Abstract

The invention discloses a novel steel structure water-based rust conversion solution. The novel steel structure water-based rust conversion solution comprises the following components: composite organic acid, a penetrating agent, nanometer titania and water. The novel steel structure water-based rust conversion solution is mainly used for a rusted steel structure surface, very good rust convertingcan be carried out on a rust layer on the steel structure surface, and after the rust conversion solution is dried, a primer continues to be sprayed. The steel structure water-based rust conversion solution is composed of the environmental-friendly components, and no toxic or harmful components (such as VOC) are contained. When the novel steel structure water-based rust conversion solution is used, the conversion solution and the water-based antirust coating are used successively, a steel structure can be protected to the maximum extent, the steel structure is prevented from being rusted again, the service life of steel is prolonged, large-scale rust removing work is not needed before construction, and a large number of financial resources and labor are saved.

Description

technical field

[0001] The invention relates to a water-based rust conversion solution for steel structures, which belongs to the technical field of anti-corrosion coatings. Background technique

[0002] With the development of my country's iron and steel industry, the application of steel structures in construction projects is increasing. Steel structure has a series of advantages such as high strength, good toughness, convenient fabrication, fast construction speed and short construction period. But there are also obvious weaknesses - easy to corrode. According to statistics, the annual economic loss caused by metal corrosion in the world is about 700 billion US dollars. Due to the incomparable advantages of other materials and methods such as excellent performance, convenient manufacturing and construction, and low price, paint coating anticorrosion often becomes the object of priority when selecting anticorrosion measures.

[0003] For rusty steel, it is also a good m...
