| titleOfInvention | The preparation method of a kind of polyacrylonitrile base carbon fiber precursors |
| abstract | The present invention relates to the preparation method of a kind of polyacrylonitrile base carbon fiber precursors, after polyacrylonitrile spinning solution wire vent, adopt and be introduced into one section of non-condensable bath, then the combination coagulation forming technique entered in precipitation bath. Comprise the steps: that vinyl cyanide spinning solution is after combination coagulation forming technique coagulation forming specifically, successively through drawing-off, wash, oil, dry, steam drafting or boiling water drawing-off, heat setting type, baking step, finally receive silk. The present invention can overcome the shortcoming of conventional dry wet method and wet processing, is conducive to control precursor cortex construction. What adopt that this technique can realize being greater than 300m/min spins speed, and the precursor obtained has the surface groove structures of similar wet method precursor, and feel is soft, and fibrillation is good, and after carbonization, intensity is higher than 5.8GPa. Belong to preparation method's technical field of polyacrylonitrile base carbon fiber precursors. |
