On the basis of introduction of tannin with renewable and environment- friendly biomass rawmaterial,the research progress of some condensed tannin-biomass raw materials(such as Acacia mearnsii,Larixgemlini and Acacia mangium) in modified PF(phenolic resin) adhesives was summarized,and somedisadvantages(such as ultrahigh adhesive viscosity,excessive reactivity between tannin and formaldehyde,andultrashort adhesive applicable period) in tannin modified PF adhesives were presented. Finally,the researchdirection in tannin modified PF adhesive...
