Above description is only the general introduction of technical solution of the present invention, in order to better understand the technical means of the present invention,
And can be implemented in accordance with the contents of the specification, and in order to allow above and other objects of the present invention, feature and advantage can
It is clearer and more comprehensible, below the special specific implementation mode for lifting the present invention.
Description of the drawings
By reading the detailed description of hereafter preferred embodiment, various other advantages and benefit are common for this field
Technical staff will become clear.Attached drawing only for the purpose of illustrating preferred embodiments, and is not considered as to the present invention
Limitation.And throughout the drawings, the same reference numbers will be used to refer to the same parts.In the accompanying drawings：
Fig. 1 shows the flow chart according to preparation method proposed by the present invention.
Specific implementation mode
The exemplary embodiment of the disclosure is more fully described below with reference to accompanying drawings.Although showing the disclosure in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
Completely it is communicated to those skilled in the art.
One aspect of the present invention provides a kind of friction material, and the friction material is with potassium titanate fibre for main strengthening material
Material, using special cermacis fiber as auxiliary reinforcement.The friction material is with potassium titanate fibre (K2O8TiO2) it is main strengthening material
Material, using special cermacis fiber as a kind of friction material that composite fibre base is enhanced of auxiliary reinforcement.
The friction material does not contain any asbestos ingredients and iron powder, steel wool metalloid material, and product has complete ring
It supports value value.The high intensity that has using potassium titanate itself, high abrasion, lightweight, difficult meltbility and special cermacis fiber spy high temperature resistant,
The characteristic that strong adsorption, high-temperature stability are strong, easily disperse forms more stable main enhancing framework material.By relatively simple
And maneuverable production technology can be solved the shortcomings that traditional ceramics fiber prescription is not easy dispersion, general common batch mixer
And mixing procedure can reach uniformly mixed effect.
Since friction material proposed by the present invention does not contain any metal material, and melted using the infusibility of potassium titanate fibre
It is Nian Jie with backboard due to wet environment to eliminate material with brake disc corrosion phenomena for the working face that property has thoroughly eradicated friction material
Rust leaching flake and the flake phenomenon that occurs.
The friction material further includes cashew nut oil modified resin and organic matter friction particles, the cashew nut oil modified resin with have
Machine object friction particles mix to soak with potassium titanate fibre and close.Pass through cashew nut oil modified resin and the same metatitanic acid of organic matter friction particles material
Potassium fiber mixes to soak and close, and becoming sticking friction using abrasive material fretting wear wears, and average life span reaches ten thousand kilometers of 6-8, relatively passes
The semimetal formula of system improves 100% and 50% with ceramic formula.
The friction material further includes the antimony class sulfide as bonding agent.By the way that antimony class sulfide is added as friction material
Secondary bonding agent, change previous semimetal formula and single ceramic fibre formula need it is cured above in 240 degree of high temperature
Disadvantage, only need to the heat treatment degree between 200 degree to 220 degree of high temperature be can reach stable high temperature friction material property (
In high temperature decline, 450 degree of high temperature friction coefficients are up to 0.35 or more) and stable physical properties (compression ratio is less than 2%,
3%) coefficient of thermal expansion is less than.Process risk rate of the friction material in high-temperature heat treatment process is reduced, production technology is simplified,
Improve production efficiency.Improve the mechanism of the abrasive wear of traditional semimetal formula and ceramic formula.
As a kind of specific implementation mode, the friction material is according to weight ratio, including potassium titanate fibre 8-15%, Special clay
Porcelain fiber 10-20%, cashew nut oil modified resin 6-10%, organic matter friction particles material 4-8%, antimony class sulfide 3-8% are high
Pure graphite 3-8%, other filler 30-50%.Friction material product shear strength proposed by the present invention is high, abrasion-resistant.
The present invention also provides a kind of vehicle brake-holder block, which is made of foregoing friction material.One
Kind clutch disc, is made of foregoing friction material.
Due to manufacturing the friction material of the vehicle brake-holder block due to not containing any metal material, and utilization potassium titanate fibre
The difficult meltbility of dimension has thoroughly eradicated the working face of friction material with brake disc corrosion phenomena, eliminate material it is Nian Jie with backboard because
Wet environment and become rusty leaching flake occur flake phenomenon.
The present invention also provides a kind of methods preparing friction material noted earlier, as shown in Figure 1, this method includes：
S1. cashew nut oil modified resin and organic matter friction particles material is added, is allowed to mix to soak with potassium titanate fibre to close；
S2. the potassium titanate fibre after utilizing batch mixer to close leaching by mixing procedure is uniformly mixed with special cermacis fiber；
S3. it is heat-treated after antimony class sulfide being added.
This method changes previous semimetal formula by the way that antimony class sulfide is added as the secondary bonding agent of friction material
It is needed in 240 degree of disadvantages cured above of high temperature with single ceramic fibre formula, it only need to be between 200 degree to 220 degree of high temperature
Heat treatment degree i.e. can reach stable high temperature friction material property.
Friction material is reduced in high-temperature heat treatment due to reducing heat treatment temperature using method proposed by the present invention
Process risk rate in the process, and production technology is simplified, improve production efficiency.
The present invention proposes new friction material, improves traditional semimetal formula and ceramic formula, changes abrasive material mill
The mechanism of damage becomes sticking friction using abrasive material fretting wear and wears.
Titanium Tao Ji automobile brake linings proposed by the present invention are increased using the mixing of special cermacis fiber and potassium titanate fibre
By force, and using the difficult meltbility of potassium titanate fibre, the shear strength of product is substantially increased.Pass through cashew nut oil modified resin
It is closed using its proportioning with the molten leaching of packet of special cermacis fiber and potassium titanate fibre with organic matter friction particles material, changes tradition
The abrasive material frottage of friction material, abrasion mechanism become adhere frottage, abrasion mechanism.By be added antimony class sulfide as
The secondary bonding agent of friction material stabilizes the frictional behaviour of product, drops by replacing traditional crystalline flake graphite with high purity graphite
The abrasion of low product.
In the instructions provided here, numerous specific details are set forth.It is to be appreciated, however, that the implementation of the present invention
Example can be put into practice without these specific details.In some instances, well known method, structure is not been shown in detail
