The invention provides a colorful explosion-proof membrane which comprises a PET or TPU layer optical membrane, and the upper surface and the lower surface of the PET or TPU layer optical membrane arecoated with a liquid crystal colorful layer and a PS reflective coating layer which are arranged in a self-orientation mode respectively. An OCA optical film, a hot melt film or a UV tackifier layeris coated between a PET release film and a colorful layer, meanwhile, transfer printing textures are arranged between the optical film and a reflection coating layer, the PS reflection coating layer is a high-reflection sheet-shaped silver or nanometer reflection coating, and roll-to-roll silk-screen printing ink is arranged on the lower surface of the reflection layer. According to the scheme, the use effect of the explosion-proof membrane is effectively improved, the service life of the explosion-proof membrane is effectively prolonged, meanwhile, the production process of the explosion-proof membrane is simplified, an electroplated metal layer is prevented from being adopted, environmental protection is improved, meanwhile, the production quality of the explosion-proof membrane is effectively guaranteed, and the reflection effect on different colors and the blocking effect on infrared rays and ultraviolet rays are improved and stripping of an adhesive layer is avoided.
