Abstract

The invention discloses an ocean heavy anti-corrosion epoxy aluminum-rare earth-rich nano-coating, which is composed of components A and B with a mass ratio of 18:1 and comprises the following components in parts by mass: 14-18 parts of epoxy resin, 3-6 parts of hydroxyl acrylic resin, 125-145 parts of nano-aluminum powder, 1-2 parts of rare earth powder, 3-6 parts of talcum powder, 2-4 parts of barium sulfate, 3-5 parts of an anti-settling auxiliary agent, 1-2 parts of a dispersing auxiliary agent, and 10-13 parts of a solvent, wherein the component B comprises the following components with contents in parts by mass: 50-60 parts of a curing agent and 40-50 parts of a solvent. The invention also discloses a preparation method of the coating. By adopting the scheme of the invention, the nano-aluminum powder content in a lacquer film is high, the cost is low, the process is simple, and no special equipment is needed. According to the invention, the prepared coating has strong binding force with a matrix, also has relatively good binding force with various other additional coatings, is excellent in corrosion-resistant performance in an ocean atmospheric environment, and long in service life, and is a heavy anti-corrosion coating applicable to iron and steel constructions such as a drilling platform and a bridge in an ocean atmospheric environment.

Description

technical field [0001] The invention relates to a paint technology, in particular to a marine heavy-duty epoxy aluminum-rich rare earth nanometer paint and a preparation method thereof. Background technique [0002] At present, metal corrosion is a very serious problem. It is roughly estimated that the annual loss of metal structures, equipment and materials due to corrosion is approximately equivalent to 20%-40% of the metal output of the year, and more than 100 million tons of metals are scrapped due to corrosion every year in the world, and the economic loss accounts for 100% of the national total. 1.5%-3.5% of the total economic output value. In China, the economic loss caused by metal corrosion is as high as more than 30 billion yuan per year, accounting for 4% of the gross national product. Especially the marine corrosion in the marine environment, the corrosion of metal and other components in the marine environment, the harm it causes is very serious. With the lay...
