The invention discloses a preparation method of a soy protein adhesive. The preparation method is characterized in that physical-chemical modification, cross-linking, grafting and other steps are carried out for preparing the soy protein adhesive by using soy protein as a raw material. The preparation method has the advantages that the raw materials used are nontoxic, the processing technology is simple, the process is environmentally-friendly and does not release toxic and harmful substances, the environment can be protected, and the soy protein adhesive is able to be degraded. The soy protein adhesive is applicable to food-grade paper package, wood processing, common boxes, barrels, bags, corrugated paper boxes and other paper packaging products, as well as applying to the fields of pasting wallpaper, postage stamp, label, seal and the like. |
