Self-luminous anticorrosive paint for steel structures in traffic engineering and preparation method of self-luminous anticorrosive paint

Abstract

The invention relates to self-luminous anticorrosive paint for steel structures in traffic engineering and a preparation method of the self-luminous anticorrosive paint. The self-luminous anticorrosive paint is prepared from epoxy resin, a diluting agent, graphene, glass flakes, nano silicon dioxide, zinc powder, filler, a self-luminous material, an antifoaming agent, a dispersing agent, a leveling agent and a curing agent. On the premise that the content of zinc powder in the paint is sharply reduced, problems of poor coating compactness, large quantity of defects such as holes, poor aging resistance, adhesive force and impact resistance, proneness to cracking and peeling and the like of existing conventional surface paint for the steel structures in traffic engineering, energy accumulating and self-luminous performances are achieved, and accordingly special functions including traffic sign warning, traffic flow induction and the like of traffic steel structures such as bridge bodies,guard rails and cable ropes in nighttime and extreme severe environments can be realized while attractiveness of bridges and roads is achieved, and the paint is integrally excellent in technical performance, cost performance and environmental friendliness.

Description

technical field [0001] The invention belongs to the technical field of steel structure corrosion protection, and in particular relates to a self-luminous anti-corrosion paint for traffic engineering steel structures and a preparation method thereof. Background technique [0002] Anti-corrosion coating technology has become the most widely used anti-corrosion process for steel structures in traffic engineering due to its convenient construction and excellent anti-corrosion effect. Conventional measures usually use anti-corrosion paints composed of primers, intermediate paints and topcoats to provide anti-corrosion coatings on the surface of structures. Protect. [0003] However, through many years of actual engineering application, conventional anti-corrosion coatings are limited by their own material properties and processes, and the anti-corrosion effect is poor. The corrosion protection effect on the metal substrate on the surface of the structure is often not ideal, and t...

Problems solved by technology

[0003] However, through many years of actual engineering application, conventional anti-corrosion coatings are limited by their own material properties and processes, and the anti-corrosion effect is poor. The corrosion protection effect on the metal substrate on the surface of the structure is often not ideal, and the coating is prone to cracking, peeling, For problems such as peeling, repairs and maintenance are required within 5 to 1
