From the material analysis of color steel plate, the color steel sandwich plate has been color coated steel plate as the surface material, and the core materials mainly include polyphenylene glycol polymer, urethane and rock wool.
At present, most of the internal insulation materials of color steel plate are polystyrene and polyurethane. They have the advantages of light weight, simple operation process and low cost, but they have low ignition point and poor flame retardancy. The ignition point of polystyrene is 345 ℃, while that of wood is 250 ℃ to 300 ℃, which is only a little higher than that of wood, while that of polyurethane is only about 130 ℃.
Polystyrene and polyurethane will produce a large amount of thick smoke when burning. Its components are mainly carbon monoxide, hydrogen cyanide, etc., which is highly toxic.
Color steel plate fire has the characteristics of fast spread speed, many ways of fireworks spread, easy to form three-dimensional fire, toxic gas in combustion products, difficult fire fighting and easy to cause building collapse.
In the era of continuous progress of color steel plate, if you want to completely prevent fire and use safety, you have to choose color steel plate with good fire resistance, such as precision steel coated tile!
