  • Patent number: 11046816
    Abstract: Disclosed are a fluorine-silicon-containing polyphosphate ester and method for preparation thereof, having a chemical structural formula of: wherein R1 is R2 is n=10˜100. The fluorine-silicon-containing polyphosphate ester of the present invention uses silicon phosphorus and fluorine for improving flame retardancy. Phosphorus catalyzes the system to form a phosphorus-rich carbon layer, performing a protective-layer function and thereby preventing further breakdown of the epoxy resin. The silicon-containing epoxy resin forms a silica-containing carbon layer during the process of combustion, strengthening the carbon-layer structure and further improving the protective function of the carbon-layer. The introduction of elemental fluorine improves the thermal stability of the epoxy resin, thereby improving the flame retardancy performance of the system.
