Problems solved by technology

[0002] Although steel is non-combustible, it has the characteristics of heat resistance and high temperature resistance, and is easy to conduct heat. The heating of steel structures can cause the following two hazards: on the one hand, because of the high thermal expansion coefficient of steel, it is easy to cause deformation of the structure or elongation of components at high temperatures. When the two sides of the steel are heated unevenly, it is easy to cause the component to bend; on the other hand, the mechanical properties of the steel, such as: yield stress, elastic modulus, etc., gradually decrease with the increase of temperature
When the critical temperature is reached, the steel structure will lose its supporting capacity, causing accidents such as building collapse
In particular, it is pointed out that the maximum rising height of the current fire-fighting ladder is only 100m, which causes great limitations to the fire-fighting and rescue work of high-rise building fires;
[0003] At present, the quality of fireproof coatings for steel structures is uneven, and there are common problems such as poor fireproof performance, low expansion ratio, low structural strength of the expansion layer, and poor water resistance.
