The invention provides a multi-layer aerogel composite material and a preparation method thereof, and relates to the field of aerogel, and the preparation method comprises the following steps: step 1, placing an aerogel coiled material in an unreeling device, enabling the unreeled aerogel coiled material to pass through a coating device, wherein the coating device contains a binder, and coating one or two surfaces of the aerogel coiled material with the binder after passing through the coating device; 2, winding the aerogel coiled material coated with the binder around a roll core with the preset diameter for a plurality of layers, and after the binder is cured, obtaining a needed multi-layer composite aerogel tube shell through winding; and 3, cutting one axial side of the aerogel tube shell obtained in the step 2. The multi-layer aerogel composite tube shell or plate is prefabricated in a factory, site construction becomes simple and efficient, the construction quality is easier to guarantee, the labor cost
