Abstract

The invention discloses a wear-resistant brake pad and a processing method thereof. The wear-resistant brake pad comprises the following raw materials by weight: 3-7 parts of aramid pulp, 2.5-4.5 parts of nitrile rubber powder, 7.5-11.5 parts of cashew nut shell oil friction powder, 2-6 parts of boron phenolic resin, 3-9 parts of a corrosion resistant agent, 1.5-5.5 parts of a stabilizer, 30-50 parts of ceramic fiber, and 20-40 parts of natural cellulose fiber. The invention relates to the technical field of automobile machinery. According to the wear-resistant brake pad and the processing method thereof, by means of the aramid pulp, the nitrile rubber powder, the cashew nut shell oil friction powder and the boron phenolic resin, the grabbing force of the surface of the brake pad can be enhanced, the friction coefficient of the brake pad is stable, thermal expansion is extremely small, through cooperation of the corrosion-resistant agent and the stabilizer, corrosion of the brake pad can be relieved, the friction coefficient can be stabilized, abrasion can be reduced, and the brake pad formed by the ceramic fiber and the natural cellulose fiber is small in specific gravity, stable in friction coefficient, small in heat fading, low in noise, good in braking comfort and free of dust falling, is an environment-friendly product and is wide in application range.

Description

technical field [0001] The invention relates to the technical field of automobile machinery, in particular to a wear-resistant brake pad and a processing method thereof. Background technique [0002] Brake pads are also called brake pads; in the braking system of a car, brake pads are the most critical safety parts, and the brake pads play a decisive role in the quality of all braking effects. Earlier automobile brake pads were asbestos-type brake pads, but asbestos has been confirmed by the medical profession to be a carcinogen. Every time you brake, the brake pads will emit millions of asbestos fibers into the air, and the needle-like fibers can easily enter the lungs and stay there, causing irritation, which can eventually lead to the occurrence of lung cancer; in addition, asbestos-type There is another important problem with brake pads: because asbestos is adiabatic, its thermal conductivity is particularly poor. After repeated use, the brake will cause heat to accumul...
