Study on Surface Sizing of Cationic Polyacrylate Emulsion to Improve Mechanical Properties of Paper

Abstract:

Cationic polyacrylate emulsion was used as surface sizing agent and the effects of emulsion properties on paper mechanical properties were studied. The mechanical properties of sized paper gradually increased with the increase of solid content, viscosity and positive charge density of emulsion and decreased with the increase of particle size of emulsion. Tensile strength, folding endurance and tearing strength on machine direction were increased 33.62%, 11.99%, 6.79% respectively when the paper with single emulsion layer was used oven drying methods.
