Preparation method of epoxy resin long-acting anticorrosive coating

Abstract

The invention provides a preparation method of an epoxy resin long-acting anticorrosive coating. An epoxy glass flakeheavy anticorrosive coating is obtained by mixing and curing a component A and a component B; when the epoxy glass flakeheavy anticorrosive coating provided by the invention is used for coating, the coating can be coated on the surface of a steel structure and also can be matched with epoxy zinc-enriching priming paint to be used as priming paint; when the product is used as finishingpaint to be matched, the product has good rustproof and anticorrosive performances; a detection shows that the salt mist resistance reaches 5000 hours and a paint film is not bubbled and rusted and has good weather resistance; the coating maintaining cost of the steel structure can be reduced; the production method of the epoxy glass flakeheavy anticorrosive coating, provided by the invention, does not need post-treatment, so that the process method is simple, energy sources are saved and the cost is relatively low; after the component A and the component B are uniformly mixed, the mixture can be automatically dried to form the film at a room temperature; and the product has a good film forming performance and good storage stability.

Description

technical field [0001] The invention is an anti-corrosion coating, in particular to a preparation method of an epoxy resin long-acting anti-corrosion coating. Background technique [0002] With the continuous development of the national economy and basic construction, the requirements for anti-corrosion of national key projects and large-scale projects are getting higher and higher. Large-scale steel equipment, components, and pipelines put forward higher requirements for coatings, that is, coatings are required to have excellent corrosion resistance. Rust and corrosion resistance, but also must have good construction, adaptability and durability. Epoxy antirust paints are known to have good chemical resistance and corrosion resistance. [0003] However, the traditional epoxy anti-rust paint has high requirements for the surface treatment of steel structures. When the project that has already been in operation needs to be repaired and painted, a second high-quality rust rem...

Problems solved by technology

[0003] However, the traditional epoxy anti-rust paint has high requirements for the surface treatment of steel structures. When the project that has already been in operation needs to be repaired and painted, a second high-quality rust removal treatment must be carried out, and the maintenance and repair will be repeated every few years. Apply the paint once to prevent rust and corrosion of steel

Therefore, large-scale cleaning and derusting must be carried out before repainting, resulting in a huge investment in manpower and material resources, and factors such as mechanical processing that cannot be performed due to the complex and formed engineering structure, these problems have brought great damage to the construction. Difficulties also limit the application of epoxy resin paint products with excellent anti-corrosion performance in large-scale steel structure maintenance projects. In addition to high maintenance costs, the treatment of the steel structure surface also has a negative impact on the environment.
