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 fading, poor braking effect, dust fall, noise, poor braking comfort, etc.

Abstract

The invention relates to the technical field of vehicle brake devices, in particular to a ceramic-based high-temperature-resistant brake pad and a preparation method thereof. The high-temperature-resistant brake pad is prepared from an adhesive, reinforced fibers, a friction performance modifier and filler, wherein the adhesive comprises resin and rubber powder; the reinforced fibers comprise mineral fibers, aramid fibers and potassium titanate whiskers, wherein the friction performance modifier comprises graphite, chromite powder, zirconite powder, antimony sulfide, molybdenum disulfide, tinsulfide and aluminum oxide; and the filler is barium sulfate and calcium carbonate. The ceramic-based high-temperature-resistant brake pad has the advantages of being resistant to high-temperature attenuation, high in emergency braking or high-speed braking friction coefficient, low in ash falling, low in noise, comfortable in braking, capable of meeting the environment-friendly requirement and the like.

Description

technical field [0001] The invention relates to the technical field of vehicle braking devices, in particular to a ceramic-based high-temperature resistant 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 ...
