Abstract

The present invention discloses a highly corrosion-resistant anticorrosive coating and a preparation method therefor. The coating comprises the following components in parts by mass: 50 parts of epoxy resin, 20-30 parts of mica iron oxide, 7-15 parts of mica, 18-25 parts of talcum powder, 1-4 parts of iron oxide red, 0.5-2 parts of fumed silica, 0.5-2 parts of a dispersing agent, 0.5-2 parts of a flatting agent, 1-4 parts of a de-foaming agent, 0.8-2.5 parts of a curing agent and 15-25 parts of a solvent. The invention provides a preparation method of the coating. The prepared coating has good performances such as corrosion prevention, adhesive force and stability, and is simple in preparation method and suitable for industrial production.

Description

technical field [0001] The invention relates to a coating, in particular to an anticorrosion coating with high corrosion resistance and a preparation method thereof. Background technique [0002] Anti-corrosion coatings are composed of film-forming substances, pigments and fillers, solvents and various additives. The film-forming substance is the basic composition of the coating, forms the continuous phase of the coating, and plays a major role in the performance of the coating. It is generally an organic polymer material. Pigments and fillers are generally 0.2-10 μm inorganic or organic powders, which can impart color to the coating, improve the anti-corrosion performance of the coating, improve the mechanical properties of the coating and the penetration performance of corrosion-resistant particles, and form the dispersed phase of the coating. The solvent is a volatile organic liquid that reduces the viscosity of the film-forming substance and can dissolve other component...
