摘      要:More than a century after its initial synthesis,urea-formaldehyde(UF)resins still have dominant applications as adhesives,paints,and ***,formaldehyde in this industry produces formaldehyde emissions that are dangerous to *** have spent the last decade replacing formaldehyde and phenol with environmentally friendly substances such as glyoxal and tannin to create bio-based *** review covers recent advances in synthesizing glyoxal tannin-based resins,especially those made from sustainable raw material substitutes and changes made to synthetic processes to improve mechanical *** efficacy of using tannin-glyoxal adhesives in producing wood-based composites has been *** glyoxylate reaction forms cross-linked bridges between the aromatic sites of the tannin and glyoxal molecular *** tannin adhesive with a greater percentage of glyoxal than tannin will produce an adhesive with better *** gel time reduces as the hardener concentration rises from 7.5%to 15%when glyoxal is used in ***,excessive amounts of glyoxal will result in a decrease in viscosity *** exhibits faster delivery degradation when it reaches a maximum temperature of approximately 130°C,although it initiates the curing process slightly slower at 110°*** glyoxal to tannin-based adhesives can improve the mechanical properties of composite *** wet shear strength of the resulting plywood is increased by 105.4%with the addition of 5-weight percent tannin-based resin with glyoxal as a cross-linker in Soy Protein *** glyoxal as a hardener,the panels produced showed good internal bond strengths(0.35 MPa)and met the international standard specifications for interior-grade panels.
