To enhance the strength and antimicrobial properties of paper cultural relics, and prolong the life of paper cultural relics, it is an urgent need to prepare new material for preservation and protection of paper. In this paper, CMC-beta-CD-SG was synthesized with beta-CD as carrier and sulfaguanidine as inclusion complex, the suitable conditions for the synthesis of CMC-beta-CD-sulfaguanidine was obtained. By testing the effects of different mass concentrations of sulfaguanidine solution on the tensile strength, tearing degree, folding times, whiteness, gloss and antimicrobial properties of the paper, the suitable conditions for coating paper were found. The results show that when inclusion mass concentration of 3 mg/mL is coated on the paper, its mechanical properties are improved, the gloss is slightly increased, and the whiteness is basically unchanged. At the same time, the paper has certain antimicrobial properties, which is in line with the principle of "repairing the old as old". CMC-beta similar to CD-SG studied in this paper exhibits properties of reinforcing, slow-releasing and antimicrobial activity for paper protection, which is an innovation of paper protection material, provides the theoretical basis and data reference, as well as a new research idea and technical approach for the development of products for paper protection.
