Description
Technical field
The present invention relates to a kind of friction material, particularly relate to a kind of friction material for vehicle brake-holder block and application thereof.
Background technique
Friction material is that one is applied on dynamic power machine, relies on rubbing action to perform the component materials of braking and transmission agency.It mainly comprises brake facing (brake block) and clutch surface (clutch plate).Brake block is used for braking, and clutch plate is used for transmission.The various vehicles of any machinery and motion all must have to be braked or transmission device.Friction material is the critical piece on this braking or transmission device.Its topmost function absorbs or transferring power by rubbing.As clutch plate transferring power, braking plate absorbs kinetic energy.They enable machinery and various motor vehicle work safely and reliably.Friction material is that one is widely used and very crucially material thus.
The friction material of current industry belongs to macromolecule trielement composite material, and it comprises three parts: with polymeric compound be Bond, with inorganic or organic fiber be strengthen component, be frictional property regulator or compounding ingredient with filler.
1 Bond: friction material organic binder used is phenolic resinoid and synthetic rubber, and based on phenolic resinoid.Their feature and effect first then enter viscous state in softening when being under certain heating-up temperature, produce and flow and be uniformly distributed the matrix forming material in the material, finally by the vulcanization of resin solidification effect, fiber and filler are bonded together, and what form quality densification has suitable intensity and can meet the friction plate goods that friction material usability requires.
For friction material, the heat resistance of resin and rubber is very important performance index.Because vehicle and machinery are when carrying out braking and transmission work, under friction plate is in the worst hot case condition of 200 DEG C ~ about 450 DEG C.In this temperature range, the major component of fiber and filler is inorganic type, thermolysis can not occur.And for resin and rubber, organic, enter again thermolysis region.The property indices of friction material is now many can there is disadvantageous change (friction factor, wearing and tearing, mechanical strength etc.), particularly friction material is detecting and three heat (heat fade, thermal expansion, the heat crack) phenomenon that occurs in using process, and its root is all cause due to the thermolysis of resin and rubber, organic.Therefore resin and the performance of rubber to friction material is selected to have very important effect.Select different Bonds will draw different frictional behaviours and structural behaviour.Current use phenolic resin and modified resin thereof.As: cashew nut oil modified, butyronitrile powder modification, modified rubber and other phenol-formaldehyde resin modified are as the Bond of friction material.
To the quality requirement of resin be:
(1) good heat resistance, has good heat decomposition temperature and lower thermal weight loss.
(2) powdered resin fineness wants high, is generally 100 order ~ 200 orders, preferably more than 200 orders, is conducive to the uniformity of batch mixing dispersion, can reduces the consumption of resin in formula.
(3) free phenol content is low, is advisable with 1% ~ 3%.
(4) suitable curing rate 40s ~ 60s (150 DEG C) and flow distance (120 DEG C of 40 ~ 80mm).
2 reinforcing fibers: fibre reinforced materials forms the base material of friction material, its gives friction goods enough mechanical strength, can bear the impact force, shearing force, the pressure that produce due to braking and transmission in the load forces of friction plate grinding in process of production and riveted joint processing and using process.
China's related standards and automobile factory, according to the actual applying working condition condition of friction plate, propose corresponding requirement of mechanical strength to friction plate.As: impact strength, resistance to flexure, compressive strength, shear strength etc.In order to meet these strong performance requirements, need to select suitable fiber species to increase, meet strength character.
Friction material requires its fiber fraction used:
(1) strengthen effective.
(2) good heat resistance.Can not fuse at friction operation temperature, carbonization and thermolysis phenomenon.
(3) there is basic friction factor.
(4) hardness is unsuitable too high, in order to avoid produce brake noise and damage brake disc or drum.
(5) process operability is good.
3 fillers: the filler in friction material constituents, are mainly made up of frictional property regulator and compounding ingredient.Use the object of filler, mainly contain the following aspects:
(1) regulate and improve the frictional behaviour of goods, physical property and mechanical strength.
(2) control goods thermal expansion coefficient, thermal conductivity, shrinkage, increase the stability of product size.
(3) brake noise of goods is improved.
(4) manufacturing process performance and the processibility of goods is improved.
(5) products appearance quality and density is improved.
(6) cost of production is reduced.
When the formula Design of friction material, select the performance that filler must understand filler and the effect played in the various characteristics of friction material.Proper use of filler determines the performance of friction material, manufacturing process is also very important.
According to the effect of frictional property regulator in friction material, " increasing mill filler " and " anti-attrition filler " two classes can be divided into.Friction material itself belongs to friction resistance material, and for performing braking and transmission agency requires to have higher friction factor, therefore the increasing filler that rubs is the main component of frictional property regulator.The increasing effect of rubbing of different filler is different.
The Mohs hardness increasing the filler that rubs is generally 3 ~ 9.The increasing that hardness the is high Be very effective that rubs is obvious.Fillers more than 5.5 hardness belongs to hard filler, but will control its consumption, granularity.(as aluminium oxide, zircon etc.)
Anti-attrition filler: be generally low hardness material, lower than the mineral of Mohs hardness 2.As: graphite, molybdenum disulfide, French chalk, mica etc.It can reduce the wearing and tearing that friction factor can reduce again mating material, thus improves the working life of friction material.
Friction material is a kind of special material worked in heat with the environment of elevated pressures, and therefore just require that filler composition used must have good heat resistance, i.e. thermostability, comprises ermal physics effect and thermochemistry effect etc.
The packing density of filler is very large to the performance impact of friction material.The different performance requirement of friction material is also different to the requirement of the packing density of filler.
Current friction material manufacturing process is complicated, requires high, and then cause cost high to the component property of material; And the general friction material of industry adopts is all the intrinsic colour of material, resolution is not high.
