| titleOfInvention | Method for oiling small-filament-bundle PAN-based carbon fiber precursor |
| abstract | The invention relates to a method for oiling a small-filament-bundle PAN-based carbon fiber precursor, and the method is mainly used for solving the problem that an oiling agent has poor heat resistance during the use process caused by that the adopted oiling agent for the carbon fiber precursor in the prior art is large in emulsifying agent dosage. The technical scheme adopted by the invention is as follows: under the conditions of temperature of 30-50 DEG C and normal pressure, soaking compacted PAN-based carbon fiber precursor with a filament bundle of less than 24K by utilizing a 0.5-3.0wt% oiling agent, wherein the used oiling agent comprises the following components in parts by weight: a) 40-60 parts of amido modified dimethyl polysiloxane A, b) 5-20 parts of amido modified dimethyl polysiloxane B, c) 10-30 parts of polyether modified dimethyl polysiloxane and d) 5-20 parts of emulsifying agent, so that the problem in the prior art is well solved. The method can be used in the industrial production of the small-filament-bundle PAN-based carbon fiber precursor. |
