Abstract: Disclosed is a method of improving coagulation of fluororubber emulsion, characterized by adding a solubilizer to a system with the fluororubber emulsion as a stock, including: first adding high purity water to the emulsion, followed by adding a coagulant, and then adding the solubilizer for coagulation. The crumbs resulting from coagulation are loose with low electrical conductivity and moisture content, and are easily washed and dewatered with short drying time; the disclosure reduces product costs and enhances product quality and production efficiency.
