The invention relates to the technical field of films, in particular to a flame-retardant ultraviolet-proof PET film and a preparation method thereof. The flame-retardant ultraviolet-proof PET film consists of 20-35 parts by weight of PET ultraviolet-proof master batch, 55-80 parts by weight of PET resin, 0.1-3 parts by weight of light stabilizer and 0.6-1 part by weight of flame retardant; the PET ultraviolet-proof master batch comprises the following components: 1-30 parts of nano cesium tungsten bronze particles, 1.5-30 parts of nano ATO (antimony doped tin dioxide) and 0.1-3 parts of ultraviolet absorbent; the flame-retardant ultraviolet-proof PET film can be used for preparing laminated glass, building curtain walls, doors and windows, ceilings, vehicle windows, electric appliance windows and advertising screens, and has the advantages of good flame-retardant property, high surface hardness, ultraviolet resistance, heat insulation and preservation and the like. |
