▎ 摘　　要

NOVELTY - Graphene sizing agent composition comprises 0.1-1.5 wt.% graphene or graphene derivatives, 5-10 wt.% cationic surfactant, 2-8.5 wt.% dispersant, 10-15 wt.% paraffin, 30-70 wt.% modified starch, 5-10 wt.% chitosan and 5-25 wt.% deionized water. USE - The composition is useful in toilet paper, antibacterial medical paper, antibacterial culture paper production and processing. ADVANTAGE - The composition improves paper's antibacterial, anti-mite and mildew performance; and also improves strength of the paper. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene sizing agent composition comprising dissolving modified starch in deionized water to obtain modified starch solution, adding cationic surfactant, paraffin and chitosan into modified starch solution, and dispersing to obtain composition A, mixing composition A with graphene or graphene derivative and dispersant, dispersing, emulsifying, controlling the pH value of 4-5 to obtain sizing composition.
