Preparation device and preparation method of heat-conducting and wave-absorbing composite membrane material

The invention provides a preparation device and a preparation method of a heat-conducting and wave-absorbing composite membrane material, and belongs to the field of manufacturing of composite functional materials. The preparation device of the heat-conducting and wave-absorbing composite membrane material comprises a first unwinding unit, a second unwinding unit, a base, a membrane material conveying unit, a first calendering unit, a stripping unit, a third unwinding unit, a second calendering unit and a heating and curing unit. The first unwinding unit and the second unwinding unit are respectively used for providing an upper film and a bottom film; the first calendaring unit is used for carrying out first calendaring on the upper film, the bottom film and the molten heat-conducting phase-change material on the calendaring platform; the stripping unit is configured to be capable of stripping the upper film which is calendered for the first time; the third unwinding unit is used for providing a new upper fil
