火灾的危害可想而知，因素在一些建筑材料表面要使用防火涂料。防火涂料是一种用于可燃性基材表面，能降低被涂材料表面的可燃性，阻碍火灾的迅速蔓延，用以提高被涂材料耐火极限的一种特种涂料。防火涂料它除了具有阻燃作用以外，还具有防水、防锈、防腐、耐热、耐磨以及涂层坚韧性、黏附性、着色性、易干性和一定的光泽等性能。 　　
其实防火涂料本身具有难燃性或不燃性，使被保护基材不直接与空气接触，延迟物体着火和减少燃烧的速度；它的导热系数也很低，可以延迟火焰温度向被保护基材的传递。防火涂料受热分解出不燃惰性气体，冲淡被保护物体受热分解出的可燃性气体，使之不易燃烧或燃烧速度减慢。这样燃烧的产生和进行必须同时具备三个条件，即可燃物质、助燃剂和火源被切断了。
含氮的防火涂料受热分解出NO、NH3等基团，与有机游离基化合，中断连锁反应，降低温度。膨胀型防火涂料受热膨胀发泡，形成碳质泡沫隔热层封闭被保护的物体，延迟热量与基材的传递，阻止物体着火燃烧或因温度升高而造成的强度下降。

Fire hazard factors one can imagine, in some building materials surface to use fire retardant coating. Fire retardant coating is used with a combustible base surface, can reduce the coated material on the surface of the combustible, hinder the fire spread rapidly, in order to improve coated refractory limit of a special coating. It has a flame retardant effect, also has waterproof, anti-corrosion, rust-proof, heat-resistant, wear-resistant and tough coating, adhesion, color, easy to dry and certain luster properties.

In fact, fire retardant coating itself is flame resistant or incombustible, that is to protect the substrate does not directly contact with air, delay object on fire and reduce the rate of burning; its thermal conductivity is low, can delay the flame temperature to be protecting a substrate transfer. Fire retardant coating of thermal decomposition of a non-flammable inert gas, dilute the protected object heating decomposition of combustible gas, so easy to combustion or burning velocity. Such burning generating and must have three conditions, namely the combustible material, combustion-supporting agent and fire was cut off.
