Abstract：
 The preparation method of polyvinylidene difluoride modified polyacrylate emulsion includes the following steps: firstly, preparing monomer mixture formed from methyl methacrylate, butyl acrylate and acrylic acid, dissolving polyvinylidene difluoride in said monomer mixture, then dissolving emulsion adjuvant in said mixture to form oil phase for stand-by; dissolving non-ionic emulsifier and anionic emulsifier in water to form water phase, then mixing oil phase and water phase, high-speed stirring them and making them into fine emulsion, adding the fine emulsion and initiating agent into a container under the protection of nitrogen gas, reacting for a period of time, cooling to room temp., regulating pH value to obtain the invented polyvinylidene difluoride modified polyacrylate emulsion. It possesses good cohesive force with base material, and possesses good surface performance of formed film, and has no pollution, can be used for modifying surface of base material in the fields of external wall of building, textile and leather products.
