Beschreibung
Zusammenfassung:	The invention discloses a preparation method of high-strength corrugated paper, and relates to the technical field of papermaking, and the preparation method is technically characterized by comprising the following steps: S1, raw material preparation: mixing waste paper pulp and wood fiber pulp in proportion; s2, biological enzyme preparation: preparing two kinds of biological enzymes, namely cellulase and chitosanase; s3, biological enzyme treatment: adding cellulase and chitosanase into the mixed slurry in proportion, and carrying out enzymolysis treatment; the pulp subjected to enzymolysis treatment is subjected to papermaking, and the high-strength corrugated paper is obtained.The high-strength corrugated paper has the technical effects that through the treatment process of adding cellulase, the fiber flexibility and binding force of the corrugated paper are remarkably enhanced, and then the tensile strength of the corrugated paper is greatly improved; the prepared cellulose has excellent toughness and pl
