Problems solved by technology

[0004] The current anti-corrosion coatings, because the main chain in the film-forming material is composed of C-C bonds, are prone to chemical bond breakage under the irradiation of ultraviolet light, thus losing the anti-corrosion function, resulting in a short anti-corrosion period; therefore, the development of long-acting Durable anti-corrosion coatings have become an important direction of current coatings research, the key is to prepare high-performance resins and high-performance long-term anti-corrosion additives

Abstract

The invention belongs to the technical field of anticorrosive coating, and particularly relates to long-lasting anticorrosive finishing paint for a metal substrate and a preparation method thereof. The long-lasting anticorrosive finishing paint comprises a component A and a component B, wherein the component A comprises the following raw materials in parts by weight: 35-45 parts of an epoxy-organosilicone resin modified acrylate-polyurethane emulsion, 10-15 parts of functionalized modified graphene, 12-18 parts of fillers, 5-10 parts of a pigment, 8-12 parts of a cosolvent, 0.3-0.8 part of a defoaming agent, 0.5-1 part of a leveling agent, 0.5-1 part of a thickening agent, 0.5-1 part of a water-based drier, 0.8-1 part of a wetting agent and 20-30 parts of deionized water; the component B comprises the following raw materials in parts by weight: 55-65 parts of an isocyanate curing agent and 35-45 parts of a cosolvent. The long-lasting anticorrosive finishing paint for the metal substrate has the advantages of long-lasting excellent anticorrosive performance, strong substrate adhesion, high mechanical strength, excellent friction resistance, excellent salt spray resistance, strong construction adaptability and the like.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion coatings, and in particular relates to a long-acting anti-corrosion finish paint for metal substrates and a preparation method thereof. Background technique [0002] Steel is the most widely used metal with the widest range of applications. Protecting steel, retarding its corrosion, and prolonging the life of steel products are the most important anti-corrosion work. In the field of corrosion and anti-corrosion, the most concerned is the corrosion and protection of steel. In practice, more anti-corrosion Corrosion methods mainly use corrosion inhibitors, electrochemical protection (including cathodic protection and anodic protection), the use of anti-corrosion coatings and anti-corrosion coatings. In industrially developed countries, the direct economic loss caused by corrosion accounts for 1% to 4% of the total output value of the national economy, the annual corroded and rusted steel acc...
