摘      要：Lignin-based epoxy resin（LEP） was prepared from acetic acid lignin（AAL）.AAL was prepared from the atmospheric acetic acid pulping of eucalyptus *** was first phenolated with phenol to obtain phenolized lignin（PL）.Then PL was epoxidised with epichlorohydrin （ECH） in alkali medium to obtained *** LEP was mixed with diglycidyl ether of bisphenol A（E-44） and the mixture was cured with triethylenetetramin（TETA） as the *** initial thermal degradation temperatures （r/s） of the epoxy blends were declined with the increasing LEP content in the *** mass residue at 500℃(MR) was raised with the increasing LEP content. The adhesive shear strength of the blends was improved with LEP in content of up to 40%,and the maximum occurred at a LEP content of 20%.
