Problems solved by technology

[0002] The existing anti-corrosion coatings for the marine environment are only selected from the aspects of salt spray resistance and seawater resistance, without considering the hydrophobic performance. Due to the wetting of the coating surface with water, some marine organisms and marine pollutants are extremely harmful. It is easy to grow on the surface of the coating and cause coating damage as time goes on. At the same time, the current anti-corrosion coating is not ideal in terms of resistance to sea sand erosion

Abstract

The invention relates to a hydrophobic wear-resistant and corrosion-resistant paint and a method for preparing the same. The paint comprises a component A and a component B, wherein the component A comprises the components in part by weight: 1 part of bisphenol A epoxy resin with an epoxy value of between 0.38 and 0.52 percent, 0.25 to 0.35 part of dimethyl benzene, 0.1 to 0.15 part of butyl acetate, 0.1 to 0.2 part of acrylic resin, 0.2 to 0.4 part of coumarone-indene resin, 0.050 to 0.1 part of titanium white, 0.15 to 0.25 part of spherical ceramic powder, 0.05 to 0.1 part of precipitated barium sulfate, 0.005 to 0.02 part of methyl ethanolamine, 0.005 to 0.02 part of fluorine carbon polymer and 0.005 to 0.02 part of organic siloxane; and the component B comprises the components in partby weight: 1 part of 3,3'-dimetyl-4,4'-diamino dicyclohexyl methane, 0.65 to 0.85 part of mannich base and 0.15 to 0.2 part of alcohol; the component A and the component B are used according to a weight ratio of 100 to 12; and the paint can prevent attachment of pollutants and erosion of sea sand and sea ice.

Description

technical field [0001] The invention relates to a long-acting hydrophobic and wear-resistant anti-corrosion coating for marine structures and a manufacturing method thereof, which are used for anti-corrosion of marine structures such as platforms, docks, bridges and ships. Background technique [0002] The existing anti-corrosion coatings for the marine environment are only selected from the aspects of salt spray resistance and seawater resistance, without considering the hydrophobic performance. Due to the wetting of the coating surface with water, some marine organisms and marine pollutants are extremely harmful. It is easy to grow on the surface of the coating and cause coating damage as time goes on. At the same time, the current anti-corrosion coating is not ideal in terms of resistance to sea sand erosion. Contents of the invention [0003] The object of the present invention is to provide a long-acting hydrophobic and wear-resistant anti-corrosion film with good mec...
