Wheat stalk is provided, removes the mouldy, decayed portion in described wheat stalk and remove soil therein, impurity
Generate clean wheat stalk；
Described clean wheat stalk is pulverized, after pulverizing, length is 0.1-0.2 centimetre, then carries out not in oxygen deprivation stove
Carbonization generates the wheat stalk grain of incomplete carbonization completely；
Go the removal of impurity using selecting crude drugs with winnower after the wheat stalk grain of described incomplete carbonization is activated, then carry out foaming and
Grind the described wheat stalk of generation and make friction material.
Preferably, in the temperature control that the wheat stalk grain of described incomplete carbonization is foamed at 70 to 90 degrees Celsius
Shi Fangjin foaming agent carries out foaming process.
Preferably, put when the temperature control that the wheat stalk grain of described incomplete carbonization is foamed is at 80 degrees Celsius
Enter foaming agent and carry out foaming process.
Compared to now technology, what the production technology making friction material with wheat stalk of the embodiment of the present invention made rubs

Brief description
Fig. 1 is that the process blocks of the production technology making friction material using wheat stalk of the preferred embodiment of the present invention are shown
It is intended to.
Specific embodiment
The present invention is further described for explanation and specific embodiment below in conjunction with the accompanying drawings.
Refer to refering to Fig. 1.Fig. 1 is a kind of life making friction material using wheat stalk of the preferred embodiment of the present invention
Production. art process blocks schematic diagram.
The a kind of of the embodiment of the present invention includes step using the production technology that wheat stalk makes friction material:
S1: offer wheat stalk, the mouldy, decayed portion in the described wheat stalk of removal and removal soil therein,
Impurity generates clean wheat stalk；
S2: described clean wheat stalk is pulverized, after pulverizing, length is 0.1-0.2 centimetre, then enters in oxygen deprivation stove
The incomplete carbonization of row generates the wheat stalk grain of incomplete carbonization；
In this step, wheat stalk is pulverized, after pulverizing, length is 0.1-0.2 cm, the rice wheat after pulverizing
Straw must not outdoor storage, with dryness storehouse, stock is put, and prevents absorption moisture content.The incomplete charcoal of oxygen deprivation stove is being adopted to wheat stalk
Change.From 130 DEG C to 250 DEG C, the carbonization process time is 4 hours to primary carbonization temperature, and aerator leaves 30 minutes, stops 30 minutes, totally 4
Secondary.From 250 DEG C to 350 DEG C, the heating-up time divides 6 batches to deep charring temperature, is spaced apart 1.5 hours.Argon is poured in centre.Really
Protect part keep Plant fiber original performance.
S3: go the removal of impurity using selecting crude drugs with winnower after the wheat stalk grain of described incomplete carbonization is activated, then carry out sending out
Bubble and grinding generate described wheat stalk and make friction material.
In this step, in activation furnace, with vapor to wheat stalk charcoal activation processing, increase the hole of wheat stalk charcoal
Footpath.By selecting crude drugs with winnower wheat stalk charcoal selecting crude drugs with winnower is fallen carbonization, activity after Impurity removal.
Then, wheat stalk charcoal is put in foaming furnace, temperature is put foaming agent into and carried out foaming process when being raised to 80 degree.
Finally, the formulary requirements according to friction material, grind to form the granule of various mesh numbers.
The friction materials technology index generating:
1.c 60%
2. water content is less than 1%
3. granularity 0-200 mesh
4. bulk density 0-40 mesh 1.5-1.7t/m3 40-120 mesh 1.6-2.0t/m3
120 mesh -200 1.8-2.2t/m3
5 outward appearance Lycoperdon polymorphum Vitt or black
6. the loose porous of form, graininess
Further, Celsius 70 to 90 in the temperature control that the wheat stalk grain of described incomplete carbonization is foamed
Put foaming agent when spending into and carry out foaming process.
Further it is characterised in that in the temperature control that the wheat stalk grain of described incomplete carbonization is foamed
Put foaming agent into when 80 degrees Celsius and carry out foaming process.
Compared to now technology, what the production technology making friction material with wheat stalk of the embodiment of the present invention made rubs
Wipe material and belong to sponge, have the characteristics that rough surface, loose, porous, plasticity are strong, because material surface is thick
Rough, loose, porous uses in brake block friction material, can with other materials intert, interlinkage, mutually overlapping, can be significantly
The consumption of the minimizing organic crosslinking agent of degree, can decompose and absorb the gas that organic crosslinking agent produces at high temperature simultaneously, can
Reduce crackle and the foaming that brake block occurs in process of production, effectively improve the resistance to compression impact resistance of brake block, material
Loose, porous, plasticity play adhesion enhancing action in brake block friction material, not only can adjust stablizing of coefficient of friction
Property, and have elastic well and have extraordinary anti-ageing performance to friction material.The porous performance of material, can be in brake
It is not rigid contact during piece braking, but have certain buffering, flexible and elastic, driver and crew when improve brake block brake
Comfortableness.Its porous performance can also adsorb the sound wave producing during brake block brake in a large number, reduces noise during brake block braking.
Above content is to further describe it is impossible to assert with reference to specific preferred implementation is made for the present invention
Being embodied as of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of present inventive concept, some simple deduction or replace can also be made, all should be considered as belonging to the present invention's
