Background
The fireproof coating is used on the surface of a combustible substrate and used for changing the surface combustion characteristic of the material and retarding the rapid spread of fire; or a special type of coating applied to building components to increase the fire endurance of the component. From the old theory of the thickness of the coating layer, the fireproof coating is mainly divided into three main categories: the thickness of the thick fireproof coating on a thick steel structure or a wall body is generally 8-50 mm, so that the fireproof time of the fireproof coating can be kept for 0.5-3 h, the fireproof and heat insulation principle of the thick fireproof coating is that the coating can resist flame and the heat conduction coefficient of the coating is low, and the self heat absorption function can delay the expansion of the coating layer and protect the safety of the steel structure and the wall body, but the coating is thick and the dead weight of a building is increased due to the large consumption of the coating.
In addition, the thick fireproof coating has the advantage of water solubility and fire resistance compared with other fireproof coatings, but after the thick fireproof coating is coated on a steel structure and a wall body, when the fire resistance reaches a certain period, the coating becomes thinner gradually, the fireproof function is reduced, and the appearance is poor.
