METHOD OF PRODUCING CARBON FIBROUS MATERIAL Russian patent published in 2012 - IPC D01F9/16 D01F9/12 D06M15/643

Abstract RU 2459893 C1

FIELD: process engineering.

SUBSTANCE: proposed method comprises processing initial cellulose fibrous material by liquid-phase composition containing silanol groups with molecular weight varying from 900 to 2400 and viscosity varying from 520 to 1700 cPs, and 2-7%-water solution of fire retardant. Processed material is dried to 105-125°C for 60-120 min. Then, carbonisation is performed in air at 140-170°C for 25-40 min. Carbonisation is terminated at 700°C to proceed with high-temperature processing at, at least, 2200°C.

EFFECT: high physical properties and yield.
