Description
Technical field
The present invention relates to the preparation method of a kind of function admirable modified friction material.
Background technology
Friction material is widely used in various transport facility (such as automobile, train, aircraft etc.) and various plant equipment
Brake, clutch and friction gearing in brake material.It is broadly divided into brake liner by the position of function and installation
Sheet and clutch surface.Friction material belongs to crucial safety member in the automotive industry, the startup of automobile, braking and parking all from
Not opening friction material, the quality of friction material, quality can the people's lives and property safety by direct relation, and its function status is not sayed
And explain.But traditional Automotive Friction Material exists some defects, such as asbestos Automotive Friction Material, because asbestos are a kind of natural
Mineral fibres, it has higher thermostability and mechanical strength, but asbestos have certain danger to health.Because of this person
The friction material without asbestos that begins one's study, the component formula of friction material is adjusted, improves, select composite fibre
Or metallic fiber etc..
It addition, 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, people also begin to the succedaneum to native graphite and carry out
Further investigation.
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 process
Mode is directly to burn, although this mode has carried out certain utilization to it, but it is big, to a certain degree to burn the flue dust produced
Upper pollution environment.And containing a large amount of carbon sources in corn stalk, if the carbon dust using corn stalk to make replaces graphite adds friction to
In material, the production cost of friction material will be greatly reduced.
Summary of the invention
It is an object of the invention to provide the preparation method of a kind of function admirable modified friction material.Re-optimization of the present invention
The combination formula of current friction material, and take full advantage of the by-product of Semen Maydis---corn stalk, carried out carbonization, stone
Mo Hua, makes activated carbon powder, and the succedaneum as natural graphite powder joins in friction material, effectively reduces friction material
Production cost, that widens corn stalk utilizes channel, improves the economic benefit of corn stalk.
To achieve these goals, present invention employs techniques below scheme:
The preparation method of a kind of function admirable modified friction material, comprises the following steps:
Step one, weighs raw material components in following parts by weight ratio: isoprene rubber 60～70 parts, glass fibre 10～20 parts,
Composite fibre 10～20 parts, polypropylene 5～10 parts, silicone oil 5～10 parts, corn stalk activated carbon powder 10～15 parts, Pulvis Talci 5～10
Part, molybdenum bisuphide 5～10 parts, fire retardant 2～5 parts and three vanadium oxides 1～2 parts；
Step 2, puts into the above-mentioned raw material components weighed successively in blender, is sufficiently stirred for, and after mix homogeneously, takes out
Dry；
Step 3, is put into mould on vulcanizing press, preheats mould, treats that temperature rises to 100 DEG C, equal at film intracavity
Even smearing release agent, is subsequently adding the raw material after step 2 processes, carries out hot-forming, and temperature is 250 DEG C, adds in mould
Pressure, raises 5MPa, is that pressure rises to 25MPa from 5MPa, and venting per minute is once, last pressurize 10 minutes for every 5 minutes, de-
Mould obtains thick embryo；
Step 4, puts into the thick embryo that step 3 obtains and carries out post processing in baking oven, and temperature is 200 DEG C, and the time is 12 hours,
Take out natural cooling, cutting forming, i.e. obtain function admirable modified friction material finished product.
Further illustrate, described corn stalk activated carbon powder be by the most cleaned for corn stalk drying, pulverize briquet,
The carbon dust obtained after carbonization treatment, graphitization processing.
Further illustrating, described carbonization treatment carries out carbonization treatment particularly as follows: corn stalk block is put into oxygen deprivation stove；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；Being warming up to 500 DEG C, the heating-up time is 2 little
Time, after temperature rises to 500 DEG C, it being incubated 2 hours, then be 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 illustrating, described graphitization processing, particularly as follows: put in graphitizing furnace after the carbon cooling after coming out of the stove, is entered
Row graphitization processing；First it is warming up to 350 DEG C with the speed of 2 DEG C/min, pressurising 4MPa, then heat up with the speed of 1 DEG C/min
550 DEG C, it is incubated 2 hours, then under argon shield, is warming up to 2500 DEG C carries out graphitization, then naturally cool to room temperature, then grind
Make the carbon dust of 200 mesh.
Fire retardant in the present invention uses the aluminium hydroxide type fire retardant generally sold on market.Add a small amount of
Three vanadium oxides can effectively improve the intensity of friction material.
Advantages of the present invention:
Raw material sources the most of the present invention are extensive, preparation technology simple possible, production cost are low；Function admirable modified friction material is become
Point combination matching be optimized, there is good thermostability, wearability, no longer use asbestos component, environment protection health.
2. take full advantage of the by-product of corn planting industry---corn stalk, carried out carbonization, graphitization, make people and live
Property powdered carbon, the succedaneum as natural graphite powder joins in friction material, effectively reduces the production cost of friction material, carries
The high economic benefit of corn stalk.The activated carbon powder made with corn stalk, as filler, can increase the toughness of friction material, promotes
Its performance and braking effect, stable friction factor, the noise produced when reducing friction and environment friendly and pollution-free.
