Abstract
The invention discloses an active carbon powder for a frictional material. The active carbon powder is mainly prepared from the following components by weight: 80 to 90 parts of corn stalk carbon powder, 5 to 10 parts of mica powder and 5 to 10 parts of molybdenum disulfide. The corn stalk carbon powder is carbon powder obtained by subjecting corn stalk to cleaning and drying, crushing and briquetting, carbonization and graphitization successively. The modified filling material makes full use of a by-product of corn, i.e., corn stalk; the corn stalk undergoes carbonization and graphitization so as to obtain active carbon powder which is used as a substitute of natural graphite powder and added into the frictional material; so the production cost of the frictional material is reduced, the utilization scope of the corn stalk is broadened, and the economic benefits of the corn stalk are increased.
Description
Technical field
The present invention relates to a kind of activated carbon powder of friction material.
Background technology
Semen Maydiss（Classification system：Zea mays L.）It is grass family Zea annual herb plant.Another name：Semen Maydiss,
Ear of maize, Semen Maydis, corn, corn, maize, maize, pearl rice, luxuriant reed, big sorgo, northeast Liaoning words claim pearl grain, and Teochew claims
SEMEN COICIS, Guangdong language is referred to as Semen setariae, and the south of Fujian Province language is referred to as kind wheat.Stalk is upright, generally not branch, and base portion respectively saves tool gas and gives birth to prop root.Leaf
Sheath has transverse vein；Tip of a leaf film quality, blade is flat roomy, wire lanceolar, and basal circular is in ear, no hair or tool defect pubescence, middle arteries
Sturdy.Caryopsis is spherical or oblate spheroid, exposes outside lepicena and bran piece after maturation, and its size produces difference with growth conditionss are different.
The different flower of hermaphroditism, flowering fruit bearing stage autumn.The cultivation history of China's Semen Maydiss is about more than 470 year.At present China's sown area is 300,000,000
About mu, it is only second to paddy and wheat, occupy the 3rd in cereal crops, be only second to the U.S. in the world.The whole world torrid zone and temperate zone ground
Area extensively plants, and is an important corn.
After harvesting corn, substantial amounts of by-product can be produced --- corn stalk.Generally people's processing mode is direct burning,
Although this mode has carried out certain utilization to it, burn the flue dust producing greatly, pollute environment to a certain extent.
At present, with industrialized development, the usage amount of friction material is increasing, the usage amount of its filler --- graphite
It is also to increase year by year.But the price of native graphite is still higher, and contain a large amount of carbon sources in corn stalk, if adopting Semen Maydiss
The carbon dust that stalk is made replaces graphite and is added in friction material, will greatly reduce the production cost of friction material.
Content of the invention
It is an object of the invention to provide a kind of activated carbon powder of friction material.The present invention takes full advantage of the pair of Semen Maydiss
Product --- corn stalk, is carried out carbonization, graphitization, makes activated carbon powder, and the succedaneum as natural graphite powder is added to and rubs
Wipe in material, effectively reduce the production cost of friction material, widen the utilization channel of corn stalk, improve the economy of corn stalk
Benefit.
To achieve these goals, present invention employs technical scheme below：

As present invention further optimization scheme, the activated carbon powder of this friction material is mainly by following parts by weight
Component is formulated：85 parts of corn stalk carbon dust, 8 parts of mica powder and 7 parts of molybdenum bisuphide.
Further illustrate, described corn stalk carbon dust is by corn stalk successively cleaned drying, pulverizes briquet, carbonization
The carbon dust obtaining after process, graphitization processing.
Further illustrate, described carbonization treatment is specially：Corn stalk block is put into oxygen deprivation stove and carries out carbonization treatment；Humidity discharging
Phase rises to 150 DEG C from igniting to furnace temperature, and the time is 5 hours；Then heat to 250 DEG C, open aerator, to air blast in stove,
The primary carbided time is 4 hours, and aerator leaves 30 minutes, stops 30 minutes, circulates 4 times；It is warming up to 500 DEG C, the heating-up time is little for 2
When, after temperature rises to 500 DEG C, it is incubated 2 hours, then is warming up to 650 DEG C, the heating-up time is 4 hours, when being warming up to 650 DEG C, air blast
Machine leaves 1 hour, stops 1 hour, circulates 2 times, then is warming up to 850 DEG C, after 1 hour, opens ventilation blower, sends into air and water vapour,
Progressively cool down, generate carbon, come out of the stove after 6 hours.
Further illustrate, described graphitization processing is specially：Put in graphitizing furnace after the carbon cooling after coming out of the stove, enter
Row graphitization processing；It is warming up to 350 DEG C with 2 DEG C/min of speed first, pressurising 4MPa, then heated up with 1 DEG C/min of speed
550 DEG C, it is incubated 2 hours, then is warming up to 2500 DEG C under argon protection and carry out graphitization, then naturally cool to room temperature, then grind
Make the carbon dust of 200 mesh.
Advantages of the present invention：
Raw material sources are extensive, preparation process is simple is feasible；Take full advantage of the by-product of Semen Maydiss --- corn stalk, carried out carbon
Change, graphitization, make carbon dust, the succedaneum as natural graphite powder is added in friction material, effectively reduces friction material
The production cost of material, improves the economic benefit of corn stalk.The activated carbon powder made with corn stalk, as filler, can increase friction
The toughness of material, lifts its performance and braking effect, stable friction factor, reduces the noise producing during friction and environmental protection is no dirty
Dye.
