The steel structure has the characteristics of high strength and light weight, improves efficiency and speed, and is widely used in the construction industry. Moreover, the steel structure has good ductility and shock resistance, and the construction time is short, and it is increasingly used in high-rise construction. However, the high temperature resistance of the steel structure is not very good. In a fire situation, it takes only a quarter of an hour, the temperature of the steel structure will rise to more than 540 degrees, and the steel structure is easily deformed at high temperatures, which in turn causes an accident, so the steel Structural fireproof coatings are produced. The principle of fireproof and heat insulation of ultra-thin or thin-type steel structure fireproof coating is that the fireproof coating layer expands and foams when it is fired, forming a foam. The foam layer not only isolates oxygen, but also has good heat insulation performance because of its loose texture. The rate at which the heat is delayed to the substrate to be protected; according to the physicochemical principle, the process of the foam layer produced by the expansion and expansion of the coating exhibits an endothermic reaction due to the expansion of the volume, and also consumes heat during combustion, which is beneficial to lowering the system. Temperature, the role of these aspects, makes fire retardant coatings produce significant fire and heat insulation. The fireproof and heat insulation principle of the thick steel structure fireproof coating coated on the steel component is that the coating does not substantially change in volume when the fireproof coating is fired, but the thermal conductivity of the coating is very low, and the heat is delayed to the substrate to be protected. At the speed, the coating of the fire retardant coating itself is non-combustible, acts as a barrier to the steel components and prevents heat radiation, and avoids direct attack of the steel components by flames and high temperatures.
