Abstract
The invention discloses a whisker-contained granule with high-temperature recession resistance function and a preparation method thereof. A formula in the method comprises Nakaifu fibers, cryolite, magnetite powder, antimony sulfide, barium sulfate, F826 adhesive and potassium hexatitanate whiskers. The preparation method comprises the following steps: the raw materials are uniformly mixed by the formula, are fed in a double-roller rubber open mill for smelting, and are molten and plastified; and finally, the plastified materials are crushed to particles with particle sizes of 8-20 meshes to obtain the composite whisker-contained granule. The hardness and the compactness (density) of a friction piece can be effectively reduced to reduce the noise generated in braking; meanwhile, the friction coefficient of the friction piece at high temperature is increased; the performance is stable; the vehicle high-temperature braking stability is guaranteed; and such problems as film transfer, environmental protection, noise and ash falling are solved.
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 high temperature anti-ageing move back function must particulate material and its preparation method containing composite crystal.
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 of whole 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, 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;
2, 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 that shortcoming is that wear resistance and heat resistance are not strong without the ash fouling that falls, feature that noise is little.
The innovative point of application novel material is to utilize crystal whisker of hexa potassium titanate in friction process to the reflex action of energy and the generation of transfer film, thus ensure the stability of brake facing frictional coefficient, conventional asbestos friction material just there will be performance degradation phenomenon when 230 DEG C, and crystal whisker of hexa potassium titanate also there will not be performance degradation phenomenon when 350 DEG C, stable frictional behaviour still can be maintained. Noise is the most insoluble problem of all friction materials manufacturers always, crystal whisker of hexa potassium titanate makes it constantly form displacement membrane due to the molecular structure of its material uniqueness, the brake facing being made up of it is not only without high frequency noise, and substantially solve the problem of low frequency noise, potassium hexatitanate stable chemical performance, nontoxic, human security can not be injured, do not pollute the environment.
