Description
Technical field
The invention discloses a kind of composite brake shoes, belong to vehicle brake material technical field.
Background technology
Composite brake shoe is the important component of railway rolling stock brake system, is mainly made of steel back and friction piece,
Wherein friction piece is made of binding material, reinforcing material and friction material.The quality of composite brake shoe performance influences vehicle maintenance
Cost and traffic safety.The braking principle of composite brake shoe is cylinder iron or tiles brake block made of other materials, in braking
It holds wheel tread tightly, wheel is made to stop operating by friction.In this course, huge kinetic energy is changed by brake apparatus
Thermal energy is melt among air.And the quality of this braking effect, but depend primarily on the dissipation capability of frictional heat energy.Use this
During kind mode of braking, brake shoe friction area is small, and most of thermic load is undertaken by wheel.Train speed is higher, wheel during braking
Thermic load it is also bigger.As cylinder iron brake shoe, temperature can melt brake shoe；Even if using more advanced composite brake shoe, temperature
400~450 DEG C can be up to.When Wheel Tread Temperature increases to a certain extent, tread wear, crackle or stripping will be made, both
Influencing service life also influences traffic safety.As it can be seen that traditional tread shoe plate braking does not adapt to the needs of bullet train.
The foundation brake mode of train has friction catch, resistive braking, track eddy-current brake and regenerative braking etc., wherein with
Friction catch application is wider, it can be divided into 2 kinds of tread brake and disc braking again, the former braking member is brake shoe, and the latter is system
Dynamic disk/brake lining（Watt）Friction is secondary, and 2 kinds of modes of braking are required to that frictional force is high, brake friction material of excellent wear-resisting property.Reason
The friction material thought should have following performance：（1）Friction factor is moderate（0.3~0.5）And stablize；（2）To brake operational parameters
Sensibility it is low；（3）Heat resistanceheat resistant decline and restorability are good；（4）Enough intensity；（5）Longer service life, the attack to brake disc
Property is low；（6）Noiseless and vibration etc. during braking.With the speed-raising of train and railway freight heavy loading, to brake apparatus and braking
Material also proposed higher requirement.
Therefore, the shortcomings that how improving conventional synthesis brake shoe mechanical property and bad wear-resisting property, while it is heat-resisting to improve its
Performance is that it is promoted with applied to broader field, meeting industrial production need to obtain the composite brake shoe of more high combination property
Seek urgent problem to be solved.
Invention content
The present invention solves the technical problem of：For conventional synthesis brake shoe mechanical property, heat resistance and wearability
Can be bad the problem of, provide a kind of composite brake shoe.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of composite brake shoe is made of the raw material of following parts by weight：
20~30 parts of adhesive
Compound 80~120 parts of filler
3~5 parts of coupling agent
1~5 part of antifoaming agent
3~6 parts of curing agent
Described adhesive is made of the raw material of following parts by weight：60~80 parts of phenolic resin, 6~8 parts of Petropols, 1~3
Part terpene resin, 20~30 parts of rubber；
The compounding filler is made of the raw material of following parts by weight：20~30 parts of bat wools, 10~30 parts of nanometers
Particulate filler, 10~20 parts of nano-sheet fillers, 8~10 parts of oxidized microcrystalline waxs；
The specific preparation process of composite brake shoe is：
（1）It is formed by raw material and weighs each component；
（2）First by coupling agent and compounding filler ball milling mixing, compounding filler must be modified；
（3）Adhesive, modified compounding filler and antifoaming agent are sequentially added in batch mixer, after high-speed stirred mixing, is added solid
Agent continues to be uniformly mixed, obtains mixture；
（4）Gained mixture is injected in mold again, after hot-press solidifying molding, demoulding is modified to get composite brake shoe.
The coupling agent is any one in titanate coupling agent, silane coupling agent or aluminate coupling agent.
The antifoaming agent is silicone emulsion, any one in dimethyl silicone polymer or polyoxyethylene oxygen propyl alcohol amidogen ether.
The curing agent is that hexamethylenetetramine, isocyanates or mass fraction are any one in 60% phosphoric acid.
The phenolic resin is any one in phenolic resin 2123, phenolic resin 2127 or phenolic resin 2130.
The Petropols are any one in C5 Petropols or C9 Petropols.
The rubber is any one in natural rubber, nitrile rubber or butyl rubber.
The bat wool preparation process is：It counts in parts by weight, takes 1~3 part of nanometer iron powder, 2~5 parts of fluorinations successively
Sodium, 30~40 parts of peach gums, 100~150 parts of water are uniformly mixed, and obtain peach colloidal solution, then glass fibre and peach colloidal solution are pressed quality
Than being 1：10~1：After 15 are mixed with dipping, glass fibre is taken out, dry, charing, pyroreaction is to get bat wool.
The nanoparticle fillers are any one in nano silicon dioxide, nano zine oxide or nano-calcium carbonate.
The nano-sheet filler is nano-sheet magnesia and nano-sheet aluminium nitride is 1 in mass ratio：1 mixing and
Into.
The beneficial effects of the invention are as follows：
（1）Technical solution of the present invention is by using the filler of different-shape as system filler, in hot pressing process, filler
System surface layer can be gradually floated up to the oxidized microcrystalline wax of melting, the consistency of filler in surface layer is improved, so as to make product subsurface
Thermal conductivity and wear-resisting property effectively improve, and remainder filler is scattered in whole system, play reinforcement, toughening and
The performance of thermal conducting path is provided, so as to which the comprehensive mechanical property of product, wear-resisting property and heat resistance be made to effectively improve；
（2）Technical solution of the present invention can have by adding a small amount of Petropols and terpene resin, the addition of the two in adhesive
Effect improves adhesive to the wettability of inorganic filler, also can be in addition, oxidized microcrystalline wax and silane coupling agent are used cooperatively
Compounding filler surface forms organic clad, reduces inorganic filler surface free energy, filler is avoided to reunite, makes its fine dispersion
While in system, the compatibility that is effectively improved between filler and adhesive makes filler be filled out in system internal stability, densification
It fills, filler contacts site each other to be increased, and quick conductive access is formed inside system, so as to make system mechanical property and resistance to
Hot property is further enhanced.
Specific embodiment
