摘要：

Thermal gravimetric analysis (TGA) and X-ray diffraction (XRD) were used to analyze the pyrolysis of pitch, furan, phenolic aldehyde and epoxy binders. Their micro-structures after carbonization were also studied. The relationship between alkali metal penetration resistance of binders, their pyrolysis activation energy (Ea) and micro-structure after carbonization was investigated. The results show that for binders containing turbo stratic graphite or a transitional structure between turbostratic graphite and graphite, the higher the degree of graphitization the better the penetration resistance of the binder. When the binder micro-structure is in a transitional stage from amorphous or other non-graphitic structures to turbostratic graphite, the penetration resistance of the binders deteriorates. For these microstructures, the higher the Ea, the better the penetration resistance. The ÅË of pitch, furan, phenolic aldehyde and epoxy are 47.20 kJ/mol, 93.11 kJ/mol, 178.11 kJ/mol and 780.32 kJ/mol respectively.
