| titleOfInvention | Method for preparing high-ortho thermosetting phenolic fiber by adopting wet spinning |
| abstract | The invention discloses a method for preparing high-ortho thermosetting phenolic fiber by wet spinning, which comprises the steps of reacting a phenolic compound with an aldehyde compound under the action of a catalyst to generate high-ortho thermoplastic phenolic resin; dissolving the obtained thermoplastic phenolic resin in absolute ethyl alcohol, reacting with aldehydes under the action of an alkaline catalyst, and neutralizing with acid to obtain high-ortho thermosetting phenolic resin; mixing with absolute ethyl alcohol, polyvinyl butyral and the like, uniformly stirring, carrying out wet spinning, and carrying out thermocuring on nascent fiber to obtain the phenolic fiber prepared by the wet spinning. The method can obtain the phenolic fiber with good mechanical property and high limiting oxygen index without solution curing, reduces the manufacturing steps, reduces the pollution and saves the energy. |
