Preparation method of molded pulp meal box containing quaternary ammonium silanized nanocellulose

The invention discloses a preparation method of a molded pulp meal box containing quaternary ammonium silanized nanocellulose, which comprises the following specific preparation steps: step 1, mixing a quaternary ammonium silane modifier with the concentration of 1-50wt% with nanocellulose gel, and carrying out quaternary ammonium silanized modification reaction at the temperature of 10-100 DEG C to obtain quaternary ammonium silanized nanocellulose gel; step 2, mixing the quaternary ammonium silanized nano-cellulose gel into a paper pulp solution according to a mass ratio of 1: (10-100) to obtain antibacterial mixed pulp; step 3, feeding the antibacterial mixed slurry into a mold forming machine for forming and processing; and demolding the formed wet paper blank, and drying in a drying oven to obtain the molded pulp meal box containing quaternary ammonium silanized nano-cellulose. The meal box prepared by the method disclosed by the invention has super-strong antibacterial property and super-hydrophobic pro
