| titleOfInvention | The preparation method of polyacrylonitrile-based carbon fibre |
| abstract | A preparation method for polyacrylonitrile-based carbon fibre, the Third monomer of its precursor spinning material polyacrylonitrile resin is furoate clothing, and the resin NaSCN aqueous solution is that solvent is mixed with spinning solution, obtains as-spun fibre through spray silk and solidification forming.As-spun fibre passes through subsequently successively: in the NaSCN aqueous solution, carry out water-bath drawing-off; Use deionized water drip washing; The cushioning liquid be placed in containing sour A and salt B floods, and A is sulfuric acid, hydrochloric acid or nitric acid, and B is sodium salt or the sylvite of A; Water-bath drawing-off is carried out in pure water; Be placed in acidic aqueous solution to flood; Hot bath rinsing is carried out to rinsing liquid in neutral with deionized water.As-spun fibre is again through to oil and the last handling process such as compacting by drying obtains carbon fibre precursor.Precursor carries out pre-oxidation having in oxygen atmosphere under the state imposing drawing-off, then carries out carbonization in an oxygen-free atmosphere under the state imposing drawing-off, obtains polyacrylonitrile-based carbon fibre finished product. |
