Anti-corrosion antifouling paint and preparation method thereof

Abstract

The invention discloses an anti-corrosion and anti-fouling nano coating. The anti-corrosion and anti-fouling nano coating comprises a matrix component and a curing component, the weight ratio of the matrix component to the curing component is (2-4): 1; the matrix component is mainly prepared from modified graphene, nano silicon dioxide, a surfactant, capsaicin, epoxy resin, gamma-(2, 3-epoxypropoxy) propyltriethoxysilane, phenyltrimethoxysilane and a first catalyst; the curing component is mainly prepared from a composite silane coupling agent, tetraethoxysilane, an anionic surfactant and a second catalyst. The anti-corrosion and anti-fouling paint does not contain volatile solvents, and has the advantages of corrosion resistance, fouling resistance and the like.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to an anti-corrosion and anti-fouling nano-coating and a preparation method thereof. Background technique [0002] As a strong electrolyte, seawater has a strong corrosive effect on most metals such as steel, and the adhesion and fouling of marine organisms on the hull is also quite serious. In the coastal areas of my country, a large number of barnacles, shellfish, Algae, these sea creatures can be seen everywhere in the bottom of ships, docks, bridge piers, and seawater pipes. These marine organisms not only seriously affect the normal operation of the ship's equipment, but also cause the surface roughness of the ship to increase, the mass of the hull increases, and the surface film of the coating is destroyed, thereby accelerating the corrosion of the hull, and the marine organisms adhere to the surface of the hull to increase resistance At the same time, it directly leads to slower ship ...

AI Technical Summary

Problems solved by technology

These marine organisms not only seriously affect the normal operation of ship equipment, but also cause the surface roughness of the ship to increase, the mass of the hull increases, and the surface film of the coating is destroyed, which in turn accelerates the corrosion of the hull. At the same time, it directly leads to slower ship speed, lower ship operating performance, greatly increased energy consumption, and greatly shortened hull life.

The usual marine technology mainly uses poisonous materials to release antifouling, mainly by releasing some copper, tin, mercury, and lead. Although the antifouling effect is obvious, it will endanger the environment and pollute the ocean, resulting in the death of a large number of marine organisms. Seriously destroy the ecological balance
