Abstract

Industrial alkali lignin (LG) was used as raw material and ionic liquid 1-butyl-3-methylimidazolium chloride ([BMIm]Cl) was used as reaction system. Alkali lignin was dissolved into the [BMIm]Cl and modified as propyl ether lignin(HLG). Then the HLG modified lignin was used to synthesizing the lignin-based epoxy resin (LGEP) with epoxy chloropropane. The structure of LG, HLG and LGEP were characterized with FT-IR, the results indicated that the propyl groups were introduced to the LG and the reaction activity was improved. The expoxy value analysis results showed that the optimum synthesis temperature was 80°C and the epoxy value was 0.218. And the using of [BMIm]Cl improved the resin mechanical properties.
