The invention relates to the technical field of flame-retardant bisphenol F type polycarbonate, in particular to a preparation method of high-flame-retardant bisphenol F type polycarbonate. A method for preparing bisphenol F polycarbonate through a melt transesterification method by taking the metal carbonate supported super base as a catalyst is not reported. In order to solve the problems, the invention provides the preparation method of the high-flame-retardant bisphenol F type polycarbonate, which comprises the following steps: by taking bisphenol F and diphenyl carbonate as reaction raw materials and a metal carbonate supported super-strong base catalyst as a reaction catalyst, reacting under the protection of gas, thereby obtaining the high-flame-retardant bisphenol F type polycarbonate. According to the method, high-toxicity phosgene raw materials, a large amount of organic solvents and complex wastewater treatment links which are necessary for a traditional phosgene method are completely abandoned, and major safety and environmental hidden dangers are eliminated from the source.
