The invention provides a heat-conducting insulating composite material and a preparation method of the heat-conducting insulating composite material. The composite material sequentially comprises a conduction layer and a heat dissipation layer according to the distance between the layers and a heat source from the near to the distant, wherein one side of the heat-conducting insulating composite material is a smooth surface, and the other side of the heat-conducting insulating composite material is a rough surface; the smooth surface is used for receiving a heat source, the thermal contact resistance can be greatly reduced through the smooth surface, and the heat energy can be well and rapidly absorbed; the rough surface is a heat dissipation surface and has a honeycomb porous structure, a far infrared radiation coefficient can be improved, convection is accelerated, and the heat dissipation capacity of the material is improved. The heat conductivity coefficient of the composite material ...
