Abstract：
 The preparation method of fluororubber modified polyacrylate emulsion includes the following steps: firstly, preparing monomer mixture formed from methyl methacrylate, butyl acrylate and acrylic acid, dissolving the fluororubber said mixture, and dissolving the emulsion adjuvant in said mixture to form oil phase for stand-by; dissoling non-ionic emulsifier and anionic emulsifier in water to form water phase; mixing said oil phase and water phase, stirring at high speed to obtain fine emulsion, adding initiating agent in the fine emulsion, under the protection of nitrogen gas adding fine emulsion, deionized water and initiating agent, then drop adding the fine emulsion in which the initiating agent is added into a container, finally adding initiating agent, regulating pH value to obtain the fluororubber modified polyacrylate emulsion. It possesses good cohesive force with base material and good surface performance of formed film, and has no pollution, so that it can be used for modifying surface of base material in the fields required for resisting pollution, heat resistance, water-proofing property, resistance to chemical reagent and inadhesion property.
