According to the performance requirements of sand-fixing on the surface of toner paper, butyl acrylate (BA) and isooctyl methacrylate (EHMA) are soft monomers, and methyl acrylate (MA) and methyl methacrylate (MMA) are hard The monomer, hydroxypropyl acrylate (HPA) is a crosslinking monomer, and methacrylic acid (MAA) and glycidyl methacrylate (GMA) are functional monomers. A semi-continuous seed emulsion polymerization method was used to prepare an aqueous acrylic resin emulsion (WSAE-G) with a core-shell structure. Use it as a binder and film-forming agent for sand-fixing on the surface of toner paper. The effect of the amount of GMA on the particle size, stability and viscosity of the emulsion was discussed. The polymer structure was analyzed using Fourier infrared spectroscopy (FT-IR) and thermal weight loss analyzer (TSC). The size and morphology of emulsion latex particles were characterized by dynamic light scattering (DLS) and transmission electron microscopy (TEM). A universal material testing machine is used to test the mechanical properties of the film. Scanning electron microscopy (SEM) test was performed on the surface of sand-fixed products. The results show that when the amount of GMA is 1 wt%, the emulsion particle size is 142.4 nm, the PDI is 0.063, the emulsion dispersion stability index TSI is 0.162287, and the TEM shows a clear core-shell structure. At the same time, the tensile strength of the GMA film without addition increases from 5.518MPa to 9.057MPa. After being applied as a sand-fixing agent on the surface of toner paper, the binding force between the layers of the toner paper is 244.9 J/m2, the emulsion bonding strength is large, and it is not easy to fall off the sand. The SEM image shows that the formed sand-fixing layer is more uniform and has better matteness.
