Preparation of CMC-β-CD-sulfaguanidine and its application for protection of paper

Abstract CMC-β-CD-sulfaguanidine was synthesized by saturated aqueous solution method with β-CD as carrier and sulfaguanidine as inclusion compounds based on the preparation of CMC-β-CD, through single factor and orthogonal experiment, suitable conditions for the synthesis of CMC-β-CD-sulfaguanidine was obtained. The structure of the synthesized CMC-β-CD-sulfaguanidine was characterized by infrared spectroscopy, UV spectroscopy and SEM. The inclusion compounds was applied to paper reinforcement. By testing the effects of different mass concentrations of sulfaguanidine solution on the tensile strength, tearing strength, folding times, whiteness, glossiness and antibacterial properties of the paper, the suitable conditions for coating paper were found. The results show that when inclusion concentration of 3 mg/mL is coated on the paper, its mechanical properties are improved, the glossiness is slightly increased, and the whiteness is basically unchanged, at the same time, the paper has certain antibacterial properties. CMC-β-CD-SG studied in this paper has the functions of strengthening, slow-releasing, anti-mildew and antibacterial for paper, 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.
