[0002] Existing flame-retardant materials are mainly composed of flame-retardant cotton and aluminum foil layers. Depending on the usage conditions, aluminum foil layers can be laminated on both the upper and lower surfaces of the cotton body to achieve double-sided flame retardancy. However, the area around the cotton layer is exposed. Due to the limitations of the cotton layer material, it will suffer structural damage, deformation, and shrinkage when exposed to fire, thus affecting its flame-retardant protection effect and making it unusable.

By designing a novel flame-retardant coating, it is possible to ensure that the aluminum foil layer completely covers the inner cotton body, with no exposure of the inner cotton body or the inner lining layer in the flame-retardant coating. The outer surface is completely wrapped by the aluminum foil layer, which greatly improves the flame-retardant ability and service life of the material. At the same time, the flame-retardant coating is folded along the center line and wrapped around the upper and lower surfaces of the inner cotton body, which is convenient for workers to operate and improves production efficiency.
