Description
Technical field
The present invention relates to clutch friction material technical field, more particularly to a kind of calcium carbonate modified carbon nanometer of rod-like nano
Pipe modified carbon fiber enhancing paper friction material and preparation method thereof.
Background technology
In recent years, developing rapidly with automobile industry and aircraft industry, the research of friction material field also there occurs
Growth rapidly.Paper friction material is mainly used in car transmissions as the important Wet-type friction material of a class
On clutch.Coefficient of friction, friction stability, heat resistance and the wearability for how improving paper friction material are still current
The subject matter that paper friction material faces.Therefore, the interface of many scholars from material is improved between fiber and resin
Start with reference to filler systems two aspect excellent with searching out frictional behaviour, expand research.《Carbon nano-tube modification carbon fiber increases
The preparation and research of strong paper friction material》One text has prepared interfacial bonding property by adding bamboo fibre and CNT first
Preferable paper friction material.Research finds that the addition of CNT can improve the boundary of fiber and resin in material well
Face binding ability, so as to improve the frictional behaviour of material.When content of carbon nanotubes is 4wt.%, the coefficient of kinetic friction of sample
Maximum is reached, is 0.1031, now, the friction stability and anti-wear performance of sample are also preferable.Heat analysis result shows, sample
It is being heated to during 1000 DEG C, is adding sample of the mass loss than being not added with CNT of the sample of 4wt.% CNTs
Reduce 10%.Sem test result shows, in whole system, and bamboo fibre can be good at being attached on carbon fiber, change
It has been apt to the interfacial combined function between carbon fiber and resin, and CNT Preferential adsorption, on bamboo fibre, this protects bamboo again
Fiber being thermally decomposed in friction process, improves the heat resistance of sample.In order to further improve the frictional property of material
Can, we be separately added into above-mentioned system the fillers such as carborundum, boron carbide, aluminum oxide, zirconium oxide and zirconium boride and
Rare earth compound, and the relation between filer content and rare earth species etc. and sample frictional behaviour is have studied, different fillers are existed
The frictional behaviour of action mode and sample in system has carried out Primary Study.As a result show, when containing 3wt.%Ce in sample
(NO3) 3 and 15wt.% zirconium borides when, the frictional behaviour of material is optimal, and the coefficient of kinetic friction of material is 0.13285, moves/static friction
Coefficient ratio is 0.9010, and the coefficient of variation of the coefficient of kinetic friction in 500 friction processes is 0.75, and wear rate is 0.6 × 10- 8cm3J-1.Finally, have studied by filler of zirconium boride, the compression rebound of carbon nano-tube modification fibre reinforced paper friction material
Performance, heat conductivility, heat resistance and dynamic mechanical, and analyze the pass between these performances and sample frictional behaviour
System.As a result show, with the increase of boronation zirconium content, although the compression ratio and thermal conductivity factor of sample are declined slightly, still, dynamic
Mechanical test and Thermal Synthetic Analysis result show that the sample containing 15wt.% zirconium borides has higher storage modulus and heat resistance
Energy.By the research of composition-storage modulus-heat resistance-frictional behaviour relation of material, storage modulus and heat-resisting in discovery system
Performance plays a crucial role to the frictional behaviour of material, and the storage modulus of sample is bigger, and insensitivity is better, and heat resistance is got over
Good, friction stability is higher, and the wear rate of material is lower.
Friction material derived above has good performance, but the material being directly mixed to get can be easily separated so that rub
Wiping performance is unstable, and braking ability is unstable.Above-mentioned article is modified using maleic anhydride to CNT, is improved carbon and is received
The dispersiveness of mitron, can be dispersed in bamboo fibre surface, and bamboo fibre forms stable combination, but the heat resistance of bamboo fibre is also
It is not fully up to expectations, although CNT improves the heat resistance and frictional property of bamboo fibre, but in the case of heated, maleic acid
The polymer substance carbonization of acid anhydride formation, CNT is separated with bamboo fibre, influences frictional behaviour.
Addition aramid fiber can improve the frictional behaviour of friction material, but the heat resistance of aramid fiber is poor, makes it
Application in heavy load machinery receives a definite limitation.And aramid fiber surface inertia, crystallization degree are high, are combined with matrix
It is bad, it have impact on the performance of the composite of aramid fiber.Carbon fiber and bamboo fibre surface are modified with rare earth, fiber is improved
Wearability and heat resistance, but the combination of rare earth and fiber and insecure is easily separated after friction, causes changing for frictional behaviour
Become.Also need to improve the heat resistance of friction material, it is friction stability, ageing resistance, antibiotic property, toughness, static electricity resistance, wear-resisting
Other performances such as property, anti-slip, compactness, thermal conductivity.
