NOVELTY - The utility model relates to the technical field of coating, especially an aqueous ceramic-based graphene heat-conducting radiating coating structure, comprising a bottom layer, a high heat conducting layer, a middle layer, a wearable layer and a radiating surface layer, the utility model can improve the heat conducting performance through the heat conducting layer, increasing the scratch resistance of the coating layer through the wearable layer; nano-silicon dioxide particles; nano-zinc oxide particles; the nano silicon carbide particle not only enhances the wear resistance of the coating layer, but also increases fluidity, reduces the surface tension of the substance, the hollow ceramic particle contains gas with good cold-heat shrinkage resistance, enhancing the elasticity and scratch resistance of the coating, reducing the coating caused by heat expansion and contraction caused by cracking and falling; using the two-dimensional graphene and one-dimensional spherical nano aluminium oxide, aluminium nitride; taking one-dimensional carbon fibre and aluminium oxide fibre as the auxiliary materials, forming a point line structure, making the micro-surface of the coating form a concave shape, improving the infrared radiation emitting amount, so as to form a coating with high radiation and high heat transfer performance.
