AI Technical Summary

Problems solved by technology

Among them, semi / low metal brake pads have good braking performance, but have more dust and noise, and poor braking comfort; ceramic brake pads have good dust and noise performance, but slightly poor braking performance, and the temperature is higher than 350 °C When the temperature is high, it is easy to produce high temperature recession, which affects driving safety
In summary, semi / low metal base and ceramic base have disadvantages such as high temperature decay, poor braking effect, more dust, loud noise, poor braking comfort, and short service life.

Abstract

The invention relates to the technical field of vehicle braking devices, and in particular relates to a high-wear-resistance and low-metal brake pad and a preparation method of the high-wear-resistance and low-metal brake pad. The high-wear-resistance and low-metal brake pad is prepared from a binder, reinforced fibers, a friction performance regulator and a filler, wherein the binder comprises resin and rubber powder; the reinforced fibers comprise aramid fibers and steel wool fibers; the friction performance regulator comprises magnesium oxide, antimony sulfide, aluminum oxide and reduced iron powder; and the filler is barium sulfate and calcium carbonate. The high-wear-resistance and low-metal brake pad has the advantages of being resistant to high-temperature recession, high in friction coefficient during emergency braking or high-speed braking, low in dust and noise, long in service life, comfortable in braking, capable of meeting the environmental protection requirement and the like.

Description

technical field [0001] The invention relates to the technical field of vehicle braking devices, in particular to a high-wear-resistant and low-metal brake pad and a preparation method thereof. Background technique [0002] With the rapid development of my country's automobile industry, the requirements for automobile speed and performance are getting higher and higher. At the same time, higher requirements are also put forward for automobile braking technology. Brake pads are crucial safety parts in the braking process of automobiles, and their performance directly determines the braking performance of automobiles, which is related to the driving safety of every automobile. Now that the speed of the car is high, the temperature of the brake pads and brake discs is as high as 600-700°C during continuous or emergency braking, which puts forward very high requirements for the high temperature resistance of the brake pads. At present, the friction coefficient of most of the bra...
