Developing a paper sizing agent that meets the requirements of low cost, high quality, and environmental sustainability is significant yet challenging. This study presents a novel degradable gelatin-based coating emulsion for paper surface sizing, which successfully enhances the mechanical properties and water resistance of corrugated papers.
Developing a paper sizing agent to meet the requirements of low cost, high quality of the paper, and environmental sustainability is significant but remains a challenge. Herein, a novel degradable gelatin-based coating emulsion for paper surface sizing was developed by a simple one-step polymerization and blending process. Poly(methacrylic acid) (PMAA) was first introduced to a gelatin solution to form gelatin-PMAA emulsion (G-PMAA) through the formation of hydrogen bonds between PMAA and gelatin. The addition of PMAA endowed gelatin with the increased hydrophobicity and the decreased upper critical solution temperature. Then, a relatively small amount of the flexible poly(butyl acrylate) (PBA), which imparted the toughness of the formed film, was blended with the G-PMAA emulsion to form G-PMAA/PBA emulsion. The G-PMAA/PBA emulsion with a high gelatin content of 0.2 g/mL was in the sol state at room temperature, which facilitated the application of the G-PMAA/PBA emulsion. The corrugated papers sized by G-PMAA/PBA emulsion exhibited excellent mechanical properties and water resistance.
