NOVELTY - Packaging paper adhesive material comprises 20-40 pts. wt. soybean protein isolate, 2-6 pts. wt. sodium alginate, 2-4 pts. wt. carboxymethyl cellulose, 50-100 pts. wt. silica sol, 0.5-1 pts. wt. glycerin monostearate, 0.5-1.2 pts. wt. tripolyglycerol monostearate, 2-4 pts. wt. acetic anhydride, 4-10 pts. wt. guar gum, 5-10 pts. wt. nanometer graphene oxide, 5-10 pts. wt. nano talc powder, 20-30 pts. wt. ethanol and 200- 300 pts. wt. water. USE - The method is useful for packaging paper adhesive material. ADVANTAGE - The material has both inorganic and organic properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing adhesive material, comprising (i) adding glycerin monostearate, tripolyglycerol monostearate to water, and ultrasonically dispersing to obtain aqueous solution, (ii) heating the solution in water bath, adding acetic anhydride, soybean protein isolate, stirring, uniformly mixing to obtain hydrophobically modified soybean protein solution, (iii) adding sodium alginate, carboxymethylcellulose and guar gum to the soy protein solution, mixing and stirring to obtain mixed solution, (iv) adding nano graphene oxide and nano talc powder to ethanol, and ultrasonically dispersing to obtain ethanol solution, and (v) adding the ethanol solution to the mixed solution prepared in step (iii) while stirring, adding silica sol, ultrasonically dispersing and adjusting pH to 65-7.5 before discharging.
