Abstract: The title organic-inorganic compound coatings was prepared by hybrid of acrylic emulsion and silica sol through silane coupling agent and proper additives. Compared to the simple bending of polyac-tylate emulsion and silica sol/poly actylate, the silica sol/polyacrylate hybrid emulsion and its coatings film showed better physical and chemical performance and chemical stability. The influence of content of silane coupling agent, and the optimized blend ratio and additive were discussed.

Key words: silica sol, acrylic emulsion, silane coupling agent, organic-inorganic hybrid coatings
