Summary: | The invention discloses a preparation method of a high-performance food oil-proof paper-based material containing a nano-fibril cellulose composite coating. The preparation method comprises the following steps: (1) preparing a nano-fibril cellulose suspension by a Tempo oxidation homogenization method; (2) adding propylene glycol alginate into water, and uniformly mixing to obtain a propylene glycol alginate solution with the mass-volume percentage concentration of 1-2%; (3) mixing the nano cellulose suspension with the mass-volume percentage concentration of 1-3% and the propylene glycol alginate solution with the mass-volume percentage concentration of 1-2% according to the mass ratio of the nano fibril cellulose to the propylene glycol alginate of 1: (1-3), uniformly stirring, dispersing for 10-20 minutes under ultrasonic waves, and removing bubbles to obtain a coating with good dispersity; (4) uniformly coating the surface of food packaging body paper with the coating liquid; and (5) fully drying the coat |
