Problems solved by technology

However, traditional solvent-based coatings use solvents containing a large amount of volatile organic compounds. During production and use, these organic solvents will volatilize into the atmosphere, causing pollution to the atmosphere and harming human health. Therefore, the development of environmentally friendly water-based coatings is the general trend

Abstract

The invention belongs to the technical field of water-based coating and particularly relates to environmentally friendly efficient anti-corrosion water-based coating and a synthesis method thereof. The coating is prepared by mixing a component A and a component B in a mass ratio of 1 to (5 to 50); the component A is prepared from 0.05-5.5 parts of polydopamine modified polyaniline / graphene compound and 1-10 parts of deionized water, both in parts by weight; the component B is prepared from the following components in parts by weight: 20-35 parts of water-soluble alkyd resin, 5-15 parts of copolymer polyfunctional compound, 15-25 parts of resin B, 5-10 parts of pigment and 1-5 parts of anti-foaming agent. Marine environment is a harsh and complicated environment, and the severely corrosiveenvironment with interaction of dry-wet salt mist, moist heat, strong ultraviolet and the like in coastal regions causes serious influence on the performance and structural integrity of a sea immersion material. The preparation technology of the environmentally friendly efficient anti-corrosion water-based coating is simple and has relatively low cost and high repeatability, and can greatly prolong the service life of the coated steel. The environmentally friendly efficient anti-corrosion water-based coating has the advantages of low VOC content, little smell, safety and convenience in use, environmental friendliness, excellent corrosion resistance and chemical resistance of coating, low shrinkage, high hydrophobicity and high hardness.

Description

technical field [0001] The invention belongs to the technical field of water-based coatings, in particular to an environment-friendly high-efficiency anti-corrosion water-based coating and a synthesis method thereof. Background technique [0002] The marine environment is a harsh and complex environment. Metals and alloy materials in coastal dry and wet alternate salt spray, humid heat, high ultraviolet rays and other interactive and coordinated heavy corrosion environments have brought great challenges to sea-immersed materials. Fouling and corrosion have great impact on sea-immersed materials performance and structural integrity can be severely impacted. Marine corrosion is the main threat to the safe service of marine engineering, and it also brings huge losses to the national economy. The depth and breadth of human development of the ocean will continue to expand, and will face the challenge of new corrosion problems. Marine corrosion has brought huge economic losses. ...
