Coating applied to marine anchor chain and preparation method of coating

Abstract

The invention belongs to the field of coatings, and particularly relates to a coating applied to a marine anchor chain and a preparation method of the coating. The coating is prepared from the following components in parts by mass: 22 to 36 parts of chlorinated rubber, 22 to 24 parts of vinyl acetate resin, 7 to 9 parts of aluminum powder, 3 to 8 parts of copper chloride, 4 to 8 parts of eugenol,3 to 8 parts of epoxy resin, 1 to 2 parts of zinc sulfate, 1 to 4 parts of talc powder, 3 to 5 parts of nano magnesium hydroxide, 4 to 7 parts of aniline methyl triethoxysilane, 5 to 7 parts of a polypropylene fiber, 0.3 to 0.6 part of a eucalyptus extract, 8 to 9 parts of n-butanol, 16 to 18 parts of vinylbenzene, 5 to 13 parts of casein, 5 to 9 parts of m-phenylenediamine, 0.5 to 1.5 parts of adefoamer, 1 to 4 parts of a drier and 0.05 to 1.5 parts of an anti-mold fungicide. The components of the coating obtained by the preparation method disclosed by the invention are uniformly dispersed and mutually complementary; a C-Cl bond with relatively high polarity is formed, and the metal aluminum powder is added, so that the permeability and the electrochemical corrosion resistance of the coating can be significantly improved; furthermore, a coating film is firm and high in compatibility. The preparation process of the coating disclosed by the invention is simple, comprises few steps andis suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a coating applied to marine anchor chains and a preparation method thereof. Background technique [0002] Compared with the natural conditions on land, the ultraviolet rays, salt spray, temperature and humidity in the marine environment, the temperature and flow velocity of seawater, the dissolved oxygen and salt content in seawater, the impact of waves, the impact of floating objects, marine life, Bacteria in seabed soil will cause corrosion of steel components to varying degrees. The anchor chain is the chain connecting the anchor and the hull, which is used to transmit and buffer the external force on the ship. Because the anchor chain is soaked in seawater all the year round and is in such a harsh corrosive environment for a long time, the anchor chain corrodes very quickly. [0003] Coatings are an important raw material in shipbuilding, providing protection against atta...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a coating applied to marine anchor chains and a preparation method thereof. The components of the coating obtained in the present invention are uniformly dispersed and learn from each other's strengths to complement each other's weaknesses. The Cl bond not only improves the weather resistance of the coating, but also improves the defects of the chlorinated rubber coating such as high brittleness, low toughness, and poor adhesion to the substrate, and the addition of metal aluminum powder can significantly improve the permeability of the coating and resist electrochemical corrosion. , and the coating film is firm and has good compatibility
