Embodiment 1

[0038] This embodiment provides an adhesive for wood-based panels, and the adhesive is prepared according to the following weight ratio:

[0039] Demineralized water 70 Kg

[0040] Defatted Soy Protein Powder 30 Kg

[0041] Denaturant 1 Kg

[0042] Enhancer 10kg

[0043] Among them, the protein content of defatted soybean protein powder is more than 43% (purchased from Huifu Grain and Oil Co., Ltd.); the denaturant is commercially available ordinary magnesium hydroxide (purchased from Tianjin Chemical Research Institute, with a content of 98%); the enhancer is homemade reduced wood Vegetables (solid content 60%, viscosity 6400mPa.s).

[0044] This embodiment provides the preparation method of above-mentioned adhesive simultaneously, and specific preparation steps are as follows:

[0045] 1) In a mixer equipped with a stirrer, add all the demineralized water, defatted soy protein powder, and mix well.

[0046] 2) Add denaturant and stir evenly.

[0047] 3) Add enhancer an...
