Embodiment 1
[0053] 1) Prepare materials according to the following weight:
[0054]
[0055] 2) Add sodium carbonate and defatted soybean protein powder into demineralized water in a reaction kettle equipped with a stirrer, thermometer and condensing device, and stir evenly;
[0056] 3) Heat the obtained mixture of sodium carbonate, defatted soybean protein powder and demineralized water to 45-47°C and keep it warm for 3 hours;
[0057] 4) Cool down the mixture obtained in the previous step to 30°C to obtain a uniform soy protein mucus;
[0058] 5) Add tannin-glyoxal resin to the soy protein mucilage obtained in the previous step, and stir evenly to make a soy protein adhesive for wood-based panels.
