The invention discloses a PVPF fluorocarbon composite film. The PVPF fluorocarbon composite film is prepared from, by mass, 23%-39% of polyvinylidene fluoride, 42%-56% of polymethyl methacrylate, 0.2%-0.8% of a UV770 light stabilizer, 0.2%-0.8% of a UV245 light stabilizer, 0.5%-2% of a UV328 light stabilizer and 16%-20% of an acrylate copolymer, wherein the total mass percent of the components is 100%. According to the PVPF fluorocarbon composite film, the involved three ultraviolet light absorbers absorb ultraviolet light with different wavelengths respectively, and the ultraviolet light absorption effect is improved; meanwhile, under the condition, the acrylate copolymer can increase the merging degree among the three light stabilizers, the polyvinylidene fluoride and the polymethyl methacrylate, and therefore ultraviolet-radiation-resistant functional areas of the PVPF fluorocarbon composite film are uniform and continuous.
