Abstract

•Proper duration of acid hydrolysis improved grafting parameter of the starch-based wood adhesive.•Proper acid hydrolysis of the starch inhibited the retrogradation of starch molecules in the starch-based wood adhesive.•Two hours was the best acid hydrolysis time to enhance the stability and performance of the starch-based wood adhesive.•The acid hydrolysis of the starch first affected the adhesive system positively and then negatively with the acid hydrolysis duration from 0 h to 3 h..

In this study, the effect of different durations of acid hydrolysis on the improvement of the properties of starch-based wood adhesive was investigated through a variety of determination methods The improved properties were analyzed using the pasting properties, viscosity, shear performance in dry and wet states, fourier infrared spectrometer, dynamic time sweep, and low filed nuclear magnetic resonance spectroscopy. Starch hydrolysis improved the viscosity stability, bonding performance, and water resistance of the starch-based wood adhesive.
