Wear-resisting brake pad and machining method thereof

Abstract

The invention relates to the mechanical field of automobiles, and provides a wear-resisting brake pad. The wear-resisting brake pad is prepared from aramid pulp, viscose, nitrile rubber powder, tire powder, cashew nut shell oil friction powder, tung oil-modified phenolic resin, red copper fiber, white Zi stone powder, stainless steel short fiber, apocynum venetum fiber, iron oxide green, potassiumfeldspar, petroleum coke, graphite, expanded perlite, paper fiber, barium sulfate, zirconium oxide and soft magnetic materials. The invention further provides a machining method of the wear-resistingbrake pad. The wear-resisting brake pad has the advantages that in the research process of the formula, through a large number of experiments, multiple ingredients are reasonably matched, it is ensured that the advantages of all the materials are brought into full play, the raw materials can mutually compensate for defects of properties and can also produce better properties due to mutual matching, and the wear-resisting brake pad has high and stable friction coefficients and the low wear rate in the using process.

Description

technical field [0001] The invention relates to the 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, the brake pads are the most critical safety parts, and the brake pads play a decisive role in the quality of all braking effects. [0003] 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.

Problems solved by technology

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 accumulate in the brake pads. After the brake pads become hot, their braking performance will decrease. Changes, to produce the same friction and braking force will require more times to step on the brakes, if the brake pads reach a certain temperature, it will cause brake failure

However, the formula design of some semi-metallic brake pads often has a certain degree of blindness, which causes some inherent shortcomings of semi-metallic brake pads to be magnified, such as greater damage to the brake drum or brake disc.
