| Abstract: | In this paper,a kind of calcium lignosulfonate was phenolated by the method of phenol-sulfuric acid.The water-undissolved part of the phenolated lignosulfonate was epoxidized by epichlorohydrin catalyzed by sodium hydroxide.Two kinds of lignin base epoxy resins were prepared in this way.Structures of the lignin base epoxy resins and their forming mechanisms were analyzed according to results of characterization by IR, 1H-NMR, 13 C-NMR,and so on. |
