The invention discloses a preparation method of a protein-base adhesive, belonging to the field of adhesives. The preparation method comprises the following steps: carrying out enzymolysis on high proteins in high gluten flour, centrifuging to obtain a precipitate, adding garlic, ginger, chitosan and the like into the precipitate, and fermenting so that the mixture has the anticorrosive effect; centrifuging to obtain a supernate, regulating the pH value, adding a surfactant, oscillating, carrying out crosslinking reaction with glutaric acid, adding konjaku flour to increase the viscosity, mixing the viscous substance and fermentation product, and carrying out acylation modification with acetic anhydride, thereby obtaining the adhesive. By combining bioenzyme modification and chemical modification, the method draws on each other's strength, and thus, has better effects. The chemical modification endows the proteins with new functional groups and lowers the hydrophilicity; and the bioenzyme modification is util
