The invention provides a preparation method of a heat exchange composite material with a moisture-proof characteristic and high thermal conductivity, GO and MoS2 are combined, PAM macromolecules with a three-dimensional cross-linked network structure are introduced, the interlayer spacing of layered compounds GO and MoS2 is enlarged, and then the surface of the GO/MoS2/PAM composite material is subjected to hydrophobic modification by using stearic acid with low surface energy; the preparation method specifically comprises the following steps: step 1, firstly, preparing a three-dimensional GO/MoS2 composite material; step 2, then preparing a GO/MoS2/PAM composite material; and step 3, finally preparing the GO/MoS2/PAM composite material with the hydrophobic surface. The heat exchange material is convenient to prepare, water molecules can pass through the heat exchange material, and humidity exchange is achieved while air exchange is conducted on the heat exchange material; and the situations of deformation, b
