Problems solved by technology

[0002] Due to the advantages of quick construction, simple manufacturing process, easy adoption of industrialized production, and short construction and installation period, steel structure buildings have been widely used in industrial buildings or public buildings in various fields, but the high temperature resistance of steel structure materials is poor. It is prone to deformation. In the event of a fire, when the temperature of the steel structure reaches above 500 degrees, it may collapse instantly
Therefore, in order to improve the fire-resistant grade of steel structures, it is necessary to coat fire-resistant coatings on the surface of steel structures. However, the existing fire-resistant coatings for steel structures, especially indoor ultra-thin fire-resistant coatings for steel structures, are all organic solvent-based, flammable and explosive, and difficult to transport and store. All must be implemented in accordance with the requirements of dangerous goods; in addition, it emits a strong smell of harmful substances, which is harmful to the environment and human body, and is not environmentally friendly; and the drying speed is slow during construction, and organic solvents are required, and the construction efficiency is relatively low
