| titleOfInvention | A kind of manufacture method of polyacrylonitrile base carbon fiber precursors |
| abstract | A manufacture method for polyacrylonitrile base carbon fiber precursors, the Third monomer of spinning material polyacrylonitrile resin is furoate clothing, comprises successively: resin DMSO or DMAc is mixed with spinning solution, obtains as-spun fibre through spray silk and solidification forming; As-spun fibre carries out water-bath drawing-off and uses deionized water drip washing in the aqueous solution of spin solvent; As-spun fibre is first placed in acidic aqueous solution and floods dipping 1 ~ 5min in 2 ~ 10min, NaOH or potassium hydroxide aqueous solution; As-spun fibre carries out by rinsed with deionized water after water-bath drawing-off in pure water, to rinsing liquid in neutral and continue rinsing 5 ~ 15min again after not measuring sodium ion or potassium ion; Through to oil and the last handling process such as compacting by drying makes polyacrylonitrile base carbon fiber precursors product.The technical problem that the present invention solves is that precursor passes through to wash the object reaching purifying, and fibrous fracture intensity is unaffected simultaneously, thus makes up the defect of prior art existence. |
