Abstract
The heat resistance and mechanical properties of the alcohol-liquefied wood-based epoxy resins were studied in relation to the wood-liquefi ed solvent type. The wood-liquefi ed solvents were polyethylene glycol (PEG) as the aliphatic alcohol and bisphenol-A ethylene oxide adduct (BPAEO) as the aromatic alcohol. BPAEO was better than PEG as the woodliquefi ed solvent. The heat resistance and the tensile properties of the BPAEO-liquefi ed wood-based epoxy resin were higher than that of the PEG-liquefi ed one. The aromatic structure of the wood-liquefi ed solvent resulted in the high heat resistance and tensile properties of the wood-based epoxy resins. The glass transition temperatures and flexural properties were improved with increasing the biomass content in the BPAEO-liquefi ed wood-based epoxy resins.
