Abstract

The invention discloses anticorrosive paint and a preparation method thereof. The anticorrosive paint is prepared from the following components in parts by weight: 1 to 5 parts of graphene, 5 to 25 parts of phosphate, 10 to 35 parts of silicon dioxide, 4 to 15 parts of an aniline monomer, 5 to 15 parts of benzenesulfonic acid, 0.8 to 2.8 parts of filling, 3 to 6 parts of resin and 10 to 20 parts of an organic solvent. The preparation method comprises the following steps: mixing the graphene, the phosphate, the silicon dioxide and the aniline monomer; then adding the benzenesulfonic acid for enabling the aniline monomer to be subjected to polymerization reaction; after reacting, removing a solution in a reaction suspension solution to obtain compound powder; mixing the compound powder with the filling, the resin, the organic solvent and water to obtain slurry; then removing the organic solvent and the water in the slurry; grinding to obtain the anticorrosive paint. According to the anticorrosive paint disclosed by the invention, organic matter components are reduced, so that the anticorrosive paint is environment-friendly; the service life of the anticorrosive paint is long; meanwhile, the preparation method of the anticorrosive paint is simple and the production cost is low, so that industrial batch production is easy to realize.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion materials, in particular to an anti-corrosion coating and a preparation method thereof. Background technique [0002] Currently commonly used anti-corrosion coatings contain a large amount of organic matter, which has a harmful effect on the environment, and is limited to the characteristics of the organic matter itself, and the anti-corrosion coatings have poor environmental resistance. Water-soluble coatings are environmentally friendly products that are expected to replace the above-mentioned oil-soluble coating materials. Lamellar structure materials such as mica, glass flakes and conductive polymer materials that can passivate metal surfaces can form a sandwich structure, which is a feasible idea for preparing water-soluble anti-corrosion coatings. [0003] However, the current research mainly stays in mixing the prepared conductive polymer-sheet material with a sandwich structure as ...
