Description
Technical field
The invention belongs to a kind of for pitch based carbon fiber precursor fiber spinning used additives technical field, be specifically related to a kind of asphalt-based carbon fiber spinning finish.
Background technology
Finish is the important auxiliary agent of production high-performance precursor and Carbon fibe, the manufacture (particularly the manufacture of High Property Carbon Fibers) of Carbon fibe has strict requirement to spinning oil: as excellent resistance to elevated temperatures, to guarantee to play can prevent again the effect of precursor adhesion by boundling at High Temperature Pre oxidation and charing initial stage; Excellent antistatic property, to give the good convergence of precursor and processability, ensures carrying out smoothly of spinning and preoxidation process; Excellent lubricity and antiseized isolation, make fiber be easy to fibrillation to play the good monofilament adhesion that prevents at spinning, pre-oxidation and charing initial stage, greatly reduce or eliminate burr, doubling and fracture of wire; The wettability excellent to Carbon fibe, to make to oil evenly, guarantees the homogeneity of precursor, oxidization fiber and carbon filament quality.
Pitch based carbon fiber can be used as the fortifying fibre of advanced composite material, is indispensable new and high technology material in space flight and aviation and national defense industry.Pitch based carbon fiber production process is by pitch fibers after finish oils, and drying makes asphalt carbon fiber precursor, non-fusible in the air of 250-350 DEG C afterwards, makes non-fusible silk, the temperature charing then in 1000 DEG C of inert gases, obtained Carbon fibe.
The domestic finish being exclusively used in the spinning of pitch based carbon fiber precursor is few at present, the finish produced for PAN based carbon fiber is relatively many, but be organosilicon finish substantially, organosilicon finish itself has excellent performance, but act on asphalt carbon fiber and have following shortcoming: because organosilyl convergence is good, connect tight between tow but 98 machine silicon can be had effectively to separate, but such finish is in the infusible process of pitch fibers, cross-linking reaction can be there is and high viscosity in organosilicon finish because of heating, the comparatively strong oil film of one deck is formed on pitch fusion-free fibre surface, due to the fragility of pitch fusion-free fibre itself, crosslinked organosilicon membrane can make fibre bundle harden, and easily brittle failure.The difficulty that this firmly crisp fibre bundle makes follow-up production become.More burr can be produced and affect the quality of final products in the process of winding.
Application publication number be CN103757899A application discloses a kind of universal pitch-based carbon fiber spinning oil, although this finish can solve in universal pitch charcoal fibre preparation process exist easy adhesion, electrostatic and friction problem, but be only applicable to little synnema scope, when synnema reaches 1K, when curing process step, there will be molten also phenomenon.
Summary of the invention
The object of the invention is to solve the technical problem that there will be molten also phenomenon when existing asphalt base carbon fiber spinning finish exists for spinning large bundle pitch based carbon fiber silk, a kind of asphalt-based carbon fiber spinning finish is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of asphalt-based carbon fiber spinning finish, it is made up through ultrasonic mixing 0.5h ~ 3h according to following mass percent of following raw material: carbon element powder 5%-45%, silicone oil 3%-6%, antistatic additive 0.1%-3%, obvolvent agent 0-0.3%, wetting agent 0.02%-2% and point fine agent 0-0.2%, all the other are deionized water.
Described carbon element powder be in graphite powder, modified graphite powder, carbon black or Graphene any one or a few with arbitrarily than mixture, its particle size is 0.001 μm-2 μm.
Described silicone oil be in amino-modified silicone oil, epoxy modified polysiloxane, polyether modified silicon oil, hydroxy silicon oil, methyl-silicone oil, dimethicone, ethyl silicon oil or cyanoethyl methyl polysiloxane one or more with arbitrarily than mixture.
The preparation method of described modified graphite powder is: first graphite powder and red fuming nitric acid (RFNA) are mixed with the mass ratio of 1:2-4, then 70-100 DEG C is warming up to, stir 0.5-4h continuously again, finally with distilled water graphite water powder until pH value is 5-7, obtain the modified graphite powder that oxygen content is 0.1%-0.5%
The modification ammonia mass fraction of described amino-modified silicone oil is calculated as 0.001-0.05% to hold envelope ammonia-NH2; The modification amount of described epoxy modified polysiloxane is calculated as 0.001-0.05% with epoxy radicals-CHCH2O; The modified polyether mass fraction of described polyether modified silicon oil is between 0.2-0.7%, and the degree of polymerization of the construction unit of polyethers is between 5-25.
The invention has the beneficial effects as follows: the present invention is used in the spinning production process of pitch based carbon fiber precursor fiber, can at monofilament surface homogeneous film formation, the friction and wear of fiber surface and roller in process of production can be prevented, thus effectively avoid fiber surface to produce defect, due to the electric action of carbon element powder, finish has good antistatic behaviour, and pitch fibers has enough flexibilities after about 300 DEG C non-fusible, can not brittle failure in receipts silk process.Therefore, compared with background technology, the present invention has the advantage when being used for there will not be molten also phenomenon when spinning large bundle pitch based carbon fiber silk, preventing the friction and wear of fiber surface and roller in production process, good antistatic behaviour and good increasing tougheness.
