| Abstract | The water-based copolymer emulsion of MMA (Methyl methacrylate), BA (Butyl acrylate), and MA (Methacrylic acid) was prepared by soap-free emulsion polymerization. Inorganic silica nanoparticles were added to stabilize the latex particles in place of surfactants to improve the mechanical properties of the copolymer film. The effects of silica content, monomer ratio of MMA to BA, and functional monomer MA were studied. The addition of silica nanoparticles improved the stability and the dispersion of the emulsions. Solid content, viscosity, hydrophilicity, hardness adhesion, chemical resistance and tensile strength were all enhanced by silica nanoparticles. Water soluble monomers, like MMA and MA, increased the hardness, hydrophilic property and tensile strength of the copolymer film. The particle size and alkali resistance were improved by MMA, but reduced by MA. Additionally, MA improved the solid content and water resistance of the film, but reduced the adhesion and acid resistance of the copolymer film. |
