Low noise brake pad and processing method thereof

Abstract

The invention relates to the technical field of automobiles, provides a low noise brake pad, and further provides a processing method of the low noise brake pad. The low noise brake pad comprises following raw materials of adhesive-sprayed aluminum silicate fiber, glass fiber, nitrile rubber powder, tire powder, cashew nut shell oil frictional powder, tung-oil-modified phenolic resin, red copper fiber, white zi stone powder, diatomaceous earth, apocynum fiber, iron oxide green, potassium feldspar, petroleum cokes, graphite, expanded perlite, floating beads, barium sulfate, boron nitride and soft magnetic materials. The low noise brake pad and the processing method thereof have the advantages that in the research process of a formula, after a large number of experiments, a reasonable combination of various components is achieved, and the advantages of each material are fully utilized in the materials, so that the raw materials can compensate each other for deficiencies of own performance, and better performance can be generated due to mutual cooperation. The low noise brake pad has a high and stable friction coefficient and a low wear rate during use, and at the same time, low noiseis achieved during braking.

Description

technical field [0001] The invention relates to the field of automobile machinery, in particular to a low-noise 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, and louder noise during braking. higher
