A kind of steel structure low surface treatment anti-corrosion transparent coating and coating process

Abstract

The invention provides a low surface treatment anti-corrosion transparent coating for steel structures, the coating is composed of a primer, an intermediate paint and a top coat, the primer is a two-component epoxy resin containing a penetrating agent, an adhesion promoter, a gloss Modification additives such as stabilizer, nano-oxide and rust conversion agent; intermediate paint is one or both of two-component acrylic or polyurethane, containing modification additives such as matting particles and ultraviolet absorbers; top coat is two-component One or two kinds of polysiloxane or fluorocarbon resin, containing modification additives such as matting particles, ultraviolet absorbers, and nano oxides. Further, the present invention also provides a coating process for the above-mentioned coating. The paint provided by the invention is applied on the steel structure with low surface treatment, and has excellent matrix bonding force, super corrosion resistance and weather resistance, outstanding matt effect and high transparency, making it an anti-corrosion protection Coatings are widely used in the renovation of old industrial areas and the construction of industrial museums in various industries.

Description

technical field [0001] The invention belongs to the technical field of anticorrosion coating for steel structures, and in particular relates to a low surface treatment anticorrosion transparent coating for steel structures and a coating process. Background technique [0002] With the improvement of national environmental protection and the adjustment of urban layout, many historical heavy industrial parks are facing renovation and upgrading or relocation and adjustment, which will result in a large number of old steel structure workshops being left idle. Expansion of its functions is a difficult problem that many cities need to face. [0003] These old factory buildings are symbols of a city in different periods and have witnessed the development of the city. Through renovation and upgrading, they have been endowed with new functions, especially preserved as industrial sites or museums with industrial themes, which has great practical significance. The early workshops mostl...

Problems solved by technology

If it is not reinforced or treated with high-level anti-corrosion treatment, there will be major safety hazards in the subsequent service process

However, the traditional anti-corrosion paint for steel structures has higher requirements for the cleaning of the base layer, and the paint cannot show the original style of the original steel structure, especially as an industrial site or museum, it cannot show heavy industry imprints and historical and cultural inheritance.
