Fireproof paint is a special paint, used to paint on wood, fiberboard, cardboard, plastic and other flammable substrates in the building or for cables, metal components surface, fire protection and decoration. The characteristics of the fireproof coating include: it is inflammable or incombustible, so that the maintenance substrate is not directly in contact with the air, the object is on fire and the speed of incineration is reduced; Low thermal conductivity, which can delay the transfer of flame temperature to the substrate being maintained; Heat decomposition of non-flammable inert gas, weakening the maintenance of the object thermal decomposition of flammable gas, so that it is not easy to burn or slow down the incineration speed; Directly paint on the equipment or primer, without cutting, cutting, winding and other complex processes; No harmful substances, VOC and other components, construction and use of the process will not cause harm to the human body. At present, fireproof coatings are widely used for fire protection of steel structures, which can slow the temperature rise of steel and effectively protect steel components
