| Plant protein-based adhesives from oilseeds have the advantages of extensive sources, non-toxic, renewable and simple preparation. However, the development and application of this kind of adhesives are limited by the problems of low bonding strength, poor water resistance and easy mildew. The research and application progresses of several plant protein-based adhesives from oilseeds in the wood industry in recent years were reviewed, such as soy protein adhesive, peanut protein adhesive and cottonseed protein adhesive. The modification methods to improve the water resistance of protein adhesive were summarized, including physical modification, denaturant modification, grafting modification, crosslinking modification, biomimetic modification, enzyme modification, nanomaterial modification, composite modification and so on, and the problems of plant protein-based adhesives were pointed out. The future development direction and application prospects were put forward. |
