Abstract

The invention provides a marine high-performance anticorrosion coating and a preparation method thereof. The marine high-performance anticorrosion coating is made with, by weight, 60-70 parts of waterborne acrylic resin, 9-14 parts of nano calcium carbonate, 10-30 parts of nano alumina powder, 5-10 parts of sodium dodecyl benzene sulfonate, 3-8 parts of nicotine, 2-4 parts of an anti-settling agent, 2-6 parts of tributyl acetate, 25-40 parts of a filling material, 20-30 parts of an anti-fouling agent, 2-5 parts of an adhesion promoter, 5-15 parts of zein, 90-110 parts of ethanol solution, 2-5parts of glycerol, and 25-50 parts of deionized water. The marine high-performance anticorrosion coating is environmentally friendly, good in thermal stability, corrosion resistance, adhesion and barrier property, and effective in extending the service time of marine coating film, thereby preventing ships from being corroded by sea water.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to a high-performance anti-corrosion paint for ships and a preparation method thereof. Background technique [0002] Water-based coatings are coatings that use water as a solvent or dispersion medium. The earliest commercialized water-based coatings appeared in the 1930s. Based on its compatibility and protection to the environment, as well as the advantages of saving resources and energy, water-based coating products were quickly accepted by the market and gradually developed and expanded. [0003] With the continuous development of my country's industry, the performance requirements of water-based coatings are getting higher and higher. In order to build a resource-saving and environment-friendly society, coatings have begun to develop in the direction of high solid content and water-based solvents. - , SO4 2- , Br - , HCO 3 - (CO 3 2- ), F - There are a large n...
