Abstract

The invention discloses a marine corrosion resistant coating containing aluminium-manganese-graphite. The coating is prepared from the following raw materials in parts by weight: 50-60 parts of aluminium-manganese-graphite alloy powder, 5-12 parts of organic solvent, 5-15 parts of nano oxide particle reinforcing agent, 1-5 parts of levelling agent, 1-5 parts of epoxy curing agent, 10-15 parts of defoaming agent, 3-8 parts of deionized water, 1-5 parts of binding agent, 1-5 parts of corrosion inhibitor, 1-5 parts of dispersing agent and 1-5 parts of thickening agent. The coating meets the urgent need for solving the problem of marine corrosion of engineering parts, and has important application prospects in marine engineering and corrosion engineering of industrial equipment such as offshore wind farms and the like.

Description

technical field [0001] The invention relates to the field of anticorrosion coatings, in particular to a marine anticorrosion coating containing aluminum, manganese and graphite. 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,...
