This invention provides a flame-retardant and heat-insulating composite material and its preparation method, belonging to the field of flame-retardant and heat-insulating materials. The flame-retardant and heat-insulating composite material provided by this invention includes multiple functional layers and an adhesive layer disposed between adjacent functional layers; each functional layer is independently a heat-insulating cotton pad or a heat-conducting foil; at least one of the outermost layers of the flame-retardant and heat-insulating composite material is a heat-insulating cotton pad; the number of heat-conducting foil layers is not less than two, and adjacent functional layers are not simultaneously heat-conducting foils; the adhesive layer is a high-temperature resistant resin. The heat-insulating cotton pad and heat-conducting foil in the flame-retardant and heat-insulating composite material provided by this invention have flame-retardant properties; when the heat insulation performance is tested using a soldering iron, the temperature on the front of the iron sheet is concentrated at 229°C, while the temperature on the back after passing through the heat-insulating material is uniformly distributed and only 61°C, exhibiting good high-temperature resistance, flame-retardant properties, heat insulation performance, and heat insulation uniformity, and can be used for a long time.
