The friction material is composed of synthetic fibers, magnesium oxide, aluminum oxide, barium sulfate, boron oxide, sodium bicarbonate, tert-butyl hydroquinone, ethanol and a structure enhancer. The raw materials of the friction material are matchedwith each other to prepare the friction material, the defects that the friction material has strength difference, is easy to oxidize and poor in wear resistance are improved, and the problems that the manufacturing process is complex, the consumed time is long, and the production cost is high are solved, the friction material has a special elastic effect, the performance problem of a traditionalfriction material can be changed, the wear resistance of the friction material is improved, the friction material is light in texture, environment-friendly and anti-oxidation, high pressure resistanceand material selection are achieved, and noise pollution caused by friction is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of friction materials, and in particular relates to a friction material and a preparation method thereof. Background technique [0002] Friction material is a component material used in power machinery that relies on friction to perform braking and transmission functions. It mainly includes brake linings (brake pads) and clutch facings (clutch plates). The friction material is this brake or . The key components on the transmission device, however, the existing friction materials generally have the problems of poor strength and serious noise. [0003] Automobile brake pads are the key parts of motor vehicle brakes, which are related to the safety of automobile operation, and their development is closely related to the development of automobiles. The function of the car brake pad is to absorb the kinetic energy of the car, convert the kinetic energy of the car into heat energy and other forms of energy, so ...
