從彩鋼板的材料分析來看，彩鋼夾芯板已彩色涂層鋼板為面材，芯材主要有聚苯乙聚、氨酯、巖棉三種。

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.

目前，大部分彩鋼板內(nèi)保溫材料為聚苯乙烯和聚氨酯，他們具有重量輕、操作工藝簡單和低成本等優(yōu)勢，但是其燃點低、阻燃性差。聚苯乙烯的燃點是345℃，而木材的燃點是250℃至300℃，僅比木材燃點高一點，而聚氨酯燃點僅在130℃左右。
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 ℃.

聚苯乙烯和聚氨酯在燃燒時會產(chǎn)生大量的濃煙，其成分主要是一氧化碳、氰化氫等，煙氣毒性較大。

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.
