Preparation and Coating Properties of Core-Shell Silicon-Acrylic Emulsions

The core structure of the emulsion was hydrolyzed and condensed by vinyltriethoxysilane and phenyltriethoxysilane, and the shell structure was synthesized by radical polymerization of butyl acrylate, methyl methacrylate, and vinyltriethoxysilane. The Zeta potential of the prepared silicone emulsion was maintained at-40 mV. The emulsion has good stability. Transmission electron microscopy can be used to study the core-shell structure of latex particles. The water contact angle of silicone-modified acrylate coating can reach 94°, and its mechanical durability, alkali resistance, and salt corrosion resistance are better than that of pure acrylate coating.
