The best way to catch fire is to prevent fire and the important role of interior decoration materials in preventing fire: when the fire spreads to the flame decoration material, it has good fire protection. First, the fire source decoration material resists fire resistance. The fire source cannot sustain the burning material. We cannot continue to burn. Secondly, when the fire has better fire protection performance in the vicinity of the decoration materials, it can prevent the fire from further spreading, and the time of the fire source will automatically extinguish the burning time. Common market decorative sheet materials are inorganic minerals, metal plates, organic plates, fabrics, wood products, fire-resistant coatings , flame retardants, etc.
The Xinjiang fire-resistant coating layer is coated with a fire-resistant coating of a flammable decorative surface decorative material, thereby improving the fire resistance of the flame. At present, there are mainly high-performance Xinjiang fire-resistant coatings and intumescent non-inflation types. The intumescent fire-resistant coating layer 1 mainly forms a dense carbonized layer after the thermal expansion coating of the material is completed, thereby achieving the purpose of a fire arrester. A large amount of heat of the non-intumescent fire retardant coating is absorbed from the outside, and the protective layer formed on the surface achieves the purpose of fire prevention by oxygen, and the expansion itself does not occur.
According to the requirements of Section 3.4, GB50222-2015 "Code for Fire Protection of Interior Decoration and Decoration Building Design" regarding underground building interior decoration materials, the fire rating requirements are higher than the ground. In underground building fires, the internal decoration materials are the first to face flame baking, and Ordinary decoration materials are flammable organic materials, wood and other materials, which will accelerate the spread of fire and generate a large amount of smoke and toxic gases. During the combustion process, underground buildings are generally closed and smoke from Xinjiang fire-resistant coatings is not easy to discharge. , Will increase the flow of injured parts of the underground space, it is necessary to take effective measures to strengthen the fire prevention performance of interior decoration materials for firefighting underground buildings.
