Study on Synthesis of In Situ Composite of Nano-SiO₂ and Vinyl Acetate-Acrylate Emulsion

Abstract:

Commercially available nanosilica was modified with silane coupling agent A-151, and then emulsion was synthesized with modified SiO₂, vinyl acetate, methyl methacrylate and butyl acrylate by polymerization reaction. Effects the amount of emulsifier, initiator and organic nano-SiO₂, etc factors on the performance of emulsion polymerization and latex film were investigated. The best test results of composite emulsion of SiO₂ and vinyl acetate-acrylate were obtained by theoretical research and experimental operation: modified nano-SiO₂ content of 3%, emulsifier the content of OP of 3%, potassium persulfate content of the initiator of 0.5%. By infrared spectroscopy, surface of the SiO₂ had been changed, which showed the performance of situ composite of modified nano-SiO2 and vinyl acetate-acrylate emulsion had been significantly improved.
