Description

technical field [0001] The invention relates to the technical field of electrode anticorrosion, in particular to an environment-friendly aluminum electrode anticorrosion coating and a preparation method thereof. Background technique [0002] The anti-corrosion of metal coating is one of the important methods of metal anti-corrosion, and the coating itself only plays a passive physical isolation role, that is, to prevent the direct contact between the metal surface and the environmental medium, because there may be some defects (such as micropores) inside the coating ), so the metal cannot be adequately protected. In order to improve its active corrosion resistance, inorganic or organic corrosion inhibitors are added directly or indirectly. The corrosion inhibitor added directly may interact with the coating, reducing the strength of the coating and causing unnecessary waste. The indirect method is mainly to load the corrosion inhibitor through the carrier material to preven...

[0004] Regarding the functional modification of mesoporous SiO2 microspheres, some studies have used the method of layer-by-layer self-assembly to form multi-layer polyelectrolytes on the surface of mesoporous SiO2 microspheres. The purpose of controlled release of corrosion agent; but because this modification method is more complicated, it is not easy for industrial production, so the development of simple and novel method of surface modification of mesoporous SiO2 microspheres has become the research direction of people
