Description
Technical field
The present invention relates to the preparation method of a kind of corn stalk activated carbon powder Delanium friction material.
Background technology
Semen Maydis (Classification system: Zea mays L.) is grass family Zea annual herb plant.Another name: Semen Maydis,
Ear of maize, Semen Maydis, corn, corn, maize, maize, pearl rice, bud reed, big sorgo, Liaoning, northeast 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, the most not branch, and base portion respectively saves the raw prop root of tool gas.Leaf
Sheath tool transverse vein；Tip of a leaf film quality, blade is flat roomy, wire lanceolar, and basal circular is ear, without hair or tool defect pubescence, middle arteries and veins
Sturdy.Caryopsis is spherical or oblate spheroid, exposes outside lepicena and bran sheet after maturation, and its size produces difference with growth conditions difference.
The different flower of hermaphroditism, flowering fruit bearing stage autumn.The cultivation history of China's Semen Maydis about more than 470 year.China's sown area is 300,000,000 at present
About Mu, it is only second to paddy and wheat, in cereal crops, occupies the 3rd, be only second to the U.S. in the world.The torrid zone, the whole world and ground, temperate zone
District 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 directly to burn,
Although this mode has carried out certain utilization to it, but it is big to burn the flue dust produced, and pollutes environment to a certain extent.
At present, along with industrialized development, the usage amount of friction material is increasing, the usage amount of its filler---graphite
Also it is to increase year by year.But the price of native graphite is the highest, and containing a large amount of carbon sources in corn stalk, if using Semen Maydis
The carbon dust that stalk is made replaces graphite and adds in friction material, will greatly reduce the production cost of friction material.
Summary of the invention
It is an object of the invention to provide the preparation method of a kind of corn stalk activated carbon powder Delanium friction material.This
The bright by-product taking full advantage of Maize Industry---corn stalk, is carried out carbonization, graphitization, makes artificial graphite material, makees
Succedaneum for natural graphite powder joins in friction material, effectively reduces the production cost of friction material, widens corn stalk
Utilize channel, improve the economic benefit of corn stalk.
To achieve these goals, present invention employs techniques below scheme:
The preparation method of a kind of corn stalk activated carbon powder Delanium friction material, comprises the following steps:
Step one, collects new harvesting or the corn stalk in semiannual period, removes corn stalk mouldy, that rot, cleans up, then put
Enter dehydrator carry out drying to corn stalk water content be 10%；Dry temperature and be set to 40 DEG C；
Step 2, the corn stalk after drying is ground into the corn stalk powder that particle diameter is 0.5mm；Then corn stalk powder is put into mould
In, it is pressed into corn stalk block；
Step 3, puts into oxygen deprivation stove by corn stalk block and carries out carbonization treatment；The humidity discharging phase rises to 150 DEG C from igniting to furnace temperature, time
Between be 5 hours；Then heating to 250 DEG C, open aerator, to air blast in stove, the primary carbided time is 4 hours, and aerator leaves
30 minutes, stop 30 minutes, circulate 4 times；Being warming up to 500 DEG C, the heating-up time is 2 hours, and after temperature rises to 500 DEG C, insulation 2 is little
Time, then it is warming up to 650 DEG C, the heating-up time is 4 hours, and when being warming up to 650 DEG C, aerator leaves 1 hour, stops 1 hour, circulates 2 times,
It is warming up to 850 DEG C again, after 1 hour, opens ventilation blower, send into air and water vapour, progressively cool down, generate carbon, go out after 6 hours
Stove；
Step 4, puts in graphitizing furnace after the carbon cooling after coming out of the stove, carries out graphitization processing；First with the speed of 2 DEG C/min
Degree is warming up to 350 DEG C, pressurising 4MPa, then heats up 550 DEG C with the speed of 1 DEG C/min, is incubated 2 hours, then rises under argon shield
Temperature carries out graphitization to 2500 DEG C, then naturally cools to room temperature；
Step 5, is broken into fine particle by the carbon dust after graphitization, is subsequently adding the mica powder of 5%, after uniform stirring, regrinds
Make the powder of 200 mesh, weigh, pack, i.e. obtain Delanium friction material finished product.
Advantages of the present invention:
Raw material sources are extensive, preparation technology simple possible；Take full advantage of the by-product of corn planting industry---corn stalk, by it
Carrying out carbonization, graphitization, make artificial graphite material, the succedaneum as natural graphite powder joins in friction material, effectively
Reduce the production cost of friction material, improve the economic benefit of corn stalk.With the artificial graphite material that corn stalk is made it is
Filler, can increase the toughness of friction material, promotes its performance and braking effect, stable friction factor, produces when reducing friction
Raw noise and environment friendly and pollution-free.
