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.
Sorghum vulgare Pers., Latin literary fame: Sorghum bicolor (L.) Moench grass family, sorghum annual herb are planted
Thing.Stalk is more sturdy, and uprightly, the upper tool of base portion joint supports root.Sheath is without hair or slightly white lead；Tip of a leaf dura mater matter, tip circle, edge has
Cilium.[1] property happiness is warm, drought resisting, waterlogging.Grain sorghum, the sugar class such as Sorghum vulgare Pers., broom sorghum can be divided into by character and purposes.
Chinese cultivated is relatively wide, is most with various places, northeast.Grain sorghum grain is edible, wine brewing.After harvesting Sorghum vulgare Pers., can produce a large amount of
By-product---sorghum 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.And containing a large amount of carbon sources in sorghum stalk, if using Sorghum vulgare Pers.
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 a kind of automotive friction material.The re-optimization of the present invention group of current friction material
Close formula, and take full advantage of the by-product of Sorghum vulgare Pers.---sorghum stalk, carried out carbonization, graphitization, made activated carbon powder,
Succedaneum as natural graphite powder joins in friction material, effectively reduces the production cost of friction material, widens Sorghum vulgare Pers.
Stalk utilize channel, improve the economic benefit of sorghum stalk.
To achieve these goals, present invention employs techniques below scheme:
A kind of automotive friction material, including the component of following parts by weight: butadiene-styrene rubber 60～70 parts, glass fibre 10～20
Part, composite fibre 10～20 parts, polypropylene 5～10 parts, silicone oil 5～10 parts, sorghum stalk activated carbon powder 10～15 parts, Pulvis Talci 5

Further illustrate, described sorghum stalk activated carbon powder be by the most cleaned for sorghum 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: sorghum 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:
1. the combination matching of composition is optimized by the automotive friction material of the present invention, has good thermostability, wearability,
No longer use asbestos component, environment protection health.
2. raw material sources are extensive, production cost is low；Take full advantage of the by-product of Sorghum vulgare Pers. plant husbandry---sorghum stalk, by it
Carrying out carbonization, graphitization, make people's activated carbon powder, the succedaneum as natural graphite powder joins in friction material, effectively drops
The low production cost of friction material, improves the economic benefit of sorghum stalk.The activated carbon powder made with sorghum stalk, can as filler
To increase the toughness of friction material, promote its performance and braking effect, stable friction factor, the noise produced when reducing friction
And it is environment friendly and pollution-free.
