Fluorescent PVC (polyvinyl chloride) composite membrane material

The invention discloses a fluorescent PVC (polyvinyl chloride) composite film material which comprises two fluorescent films and a hard PVC film, and the two fluorescent films are fixedly adhered to the front side and the back side of the hard PVC film respectively; the fluorescent film comprises the following raw materials in parts by weight: 1-10 parts of fluorescent powder; 20 to 40 parts of glue; 5 to 25 parts of a PVA solution; 1 to 5 parts of a tackifier; the glue is UV (ultraviolet) glue; the preparation process of the fluorescent film comprises the following steps: S1, taking certain parts of fluorescent powder, glue, a PVA solution and a tackifier, putting into a mixing stirrer, stirring, and stopping after stirring for a period of time, so as to obtain a mixture I; through the PVC resin, the heat stabilizer and the diisononyl phthalate, the hard PVC film is stable in performance and high in hardness, so that the hard PVC film is good in tear resistance, and the quality performance of the whole fluor
