Abstract
The invention discloses a kind of friction material of whisker doping, including：The mixture of high polymer binder, calcium carbonate crystal whisker and potassium titanate crystal whisker, frictional property regulator.Friction material of the present invention, by adding compound crystal whisker materials all or part alternative fiber material in the material, the friction material polishing machine for obtaining is outstanding, and occurs without heat fade scene.
Description
Technical field
The present invention relates to braking technology field, more particularly to the friction material that a kind of whisker adulterates.
Background technology
Friction material is that one kind is applied on dynamic power machine, and the part of braking and transmission agency is performed by rubbing action
Material, it mainly includes brake facing (being commonly called as brake block) and destage device dough sheet (being commonly called as clutch disc).Brake block is used to make
Dynamic, destage device piece is used to be driven.
In any plant equipment and the various vehicles for moving, it is necessary to there is braking or gearing.Friction material is this
Plant the critical piece in braking or gearing.Its main function is to absorb by rubbing or transmit power.From house device
Piece transmits power；Brake(-holder) block absorbs kinetic energy.They enable plant equipment safely and reliably to be worked with various motor vehicles.
A kind of macromolecule trielement composite material of friction material system, it is fine by high polymer binder (resin and rubber), enhancing
Peacekeeping frictional property regulator three major types component and other compounding ingredients are constituted, a series of product being made through production and processings.This
The characteristics of planting material is with good coefficient of friction and abrasion resistance properties, while also having certain heat resistance and machinery strong
Degree, can meet the performance requirement of transmission with the braking of vehicle or machinery.Be widely used in automobile, train, agri-vehicle, fly
Machine, ships, oil-well rig, mining machinery and the daily necessities such as all kinds of engineering mechanical devices and bicycle, washing machine aspect, work
It is the indispensable material of the transmission of power or braking deceleration.
Because friction material product is chronically under worst hot case at work, general organic fiber cannot bear this height
Warm condition, so majority is to apply inorfil in friction material, they include natural mineral fiber class, such as asbestos fibre, sea
Afrodite etc.；Artificial mineral wool and inorfil class, such as ceramic fibre, alumina silicate fibre, rock wool, compound mineral fiber, glass fibre
Deng；Metallic fiber class, such as steel fibre, copper fiber, aluminum fiber etc..In addition to inorfil, some organic fibers are also employed
In friction material, such as aramid fiber is belonging to high-performance, the fiber that the kind of high price is heat-resisting and tensile strength is excellent.Aramid fiber is fine
Dimension is at home and abroad in friction material industry using more, in particularly requiring performance product higher.Some other organic fiber,
There is application more as cellulose fibre, artificial organic fibre or synthetic fibers, string are also, but lacked mainly as helper component
Amount is used.
The content of the invention
It is an object of the invention to propose a kind of friction material of whisker doping, more preferable friction and abrasion is obtained in that
Energy.
It is that, up to this purpose, the present invention uses following technical scheme：
A kind of friction material of whisker doping, including：The mixing of high polymer binder, calcium carbonate crystal whisker and potassium titanate crystal whisker
Thing, frictional property regulator.
Wherein, calcium carbonate crystal whisker and potassium titanate crystal whisker are with mass ratio 2:1-1:2 ratio forms mixture.It is preferred that 1:1.
Preferably, fibrous material is also contained in the friction material of the whisker doping.
The preparation method of the friction material is prior art, and its typical but non-limiting preparating example is as follows：
All raw material components are well mixed with homogenizer, answered under the conditions of 160-180 DEG C, 22-28MPa pressure into
Type machine is compressing, then thermally treated to be obtained.
0.8-1.2 μm of the diameter of potassium titanate crystal whisker, 30~50 μm of length is and environment-friendly, with excellent mechanics and thing
Rationality energy, stable chemical performance, hardness are low, corrosion resistance, wearability, heat-resist, and the structure with tunnel-effect is its band
Come high-modulus and high intensity, the high-temperature stability and security of friction material can be improved, reduce noise.Meanwhile, with a fixed length
Footpath than physical arrangement so that potassium titanate crystal whisker can be distributed in Pin Xian areas, play strengthening action, improve the overall strong of material
Degree, improves frictional behaviour.Calcium carbonate crystal whisker also has certain draw ratio, and with special physical aspect, it is brilliant with potassium titanate
Palpus Application of composite is distributed in Pin Xian areas in friction material, plays respective distinctive appearance effect, when by external force, can rise
To the bridging effect of whisker, energy absorption plays toughening effect.
In the present invention, whisker and other materials are bonded together through binding agent, and the specific form of whisker makes whisker ask still
There is small space, in high temperature friction, the lower-molecular substance and vapor of resin pyrolytic can enter between whisker
Space, the influence for asking interface of these lower-molecular substances and vapor to brake facing and dual face is reduced, so that high
There is increasing under temperature to rub anti-attrition.Further, since the presence of whisker, is difficult to cause the macromolecular in resin and rubber to slide, make
Glass transition temperature is raised, and heat resistance is also just necessarily improved.Crystal whisker toughened is that the fracture mode of polymer is changed by brittle fracture
It is ductile rupture, by the collective effect of whisker in stress field, Anticrack makes polymer not fragile when being impacted
It is bad, once destruction can also absorb more energy to failure, material is consumed more energy during deformation, damage to destruction
Amount, therefore, it is possible to increase intensity.
Friction material of the present invention, by adding compound crystal whisker materials all or part alternative fiber material in the material
Material, the friction material polishing machine for obtaining is outstanding, and occurs without heat fade scene.
