Hydrophobic enhanced calligraphy and painting paper and making method thereof

The invention discloses hydrophobic enhanced calligraphy and painting paper and a making method thereof and belongs to the technical field of paper making. The hydrophobic enhanced calligraphy and painting paper disclosed by the invention comprises calligraphy and painting paper and a hydrophobic modification nano cellulose coating, wherein the hydrophobic modification nano cellulose coating is formed on the surface of the calligraphy and painting paper; hydrophobic modification nano cellulose is nano cellulose prepared by firstly performing oxidation pretreatment on cellulose by using a 2,2,6,6-tetramethyl piperidine oxide to obtain cellulose with carboxyl, and by further performing high-pressure homogenization; and the nano cellulose is further subjected to hydrophobic modification by using a two-step method, namely, in a first step, glutaric anhydride and propionic anhydride are adopted as composite anhydride as a reagent for esterification modification on the nano cellulose, and ina second step, 1-tridecy
