▎ 摘　　要

NOVELTY - Vegetable and fruit antibacterial fresh-keeping wrapper comprises 55 to 75 pts. wt. pulp fibers, 8 to 15 pts. wt. adjuvant, and 3 to 8 pts. wt. antibacterial agent. The antibacterial agent is a mixture of Dandelion extract, wormwood extract and graphene oxide/fluoroacrylate modified cellulose. USE - Vegetable and fruit antibacterial fresh-keeping wrapper. ADVANTAGE - The vegetable and fruit antibacterial fresh-keeping wrapper has good effect of plant sterilizing inhibiting other graphene/modified cellulose, has hydrophobic and oleophobic properties, inhibits the growth of bacteria and prevents colon Bacillus, Staphylococcus aureus and has good antibacterial effect, is simple to prepare. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene oxide/fluorinated acrylate-modified cellulose, which involves: (A) pre-emulsifying fluorine-containing acrylate-modified cellulose, emulsifier, water and fluorine-containing acrylate monomer; (B) adding cellulose solution and the initiator under inert gas to synthesize the modified cellulose, where polymerization temperature is 50-60 degrees C, and the polymerization time is 4-7 hours, the emulsifier is sodium lauryl sulfate, the amount of emulsifier is 3 to 5 wt.% fluorine-containing acrylate monomer, initiator is potassium persulfate, and the amount of the initiator is 2-6% of fluorine-containing acrylate monomer, mass ratio of cellulose to fluorine-containing acrylate monomer is 1:2-1:6; (C) preparing graphene oxide/fluorine-containing acrylate modified cellulose by mixing strong alkali, urea and thiourea solution, cooling to (-10)-(-20) degrees C, stirring, adding the modified cellulose and uniformly dispersing graphene oxide solution, stirring for 4-6 hours, adjusting the pH to neutral to get Graphene oxide/modified cellulose antibacterial oil repellent additives, where mass ratio of modified cellulose with graphene oxide is 1:0.2 to 0.5; and (D) reacting with strong base modified cellulose, urea, thiourea in mass ratio of 1:1.6:1.3:1.6.
