Description

technical field [0001] The invention relates to the field of marine anticorrosion coatings, in particular to a polymer sulphoaluminate cement-based marine anticorrosion coating modified by nanometer barium phosphate and a preparation method thereof. Background technique [0002] The ocean covers 4 / 5 of the earth, and my country has more than 3 million square kilometers of sea area. The development of marine resources can effectively alleviate the current shortage of resources. Seawater is the largest and highly corrosive natural electrolyte in nature. Seawater contains almost all chemical elements on the earth, and its composition is very complex. In addition, seawater also contains dissolved oxygen, marine organisms, and decaying organic matter. These substances have caused great harm to metal components such as various marine transportation tools, oil production platforms, and marine equipment. With the development of coastal transportation, industrial production, and na...
