Abstract
The invention discloses a composite whisker containing granule with a strong wear resistant performance and a preparation method thereof. The preparation method comprises the following steps: evenly mixing raw materials: potassium hexatitanate whisker, calcium carbonate whisker, cryolite, lithopone, flake graphite, diatomite, and adhesive, adding the mixture into a double roller rubber open mill, carrying out melting to melt and plasticize raw materials, and finally grinding the plasticized materials into particles with a particle size of 8 to 20 meshes. The granule can be added into the friction plate of a brake pad to effectively reduce the hardness and density of friction plate; moreover, the noise generated by the brake pad can be absorbed by the friction plate, the wear resistant performance of the friction plate is improved by adding the granules, and the processed friction plate has a good high temperature resistant performance.
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 high abrasion-proof particle material containing composite crystal palpus and its preparation method.
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.
