Abstract

A high-performance wood adhesive was successfully developed by incorporating soybean oligopeptides into Camellia oleifera protein through a combination of degradation and epoxy resin crosslinking techniques. The results showed that the presence of oligopeptides boosted the creation of more active functional groups in the degradation liquid system. This process enhanced the adhesive’s initial viscosity and overall stability. As a result, the adhesive’s performance was significantly improved, making the bond more robust and long-lasting. However, a notable drawback was observed: the storage duration of the adhesive was shortened from 10 h to 3.5 h. Despite this limitation, the adhesive exhibited several advantageous properties, including a high curing reaction rate, a relatively low curing temperature, and excellent thermal stability. Additionally, the prepared adhesive demonstrated superior bonding strength and outstanding water resistance, making it a promising alternative for various wood-based applications.
