Abstract
The invention discloses a marine corrosion resistant nano coating rich in graphite. The nano coating 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 graphite powder, 3-6 parts of talcum powder, 2-4 parts of barium sulphate, 3-5 parts of anti-settling aid, 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, 1-2 parts of dispersing aid, 10-13 parts of solvent, 50-60 parts of curing agent and 40-50 parts of solvent. The nano coating has excellent corrosion resistance and long service life and can be applied to heavy corrosion resistance of iron and steel structures such as drilling platforms, bridges and the like in the marine atmospheric environments.
Description
Technical field
The present invention relates to the anticorrosion rich Nano graphite 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.
For one of effective, the most the most frequently used method of conventional hardware protection against corrosion, be at metallic surface coating erosion shield, to completely cut off corrosive medium and metallic matrix.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 when improving protective system barrier propterty always.Such as the quality of coating integral body 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 Nano graphite coating.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the anticorrosion rich Nano graphite coating in a kind of ocean, by the raw material of following parts by weight, made: epoxy resin 14-18 part; Hydroxylated acrylic resin 3-6 part; Nano graphite powder 125-145 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; Flow agent 1-5 part; Epoxy reinforcing agent 1-5 part; Dispersing auxiliary 1-2 part; Solvent 10-13 part; Solidifying agent 50-60 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 structure such as drilling unit, bridge of atmospheric marine environment.
