Abstract
The invention discloses a high-wear-resistance granule with high-temperature recession resistance function and a preparation method thereof. Raw materials of calcium carbonate whiskers, cryolite, lithopone, crystalline flake graphite, diatomite Kainafu fibers, cryolite, magnetite powder, antimony sulfide, barium sulfate and F826 adhesive are uniformly mixed, are fed in a double-roller rubber open mill for smelting, and are molten and plastified; and then, the plastified materials are crushed to particles with particle sizes of 8-20 meshes to obtain the high-wear-resistance granule with high-temperature recession resistance. The high-wear-resistance granule with high-temperature recession resistance has the following advantages: after the granule is doped in a friction piece of a brake pad by a certain ratio, the hardness and the compactness (density) of the friction piece can be effectively reduced, and the brake pad is high in wear resistance and excellent in high-temperature recession resistance.
Description
Technical field
The present invention relates to the material of friction plate in a kind of automobile brake sheet and its preparation method, particularly a kind of have anti-ageing high abrasion-proof particle material and its preparation method moving back function of high temperature.
Background technology
Breaking system is one of security system the most important on automobile, and brake facing is the parts that to have suffered in breaking system important, it can directly have influence on the reliability haveing suffered breaking system, breaking system defines friction pair by brake facing and brake flange phase mutual friction, produce braking moment, the kinetic energy of automobile is converted into heat energy, and temperature during braking can rise to 300��400 DEG C.
Conventional brake facing is divided into:
1, asbestos type, owing to fibrous magnesium silicate has high strength and high temperature resistant, therefore meets the requirement of brake facing and clutch plate, has the anti-tensile ability of fiber and the hardness of senior metal material and wear resistance simultaneously; But owing to the asbestos capacity of heat transmission is poor especially, Reusability rear brake can make heat pile up in brake facing, after brake facing heating, its braking ability will change, produce same friction and damping force can need more to step on brake number of times, if brake facing reaches certain temperature, brake failure will be caused;
2, semi-metal type, main adopts coarse Steel Wool as the big mixture of reinforced fibers and important frictional coefficient, and major advantage is to adapt to normal operation at relatively high temperatures, but noise is too big, and the wear rate of brake flange is bigger;
3, without asbestos organic type, mainly with glass fibre, aromatic polyester fiber and other fibers as reinforcement material, its performance depends primarily on type and other mixture of fiber, and advantage is without the ash fouling that falls, feature that noise is little, shortcoming be wear resistance and high temperature anti-ageing move back indifferent.
