摘要
Enzymatic hydrolysis lignin (EHL) was utilized to partially replace phenol for preparing phenolformaldehyde (PF) resin. The influence of lignin substitution rate on the properties of the lignin-modified phenol-formaldehyde (LPF) resin was investigated. Lignin substitution of 60 wt% did not deteriorate the adhesive strength of PF resin. FTIR analysis of the resins revealed that the incorporation of EHL made no big difference in chemical structure, but led to a deteriorated thermal resistance. The comparison between LPF and bio-ethanol production residue-modified phenol-formaldehyde (RPF) resins elucidated that the purification process was beneficial for its higher substitution application and better performance of adhesive.
