Anti-corrosion graphene coating and use method thereof

Abstract

The invention discloses an anti-corrosion graphene coating. The anti-corrosion graphene coating is characterized by containing the following raw materials in parts by weight: epoxy resin, deionized water, graphene sheets, graphene dispersion liquid, a leveling agent, a wetting and dispersing agent, pigments, an ethanol solvent, an anionic acrylic emulsion, a defoaming agent, an Rs preservative, acuring agent, polyaniline, a film forming aid, isooctyl ester, a thickener, dimethyl fumarate, a mold release preservative, a toughening agent and a silane coupling agent. The preparation method comprises the following steps: (1) mixing, and stirring; (2) adding ingredients, and stirring at a high speed, so as to obtain slurry; (3) adding the slurry into a sand mill, and carrying out sand milling;and (4) putting the slurry into a size mixing tank, and stirring at a high speed, so as obtain the anti-corrosion graphene coating. By utilizing environment-friendly materials, the quality of a product is substantially improved; the time and the materials are saved, the anti-corrosion graphene coating is convenient to use only through thin coating and has excellent properties of water resistance,heat resistance, corrosion resistance, weather resistance, stability and the like.

Description

technical field

[0001] The invention relates to the field of graphene coatings, in particular to a graphene anticorrosion coating and a method for using the same. Background technique

[0002] Anti-corrosion coatings, generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, are an indispensable coating in paint coatings. Conventional anti-corrosion coatings play an anti-corrosion effect on metals under normal conditions and protect the service life of non-ferrous metals; A type of anti-corrosion coating that achieves a longer protection period than conventional anti-corrosion coatings.

[0003] However, the existing anti-corrosion coatings have the following disadvantages: 1. Pollution to the atmosphere; 2. Short service life; 3. Expensive, neither safe nor environmentally friendly; health impact.

[0004] Therefore, it is a problem to be solved urgently to develop a kind of environment-friendly graphene anticorrosion coating, ma...
