Abstract

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-tridecylamine and n-decylamine are reacted with the nano cellulose after esterification modification through an electrostatic adsorption function to form a complex. As the nano cellulose used in the paper is small in size and is easy to deposit on the surface of the paper or infiltrate into pores, the vapor barrier performance and t he hydrophobicity of the paper can be improved,and in addition, the strength property of the calligraphy and painting paper can be remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a hydrophobic enhanced calligraphy and painting paper and a preparation method thereof. Background technique [0002] The differentiated water absorption and ink absorption of calligraphy and painting paper have become one of the key links in the production of art paper. All the existing paper for calligraphy and painting is made of plant fiber without too much treatment, which will easily absorb moisture and become moldy when the humidity is high. In addition, the strength of calligraphy and painting paper is not high and it is easy to be damaged. These are also issues that should be paid special attention to during production. This shows that the calligraphy and painting paper in the prior art mainly has the following technical problems: [0003] 1. Enhancement of calligraphy and painting paper [0004] The fiber materials used in calligraphy and painting pap...
