Embodiment Construction
[0020] A method for producing a superhydrophobic composite corrugated box based on nano-titanium dioxide, comprising the following specific steps:
[0021] (1) Disperse an appropriate amount of dry kraft pulp in a chitosan solution with a concentration of 1g / L according to the ratio of 5 grams of dry kraft pulp in 1 liter of chitosan solution, and stir magnetically at a low speed to form a fiber suspension , after stirring for 20 minutes, suction filtration was carried out with a Buchner funnel, and the obtained fiber was rinsed twice with ultrapure water;
[0022] (2) Disperse the treated fibers obtained in step (1) into the modified nano-titanium dioxide solution with a concentration of 2g / L in the same ratio as in step (1), stir magnetically at a low speed to form a fiber suspension, and continue stirring for 20 minutes Finally, the above-mentioned fiber suspension was separated with a Buchner funnel, and the separated fibers were rinsed twice with ultrapure water to obtain...
