| Zusammenfassung: | The invention discloses a preparation method of layered doubled hydroxide modified polyacrylate composite emulsion. The preparation method specifically includes the steps that 1, nanoscale layered doubled hydroxide powder is modified with a reactive emulsifier, and modified nanoscale layered doubled hydroxide particles are obtained; 2, the modified nanoscale layered doubled hydroxide particles are dispersed into deionized water to form a modified nanoscale layered doubled hydroxide particle-deionized water dispersion solution, methyl methacrylate and butyl acrylate are mixed to form mixed monomers, and the modified nanoscale layered doubled hydroxide particle-deionized water dispersion solution and the mixed monomers are mixed to form O/W emulsion; 3, the O/W emulsion is heated in a stirring state, an initiator is added when the O/W emulsion is heated to 75 DEG C to 85 DEG C, and the layered doubled hydroxide modified polyacrylate composite emulsion is obtained after a heat preservation reaction.
