Embodiment 1
[0033] The present embodiment provides a preparation method of a tough aldehyde-free soybean meal-based wood adhesive, and the adhesive is prepared according to the following weight ratios:
[0034] Modified soybean meal based wood 30 kg
[0035] Branched long chain starch 3 kg
[0036] Polyacrylamide 0.1kg
[0037] Homemade multifunctional epoxy compound 2kg
[0038] Sodium hydroxide solution 0.3kg
[0039] The present embodiment also provides the preparation method of the above-mentioned adhesive, and the specific preparation steps are as follows:
[0040] (1) Weigh the components according to the weight ratio, add the branched long-chain starch into the dispersion medium water, sonicate for 15 minutes, then add half the weight of modified soybean meal-based wood, use a high-pressure homogenizer, under a pressure of 30MPa and 0.5 Under the action of the emulsifying force of MPa, the homogeneous emulsification was carried out for 20 minutes;
[0041] (2) Add the remainin...
