Problems solved by technology

[0003] Due to the continuous development of high-performance and high-speed capabilities of vehicles, the requirements for brakes are also getting higher and higher. When the vehicle is braked during high-speed or long downhill, mountainous and other road conditions, the temperature of the friction material will rise instantaneously. Moreover, due to the need for continuous braking, the brake pads will be in a high temperature state for a long time. The increase in temperature will reduce the friction coefficient of the brake pad material, and with the increase of temperature and speed, the wear of the brake pads will be increased. Greatly shorten the life span, there are potential safety hazards

Abstract

The invention relates to the technical field of vehicle brakes, in particular to a high-temperature 500-degrees centigrade abrasion-resistant brake pad used for solving the technical problems that a brake pad is high in brake potential safety hazards in a high-speed traveling high-temperature status, meanwhile, abrasion is severe, and the service life is shortened. The brake pad comprises the following raw materials including, by weight, 10-20% of flaky titanium potassium lithium, 5-15% of zirconia, 7-10% of resin, 3-5% of copper fiber, 4-6% of mineral fiber, 2-5% of frictional powder, 1-3% ofrubber powder, 2-5% of aramid fiber, 3-5% of tin sulfide, 3-8% of carbon composite, 3-7% of calcium hydroxide, 2-4% of mica powder and the balance being barium sulfate. According to the brake pad provided by the invention, the new materials of flaky titanium potassium lithium and the zirconia are added to improve the friction material, the friction material is made to have better high-temperatureabrasion resistance, and the service life of the brake pad is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of vehicle brakes, in particular to a high-temperature 500-degree wear-resistant brake pad and a preparation method thereof. Background technique [0002] Due to the progress in the high performance and high speed capabilities of vehicles, the role of brakes is becoming more and more important, and brakes must have a sufficiently high coefficient of friction (effectiveness). In addition, since the temperature becomes high when braking at high speed, the friction state in this case is different from the case of braking at low temperature and low speed, and it is required that the change in friction coefficient due to temperature change is small, and stable friction is required nature. [0003] Due to the continuous development of high-performance and high-speed capabilities of vehicles, the requirements for brakes are also getting higher and higher. When the vehicle is braked during high-speed or long downhi...
