The present invention provides a kind of brake facing for aluminium alloy frictional disk, and the liner is prepared from by the component of following quality point：Resin 15~25%；Two refining waste residues 35~55；Composite fibre 10~25；Increase grinding agent 8~15；Filler 12~20.This friction material is being braked or slowed down with aluminium alloys for automobile composite brake disk phase mutual friction, and realization ensures the purpose of traffic safety.
Description
Technical field：The present invention is a kind of suitable for automobile, is particularly suitable for use in " the brake disc of aluminium alloy car material
Or drum " used in brake strip, this friction plate belongs to " non-asbestos, without metal, without glass, non-ceramic " class of organic environmental-protection
NAO Novel friction plates.
Background technology：Brake strip is the important component of the motor vehicles such as automobile driving.Its main function is braking
Or slow down to ensure traffic safety.Therefore, its traffic safety to automobile has very important effect.It is automobile with important
Expendable parts.Also there is highly important influence to the comfortableness of the vehicles such as automobile particularly car simultaneously.
Sui continuing to develop for auto industry, according to the environmental requirement of " energy-saving and emission-reduction ", and automobile develops to lightweight to be used
The light material of body progressively substitutes traditional heavy ferrous materials into inexorable trend.See a kind of patent of invention " highway carborundum
Ceramic/aluminum alloy composite brake disk and preparation method (number of patent application：201410195034.0) ", aluminium alloy class material
Certainly it is one of inevitable direction that automobile develops to lightweight.
And the use of traditional brake strip is it cannot be guaranteed that traffic safety with al alloy disk phase mutual friction.Because antithesis material
The change of material, aluminium alloy is changed into from cast iron, and the frictional behaviour to fricting couple piece produces considerable influence, for friction material, rubs
Wiping coefficient can become very low, and weares and teares and also increase about decades of times.Though being even applied to cast iron antithesis friction material, closed with aluminium
Under the conditions of the antithesis of golden frictional disk or drum, traffic safety really cannot ensure.
The performance of friction material to being worked under the conditions of this aluminium alloy frictional disk or drum proposes new requirement, i.e.,：Rub
Wipe coefficient to stablize and higher, structural strength will it is high and it is uniform, particularly pertinent be that wearability will get well, have to selection and use one
A little new packings.And there is presently no the product for reaching this standard.
The content of the invention：
Goal of the invention：The present invention provides a kind of for brake facing of aluminium alloy frictional disk and preparation method thereof, its mesh
Be to solve traditional brake strip and the mutual friction of al alloy disk phase frictional decrease is larger, produce sternly in normal, high temperature
Weight is not wear-resisting and driving produces the phenomenons such as shake so that the problem of influenceing traffic safety.
Technical scheme：The present invention is achieved through the following technical solutions：
Brake facing for aluminium alloy frictional disk, it is characterised in that：The liner is prepared by the component of following quality point
Form：
| Title | Resin | Two refining waste residues | Composite fibre | Increase grinding agent | Filler |
| It is formulated % | 15~25 | 35~55 | 10~25 | 8~15 | 12~20 |
Composite fibre is blended with the aramid fiber slurry pool fiber and 8~15% Shenyang production organic fiber in Hai'an 2~5%；
The step of preparing the preparation method of the above-mentioned brake facing for aluminium alloy frictional disk, this method is as follows：
The present invention uses traditional production equipment, and accurately weigh various raw material by formula first adds in high speed mixer
Enter the water of amount of the mixture 35~45%, mix extremely well mixed after about 5 points, then accurately weigh compound that heat is carried out in hot-die
Pressure, temperature is 175 ± 5 DEG C, and unit pressure is that 10~12MPa is suppressed, and the time is 60-90 seconds, and in 190 DEG C of maximum temperature
It is heat-treated below 1-3 hours, then product surface is carried out to grind processing, packaging is finished product.
Advantage and effect：The present invention provides a kind of new antithesis friction that can be mutually worked with Al alloy composite brake disc
Material.This friction material is being braked or slowed down with aluminium alloys for automobile composite brake disk phase mutual friction, is realized true
Protect traffic safety.It is applied to automobile or various motor vehicles the invention provides one kind, aluminium alloy brake disc or drum are used
Brake strip.
The present invention is that a kind of resistance to elevated temperatures is good and Wear vesistance also very prominent " two refining waste residues " new material, is used as automobile
With the Main Ingredients and Appearance of brake facing.It is the brake facing that main component is made by this new material, it is small, normal with heat fading
Temperature and the coefficient of friction of high temperature are higher and steady, coefficient of friction (this still more than 0.25 when especially with 350 DEG C of high temperature
In coefficient of friction 0.25, can never can be compared with the result of cylinder iron looping test).And wear rate significantly less feature.
Known conventional brake liner production technology, the blended of use, hot pressing, heat treatment and mill processing, drilling etc.
Process is made.And the present invention is used through adding water, phenolic resin bonded material, " two refining waste residues " and increasing is set to rub and be filled out with anti-attrition class
The common mixing of material, then be made through processes such as microwave drying, hot pressing, heat treatment and mill processing, drillings.
The increasing of known brake lining rubs class filler usually with aluminum oxide, chromite powder, barite, potassium feldspar, silicon
Lime stone；Anti-attrition class materials'use is graphite, molybdenum disulfide, Liuization Antimony etc..And present invention uses the steel of Lingyuan City one
" two refining waste residues " and Jianping County real estate titanium alumina produced by Inland Steel." two refining waste residues " is will to make steel the waste residue produced through processing
Afterwards, then carry out once steel-making processing, i.e., second make steel after the waste residue that produces, then iron size-reduced, that magnetic separation proposition is contained therein
Afterwards, remaining waste residue is referred to as " two refining waste residues ".This " two refining waste residues " corrosion-free and harmfulness, but be not yet also employed, turn into
Trade waste.The main component of this " two refining waste residues " is through the detection of relevant unit of province, Contents of Main Components having more than 2%
Iron oxide, silica, zinc oxide, calcium oxide, magnesia, aluminum oxide, titanium oxide etc., and also heavy metal free class in micro content
Material.Present invention employs this " two refining waste residue ", the main increasing as brake spacer for automobile rubs filler.
Through application test, it is found that " two refining waste residues " not only there is preferably normal, high temperature section to increase the effect of rubbing, while also having
Good normal, high temperature section anti-attrition effect, is closed so it is a kind of preferable friction material that can not be common in particular for aluminium
A kind of new packing of golden mating material
Embodiment：The present invention is described further below：
The present invention provide it is a kind of be used for brake facing of aluminium alloy frictional disk and preparation method thereof, the present invention be mainly with
Increase " two refining waste residues " this new packing rubbed with anti-attrition double action, the brake for cars lining being made with preferable high temperature
Piece, its frictional behaviour achieves obvious reduction than the brake facing that the method for conventional traditional handicraft is made in wearability
Effect is fairly obvious.More than 45% can be reduced in 300 DEG C~350 DEG C section wear rates.
Brake liner slice prescription (weight ratio) of the present invention is as follows：
