Description
Technical field
The invention belongs to Corii Bovis seu Bubali Material Field, particularly to the making of a kind of Modified Kraft friction material fiber
Method.
Background technology
After Corii Bovis seu Bubali goods are shabby, people typically abandon as rubbish, then carry out burning disposal, so
Not only waste resource and also pollute environment.Corii Bovis seu Bubali is mainly mutually compiled by the collagen fiber of beamforming and microbeam type
Knit, be mutually wound around and form.These collagen fiber are natural fiber, have that pulling force is strong, hygroscopicity strong,
Soft, free from extraneous odour, the features such as antistatic, anti-anti-flammability are strong, if extracted by certain mode,
Follow-up fabric of can making, or make base fabric, or other purposes by nonwoven fabric technology so that cattle
Skin waste material has obtained good utilization, not only avoids waste, has saved cost, and takes full advantage of
Waste material, decreases the waste material pollution for environment, has now more pay attention to for sustainable development
Important meaning.
Summary of the invention
It is an object of the invention to provide the manufacture method of kind of a kind of Modified Kraft friction material fiber, described in change
Property Corii Bovis seu Bubali friction material fiber there is high speed characteristics, can improve the polishing machine of friction material, increase friction
The coefficient of friction of material, reduces the impact that friction material is shunk and expands by high temperature；There is higher pore
Rate, it is possible to reduce brake noise；Quality is soft, has higher toughness can play the effect that lubrication is stable,
Improve the impact flexibility of friction material；And pollution-free, resistant to elevated temperatures advantage, and prepare with low cost.
The technical scheme is that for achieving the above object
The manufacture method of a kind of Modified Kraft friction material fiber, comprises the steps:
Step one, clean: Corii Bovis seu Bubali split is carried out, cleaning scaling on pigment, greasy dirt and
Impurity；
Step 2, disinfect:
1) the sodium arsenite solution of configuration 0.5%, is immersed Corii Bovis seu Bubali 1～2 minute and i.e. takes out,
Then Corii Bovis seu Bubali is soaked 1～2 day in clear water；
2) Corii Bovis seu Bubali in clear water is pulled out, put into the cement pit liming 3 hours being contained with liming liquid, institute
State liming liquor manufacture method as follows: 25 parts of Calx, 5 parts of sodium sulfide, stir in starchiness with water；
Step 3, tanning:
1) Corii Bovis seu Bubali after liming is put into clear water soak 12 hours；
2) Corii Bovis seu Bubali after soaking, puts in the saturated Natrii Sulfas solution of 35 DEG C-45 DEG C, and tanning 0.2 is little
Taking out time after and dry, place in saturated Natrii Sulfas solution and soak after half an hour, tanning took after 0.2 hour
Going out to dry, be placed again in saturated Natrii Sulfas solution soaking after half an hour, tanning is taken out after 0.2 hour and is dried in the air
Dry, then remove the floating nitre on skin；
3) tanned Corii Bovis seu Bubali is put in the edible vegetable oil of 35 DEG C-45 DEG C, after permeability is saturated, naturally dry in the shade
Do to half storey；
Step 4, drying: the Corii Bovis seu Bubali naturally dried in the shade to half storey is dry is dried, dry temperature and be 60-80 DEG C；
Step 5, pulverizing: the Corii Bovis seu Bubali Special grinder for disintegrating after drying is pulverized.
Further technical scheme, the drying temperature of described step 4 is 70 DEG C.
The Modified Kraft friction material fiber that the present invention prepares has the advantage that
1, there is high speed characteristics, braking ability and the polishing machine of brake block after adding brake block, can be improved.
Brake block friction material is received by the high temperature produced when can reduce brake block brake after 2, adding brake block
Contracting and the impact expanded, and have the higher porosity, it is possible to reduce brake noise.
3, quality is soft, has higher toughness, and produce when advantageously reducing brake after adding brake block trembles
Dynamic, play the effect that lubrication is stable, improve the impact flexibility of brake block.
4, non-environmental-pollution, it is possible to the environmental protection fiber of degraded automatically, intensity is good, and fiber dendroid is tied
Structure, it is possible to improve the performance of compound, is the excellent succedaneum of asbestos fibre.
5, resistance to elevated temperatures, frictional behaviour are better than cellulose fibre, have certain elasticity, to improving friction
The pliability of material mixing material, compressibility, sealing have preferably effect.Stablize coefficient of friction, reduce
Wear hardness is better than cellulose fibre.
