NOVELTY - The utility model claims a TPU composite film, the TPU composite film comprises a first TPU film layer laminated, graphene conductive layer, a second TPU film layer, adenosine triphosphate flame retardant layer and a radiating layer. wherein graphene conductive layer has good conductivity, the adenosine triphosphate flame retardant layer has good flame retardant effect, when the fire is encountered, adenosine triphosphate adenosine molecule in the adenosine triphosphate flame retardant layer will quickly expand, blocking heat to the second TPU film layer, graphene conductive layer and the first TPU thin film layer transmission, and the radiating layer can effectively conduct the heat to the adenosine triphosphate flame retardant layer, so as to effectively develop the adenosine triphosphate flame retardant layer has good expansion flame retardant effect, the TPU composite film has good fire-retardant effect, ensuring that the TPU composite film still can keep good conductive capability in the fire.
