Abstract

The invention belongs to the technical field of metal corrosion resistance, and particularly relates to novel paint for anti-fouling and anti-corrosion treatment on a marine metal component. The novel paint comprises the following ingredients: 15-20 parts of epoxy resin, 1-5 parts of a corrosion inhibitor, 15-24 parts of fluorocarbon resin, 1-3 parts of a dispersing agent, 15-25 parts of Al-Zn-Ni alloy powder, 0.6-1 part of a bonding agent, 15-20 parts of an organic solvent, 2-9 parts of an anti-foaming agent, 5-10 parts of a nanometer oxide or a modified nanometer oxide, 1-4 parts of a thickening agent and 10-20 parts of deionized water. A preparation method of the novel paint comprises the following steps: (1) adding the organic solvent, the deionized water, epoxy resin and fluorocarbon resin in sequence according to a certain ratio; (2) adding the anti-foaming agent and the dispersing agent in sequence; (3) adding the Al-Zn-Ni alloy powder, the nanometer oxide or the modified nanometer oxide, the corrosion inhibitor, the thickening agent and the bonding agent in sequence; (4) continuously stirring the mixture to obtain a target product, namely the novel paint. The novel paint is high in bonding property, long in corrosion life, ideal in moisture and heat resistance, and remarkable in environmental protection performance.

Description

technical field [0001] The invention belongs to the technical field of metal anticorrosion, and in particular relates to a novel coating for antifouling and anticorrosion treatment of marine metal components and a preparation method thereof. Background technique [0002] my country has a coastline of more than 18,000 kilometers, rich in marine resources and a thriving marine industry. However, due to the particularity of the seawater environment (containing Cl- and a large number of microorganisms, etc.), the marine environment is very harsh and highly corrosive. Seawater has high salt content and strong conductivity. O2 and CO2 tend to be saturated in the surface seawater, and the pH value reaches about 8.2. The conductivity far exceeds that of river water and rainwater. It is a corrosive natural electrolyte solution that causes seawater The galvanic corrosion effect is caused by the galvanic action of metals immersed in seawater. In addition, there are more than 210,000 k...
