Abstract

The invention discloses a marine corrosion resistant coating material containing rare earth. The marine corrosion resistant coating material containing the rare earth is prepared from the following raw materials in parts by weight: 50-60 parts of rare-earth alloy powder, 5-12 parts of organic solvent, 5-15 parts of nano oxide particle reinforcing agent, 1-5 parts of leveling agent, 1-5 parts of epoxy solid enhancer, 10-15 parts of defoamer, 3-8 parts of deionized water, 1-5 parts of binder, 1-5 parts of corrosion inhibitor, 1-5 parts of dispersant and 1-5 parts of thickener. The marine corrosion resistant coating material containing the rare earth has the advantage of meeting the urgent need of solving the problem of marine corrosion of engineering parts, and has an important application prospect in the corrosion engineering of industrial equipment of ocean engineering, offshore wind power and the like.

Description

technical field [0001] The invention relates to the field of anticorrosion coatings, in particular to a rare earth-containing marine anticorrosion coating. Background technique [0002] Offshore and marine engineering equipment is located in an environment with rainy, high temperature, salty fog and strong wind currents. According to the ISO9225 environmental evaluation standard, its service conditions are generally >C5 level, which belongs to the extremely harsh environment. The exposed parts will be subject to the combined effects of strong atmospheric corrosion, electrochemical corrosion and airflow erosion, and the service life of various steel structures is much lower than that of the general inland outdoor environment. For example, the wind power generation equipment in service under marine climate conditions is directly exposed to the extreme corrosive atmosphere due to the external components of the unit such as the nacelle, the engine cover, the tower, the blade ...
