Nowadays, formaldehyde-based adhesives are heavily used in the production of WBP, which is the primary source of indoor formaldehyde pollution and severely affects people's health, work and living quality. In recent years, soy protein adhesives have attracted extensive attention in the field of wood adhesives because of their advantages such as non-toxic, biodegradable, low cost and convenient processing. However, compared with the widely used commercial formaldehyde-based adhesives such as phenolic resin and urea-formaldehyde resin, soy protein-based adhesives have some shortcomings in low bonding strength, poor water resistance and poor mildew resistance. In view of the above problems, it is commonly used to functionalize soy protein adhesives by physical and chemical means such as cross-linking modification, mixed modification, structure modification, hydrolase modification and filling modification. The different methods of functional modification of soy protein adhesive were reviewed, the problems of different modification methods were summarized, and the future development of soy protein adhesive was prospected.
