Environment-friendly fluororubber production process and application thereof

Abstract

The invention belongs to the field of fluorine chemical industry, and particularly relates to an environment-friendly fluororubber production process and application thereof, and the environment-friendly fluororubber production process comprises the following steps: injecting deionized water into a polymerization kettle, and vacuumizing the polymerization kettle; adding a regulator into the polymerization kettle, stirring, pre-heating to a first target temperature, and vacuumizing the polymerization kettle again; raising the temperature to a second target temperature, filling a reaction monomer mixture into the polymerization kettle, adjusting the pressure in the polymerization kettle to target pressure, and adding an initiator with a self-emulsifying effect into the polymerization kettle for polymerization reaction; after the reaction is finished, discharging a reaction monomer mixture, and condensing, washing and drying a reaction product. Compared with the prior art, the problems that in the prior art, PFAS auxiliaries have physiological toxicity and high pollution performance are solved. According to the scheme, the fluorine-containing emulsifier is replaced by the aid with a self-emulsifying effect, so that the fluorine rubber without the emulsifier is produced, and the quality of the fluorine rubber prepared by the method is equivalent to that of an existing product.
