The fireproof sheet refers to a new type of sheet with a thickness of 0.2 to 5 mm, which can improve the burning grade and fire endurance of the material to be protected, and is composed of a skeleton material, a binder and a flame retardant. In developed countries, fireproof sheets have been widely used in fire protection of building structures and components, and combustible materials, overcoming the problems in flame retardant impregnation treatment of fire retardant coatings and wood materials.
The purpose is as follows:
(1) For fire protection and decoration of combustible materials: the thickness is usually 0.2 to 0.5 mm, and the combustion performance after combination with combustible materials meets the requirements of Class B1 (flammable) materials.
(2), alternative decorative fire-retardant coatings, used for the protection and decoration of steel structures, building structures and construction, combustible building materials, with a fire resistance of 1.0 to 3.0 hours, and a thickness of usually 0.3 to 5 mm.
(3) For the production of high-grade wooden fire doors, to improve wood utilization and production efficiency, the thickness is usually 0.5 ~ 1.5mm.
