Abstract: The present invention provides a method for controlling Mooney viscosity of peroxide-cured fluororubber. The method comprises: adding an initiator solution in a continuous supplementary manner during the emulsion polymerization process of a peroxide-cured fluororubber until 5 to 10 minutes before the end of the polymerization reaction; wherein the amount of the initiator solution added initially is 0.1% to 0.5% of the total amount of the polymerization monomer dry materials, and the amount of the initiator solution continuously supplemented is 0.1% to 2% of the total amount of the polymerization monomer dry materials, based on the initiator. The present invention effectively controls the Mooney viscosity value of the peroxide-cured fluororubber within the desired range with small fluctuations by controlling the amount and the manner of addition of the initiator, thereby obtaining a peroxide-cured fluororubber with stable and controllable quality.
