Abstract

The invention discloses particles having noise reduction and high-temperature declining resistance functions and a preparation method of the particles. A formula adopted in the method comprises 12 parts of NACF fibers by weight, 10 parts of spherical white vermiculite by weight, 12 parts of hollow aluminium silicate spheres by weight, 7 parts of cryolite by weight, 15 parts of magnetite powder by weight, 1 part of butadiene-acrylonitrile rubber powder by weight, 1 part of antimony sulfide by weight, 7 parts of barium sulfate by weight and 8 parts of an F826 adhesive by weight. A preparation technology of the particles comprises steps as follows: raw materials are evenly mixed as per the formula and placed into a double-roll rubber open mill for smelting, the raw materials are fused and plasticized, finally, plasticized materials are crushed to form particles with the particle size ranging from 8 meshes to 20 meshes, and the particles are obtained. The particles have the good sound absorption characteristic, the hardness and the compactness of friction plates can be effectively reduced, the friction plates absorb produced noise during working, the heat fading performance of the friction plates is improved, the friction coefficient of the friction plates at the high temperature is increased, and the high-temperature brake stability of automobiles is guaranteed.

Description

technical field [0001] The invention relates to a material for a friction plate in an automobile brake pad and a preparation method thereof, in particular to a granular material with noise reduction and high temperature anti-decay functions and a preparation method thereof. Background technique [0002] The braking system is one of the most important safety systems on a car, and the brake pad is an important part of the entire braking system, which will directly affect the reliability of the entire braking system. The discs rub against each other to form a frictional couple, which generates braking torque and converts the kinetic energy of the car into heat energy. The temperature during braking will rise to 300-400°C. [0003] Conventional brake pads are divided into: [0004] 1. The semi-metal type mainly uses rough steel wool as a mixture of reinforcing fibers and important friction coefficients. The main advantage is that it can adapt to normal work at higher temperatur...
