Abstract
The invention discloses an oceanic anticorrosive rare-earth-rich nanocoating which is prepared from the following raw materials in parts by weight: 14-18 parts of epoxy resin, 3-6 parts of hydroxy acrylic resin, 125-145 parts of nano rare earth powder, 1-5 parts of an epoxy hardener, 10-15 parts of a defoamer, 3-8 parts of de-ionized water, 1-5 parts of a bonder, 1-5 parts of a corrosion inhibitor, 1-5 parts of a dispersant, 1-5 parts of a thickener, 3-6 parts of talcum powder, 2-4 parts of barium sulfate, 3-5 parts of an anti-settling assistant, 5-12 parts of an organic solvent, 5-15 parts of a nano oxide particle reinforcer and 40-50 parts of a solvent. The nanocoating is excellent in corrosion resistance and long in service life, and can serve as a heavy anti-corrosion coating to be applied to steel and iron structures such as a drilling platform in the oceanic atmospheric environment, a bridge and the like.
Description
Technical field
The present invention relates to the anticorrosion rich rare earth nano coating in a kind of ocean.
Background technology
At present, metallic corrosion is the current very serious problem facing.Guestimate, the loss of metal construction, equipment and the material causing because of corrosion every year, be about as much as the 20%-40% of metal output then, the metal that scrap because of corrosion every year in the whole world reaches more than 100,000,000 tons, and financial loss accounts for the 1.5%-3.5% of total value of production in national economy.In China, the financial loss causing due to metallic corrosion, every year up to more than 30,000,000,000 yuan, accounts for 4% of gross national product.Especially the marine corrosion in ocean environment, the corrosion that the members such as metal occur in ocean environment, the harm that it causes is very serious.Along with the layout of China's "Oceanic" strategy in recent years, the metal equipment corrosion problems such as the oil platform in atmospheric marine environment come into one's own day by day.
At metallic surface coating erosion shield, to completely cut off corrosive medium and metallic matrix for one of effective, the most the most frequently used method of conventional hardware protection against corrosion.Zinc-rich paint is a kind of heavy-duty coating of excellent anti-corrosion performance, and oneself is widely applied to the every field of industrial antisepsis.
Along with the mankind carry out on a large scale drive oing boldly to ocean, marine economy and marine industries are further upgraded and to development in pluralism, people have higher requirement for epoxy zinc-enriched paint, such as permanent protective property energy, low consumption of resources and environmental ecology close friend etc.At present, the exploitation of protective system is no longer the protective of only focusing on coating, and scientific research personnel attempts to improve its over-all properties in improving protective system barrier propterty always.Such as the quality of coating entirety after coating film forming, high resistance to corrosion seawater, adhesion strength etc. are its important features.
Summary of the invention
For the deficiencies in the prior art, technical problem to be solved by this invention is to provide a kind of ocean anticorrosion rich rare earth nano coating.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the anticorrosion rich rare earth nano coating in a kind of ocean, made by the raw material of following parts by weight: epoxy resin 14-18 part; Hydroxylated acrylic resin 3-6 part; Nano rare earth powder 125-145 part; Epoxy reinforcing agent 1-5 part; Defoamer 10-15 part, deionized water 3-8 part; Binding agent 1-5 part; Corrosion inhibitor 1-5 part; Dispersion agent 1-5 part; Thickening material 1-5 part; Talcum powder 3-6 part; Barium sulfate 2-4 part; Anti-settling auxiliary agent 3-5 part; Organic solvent 5-12 part; Nano-oxide particles toughener 5-15 part; Solvent 40-50 part.
Beneficial effect of the present invention: corrosion resistant performance of the present invention is outstanding, long service life, can be applicable to the heavy-duty coating of the iron and steel such as drilling unit, the bridge structure of atmospheric marine environment.
