Abstract

The invention discloses a marine corrosion-resistant epoxy aluminum-magnesium-nickel rear earth rich nanometer material and a preparation method thereof. The nanometer material is formed by a component 1 and a component 2 according to the mass ratio of 18:1; the component 1 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 nanometer aluminum powders, 25-30 parts of nanometer magnesium powders, 4-8 parts of nanometer nickel powders, 1-2 parts of rear earth powders, 3-6 parts of talcum powders, 2-4 parts of barium sulfate, 3-5 parts of anti-settling additive, 1-2 parts of dispersing additive and 10-13 parts of solvent; and the component 2 comprises the following ingredients by mass part: 50-60 parts of curing agent and 40-50 parts of solvent. The invention further discloses a method for preparing the coating. With the nanometer material, the content of the nanometer aluminum powders in a paint film is high, the cost is low, the process is simple, no special equipment is necessary; as the prepared coating has high binding force with a matrix, and simultaneously has better binding force with other various added coatings as well as has excellent corrosion resistance and long service life in marine atmospheric environment, and can be used as the heavy anti-corrosion coating for such steel structures as drilling platform and bridges in marine atmospheric environments.

Description

technical field [0001] The invention relates to a coating technology, in particular to a marine heavy anti-corrosion epoxy aluminum-magnesium-nickel-rich rare earth nano coating 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 v...
