Abstract
The present invention relates to a kind of belong to field of material technology for New Type of Carbon carbon composite making friction material and preparation method thereof, particularly belong to carbon materials technical field.The present invention uses porous activated carbon and graphite powder to be raw material, and wherein graphite powder requires to be milled into granularity superfine powder.Raw material is poured into and kneading pot is added thereto to mid temperature pitch or liquid asphalt as binding agent after the preheated one-section time, die for molding is imported after kneading a period of time at 60 ~ 90 DEG C, send into graphitizing furnace and carry out graphitization processing, prepare New Type of Carbon carbon composite.This advanced composite material (ACM) compress under the conditions of certain pressure after resiliency, rebound rate changes with pressure size.Owing to there is a large amount of space inside it, can be used for making friction material so that it is possess elasticity, improve compressibility, reduce loss and noise, thus reach more preferable brake feel.
Description
Technical field
The present invention relates to a kind of for New Type of Carbon carbon composite making friction material and preparation method thereof, belong to material
Technical field, particularly belongs to carbon materials technical field.
Background technology
Along with developing rapidly of automobile and high ferro industry, people are to aspects such as the speed of service of vehicle, safety, comfort levels
Propose the highest demand.Friction material is as key components and parts during automobile brake, and brake noise is that user complains
One of many problems, solving noise has a lot of way, as friction plate chamfering, steel back added bloop and shockproof sheet etc., but with
Friction material abrasion in use and consumption, chamfering and bloop all can lose the effect reducing noise because of abrasion.Mesh
Before, countries in the world develop multiple friction material formulation and novel raw material the most in succession, but because technical protection, patent protection limit
Etc. many reasons, we are domestic also in space state a lot of technology.
Summary of the invention
It is an object of the invention to provide a kind of New Type of Carbon carbon composite for making friction material and preparation side thereof
Method, is that to select porous activated carbon and graphite powder be raw material, adds after binding agent kneading in kneading pot, then rolls and pressure ball,
Carrying out graphitization processing, last crushing and screening obtains.
The present invention comprises the steps:
1) raw material is chosen: selecting porous activated carbon, graphite powder is raw material；
2) kneading: weighing powder and add preheating in kneading pot, temperature controls at 60 ~ 90 DEG C；Through after a period of time, add bonding
Agent wet mixing 30 ~ 50 minutes, takes the dish out of the pot；
3) die mould: the thickener after kneading imports in casted die mould, is pressed into fine and close spheroid；
4) graphitization: the ball material suppressed is sent into graphitizing furnace, carries out graphitization processing under conditions of 2800 ~ 2900 DEG C；
5) broken, screening: the ball material after graphitization processing crushes, and uses sieved through sieve.
Further, in step 1), the particle size distribution of graphite powder is 5 ~ 10um；The ratio of activated carbon and graphite powder can basis
Rebound rate requires suitably to regulate.
Further, step 2) in binding agent be mid temperature pitch or liquid asphalt, addition is about the 30% of gross weight；Powder
Expecting that it is 10 ~ 20min that time is dry mixed, temperature controls at 60 ~ 90 DEG C；After addition Colophonium, the wet mixing time is 30 ~ 50min；
Further, casted die mould described in step 3) can be any former.
Further, in step 4), graphitization processing temperature is 2800 ~ 2900 DEG C.
The principle of the present invention is that to utilize activated carbon and small grain size graphite powder be framework material, selects mid temperature pitch or liquid drip
Blue or green as binding agent, compound is pressed into spheroid after abundant kneading, carries out graphitization processing.In graphitizing process,
Organic principle in binding agent all volatilizees, and forms a large amount of micropore.Asphalt carbonization is pitch coke, the carbon atom in pitch coke and work
Property charcoal and graphite carbon atom rely on covalent bond be closely joined together.The carbon carbon composite of this structure possesses the profit of graphite
Sliding effect, and possess abundant pore structure, resiliency after compression under the conditions of certain pressure, rebound rate becomes with pressure size
Change, can be used for making friction material, improve compressibility, reduce loss and noise, thus reach more preferable brake feel.
Concrete fabricating technology is as follows:
1) raw material is chosen: selecting porous activated carbon, graphite powder is raw material, and wherein, graphite powder Task-size Controlling is at 5 ~ 10um；
2) kneading: weighing powder and add in kneading pot and preheat, stir 20min, temperature controls at 60 ~ 90 DEG C；Through after a while
After, add binding agent wet mixing 30 ~ 50min, take the dish out of the pot；
3) die mould: the thickener after kneading imports in casted die mould, is pressed into compact texture body；
4) graphitization: the ball material suppressed feeding graphitizing furnace is carried out graphitization processing, graphitization processing temperature is 2800 ~
2900℃；
5) broken, screening: the ball material after graphitization processing crushes, and uses sieved through sieve.
The a kind of for New Type of Carbon carbon composite making friction material and preparation method thereof of present invention offer is provided.
Illustrate the concrete fabricating technology of this carbon carbon composite herein, it will help be better understood from the present invention's
Method and principle thereof.Certainly, under the premise without departing from the principles of the invention, it is also possible to by adjusting raw material granularity size, kneading
The technological parameter such as time, graphitization temperature improves, but these improve the protection domain also falling into the claims in the present invention
In.
