Description

technical field [0001] The invention relates to the field of preparation of nano-composite coatings, in particular to a nano-silicon salt filler zinc-aluminum composite heat-insulating coating and a preparation method thereof. Background technique [0002] The surface of the metal structure exposed to the wild environment is very easy to corrode due to chemical and electrochemical interactions with the surrounding environment. Therefore, it is necessary to coat the surface with an anti-corrosion layer to protect the main body of the metal structure from corrosion. However, when the performance of the anti-corrosion coating material on the surface of the metal structure is poor and damaged, the metal structure body will also be exposed to rust. [0003] At present, the following methods are used: the traditional anti-rust paint coating, the anti-rust paint film cannot completely prevent the hydration oxygen in the air from penetrating, and the polymer paint material has "agin...
