The invention discloses a double-faced spray-painted lamp box fabric. The double-faced spray-painted lamp box fabric comprises a fabric body, an upper spray-painted layer and a lower spray-painted layer, wherein the upper spray-painted layer and the lower spray-painted layer are located at two sides of the fabric body respectively; a sun-shading layer is arranged in the fabric body; a ventilationhole is connected with one side of the sun-shading layer; the sun-shading layer is connected with a wear-resisting layer through the ventilation hole; the wear-resisting layer is connected with the upper spray-painted layer; an anti-pressing layer is connected with the other side of the sun-shading layer; the sun-shading layer is connected with a flame-retarding layer through the anti-pressing layer; the flame-retarding layer is connected with the lower spray-painted layer. According to the double-faced spray-painted lamp box fabric disclosed by the invention, the sun-shading layer is arrangedin the fabric body so that the light transmittance of the lamp box fabric is effectively reduced and the display effect is enhanced; one side of the upper spray-painted layer is connected with the wear-resisting layer so that the adaptability of actual application is enhanced; one side of the lower spray-painted layer is connected with the flame-retarding layer so that the safety standard of utilization is improved; two ends of the fabric body are connected with winding shafts and a resetting spring is arranged at one side in each winding shaft, so that the unfolding display effect is better.
