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.

Abstract

The invention relates to an anti-corrosion coating, in particular to an epoxy glass flake heavy-duty coating and a preparation method thereof. The epoxy glass flake heavy-duty coating is prepared by mixing and curing a component A and a component B. The epoxy glass flake heavy-duty coating can be coated on the surface of a steel structure, and can be taken as a primer together with an epoxy zinc-rich primer. When taken as a finish coat, the anti-corrosion coating has high antirust and anti-corrosion performance. As proved by detection, a paint film does not become foamed or rusty when the salt spray resistance reaches 5,000 hours and has high weather resistance, and the coating and maintaining costs of a steel structure can be lowered. The production method of the epoxy glass flake heavy-duty coating does not need post-treatment, so that the process method is simple, energy is saved, and the cost is low. The component A and the component B can be automatically dried into a film at normal temperature after being uniformly mixed, so that high film forming performance is realized, and the product has high storing stability.

Description

technical field [0001] The invention is an anti-corrosion paint, in particular to an epoxy glass flake heavy-duty anti-corrosion paint and a preparation method thereof. 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...
