abrasion resisting performance is excellent, the content of heavy metal matter is very low, the brake pad is very environmentally friendly, and the advantages of the materials are given full play to in the friction material. Meanwhile, in the using process, an excellent friction layer and a transfer membrane can be formed, the service life is long, the friction coefficient is stable, braking is stable, and the comfortable capability is good.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a brake pad. Background technique [0002] Brake pads are an indispensable part of a car, both a safety part and a vulnerable part. It is usually required to be wear-resistant, have a large friction coefficient, and have excellent heat insulation properties. Most of the friction materials currently used in automobile brake pads contain more heavy metals, including copper, chromium, cadmium, and lead metals. Every time a car brakes, a small amount of heavy metal dust is released and accumulated in the environment, causing harm. Therefore, it is necessary to find safer, more effective and environmentally friendly friction materials to replace heavy metals such as copper on the premise of ensuring the performance of brake pads. Contents of the invention [0003] The object of the present invention is to provide a brake pad to solve the problem that the existing brake pads co...
