Description

technical field [0001] The invention relates to the technical field of electrode anticorrosion, in particular to a heat-resistant 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 prevent the c...
