Automobile brake pad

Abstract

The invention discloses an automobile brake pad, and relates to the technical field of automobiles. The automobile brake pad comprises a steel sheet and a friction material layer bonded to one side of the steel sheet. The friction material layer is prepared from, by weight, 10-15 parts of nitrile rubber powder, 2-5 parts of potash feldspar powder, 20-40 parts of graphite, 2-6 parts of brown fused alumina, 1-6 parts of butyl n-butylbenzene, 0.5-2 parts of cumyl hydroperoxide, 0.5-2 parts of epoxy resin, 1-15 parts of boron phenolic resin, 1-15 parts of polypropylene, 6-10 parts of nylon powder, 5-10 parts of boron nitride, 1-2 parts of barium sulfate, 0.5-2 parts of bauxite, 0.5-2 parts of feldspar powder, 0.01-0.05 part of an accelerant and 0.01-0.05 part of an anti-aging agent. According to the automobile brake pad, the defects in the prior art can be overcome, and the automobile brake pad is free of pollution, noise and sparks, resistant to wear and long in service life.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a brake pad used in an auto brake system. Background technique [0002] Brake pads are also called brake pads or brake pads. In the braking system of a car, car brake pads are one of the most critical safety parts and play a decisive role in the braking effect. Automobile brake pads are generally composed of steel plates, adhesive insulation layers and friction blocks. The friction block is composed of friction material and adhesive. When braking, the friction block is squeezed on the brake disc or brake drum to generate friction with it, so as to achieve the purpose of decelerating and braking the vehicle. It can be seen that friction blocks determine the performance of automobile brake pads under high-speed and high-temperature braking conditions, and friction materials are an important part of automobile brake pads in the manufacturing process and use process. At present,...

AI Technical Summary

Problems solved by technology

At present, asbestos automobile brake pads are mostly used as the friction material of automobile brake pads used on vehicles, but asbestos in asbestos automobile brake pads has carcinogenic effect and has a serious impact on people's physical and mental health

When the speed of automobile brake pads reaches 300 kilometers per hour or above, the temperature after braking can easily reach more than 1000 degrees. Therefore, the brake materials are required to be resistant to high temperatures and not deformed; but the above-mentioned traditional asbestos automobile brake pads can no longer meet this requirement. At a temperature of up to 1000 degrees, it is easy to release toxic gas, has a strong smell, and is easy to deform; there are harsh noises and a large number of sparks, which pose certain safety hazards

In addition, asbestos in asbestos automobile brake pads is difficult to fully bond with other components in automobile brake pads, and it is easy to peel off, and it is not wear-resistant and has a short service life.
