Styrene acrylate-siloxane composite emulsion with core-shell structure, and preparation method and use thereof

The present disclosure provides a styrene acrylate-siloxane composite emulsion with a core-shell structure, and a preparation method and use thereof, and relates to the technical field of protective coatings. In the present disclosure, a core emulsion is prepared through two-step emulsification with styrene, an acrylate monomer, a first emulsifying agent, a first initiator, a second initiator, an alkaline reagent, and water as raw materials; then a shell emulsion is prepared with a siloxane monomer, a hydroxyl-containing acrylate monomer, an emulsifying agent, and water as raw materials; and then the core emulsion, the shell emulsion, and an initiator are subjected to a grafting reaction to obtain the styrene acrylate-siloxane composite emulsion with a core-shell structure.
