The invention discloses a tannic acid/furfural-shellac resin anticorrosion coating and a preparation method thereof. The coating comprises using furfural and tannic acid to sequentially modify the shellac resin twice. The modified shellac resin prepared by the method of the invention is used as an anti-corrosion coating agent, and has high anti-corrosion performance, long resistance to neutral salt spray and neutral salt water, low impact strength, high brittleness, and high adhesion, which is beneficial to wet conditions. Environments, such as the ocean, islands and other water or near water environments as a primer for bullets and shells, or as an anti-corrosion protection for devices, equipment, pipelines, and other devices that require brittle damage in harsh working conditions And the method of the present invention is simple in operation, mild in process conditions, and is suitable for industrialized large-scale production. |
