Flameproof treatment apparatus for carbon material precursor and flameproof treatment method for carbon material precursor using same

摘要

To provide a flame resistance treatment device of a carbon material precursor capable of controlling a flame resistance treatment temperature of the carbon material precursor, providing a flame resistant article excellent in heat resistance (carbon material precursor with the flame resistance treatment conducted), and manufacturing a carbon material at high yield.SOLUTION: There is provided a flame resistance treatment device of a carbon material precursor having a heating device for conducting a flame resistance treatment on the carbon material precursor, infrared absorption intensity measurement means for measuring infrared absorption intensity of the carbon material precursor before the flame resistance treatment and after the flame resistance treatment and temperature control means for feedback controlling a temperature in the heating device with a ratio of infrared absorption intensity caused by an in-plane vibration of a six-membered ring structure in the carbon material precursor after the flame resistance treatment to infrared absorption intensity caused by the in-plane vibration of the six-membered ring structure in the carbon material precursor before the flame resistance treatment as an index so that production of the six-membered ring structure is promoted in the flame resistance treatment of the carbon material precursor.SELECTED DRAWING: Figure 1
